Ushering in XRP’s DeFi era:...

XRP Ledger — Ethereum and XRP Ledger — Wanchain bridges are live and operational!Since 2017, Wanchain has been on a mission to drive blockchain adoption through interoperability by building fully decentralised bridges connecting the world’s many siloed blockchain networks. After building an industry-leading decentralised blockchain interoperability framework — connecting Bitcoin, Ethereum, Wanchain, EOSIO and Binance Smart Chain — the Wanchain team continues to make strides.Already, in the first few months of 2021, the Wanchain team successfully launched the world’s first truly decentralised Bitcoin — Ethereum direct bridge and released a decentralised direct bridge connecting the Binance Smart Chain and Ethereum. Now, the Wanchain team is pleased to announce that cross-chain bridges connecting XRP Ledger, Wanchain and Ethereum are live and operational on each network’s mainnet!XRP’s DeFi eraDeFi is one of the most important growth drivers in the blockchain industry. However, due to Ethereum’s dominance and the nature of siloed blockchains, most tokens and their holders are unable to take advantage of the innovations of DeFi. Thanks to Wanchain’s new XRP Ledger — Ethereum and XRP Ledger — Wanchain bridges, XRP holders need no longer count themselves among the siloed majority.Effective immediately, XRP token holders can put their XRP to work and engage with the world’s many DeFi applications such as WanSwap, an innovative cross-chain DEX. In other words, XRP holders can now securely use their XRP to farm, mine and provide liquidity rather than simply leaving their tokens, inactive, in wallets and exchanges. XRP tokens can now, finally, engage with DeFi applications and reach their full potential.Under the hood: XRP integrationNote: Cross-chain-enabled XRP tokens are collectively referred to as wanXRP. As required, XRP tokens on Ethereum are referred to as wanXRP@Ethereum and XRP tokens on Wanchain are referred to as wanXRP@Wanchain.Cross-chain-enabled XRP tokens are made possible by Wanchain’s Universal Multichain Bridges. Fundamental to this cross-chain mechanism is Wanchain’s Storeman Group, consisting of 25 truly decentralized Storeman Nodes.When a user initiates a transaction to move their XRP tokens to a DeFi-friendly, smart contract-compatible blockchain, Wanchain’s Storeman Group transfers the relevant XRP tokens to a locked account on the XRP Ledger. The Storeman Group then mints the corresponding tokens on either Ethereum (as wanXRP@Ethereum) or Wanchain (as wanXRP@Wanchain).Swapping wanXRP between Ethereum and Wanchain is a simple affair, built on existing ERC20/WRC20 bridges. When such a transaction is required, the same Storeman Group both burns the wanXRP on the origin chain and mints new wanXRP on the destination chain.The following cross-chain bridges now are now available for XRP holders:XRP Ledger — Wanchain bridge: XRP@XRP Ledger ←→ wanXRP@WanchainXRP Ledger — Ethereum bridge: XRP@XRP Ledger ←→ wanXRP@EthereumWanchain — Ethereum bridge: wanXRP@Wanchain ←→ wanXRP@EthereumAt the wheel: XRP cross-chain transactionsThere are two primary ways for XRP holders to initiate cross-chain transactions:Using the Wanchain desktop walletUsing WanBridge Web1) Using the Wanchain desktop walletSelect “Cross Chain” in the sidebar then click “More Tokens”Add your preferred bridge by clicking the star.

Layer 2! Full EVM compatibi...

We are happy to announce that the Wanchain Mainnet will undergo a hard fork — dubbed “Jupiter” — once the Mainnet’s Galaxy Consensus Epoch ID hits 18732. This is expected to occur on April 15th at 0:00 am UTC. All Wanchain PoS validator nodes and other relevant nodes, such as those belonging to exchanges, wallets, etc., must update their GWAN to version 2.2.0 before that time to avoid block synchronisation issues.The “Jupiter” hard fork makes Wanchain fully compatible with Ethereum. This paves the way for the launch of Wanchain’s highly anticipated Ethereum Layer-2 solution. The “Jupiter” hard fork also gives Wanchain access to popular Ethereum-based tools such as MetaMask.New features1. Makes Wanchain fully compatible with the EIP-155 protocol2. Changes Wanchain’s Mainnet chain ID to 8883. Changes Wanchain’s Testnet chain ID to 9994. Enables seamless migration of Ethereum DApps to Wanchain, including but not limited to MetaMask, Remix and Truffle5. Enables Wanchain’s Ethereum Layer-2 solutionPlease also note that the “Jupiter” hard fork maintains compatibility with existing Wanchain tools, SDKs and applications.Update instructionsThere are two basic methods to complete the update: script update and manual update.Script updateThe Wanchain team has prepared a simple update script. Users can execute the following script after logging into their cloud service node with SSH:$ rm updateMainnetValidator.sh$ wget https://raw.githubusercontent.com/wanchain/go-wanchain/develop/loadScript/updateMainnetValidator.sh && chmod +x updateMainnetValidator.sh && ./updateMainnetValidator.shFurther details are available on explorewanchain.org.Manual updateIf you are not in a standard operating environment, you can download the version 2.2.0 binary file from the release page. Then, you can simply manually replace and upgrade the GWAN node.If you have any questions, please reach out to the team in Wanchain’s official tech support group on Telegram.Thank you for your continued support.

The Wanchain-0Chain partnership brings together decades of global experience in business and technology development to empower developers to build groundbreaking cross-chain applications to power the future of DeFi. Just as importantly, the two innovative companies share a vision for the future of blockchain.Wanchain is the world’s premiere decentralised blockchain interoperability solution. They have been building their cross-chain infrastructure since 2017. In early 2021, Wanchain launched the world’s 1st decentralised BTC-ETH direct bridge. Wanchain also offers decentralised bridges connecting Bitcoin, Ethereum, EOSIO, XRP Ledger and Binance Smart Chain, with other chains such as Polkadot on the horizon. All of Wanchain’s different cross-chain integrations are supported by Universal Multichain Bridges powered by unified decentralised collateral pools, maintained by Wanchain’s Storeman nodes.0Chain offers an enterprise-grade decentralised storage network (DSN) at the edge cloud with core-cloud prices; all the while maintaining high data availability and redundancy, low latency, as well as enabling data privacy & protection regulatory compliance (GDPR) by design.“0Chain’s approach to decentralisation is a perfect philosophical fit for Wanchain,” said Li Ni, Wanchain VP of Business Development and Operations. “Together, we will unlock the full potential of true DeFi.”The scope of the partnership is threefold:0Chain will launch and operate a Wanchain Storeman node, beginning with the fifth Storeman Group. 0Chain’s Storeman node is the first step towards bringing 0Chain’s decentralised storage to WanChain’s users and clientele.Wanchain and 0Chain will create and provide initial liquidity for a WAN/ZCN pair on Wanswap, a community-run cross-chain DEX. This is in addition to the existing WASP/ZCN pair that’s been recently added to WanSwap.Wanchain and 0Chain will jointly determine the feasibility of integrating 0Chain’s decentralised & distributed storage technology into Wanchain’s cross-chain infrastructure.As an indication of commitment to the partnership, Wanchain and 0Chain have completed a token swap.Mo Siam, 0Chain Director of Operations, notes that “Wanchain’s cross-chain infrastructure and T-Bridge framework complements and enables 0Chain’s vision in bringing enterprise grade decentralised storage to multiple chains, whether private or public, seamlessly.We anticipate the next wave in DeFi shall be one that unlocks value from data sets; and the underlying bedrock for this wave shall be interoperability and decentralised storage networks flexible enough to provide high throughput, compete with incumbents on functionality, compliance and cost; yet securely & verifiably store and keep data ownership & control in the hands of its true owners; those that create, generate or buy it.”About 0Chain0Chain is a high-performance decentralised storage network designed to eliminate business threats such as censorship, privacy liability and data breach. 0Chain helps entities achieve GDPR compliance, localisation, tokenisation and monetises private data sharing.The decentralised platform offers high performance, high quality of service, collaboration, localisation, and streaming to address a broad spectrum of applications.Telegram | Telegram Announcements Channel | 0Chain Forum | Twitter | Reddit | FacebookAbout WanchainTrue DeFi is interoperable — Wanchain is the world’s premiere decentralised blockchain interoperability solution.

Live on Wanchain: Decentral...

Live on Wanchain: Decentralised Binance Smart Chain — Ethereum direct bridgeAfter launching the world’s first truly decentralised Bitcoin — Ethereum direct bridge, the Wanchain team is pleased to reveal a new decentralised direct bridge connecting the Binance Smart Chain and Ethereum! With this integration complete, the Binance Smart Chain joins Bitcoin, Ethereum, Wanchain and EOSIO (with XRP Ledger and Polkadot soon to follow! ) on the ever-growing list of public chains that form the Wanchain ecosystemBinance Smart ChainThe Binance Smart Chain (BSC) officially launched last year, sporting EVM-compatibility and a Proof of Staked Authority consensus algorithm. Backed by industry giant Binance, BSC has made great strides in pushing DeFi beyond the familiar confines of Ethereum.Under the hood: BSC IntegrationBSC cross-chain integration is made possible by Wanchain’s Universal Multichain Bridges. Fundamental to this cross-chain mechanism is Wanchain’s Storeman Group, consisting of 25 truly decentralised Storeman Nodes.There are currently four basic scenarios relevant to this integration:1) Original Ethereum-based tokens (e.g., UNI, LINK, etc.) to BSCWhen a user initiates a cross-chain transaction to move an original Ethereum-based token to BSC, Wanchain’s Storeman Group first locks the token on Ethereum before minting a new token on BSC.2) Mapped Ethereum-based tokens (e.g., BTC@Ethereum, XRP@Ethereum, etc.) to BSCWhen a user initiates a cross-chain transaction to move a mapped Ethereum-based token to BSC, Wanchain’s Storeman Group first burns the token on Ethereum before unlocking the original token or minting a new token on BSC, as appropriate.3) Original BSC-based tokens to EthereumWhen a user initiates a cross-chain transaction to move an original BSC-based token to Ethereum, Wanchain’s Storeman Group first locks the token on BSC before minting a new token on Ethereum.4) Mapped BSC-based tokens (e.g., FNX@BSC, etc.) to EthereumWhen a user initiates a cross-chain transaction to move a mapped BSC-based token to Ethereum, Wanchain’s Storeman Group first burns the token on BSC before unlocking the original token or minting a new token on Ethereum, as appropriate.The innovation underlying decentralised direct bridgesThe ability to achieve decentralised Layer 1-to-Layer 1 direct bridges, such as Bitcoin — Ethereum and Binance Smart Chain — Ethereum, without relying a router is an innovation made possible by Wanchain’s Universal Multichain Bridges.Wanchain’s Universal Multichain Bridges, powered by unified decentralised collateral pools and maintained by Wanchain’s Storeman nodes, support all of Wanchain’s cross-chain integrations. This design structure reduces the complexity of cross-chain transactions while making them more convenient — all without sacrificing security. Wanchain’s Universal Multichain Bridges are unmatched in the industry.The door goes both ways: an integration of great significanceThough BSC supports all sorts of different projects, there is no doubt that the catalyst to its rise has been DeFi. From PancakeSwap to Autofarm, BSC-native DApps continue to lead the sector’s TVL growth.Naturally, this incredible growth has attracted a slew of new projects and users to BSC. However, established projects on other public chains — and more importantly, their users — remain isolated, unable to benefit from BSC’s DeFi ecosystem. The reverse is also true. All projects and users would benefit from a safe, truly decentralised mechanism to engage with one another.This situation is just one of thousands that highlight the vital need for blockchain interoperability. Siloed blockchains harm more than they help — and it is always the end users who suffer.Oh, we get by with a little help from our friendsThe first project to take advantage of the new decentralised BSC — Ethereum direct bridge is FinNexus, DeFi platform built on Wanchain and specialized in options and financial derivatives. FinNexus is using the decentralized BSC — Ethereum direct bridge as part of their new liquidity mining program.All users can currently transfer their FNX tokens between Ethereum and BSC using Wanchain’s Desktop Wallet or in-browser using WanBridge. The Wanchain team will gradually add bridges between BSC and other public chains, increasing the variety of BSC-assets moving through the Wanchain ecosystem.About WanchainTrue DeFi is interoperable — Wanchain is the world’s premiere decentralised blockchain interoperability solution.

A long time coming: XRP now cross-chain compatible with Wanchain and Ethereum testnetThe Wanchain team is pleased to reveal that cross-chain bridges connecting Wanchain’s testnet, Ethereum’s Rinkeby testnet and the XRP Ledger’s testnet are live and operational! In other words, XRP can now move freely between these three networks — in a truly decentralised way — thanks to Wanchain’s Storeman nodes. More importantly, XRP token holders are now poised to put their XRP to work and engage with the world’s many DeFi applications.The XRP Ledger is an open-source and decentralised blockchain built to efficiently settle transactions. The XRP Ledger’s native cryptocurrency is XRP — one of the world’s 10 largest cryptocurrencies by market cap — and was built specifically for payments. XRP is faster, cheaper and greener than any other digital asset.Wanchain’s Universal Multichain Bridges sit at the bleeding edge of blockchain interoperability solutions. Unmatched in the industry, the key innovation of this unique cross-chain mechanism is that every single cross-chain bridge is powered by the same, unified collateral pool, maintained by Wanchain’s Storeman nodes. This design structure reduces the complexity of cross-chain transactions while making them more convenient — all without sacrificing security. Wanchain’s Universal Multichain Bridges are a true game changer in the field of blockchain interoperability!Under the hood: XRP IntegrationNote: The cross-chain-enabled XRP tokens are collectively referred to as wanXRP.

There are two basic requirements to running a Storeman node:WAN tokens. A minimum of 10,000 WAN must be staked in order to run a Storeman node. The 24 Storeman nodes with the largest total stakes will be selected. Your node’s total stake is the sum of your own WAN tokens, and tokens staked via “Partner-In” and tokens staked by your delegates.A cloud service on AWS, Google Cloud or equivalent to deploy your Storeman node.For the detailed operations of how to set up a Storeman, please go to Wanchain 5.0 Mainnet Storeman Setup Guide.Note: If you are currently operating a Storeman node and do not wish to participate in the fifth Storeman Group selection, please be sure to withdraw your node using the Wanchain Wallet prior to the start of the next selection period (beginning April 1, 2021 at 04:00 AM UTC). Your staked funds will automatically be returned to your wallet on April 10th, 2021. Node rewards will continue to be issued daily during this withdrawal period. All nodes that are not successfully withdrawn prior to the start of the next selection period will be eligible for selection.About WanchainTrue DeFi is interoperable — Wanchain is the world’s premiere decentralised blockchain interoperability solution.

Today, hundreds of heterogenous blockchains exist. The vast majority of these are siloed — making it impossible for them to reach their full potential. The cost of this lost potential isn’t borne by each individual project, but by their end users: the people. Therefore, as the blockchain industry continues to mature and grow, the need for blockchain interoperability becomes ever more vital.On this front, Wanchain, the world’s premiere decentralised blockchain interoperability solution, is leading the charge. With the launch of Wanchain’s Universal Multichain Bridges, BTC, ETH, EOS and a slew of ERC-20 tokens — USDT, USDC, UNI, SUSHI and LINK, just to name a few — are now moving freely between their native chains, Ethereum and Wanchain. But, as ERC-20 tokens continue to thrive in the DeFi and NFT era, the time has come to prioritise the volume of integrations.With this in mind, we are pleased to announce that applications for all ERC-20 token integrations are open. To apply, simply fill out the application form. All approved submissions will be integrated into Wanchain’s industry-best decentralised cross-chain infrastructure.Don’t wait! Say no to silos!

The next era of DeFi is here!After much anticipation, Wanchain’s 4th Storeman group have begun their invaluable work, marking the debut of Wanchain’s Universal Multi-chain Bridges with Shared Staking Assets! This new cross-chain mechanism introduces two key advances:Shared staking assets. All staked wanBridges’ assets now power the same collateral pool.BTC-ETH direct bridge. BTC can be directly transferred to the Ethereum network without requiring Wanchain as a router.Naturally, a development as monumental as a direct BTC-ETH bridge necessitates an upgrade to the BTC-ETH cross-chain contract. As such, existing wanBTC holders must first convert their tokens before having access to the BTC-Ethereum direct bridge.Before beginning, please carefully note the following:The old BTC cross-chain token is now displayed as wanOBTC in all Wanchain wallet and DAPP interfaces.The new BTC-ETH direct bridge token is now displayed as wanBTC.Converting wanOBTC to wanBTC is a painless endeavour thanks to WanMask and WanSwap, the world’s first truly decentralised cross-chain AMM DEX. The simple process is described below:1. Visit wanswap.finance and connect your WanMask wallet2. Select wanOBTC and wanBTC as your starting and ending tokens, respectively3. Input the quantity of wanOBTC to convert and click “Approve wanOBTC.” The exchange rate between wanOBTC and wanBTC is exactly 1:1.https://wanswap.finance/#/swapPlease note that, for the time being, both wanOBTC and wanBTC will remain open for trading. Nevertheless, it is strongly recommended that you convert your tokens as soon as possible.The Wanchain teamMarch 9, 2021About WanchainWanchain is the infrastructure connecting the decentralised financial world.

Wanchain — Multi-chain Brid...

Wanchain — Multi-chain Bridges Is Live On Mainnet Featured With BTC-Ethereum Direct Bridge And Shared Staking AssetsOn February 26, 2021, the Wanchain team successfully released a brand-new version of cross-chain mechanism — Universal Multi-chain Bridges with Shared Staking Assets after four-months of research and development since Wanchain 5.0. Compared to the previous cross-chain mechanism, the two most prominent highlights of the Multi-chain Bridges are:The shared staking assets, that is, all the wanBridges’ staking assets are shared in the same collateral pool;The BTC-Ethereum direct bridge, that is, BTC can be directly cross-chain transferred to Ethereum without Wanchain as a router.The latest version of WanDesktop Wallet (V1.5.0) now supports the Multi-chain Bridges mechanism. The latest version of WanWallet Desktop is available for download right now! After the next Storeman Group enters the working status on March 9, you can directly cross-chain transfer your BTC from Bitcoin to Ethereum.Here is the download link of WanWallet Desktop:Get Started - WanchainHighlighted Features of Universal Multi-chain Bridges with Shared Staking Assets1. A Storeman Group with shared staking assets enables management of all wanBridgesFor Wanchain 5.0, there is a one-to-one correspondence between a wanBridge and a Storeman Group. Therefore, to connect any two public chains, at least one Storeman Group must be created between the two. Under this mechanism, if a Storeman node wants to participate in multiple wanBridges of connecting different public chains, the node operator must run multiple Storeman nodes in different Storeman Groups. Obviously, this situation increases the difficulty of operation for node operators. The deposit funds among different Storeman Groups are independent and cannot share the cross-chain quotas with each other. So, the utilization rate of the deposits is low, which results in the intensive economic bandwidth of busy wanBridges and wastes economic bandwidth of leisure wanBridges. Theoretically, this mechanism has a small security risk of collusion among Storeman nodes. (The left part of the picture below shows the Wanchain 5.0 cross-chain mechanism).For the reasons above, considering the efficient utilization of resources, the improvement of cross-chain security and the optimization of user convenience, the Wanchain cross-chain mechanism has undergone one more major upgrading on the basis of 5.0. The new version of the cross-chain mechanism is called Universal Multi-chain Bridges With Shared Staking Assets, referred to as “Multi-chain Bridges” for short.The Multi-chain Bridge mechanism is a novel cross-chain solution proposed by the Wanchain team to provide a high level of security and scalability. In this new mechanism, all wanBridges are run by a combined Storeman group with a shared staking collateral pool. This design reduces the complexity of the cross-chain process and ensures that all the cross-chain assets can freely “flow” between any chains. Moreover, it increases the maximum cross-chain capacity of a single bridge in security precondition. (The right part of the picture below shows Wanchain’s brand-new cross-chain mechanism “Multi-chain Bridges”).How can the staking assets from different Storeman nodes be used as the common collateral and be shared among multiple wanBridges?In the Multi-chain Bridge mechanism, once the Storeman nodes stake their assets to the wanBridges, those staked assets will be calculated into a common collateral pool for all bridges. Currently, the only supported type of staked asset is WAN, and support for multiple crypto assets in the future is also being considered by our team. The amount of collateral for a wanBridge is determined by the token price and the quantity of all assets in that Storeman Group where this wanBridge is. As the staking assets of the collateral are shared by all bridges, the cross-chain quota for each wanBridge is also shared by all bridges.Let’s take a look at a specific example to illustrate the dynamic adjustment of the cross-chain quota for each bridge based on the shared staking assets mechanism. (To make it easier to explain, we simplified some complicated factors in the example below):Assuming that the Storeman Group supports three wanBridges: BTC-Ethereum, Ethereum-Wanchain, and BTC-Wanchain. The total staking amount of the group is 1,500K WAN (assuming 1WAN=1USDT, and the WAN price stays the same). The collateral rate of the group is 150%.In the initial stage, BTC-Ethereum, Ethereum-Wanchain, and BTC-Wanchain share the common staking assets which are equivalent to 1,500K USDT, and the maximum cross-chain quota for each bridge is 1,000K USDT (because the collateral rate of the group is 150%).After a period of time, there are 200K USDT worth of BTC cross-chain transferred from the Bitcoin network to Ethereum, and 600K USDT worth of ETH cross-chain transferred from Ethereum to Wanchain.Finally, the three bridges, BTC-Ethereum, Ethereum-Wanchain and BTC-Wanchain, still share the collateral amount equivalent to 1500K USDT. However, due to the cross-chain transfer of 200K USDT worth of BTC and 600K USDT worth of ETH, the remaining cross-chain quota for each bridge is 200K USDT worth of tokens.In short, compared to the previous version of the cross-chain mechanism, an important feature of the “Multi-chain Bridges” mechanism is that the staking assets can be shared among all cross-chain bridges, so the cross-chain quota is allocated on demand, and is reasonably and dynamically allocated to the wanBridges with higher demands for cross-chain transfer.2. BTC-Ethereum Direct Bridge enables direct cross-chain transfer of BTC from the Bitcoin blockchain directly to EthereumFor the previous cross-chain mechanism in Wanchain 5.0, all crosschain transfers supported by Wanchain were about transferring assets through Wanchain. In the Multi-chain Bridges, a direct bridge way for the cross-chain mechanism has come into play. The direct bridge supports asset transfer between two blockchains without the need of routing through Wanchain. This allows Wanchain to provide a technical mechanism to bridge Bitcoin, Ethereum, Polkadot, and EOS blockchains directly. For example, we build a direct bridge between Bitcoin and Ethereum for the direct cross-chain transfer of BTC:“BTC@Bitcoin->wanBTC@Ethereum”This is to transfer native Bitcoin from the Bitcoin blockchain to ERC-20 wanBTC on the Ethereum Blockchain. wanBTC can then be used for DeFi applications on the Ethereum blockchain that support the ERC-20 token format.The following picture shows Wanchain’s Multi-chain Bridges:In the vast ocean of cross-chain cryptocurrencies, there are floating islands, beautiful but isolated. Each island represents a chain. Due to the barrier of the ocean, those islands are isolated from each other. Reflected in the crypto world, each chain has their own different underlying frameworks, data structures, and APIs. Therefore, connecting one chain with another chain, especially for heterogeneous chains (those with significantly different technical infrastructure), is a major challenge.Wanchain aims to build a decentralized cross-chain infrastructure to connect the whole world since its inception. In the past few years, Wanchain has built cross-chain bridges, that is wanBridges, between different islands through continuous progress of cross-chain technology. Right now, all wanBridges are managed by a common Storeman Group (the number of Storeman Groups can be adjusted as needed). The Storeman Group is composed of 21 open and decentralized Storeman nodes (the number of Storeman nodes can be adjusted as well). With the scientific and reasonable security mechanisms and economic incentive models, the entire cross-chain system runs smoothly and brings the development and prosperity of the cross-chain ecosystem.We have added an extremely important wanBridge at this time, namely the Bitcoin-Ethereum direct bridge, so that BTC assets can be directly cross-chain transferred to Ethereum without routing via Wanchain.Based on the Bitcoin-Ethereum direct bridge, it is easier for users to transfer BTC directly from the Bitcoin network to Ethereum, and it also saves on cross-chain fees. But, how does it work?We might as well compare the workflow differences between the previous cross-chain mechanism and the new Multi-chain Bridges mechanism for the case of transferring BTC from the Bitcoin network to Ethereum.For the previous cross-chain mechanism, let’s assume that the Storeman Group between Bitcoin and Ethereum is called SG1, and the Storeman Group between Wanchain and Ethereum is called SG2. The workflow of transferring BTC from the Bitcoin blockchain to the Ethereum blockchain follows the steps below:Step1: The User initiates a BTC cross-chain transaction on the Bitcoin blockchain;Step2: SG1 locks the BTC on the Bitcoin blockchain after receiving this event and then mints the same amount of wanBTC for the user on Wanchain;Step3: The user initiates a wanBTC cross-chain transaction on the Wanchain blockchain;Step4: SG2 locks the wanBTC on Wanchain blockchain after receiving this event and then mints the same amount of wanBTC for the user on Ethereum.In the above procedure, a total number of 4 transactions are required, including 1 transaction on the Bitcoin blockchain, 2 transactions on Wanchain, and 1 transaction on Ethereum. Among these 4 transactions, the user is required to send 2 transactions — 1 transaction on the Bitcoin blockchain and 1 transaction on Wanchain.With the adoption of Multi-chain Bridges, the workflow becomes very simple. Let’s assume the combined Storeman Group called SG:Step1: The user initiates a BTC cross-chain transaction on the Bitcoin blockchain;Step2: SG locks BTC on the Bitcoin blockchain after receiving this event and then mints the same amount of wanBTC tokens for the user on EthereumIn the above procedure, a total number of 2 transactions are required, including 1 transaction on the Bitcoin blockchain and 1 transaction on Ethereum. Among the 2 transactions, the user is required to send only 1 transaction on the Bitcoin blockchain. For the user’s perspective, this simplifies the operation steps and saves cross-chain gas fees.Comparison Between the Old Cross-chain Mechanism and New Cross-chain MechanismCompared with the previous version of the cross-chain mechanism, the brand-new Universal Multi-chain Bridges With Shared Staking Assets has made major improvements and enhancements in regards to technology, ordinary users, and node operators. The following table shows the advantages of the new cross-chain mechanism.WanWallet Desktop, wanBridge Web Supports Direct Cross-chain Transactions of BTCIn terms of the cross-chain mechanism upgrade, the Wanchain development team has also made corresponding updates to our Wanchain Wallets, making enabling Multi-chain Bridges and the Bitcoin-Ethereum direct bridge function. After the next Storeman Group enters the working status on March 9th, users can directly cross-chain transfer their BTC from Bitcoin to Ethreum via WanWallet Desktop or wanBridge Web.Direct Cross-chain Transactions of BTC on the WanWalletLet’s take the WanWallet Desktop as an example (wanBridge Web is similar).Download the latest version of WanWallet Desktop V1.5.0.Open WanWallet Desktop, go to Cross Chain -> More Tokens, and check the star Bitcoin<->Ethereum. The direct cross-chain function for BTC to Ethereum is on.Go to Cross Chain -> BTC -> Bitcoin<->Ethereum. The BTC@Bitcoin->wanBTC@Ethereum window pops up. Here are the relevant parameters as follows:Balance: the balance of the BTC address from which you want to cross-chain transferStoreman Group: Select a Storeman Group. The active group is set by default. In general, you don’t need to choose.Capacity Left: The remaining cross-chain quota. Your cross-chain amount must be less than this amount.To (Ethereum): The recipient address on Ethereum that receives wanBTCEstimated Fee: The total amount of gas fees estimated in the cross-chain process (currently Storeman nodes do not charge cross-chain service fees)Amount: The amount of BTC that you want to cross-chain transferYou Will Receive: The amount of wanBTC that you will receive on EthereumAdvanced Options: The Gas Price can be set in the advanced options. In general, the default value is sufficient.For updates regarding the Multi-chain Bridge mechanism, please follow Wanchain’s official channels such as Medium and Twitter.

Wanchain And Benchmark Prot...

Wanchain And Benchmark Protocol Form A Strategic Partnership; wanTokens to Empower Benchmark MarketplaceStrategic Partnership Between Wanchain And BenchmarkIn February 2021, Wanchain and Benchmark Protocol formed a strategic partnership. On the basis of Wanchain’s innovative multi-chain bridges and Benchmark Protocol’s brand-new P2P lending platform Benchmark Marketplace, both parties will carry out in-depth and constructive cooperation on cross-chain DeFi applications empowered by cross-chain mechanism.In a pragmatic spirit, the two parties have reached an agreement to use “Benchmark Marketplace + wanTokens” as the entry point, allowing assets (wanBTC, wanETH, wanUSDT, wanDOT, WAN, etc.) on popular public chains to be integrated into Benchmark Marketplace, and those assets will be used for the lending types of tokens. By doing so, the Benchmark Marketplace, powered by cross-chain, will have richer lending tokens and better services as well as greater competitiveness. The two parties will put forward “Cross-chain + DeFi applications” step by step.Benchmark Marketplace: Lender-driven exchanges for Loan Offerings with More choices of Cross-chain AssetsThe Ethereum-based Benchmark Marketplace creates a lender-driven exchange for loan offerings. A lender creates a Marketplace contract through the Benchmark interface and defines the conditions (such as the lending out tokens, the loan ratio, etc) for their loan offering. A single loan offering can serve many different borrowers, as long as the created Marketplace contract holds enough tokens to provide the loan.The peer-to-peer lending services, the custom lending cryptocurrencies and interest rates, the any-time payoff mode, and the 100% fully decentralized lending mechanism constitute a remarkable highlight of the Benchmark Marketplace.Wanchain’s cross-chain mechanism will enrich the types of loanable cryptocurrencies on Benchmark Marketplace. Wantokens such as wanBTC, wanETH, wanUSDT, wanDOT, WAN will be integrated to the Marketplace step by step, so as to meet the needs of both borrowers and lenders.Wanchain Multi-chain Bridges Mechanism: Supports Cross-chain wanTokens, enabling unlimited possibilities for cross-chain DeFiWanchain empowers developers to build truly trustless, decentralized, cross-chain financial applications which connect with real world value. Wanchain has been building infrastructure to enable interoperable DeFi since 2017. In the past four year, the team has successfully cross-chain integrated with BTC, ETH, EOS, ERC20, etc.The Multi-chain Bridges mechanism is a novel cross-chain solution proposed by the Wanchain team to provide a high level of security and scalability. In this mechanism, all the direct bridges are run by a shared Storeman group with a shared staking deposit pool. This design reduces the complexity of the cross-chain process and ensures that all the cross-chain assets can freely “flow” among any chain. Moreover, it increases the maximum cross-chain capacity of a single bridge in security precondition.The partnership between Wanchain and Benchmark Protocol will achieve a seamless integration of wanBTC, wanETH, wanUSDT, wanDOT, WAN and other cross-chain assets on Benchmark Marketplace. Due to the perfect design of Wanchain’s multi-chain bridges mechanism, the security of cross-chain assets and the smooth experience of cross-chain assets lending are effectively guaranteed.About Benchmark ProtocolBenchmark Protocol is a Supply Elastic Collateral and Hedging Device, Driven by the Volatility Index. The protocol operates as a rules-based utility that dynamically adjusts supply based on the CBOE volatility index (VIX) and deviations from the target metric — equal to 1 Special Drawing Rights (SDR) unit. Employing the SDR creates a larger use case rather than exposure to just one currency; the application of this creates a larger user base and delineated exposure to markets around the world. The DeFi space needs a collateral utility that retains its efficacy and increases inherent, baseline liquidity during periods of high volatility.Benchmark is built on the Ethereum Blockchain. The MARK token is the native asset in the Benchmark network and provides only the utility value available to it through the Benchmark network.About WanchainWanchain empowers developers to build truly trustless, decentralized, cross-chain financial applications which connect with real world value. Wanchain has been building infrastructure to enable interoperable DeFi since 2017. Wanchain’s Storeman node powered cross-chain bridges eliminate the barriers between blockchains and allow you to use assets from multiple blockchains with differing technical architecture in your favorite DeFi applications. Multi-party computation, threshold secret sharing, and crypto-economic incentives power their solution for moving value between chains in a trustless, permissionless, and decentralized manner.Wanchain has employees globally with teams in China, the USA, and other team members around the world in Asia, Africa, and Europe.Wanchain And Benchmark Protocol Form A Strategic Partnership; wanTokens Empower Benchmark… was originally published in Wanchain on Medium, where people are continuing the conversation by highlighting and responding to this story.

To set up a node, users need to at least well prepare the following two things:You need to have enough WAN to stake to the Storeman node you created. Those WAN coins can be either totally contributed by yourself or partly from partners and delegators through the way of Partner In and Delegation. In short, the top 20 Storeman nodes with staking amount will finally enter to the Storeman Group.You have to buy the cloud service on AWS, Google Cloud, etc, and deploy your node on the cloud.For the detailed operations of how to set up a Storeman, please go to Wanchain 5.0 Mainnet Storeman Setup Guide.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

WanFarm Is Live! A New Jour...

WanFarm, an Ethereum-based yield farming dapp, is now live!WanFarm Link: farm.wanchain.orgWhat is WanFarmWanFarm is an Ethereum-based staking & farming DeFi application which is initiated by the Wanchain team.WanFarm aims to promote a series of wanTokens, such as wanBTC, wanDOT, wanXRP, wanEOS, wanTRX, etc., on mainstream public chains to be cross-chain integrated into Ethereum, which contributes sufficient liquidity to these AMM DEXes (e.g., UniSwap, SushiSwap) on Ethereum, and offers richer types of borrow & lend cryptocurrencies for lending dapps (e.g., Compound, Aave), so as to make Wanchain cross-chain assets form a scale effect in the huge and rich Ethereum ecosystem.At the same time, the increasing usage of cross-chain assets on Ethereum can in turn further accelerate the construction of cross-chain wanBridges. Driven by economic interests, Storeman nodes will continue to widen the wanBridges (that is, to ensure the quota of cross-chain assets by staking more collateral), and build up new cross-chain wanBridges (that is, to make more new assets to be cross-chain transferred to Ethereum by integrating new public chains with Ethereum). Therefore, Wanchain’s cross-chain mechanism and DeFi applications will develop hand in hand and complement each other.Key InformationLaunch Time: February 9th, 2021WAN Rewards Begin: At the Block Height 11,837,258 on Ethereum (around 4:00 p.m. UTC+8, February 12, 2021)Staking Preparation Time: February 10th — February 11thWebsite: farm.wanchain.orgFarming Mode: WanFarm + SushiSwap dual farming mode.

Wanchain — “Universal Multi...

Wanchain — “Universal Multi-chain Bridges with Shared Staking Assets” Is Live On Testnet!On February 9, 2021, after three-months of development, the Wanchain team has launched a brand-new cross-chain mechanism:The “Universal Multi-chain Bridges with Shared Staking Assets” is now live on Wanchain testnetThe direct cross-chain bridge BTC-Ethereum is integrated into WanWallet Desktop (for testnet use)The “Universal Multi-chain Bridges with Shared Staking Assets” is short for “Multi-chain Bridges”. We invite everyone from the community to participate in testing this brand-new cross-chain mechanism, and leave some feedback and suggestions on the new mechanism and the supporting products.Here is the Download link for the WanWallet Beta version. It supports Windows, Mac and Linux.Highlighted Features of “Multi-chain Bridges”Shared Staking AssetsThe Multi-chain Bridges mechanism is a novel cross-chain solution proposed by the Wanchain team to provide a high level of security and scalability. In this mechanism, all the direct bridges are run by a shared Storeman group with a shared staking deposit pool. This design reduces the complexity of the cross-chain process and ensures that all the cross-chain assets can freely “flow” among any chain. Moreover, it increases the maximum cross-chain capacity of a single bridge in security precondition.Direct Cross-chain Bridge: BTC-EthereumIn the Multi-chain Bridges mechanism, only two steps are needed to transfer BTC to Ethereum: First, the user sends BTC to the locked account via the cross-chain transfer interface of WanWallet; Second, the Storeman group identifies the transaction and mints the same amount of wanBTC on Ethereum. If the cross-chain demand of transferring BTC to Ethereum grows rapidly, the cross-chain deposit will shift towards BTC-Ethereum direct bridge automatically, which prevents cross-chain failures due to insufficient deposit and ensures the fluency of the cross-chain process.Comparison Between Old Cross-chain Mechanism and New Cross-chain MechanismDownload WanWallet to Test Multi-chain BridgesIn this test, WanWallet Desktop beta version supports the multi-chain bridges mechanism and the BTC-Ethereum direct cross-chain bridge.WanWallet Desktop Beta download:Release 1.5.0-beta · wanchain/wan-wallet-desktopApply for Testnet coins:BTC testnet coin: https://testnet-faucet.mempool.co/WAN testnet coin: https://wanchain-faucet.vercel.app/ETH testnet coin: https://faucet.rinkeby.io/Open WanWallet Desktop, go to Cross Chain -> More Tokens, and check the star Bitcoin<->Ethereum. The direct cross-chain function for BTC to Ethereum is on.Go to Cross Chain -> BTC -> Bitcoin<->Ethereum. The BTC@Bitcoin->wanBTC@Ethereum window pops up. Here are the relevant parameters as follows:Balance: the balance of the BTC address which you want to cross-chain transferStoreman Group: Select a Storeman Group. The active group is set by default. In general, you don’t need to choose.Capacity Left: The remaining cross-chain quota. Your cross-chain amount must be less than this amount.To (Ethereum): The recipient address on Ethereum that receives wanBTCEstimated Fee: The total amount of gas fees estimated in the cross-chain process (currently Storeman nodes do not charge cross-chain service fees)Amount: The amount of BTC that you want to cross-chain transferYou Will Receive: The amount of BTC that you will receive on EthereumAdvanced Options: The Gas Price can be set in the advanced options. In general, the default value is sufficient.We invite everyone from the community to participate in testing the new version of the WanWallet Desktop. If you have any feedback, let us know over on our telegram chat! https://t.me/WanchainCHATOutlook On MarchAccording to Wanchain 2021 roadmap, we plan to upgrade the original cross-chain mechanism to the Universal Multi-chain Bridges with Shared Staking Assets on Wanchain mainnet as well as the go-live functions of the BTC-Ethereum direct cross-chain bridge and the XRP-Ethereum direct cross-chain bridge.For more cross-chain integration of assets (such as DOT, TRX, etc.) on public chain , we are keeping on studying and developing step by step.

Cointelegraph China Intervi...

Cointelegraph China Interviews Jack Lu — “Cross-chain DeFi” Is Trending in 2021The Image is from Cointelegraph ChinaHere is the original Chinese version of the Cointelegraph interview2020 was a year full of opportunities and challenges for the global economy. But for the crypto world, blockchain and cryptocurrencies fully proved its value in 2020.In early January, 2021, the crypto world began a new journey. Cointelegraph China interviewed representatives from well-known token funds, exchanges, mining companies, public chains, DeFi projects, crypto KOLs, etc., and listened to their judgments on the trend in 2021, what aspects attract them most, and what hopes and goals do they have in 2021?Here is the interview contents between Cointelegraph China and Jack Lu.What is the crypto keyword in 2021?A: Cross-chain DeFi2. What is the message you’d like to send across the crypto industry in 2021?A: Wanchain’s innovative cross-chain mechanism will allow different chains and applications enjoy the DeFi feast. Every person will become a witness and creator of the Internet of Value.3. Will the current trend in the blockchain industry keep going? What trends will we see in 2021 that we didn’t experience in 2020?A: In 2020, we encountered the Covid-19 pandemic, and also experienced an unprecedented sharp drop on March 12th, 2020. But with the explosion of DeFi, one of the leading characters in blockchain industry in 2020, we can say that DeFi has become the most important trend in 2020, and with the development of DeFi, the whole crypto world has ushered in a long-lost market boom. I believe that the blockchain industry will further heat up the trend in 2021. Capital, talents, and resources will further gather in the industry. Blockchain technology and applications will accelerate their iteration. The periodic bull market will come to the crypto world.In the field of public chains, with the great success of DeFi applications on single public chains in 2020, the cross-chain DeFi will surely take over the “relay baton” of single chain DeFi in 2021, making the cross-chain DeFi dapps boom in multiple public chains. And I believe that Wanchain will be one of the leading roles for this “relay”.In the consortium chain field, more and more industries will be penetrated by blockchain technology in 2021. Cross-chain technology will usher in demand growth, and the blockchain will play an increasingly important role in the digital economy and the economic society.4. What is the most attractive point for you in the blockchain world? what is your goal or hope in 2021?A: The development of the blockchain world is like turbulent ocean waves, one after another, both thrilling and beautiful. This attracts me most.In the past few years, the Wanchain team has been concentrating on the development and innovation of cross-chain infrastructure. We have fulfilled the milestones promised in the white paper. Looking forward to 2021, we hope that more and more global users will come to the Wanchain community, that the Wanchain cross-chain mechanism can bring real value to the institutional users and individual users, and that the entire industry can truly appreciate the great significance of all chains connected.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

The Third Storeman Group Be...

The Third Storeman Group Begins February 1st, 2021 — Don’t Forget to Register Your Node!The Storeman Group has been running for more than two months since the first group open on November 21st, 2020. According to the cycle parameters, the third Storeman Group will begin its selection on February 1st, 2021.Make certain to prepare your node if you want to participate in the third group, or to register to withdraw if you are a current Storeman node and wish to withdraw.Read more below for details.DetailsSelection Time: 4:00 AM UTC, February 1st, 2021–4:00 AM UTC, February 7th, 2021Negotiating Time: 4:00 AM UTC, February 7th, 2021–2:00 AM UTC, February 9th, 2021Working Time: 4:00 AM UTC, February 9th, 2021–4:00 AM UTC, March 9th, 2021Amount of Storeman Nodes: 21 (including one Foundation node)Threshold of Storeman Node: 10,000 WAN, the Partner In mode is supportedRules To Win The Selection: The top 20 Storeman nodes with staking amount will enter Storeman GroupDelegation Fee Rate: 10%Deposit Rate: 150%Delegation Ratio: 1:5wanBridge: The Storeman Group at this cycle is applicable to Wanchain-Ethereum wanBridgeNote: If you are currently operating a Storeman node and do not wish to participate in the second group, you must register to exit before January 31st, 2021 — in order to withdraw when the current period ends. But we highly recommended that if you do not wish to participate in the second group, you can withdraw as early as you can. If you withdraw, staked funds will be returned to your wallet on February 10th, 2021. Rewards will be issued daily as usual during the withdrawing period.Nodes who do not register to exit before the end of the current period WILL be included in the selection process for the next periodHow To Create A Storeman NodeIn general, the rewards rate of running a Storeman Node is about 50% higher than the rewards rate of being a delegator. To set up a node, users need to at least well prepare the following two things:You need to have enough WAN to stake to the Storeman node you created. Those WAN coins can be either totally contributed by yourself or partly from partners and delegators through the way of Partner In and Delegation. In short, the top 20 Storeman nodes with staking amount will finally enter to the Storeman Group.You have to buy the cloud service on AWS, Google Cloud or Ali Cloud, etc, and deploy your node on the cloud.For the detailed operations of how to set up a Storeman, please go to Wanchain 5.0 Mainnet Storeman Setup Guide.Increasing Amount of Staking Assets & Converted Assets13.45 Million WAN Staked!The total staking amount of current Storeman Group has increased significantly, from 2.2 million WAN on November 15th, 2020 to 13.45 million WAN as of January 27th, 2021.Over $3.25 million in Cross-chain AssetsThe value of cross-chain assets including wanBTC, wanETH, wanEOS, wanUSDT, wanUSDC, wanUNI, wanLINK, which now exceeds 3.25 million USD.Besides, the Ethereum-based DeFi application WanFarm will soon start its staking & mining. Stay tuned.A Major Upgrade For Wanchain’s Cross-chain Mechanism in Q1, 2021For Wanchain 5.0, there is a one-to-one correspondence between a wanBridge and a Storeman Group. Therefore, to connect any two public chains, at least one Storeman Group must be created between the two. Under this mechanism, if a Storeman node wants to participate in multiple wanBridges of connecting different public chains, the node operator must run multiple Storeman nodes in different Storeman Groups. Obviously, this situation increases the difficulty of operation for node operators. The deposit funds among different Storeman Groups are independent and cannot share the cross-chain quotas with each other. So, the utilization rate of the deposits is low, which results in the intensive economic bandwidth of busy wanBridges and wastes economic bandwidth of leisure wanBridges. Theoretically, this mechanism has a small security risk of collusion among Storeman nodes.For the reasons above, considering the efficient utilization of resources, the improvement of cross-chain security and the optimization of user convenience, the Wanchain cross-chain mechanism will undergo one more major upgrading on the basis of 5.0. It is expected that the upgraded Storeman Group mechanism will be launched in Q1 2021.Currently, the new cross-chain mechanism is being developed and tested in an orderly manner.At that time, a Storeman Group will uniformly manage all wanBridges which connect two different public chains, and the staking deposits will also serve as the common deposit for all wanBridges in the entire cross-chain network.For more details on the new generation of Wanchain’s cross-chain mechanism, please see the article Universal Multichain Bridges with Shared Staking Assets written by VP of Engineering, Dr. Zhang Weijia.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

The Wanchain 2021 Roadmap!

2020 has been a major step forward for Wanchain in realizing the vision initially set out in our whitepaper several years ago. We have successfully launched our decentralized, permissionless, and community controlled cross-chain wanBridges with Wanchain 5.0, and are continuing to iterate and improve our cross-chain technology. Our wanBridges are a major technical achievement, and with them completed, in 2021 we will shift our focus from low-level infrastructure building to ecosystem expansion. In 2021 we will focus on expanding the number of chains connected by our decentralized cross-chain technology, and on fostering the development of applications which benefit from using our tech. We will integrate several new public chains and many new assets. Another major focus will be on the development of Wanchain’s developer community.New Asset & Blockchain IntegrationsIntegration of XRPIntegration of DOTIntegration of other chainsAdditional ERC20 tokensWe’ve had our eyes on the Polkadot ecosystem for quite some time, and they will form big part of strategy moving forward. We plan to integrate Polkadot and the DOT token as well as other Substrate based tokens. Of course we will continue to integrate other new ERC20 tokens in order to make them available for usage in the Wanchain DeFi ecosystem which has seen major growth in recent months including WanSwap and WanLend, as well as several other major products under development such as WanFarm and other DeFi applications.Infrastructure UpdatesUpgrade of wanBridges to increase node operator profitability and make new chain integration more efficientUpgrade economic model of wanLendThe current wanBridge model allows for assets to securely and cheaply be transferred between different blockchains. It’s a milestone for Wanchain and for the blockchain industry in general in terms of its technological achievements. Despite this, there is still room for improvement, particularly in terms of the scalability of the model. The current model requires that a new Storeman Node group be established for every new pair of blockchains to be connected. From a security model this is fine, but in terms of economic scalability, it’s not acceptable for a model which needs to support multiple chains. The model would require an ever growing number of Storeman Node groups in order to connect all blockchains. Moreover, since the collateral in each Storeman Group can only be used for transfers between the two chains connected by that group, it does not allow for efficient use of collateral across all chains.In 2021, we will introduce a new wanBridge model which allows for a SINGLE Storeman Group to connect MULTIPLE blockchains and use their collateral to power transactions between ALL blockchains connected by the group. This allows for much more efficient use of collateral and for wanBridge technology to scaleably connect essentially any number of different blockchains.Power Up With Liquidity MiningwanFarm launchMining incentives for cross-chain liquidityIn the world of DeFi, Liquidity is King, which is why we’re super excited to be welcoming wanFarm to our WAN Family. wanFarm is a liquidity farming application which will allow users to lock up liquidity tokens such as Uniswap’s UNI-V2 and others in order to earn rewards for providing liquidity. wanFarm will be used strategically to drive liquidity to the parts of the Wanchain DeFi ecosystem where it is needed most. The increases in liquidity will in turn increase the functionality of applications in Wanchain’s ecosystem, which will in turn lead to more users. More users will then in turn lead to higher rewards for liquidity providers, which will establish a virtuous cycle which then leads to increased liquidity.Showing Our Devs Some LoveIntroduction of new dev community grantsNew developer tools (sdk & api) to make it easy to integrate wanTokensPromotion of wanTokens for use in cross-chain DeFiIt has been a great year for the Wanchain developer community. Community devs such as ‘Morpheus’, ‘CryptoFennec’, ‘Neo’, and many others have made amazing contributions to Wanchain projects such as WanSwap and WanLend, and some have even developed awesome Wanchain based projects totally on their own — such as CryptoFennec’s awesome WanStakeInsight Wanchain explorer. In 2021, we intend to kick our developer community into overdrive with an all new set of developer grants which will be available to be paid to any developers who contribute to the Wanchain ecosystem. We will soon publish more information about how developers can get paid to build on Wanchain, so make sure to stay tuned to our Telegram and Twitter! And of course, we ALWAYS welcome any developer who has an idea to pitch directly to us. Just get in touch with one of the admins on our official Telegram chat and they will help connect you with the Wanchain dev team.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Recent Crosschain Q&A from ...

Q1. How crosschained BTC to wanBTC is realized?A: Please read this article for general idea:https://www.explorewanchain.org/#/technology/cross-chainCodes on Githhub Repo:https://github.com/wanchain/wanchain-crosschain-contracts/tree/btc_wan_crossQ2. About Storeman GroupThreshold + MPC method to manage cross-chain assets, is it managed through multiple groups? How many groups are there, and how to manage different groups?A: The previous design was that each cross-chain bridge (two chains or called one pair) use one storeman group with 21 nodes. The latest research update is that cross-chain bridges will share a combined Storeman group to enhance the utilization and security of collaterals. The number of nodes in this combined group can be expanded.More details please refer to this article:https://medium.com/wanchain-foundation/understanding-wanchain-two-way-bridge-and-direct-bridge-7f6088617734Q3. Does each group involve 21 nodes, and requires at least 16 signatures, and generates one address?A: It is now a Storeman group of 21 nodes, which can be expanded. The required threshold signature is 15, and aone address is generated.Q4. When one Storeman group is switching to a new group, do other groups need to re-generate key fragments?A: Different groups are independent. Every time when a new Storeman group election is selected to replace the old one, it is necessary to re-produce the key fragments.Q5. If a Storeman node commits malicious behavior and needs to be slashed and expelled, how to deal with it? When it comes to adding or expelling nodes, does the protocol itself support dynamic adding and removing of a node?A: When we started the project back in 2017, the theoretical reference was: “Robust Threshold DSS Signatures” and after 3 years of evolution, now we implemented using this reference: “Fast Multiparty Threshold ECDSA with Fast Trustless Setup”. The procedure for dealing with malicious behavior is that: the node’s own collaterals (currently is his staked WAN coins) will be slashed by a percentage when the malicious action occurs for the first time; and after that, if such malicious actions are committed again, the collaterals deduction will continue until all staked WAN coins are finished. After that, the MPC will not use any data provided by this node. We do not support dynamic node changes during the current group work cycle. The current design is when a new elections will be held on the 1st-7th of each calendar month, the balances of cross-chain assets of the previous group will be handed over to the newly selected group on 8th-9th, and new cycle of work will begin on the 10th. Adding or removing nodes will happen that the moment.P.S. In addition, our research team has been studying how to achieve dynamic changes of nodes. It is also hoped that it will be an quite important milestone for the next technological implementation.Q6. When signing the execution of cross-chain assets, is it necessary for at least 16 nodes to be online at the same time to sign and how many rounds of signing? How was this interaction cost considered?A: Firstly, our protocol needs 15 nodes are online to sign, not 16. Interactions between these nodes: for BTC-WAN, it needs 3 rounds; and for ETH-WAN it requires 2 rounds. The cost has been verified and approved by engineering implementation that it fully meets cross-chain requirements (speed, cost); and it can be expanded to large-scale node adoptions easily (scalability).Q7. I think Storeman group’s participation in the cross-chain execution is a very essential mechanism. Is the collateralized funds valued in fiat currency? How can the Oracle ensure stable execution of different prices and will not make permission switching errors? Where does the rewards to Storeman nodes come from?A: The collaterals now are WAN coins and WAN is valued by its fiat USD price coming from exchanges. When executing other assets such as ETH and BTC, the protocol follows the 150% over-collateralization rule currently. Storeman group’s WAN coins are priced in USD value to make sure the collaterals are 150% more than crosschain assets.When user transfer WAN to Ethereum for example, collaterals, which are the WAN coins are priced based on a 1:1 matching amount, regardless of fiat factor.The Oracle in Storeman is completely decentralized and adopts the design idea of “Signature is Consensus, SOC”. The decentralized design does not involve the issue of any permission switching. In addition, the rewards for Storeman now is from reserved WAN coins by the Foundation as illustrated clearly in its whitepaper. And we expect that with more adoptions of crosschain operations in the near future, the service fee for crosschain operation will be charged for each transaction, and these rewards will 100% go to Storeman nodes.Q8. Cross-chain assets need to map ‘Issued ‘tokens. Whether the number of mapping issued tokens is correct is crucial. What is the purpose of adding HLTC to cross-chain?A: My understand that ‘issue’ here means mint, which is exactly in accordance with the one-to-one mapping between locked and minted numbers. This is how it works: once the cross-chain transaction is proposed by the user, after the Storeman group will construct one transaction, and the request as well as the number of minted tokens are passed to each node of the group for verification and signing. Nodes will only sign if the number of minted token is exactly the same as the number of locked amount. Therefore, as long as the cross-chain process is successful, the number of minted token must be commonly agreed in the Storeman group, that is, the idea of “Signature is Consensus, SOC” mentioned above. The old version of the cross-chain mechanism adopts HTLC to ensure the atomic swap; but after the new cross-chain mechanism is updated, the combined open Storeman design no longer needs HTLC to ensure the atomic swap. Thus HTLC has been removed from the protocol.More to read about other details of Wanchain’s crosschain design and implementation, please refer to these articles:Comparative Analysis of wanBTC with tBTC https://medium.com/wanchain-foundation/comparative-analysis-of-wanbtc-with-tbtc-620b87bb9846Understanding Wanchain Two-Way Bridge and Direct Bridge for crosschain operations https://medium.com/wanchain-foundation/understanding-wanchain-two-way-bridge-and-direct-bridge-7f6088617734?source=collection_home---4------1-----------------------Universal Multichain Bridges with Shared Staking Assets https://medium.com/wanchain-foundation/universal-multichain-bridges-with-shared-staking-assets-e2a50669f016About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Major Upgrade of Wanchain-B...

What is Dark Forest?Dark Forest was first developed by the team of the Ethereum community and released to the Ethereum blockchain (Original Dark Forest URL: https://zkga.me/). It became more and more popular among Ethereum players. What is more noteworthy is that this game is also loved and appreciated by many influential users such as Ethereum founder Vitalik Buterin, Figma CEO Dylan Field, etc.With the characteristics of open source code, continued popularity, trendy contents, coupled with the high efficiency and low gas fee of the Ethereum dapp to be migrated to Wanchain, Ethereum-based Dark Forest was re-developed and re-deployed on the Wanchain blockchain by Wanchain developers in early December last year. This is the game about universe exploration and interstellar conquest. It is also the first NFT Dapp in the Wanchain ecosystem. Here, we are particularly grateful to the Ethereum-based Dark Forest team for all their efforts on this game, and also thank the developers from Wanchain for introducing such a high-quality Dapp from Ethereum to Wanchain, making great contribution to the prosperity of the Wanchain ecosystem.NFT (non-fungible token) is a token with uniqueness and inseparability. The well-known CryptoKitty tokens are typical NFTs, and the tokenized collectibles and game props are very suitable for converting themselves to NFTs.In Dark Forest, artifacts hidden on different planets have different values ​​due to their different types and scarcity. Each planet conquered and developed by players has different coordinates and levels, attributes, so the power of planet is also different with each other. All of these resources constitute the rich NFT assets in the Dark Forest game. In the future, players can even take their planetary assets to the NFT trading market for trading, just like trading game props between players in traditional games.Wanchain-based Dark Forest: http://darkforest-v5.wandevs.org/Since the release of Wanchain 5.0 in Q4 last year, the Wanchain ecosystem has attracted a large number of developers and enthusiasts. A series of ecological applications have been released, including WanLend, WanSwap, FinnNexus Options, Red Packet, BittlyDEX, Wandora Box, Jack’s Pot , Dark Forest, etc.​What’s New for Dark ForestAccording to the major upgrade of original Dark Forest on Ethereum, Wanchain developers have also upgraded the Wanchain-based Dark Forest.Here are the new features:Added an experimental plugin systemSeek artifact NFTs by exploring the universePerformance improvementsIt is worth noting that the players’ data and records in the old version of Dark Forest cannot be inherited to the new version of Dark Forest. Players must re-create the game account to start a new journey.Advantages of Developing Dapps on WanchainCompared with developing Dapps on other public chains, developing dapps on Wanchain has many advantages. The advantages can be summarized as the following two pointsDual Dapp: One dapp to be deployed on both chainsWith the existing Dapps on Ethereum, we can easily deploy a set of the same Dapps on Wanchain to facilitate users to participate in the dapp. At the same time, with the help of Wanchain’s wanBridge cross-chain mechanism, these Dual Dapps’ internal assets can be freely transferred between the two chains, thereby greatly expanding the application scenarios and audiences.Solving the pain points of high gas fees on EthereumAt present, the gas fees on Ethereum has been reduced compared to the previous period, but the gas fees of a few dollars or even a dozen dollars for a single transaction with smart contract are still barriers for common users. In the face of helpless users and project parties, deploying Dapps on Wanchain can effectively solve this pain point.The project team can deploy a DeFi application on Wanchain that is exactly the same as that on Ethereum, allowing users to fully enjoy the functions on Wanchain but a completely different experience: extremely low Gas fees and extremely fast transaction speed. In addition, through Wanchain’s cross-chain mechanism, users can cross-chain transfer back their DeFi assets from Wanchain to Ethereum.Of course, the Ethereum-based Dark Forest team now adopts layer 2 network mechanism to solve the expensive gas issue.How to Play the ‘Dark Forest’​Wanchain-based Dark Forest: http://darkforest-v5.wandevs.org/Developed by: Wanchain developersAudit by: Wanchain dev teamNote: The game is derived from the original Ethereum-based Dark Forest, so the Space Masters information has not been cleared.Create An AccountOpen the Dark Forest website in Google Chrome. Click “Enter” to start the game (Please note that other browsers do not support it at present.)Then type “n” to create a new account. Copy the account address and save it as a file. Meanwhile, transfer a small amount of WAN to this address for gas fees. (2WAN is enough for your to play the game). Press any key to continue.After waiting for the game to download data and initialize successfully, press Enter to start from your home star. If there is 0 WAN in the address, an error will pop up to tell you that the balance is insufficient.When entering the game again next time, you can directly type “a” to log in an existing account.Explore in the universe​Explore in the universe, occupy planets, and collect resources.Resources are divided into two types: ‘Energy’ and ‘Silver’.Energy is used for resource transportation and planet occupation, and silver mines are used for planet upgrade.Level 0 planets cannot be upgraded or stored silver mines.Each planet can automatically increase its energy until it reaches the energy limit.Only some special planets can produce silver mines.(As shown in the picture below: the lightning icon is the energy, and the ZK icon is the silver mine)​Each planet has a natural level. Level 0 is the lowest and cannot be upgraded. Planets level 1 and above can be upgraded through using silver mines.Click the planet, and click the details button to view the detailed information of that planet.​​Detailed information is shown below:The UP arrow in the bottom indicates that this planet can be upgraded.After clicking, you can see that there are 3 upgrade directions: defense, range, and speed. (As shown below)​When the number of silver mines is reached, you can upgrade.Multiple players can attack each other’s planet.It takes extra energy to occupy a planet with wild monsters.​The dotted circle displayed after the planet is selected represents the distance that the current energy can reach. The longer distance, the more energy is consumed. (As shown below)After selecting a planet, click the ‘Send Resources’ button to start carrying resources to other planets. Below, you can use the lightning icon or the up and down arrows to select the amount of energy as well as the silver mines carried by that trip.​Planets with energy shields or wild monsters need extra energy to occupy. You can use the energy of multiple planets to consume the energy shield little by little until the energy is zero and occupy it.You can click to buy ‘HAT’ , and use $WAN coins to purchase and upgrade the hats. Hats have different patterns.Tap the ‘+-’ symbol in the upper left corner of the screen to quickly zoom in and out of the map.Click the settings button in the upper left corner to export the private key, coordinates, and map. These three elements are essential to resume this game.The map is continuously expanded and explored through the hash computation.Exploring the map consumes more CPU, you can click the pause button to stop and continue exploring at any time.​You can bind your Twitter account in the upper left corner and give yourself a customized account name.Each planet can be created as a Non-fungible token (NFT). The red circled part represents this NFT’s unique ID. In the future, such NFT tokens can be traded among users through another NFT trading platform by using WAN coins.Explore the universe artifacts — NFT assetsAs you explore the universe, you will find artifacts from the planets. If the player finds that there are artifacts hidden on a planet, they can obtain them. The artifacts will improve the attributes of the planet, similar to the traditional game for the roles to wear different game props.The universe artifacts are classified according to categories and rarity. The artifacts obtained on this planet can also be transferred to other planets.Finally, have fun with Dark Forest and create your unique NFTs!About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Understanding Wanchain Two-...

Understanding Wanchain Two-Way Bridge and Direct Bridge for crosschain operationsWeijia Zhang, WanchainWanchain is a blockchain project that focuses on building bridges to connect with public or private, homogeneous or heterogeneous, blockchains. From Wanchain 2.0 to Wanchain 5.0, Wanchain has connected with various blockchains such as Ethereum, Bitcoin, and EOS. For 5.0, Wanchain releases two-way bridge to connect with Ethereum blockchain through the Open Storeman mechanism. This has achieved the technical framework as laid out in the Wanchain whitepaper. Going beyond that, Wanchain has been working on direct bridge that will connect two public blockchains without the need of routing through a hub blockchain as shown in the following architectural diagram extended from Wanchain’s original whitepaper.Wanchain expands crosschain architecture to two way bridge and direct bridgeIn this article, we describe in details some basic concepts, features, and processes for two-way bridge and direct bridge.Two-Way Crosschain BridgeNot all bridges are the same. A bridge in the context of this article is a platform that can transfer assets from one blockchain to another blockchain. There are three elements that are important to describe a crosschain bridge: a) who provides the bridge; b) what assets are transferred in a bridge; c) on what blockchain the assets reside. As crosschain technology and applications are still at an early stage and there are only a few applications that provide solutions for bridging assets in different blockchains, there are many conceptions that need to be clarified to better understand crosschain bridges. For example, we used the word “wrapped ether” to represent ether in its ERC20 format and “wrapped BTC” for BTC in its ERC20 format. This is very inaccurate as the first one is on its native chain and the other is crossed from another blockchain. It is very important to differentiate an asset crossed from another blockchain as the value of this asset depends on the security of the existing chain, the source chain, and the bridges that connect the two.We would also think intuitively that all bridges are two-way bridges, as assets transferred from blockchain A to blockchain B should be able to be redeemed back to its original chain. However, if we look at all the solutions that are provided for crosschain bridges, the asset transfers are only unidirectional as almost all solutions are to bring assets to Ethereum blockchain. It is very rare for Ether to be transferred to other blockchains.To better understand a two-way bridge, it is important to know that assets in crosschain system can have two distinct forms: one is native assets that are generated from its source blockchain, and another is transformed assets that are minted after locking assets in its parent blockchain. For example, in Ethereum blockchain, Ether and most of the ERC20 tokens, are native assets, while wrapped ERC20 tokens, such as wBTC and wanBTC, are transformed assets. Transformed assets are created through crosschain bridges, most of them centralized. Native assets can exist standalone in its source blockchain, while transformed assets cannot exist independent of its locked native assets. Here, we use the term “transformed asset” to mean an asset that is locked in its source chain and minted in the target chain. Several other terms such as “derived asset,” “wrapped asset,” or “foreign asset” can also be used to describe this important conception in the crosschain bridge.Due to different blockchains having different consensus, cryptography, and smart contract support, not all crosschain asset-transfers are supported. For example, it is easy to transform a BTC asset from bitcoin blockchain to Ethereum blockchain, but it is not easy to transfer an Ether from Ethereum blockchain to bitcoin blockchain due to lack of smart contract support on Ethereum blockchain. Hence, we call this a one-way bridge. A one-way bridge is a bridge that allows a user to transfer a native asset one-directionally from a source blockchain to a transformed asset in a target blockchain and redeem the asset back to its source form. A one-way bridge does not support transferring a native asset in a target blockchain to another asset in source blockchain. This is currently the case for most of the bridges that support asset transfer.Before Wanchain 5.0, all Wanchain bridges were one-way bridges, as Wanchain could transfer native assets in Bitcoin, Ethereum, and EOS blockchain to Wanchain, but did not support transferring native Wancoin from Wanchain to external blockchains. Wanchain 5.0 expands this feature to support two-way bridges, meaning that Wancoin assets can be transferred to Ethereum blockchain, and Ethereum assets can be transferred to Wanchain blockchain. This allows Wanchain assets to participate in decentralized applications in Ethreum and vice-versa, allowing Ethereum native assets to be transferred to Wanchain for dapps that are faster and with lower gas fees.Wanchain <-> Ethereum two way bridge supported assetsWanchain 5.0 supports two-way bridge asset transfer for Wanchain and Ethereum blockchain. The following table shows the supported asset types. To better understand the table, we briefly mention the notation used in the Wanchain crosschain representation. This set of notations is also in discussion in the Enterprise Ethereum Alliance (EEA) Crosschain Interoperability Task Force as a candidate to describe crosschain assets.In the crosschain assets representation, three factors need to be described: the provider of the token, the taken symbol, and the blockchain in which the asset resides. A crosschain asset is represented as: [provider]TOKENSYMBOL@ChainnameHere, TOKENSYMBOL is the conventional token symbol, such as ETH for Ether, BTC for Bitcoin Classic, WAN for Wancoin, etc. “Provider” represents a project team name or a mechanism that creates the token. The “provider” can be omitted if it is unique and the same as the token symbol. “@Blockchain” is to represent the assets’ blockchain.In this table, WAN@Wanchain means WAN token in Wanchain blockchain. This is a native asset of Wanchain and is what we normally call “WAN.” WAN@Ethereum is a transformed asset of WAN on Ethereum blockchain. WAN@Ethereum is in ERC20 format. Similarly, ETH@Ethereum is the native asset of Ether in Ethereum blockchain. And wanETH@Wanchain represents transformed ETH onto Wanchain by Wanchain bridge. If in the future, another project team called me2 creates another bridge to transfer ETH to Wanchain, then the transformed asset would be named as me2ETH@Wanchain.From the supported asset transfer table above, it is shown that native assets of WAN@Wanchain can be transferred to asset of WAN@Ethereum on Ethereum blockchain. Also, native assets of ETH on Ethereum blockchain can be transferred to wanETH@Wanchain on Wanchain blockchain. Hence, we call the bridge that enables mutual transfer of native assets between two blockchains as “Two-Way Bridge.”Two-way bridge asset transfer with WanwalletUsing two-way bridge to transfer assets crosschain through Wanwallet is very straightforward. The Wanwallet provides a multi-chain wallet that stores assets for both Ethereum blockchains. User just need to pick a source asset from the account list, choose the target chain, choose the bridge provider (open storeman), choose or enter the target account address, enter the amount to transfer, and then confirm to start a transfer.From the above description of scenarios, it is clear that with Wanchain 5.0, assets can transferred from Wanchain to Ethereum blockchains back and forth with a simple user experience and work flow.Wanchain Direct BridgeUp to Wanchain 5.0, all crosschain transfers supported by Wanchain were about transferring assets through Wanchain. A direct bridge platform is to expand the Wanchain platform to support asset transfer between two blockchains without the need of routing through Wanchain. This will allow Wanchain to provide a technical mechanism to bridge Bitcoin, Ethereum, Polkadot, and EOS blockchains directly. Using similar crosschain asset transfer syntax, we should support the following crosschain transfer use cases for Ethereum and Bitcoin direct bridge:BTC@Bitcoin->wanBTC@EthereumThis is to transfer native Bitcoin from bitcoin blockchain to wanBTC ERC20 format token in Ethereum Blockchain. wanBTC can then be used for DeFi applications in Ethereum blockchain that supports ERC20 format tokens.wanBTC@Ethereum->BTC@BitcoinThis is to transfer the transformed BTC in Ethereum blockchain back to its native BTC in Bitcoin blockchain.Other questions about direct and two-way bridgesWill direct bridge still leverage Wanchain blockchain?Wanchain will not be involved in the transaction data flow in a direct bridge. However, the staking of bridge assets will be done on Wanchain. The security of a bridge is guaranteed by staking assets onto Wanchain through smart contracts. The registration for staking and delegation will remain the same. There is a possibility that multiple assets can be used as collaterals for staking.How are crosschain transaction fee calculated?For direct bridge, there are two crosschain fees, one is the transaction fee on the native blockchain: this fee is paid in its native gas fee. The other one is crosschain fee: this can be decided by the community and might be waived initially.Are two-way bridge and direct bridge mutually exclusive?No. A direct bridge can be a one-way direct bridge or two-way direct bridge. Two-way bridge deals with asset transfer directions for NATIVE assets, rather than transformed assets. If a bridge connects blockchain A and B, and native assets can be transferred from blockchain A to B as well as from blockchain B to A, this bridge is called a two-way bridge. Whereas, if a native asset can only be transferred from blockchain A to B, but not the other way, then this bridge is called one-way bridge. Note that when we define one-way or two-way bridge, we only take native asset transfer into consideration, because transformed assets can always be redeemed back to its native asset form.Aren’t all bridges two-way bridges? Otherwise, how can we redeem the assets back to its source chain?Not all assets are the same. Here, we introduce the concept of native assets and transformed assets. For a crosschain transfer, the asset in the source chain is locked, rather than destroyed. The value of the transferred assets still reside in the locked assets in the source chain. One-way bridge means that a native asset in blockchain A can be transferred to transformed asset in blockchain B, while the transfer in the other direction is not allowed. For example, several projects provide transferring Bitcoin to Ethereum blockchain, but no project provides transferring Ether to Bitcoin blockchain. So all bridges between Bitcoin and Ethereum blockchain are one-way bridge only so far. A two-way bridge means that native assets can transfer from blockchain A to B and vice versa from blockchain B to A.FeedbackWe are collecting feedback for direct bridge.

WanLend Operating Instructions

WanLend is a decentralized financial management platform, users can deposit cryptos to gain interests, or borrow cryptos and pay interests.The deposit, borrow, interest rate generation and collection are all controlled by smart contracts. The borrowing function supports users to mortgage a defined crypto and borrow other cryptos from the contract.1. Open the WanLend websiteOpen WanLend with Google Chrome, URL: https://wanlend.finance/Connect to WanMask extension wallet;The assets of your account will be displayed in your WanMask;The WanLend page is shown as below:2. Deposit assets to gain interest rateDeposit your crypto assets which are supported on this page. Now supported assets for supply are: WAN, FNX, wanUSDC, wanBTC, wanETH, and wanUSDT, 6 types of assets.After supplying, a ‘wToken’ will be generated and your interest rate will be calculated.2.1 Authorization for the first supplyExcept WAN coins, the other 5 assets need to be authorized for the first time supplying.Click a certain asset, the authorization window will pop up, click the Enable button, and confirm the authorization with WanMask;2.2 SupplyIn the supply area, click the token column you want to supply. In the supply window that pops up, enter the amount you want to deposit, then click the supply button, and confirm the deposit on the WanMask wallet.Click the “Max” button to input the maximum amount with your balance;It should be noted that the deposit interest rate here refers to the annualized rate, and it is variable with each block.2.3 RepayAssets with supply or loan will be displayed at the top of the column list first.Click on the column and select the Repay tab in the pop-up window; enter the amount you want to withdraw, click the repay button, and confirm on the WanMask wallet;Click the ‘MAX’ button to indicate that you want to withdraw all the amount within the safety threshold. if you still have loans, pay attention to that in case the value of your collateralized assets depreciates, or the value of your borrowed assets rises, then the probability that the collateralized assets will be liquidated greatly increases.If you don’t have any loan at this time, it will withdraw all supplied assets with interest rates.3. Collateralized BorrowAfter supplying the assets, the interests start to be calculated; but if you want to borrow, you need to collateralize the assets to get your borrow limit.If you have collateralized a certain asset, you can no longer borrow this asset; similarly, if you borrow a certain asset, you are not allowed to supply this asset again; the relevant columns will be automatically hidden on the page.3.1 CollateralizationClick the Collateral switch on of the asset you want to collateralize, click the “Use as Collateral” button in the pop-up window, and confirm the authorization on the WanMask wallet.You can also turn on the collateralization for assets without supplying first. In this case, once you supply such assets, it will automatically be added to your borrow limit.3.2 BorrowingIn the borrowing area, click on the asset you want to borrow. In the window that pops up, enter the amount you want to borrow, then click the Borrow button, and confirm the authorization on the WanMask wallet;Click the “80% limit” button, it will display the maximum amount within the safety threshold that you can borrow at the current market price. The borrowing interest rate here refers to the annualized interest rate, and it is variable, and will change according to the amount supply-borrow ratio of the pool.3.3 RepaymentIn borrow markets, click on the asset you want to repay, and select the repayment tab in the pop-up window;If it is the first repayment of the asset, authorization is also required;Enter the amount you want to repay, then click the repay button, and confirm the authorization on the WanMask wallet;Clicking the “Max” button to return all the borrowed amount and interest of the asset or the maximum balance of this asset in your wallet.3.4 LiquidationIn order to maintain the stable operation of the system and protect the safety of suppliers’ funds, WanLend has set up a complete set of risk avoiding and liquidation rules.If the value of your borrowed assets exceeds the loan limit, your account will be partially liquidated. This happens when the value of collateralized assets declines or the value of borrowed assets rises. Therefore, users shall pay attention to controlling risks and the price changes of related assets.The safe collateralized rate set by WanLend is 75%, which is the borrow limit (equivalent to an over-collateralization rate of 133%).The maximum safety threshold is set to 80% of the loan limit.Let’s take an example to illustrate. Assuming that 100 wanETH is collateralized when the price of wanETH is 1000$, your collateralized assets are equivalent to 100,000$.Borrow limit = collateralized assets * 75% = 75,000$The highest amount you can borrow = borrow limit * 80%=60,000$a) If the borrowed asset is a stablecoinFor example, if you borrow 50,000 wanUSDT, assuming that the price of 1 wanUSDT is always 1$, you need to pay attention to the risk of wanETH price drop;When the value of your collateralized assets, wanETH drops to 50,000 / 75% = 66,666.67$, wanETH will be liquidated;That is, before the wanETH price drops to 66,666.67 / 100 = 666.7$, you must increase the collaterals or repay the borrowing wanUSDT to avoid liquidation.b) If the borrowed asset is not a stablecoinFor example, if you borrow 50,000 WAN when the WAN price is 1$, you should pay attention to the risk of liquidation due to the price increase of WAN;Assuming the current wanETH price is N,When the value of your borrowed assets, WAN reaches (N* 100) * 75%, wanETH collaterals will be liquidated;It is equivalent to the WAN price at this time (N* 100) * 75% / 50000 = 0.0015NIf the wanETH price is still 1000$ at this time, but the WAN price rises to 1.5$, liquidation will be triggered.If the price of wanETH drops to 800$ at this time, then as long as the WAN price rises to 1.2$, liquidation will be triggered.If the wanETH price rises to 1200$ at this time, then the WAN price will only rise to 1.8$ before liquidation will be triggered.4.

UNIVERSAL MULTICHAIN BRIDGE...

Universal Multichain Bridges with Shared Staking AssetsWeijia Zhang and ZhongZhong Guo, WanchainBackgroundWanchain is a project focusing on bridging homogeneous and heterogeneous blockchains to allow assets to transfer across multiple ecosystems. Recently Wanchain released Wanchain 5.0 with a fully permissionless and decentralized crosschain mechanism to include the following advantages:• Wanchain 5.0 achieves the first implementation of open storeman meaning that anyone can join as a permission-less storeman. Wanchain community members know that Wanchain uses storeman to connect two blockchains for asset transfer. Wanchain 5.0 is the first release that makes storeman fully decentralized and changes from storeman to open storeman. Technically this is achieved through open MPC. MPC is a core technology of Wanchain to decentralize the ownership of accounts through a group of nodes, each owning a portion of a private key. At least over two-thirds of the nodes need to sign a transaction with their respective key share in order to transfer funds from an account. The MPC method combined with staking and slashing effectively prevents collusion by the storeman nodes.• The reward rate for open storeman is coupled with the reward rate of Wanchain validator’s proof of stake. This is to present staking all going to the node validator or all going to storeman. As far as we know, Wanchain is the first project to implement this coupling mechanism. It increases the stability of staking for both the block validator and the storeman validator.Wanchain provides a holistic open source crosschain suite for the 5.0 release. The Wanchain crosschain mechanism, storeman agents, P2P discovery, wallet, and browser have all been redesigned and implemented to increase performance and improve user experience.Next Steps: Scaling Wanchain Crosschain PlatformWith the release of permissionless and decentralized Wanchain 5.0, Wanchain has accomplished the basic infrastructure as laid down in Wanchain’s whitepaper. The next phase of Wanchain’s platform is to expand its crosschain capacity to support larger total crosschain values and scale up the crosschain bridges. The major problems for scaling crosschain bridges include the following:· Security issueSince Wanchain’s bridges are decentralized and permissionless, the security of the crosschain assets is safeguarded by assets staked by the Storeman nodes to ensure that there is no collusion among them and any wrongdoing by the bridge operators will be slashed with the stakes deposited for the bridges. As the number of bridges increases, the stakes needed to secure a bridge increases accordingly. Hence the limited amount of stakes to secure bridges hinder the crosschain transaction’s scalability.· Bridge capacity issueBridge capacity describes how many crosschain assets can be transferred and secured for a bridge. Today, stakes to secure crosschain transactions are bridge-based, meaning that each bridge has its own stake and the total crosschain value (TCV) should not exceed the amount of assets staked for that bridge. Since TCV is a changeable value for each bridge while stakes are allocated and attached to individual bridges, it is very likely that some bridges might have overflow of staking assets while others might hit the maximum crosschain transaction cap and need to be halted until more assets are allocated. The disparity of bridge capacities will negatively impact the overall security of the crosschain ecosystem.· Multi-Bridge compatibility issuesWanchain has started to support multi-bridge crosschain operations. One type of transferred asset in a blockchain can come from various source blockchains. For example, btc@ethereum can come from btc@bitcoin or btc@wanchain. Hence, problems arise as how we can guarantee that btc transferred from both sources are equivalent. To ensure that assets from different bridges are equivalent, the smart contract logic should be the same and the bridges should be secured. Furthermore, the operators that carry out the transfer will also be the same group of nodes that run compatible crosschain codes.To overcome the challenges mentioned above to improve scalability of the Wanchain crosschain platform, we introduce the Universal crosschain mechanism that allows a common pool of Storeman nodes to use shared staking funds to manage multi-chain bridges.Universal Crosschain MechanismUniversal Crosschain platform OverviewWanchain Universal Crosschain platform is depicted in Figure 1 with the following components: a) set client devices such as a handheld mobile device, a device having a web browser, or a desktop with applications; b) a cross-chain API gateway that is connected to client devices and various blockchains, bridges, and blockchain hubs; c) homogenous or heterogeneous blockchains; and d) universal cross-chain bridges that connect blockchains to provide native or cross-chain transactions. Cross-chain API gateways as shown in the diagram may be implemented with different technologies. For example, an API gateway may have an HTTP server as a front end that communicates with client devices. In another embodiment, the API gateway may have a peer-to-peer connection with a client device and receives messages from the clients. The API gateway may also implement a load balancing server to increase the scalability and reliability of the gateway. The backend of the API gateway connects to native blockchains, bridge links, or blockchain hubs. A native blockchain is a blockchain that supports single chains and protocols, such as bitcoin, Ethereum, quorum, EOS, tron, corda, ripple, and hyperledger. A blockchain hub is a blockchain that has functions to perform cross-chain operations to transfer and aggregate assets, data, and value across blockchains. Blockchains such as Wanchain, Polkadot, and Cosmos may be classified as blockchain hubs.Figure 1 Overview of Universal Crosschain PlatformIn this architectural diagram, a blockchain bridge is a connector that connects two homogeneous or heterogeneous blockchains to allow data, value, and assets to flow across blockchains. The Wanchain bridge solution is implemented via Storeman nodes. A Storeman mechanism is a component node that is used to listen to events on multiple blockchains and processes and relays the transaction to the corresponding blockchains. A storeman node may have multiple running programs to form a cluster and each shares part of the secret for unlocking the accounts that stage the cross-chain values. The storeman mechanism will support staking that allows users to lock a portion of their assets through a smart contract to fund the running node and receive a reward for the cross-chain transaction.Storeman NodesStoreman node components can be shown in Figure 2. A cross-chain bridge or Storeman may have two or more ports connecting to corresponding blockchains. A port may contain executable codes such as smart contracts, chain code, or scripts that may be used to perform operations on a blockchain to which it is attached. The executable code then transfers the operation and data to the bridge for further processing through the services in the cross-chain bridge. These services may include a validation agent to validate a cross-chain transaction, a sync agent to synchronize data and states among bridges, and an event agent to listen to and process events. Storeman nodes also network with each other to form a multi-party computing (MPC) group to control a shared key to lock and unlock accounts on both source and target blockchains.Figure 2 The architectural components of a crosschain bridgeShared staking funds for Storeman nodesIn a universal crosschain platform, accounts in the blockchains may fund a bridge by locking a certain amount of assets in the blockchains in return for a reward of cross-chain transaction fees. This may be done by implementing smart contracts on a blockchain for a staking function such as stake_deposit as a function of blockchain_id, account address, amount, Bridge_id, duration, and signatures to fund a bridge. Here, blockchain_id represents a blockchain where the account is located, the account is a blockchain EOA (external owned account) from which a fund will be withdrawn or locked to support a bridge to process cross-chain transactions, the amount is the amount of the asset that will be deposited, bridge_id represents the bridge for which the fund will be deposited, the duration is the length of time when the asset will be locked in the account, and signature is a signed message from the account owner to enhance the authenticity of the staking request.Once account owners deposit their assets to the bridges, they accumulate stakes for the bridge fund (Figure 3). A bridge fund is the aggregation of the assets and value deposited to bridges in a bridge group. A bridge stake is a total stake deposited to a particulate bridge. A stake and an asset do not need to have a 1-to-1 matching relationship. For example, a stake may be a function of asset value with modifiers such as length of deposit time and other promotional factors such as deposit time or even a random lucky number. These multi-bridge stakes form the basis for the selection of bridges for processing cross-chain transactions as well as the basis for rewards. In general, the larger the stake a bridge has, the more chance for it to be selected as a Storeman node. Similarly, the larger the stake an account has, the larger the portion of the reward that account will receive.Figure 3 Shared Bridge StakesOne important change for a universal crosschain platform is that the staked funds are shared among bridges and hence are “need-based” and can be dynamically allocated to bridges that carry out the transfer of crosschain assets.Advantages of Universal CrosschainWhen compared with the existing Storeman node solution that Wanchain has, the shared Storeman node mechanism has several advantages in security, crosschain transfer capability, and scalability as shown below:Much simple process of transferring tokens from chain to chainFigure 4 Schematic diagram showing differences of crosschain transfer via regular storeman nodes (top) and shared storeman nodes (bottom)Shared storeman group makes the asset management and information verification between different blockchains much easier and the process of transferring tokens from chain to chain simpler as shown below.The diagram shows a scenario where there are three blockchains of Ethereum, EOS and Wanchain respectively. Each blockchain has transferred bitcoin marked as wanBTC. For the regular storeman node (top of diagram) mechanism, two storeman groups are created with storeman group 1 (SG1) for the Ethereum and Wanchain bridge and storeman group 2 (SG2) for the Wanchain and EOS bridge. The workflow of transferring wanBTC from the Ethereum blockchain to the EOS blockchain follows the steps below:Step1: User burns his wanBTC on Ethereum;Step2: SG1 receives this event and mints the same amount of wanBTC for the user on Wanchain;Step3: User burns the received wanBTC on Wanchain;Step4: SG2 receives this event and mints the same amount of wanBTC for the user on EOS;In the above procedure, a total number of 4 transactions are required, including 1 transaction on Ethereum, 2 transactions on Wanchain, and 1 transaction on EOS. Among these 4 transactions, the user is required to send 2 transactions — 1 transaction on Ethereum and 1 transaction on Wanchain.With the shared Storeman group (shared SG), the procedure is simplified as follows:Step1: User burns his wanBTC on Ethereum;Step2: shared SG receives this event and mints the same amount of wanBTC tokens on EOS;In the above procedure, a total number of 2 transactions are required, including 1 transaction on Ethereum and 1 transaction on EOS. Among the 2 transactions, the user is required to send 1 transaction on Ethereum.Low cross-chain transaction fee for usersFrom the above we know, using the shared storeman group, that the user is required to send only one transaction to transfer his tokens between two different chains with no direct bridges. Thus the cross-chain transaction fee is 50% lower than before.Low cost of building bridgesFigure 5 Comparison of resource consumption between regular and shared storeman groupsIn Wanchain 5.0, the locked account is generated jointly by the members of the Storeman group, which is denoted as the KeyGen process. This process requires all the members to participate and is both time and computationally consuming. Specifically, the total runtime and computation resource consumption grows linearly as the number of bridges increases. Using the shared Storeman group, only one KeyGen process is required, for the locked account is shared by the bridges. Thus, the total runtime and computation resource consumption remains constant as the number of bridges increases. Assuming the resource consumption in building one direct bridge is C, then the relationship of the total resource consumption and the number of building bridges is shown in Figure 5 above. Per this graph, the resource consumption for a regular storeman group increases in proportion to the number of bridges while the consumption for a shared storeman group remains constant.Better securityFigure 6 Difference of regular storeman group and shared storeman group for security considerationCompared to separating the Storeman nodes into different groups, a single Storeman group with more members offers better security. We show this fact through a simple example.Figure 7 Relationship of overall security of storeman groups versus affecting parametersFigure 8 Security computation for p=0.3 and TN=100Figure 9 Security computation for p=0.2 and TN=100Figure 10 Security computation for p=0.1 and TN=100Figure 11 Graph showing how the level of security is impacted by number of storeman groups nodesFrom the above diagram, it is clear when the individual probability p of a Storeman node being hacked is high, the shared Storeman node mechanism shows improvement in security. When p values decrease, the security improvement is not as significant, but it still shows theoretical advantages for shared Storeman nodes.The diagram from Figure 11 also shows that the lower number of storeman groups, the higher the security level for the overall system.Better flexibilityStoreman group’s collateral is used to ensure the security of cross-chain assets; therefore, the value of cross-chain assets must not exceed the Storeman group’s collateral. Problems arise when the Storeman group’s collateral does not match the cross-chain demand, which results in poor collateral usage. An adjustment factor can be introduced into the Storeman reward mechanism to relieve this problem. But this factor is fixed during Storeman’s working cycle, so this solution is not that perfect. Using the shared Storeman group, different bridges share the same collateral pool. Bridges with more cross-chain demand will “occupy” more collateral, while bridges with less cross-chain demand will “occupy” less collateral. All this happens naturally according to the real cross-chain demand. We show this through a simple example.Assuming there are three Storeman groups, each of which builds a direct bridge and has the same collateral of value 1000 USDT, the Actual Cross-chain Value is calculated as:Actual Cross-chain Value = Min{Collateral, Cross-chain Demand}The details are shown in the figure below. Then we can calculate the Collateral Usage Rate:Collateral Usage Rate = (Total cross-chain value)/(Total collateral)= (500+1000+800)/(1000+1000+1000)= 76.7%Figure 12 computation of collateral usage for regular storeman groupsBy shared Storeman group, we have a higher cross-chain value, which is shown in the figure below.Figure 13 computation of collateral usage for shared storeman groupsThen we can calculate the Collateral Usage Rate:Collateral Usage Rate = (Total crosschain value)/(Total collateral)= 2800/(1000+1000+1000)= 93.3%Higher crosschain capacity for a single bridgeFigure 14 comparison of crosschain capacity of regular and shared storeman groupsThrough the shared Storeman group, all the bridges share the same collateral pool. While the total cross-chain capacity remains unchanged, the maximum cross-chain capacity for a single bridge increases to the value of the total collateral. This improvement helps us handle the situations where the value of cross-chain assets exceeds the collateral behind a single bridge.ConclusionUsing shared storeman group, Wanchain will develop a universal crosschain mechanism to dramatically improve the scalability and security of crosschain bridges. This project is in process and there should be a shared storeman group release in the coming quarters.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Say Hi to the Newest Member...

Upcoming: An Ethereum-based DeFi WanFarm & A Major Upgrade to Wanchain’s Cross-chain MechanismWanchain’s cross-chain DeFi ecosystem ushered in great development. Cross-chain DeFi projects such as WanSwap and WanLend were born successively and achieved great success. With the continuous development of Wanchain’s cross-chain mechanism and the growth of the Wanchain ecosystem, users from the community will definitely put forward more stringent requirements and more refined demands for decentralized financial services. A group of community-driven projects that keep pace with times, such as the AMM DEX WanSwap, and the Cross-chain Lending Platform WanLend, have emerged at this stage.In late January this year, WanFarm, a new DeFi project developed by the Wanchain team, will be expected to launch on Ethereum and will open up yield farming on Ethereum using cross-chain wanTokens.WanFarm is a yield farming DeFi DApp deployed on Ethereum. In the initial stage, users of WanFarm get LP tokens by providing asset pairs (e.g., WAN@Ethereum and USDT) to AMM DEX (e.g., UniSwap), and stake their LP tokens on WanFarm to earn real-time farming rewards in WAN.WanFarm aims to promote a series of coins and tokens, such as wanBTC, wanDOT, wanXRP, wanEOS, wanTRX, etc., on mainstream public chains to be cross-chain integrated into Ethereum, which contributes sufficient liquidity to these AMM DEXes (e.g., UniSwap, SushiSwap) on Ethereum, and offers richer types of borrow & lend cryptocurrencies for lending dapps (e.g., Compound, Aave), so as to make Wanchain cross-chain assets form a scale effect in the huge and rich Ethereum ecosystem. At the same time, the increasing usage of cross-chain assets on Ethereum can in turn further accelerate the construction of cross-chain wanBridges. Driven by economic interests, Storeman nodes will continue to widen the wanBridges (that is, to ensure the quota of cross-chain assets by staking more collaterals), and build up new cross-chain wanBridges (that is, to make more new assets to be cross-chain transferred to Ethereum by integrating new public chains with Ethereum). Therefore, Wanchain’s cross-chain mechanism and DeFi applications will develop hand in hand and complement each other.For the details on cross-chain DeFi projects in the Wanchain ecosystem, please see:FinNexus OptionsWanSwapWanLendDark ForestWandora BoxJack’s PotQ1 2021, A Major Upgrade For Wanchain’s Cross-chain MechanismFor Wanchain 5.0, there is a one-to-one correspondence between a wanBridge and a Storeman Group. Therefore, to connect any two public chains, at least one Storeman Group must be created between the two. Under this mechanism, if a Storeman node wants to participate in multiple wanBridges of connecting different public chains, the node operator must run multiple Storeman nodes in different Storeman Groups. Obviously, this situation increases the difficulty of operation for node operators. The deposit funds among different Storeman Groups are independent and cannot share the cross-chain quotas with each other. So, the utilization rate of the deposits is low, which results in the intensive economic bandwidth of busy wanBridges and wastes economic bandwidth of leisure wanBridges. Theoretically, this mechanism has a small security risk of collusion among Storeman nodes.For the reasons above, considering the efficient utilization of resources, the improvement of cross-chain security and the optimization of user convenience, the Wanchain cross-chain mechanism will undergo one more major upgrading on the basis of 5.0. It is expected that the upgraded Storeman Group mechanism will be launched in Q1 2021.At that time, a Storeman Group will uniformly manage all wanBridges which connect two different public chains, and the staking deposits will also serve as the common deposit for all wanBridges in the entire cross-chain network.For more details on the new generation of Wanchain’s cross-chain mechanism, please stay tuned for more details. We will share more detailed articles in the next two months.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

“reHash” — Your Weekly Summ...

Rewards will be issued daily as usual during the withdrawing period.Nodes who do not register to exit before the end of the current period WILL be included in the selection process for the next periodHow To Create A Storeman NodeIn general, the rewards rate of running a Storeman Node is about 50% higher than the rewards rate of being a delegator. To set up a node, users need to at least well prepare the following two things:You need to have enough WAN to stake to the Storeman node you created. Those WAN coins can be either totally contributed by yourself or partly from partners and delegators through the way of Partner In and Delegation. In short, the top 20 Storeman nodes with staking amount will finally enter to the Storeman Group.You have to buy the cloud service on AWS, Google Cloud or Ali Cloud, etc, and deploy your node on the cloud.For the detailed operations of how to set up a Storeman, please go to Wanchain 5.0 Mainnet Storeman Setup Guide.Milestones Hit by the First Storeman Group8.3 Million WAN Staked!The total staking amount of current Storeman Group has increased significantly, from 2.2 million WAN on November 15th to 8.34 million WAN as of December 27th.APY of Up to 13.98%Storeman Group APY has increased steadily, from APY 11.9 on November 15th to 13.98% as of December 27th (APY is priced in WAN).Notice: Storeman Group APY is an average measure of both node and delegator APYs. Therefore, APY of Storeman nodes is higher than 13.98%, while APY of delegators is lower than 13.98%.Over $2.3 million in Cross-chain AssetsThe value of cross-chain assets including BTC, ETH, EOS, USDT, and more now exceeds 2.3 million USD.At present, there are primarily 6 types of WRC20 tokens on Wanchain, namely WAN (and wrapped WAN), wanETH, wanBTC, wanUSDT, wanUSDC, and wanEOS.The total value of cross-chain assets on Wanchain has reached USD 2.31 million on December 27th, 2020 and continues to grow.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

WanLend — The First Cross-c...

WanLend — The First Cross-chain Lending Platform on Wanchain Is Live!WanLend is the first ever Wanchain based decentralized lending platform, and it goes live today!This is the second major DeFi DApp to go live on Wanchain since the launch of Wanchain 5.0, the first being the Uniswap instpired AMM DEX, WanSwap.WanLend is LIVE now at: https://wanlend.finance/What Is WanLend?WanLend is the crypto lending platform built on Wanchain which takes advantae of Wanchain 5.0’s cross-chain features. WanLend is developed, deployed and operated by WanLabs, and it is the first decentralized cross-chain lending application in the Wanchain ecosystem.WanLend fully draws from Compound’s code and design, and relies on similar algorithms to calculate the supply rate and borrow rates of each cryptocurrency in accordance with the supply and demand.At launch WanLend supports supply and borrow features for WAN, wanBTC, wanETH, wanUSDT, wanUSDC, and FNX. In the future WanLend will support more cross-chain tokens (e.g., XRP, DOT) and native Wanchain DApp tokens.Cross-chain wanTokens can be obtained by converting native tokens through WanWallet Desktop and wanBridge Web, or can be traded for through WanSwap. Right now, users can use WanMask to operate WanLend. WanLend will be integrated into WanWallet Desktop and WanWallet Mobile in the future.WanLend Users:The SupplierAssets put up by suppliers are pooled together. Using on chain pool management ensures the maximum liquidity of the funds, and also guarantees the security and transparency of the assets.The supplied assets can be withdrawn at any time once after being deposited, which greatly faciliates the flexibility of funds for an individual supplier.The BorrowerBorrowers supply certain approved assets as collateral on WanLend. WanLend calculates the borrow rate in real time — the rate is transparently determined by the on chain supply and demand for different assets. Borrowed assets may be fully repaid at any time at discretion of the borrower.WanLend Features:Support for assets from different chains: WanLend not only supports Wanchain WAN and WRC20 tokens, but more importantly, supports any cross-chain tokens from integrated public chainsHigh TPS and low gas fees: WanLend takes advantage of Wanchain’s low gas fees and lightning fast transactions. Currently, the gas price on Wanchain is 1 Gwin, so the transaction fee is only one thousandth of that of on Ethereum.Flexible terms:Assets can be supplied or withdrawn at any time, and borrowed assets can be borrowed and repaid at any time, bringing a high degree of flexibility for both suppliers and borrowers.Synergy with the Wanchain cross-chain DeFi ecosystemThe cross-chain lending platform WanLend and WanSwap complement each other, as more and more DeFi applications join the Wanchain ecosystem, they will synergistically bring value to each other.WanLend at a GlanceThe homepage:User’s lending status and available tokens.The supply page:View supply detailsThe borrow page:View borrow detailsWanLend User GuideWanLend User Guide LinkAbout WanLabsEstablished in 2018, WanLabs is committed to the integration and innovation of cutting-edge blockchain technology and applications.

Comparative Analysis of wan...

With the release of Wanchain 5.0, a new decentralized crosschain solution has been implemented already! In the last article, I analyzed the renBTC crosschain solution, and I also mentioned that wanBTC will have a significant improvements over Ren’s solution in terms of decentralization and security mechanism. At the same time, many readers asked me about another project tBTC, which is aother project that wraps BTC on Ethereum. This article will analyze some designing and implementations of the similarities and differences between tBTC with wanBTC. And I wish to give readers a different perspective to view these BTC-wrapped solutions.Let’s take a look at the designing mechanisms of tBTC and wanBTC. Firstly, both projects are trying to use more decentralized ideas to achieve interoperability/crosschain. Objectively speaking, neither can fulfill the ‘perfect’ state of 100% ‘absolute decentralization’ due to the bottleneck of the existing technologies. In addition to the core cryptographic technology that ensures the security of crosschain locked accounts, wanBTC and tBTC both use ‘extra’ economic measure to ensure the security of users’ native BTC assets, even if the extreme technical ‘black swan’ incident happens! This economic measure is the ‘collateral’ mechanism.In tBTC’s design, the node that manages native BTC assets is called ‘Signer’, while in wanBTC, the node that also manages asset is called ‘Storeman Group’. Both tBTC and wanBTC require collateral deposits for the ‘signature’. The difference is that the Signer of tBTC uses 150% Ether for the ‘over-collateral’ and the Storeman of wanBTC uses a 200% WAN coins as ‘over-collateral’.Such mechanism of over-collateralization is a very good protection for locking the original assets in addition to technical guarantee. It can be regarded as ‘Double Security’. One more thing to add, since it is over-collateralized, for the price spot and liquidation settlement of the collaterals against BTC, tBTC uses MakerDAO’s single price feed while wanBTC uses the ‘BIO’ multi-oracle to acquire the price from different sources.After talking about the similarities, let’s look at the differences between the two projects. The first is the different design of the TSS Threshold Signature in cryptography. wanBTC and tBTC are both based on the latest TSS program research results “Fast Multiparty Threshold ECDSA with Fast Trustless Setup”. In terms of parameter settings, the threshold used by tBTC is a setting of 3–3, which means that each crosschain transaction has 3 “signatures” to manage the accounts that lock the original BTC assets, and these 3 signers need to participate in sending a legal signature. If any signer goes offline or refuses to sign, the two steps of a crosschain transaction: “locking” and “minting” cannot be completed. This is regarded as a kind of “No Fault Tolerable”.The threshold adopted by wanBTC is a 15–21 design, that is, each crosschain transaction is managed by 21 anonymous nodes, and each transaction requires the participation of 15 Storeman nodes to complete the crosschain locking and minting. In other words, every time when a crosschain transaction occurs, it is allowing no more than 6 nodes of the 21 Storeman to be offline or refuse to sign. Thus this design can be considered as a kind of ‘Fault Tolerable’. When a large number of crosschain transactions happen, “allowable fault tolerance” is more practical than “no fault tolerable”.In addition to the TSS threshold setting, the second difference between the two mechanisms is that the ‘split’ setting of the native Bitcoin. Because tBTC uses a small group of three ‘signers’ to sign mentioned above, it is more likely these three signers to conspire and ‘steal’the native Bitcoin, so tBTC uses ‘discrete values’ to prevent such behavior. For example, if a user operate one crosschain transaction of 1.63 BTC, tBTC may discretize the number 1.63 into 1 piece of 1BTC, 1 piece of 0.5BTC, 1 piece of 0.1 BTC, and 3 pieces of 0.01 BTC, so it is handed over to (1+1+1+3) 6 ‘three signers’ groups for processing. Although the security has been improved to a certain extent, from a practical point of view, it also means that the user’s transaction of 1.63 BTC needs to wait for 6 times of the Bitcoin network finality confirmation, and it also needs to pay 6 times gas fee for the Bitcoin network as well as 6 times ‘minting’gas fees on Ethereum. Looking at the very expensive gas fee on Bitcoin and Ethereum networks nowadays, I doubt whether this discrete setting like tBTC can be implemented. In other words, if you stick to the discrete value setting, basically users who want to transfer a small amount of BTC to Ethereum will need to pay a big amount of gas fees in total. Meanwhile, wanBTC adopts the design of 21 “Storeman” nodes and as long as the collateral is greater than the crosschain transaction amount, the transaction of 1.63 BTC in this example will need only one time waiting time as well as gas fee for Bitcoin network, and only one ‘minting’ fee on Ethereum. Of course, when the collateral of the ‘Storeman’ group is not enough for the BTC crosschain transaction, the mechanism setting will not allow such transaction to be implemented to ensure the security of the original BTC asset.Another difference between these two is the logic of contract interaction. As we know, the contract interaction logic determines the waiting time and gas fee consumed for crosschain transactions, so we take a 1BTC transaction for example: when user requests to transfer 1 BTC to 1 tBTC on Ethereum, the process is that the user needs to send 1 time 1BTC ‘lock’ transaction and 1 time of contract interactions on Ethereum for ‘Request (request for coin ) ‘and 1 time of ‘Proof (the original BTC is locked and the evidence is submitted to the contract)’; in addition, tBTC has to ‘select’ different groups of ‘3 signers’ for such transaction; and wait until the selection of the groups of ‘signers’ is completed that they can send the generated BTC locked address to the user to ‘stake’their Bitcoin. It will take a longer time with a user poor experience.In the Wanchain crosschain mechanism, when users request to send BTC to Ethereum to mint wanBTC, since Wanchain’s “Storeman” group selection is not completed based on each transaction, but the selection is finished in advance, so the selected “Storeman’ group will send the address of the locked BTC address directly to the user, and there is no need for the user to send any transactions to Ethereum. According to the settings of these contract interaction logic for wanBTC, it is predicted that the transfer time of tBTC will be about 1–3 times longer than that of wanBTC (tBTC: discrete setting plus two Ethereum transactions), and the gas fee payment will be 3–10 times higher (tBTC: Ethereum transaction fee) *2 + Bitcoin transaction fee *1 + 0.005 BTC / Wanchain: Bitcoin transaction fee *1).The last point of the differences is that tBTC requires users MUST to ‘redeem’ their tBTC after 6 months, while wanBTC does not have such a deadline, and users can hold wanBTC as long as they want. Such a “strange” requirement is because in tBTC mechanism, the minted tBTC is managed by a separately selected group of ‘3 signers’, and if the user does not redeem the tBTC to original BTC, these ‘ 3 signers’s node cannot exit the network but have to wait there. Therefore tBTC forces users to “redeem” after maximumly of 6 months; while wanBTC’s “Storeman” group is not served only for a single transaction, and with every calendar month ‘Storeman selection’ is finished, the old group will hand over the ‘balances, debts and rewards’ to the new group so any single Storeman group node can exit. Thus users are not required to “redeem” the minted wanBTC assets within a certain period of time.In general, from the comparative analysis stated above, we can say that both tBTC and Wanchain’s wanBTC followed the professional and serious ‘trustless’design logic and made quite technical and engineering breakthroughs in the implementation of ‘decentralization’ and ‘security’.Both parties have adopted TSS’s latest threshold cryptography research results, but because of the different thresholds obtained, a series of different settings have been used in engineering and coding, which has caused some similarities and differences. Going back to what I said at the beginning of this article, no crosschain mechanism is absolute ‘100% technically safe’ at the moment so when crosschain node collateral, economic slashing and incentive rules are introduced, they greatly improved the crosschain technology. We advocate here any further efforts from different projects and teams to promote the crosschain technology and the application wrapped tokens rather than only telling the crypto industry something only exist in their whitepapers without any adoptions at all!Comparative Analysis of wanBTC with tBTC was originally published in Wanchain on Medium, where people are continuing the conversation by highlighting and responding to this story.

WanMask Guide

In this guide, we will explain how to use WanMask, the browser extension wallet on Wanchain.— WanMask is a free and secure browser extension that allows web3 applications to read and interact with the Wanchain blockchain. It is almost identical to MetaMask, if you are already familiar with MetaMask, you can probably skip this guide.How to create a wallet with WanMask?In this section, we explain how to install and create a new wallet with WanMask.1. Install WanMask on your browserTo create a new wallet with WanMask you need to install the extension first.You can install WanMask for Chrome, Brave and Opera browsers from the Google Chrome web storeClick on ‘Get Chrome Extension’ and then ‘Add to browser’Click ‘Get Started’In the next screen, you can either import a wallet or create a new one. For this guide, we will create a wallet. It’s also possible to import a Wanchain wallet you already created by seed phrase.Create a strong password and accept the terms of use. We recommend you follow best security practices by using a secure encrypted password manager such as LastPass, or at least make sure to follow XKCD’s famous password advice on making a password which is easy to remember but hard for computers to crack:In the next step you need to write down your seed phrase. Never disclose your seed phrase, anyone with this phrase can take your assets permanently! Click on the box to reveal the words. Write down the words in the order they are presented. When you’re done, click ‘Next’.Click on the words presented in the same order as you wrote them down. This is an extra step to make sure you wrote down your seed phrase. When you are done, click ‘Confirm’. Be certain to secure your seed phrase in a safe location offline.Congratulations! You have successfully created a wallet for WanMask. In the next section, we will explain how to use it:How to use WanMaskYou can use WanMask with Web3 applications on WanChain like WanSwap and WanBridge. Additionally, you can use it for sending normal WAN and WRC20 transactions.The interface:“Account”You can click on your account name to copy your address to the clipboard.“Send”You can use this to create a transaction. Put in the recipient's address first. After that, you can fill in the details. More on this later in this guide.“Add Token”Here you can add other WRC20 tokens. You can either add them by searching for the name of the token or by searching the address of the token. After selecting the token, click ‘Next’ and confirm on the next page. The token and balance will now be visible in assets. When adding a token by address directly, make certain that you got the address from a trusted source!! Anyone may issue a token with any name on Wanchain, so don’t let yourself be fooled!“Assets”Here you can see your balance of each token.“My Accounts”When you click on the icon in the top right you can view your accounts, add accounts, add a hardware wallet and go to “Settings”.Connecting Hardware WalletWanMask supports Ledger and Trezor wallets. You can add them by clicking on “Connect Hardware Wallet”, and following the steps provided. Make sure your wallet is connected to your computer and that it’s set up with a Wanchain wallet before you do this. See our guides for setting up Ledger and Trezor for Wanchain.“Settings”In settings, you can customize WanMask. We will go through some of the settings here.“Security & Privacy”Here you can reveal your seed phrase if you lose it.“Advanced”In “Advanced”, you can reset your account, this will clear your transaction history.You can also enable advanced gas controls, which gives you more options over how you set up your transaction. Use this with caution! If you’re not careful, youi could end up spending your entire balance on gas!! (Like this guy who spent over 100 thousand USD for gas on a single transaction…) You also need to switch on each option for the advanced gas controls separately.The options are:Transaction TimeShow Hex DataShow Conversions on TestnetCustomize Transaction NonceAuto-Lock TimerThe last option in advanced is Auto-Lock Timer, here you can set the idle time after which WanMask will become locked.TransactionsIn this part of the guide, we will go into detail on transactions.Making a custom transactionClick on ‘Send WAN’ on the main interface. Put in the recipient's address and fill out the amount you want to send and click ‘Next’.On the next screen, you can edit the gas price and limit. Normally these should be fine like they are. If you want to speed up your transaction you can edit them. You need to enable advanced gas controls in settings to do this. If you don’t want to do this click “Confirm” to process your transaction and you are done. More information on editing the transaction next.Customize gas feesIf you click ‘Edit’ on the gas fees you get two options, ‘Basic’ and ‘Advanced’. In the basic screen, you can choose between 3 options: slow, average, and fast.In the advanced screen, you can edit the gas fees manually and see live gas price predictions. Like we mentioned above, be very careful when manually entering gas fees as it is easy to make a mistake and spend way more than you intended — like thousands of dollars more sometimes!!! (Although that is very unlikely on Wanchain)Using WanMask with web3 applicationsAs said before you can use WanMask with Web3 applications like WanSwap and WanBridge. To do this, go to the website of the application and connect your wallet (you will see the option on the website). By doing this you can use your wallet with this site.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

It’s NOT from Wanchain official dev team. The private key is stored locally with no security risk of exposure.Explore in the universe, occupy planets, and collect resources.Resources are divided into two types: ‘Energy’ and ‘Silver’.Energy is used for resource transportation and planet occupation, and silver mines are used for planet upgrade.Level 0 planets cannot be upgraded or stored silver mines.Each planet can automatically increase its energy until it reaches the energy limit.Only some special planets can produce silver mines.(As shown in the picture below: the lightning icon is the energy, and the ZK icon is the silver mine)Each planet has a natural level. Level 0 is the lowest and cannot be upgraded. Planets level 1 and above can be upgraded through using silver mines.Click the planet, and click the details button to view the detailed information of that planet.Detailed information is shown below:The UP arrow in the bottom indicates that this planet can be upgraded.After clicking, you can see that there are 3 upgrade directions: defense, range, and speed. (As shown below)When the number of silver mines is reached, you can upgrade.Multiple players can attack each other’s planet.It takes extra energy to occupy a planet with wild monsters.The dotted circle displayed after the planet is selected represents the distance that the current energy can reach. The longer distance, the more energy is consumed. (As shown below)After selecting a planet, click the ‘Send Resources’ button to start carrying resources to other planets. Below, you can use the lightning icon or the up and down arrows to select the amount of energy as well as the silver mines carried by that trip.Planets with energy shields or wild monsters need extra energy to occupy. You can use the energy of multiple planets to consume the energy shield little by little until the energy is zero and occupy it.You can click to buy ‘HAT’ , and use $WAN coins to purchase and upgrade the hats. Hats have different patterns.Tap the ‘+-’ symbol in the upper left corner of the screen to quickly zoom in and out of the map.Click the settings button in the upper left corner to export the private key, coordinates, and map. These three elements are essential to resume this game.The map is continuously expanded and explored through the hash computation.Exploring the map consumes more CPU, you can click the pause button to stop and continue exploring at any time.You can bind your Twitter account in the upper left corner and give yourself a customized account name.Each planet can be created as a Non-fungible token (NFT). The red circled part represents this NFT’s unqiue ID. In the future, such NFT tokens can be traded among users through another NFT trading platform by using WAN coins.Finally, have fun with Dark Forest and create your unique NFTs!How to Play the ‘Dark Forest’ was originally published in Wanchain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Say Hello to wanBTC & Frien...

Say Hello to wanTokens, the Newest Cross-chain Assets to Hit EthereumWanchain 5.0’s Storeman Node based cross-chain bridges bring decentralized, permissionless, and trustless BTC, EOS, and WAN to EthereumIn my recent articles on Medium and discussions with our community members on Twitter and Telegram I have analyzed several different crosschain BTC solutions/projects such as REN (renBTC), Keep (tBTC), and others.With the upcoming launch of wanTokens on Ethereum (Wanchain 5.0’s Storeman Node Bridge powered cross-chain assets), you may be wondering why and how we are bringing wanTokens to Ethereum, and how they fit into the current landscape of cross-chain assets.We have all been witness to the recent DeFi explosion, however that rapid growth has begun to hit some speed bumps. There are many reasons behind this decline, but one very important one is a lack of high quality assets on Ethereum itself. On Compound.Finance, there are only seven supported assets: BAT, DAI, ETH, USDC, USDT, wBTC and 0X. Among them, three of them are stable coins, and one is from another blockchain. This is despite the fact that there are over 10,000 other ERC20 tokens on Ethereum.This clearly illustrates the problem that Ethereum assets alone cannot sustain the DeFi ecosystem. Here at Wanchain we have anticipated this issue, and it is why we have spent the last 3 years developing a decentralized crosschain mechanism which enables native tokens on other public chains to swim into Ethereum DeFi in the form of wanTokens. The first wanTokens to launch on Ethereum will be wanBTC and wanEOS, and will soon be followed by wanXRP, wanDOT, and many more.Given the demand for more high quality assets from other chains on Ethereum, we expect that quite a few DeFi protocols will beeager to include wanTokens into their system. We envision wanBTC and wanEOS being used as collateral on protocols such as Compound or Cream for lending and borrowing, and in asset pools on Curve or Swerve and many others. The inclusion of a diverse array of high quality assets from other chains would give any DeFi protocol a big competitive advantage.‘A journey of a thousand miles begins with a single step’.The launch of wanTokens with Wanchain 5.0 is the result of years of hard work, research, programming, and analysis, and we will soon introduce the fruits of our labor to the world.First we launch Wanchain 5.0 in a closed Beta on the testnet, followed by an open Beta testing phase which the whole community can participate in. In this phase, testers can help by taking part as Storeman node operators, delegators, or even regular users. We will publish more about our testing procedure as well as a thorough code audit before launching the mainnet around end of October.Wanchain ecosystem partners:Wanchain’s ecosystem partner FinNexus will be using wanBTC as one of its collaterals in its MASP liquidity pool for their BTC option DeFi product. wanBTC will not only be the underlying asset in FinNexus but also wanBTC holders will be distributed the yield mining rewards in FinNexus’ token, FNX. We will continue to reach out to more DeFi projects and encourage them to integrate wanTokens.FinNexus OptionsAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

wanBTC和tBTC的对比分析

随着Wanchain5.0的发布,一个全新的去中心化代币跨链的方案呼之欲出。我在上篇文章中分析了一下市场上比较热的renBTC的跨链方案,其中也提到了wanBTC在去中心化和安全机制上会比ren的方案有大幅的提高,同时很多读者朋友向我们咨询关于另外一个同样是在以太坊上发行映射BTC的项目tBTC的技术情况,正好本文借分析tBTC和wanBTC的相同和异同的一些思路和实现方案,给读者不同的视角来评判这些映射BTC的解决方案。先看看tBTC和wanBTC比较相同的一些设计机制。首先是两个项目都尝试用更加去中心化的思路来实现跨链,客观来说,都没有能够达到100%的去中心化理想状态,这也是现有技术的发展瓶颈决定的,所以在用密码学技术保证跨链锁定账户安全这个核心点之外,都采用了‘额外’的经济手段来保证一旦技术手段还是出现‘黑天鹅’情况下用户原生BTC资产的安全性,也就是通常意义上所说的‘抵押物’机制。在tBTC设计中,管理原生BTC资产的节点被称为‘Signer’可以翻译成‘签字人’而在wanBTC中,同样管理资产的节点被称为‘Storeman Group’,可以翻译成‘看门人’。tBTC对‘签字人’和wanBTC对‘看门人’都要求其抵押保证金才能工作,不同的是tBTC的‘签字人‘用的是以太Ether按照150%做‘超额抵押‘和wanBTC的’看门人‘用的是WAN代币做200%或者更高的’超额抵押‘。这样有超额抵押的机制是对锁定原生资产除了技术手段外一个非常好的保护,可以看作是’Double Security双重安全机制‘。多说一句,既然是超额抵押,抵押物对BTC的价格计算和清算设置上,tBTC用的是MakerDAO的喂价而wanBTC用的是BIO多重预言机来进行喂价。说完相同点,说一些两个跨链机制不同的地方。首先是跨链密码学上核心的‘TSS门限签名‘的不同设计。看过我们上篇文章的朋友应该都还记得,市面上绝大多数跨链密码学是基于’Threshold门限‘的基础,而wanBTC和tBTC则是基于最新的TSS方案研究成果“Fast Multiparty Threshold ECDSA with Fast Trustless Setup”。参数设置方面,tBTC采用的门限是3–3的设置,翻译过来意思就是每笔跨链交易有3个’签字人‘来管理锁定原生BTC资产的账户,并且这3个签字人都需要参与构造一个合法签名。如果有任何一个签字人掉线或者拒绝签字的话,一笔跨链交易的两步:’铸造‘和’赎回‘都无法完成,可以看作是一种’No Fault Tolerable不允许容错’。wanBTC采用的门限是15–21的设计,也就是每笔跨链交易有21个‘看门人’来管理,而每次交易需要其中的15个人参与就能完成跨链的铸造和赎回,换句话说每次跨链交易发生的时候,允许这21个看门人中有不超过6个节点有掉线或拒绝签名的情况发生,可以看作是一种’Fault Tolerable可允许容错’。当大量跨链交易发生的情况下,’可允许容错‘比’不允许容错‘更加实用。除了TSS门限设置外,两个机制的第二个异同点是对跨链BTC额度的‘拆分’设置。因为上面第一点讲到了tBTC采用的是3个‘签字人’组成的小组方式来签名,的确这三个人合谋作恶的可能性比较大,所以实际跨链操作中,tBTC会采用‘离散数值’的方式来处理一笔BTC的跨链交易金额,翻译过来说,举个例子,一个用户做一笔1.63个BTC的跨链操作,tBTC可能把1.63这个数字离散为1个1BTC,1个0.5BTC,1个0.1BTC,3个0.01BTC,这样交给(1+1+1+3)6个‘三人签字人’小组来处理。这样做虽然安全性得到一定的提升,不过从实用性上来看,这也同时意味着用户的这‘一笔’1.63BTC的交易需要等待‘6’次比特币网络确认时间,而且需要支付‘6’次的比特币网络Gas费用和‘6’次以太坊上合约‘铸币’的Gas费。联想到现在以太坊被DeFi把Gas费已经助推到人神共怒的情况下,我很怀疑tBTC这样离散的设置能否实行下去,换句话说,如果坚持离散数值设置,基本可以‘劝退’大部分BTC跨链转账在1个BTC一下的用户了吧!而wanBTC因为采用的21个‘看门人’节点组的设计,所以只要在抵押物大于跨链交易金额的条件下,上面举例的1.63个BTC的交易会一次性完成,只需要1次BTC网络等待时间和1次以太坊上‘铸造’的费用。当然在‘看门人’组的抵押物不够该笔BTC跨链交易的情况下,机制设置就不会允许该笔交易完成以保证原生BTC资产的安全。另外一个两个机制的不同是合约交互的设置。因为不同的合约交互逻辑决定了跨链操作用户的等待时间和Gas费用支付。从用户角度来剖析:当转1个BTC到以太坊上的1个tBTC,用户需要发送的交易是1次BTC链的交易‘锁定’和2次以太坊上的合约交互:‘Request(请求铸币)’和‘Proof(锁定原生BTC后提交证明给合约)’;除此之外tBTC要为这笔交易‘选举‘不同‘签字人’组;等到‘签字人’组选举完成后他们再把BTC锁定地址发给用户。这样的用户等待时间会很长同时体验上欠佳。在Wanchain跨链机制中,当用户操作BTC到以太坊的wanBTC的情况下,由于Wanchain的‘看门人’组选举不是根据每次交易选择的,而是提前选举完成的,所以被选中的‘看门人’组会把锁定BTC的地址直接发给用户,就不需要用户去发送任何交易去以太坊。根据这些合约交互逻辑的设置,预测转tBTC会比wanBTC时间上多1–3倍(tBTC:离散的设置加两次以太坊交易),同时Gas费用支付多3–10倍(tBTC: Ethereum transaction fee *2 + Bitcoin transaction fee *1 + 0.005 BTC / Wanchain: Bitcoin transaction fee *1)。最后一点两个机制上的迥然之处在tBTC要求用户在6个月后必须‘赎回’其tBTC,而wanBTC没有这样的期限要求,用户可以在任意时间内持有wanBTC。这样‘奇怪‘的要求是因为在tBTC机制中,用户跨链完的tBTC是有单独选举出来的’签字人‘组来为其服务的,只要用户不把tBTC’赎回‘到BTC,这些’签字人‘节点就只能陪着用户等在那里,想退出也没法退出;所以tBTC强制用户最多6个月时间就要’赎回‘去;而wanBTC的’看门人‘组不是单独为某一笔交易服务的,同时’看门人‘节点组每次选举有节点退出,有节点加入,重新选举完成后,旧的‘看门人’组都会把‘账务’交接给新的‘看门人’组去:包括债务,责任和收益都转给了新的节点,故不需要强制用户在一定时间内’赎回‘映射的BTC资产。总体上评估,tBTC和Wanchain的wanBTC看出来都是认真思考‘去中心化’和‘安全’这两个跨链的核心维度上做突破,并做了大量研究工作和代码工程实现的务实工作。双方都采用了TSS最新的门限密码学研究成果,只不过因为取得门限值不同而带来其他一系列不同的设置从而引发了一些异同点。回到本文一开始所说的,现阶段没有一个跨链机制是‘100%技术‘上安全的,所以当引入了跨链节点的抵押品,经济惩罚和激励规则后,会是跨链这个区块链核心技术强有力的一个补充!这也是上篇分析文章中笔者提到的:更希望的是看到推动这个行业技术和应用往前更进一步的努力,而非只是靠’白皮书的理想‘来推动技术实实在在的发展!wanBTC和tBTC的对比分析 was originally published in Wanchain on Medium, where people are continuing the conversation by highlighting and responding to this story.

What is the Storeman ‘Activ...

What is the Storeman ‘Activity’ ?The goal of Storeman ‘activity’ is to prevent a node from being inactive for a long time and causing cross chain transaction to fail. So distribution of Storeman rewards is not directly related to the ‘activity’ of that node.2. The activity displayed on the Wanwallet and Wanchain explorer is calculated according to the activity factor of that node during the entire working cycle. Activity is caluated by the formula that: number of MPC signatures signed by that node divided / total crosschain transactions received by the Storeman group.3. The rewards are distributed on a daily basis. The rewards distribution is based on the overall activity factor but the activity of that day, which is calculated by MPC signatures signed by that node divided / total crosschain transactions received by the Storeman group of that day.The activity calculation of that day is the number of transactions signed by a certain node in the MPC that day divided by the number of cross-chain transactions received by the group that day.4. Check the activity of a day when rewards are distributed. If the activity is greater than or equal to 50%, there will be a full reward, and if the activity is less than 50%, there will be no reward.However, In order to avoid the occasional network problem of a node affecting the reward, the mechanism designed that when the total number of crosschain transactions throughout the day areless than or equal to 5, all nodes shall have full rewards regardless of the activity factor.What is the Storeman ‘Activity’ ? was originally published in Wanchain on Medium, where people are continuing the conversation by highlighting and responding to this story.

PoS DelegationNotes:You can view all current delegation information such as current and historical rewards and delegation actions for your accounts through the wallet interfaceThere is a 100 WAN minimum for delegationsHow to delegate — from the main screen:Staking →POS →Validators →Select a Validator →Delegate →Fill in delegation amount →SendPoints to watch out for:Quota Left: Check on the individual validator’s information screen that their “Quota Left” is more than the amount you wish to delegate. If it is lower than your delegation amount, you will need to choose another validator to delegate to in addition.Delegation Fee: The delegation fee is the percent of your delegation reward which is collected by the validator you stake to, a higher fee means lower rewards for you.After completing a delegation, you may modify your delegation or withdraw it from within the wallet interface.6. Storeman DelegationNotes:Unlike POS nodes, Storeman nodes have an election period during which you can delegate to a node, but delegators will not receive rewards at that time — check the Storeman node’s current status to see if you can currently earn rewards or not. If the node you delegate to is not chosen, then you may immediately remove your delegation and move it to a new node.Each Storeman group is limited to 21 nodes. Not every node is guaranteed a placement in the next group. Take note of when the “End Time” is in the Storeman node details page, and check at that time if your node successfully is enterned into the next group, or if the node fails and you must delegate to another Storeman node.You may delegate in at any time, but you may only remove your stake and earnings at the end of a Storeman group cycle. Check “End Time” in the Storeman details page, and make certain to withdraw before that time if you wish to withdraw that cycle’s deposit and rewards.How to delegate:From the main screen:Staking →OpenStoreman→Storeman→Select a Validator →Delegate In →Fill in delegation amount →SendFor technical support, please email techsupport@wanchain.org or contact one of the admins at the official tech support Telegram chat group: https://t.me/WanchainSupport.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

However, while it is still being loudly contested by Donald Trump it seems all but certain that Joe Biden will be the next POTUS. He intends to hire Gary Gensler as the financial advisor. Gary likes Bitcoin (1). Donald Trump does not like Bitcoin (1). Meanwhile Associated Press has published, on blockchain, their projection that Joe Biden will eventually be fully confirmed victorious (1). Official non-contestable results are expected within few weeks, after all the lawsuits and tweets settle. While most platforms decided to settle the ‘bets’ on who won the election costing Trump supporters cool $11 million (1), FTX exchanges has allowed until February 1st, 2021 for settlement (1). Other than that it has been a fairly quiet week; maybe except for a somewhat ‘accidental’ hard fork on Ethereum (and obviously some other more or less exciting stuff); nonetheless I hope you enjoy reading the reHash this week!NOTE:reHash is not intended to be original journalism. It is intended to be a brief summary of significant articles and events from the past week with links to the original sources. Sources will always be linked and credited.

Wanchain & Bitrue AMA Recap

All the questions an answers to the recent AMA with the Bitrue team and community!The AMA was held on November 12th, 10:00 UTC over on the Bitrue Official Telegram channelParticipants included:Jack Lu — Founder and CEO of WanchainLi Ni — Vice President of OperationsLiam — Wanchain Community ManagerQuestions and Answers1. Can you explain what decentralized crosschain technology is? What advantages does it have for regular users?Currently most of the existing crosschain solutions are centralized. One example is WBTC on Ethereum. The problem is user has to trust a centralized party for the crosschain assets. Wanchain’s cross-chain approach is to set up one or more decentralized wanBridges in order to connect blockchains. Each wanBridge is decentralized as a Storeman Group consisting of a number of Storeman Nodes. User now trust a network intead of a centralizef party to hold the cross-chain assets.” — Jack LuWith the rapid rise of blockchain technology, there are now thousands of public and private blockchains being used across the globe. However, these blockchains exist largely in isolation, unable to exchange information or value with one another. This severely limits their world-shaping potential. The purpose of a cross-chain solution is to connect different blockchains, like a bridge between islands. See the intro video here. — Li Ni2. Do you have a whitepaper so that we can do more research on Wanchain?Sure, you can find the whitepaper here and our yellowpaper here — all you want to know about Wanchain, including the WPs, tech details, Q&A, all here! — Li Ni3. You recently launched Wanchain 5.0. What improvements or additions are in this new version?WAN Bridges are Wanchain’s decentralized, universal solution for trustless and permissionless cross-chain value transfer. BTC, EOS, WAN, and more will be brought to Ethereum, and Ethereum assets will brought to Wanchain. We also made cross-chain transactions faster! — Jack Lu4. Has the COVID pandemic affected the development of Wanchain?I will say very little impact on us! just like now, Jack, Liam, and me, we three are in three different places! — Li NiVery little. Wanchain team has been global since the beginning and everyone is used to virtual conferences and online collabrations. Our dev team in China has to work from home for several months and some of our team members couldn’t travel during the pandemic but overall the impact was minimum. — Jack LuMost of our team continued to work remotely during this time, certainly didn’t have an affect on me! The team does an excellent job collaborating while working remotely as we always have — Liam5. What can be done with wanTokens?Okay, before answering wanTokens, let us see this situation in crypto. We have all been witness to the recent DeFi explosion, however that rapid growth has begun to hit some speed bumps. There are many reasons behind this decline, but one very important one is a lack of high quality assets on Ethereum itself. On Compound.Finance, there are only seven supported assets: BAT, DAI, ETH, USDC, USDT, wBTC and 0X. Among them, three of them are stable coins, and one is from another blockchain. This is despite the fact that there are over 10,000 other ERC20 tokens on Ethereum.This clearly illustrates the problem that Ethereum assets alone cannot sustain the DeFi ecosystem. Here at Wanchain we have anticipated this issue, and it is why we have spent the last 3 years developing a decentralized crosschain mechanism which enables native tokens on other public chains to swim into Ethereum DeFi in the form of wanTokens. The first wanTokens to launch on Ethereum will be wanBTC and wanEOS, and will soon be followed by wanXRP, wanDOT, and many more.This is what wanTokens! real decentralized, most secure, crosschain assets! — Li Ni6. Are there any similar projects to Wanchain? What do you do to stand out against them?Actually we think there’re no exact same projects in crypto as what Wanchain tries to do, for crosschain infra part, we can say Cosmos, Polkadot used to aim for this, but as their mainnets live, we actually found they kind of switching from crosschain to build themselves as a competitor to Ethereum. From crosschain tokens perspective, we have similar projects like Jack mentioned, those wrapped BTCs. But what Wanchain did with wanTokens, specifically wanBTC, is quite unique and different from those. I wrote two previous tech articles analyzing renBTC and tBTC, read here. — Li NiAnd some similiar ones like: tBTC, renBTC, pBTC. Wanchain is more decentralized and achieves better availability (fault tolerance), Wanchain is much more user-friendly and has a much lower cost. Wanchain’s TSS scheme is threshold optimal, which ensures high level of decentralization and security. — Jack Lu7. What kind of adoption have you seen on wanTokens so far?like i said, wanTokens such as wanBTC, wanEOS, wanXRP etc will greatly improve the diversity of assets to all defi applications. So far, wanTokens are based on the crosschain bridges. So wanchain just open the storeman crosschain node election right now, with the storeman group working, all these wanTokens will be created and can flow smoothly among all different chains! — Li NiRight now, we tested the wanTokens in our first defi ecosystem project: FinNexus. In future, we shall outreach to all those famous defi projects on Ethereum and other chains. One use case is what one of wanchain ambassdors suggested: Talk to Curve Finance to add a pair:wanBTC/WBTC. Compound may adopt wanEOS, wanXRP as underlying assets for the lending some day! — Li NiWe also just released a new version of our wallet making the crosschain process a lot easier and simpler to understand. The UI/UX has been greatly improved! — Liam8. Are there any upcoming wanTokens you can share the details of?Firstly wanBTC, wanETH, wanEOS and all other wanERC20 tokens will be live with the storeman established. The upcoming plan is to use crosschain to integrate more valuable assets! priority is wanXRP and wanDOT, bringing these two good assets to Ethereum!Given the demand for more high quality assets from other chains on Ethereum, we expect that quite a few DeFi protocols will beeager to include wanTokens into their system. We envision wanBTC and wanEOS being used as collateral on protocols such as Compound or Cream for lending and borrowing, and in asset pools on Curve or Swerve and many others. The inclusion of a diverse array of high quality assets from other chains would give any DeFi protocol a big competitive advantage.In a middle term, wanchain will open the crosschain framework so that all other chains use the framework to connect directly with other chains! So eventually, we wish we can help connect all chains and move assets freely in the network. — Li NiBringing all assets to Ethereum, one step at a time! — Liam9. Can you tell us about any community initiatives or events that you hold?For a start, we’ve got multiple AMAs planned across the crypto space, stay tuned for announcements on the when and where! We also introduced crewfire allowing users to earn some $wan for sharing our content on social media, join wanbrigade and help the Wandalorians spread the good word! You can sign up for Wanbrigade here, and check out the guide on how to participate here. — LiamWe’ll have AMAs, WanTalk shows, meetups… We also plan to work with partners on farming programs: FNX dual mining, WanSwap, WanLend, wanFarms@ethereum — Jack Lu10. Can you share some details about your future roadmap?In the coming days, with the official launch of Wanchain 5.0 mainnet, we will continuously launch brand-new and full series of cross-chain products over the course of the next few weeks, allowing users to experience the charms of Wanchain 5.0 cross-chain functionalities. Upgrades to the entire Wanchain product family are included:● WanWallet Desktop● WanWallet Mobile● WanMask● WanWallet Offline● Wanchain Explorer● Web Bridge● More surprises!For future roadmap, you can always check on our website: https://www.wanchain.org/learn/We released a new version of WanWallet Desktop on November 11th and beginning the public election of Storeman nodes this week. Stay tuned! — Jack LuIn the future, by establishing the decentralized Cross-chain Bank, Wanchain will provide global users with one-stop DeFi services that cover multiple scenarios and a full range of industries. Whether you are an institutional user or an individual user, you will benefit from Wanchain’s Cross-chain Bank. Everyone can be a provider of financial services as well as a customer of financial services. All traditional financial services such as lending, savings, financial management, payment, exchange, trading, etc. will be presented in a brand-new display on this decentralized and comprehensive Cross-chain Bank, and will continue to accumulate and burst out greater financial innovation. — Jack Luthe coming WanSwap, 1st crosschain swap AMM Dex. If you are interested, please follow WanSwap’s Twitter account. This is a pure community driven defi project. As the wanchain team, we keep giving this project necessary support. — Li NiIntroducing WanSwap — The Wanchain Based Cross-chain Decentralized Exchange With Automated Market…Some Notable questions from the communityQ — Do you take into account community feedbacks and demands?Yes we are constantly collecting feedback from the community and discussing it internally — LiamQ — Many projects launch campaigns to interact with users. Does $WAN finance have any specific plans to attract and grow the community or improve user experience?Sure, we got plenty marketing activities so maybe join Wanchain Telegram for details — Li NiQ — Today- New Collaborations & partnerships are very Important for the Growth & Developments of any Project Especially for CryptoProjects ! So- Can you tell us some Recent Major partnerships of $WAN for project Expansion & Future Plans?Sure, Jack answered that, please read up a bit to find the answer. We will pitch wanTokens to those big names in DeFi. — Li NiQ — Many people evaluate projects based on their token value, not the technologies/features the project possesses. How can your team add educational value to their investors so that more people understand your project than the price?Users often care less about technology, but rather the value of the token. How do you manage to strike a balance between developing the technology and also improving the value of the token?If you follow our medium you’ll see the team works tirelessly on explainer articles for our tech and products, we often do a series of deep dive articles covering our tech — LiamCorrect. Wanchain is trying always to balance the token price and tech advancement, we would love to hear more comments on that — Li NiQ — Sharding, layered, and cross-chain are the three future solutions for high-performance blockchains. $WanChain is currently at which direction? And what are the main reasons for taking this direction?Our direction is cross-chain for sure — Li NiQ — Being a pioneer of what we called cross-chain, do you see cross-chain protocols will become a standard in the future of blockchain?That’s what exactly we want to do! build a universal framework for cross-chain — Li NiQ —Working without clear goals can lead to the adoption of various strategies that are not working.A marketing department needs to have a well laid-out plan that outlines its short- and long-term goals. What are the project Marketing Department objectives?Totally agreed. We are working with external marketing consultants to come up with a good plan. Our current goal is to build awareness outside of our existing community. We’ll be working with other community for cross-chain collaboration. Most important thing is to increase adoption! — Jack LuQ — As Being permissionless, doesn’t this imply that any one can do anything on YOU ECOSYSTEM AND thus expose you to security threats, sybil attacks and 51 % attacks as recently ETC experienced 51 Attacks and they are permissionlessWe follow Multiparty computing so no 50% attack risk — Li NiQ — What are the $WAN plans to educate and raise awareness and adoption among the community to make more people understand about the project easily ?More marketing exposure, more AMAs, more media coverage — Li NiQ — How many projects have been built on Wanchain & what are the strongest points of your company that help to attract new investors on your network?A Whole Family of Cross-chain DeFi Dapps. Wanchain is actively investing in the development of a cross-chain DeFi ecosystem. Yesterday, we saw the release of FinNexus Options on Wanchain, which saw over $210,000 in digital assets contributed to its collateral pool within 24 hours. This is just the first DeFi-focused liquidity mining dapp to debut on Wanchain. More are coming in the next few weeks!We have launched our own Dapp Store. We have adjusted the gas price from 180 Gwin to 1 Gwin to better accommodate yield-hungry DeFi farmers. Our aim is to provide a sound ecosystem for developers, operators and ordinary users that maximizes the exposure of Wanchain Dapps, minimizes the cost of Dapp operation and maintenance, and enhances user experience. With the explosion of DeFi applications such as lending and farming, Wanchain community enthusiasts and partners have set their sights on this field. Many cross-chain DeFi dapps on Wanchain are poised to be released.The debut of Wanchain 5.0 makes it easier for the Wanchain community to launch a series of cross-chain DeFi dapps. Take a look at what’s on the horizon:WanSwap, a crosschain-based decentralized P2P trading platformWanLend, a crosschain-based decentralized lending platformwanToken Farm, a yield farming DeFi dappThese three dapps are just what we know are coming in the next few weeks! There’s no telling what our community of dedicated WAN Fans has been working on. Wanchain wholeheartedly welcomes partners and developers to develop Dapps and jointly promote the development and prosperity of the Wanchain cross-chain DeFi ecosystem. — Li NiBased on the feedback from our community, we have improved our UI and UX. We also developed many web based tools to attract more users — Jack LuQ — The market today has a lot of development projects on the Blockchain platform. One of the factors that makes the platform appealing to many users is its special features. So what are the outstanding features and advantages of $WAN to attract users and investors?Private transaction, decentralized cross-chain — Jack LuAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain 5.0 Desktop Wallet...

Wanchain 5.0 Desktop Wallet UpdatesThe newly updated wallet offers new features to support Storeman node staking and delegating functionalityIf you do not already have the newest version of the wallet downloaded and installed, please download the wallet, and follow this guide to install and set it up. Make sure to back up your wallet mnemonic phrase in a safe place (on paper, not any digital format).Update #1 — Updated Interface to Quickly Show Cross-chain SupportNow that Wanchain 5.0 has officially launched and we have begun transitioning from the old permissioned cross-chain bridges to the new permissionless and decentralized wanBridges, the Wallet UI has been updated to reflect these changes.The “Cross Chain” section has been updated to make it easier to navigate tokens from different wanBridgesNewly designed cross-chain token interfaceYou can see here that for each asset, the supported blockchain pair is listed if a wanBridge exists for that pair. For example, you can see here that the Bitcoin <-> Wanchain wanBridge allows for BTC to be swapped from the native BTC asset on the Bitcoin blockchain to WRC20 wanBTC on Wanchain (and vice versa, from wanBTC back to normal BTC), and also that there is another wanBridge connecting Wanchain and Ethereum. Using the Wanchain <-> Ethereum bridge, WRC20 wanBTC on Wanchain may be swapped for ERC20 wanBTC on Ethereum (and vice versa). The new UI makes it very easy to see at a glance which assets may be transferred to and from which blockchains.Update #2 — New Cross-chain Token Naming ConventionsThe new “@” based cross-chain token naming convention gives us a clear and logical way to refer to cross-chain assetsPreviously, the WanWallet did not have a is a developer naming convention which allowed users to understand which type of cross-chain assets they are transacting with a glance. The new “@” base naming convention makes it easy for anyone to quickly see which token they’re transacting with, and on which chain. The convention is simply described as such:“token symbol” @ “host blockchain”For example, ETH@Ethereum indicates the ETH token on the Ethereum blockchain, while wanETH@Wanchain indicates the Wanchain wrapped version of ETH (wanETH) on the Wanchain blockchain. wanETH@EOS would of course therefore indicate the Wanchain wrapped version of ETH on the EOS blockchain. As we add more wanBridges and as more and more blockchains become connected to each other, this naming convention will become increasingly important for rapidly and accurately distinguishing between asset formats.wanETH is now used instead of WETHYou can also see that W-tokens (such as WETH, WBTC, etc.) are no longer used in the wallet. This is due to the Swapdrop of W-tokens for wanTokens which was carried out this week as a part of the transition from semi-centralized cross-chain to totally decentralized cross-chain.Update #3 — Convenient Staking and Delegation Features for the New Storeman SystemDelegate easily to a Storeman node of your choice with one clickThe most important updates to the wallet for 5.0 make Storeman delegation and staking easy! As you can see from the screenshot, simply click the “New Delegation” button, fill in the details for the note you want to delegate to, and follow the on-screen instructions to get started delegating in less than a minute!Note 1: You may start delegating to a Storeman node at any time, but you may only remove your delegated WAN when the Storeman cycle ends. The first Storeman cycle starting from November 19th will last 49 days. The following Storeman cycles will last a entire calendar month each, so will vary from 28 to 31 days accordingly. The length of the cycle may be modified in the future, so please follow us on Twitter and Medium in order to stay up-to-date.Note 2: You may delegate WAN to a Storeman node before the node has been selected as part of wanBridge group, however, you will not begin earning rewards until AFTER the node has begun its work as part of the wanBridge.Register your Storeman node easily with the in-wallet interfaceIn addition to making delegation easy, the wallet also has functions that make it easier to get started as a Storeman node operator! As you can see in the screenshot, registration of a Storeman node is as easy as clicking a button!We are thrilled With the new possibilities that Wanchain 5.0 and wanBridges will bring to the world of DeFi! If you have any questions, comments, or suggestions, about the new WanWallet or any other Wanchain products, please get in touch. You can email Wanchain director of communication Noah Maizels at noah@wanchain.org at any time and we will make sure to get back to you!Wanchain is the infrastructure connecting the decentralized financial world.

The wanBridge Storeman Sele...

The wanBridge Storeman Selection Process Has Begun!Make sure to set up and register your Storeman node before the selection deadline of November 19th, 11:13am UTC+8Immediately following the release of the Wanchain 5.0 main net GWAN client on November 11, 2020, the Wanchain Foundation initiated the selection process for the first wanBridge. The first wanBridge will connect the Ethereum and Wanchain blockchains in order to empower bidirectional flow of assets between both chains.To learn more about how the Storeman node selection process, about how wanBridges work, and other Wanchain 5.0 features, check out our official 5.0 announcement article.For detailed step-by-step instructions about how to set up and register your node, please see this article.In order to support Storeman node operators, we have released a new version of the Wanchain desktop light wallet with a variety of new features which let node operators securely and conveniently perform important functions directly from their wallet. The new wallet makes it easy for you to get your Storeman node set up and to quickly register to take part in the node selection process.To download the new wallet and to learn more about all the new features it supports, check out the official release article.Storeman Node Selection Process:As we described in our 5.0 announcement article, each wanBridge connects a single pair of blockchains, for example, the first wanBridge to go live will connect Ethereum with Wanchain. The article also describes how each wanBridge consists of 21 Storeman nodes which permissionlessly operated by anyone who desires to participate. In order to decide which 21 Node operators are chosen to participate in a wanBridge, a selection process takes place prior to the start of the wanBridge. The selection criteria are very simple — the 21 nodes with the highest amount of WAN stake & delegation will be chosen to form the wanBridge.After being chosen to form a wanBridge, the 21 nodes must continue to work until the end of that cycle. Before the end of the cycle, node operators may choose to either join the next selection process, or withdraw and stop operating their node. The first cycle will be 49 days, with the following cycles each lasting a month.Each cycle has been named according to the Western zodiac. The first cycle has been named Aries_001.The First wanBridge Cycle “Aries_001” Details:NOTE: All of the below parameters are subject to change by the Wanchain Foundation. Over time, the control of such parameters will be turned over to public governance, however during this early period, the Wanchain Foundation shall control them to ensure the security and stability of the cross-chain mechanism.• Node selection time: November 10, 2020 16:13 to November 19, 2020 11:13 Beijing time, UTC+8• Node signature time: November 19, 2020 11:13 to November 21, 2020 11:13 Beijing time• Cross-chain node group working hours: Beijing time from 12:00 on November 21, 2020 to 12:00 on January 9, 2021• Delegation fee (percent of rewards paid by delegators to node operators): 10%• Cross-chain asset collateral ratio: 200% — For example, 2000 WAN may be used to generate 1000 WAN worth of wanBTC.• Delegation ratio: 1:1 — This ratio determines how much delegation a node is able to receive. A one-to-one ratio means that if a node has 50,000 WAN stake, then it can receive at most 50,000 WAN in delegations.About WanchainWanchain is the infrastructure connecting the decentralized financial world. Wanchain’s live cross-blockchain solution is EVM-based, includes optional private transactions, and provides a decentralized, permissionless, and secure approach for interoperability. Wanchain has employees globally with teams in China, the USA, and other team members around the world in Asia, Africa, and Europe.Website | Documentation | Telegram| Twitter | Newsletter | Blockchain Explorer | Developer PortalThe wanBridge Storeman Selection Process Has Begun! was originally published in Wanchain on Medium, where people are continuing the conversation by highlighting and responding to this story.

Wanchain 5.0 Mainnet Storeman Setup GuideA step by step guide for setting up a Storeman node on the Wanchain mainnet!!!!!! IMPORTANT NOTE !!!!!!Storeman registration runs from November 10th to November 19th, make sure you have registered by November 19th (Step 2.2)! Don’t miss your chance to make history as part of the first permissionless wanBridge!!!!!!! IMPORTANT NOTE !!!!!!Step 1) Download & Install Official Wanchain Desktop WalletWanWallet Desktop Download linkMake certain your seed phrase is backed up2. Storeman SelectionIn order to form a wanBridge, 21 Storeman nodes must work together. In order to choose which 21 nodes may form a wanBridge, there is a selection process based on the amount of stake in each node. The 21 nodes with the most WAN staked will be selected. In order to be considered for selection, node operators must register their node with a on-chain transaction.Summary of the Storeman setup process:Run scripts to obtain a Storeman Work Address , Public Key (your Storeman registration in WanWallet will be used), EnodeId String (your Storeman registration in WanWallet will be used), and back up the folder generated by the scripts.2.1 Generate Public Key and EnodeIDRun scriptsRename or delete osm if it already exists at /home/userwget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/envSetup.sh && chmod +x envSetup.sh && ./envSetup.shAfter you run the scripts above, there will be a folder osm generated at /home/user. The folder osm will be used when you start your Storeman node.Backup BOTH the script output and also the osm folder. If you are running these scripts locally, you will later need to copy the osm folder generated by these scripts to your cloud server.Note:The contents marked in bold will be used once you register your Storeman in WanWallet.!!!!!!!!!!!!!!!

This is the page for your Storeman to stake. Please transfer a small amount of WAN to your Storeman Work Address for gas fees which are required for your node to operate. The transaction will fail if the validator address has 0 WAN.B) Register as a Storeman CandidateAfter the Wanchain Foundation sends a transaction to begin a new Storeman Group, it will be visible in the Open Group List:Input the Public Key and Enode ID you generated by the previously run scriptSelect the account which you want to stake from and the amount of WAN you want to stake. After you confirm this information, you can see your staking details in the Storeman List.Add Additional Stake or Attract Delegations to Increase Selection ChancesAfter your Storeman becomes a Candidate, you can see the ranking of all Storeman Nodes, and top-up funds in theWanWallet.You can also accept delegations from individuals in order to increase your chance of getting selected.3. Check Selection Results, and Set Up Storeman Node if Selected3.1 Check Election ResultYou can check the Storeman selections results directly through the desktop wallet. If the status is Selected, it means that your Storeman node successfully entered the Storeman Group. If the Status is Not Selected, it means that your Storeman node failed to enter the group.The Storeman nodes which fail to be selected can claim back their WAN.3.2. Cloud Server SetupRecommended Specifications:A public IP without a proxy is required. Cloud and bare metal servers are both supported. The following table shows the requirements:Prepare Keystore and NodekeyIf you ran the setup scripts locally, please copy the Keystore and Nodekey files which were generated at /home/user to the same path on your cloud server. (See Section 2 for how to generate Keystore and Nodekey)3.3 Install Storeman Service:a) Transfer Small Amount of WAN to Work AddressDouble check you have already transferred a small amount of WAN to your Storeman Work Address for gas fees. The transaction will fail if the Storeman work address has 0 WAN.b) Environment Setup:Open Ports:Log in to your cloud server platform (such as AWS). Enable the following ports in the firewall inbound settings: TCP 37718/UDP 37718, and enable the following ports in the firewall outbound settings: TCP 26891/ TCP 26892/ TCP 30000. If you modify the ports of the scripts, please add the related port in your firewall.Initialize the environment:sudo chown $USER ~/osmrm init_open_storeman_EnvV3.shwget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/init_open_storeman_EnvV3.sh && chmod +x init_open_storeman_EnvV3.sh && ./init_open_storeman_EnvV3.shrm startStoremanV3.shwget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/startStoremanV3.sh && chmod +x startStoremanV3.shc) Configure KMSUsers can use shared key fragments through KMS. (It is highly recommended as it will greatly enhance the security of your funds).If you skip this part, you can go to Section d) Start Storeman Agent.Record the information listed below as you go throught the following steps:User Access key ID: AKIAJPUJ**********User Secret Access Key: KiHjz0g12a***********KMS Key Region: us-east-1KMS Key ID (ARN): arn:aws:kms:us-east-1: *****:key/*****AWS KMS SetupCreate an AWS user (mpc)Log in to AWS console and go to services.

CMKs are either customer managed or AWS managed. Let’s take a look at how to create a customer master key in AWS.Log in to AWS console and go to services. Then select “Key Management Service (KMS)”. On the left side you can see a section called “Customer managed keys”. Navigate to that section. Then select “Create Key” on top left.Follow the steps as follows:Please record the following two pieces of information from ARN (Amazon Resource Name):KMS Key Region: us-east-1KMS Key ID (ARN): arn:aws:kms:us-east-1: *****:key/*****d) Start Storeman Agentcd ~/osm/ ./startStoremanV3.she) Check Agent Container Statussudo docker exec -it openstoreman_mainnet pm2 lStatus of online and restart times of 0 represent normal status.View your log using following commands:# agent log sudo docker exec -it openstoreman_mainnet pm2 log 2 # mpc log sudo docker exec -it openstoreman_mainnet pm2 log 1f) Verify the connection number of Storeman PeersOpen mpc console through ipc, and check the number of connected MPC nodes in console:sudo docker exec -it openstoreman_mainnet ./schnorrmpc/bin/schnorrmpc attach ./schnorrmpc/data/gwan.ipc admin.peers.lengthConfirm the returned peer node information, which indicates the current number of MPC node connections. It should be more than 0.4. Storeman Group Running Period4.1 Top-up StakeDuring the Storeman Group working period, you can top-up WAN to your Storeman.4.2 Claim RewardsYou can claim your rewards every day. But the deposits can only be claimed when the entire Storeman Group period has concluded.4.3 ExitYou can choose to enter the next round or exit the selection process before the next Storeman Group is formed.You can top-up your staking amount at any time. ((Note: in the testnet, a cycle is 5 days, while in the mainnet, the first cycle is 49 days , following cycles will be 30 days— cycle time subject to change in future)After a cycle completes, you can claim your both deposits and rewards, and enter the next round.5. How To Delegate WAN To A StoremanFind the Delegation button:Click on New Delegation, and choose a Storeman to delegate to:You can also top-up WAN delegations to the same Storeman during the Storeman Group running period. You can withdraw your rewards each day. After a cycle completes, you can withdraw both deposits and rewards.Please note that the delegation amount to a Storeman can increase this Storeman’s weight. But the rewards will only be counted after the Storeman Group starts working.6.

Wanchain 5.0 Mainnet Is Liv...

Wanchain 5.0 Has Landed!!!The new Wanchain 5.0 client — Gwan 2.1.6 — is now live on the official Wanchain Github.On today, November 10th, 2020, the Wanchain team is proud to announce that Wanchain 5.0 Mainnet is live now!The launch of Wanchain 5.0 marks a landmark achievement in Wanchain’s cross-chain mechanism and cross-chain capabilites. Our cross-chain mechanism has been upgraded from semi-decentralization to a more perfect balance between decentralization and usability. Our Storeman nodes are now fully open to the community. Cross-chain capabilities are more affordable and scalable, allowing for native assets and tokens to flow securely and rapidly back and forth between any two chains connected by our wanBridges.The version of client Gwan for Wanchain 5.0 is v2.1.6.What Is Wanchain 5.0?Wanchain 5.0’s permissionless cross-chain solution perfectly balances decentralization with usability. Our decentralized wanBridges form the core of Wanchain 5.0, which ensures the safe and stable operation of the entire cross-chain system via the economic mechanism of staking WAN coins. Our wanBridges enable rapid and affordable cross-chain value transfer without compromising on security.Introducing the New Cross-chain wanBridgesLet’s take a look at the picture of Islands on the Ocean to illustrate Wanchain 5.0.In the vast ocean of cross-chain cryptocurrencies, there are floating islands, beautiful but isolated. Each island represents a chain. Due to the barrier of the ocean, those islands are isolated from each other. Reflected in the crypto world, there are countless different public chains, consortium chains, and private chains. Each has their own different underlying frameworks, data structures, and APIs. Therefore, connecting one chain with another chain, especially for heterogeneous chains (those with significantly different technical infrastructure), is a major challenge.In order to conduct regular business trading, people must build up cross-chain bridges between their two otherwise isolated islands. In the crypto world, those bridges are wanBridges that cross over from one chain to another. Eventually, wanBridges shall connect many different chains together. Each wanBridge represents a Storeman Group, which refers to a group of cross-chain nodes that secure a particular connection between two chains. Each Storeman node in the Storeman Group is like a solid bridge pillar, supporting the Storeman Group that monitors a particular bridge. At present, each wanBridge has 21 of these such pillars (i.e. 21 Storeman nodes) that, as a unit, secure the connection between two blockchains. These nodes represent actual Storeman node operators, who perform work to secure the chain and are compensated with fees denominated in WAN coins. Such pillars are costly for node operators to build up and maintain because they have to stake a minimum amount of WAN coins as deposit collateral. Currently, a minimum of 10,000 WAN coins are required in the current implementation of the Wanchain cross-chain mechanism.The Capacity of wanBridge Traffic Can Be Improved by Staking, Delegation and New wanBridgesHow to improve the traffic capacity between the two islands? The so-called capacity, to put it bluntly, is how to maximize the amount of assets that exist on-chain that can be transferred to another chain.There are two ways:Broaden the width of a wanBridge and increase the traffic capacity of this bridge. In the Storeman Group, each Storeman should strive to keep increasing its own WAN deposits to continuously widen the bridge. Meanwhile, Storeman node operators can attract WAN coin holders to delegate their WAN coins to the Storeman nodes, so as to further broaden the bridge by delegating more amount of WAN. In the current cross-chain mechanism design, the collateralization rate of the Storeman Group between Wanchain and Ethereum is 200%. In other words, for every 2000 WAN pledge, it allows the amount of crosschain assets up to a value of 1000 WAN worth of WAN, ETH or ERC 20 tokens to traverse the WAN-ETH wanBridge.Build up a new wanBridge between the two islands to increase the traffic capcity. In other words, a new Storeman Group can be established for the two chains. The operating mechanism of this Storeman Group is consistent with the previous Storeman Group. The bridge can be widened by more staking and delegation amount of WAN coins.Mechanism Guarantee of Wanchain 5.0Why does the water in the ocean not seep into the earth? Because there is an undersea crust and mantle that hold up the vast ocean. In the cross-chain ocean, the whole set of cross-chain mechanism runs smoothly, safely and efficiently because the economic mechanism and security mechanism embedded in Wanchain 5.0 have the same effect on cross-chain assets as the crust and mantle has on the ocean.Economic Mechanism GuaranteeOverall rewards design:No cross-chain service fee (temporarily subsidized by Wanchain Foundation)Incentive paid to cross-chain Storeman Node operators who run nodesIncentive paid to delegators who contribute stake to Storeman nodesTotal Storeman reward is limited with a hard cap to ensure that the high rate of return doesn’t cause too large an amount of funds to move away from Proof of StakeIn Wanchain 5.0, cross-chain bridges are built and run by groups of Storeman nodes. Storeman operators stake a security deposit in order to ensure honest behavior. Delegators may contribute additional stake to Storeman nodes in order to increase the cross-chain asset transfer limits and share in network rewards.Secruity Mechanism GuaranteeWanchain applies different threshold signature schemes (TSS) according to the technical structures of blockchain systems. For blockchain systems that do not support smart contracts (such as Bitcoin), we apply the ECDSA TSS scheme. For blockchain systems that support smart contracts (such as Ethereum and EOS), we apply the Schnorr TSS scheme. Wanchain 5.0 vastly improves the underlying TSS schemes, which ensures the security and decentralization of the whole system.Wanchain 5.0 adopts a consensus-based method to verify cross-chain information. Based on the idea of “signature is consensus,” we combine the verification of cross-chain information with the management of locked accounts. Specifically, a Storeman node verifies the cross-chain transaction first on the original chain locally, then generates a corresponding signature share, and afterwards sends to the destination chain. Once the number of signature shares exceeds the two-thirds (2/3) threshold, it means that the Storeman nodes, working as a Storeman Group, have reached consensus on that cross-chain transaction. At the same time, these signature shares are constructed into the complete signature, thus triggering the generation and release of the cross-chain assets on the chain at the other end of the wanBridge.Wanchain 5.0 Cross-chain Products FamilyWith the official launch of Wanchain 5.0 mainnet, we will continuously launch brand-new and full series of cross-chain products over the course of the next few weeks, allowing users to experience the charms of Wanchain 5.0 cross-chain functionalities. Upgrades to the entire Wanchain product family are included:WanWallet DesktopWanWallet MobileWanMaskWanWallet OfflineWanchain ExplorerWeb BridgeMore surprises!We wil release a new version of WanWallet Desktop on November 11th and beging the public election of Storeman nodes this week. Stay tuned!A Whole Family of Cross-chain DeFi DappsWanchain is actively investing in the development of a cross-chain DeFi ecosystem.

Chapter 3: Wanchain 5.0 Cry...

Chapter 3 of the Wanchain 5.0 deep dive article seriesBy Wanchain’s Chief Cryptographer and designer of Galaxy Consensus, Demmon ZhongIntroductionThere are two fundamental problems to be solved in any cross-chain solution, one — how to lock and manage cross-chain assets, and two — how to verify cross-chain information. Wanchain 5.0 solves these two problems in a decentralized way using cryptographic techniques. In this article, we will introduce Wanchain 5.0’s solutions to these two problems and their advantages compared to other existing solutions.Management of Locked Cross-chain AssetsOverview of Options for Managing Locked Cross-chain AssetsThere are three commonly used methods for locking cross-chain assets, protocol-based methods, multi-signature based methods, and Multiparty Computation with Threshold Signatures Scheme (MPC / TSS) based methods. Wanchain makes use of a MPC / TSS based method.Compared to other methods, it has the following advantages:Universal — It is applicable for any blockchain system without changing underlying mechanismsEfficient — Only one valid signature is needed to control the locked account, which reduces storage and computationFlexible — it allows any number of nodes to control the locked account and is adjustable to suit different needsWanchain applies different TSS (threshold signature schemes) according to the technical structures of blockchain systems. Specially, for blockchain systems that do not support smart contracts (such as Bitcoin), we use an ECDSA TSS scheme. For blockchain systems that support smart contracts (such as Ethereum, EOS), we use a Schnorr based TSS scheme. Wanchain 5.0 includes major upgrades to our previous TSS schemes, which ensures the security and decentralization of the whole system.Wanchain 5.0’s Improved Threshold-optimal ECDSA TSSWe will first explain the concept of “threshold optimal”. Generally, in a (t,n) TSS scheme, there is a total number of nparticipants, of which t participants are required to generate a valid signature. “Threshold optimal” indicates that t can range from 1 to n, i.e. t∈[1,n]. The ECDSA TSS scheme most commonly used by blockchain projects is from tjepaper “Robust Threshold DSS Signatures” published in 1996. This scheme is not threshold-optimal, for t∈[1,(n+1)/2]. Because in this scheme, the secret key is divided into secret shares by Shamir secret sharing. When performing the MPC multiplication operation in the signing process, degree of the polynomial which shares the multiplication result will increase to 2t-2. The formulae are as follows:s denotes the secret key, f(x) denotes the polynomial used to share s, r denotes the nonce in ECDSA scheme, g(x) denotes the polynomial used to share r. In the signing process, shares of s multiplicate with shares of r. Then F(x) is the polynomial that shares sr, of which the degree is 2t-2. So in order to recover sr, the least number of participants is 2t-1, which should be less than n:Then we know t∈[1,(n+1)⁄2].Wanchain 5.0 employs the latest research into ECDSA TSS schemes to improve our cross-chain solutions for Bitcoin. Our ECDSA TSS scheme is from the paper “Fast Multiparty Threshold ECDSA with Fast Trustless Setup” published in 2018, which uses homomorphic encryption and the MtA (Multiplication to addition) protocol to ensure the solution is threshold optimal. The property of threshold-optimal is vital to any cross-chain solution’s security and stability. We discuss this in two aspects:When t is fixed, regular ECDSA TSS schemes require no less than 2t-1 participants working together to generate a valid signature. But for threshold-optimal ECDSA TSS scheme, only t participants are required. For example, assuming 5 participants are enough to reconstruct the private key. Then in regular ECDSA TSS schemes, in order to generate the valid signature in the way of MPC, the secret key has to be spread to at least 9 nodes. If the adversary succeeds in attacking 5 of the 9 nodes, then he is able to reconstruct the secret key and steal the assets in the locked account. But in threshold-optimal ECDSA TSS scheme, the secret key is spread to 5 nodes. The adversary has to attack all of the nodes successfully to steal the assets in the locked account. To make a summary, when t is fixed, the secret key has a wider spread in regular ECDSA TSS schemes than threshold-optimal ECDSA TSS scheme, which raises the risk to be attacked. So threshold-optimal ECDSA TSS scheme is more secure.When n is fixed, in regular ECDSA TSS schemes t∈[1,(n+1)⁄2], but in threshold-optimal ECDSA TSS scheme t∈[1,n]. So the range of t in threshold-optimal ECDSA TSS scheme is almost one time bigger than that in regular ECDSA TSS schemes. When t=(n+1)/2, the valid signature cannot be generated in regular ECDSA TSS schemes if one of the nodes is offline. But in threshold-optimal ECDSA TSS scheme, the valid signature can always be generated as long as the number of offline nodes is less than (n+1)/2. So threshold-optimal ECDSA TSS scheme has the property of fault-tolerance and is more stable.Improve Shamir secret sharing to Feldman verifiable secret sharingWanchain applies Schnorr TSS scheme in blockchain systems that support smart contract. Compared to ECDSA TSS scheme, Schnorr TSS scheme has less computation consumption and fewer interaction rounds, which improves the efficiency of managing locked account. Wanchain 5.0 opens all the Storeman nodes to community, so a precise slashing mechanism is needed to punish the malicious nodes to ensure the security of cross-chain process. The basis for such a slashing mechanism is a method to verify the validity of data sent during the TSS signing process. So we improve the original Schnorr TSS scheme by replacing the Shamir secret sharing with Feldman verifiable secret sharing. After the improvement, any node can verify the validity of its data received from other nodes. One the data is invalid, the node can upload it to a special smart contract, which will verify the data and punish the corresponding sender.Solution To Verifying The Cross-chain InformationThere are two ways to verify cross-chain information — proof-based methods and consensus-based methods. In proof-based methods, the sender of cross-chain information has to provide an extra proof to prove the validity of the related cross-chain information. In consensus-based methods, a group of nodes consensus on the cross-chain information, of which the result determines the validity of the cross-chain information. Wanchain 5.0 adopts a consensus-based method to verify the cross-chain information. Based on the idea of “signature is consensus”, we combine the verification of cross-chain information with the management of locked account. The Storeman node verifies the cross-chain transaction in the original chain locally, generates the corresponding signature share, and sends to the destination chain. Once the number of signature shares exceeds the threshold (such1/2, 2/3 ), it means that the Storeman nodes have reached consensus on that cross-chain transaction. At the same time, these signature shares are constructed into the complete signature, which triggers the cross-chain assets generation and release. Compared to the proof-based method, our solution is user-friendly because of the fact that users have to send only one single transaction, which reduces cost and time.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

[Updated on 11.05] Progress of Wanchain 5.0 Testnet: Release Of Test Version of Web Bridge, A Web Cross-chain ToolUpdated on November 5th, 2020Release of Test version of Web BridgeWeb Bridge is a web cross-chain tool in Wanchain 5.0 product series. With Web Bridge, users can rapidly convert cross-chain assets between Wanchain and Ethereum based on the decentralized WAN Bridge mechanism.Web Bridge (for testnet only):http://34.210.227.55:8000/We highly recommend you use MetaMask and WanMask together when you use Web Bridge.WanMask (for testnet only):http://wanchain.org/download/wanmask-chrome-3.0.0.zipNote that all the products above are only for the Wanchain 5.0 testnet. Please DO NOT transfer your mainnet WAN coins to those products at present.Brief Guide of Web BridgeOpen Web Bridge URLWeb Bridge: http://34.210.227.55:8000/Currently, Web Bridge only supports Chrome.Click Start after the home page opens.2. Select Cross-chain Assets PairIn the Cross-chain Assets Market, find the cross-chain assets pair that you want to convert. Click Convert to go to the next.Currently, we only support “Wanchain <-> Ethereum” cross-chain pairs. More cross-chain pairs on other public chains will be added in the future. You can choose a specific pair in the drop-down list on the top-right corner.3. Connect Plugin Walleta) Connect WanMaskDownload WanMask http://wanchain.org/download/wanmask-chrome-3.0.0.zip;In the Chrome browser, find More tools -> Extensions;Drag and drop the WanMask zip file to the Extensions page;Open WanMask, and follow the guide to generate a new WAN address;Connect your WanMask.Note that this zip file of WanMask is just a temporary version and only for the testnet. Once the official version of WanMask goes live, you can search and find WanMask in the Chrome Extensions Store.b) Connect MetaMaskSearch and find MetaMask in the Chrome Extensions Store, and Add to Chrome;Open MetaMask, and follow the guide to generate a new Ethereum address;Connect your MetaMask.4. Cross-chain Transfer OperationsAfter the two plugin wallets are connected, you can start cross-chain transfer. In the Convert page, you can see the cross-chain assets pair you chose and the cross-chain asset direction, as well as the original and targeted addresses conntected to the wallets.You can re-select the cross-chain assets pair. You click the Arrow icon to reverse the cross-chain direction;Choose a proper Storeman Group according to the Quota;Input the amount of assets that you want to cross-chain transfer, and click Confirm;Double check your cross-chain transaction information. Click Start or Approve once you confirm. (If it is the first time for you to transfer the asset, you have to make an authorization to the wallet. After the authorization is successful, you can click Start);In this case, Web Bridge will try to connect your wallet. Either WanMask or MetaMask will pop up and wait for your approval;After that, the cross-chain transaction will be recorded on chain. You will soon receive your cross-chain assets just waiting for a few minutes;Check the cross-chain assets transaction status and wallet connection status in the information center at top-right corner.5.

Chapter 2: Economic Incentives

Chapter 2: Storeman Economic Incentives & SlashingIntroductionWanchain 5.0’s economic incentives serve two primary purposesFirst, community members are rewarded to act as Storeman nodes building bridges to provide the cross-chain functionality. Second, malicious behaviors are punished by slashing bonded stake.CHANGES FROM PREVIOUSLY ANNOUNCED REWARDS MECHANISM:Before digging into the details of the reward and slashing mechanism, please note that several previously announced incentives details have been changed:The Stake to Delegation ration has been changed from 1:5 to 1:1The MPC cycle length has been changed from 3 months to 30 daysThe delegation fee has been modified from 5% to 10%Minimum stake for a Storeman node is 10k WANRewardsThe basic principle of the Storeman rewards mechanism is that Storeman operators expend resources and take risks in order to ensure the smooth and secure operation of cross-chain transactions. Delegators contribute stake to storeman nodes, and are thus also rewarded.Overall designNo cross-chain service fee (temporarily subsidized by Wanchain Foundation)Incentive paid to cross-chain Storeman Node operators who run nodesIncentive paid to delegators who contribute stake to Storeman nodesTotal Storeman reward is limited with a hard cap to ensure that the high rate of return doesn’t cause too large an amount of funds to move away from Proof of StakeThe total reward of the Storeman system is defined by this formula (this is the sum of the rewards paid out to ALL storeman from all bridges combined):r₁ = r₂ × αr1 denotes reward rate of PoS consensus, r2 denotes reward rate of crosschain, and αdenotes zoom coefficient. In the initial stage, we set α=1.5, which means the average reward rate of crosschain is 1.5x that of PoS consensus. At present, r1=7.67%, so we have r2=11.5%.Second, to achieve a balance between cross-chain reward and PoS consensus reward, we set a hard cap for cross-chain daily reward asHardCap = PoSDRHardCap is the maximum daily rewards for the Storeman system, and PoSDRdenotes PoS dail rewards. At present, HardCap=6027 WAN.Assuming the total deposit for crosschain is w, then crosschain daily reward CDRis computed asFrom the above formula we know, as wincreases, CDRgrows linearly. When itreaches 19.1 M, CDRequals 6027 WAN and remains unchanged.The cross-chain reward rate r2is 1.5 times PoS consensus reward rate r1before CDRreaches hard cap. When CDRreaches the hard cap, r2decreases linearly as wgrows. Finally, r1=r2, when w=28.6M WAN.In summary, the cross-chain reward rate is higher than the PoS consensus reward rate in the initial stage, which encourages the development of the cross-chain ecosystem. As cross-chain deposits grow, the cross-chain reward rate decreases due to the hard cap. An equilibrium will be reached when the cross-chain and PoS reward rates are equal.Reward division between Storeman and delegatorsIn Wanchain 5.0, cross-chain bridges are built and run by groups of Storeman nodes. Storeman operators stake a security deposit in to ensure honest behavior. Delegators may contribute additional stake to Storeman nodes in order to increase the cross-chain asset transfer limits and share in network reward.sAs described above, r2is the crosschain reward rate, which is the average of the Storeman’s reward and thedelegator’s reward. As for reward division, Storeman operators earn more due to node operation costs.w1is the Storeman node deposit, w2denotes the deposit of delegators, Fr denotes the delegation fee rate, and μdenotes the weight. Storeman daily reward(CDRs) and delegators’ daily reward(CDRd) are calculated asStoreman’s reward rate rsand delegators’ reward rate rdare calculated asAssuming w1=2M, w2=10M, Fr=5%, μ=1.5, then we know CDR=3780, rs=18.57%, rd=10.08%Activeness Index of Storeman NodesTo evaluate the activeness of Storeman Pi’s participation in the cross-chain process, the activeness index is defined as:n denotes the total number of cross-chain events in Storeman Pi’s work cycle, mdenotes the number of crosschain events which Pi participates in.Besides, we set a threshold τfor Storeman’s activeness index. Storeman will not get reward if its activeness index is below τ. Assuming Storeman Pi has a deposit of ws, then its reward Ris calculated asSlashingOverall designTo ensure security and reliability, malicious behaviors will be punished by the slashing of stake.The slashing mechanism detects Storeman’s malicious behaviors in a decentralized way without the need of any trusted third party. Specifically, in the keygen stage, Storeman nodes exchange data with each other on chain. Invalid data will be detected by a challenge / response process, which takes the on-chain data as input. In the signing stage, a enhanced version of Shamir’s secret sharing is used with the inclusion of Feldman’s VSS protocol. Any Storeman node is able to verify the validity of the received data. The invalid data will be uploaded to the smart contract to trigger the slashing process. In summary, the detection of malicious behavior is based on on-chain data and smart contracts. So it is publicly verifiable and ensures the correctness and fairness of theslashing mechanism.Malicious behaviors and the corresponding slashing methodsAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain 5.0 wanToken WETH ...

All WETH & other wrapped ERC20 tokens on Wanchain will automatically be swapdropped sometime between November 6th and November 10th next weekWhat is the Wanchain 5.0 Swapdrop?With the launch of Wanchain 5.0, the Wanchain cross-chain Storeman bridge will change from a permission one managed by the Wanchain foundation to a permissionless one managed by the public. Previously, the Wanchain foundation Storeman nodes issued wrapped Ether as WETH and various wrapped ERC20 tokens as W-Tokens (WETH, WLINK, WMKR, WZXC, WUSDT, WTUSD, WGUSD, WUSDC, WEURS), on Wanchain. With the launch of the new permissionless Wanchain 5.0 Storeman bridges, a new set of wrapped tokens must be issued. Those tokens are known as wanTokens. In order to get all Wanchain users their new wanTokens, we will take a snapshot (an exact record of the blockchain at a single point in time) of Wanchain at some time between November 6th and November 10th, and will in the next few hours airdrop an equivalent 1:1 amount of wanTokens to all WETH and wrapped ERC20 token holders.Do Not Transact Your Old WETH or Wrapped ERC20 Tokens from November 6th to November 10thIn order to prevent malicious behavior, we are not revealing the exact time that the Swapdrop will take place, rather we are telling users that it will take place at some point between November 6 and November 10. So we recommend that users do not transact with their tokens at all between November 6th and November 10th, in order to ensure that they receive the correct amount of wanTokens.What About my Old WETH and Wrapped ERC20 Tokens?After the Swapdrop, you will no longer be able to use your old WETH and wrapped ERC20 tokens to convert back to their corresponding tokens on Ethereum. However, you will have received the corresponding wanTokens in the Swapdrop which you will be able to use to withdraw back to the native corresponding token on Ethereum. The old WETH and W-Tokens will not have any value, so please be careful not to mix up the new wanTokens (wanETH and wanERC20s) with the old and valueless WETH and W-Tokens.Example:For example, let’s say that you have currently 5 WETH and 100 WLINK in your wallet. Starting from November 6th, you should not do any transactions with those assets. Sometime before November 10, you will be airdropped 5 wanETH and 100 wanLINK. Once you receive your airdropped tokens, you will then be able to start using your new wanTokens.Stay tuned to our Medium and Twitter to learn more about what you can do with wanTokens after 5.0 launches!About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Chapter 1: Overview of Wanc...

Wanchain 5.0’s WAN Bridges — Enabling a New World of Interoperable DeFiHere at Wanchain we’re quite fond of using the metaphor of Wide Area Networks vs Local Area Networks (“WAN vs LAN”), to describe the incredible potential which will be unleashed when the crypto industry’s currently mostly isolated blockchains and their assets finally become connected. In the early days of the internet, knowledge was siloed in local university and library LAN networks. The advent of WAN, which connected all of those local networks in order to form the incredible network of knowledge and data which is the internet as we know it today, unleashed an incredible torrent of creativity, new businesses, new financial opportunities, even entirely new cultures and ways of life. It is in fact from this metaphor that Wanchain takes its name — WAN+chain.Wanchain’s goal is to unleash the incredible power of connectivity by building the infrastructure for the universal connection of all blockchains and their assets. What WAN networks did for data and knowledge, we predict Wanchain’s cross-chain infrastructure will do for decentralized financial applications (DeFi).For the past several years Wanchain has been building the infrastructure to power cross-chain DeFi use cases in a decentralized and trustless way. Our ultimate goal is not ONLY to connect various blockchains and digital assets together, but also to connect the world of decentralized finance together with traditional finance and assets. This new world where value flows freely from blockchain to blockchain, and between DeFi and traditional ecosystems, and where trustless applications can be built to take advantage of all this different interoperable value, will be just as revolutionary as step forward as the introduction of the global Internet.Lack of Standardization Leads to “Value Islands”As unglamorous and dry as rules and standards may seem at first, there is a certain magic to them which gives them great transformative power. We can see examples of the power of standardization over and over through history.In 221 BC, the Chinese Emperor Qin Shihuang conquered his six neighboring nations to establish the Qin Dynasty. After firmly establishing his rule, Emperor Qin set about enforcing the standardization of currency, weights, measures, transport system and the writing system.Prior to Emperor Qin’s enforcement of standards, each local area had their own individual standard, and some places would even mix multiple standards together! Take for example the seemingly simple and rudimentary technology of horse carriage tracks. These were not the modern roads or cast iron train tracks of later years, but were rather simply furrows set in the earth at a set width apart. Before the unification of Qin Dynasty, the width of the carriages used by the six nations was different from each other, resulting in the different widths of the tracks. Therefore, it was extremely inconvenient for the carriages to go from one country to another. After standardizing the transport system, goods could be transported from one place to another more efficiently and conveniently, which allowed for the entire domain which was using the shared track standard to share in the economic benefits it brought.The situation of track widths prior to the Qin dynasty is mirrored in the world of blockchain today. There are countless different public chains, consortium chains, private chains each with different underlying frameworks, data structures, and APIs. Therefore, connecting one chain with another chain, especially for heterogeneous chains (those with significantly different technical infrastructure), is a major challenge.The Phenomena of Value Islands Limits the Potential of DeFiDue to the lack of standards, the phenomena of “value islands” has arisen. Value islands refer to the different assets and applications which operate on various different blockchains, and cannot easily connect with other different chains. The most obvious example of this is of course that of Ethereum. While it is true that a number of real world assets and assets from other chains have been issued on Ethereum through a variety of mechanisms with different levels of security and decentralization, the value island problem is still very severe. Only a select few assets are able to find their way to Ethereum from elsewhere, with USD stable coins and BTC pegged or backed tokens are the most prominent of these. Aside from these few assets, next to none are able to find their way onto Ethereum. Not only is it difficult for value get onto the Ethereum island, it’s just as difficult for it to leave! While there may currently be some experimental solutions for bringing ETH to other chains, none are currently widely used or accepted.This brings us to the peculiarly lopsided DeFi market as it has evolved today. The DeFi ecosystem in the public chains represented by Ethereum is prosperous, while DeFi ecosystem in other more public chains are cared by few people. We have counted the top 40 DeFi projects on CoinMarketcap. You may get a general whole picture of DeFi world from those top 40 DeFi projects.Billions of dollars worth of assets are trapped on other blockchains, unable to participate in the recent DeFi boom on Ethereum.WAN Bridge — Wanchain’s Decentralized, Universal Solution for Trustless and Permissionless Cross-chain Value TransferSince the publishing of our whitepaper over 3 years ago, our focus has stayed set on building infrastructure for cross-chain value transfer in order to enable new decentralized financial use cases. After years of intense research and development, engineering breakthroughs, and lots of blood, sweat, and tears, the Wanchain team is about to unveil the product which realizes many of the primary goals which were laid out in the original whitepaper — The WAN Bridge.The introduction of WAN Bridges allows for assets to begin to flow freely between different heterogeneous blockchains, despite the lack of standardized blockchain infrastructure.WAN Bridge Development HistoryIn 2018, Wanchain successfully implemented a cross-chain value transfer solution which allowed BTC, ETH and ERC20 tokens to move back and forth from their native chain to Wanchain. In 2019, Wanchain integrated with EOS and proposed a universal cross-chain framework protocol T-Bridge for cross-chain integration with consortium chains.2020 bring us to Wanchain 5.0 and the WAN Bridge. The WAN Bridge is a major step forward from our previous cross-chain implementations in practically every important dimension including decentralization, trustlessness, and security. Most prominent of these advances is that WAN Bridges are universal which means they allow for the transfer of value back and forth between any two connected chains.WAN Bridge is the core product of Wanchain 5.0, and is a major upgrade based from our previous cross-chain mechanism. It is an affordable and scalable solution which allows for native assets and tokens to flow securely and rapidly back and forth between ANY two chains connected by a bridge.First Ethereum…and then the World!As each pair of chains to be connected requires its own bridge, WAN Bridges will be set up one by one after the launch of Wanchain 5.0, starting with the most prominent public blockchains, and eventually expanding to include a large array of popular public blockchains. Naturally, the first bridge to be set up will connect Wanchain with Ethereum. Through this bridge, Wanchain’s native WAN and WRC20 tokens may travel back and forth between Wanchain and Ethereum. Likewise, the bridge also allows for ETH and ERC20 tokens to flow freely back and forth between the two chains.A Note on Nomenclature:One of the unique challenges brought by cross-chain asset transfer is that of taxonomy. As more and more tokens become available on more and more different chains, the problem arises of how to refer to the various cross-chain formats of the same asset. We have proposed our own nomenclature for cross-chain tokens using the @ symbol and lowercase token symbol prefixes.“@” nomenclature:The “@” symbol is used to specify which blockchain a token currently resides on. For example, WAN@Ethereum refers to the ERC20 version of the native WAN asset which as been issued on Ethereum.Lower case token symbol prefix nomenclature:This nomenclature is used to specify which service provider has issue a cross-chain token. For example, wanETH refers to the native ETH asset which has been issued as a wrapped token by Wanchain. It DOES NOT specify which chain the token resides on. In order to do that, we would need to combine the nomenclatures. For example, wanETH@Wanchain refers to tokens on Wanchain, while wanETH@EOS would refer to the same underlying tokens, only now on the EOS blockchain.Regarding the naming rules of cross-chain assets, we will have a more in depth discussion in future articlesWanchain 5.0 Cross-chain System’s Foundational Concepts:RolesWanchain 5.0’s Cross-chain system includes a variety of different actors who fill different roles in the system. Below is a diagram summarizing the different roles:These various roles and their functions will be discussed more uflly in later articles.Cross-chain value transfer core mechanismWanchain’s cross-chain approach is to set up one or more decentralized WAN Bridges in order to connect blockchain pairs. Each Wan Bridge has a Storeman Group consisting of 21 Storeman Nodes (node which manage the cross-chain value transfer process).Security MechanismIn order to ensure the safe and stable operation of the entire cross-chain system, Storeman Node operators must pledge a certain amount of collateral to be put up as stake. Meanwhile, node operators can also attract deposits from partners and delegators to increase their total stake and obtain more rewards during node operation.Future articles will cover staking, delegation, and the rewards from each in greater depth.WAN Bridges uses a threshold signature scheme combined with multiparty computation (TSS + MPC) in order to guarantee the security of the locked assets and the smooth functioning of the cross-chain value transfer system.Cryptoeconomic incentives are also used to guard against malicious behavior. Node operators are required to over-collateralize the value of the cross-chain assets they issue. In cases of malicious behavior, that collateral may be slashed. In this way, the cost of malicious behavior is greater than the rewards set to be gained by it, so we can ensure that node operators are always incentivized to behave honestly.Incentives and slashing will be discussed in greater detail in a future article.Wanchain 5.0 HighlightsWAN Bridges are Wanchain’s decentralized, universal solution for trustless and permissionless cross-chain value transferBTC, EOS, WAN, and more are brought to Ethereum, and Ethereum assets are brought to WanchainThe first decentralized cross-chain bridge from EOS to EthereumWhere we go from here…Our long term goal is the establishment of a distributed cross-chain bank which will provide global users with a one-stop shop which decentralized financial products to fulfill all their needs.Our long term goals will be discussed in greater depth in a future article.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain 5.0 Open Beta Test...

The Wanchain 5.0 Testnet will be fully open for public testing on September 30th, 2020.Wanchain 5.0 Testnet Bounty Program:https://medium.com/wanchain-foundation/wanchain-5-0-testnet-bounty-program-a820162ee030Wanchain 5.0 Testnet Bug Report:https://forms.office.com/Pages/ResponsePage.aspx?id=VPnN3XSIEEqLYwFUDjqIlk-ycC0AzHBFlOYMrVpv55NUNEU1QktDWkMyUlE0TElSTkZFWjU1TUpUUC4u1. Background KnowledgeThe cross-chain mechanism of Wanchain actually builds a WAN Bridge between two public chains, so that assets on one chain can be integrated into another chain, and vice versa. At the core of a WAN Bridge is a Storeman Group connecting two public chains. Each Storeman Group is a WAN Bridge, and each Storeman Group contains 21 Storeman nodes.The entire workflow of a Storeman Group is as follows:For a cross-chain transfer user, you don’t need to fully understand the whole process of the Storeman Group. The most important part for a cross-chain transfer user is 05, that is, Storeman Group running period. You can cross-chain transfer your coins and tokens such as WAN, wanBTC, wanEOS, Link, FNX to Ethereum, and cross-chain transfer ETH from Ethereum to Wanchain.2. Download Official Wanchain Desktop WalletDownload official Wanchain Desktop Wallet test version for Wanchain 5.0 Testnet, and generate a WAN address to receive WAN test coins.Note: please don’t send your mainnet WAN to this test version of WanWallet.Download linkhttps://www.explorewanchain.org/#/wallet_and_tools/wan-walletNote: Considering the compatibility issue between the new and the old wallets, we highly suggest you backup and reset your wallet and clear local data.Please ensure that you have backed up the seed phrase of your previous wallet.If the wallet fails to start up, it is receomended to rename the folder Wan Wallet as a backup, and then restart your wallet. Take Windows 10 as an example:Go to Open Data Folder from your WanWallet menuGo back to the folder Roaming, and rename the folder Wan WalletFinnally, restart your wallet.3. Apply For WAN, Test CoinsFor cross-chain transfer users, we provide a couple of test coins application website where you can apply for small amount of those test coins, such as WAN, FNX, BTC, ETH, EOS, LINK etc.Websites for test coins application:WAN and FNX:https://wanchain-faucet.vercel.app/BTC:https://bitcoinfaucet.uo1.net/send.phpETH:https://faucet.rinkeby.io/EOS:http://monitor.jungletestnet.io/#faucetLINK:https://rinkeby.chain.link/4. How to Cross-chain Transfer Coins & TokensIf you are a cross-chain transfer user, you would like to transfer WAN from Wanchain to Ethreum, here is the operationsGo to Cross Chain>WAN>Wanchain<->Ethereum. It means that you want ot cross-chain transfer WAN to Ethereum or transfer WAN on Ehtereum back to Wanchain.Click on Convert, key in crosschain related parameters, and complete WAN coins cross-chain transfer from Wanchain to Ethereum or vise versa.By default, the wallet ony displays WAN and ETH crosschain. If you want to cross-chain transfer with other coins, you have to make them enable, such as BTC, EOS, LINK, FNX.

Wanchain 5.0 Testnet will be fully open for public testing on September 30th, 2020.Wanchain 5.0 Testnet Bounty Program:https://medium.com/wanchain-foundation/wanchain-5-0-testnet-bounty-program-a820162ee030Wanchain 5.0 Testnet Bug Report:https://forms.office.com/Pages/ResponsePage.aspx?id=VPnN3XSIEEqLYwFUDjqIlk-ycC0AzHBFlOYMrVpv55NUNEU1QktDWkMyUlE0TElSTkZFWjU1TUpUUC4u1. Background KnowledgeThe cross-chain mechanism of Wanchain actually builds a WAN Bridge between two public chains, so that assets on one chain can be integrated into another chain, and vice versa. At the core of a WAN Bridge is a Storeman Group connecting two public chains. Each Storeman Group is a WAN Bridge, and each Storeman Group contains 21 Storeman nodes.The entire workflow of a Storeman Group is as follows:In short, for a Storeman, you need to pay attention to the whole workflow. You should register a Storeman, try your best to be among the top 21 Storeman nodes so as to enter the Storeman Group, provide cross-chain services in the Storeman Group running period, and finally decide whether to enter the next round of Storeman node elections before the Storeman Group is dissolved.Key parameters: For the first Storeman Group cycle, you can prepare from September 30th to October 8th. If you are selected into the Storeman Group, you have to set up your server between October 9th & 11th. The Storeman Group will be running form October 11th to 16th. We plan to complete three cycles during Wanchain 5.0 Testnet.2. Download Official Wanchain Desktop WalletDownload official Wanchain Desktop Wallet test version for Wanchain 5.0 Testnet, and generate a WAN address to receive WAN test coins.Note: please don’t send your mainnet WAN to this test version of WanWallet.Download linkhttps://www.explorewanchain.org/#/wallet_and_tools/wan-walletNote: Considering the compatibility issue between the new and the old wallets, we highly suggest you backup and reset your wallet and clear local data.Please ensure that you have backed up the seed phrase of your previous wallet.If the wallet fails to start up, it is receomended to rename the folder “Wan Wallet” as a backup, and then restart your wallet. Take Windows 10 as an example:Go to Open Data Folder from your WanWallet menuGo back to the folder Roaming, and rename the folder Wan WalletFinnally, restart your wallet.3. Apply For WAN Test CoinsFor Storeman nodes, we provide a WAN test coins website where you can apply for a large amount of WAN test coins. The applicant must register his/her information, and answer 5 questions related to Wanchain. According to the number of correct answers, WAN test coins will be randomly distributed to your WAN address, ranging from 10,000 WAN to 100,000 WAN. The more questions you answer correctly, the greater number of WAN test coins you will get.Website for large amount WAN test coins application:https://storeman-form.vercel.app/You will immediately receive WAN test coins ranging from 10,000 WAN to 100,000 WAN after you submit the application form online.4. Storeman Nodes’ Staking & CompetitionFor the Storeman nodes who participate in the election, only top 21 Storeman nodes with biggest staking amount will be selected. Considering the cost of cloud servers, you can run the scripts in your local Linux Operating System to obtain a Validator Address (transfer your WAN test coins to this address to automatically participate in the Storeman node election), Validator Public Key (your Storeman registration in WanWallet will be used), EnodeId String (your Storeman registration in WanWallet will be used), Keystore JSON String (copy the contents to the same path of cloud server after the cloud server starts), and Nodekey String (copy the contents to the same path of cloud server after the cloud server starts).If you already have a cloud server you can use, you can run the scripts directly on the cloud so as to reduce the step of copying files from local machine to the cloud server.4.1 Generate Public Key and EnodeIDRun the scripts in LinuxRename or delete the folder osm if it has already existed in the path /home/userwget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/envSetup.sh && chmod +x envSetup.sh && ./envSetup.shAfter you run the scripts above, there will be a folder osm generated in /home/user. The folder osm will be used once you start establish your Storeman node.Back up the script outputNote:The contents marked in Bold will be used once you register your Storeman in WanWallet.!!!!!!!!!!!!!!!

The transaction will fail if the validator address has 0 WAN.Become a Storeman CandidateWhen Wanchain Foundation sends a transaction to begin a new Storeman Group, you can see what Storeman Group that is available to receive what staking amount in the Open Group List.Input your Public Key and Enode ID you generatedSelect the account which you want to stake from and the amount of WAN you want to stake. After you confirm this information, you can see your staking details in the Storeman List.Top-up your Storeman CandidateAfter your Storeman becomes a Candidate, you can see the ranking of all Storeman Nodes, and top-up your funds to your Storeman in WanWallet.5. Setup Storeman Node5.1 Check Election ResultYou can check the Storeman election result in the wallet. If the Status is Selected, it means that your Storeman node successfully entered the Storeman Group. If the Status is Not Selected, it means that your Storeman node failsed to enter the group.The Storeman nodes which fail to be selected can claim back their staking funds.5.2. Setup Storeman Node on CloudHardware RequirementsTo setup a Storeman node needs independent public IP. You can use cloud service or setup your own server. Linux OS is recommended. The following table is the minimum requirements of AWS for your reference.Prepare Keystore and NodekeyPlease copy the files of Keystore and Nodekey which were generated in the path of /home/user of your local machine to the same path of your cloud server. (See Section 5 for how to generate Keystore and Nodekey)5.3 Install Storeman ServiceInitialize the environmentOpen PortLog in Storeman management platform.

Storeman Group Running Period6.1 Top-up Staking AmountDuring the period of Storeman Group working, you can top-up WAN to your Storeman.6.2 Claim RewardsYou can claim your rewards every day. But the deposits can only be claimed when the entire Storeman Group completes.6.3 ExitYou can choose to enter the next round of electoion or exit the election before the next round of Storeman Group starts.You can top-up your staking amount at any time during the cycle of Storeman Group operation. (Note: in the testnet, a cycle is 5 days, while in the mainnet, a cycle is 45 days, up to current rule).After a cycle of Storeman Group completes, you can claim your both deposits and rewards, and enter the next round of election.7.

Wanchain 5.0 Testnet User G...

Wanchain 5.0 Open Beta Testnet Bounty Program: Guide for DelegatorsWanchain 5.0 Testnet will be fully open for public testing on September 30th, 2020. We really appreciate friends all over the communities to take part in the test of Wanchain 5.0 Testnet.Wanchain 5.0 Testnet Bounty Program:https://medium.com/wanchain-foundation/wanchain-5-0-testnet-bounty-program-a820162ee030Wanchain 5.0 Testnet Bug Report:https://forms.office.com/Pages/ResponsePage.aspx?id=VPnN3XSIEEqLYwFUDjqIlk-ycC0AzHBFlOYMrVpv55NUNEU1QktDWkMyUlE0TElSTkZFWjU1TUpUUC4u1. Background KnowledgeThe cross-chain mechanism of Wanchain actually builds a WAN Bridge between two public chains, so that assets on one chain can be integrated into another chain, and vice versa. At the core of a WAN Bridge is a Storeman Group connecting two public chains. Each Storeman Group is a WAN Bridge, and each Storeman Group contains 21 Storeman nodes.The entire workflow of a Storeman Group is as follows:For a delegator, you don’t need to fully understand the whole process of the Storeman Group. The most important part for a delegator is 02 and 05, that is, Storeman nodes competition and Storeman Group running period. Similar to PoS, you can choose one of your trusted Storeman and delegate your WAN to this Storeman. The minium amount of WAN for a delegator is 100 WAN. Note, if a Storeman node which are not in the group at present, you will not receive rewards when you delegate WAN to this node.2. Download Official Wanchain Desktop WalletDownload official Wanchain Desktop Wallet test version for Wanchain 5.0 Testnet, and generate a WAN address to receive WAN test coins.Note: please don’t send your mainnet WAN to this test version of WanWallet.Download linkhttps://www.explorewanchain.org/#/wallet_and_tools/wan-walletNote: Considering the compatibility issue between the new and the old wallets, we highly suggest you backup and reset your wallet and clear local data.Please ensure that you have backed up the seed phrase of your previous wallet.If the wallet fails to start up, try renaming the folder “Wan Wallet” as a backup, and then restart your wallet. Take Windows 10 as an example:Go to Open Data Folder from your WanWallet menuGo back to the folder Roaming, and rename the folder Wan WalletFinnally, restart your wallet.3. Apply For WAN Test CoinsFor delegators, we provide a WAN test coins application website where you can apply for small amount of WAN test coins.Website for small amount WAN test coins application:https://wanchain-faucet.vercel.app/You will immediately receive 200 WAN test coins.4. How To Delegate WAN To A StoremanSimilar to the delegation mode in Wanchain Galaxy Consensus, as a delegator, you can delegate your WAN to a Storeman in WAN Bridge. Here is the way:Find the Delegation button:Click on New Delegation, and choose a Storeman to delegateYou can also top-up your WAN to the same Storeman during the Storeman Group running period. You can withdraw your rewards daily. After a cycle completes, you can withdraw both deposits and rewards.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Say Hello to Wanchain’s DAp...

To mark the addition of the official DApps section to the Wanchain home page at: https://www.wanchain.org/dapps/, we present this overview of the most prominent DApps in the Wanchain ecosystem.In this article you can find an overview of the DApps which are currently available on Wanchain. You can use Wanchain DApps directly in your Chrome or Brave browser with the WanMask web wallet, the WanWallet desktop light wallet or the WanWallet mobile app for iOS and Android.Jack’s Pot — The Wanchain based, no loss lottery by Wanchain and FinNexusWant to participate in a lottery without losing your funds? We have a DApp for you! Jack’s Pot is a DApp where you can buy lottery tickets for 10 WAN each. The staked WAN is delegated to a Wanchain validator and generates rewards as a part of the consensus process. The rewards are then pooled together in a single pot and awarded to the lottery winners. Your tickets will be automatically taken into the next round, however you can withdraw them at any time you want. One round lasts a single week and if there are no winners the rewards will be taken to the next round.Wandora Box — A decentralized price prediction game by Wanchain and FinNexusWandora Box is a simple game where you can win prizes by predicting the price trend of WAN/BTC over a set period of time. Any user who predicts correctly will win a prize. As a fun additional twist, all users who make a prediction will be enrolled in a lottery where they have a chance to win another prize, regardless of whether or not their prediction is correct. Wandora Box issues prizes every 8 hours.WRDEX and Bitlly DEX — Cross-chain decentralized exchangesTwo decentralised exchanges have been Built on WanDex. WRDEX (Wanchain RiveX decentralized exchange) and Bitlly DEX (Bitllywood) allow users to trade Bitcoin, Ethereum, EOS and many ERC-20 and WRC-20 tokens. More assets will be listed in the future when Wanchain implements more blockchains on their cross-chain solution. They both offer fast transactions (2000+ p/s), are easily accessible and allow you to trade directly via the web portal, mobile wallet and the Wanchain Light Wallet. All DEXes built on WanDex share a liquidity pool to offer a smoother trading experience.Red Packet — Gift WAN to individuals or groupsThe name “Red Packet” comes from the Chinese traditions of giving money in red envelopes at festivals and special occasions. Wanchain now brings this tradition into the world of blockchain! You can generate a Red Packet code with a set amount of WAN and send it to an individual or a group without knowing their address in advance. There is even an option to create a referral Red Packet which rewards users for sharing the code. Red Packet is exclusive for the mobile WanWallet for Android and iOS.FinNexus options — Write, trade and exercise options with pooled liquidityFinNexus Options is an inferface that runs on FPO (FinNexus Protocol for Options), this is a decentralized, permissionless and non-custodial protocol for writing, trading, and exercising options. All the functions of options are deployed on smart contracts.FPO 0.1This beta protocol was launched on Wanchain. The options in FPO 0.1 are tokenized options that give the holders the right, but not the obligation, to buy or sell underlying crypto assets at a specified price (Strike Price) at expiration. It’s integrated through a WRC20 smart contract. With the v0.1 model, options writers issue each option individually, and make profits or losses according to the market performance of each option they issue.FPO 1.0v1.0 introduces the innovative Multi-Asset Single Pool (MASP) model for decentralized options. Under this model the option writers contribute liquidity to a single monolithic pool from which all options are generated. In this way rewards and risks are shared proportionally amongst all liquidity providers. FPO 1.0 will also add the Ethereum blockchain When FPO 1.0 launches (3rd or 4th quarter 2020) it’s mechanisms will benefit both liquidity pool contributors and options buyers/traders.More information on the differences between FPO 0.1 and FPO 1.0 can be found here.DApp LinksJack’s Pot — No loss lottery from FinNexusWandora Box — Crypto price prediction gameWRDEX — Decentralized cross-chain exchangeBitllywood Dex — Decentralized cross-chain exchangeRed Packet — Send crypto as a giftAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

Cross-chain ETH-WAN Bridge ...

We first announced Wanchain 5.0 with its Wanchain to Ethereum cross-chain bridge less than two months ago in our mid year update article. Since then, Wanchain’s R&D team including several of PhDs in cryptography & other related disciplines, and our over thirty skilled software engineers have been working non-stop to bring Wanchain 5.0 to fruition. The fruits of their labor are now here and open to the world with the launch of the Wanchain 5.0 cross-chain bridge on Ethereum’s Rinkbey Testnet.On August 26, 2020, the Wanchain R&D team successfully deployed the Wanchain 5.0 cross-chain bridge prototype on the Ethereum Rinkeby testnet. The bridge now enables the cross-chain transfer of testnet WAN between Wanchain’s testnet and the Ethereum Rinkby testnet.This technology is now live on the testnets of Wanchain and Ethereum. This means that WAN from the Wanchain testnet can now be securely sent to the Ethereum testnet, and back.You can check out the ERC20 WAN token on the official Rinkbey Tesntet Explorer site.What is a Two Way Cross-chain Bridge?A cross-chain bridge is a mechanism which allows for assets to flow back and forth between two different blockchains. Wanchain’s first version of a cross-chain bridge first launched about two years prior allowed for a one directional flow of assets from other chains on to Wanchain. With the launch of Wanchain 5.0, these bridges will be upgraded from one way to two way. While previously the WAN-ETH bridge only allowed for ETH and ERC20 tokens to be transferred from Ethereum to Wanchain, the new two way bridge also allows for WAN and WRC20 tokens to flow the other way on to Ethereum.Cross-chain Powered by Wanchain’s MPC & TSS Enabled Storeman NodesWanchain’s two-way bridges are powered by a group of nodes referred to as Storeman Nodes. When working as a group, those nodes are referred to as a Storeman Group.As we discussed in our earlier article digging into renBTC’s current implementation of their ETH-BTC cross-chain bridge, MPC & TSS (multiparty-computation and threshold secret schemes) play a major role in guaranteeing the security of cross-chain bridges. In short, this technology allows for a large group of nodes to securely and collectively manage the process of moving value back and forth between different chains. In this prototype testnet bridge we have set the group number to 21 nodes, and have set the threshold number at 16 (for more information about “threshold” numbers, MPC & TSS, check out the articles linked to at the start of this paragraph).Rapid Cross-ChainFor the upcoming Wanchain 5.0, we are introducing a new rapid cross-chain cross-chain method. This method has already been completed successfully on the testnet. In prior versions of Wanchain’s cross-chain bridge, the cross-chain process required multiple steps starting with the Storeman cross-chain node group initiating the cross-chain request on the source chain. After initiating the request on the source chain, the user must then also perform a redeem transaction on the target chain.With the new rapid cross-chain mechanism, that redeem step is no longer required. Rather, an initiator on the source chain can directly send tokens to an address on the target chain without any redeem transaction required to confirm receipt.Compared with the previous cross-chain method based on hash time locks (HTLC), the rapid cross-chain method greatly shortens the cross-chain transaction time (no need to wait for the user to redeem), and greatly reduces the cross-chain cost (reduced by two on-chain interactions) At the same time, it also greatly reduces the difficulty of the cross-chain operation and improves the cross-chain transaction experience.One downside to the rapid cross-chain method is that it is a little less secure than the old method, and so may not be suitable for large transactions. For transactions which require higher security, the old HTLC version is still available, and we encourage users to use it for high value transactions.Examples of HTLC cross-chain transactions on Rinkeby:https://rinkeby.etherscan.io/tx/0x9267c7f276f5f0318715611491e3e4feba4405227079da2aa5c2cf74bf09e3d6#statechangeExamples of rapid cross-chain transactions on Rinkeby:https://rinkeby.etherscan.io/tx/0xf126a3117cd08fc188ddd09b381a34cc4c1d74bd8712cd47cc412c2a7bc805e1#statechangeOf course, our cross-chain research does not stop at two-way bridges. In addition to the two-way bridge and fast cross-chain features, we’re very excited about the development of what we have been referring to as “direct” bridges. In a follow-up article, we will introduce “direct” bridges in detail, and explain how they differ from previously discussed bridges.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

August 2020 AMA

Thank you for all your questions! We read and discuss every single question and consult with all relevant team members to get the best answer for each question before publishing.This AMA features answers from:Wanchain Founder & CEO Jack LuWanchain Director of Communications Noah MaizelsWanchain VP of Operations LiniQUESTION: Michael Scofield — When will be the first STO launch on wanchain platefarm? What is the most excited daps which is in the progress? Can you guys shed a light on what decisions went wrong for wanchain and we could do better ….and what we learn from those. How are we improving ourselves from past? ANSWER:We have successfully integrated with a STO platform, however there is not currently large market demand for STOs. We integrated the STO framework so that we will be ready to go if market trends change and STOs change to become in high demand. If that happens, we’re already ready to go, and don’t need to spend any time playing catch up. With how quickly things tend to change in this industry, it’s important to follow that old boy scout motto, “Be prepared”! Rather than one particular blockchain, we are most excited about all the DApps which will be able to use our cross-chain assets on Ethereum after the launch of our two-way bridge allowing Ethereum DApps to use all the assets currently circulating on Wanchain, and many more assets from other soon to be connected blockchains.From our launch back in 2017 we were initially quite inward focused. We were focused on building Wanchain itself, connecting other blockchains to Wanchain bringing their value to Wanchain, and on promoting the building of DApps on Wanchain. While we have had a number of very important accomplishments based on this strategy including the development of our cross-chain storeman technology and our original PoS mechanism, Galaxy consensus, we’ve now realized that we need to be more outwards looking. Going forward we will continue to develop the core Wanchain technology and ecosystem, but we will also place a greater focus on connecting with the greater DeFi world on other blockchains where most of the DeFi activity is. Our ultimate goal is to allow for the value from assets of any blockchain or even real world asset to be used on any other blockchain. — Jack, Noah, & LiniQUESTION: Andrei — Do you have a plan to put bitcoin, ethereum and others in stake on Wanchain to increase the volume of storemans? (Rewards in Wan) ANSWER:We have had numerous discussions on this and the current thinking is that we can easily set up a multi-asset collaterral pool on Wanchain to accept pre-approved assets. The issue is how to distribute the rewards fairly. Of course we do welcome other partners such as connected chains or projects who are willing to provide additional rewards to the collaterals. If we do implement multi-asset collateral, we will make certain to design the economic incentives in a way which incentivizes validators to use WAN vs other collateral. We recognized there is value in having multi-asset collateral since it lowers the volatility and therefore risk of the system, but at the same time, we want to ensure that the system brings value to WAN and to the Wanchain ecosystem, so the emphasis will be on incentivizing WAN as collateral. — Jack & LiniQUESTION: user : c — Does it still make sense to continue integrating other blockchains, it looks like eos integration is a completely failure and no one cares about it and no usage at all. Is it still wise to allocate resources to chain integration? When will redefining finance happen (ReFi) wan proposed 3 years ago? After 3 years we saw red pocket, lottery dapp and that’s not very redefining to me, more of a kids game, you might have bigger plan but community needs to know. ANSWER:In terms of integrating additional blockchains, It’s a chicken and egg problem when it comes to building cross-chain Defi. We need to continue to improve the cross-chain mechanism but at the same time we need to integrate as many blockchains as possible. We always ask our community to contribute as which chain to integrate first but certainly some blockchains are more valuable than others. We are building the infrastructure and will continue to support our partners to build more Dapps to help on user adoption. In terms of the other part of your question, we have recently made some big changes in our business and development strategy addressing that, see the answer to question one for a description of that. You can also reference our 2020 roadmap LINK update article for a more in depth answer to how our strategy is changing going forward — JackQUESTION: My last question for this month is for @jackxlu, as the CEO, you are the front people of wanchain and should be promoting wan whenever however you can and be enthusiastic about wan, l know your are an humble person but it seems there is not much Twitter activity. Do you plan to increase your Twitter exposure? ANSWER:Certainly. It’s difficult to use Twitter in China but I’ll try my best to increase my Twitter exposure. — JackQUESTION: cchenae | Eden validator — How large is the dev team? I do not see much dev activity that matches the rumored 40 devs. I checked both wanchain and wandevs GitHub. The main wanchain updates are sporadic, maybe only 3–4 devs are working on the core code base. Also there are almost no contributions from devs outside wanchain team. What are the plans to attract more devs? Any hackthons etc?ANSWER:We currently have a little over 30 devs, the number of devs changes somewhat according to our development load as well as market conditions. Most of our development activities are on our private repositories. While we are strong advocates of the open source philosophy, we don’t want to release our code before it’s ready for production and give our competitors a head start on us. For that reason we typically do not release code publicly until it is near production ready state. The majority of the infrastructure has been built by our core team but we do welcome partners and community developers to build Dapps on Wanchain. We have a dev portal and will offer more bounties to attract more devs. We also are working with Mousebelt to train more devs in universities and organize more hackathons. — Jack LuQUESTION: Over the years, wanchain has announced many partnerships. Are there any projects that wanchain is work on with the partners? It does give me (and many others I believe) the impression that partnerships do not mean anything at the moment. Also, correct me if I am wrong, wanchain 4.0 has no follow ups after about half a year and the code base looks like abandoned. I wonder who actually audited the codes. The was supposed to be the “big thing” of wanchain right? I am really confused about the tactics. The team seems to be doing things without putting users in mind. This also goes to the dexes. Nowadays I don’t think there are serious use. Will the team (not the robot) themselves use the products? ANSWER:Like in any organization, business development activities open a lot of doors and bring us more growth opportunities. But for various reasons, some partnerships might end up with less valuable while others show lasting, long term results. Some of our long term partnerships which continue to bring benefit to the Wanchain ecosystem include Band Protocol, with whom we have cooperated in a variety of different ways, and who is currently working with Wanchain ecosystem project FinNexus to provide oracle data on Wanchain for use in their decentralized options platform, FPO. Another project we have cooperated with since 2018 will soon have a major integration going live on the Wanchain mainnet, stay tuned to our social media for more news. ChainLayer is another excellent long term partner of Wanchain who has provided multiple valuable contributions to our ecosystem including WanMask, MyWanWallet, has made major contributions to our WanDevs developer community, and is also operating a PoS stake node. There are many other partners who provide us with value in one way or another which might not be associated with any particular technology or product release, and so are not very visible to the public. As for 4.0, we built a reference implementation for the public chain to private chain integration and released a T-Bridge integration framework which brough us a lot of business opportunities. We strongly believe that the blockchain will show the greatest value once the crypto world gets connected with the real world. But certainly we are in the early adoption stage, so some of the trials might fail. We’ve recently added efforts and resources to our efforts to promote Wanchain 4.0 for use in enterprise solutions. Our new VP of Business Development Steven He is primarily focused on enterprise blockchain opportunities using Wanchain 4.0 as well as Wanchain’s other public and private chain based solutions. He is specifically focused on Chinese government institutions, state owned enterprises, and large corporate entities. — Jack & NoahDELETED account — Hello. First thank you for this great opportunity and taking your time for community. I would know, how is WANChain actually positioned on marked? Wan was many times compared with ETH, but actually eos/ trx and eth have many dApps, how looks on wan? Thank you and regards. ANSWER:We envision Wanchain complementing rather than competing with Ethereum. It can provide a number of vital solutions to current issues plaguing the Ethereum DeFi ecosystem including a truly trustless cross-chain bridge, a solution for ballooning transaction fee costs, and for applications which can take advantage of Wanchains 1000+ TPS and private transactions. Unlike some other interoperability focused projects such as Cosmos and Polkadot which aim to connect with other blockchains of similar infrastructure, Wanchain aims to enable transfer of value between multiple blockchains with arbitrarily different infrastructures including chains such as EOS, Bitcoin, Ethereum, Wanchain, and in the future with the XRP ledger, Cosmos, and Polkadot based chains. — NoahQUESTION: Alitoshi K. — Any idea about solving the liquidity issue around wanchain coin… it seems the token lacks of liquidity in major exchanges… Can you please give an explanation how the team looks at this problem… thanks Any improvements for mobile wallet? many mobile wallets there in the space are doing very nice functions easily and friendly with great design… just look at some and navigate them to get ideas to improve wanchain mobile wallet. wanchain deserves high quality products in everything.ANSWER: WAN liquidity is currently adequate for most of our users, and is in the millions of dollars daily volume several major exchanges. Moreover, after the launch of the upcoming Wanchain 5.0 with the two way bridge allowing for value transfer from Wanchain to Ethereum (and back) of ERC20 based WAN, along with other ERC20 versions of Wanchain assets such as wanBTC and wanEOS. This means that WAN will be tradable on Uniswap and other popular AMM (automated market making) based decentralized exchanges which have attracted very large trading volumes as of late. If liquidity truly does become an issue, we always have the option of using liquidity mining to incentivize WAN liquidity providers on Uniswap and other AMM DEXes. However we do not think that will be necessary as we expect the volume on Uniswap and similar AMM DEXes to be quite high. As for the mobile wallet (and the desktop wallet as well), we are currently working on upgrading the UI and UX. However as the Wanchain 5.0 release with 2-way bridge to bring multiple chain’s assets to Ethereum is our current top priority, the UI/UX updates are not our current top priority. — Jack & LiniQUESTION: Panzer Wagen — i wonder when eth 2.0 — + ren/any other direct bridges on eth to — btc/eos …- i wonder what will be usage of wan native chain — if there is any point to waste resources on building it — or just to move into crosschain solution and make second layer on eth with tip-top infrastructure. Wouldnt this be the better way? why do you think there should be wan blockchain ? what is the point there from your side? ANSWER:We have debated about this many times since the beginning of the project. When Wanchain was first built, we knew that we needed to have a scalable blockchain which could serve as a hub for multiple other chains. At the time, Ethereum had the most developed ecosystem, however it was too slow and expensive to be useful as a cross-chain hub. Moreover their development cycle was too slow to allow us to build the solution we required. At that time, blockchain frameworks such as Polkadot’s Substrate and Cosmos’s Tendermint were not yet developed enough to be viable choices for us. We therefore chose to begin as an Ethereum fork so we could both take advantage of their ecosystem of tools and knowledge while also allowing for a great deal of flexibility in our development direction.Of course we are constantly evaluating and researching new technology which may benefit the Wanchain blockchain and ecosystem. We are always open to adopting any technology which would further our goal of connecting value and defi use cases between multiple chains. However, any major changes to Wanchain’s main chain infrastructure would mean a large amount of development effort, time, resources, and would probably require a hard fork, so we will be very careful and do a great deal of research and planning before taking any steps in that direction. — Jack & NoahQUESTION: foorex — i am curious what kind of business/process framework wanchain uses? there are many out there like extreme programming, scrum and derivates of that. i saw thalium developing with lean and scrum. Would be cool to see how you guys manage the processes. Were there any benefits for announcing a partnership with chainlink besides the usecase? since finnexus uses band protocol like binance, does chainlink oracles the centralized site ANSWER: The dev team uses a version of the Agile framework, and uses the ZenTao project management tool. The team is flexible in their implementation of the Agile framework, following many general Agile principles while also using some of their own development practices. — Noah (by way of dev team)QUESTION: adam eve — Question for @jackxlu Would it be possible to give the core ambassadors some more workingspace and a little more freedom to start the initiatives they enthusiastically put their time and effort in? It now feels a bit like most of the things they would like to start, keep getting overruled or blocked. I dont think such things have to be perfect right from the start. I think its more important to start the initiatives (and improve on the way) so they can start engaging and growing the wanchain-community. ANSWER: We are very open to ambassadors starting their own initiatives, and every single month multiple such initiatives are going on such as meme competitions, helping with BD, helping with social media and content creation, etc. We have a very active community including the ambassador program and otherwise who regularly contribute.

How Safe Are Today’s Wrappe...

The question of the security of wrapped BTC bridges has been a simmering concern throughout the DeFi community for a long time. Ethereum founder Vitalik Buterin himself highlighted the issue in a recent tweet:The comments under his post were filled with heated debate from members representing all different corners of Crypto Twitter. Various existing mainstream bridge solutions such as those from Republic Protocol (REN) and Wanchain (WAN) were brought up.From my research into secure cross-chain technology as part of my work at Wanchain, I have a good general understanding of various cross-chain BTC mechanisms. Lets take a look at just exactly how they work and why people use them:The How…The simplest and most straightforward understanding of BTC cross-chain bridges is that a user transfers “real” BTC to an address on the Bitcoin blockchain where it is locked. After this address receives the “real” BTC, it will mint a “fake” ERC20 BTC on Ethereum. This type of token is known as a mapping token or a “wrapped” token, and is freely usable as a representation of BTC on Ethereum. When going the other direction, the ERC20 BTC is burned (destroyed), and the locked BTC on Bitcoin is released. ERC20-based BTC tokens minted on Ethereum are prefixed with a symbol to indicate the protocol or organization behind the cross-chain bridge. For example, wanBTC, renBTC, sBTC, WBTC, tBTC, etc.The general process for moving BTC from its own native Bitcoin blockchain and back again is described by this simple 2-step process.The Why…In essence, when minting wrapped BTC, “real” BTC is exchanged for “fake” BTC. Some might ask, why would I want to use “fake” BTC?It comes down to technical requirements. The DeFi industry is now booming with billions of dollars flowing into lending, options, and other types of DeFi applications. The rate of its exponential increase is going faster and faster every day. However, this growth is primarily on the Ethereum blockchain. DeFi applications on Ethereum can only support ERC20 tokens, so BTC must be converted to the “fake” ERC20 version in order to be used for lending, borrowing, trading, etc. on all the latest and greatest hyped DeFi platforms out there. It is a legitimate use case. However, when wrapping BTC or other non-Ethereum assets to exist on the Ethereum blockchain, one must be especially careful about the mechanism used to wrap those assets.What Could Go Wrong?Now that we understand how wrapped BTC works and why people use it, let’s take a look at the potential dangers associated with this process. The fundamental danger with all wrapped BTC is the possibility that the “real” BTC on the Bitcoin blockchain could be unlocked and released to someone else, and leave token holders of the “fake” ERC20 BTC holding the bag. With the “real” BTC that that token was supposed to be used to redeem for now gone, the “fake” ERC20 BTC is now rendered worthless. The way in which this theft might happen wholly depends on the specific mechanism used for the cross-chain bridge that is used to bring BTC over to Ethereum or any other blockchain that has DeFi applications on it like Cosmos or Polkadot.Cross-chain Bridge TypesCentralized Custodial BridgeWith a custodial bridge, the address which BTC is sent to on Bitcoin is simply the address of an organization that promises that they will mint ERC20 BTC for you on Ethereum. In this solution, the person or organization managing the bridge must be trusted to hold the real BTC and not run away with it. The most prominent example of this model is the widely used ERC20 WBTC, which is solely and entirely backed by BitGo’s guarantee.Decentralized Smart Contract Managed BridgeOf course, in the world of blockchain and DeFi, many prefer decentralized, non-custodial solutions. Decentralized solutions are preferred and considered “safer” as they negate the need of a trusted third party (as is the case with BitGo in the WBTC model), and rather are directly managed by immutable smart contract logic.A few of the key technologies powering such solutions are secure multi-party computation (MPC) and the related technology of Threshold Signature Schemes (TSS).MPC is a cryptographic technique which allows for multiple participants to perform operations on a number of inputs without any participant revealing their own input to the group.TSS is a related cryptographic technique which allows for the MPC process to be completed as long as a certain threshold of participants join the process. For example, with 21 MPC participants and a TSS threshold of 15, as long as 15 or more of the participants join the process, the calculations will be performed successfully.Refer to this article from Wanchain’s Noah Maizels for a deeper dive into MPC and TSS with illustrative examples (specifically the varient of TSS known as Shamir’s Secret Sharing).MPC and TSS Applied to Cross-chain BridgesMany of the MPC / TSS implementations used by cross-chain projects / protocols are derived from the classic paper Robust Threshold DSS Signatures by Rosario Gennaro, Stanisław Jarecki, Hugo Krawczyk and Tal Rabin published in 1996.Unfortunately the principles described in this paper are often used directly by cross-chain projects without modification or innovation in their implementations of MPC / TSS.Wanchain introduced its implementation of MPC / TSS in its first cross-chain bridge between BTC and Wanchain all the way back in 2017. Our implementation of it drew heavily from the 1996 Gennaro paper, while also introducing an innovative algorithm which reduces the number of interactions in the MPC calculation process.An important concept in the application of MPC technology to cross-chain bridges is the relationship between the individual private key of each participating MPC node and the group private key of the whole node set.The group private key is the key which is used to control the MPC-managed locked account where the BTC is held on the native Bitcoin blockchain. Any holder of this key has full control over all assets in that account.However, no individual is ever meant to hold this key. Rather, a group of nodes work together to generate the group private key through the MPC mechanism described by Gennaro in 1996. This group private key is generated when each participating MPC node contributes their own individual private key. TSS is applied through this process to ensure that even if a few nodes are offline or deliberately choose not to participate, the process will complete as long as more than some threshold number of nodes participate. Therefore, the entire mechanism is highly fault-tolerant, and even if individual MPC nodes are malicious, it will not affect the protocol operation.Re-groupingWhile MPC allows for a group of nodes to operate a locked BTC account without any individual node holding the private key themselves, there still exists the possibility that the threshold number of MPC participants may collude to work together in order to steal the locked BTC. Node regrouping, or “churning,” is a common tactic used to reduce the possibility of node collusion. Regrouping is a technique where the nodes that comprise the MPC group that manages the locked account are periodically shuffled, so that no one same group of nodes manages the locked account for a long period of time. This shuffling makes it much more difficult for participants to identify and collude with each other.Of course, since the group private key is derived from a combination of all participating node’s individual private keys, every time a new group is formed, a new group private key and associated locked account are necessarily generated by protocol design.MPC & TSS in renBTC’s Cross-chain BridgeLet’s take a look at how the increasingly popular renBTC uses MPC and TSS in their cross-chain bridge. According to their technical white paper, their approach is also based on the aforementioned Robust Threshold DSS Signatures paper.On their website and official documentation, they emphasize that the management of cross-chain BTC accounts is done by a group of “dark nodes” using MPC and TSS (specifically, Shamir’s Secret Sharing), and the members of this group of “dark nodes” are periodically regrouped.Paradoxically, we found that the Bitcoin address provided by renBTC that users transfer their real BTC to for locking has not changed since the first day it went online.The process to generate renBTC is as follows. First, the user transfers BTC to a one-time address. See Figure 1 below.Figure 1Then, from that one-time address, the user sends their BTC to the locked account. See Figure 2 below.However, that locked account has never changed. As you can see in the figure below, it is a honey pot of nearly 9,000 BTC.Figure 2According to Gennaro logic, if the account address is really generated by MPC, and the dark nodes involved in account management really churn, then the account address must also be updated periodically. That’s how MPC works.Thus, there is a contradiction between the observed facts of the renBTC bridge implementation and the described technology in the documentation. This difference seems to indicate that the renBTC bridge does not in fact use the model as described in the technical white paper.We thereby doubt whether the locked BTC address was in fact generated using MPC. After a review of the code on GitHub and various technical documents, we were unable to find an explanation for this apparent contradiction.More Questions About the Cross-Chain ImplementationWe present these concerns about the implementation of renBTC because there are now nearly $100 million of BTC in what could potentially be a centralized storage locker. However, the problems with REN do not end there. The ECDSA threshold signature scheme adopted by renBTC does not set a secure enough threshold for their TSS scheme.Their TSS scheme is defined as so:n = 3t + 1n is the total number of participantst is the threshold number of nodes which may be malicious before compromising the security of the schemeFor example, if the t threshold is set at 15:n = 3(15) + 1n = 46In other words, under this scheme, only about a third of participants (15 out of 46) are needed to conspire in order to behave maliciously and steal the locked BTC under managment of the group.Such a low threshold is dangerous. The Byzantine Fault Tolerant (BFT) consensus mechanism has been similarly criticized within the industry as its security also fails with a third or more malicious participants.The TSS scheme of renBTC therefore poses some concerning security risks.Finally, we have one more concern to raise about the cross-chain process used to generate renBTC. According to the introduction of the REN technical white paper, during the establishment of its BTC account, “dark nodes” complete data interaction through a private chain, and the interaction data is encrypted, and its validity is determined by a zero knowledge proof guarantee. Therefore, whether the final individual private key is correct depends entirely on this zero-knowledge proof.So how to construct this zero-knowledge proof?The REN technical white paper does not give a specific implementation method, nor does it give relevant references, and there is no relevant code implementation on their GitHub. While their description is chock full of cryptographic terms, it is in fact lacking in the specific details which would allow one to judge the security of the mentioned zero knowledge proof:As I have stated above, our research team has cause for concern in regards to the execution of nearly all that is described above.A Few Final Thoughts…This year, especially in the last couple of months, the DeFi phenomena has grown into a massive movement. The types of applications and the total value locked in DeFi protocols has grown exponentially.Although some may cry “bubble”, the eye watering valuations are actually being driven by truly innovative products, and not just empty promises. However, as DeFi business applications flourish, core blockchain technologies, such as secure and decentralized cross-chain technology, have kept pace. The purpose of this article is not to single out REN in particular, but rather to ignite rational discussion about issues of security within the world of cross-chain DeFi.First, what level of compromise between the products described in a white paper and the actual implementation are acceptable?Second, for projects such as Ren that have not yet revealed their source code, what level of detail should we demand in their documentation? Are general references to engineering approaches acceptable, or should we demand specific implementation details?In the first ICO boom, we saw far too many projects which rose to incredibly high valuations based on a white paper and a slick story alone. The entire industry, including each of us individually, was more or less a victim.With that collective experience in hindsight, let’s make sure not to make the same mistakes twice. Let’s cut down on the technical mumbo jumbo, exaggeration, and hand waving, and focus on building practical solutions grounded in strong theoretical principles.Wanchain’s decentralized and trustless wanBTC is scheduled to launch on Ethereum in Q3 / Q4 of this year, and we welcome the community’s evaluation of it. We look forward to presenting more details about its implementation soon.“You can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time.” — Abraham LincolnAuthors:Li Ni, Dr. Guo ZhongzhongWith contributions from:Guo Wu, Noah Maizels, Nicholas KrapelsCited Works:[1] Rosario Gennaro and Steven Goldfeder. “Fast Multiparty Threshold ECDSA with Fast Trustless Setup”.

Coming Up on One Month of F...

Galaxy Consensus is Now Fully Decentralized and Community Operated!When Galaxy Consensus first launched over a year ago it was designed to serve as the security foundation for the Cross-chain DeFi ecosystem which we are currently deep in the process of #buidling. It was based on a modified version of Ouroboros Consensus which was first introduced by the excellent researchers at the prestigious IOHK organization who support the well known Cardano ($ADA) blockchain. Wanchain’s research team made a number of modifications to the original consensus protocol in order to improve both security and performance. Galaxy Consensus protocol is running smoothly today with over 28,000,000 WAN locked up in stake and delegations, 50 validator nodes, and over 2500 delegators.Total Decentralization, Here We Come!“Wanchain is now fully decentralized and controlled by the community.”When Galaxy Consensus was first launched, the Wanchain Foundation reserved a number of consensus slots in order to ensure that the protocol would run smoothly and securely during a short period after launching (any rewards from this were re-distributed to the community). Now that the protocol has been running smoothly for almost a year and has attracted a very healthy amount of stake to secure the blockchain, the foundation has decided it is time to remove the reserved consensus slots, shut down all foundation nodes, and turn over the entire network to the public, so that Wanchain is now fully decentralized and controlled by the community. Now that the core protocol is fully decentralized, the foundation has been laid for the decentralization of the Storeman Node controlled cross-chain bridges.Storeman Nodes, You Guys Are Up Next!“…which will allow for any asset integrated with Wanchain to flow freely back and forth from the Ethereum blockchain and back to their original chain”As we detailed in our 2020 Road Map: Mid-Year Update article, we are hard at work getting Wanchain 5.0 ready to go live. One of the most important parts of Wanchain 5.0 is the establishment of Storeman Node managed cross-chain bridges which will allow for any integrated with Wanchain to flow freely back and forth from the Ethereum blockchain and back to their original chain. While this has been made possible for BTC through a variety of different cross-chain bridges in the past, Wanchain 5.0 brings two important innovations to the table:Not only BTC, but also any asset which has been connected with Wanchain will be able to travel across the bridge (currently includes WAN, BTC, and EOS — soon to be expanded to include many prominent, high cap coins)In contrast to many other current cross-chain asset solutions (WBTC, pBTC, and others), Wanchain 5.0’s bridges will be powered by a totally decentralized, permissionless, and trustless group of Storeman Nodes.The Open Storeman Initiative“…the first fully decentralized and permissionless cross-chain mechanism which supports transfer of value between any two smart contract enabled blockchains.”In order to shift from the current permissioned cross-chain bridge model to the decentralized and permissionless one, the Wanchain Foundation has begun the “Open Storeman Initiative” (which is mentioned in our recent roadmap update). This initiative is powered by a new economic incentive mechanism which has been developed by the expert minds at Wanchain’s research and development team. It is being developed by the same group of individuals who developed Galaxy Consensus, which is running smoothly and securely today. Under this initiative we have begun trialing the new decentralized model with a select group of trusted validators from the community. These validators are helping to test this new model, and work out all the kinks in the crypto-economic incentives system which ensures the security of the cross-chain bridges. (If you are a Wanchain validator interested in participating in the initiative, feel free to reach out to me at noah@wanchain.org). Once this initiative is widely put into effect with the launch of Wanchain 5.0, it will become the first fully decentralized and permissionless cross-chain mechanism which supports transfer of value between any two smart contract enabled blockchains.Powering the World of Cross-Chain DeFi“…enabling a world of true cross-chain DeFi, rather than the semi-centralized version we have today”As we have seen with the recent explosion of value within the DeFi ecosystem, cross-chain economic bandwidth (that is, the amount of cross-chain value which can be brought over to DeFi applications on other chains), is becoming a serious bottleneck limiting the growth of the ecosystem. The demand for truly decentralized cross-chain exchange of value will only continue to grow, and is not set to slow down any time soon. With only about 0.1% of BTC transferred to Ethereum, and very little if any value from other chains participating in the DeFi ecosystem, the room for growth is enormous. Wanchain is aiming to play a major role in solving the issue of economic bandwidth, and enabling a world of true cross-chain DeFi, rather than the semi-centralized version we have today.The question now is, who will be with us on this journey together, and who will get left behind…?About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain and Pundi X Join F...

Use WAN coin and Wanchain wrapped assets WBTC, WETH, and WEOS to pay for your favorite goods and services!Wanchain and Pundi X first partnered in May 2018 to extend cryptocurrency accessibility to the public through the native Pundi X point-of-sale devices (XPOS). In October 2019, Pundi X started its own Wanchain validator to take advantage of Wanchain’s Galaxy Proof of Stake system, which takes inspiration from Cardano’s Ouroboros but adds several layers of improvements including increased random selection, speed, and security.We are now pleased to bring you the most important update to this partnership, Wanchain’s native WAN coin and a clutch of wrapped cross-chain assets on the Wanchain blockchain will be integrated into all of the Pundi X — XPOS devices. WAN coin as well as the WBTC, WEOS and WETH wrapped assets on the Wanchain blockchain will be accepted cryptocurrencies in XPOS systems. This integration will make Wanchain’s cross-chain digital assets accessible and usable to over 700,000 existing XWallet users.XPOS is a blockchain-based point of sale mobile terminal that allows different tokens and coins to be used to pay for different goods and services. Pundi X will also be facilitating a number of XPOS devices for use within Wanchain’s enterprise and public blockchain partner ecosystem. A fiat gateway for merchants wishing to convert Wanchain’s native WAN coin and other Wanchain cross-chain digital assets into government-backed fiat currencies via the Pundi X distributors network is another benefit to the enhanced partnership.The integration of Wanchain’s cross-chain functionality is especially useful for both shoppers and merchants who would like to leverage assets and utilities from multiple blockchains while out shopping. With only their smartphone and Wanchain’s interoperable technology, shoppers will be able to easily utilize assets and applications from multiple different blockchains while out and about. Merchants, on the other hand, can accept a wide range of assets from different blockchains without needing to worry about whether they have the right software for each different blockchain.Aside from the XPOS and X Wallet integrations, Pundi X and Wanchain will also release an adoption-ready crypto gifting system and enhanced social media tipping bot that users can take advantage of when sending to other users. Initially, the integration will allow Telegram users to send their favorite assets to each other. You can take a peek at this video to see how this will look like upon completion of the Wanchain ecosystem integration.Wanchain and Pundi X will continue to operate together to bring cryptocurrency adoption to the masses, with new campaigns in the works for 2020. Both projects will also seek new opportunities in the African and South American regions, where cryptocurrency demand is in higher demand than other regions of the world, mainly due to political unrest, galloping inflation and overall uncertainty about the future of their government-backed currencies.Given the COVID-19 global pandemic, we are confident that the blockchain industry, particularly the cryptocurrency markets, will see a rise in usage in the coming years. As more and more governments reduce their national interest rates, increase quantitative easing and enterprises cut back on employment, the next technological shift to the blockchain will be inevitable. We are establishing the base-layer foundation in preparation for the next wave of crypto users. With the tools provided by Wanchain and Pundi X together, merchants, users, and partners can more easily #buidl with the new internet of value.An interconnected digital economyFor the first time in history, decentralized proxy-token forms of Bitcoin, Ethereum and EOS can be traded seamlessly across different networks. The integration will bring these cross-chain digital Wanchain assets to both the Pundi X user and merchant networks. Interoperability standards are still a few years away from being properly adopted but with so few decentralized interoperability solutions out there, we are certain that the time for Wanchain’s interoperability usage is here. Along with its development of many cross-chain assets to come, a critical mass of value, adoption and flexibility will lead to a new era of cross-chain finance.Spending cryptocurrencies seamlessly is not a new thing, but spending cryptocurrency through blockchain XPOS devices is. We take the best of both worlds and facilitate the ease-of-use and decentralization of these cross-chain assets to hundreds of thousands of users and thousands of merchants thanks to Pundi X’s already established network of merchants. While many forms of cryptocurrency use cases have been seen, the sheer scale and disruptive nature of the crypto commerce movement has yet to take hold.With millions of dollars being transacted through the merchant system every quarter, we are excited to embark upon this journey at the dawn of cross-chain crypto commerce. Wanchain will provide all of the necessary resources to bring more use cases to our ecosystem and those chains that connect to us through Wanchain’s unique interoperable bridge technology.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

June 2020 AMA

All your burning questions answer by the Wanchain core team!AMA answers from Wanchain team members:Jack Lu — Founder and CEOLini — VP of OperationsWeijia Zhang — VP of EngineeringDemmon Zhong — Director of Research and DevelopmentNoah Maizels — Director of CommunicationNicholas Krapels (Prof. K) — Director of Growth and StrategyJune 2020 AMA questions and answers1. I was checking on wanchain github repos and saw the T-bridge contracts. I remember it was released as wanchain 4.0 which was supposed to be major release. However I saw no continuation of development since the first releasr in January, and zero stars/forks. I wonder if anyone is using it?Also are there follow ups on the crosschain exchanges? The products are there but I dont see much effort, if any, from the operators to attract users..@Jack Lu @Weijia ZhangT-Bridge is an enterprise solution that connects private blockchain with public blockchains. There are some enterprises that are interested in Wanchain’s Lanchain technology and are in exploration of T-Bridge cross-chain solutions. The T-Bridge solution will most likely adopted as enterprise solutions and its activities will most likely not shown in public Github. — WeijiaT-Bridge will play a major role in our domestic China BD work. It will be essential for connecting private Lanchains together with each other when the need comes up for interoperation between private chains. — Noah2. RationalChimp: Could you talk more about the interoperability standard and also about your relation with the EEA cross-chain task force with ConsenSys?Answer: Enterprise Ethereum Alliance (EEA) formed the Cross-Chain Interoperability Task Force (CITF) to explore the possibility of establishing standards and specifications for cross-chain interoperability. CITF has worked with various EEA team members and focused on the following areas: 1) Collecting use cases for cross-chain interoperability and publishing use case document to describe the architecture and scope of problems the task force intend to solve. The board of directors of EEA has approved the release of use case document for cross-chain interoperability; 2) collecting cross-chain interoperability solutions within EEA community and summarizing solutions that are common; 3) working on the common problems and core components for cross-chain interoperability and coming up with specification that member companies can use. The task force has a technical roadmap approved and we are working to deliver that items specified in the roadmap. ConsenSys and Wanchain are both active member companies of EEA and we have shared common visions in cross-chain interoperability standards and specifications. Cross-Chain Interoperability Task Force are currently co-chaired by members from Wanchain and ConsenSys. — Weijia3. Cihan Oz | Wonder Wasp: Hi, any other ico, ieo planned in the near future?Answer: Wanchain finished its ICO long ago and the project has been running operationally for a long time, so no such ICO or IEO plan. However, there’re several ecosystem projects which have been built on Wanchain’s mainnet and they had/will have their token sale plan as ICO, IEO, or IDO (Initial Defi Offering). The projects like RiveX, FinNexus, Bitlydex and a couple of projects under development. — LiniSome of the projects mentioned by Lini may even go on to offer additional token offerings besides the project’s own token. For example, FinNexus will likely offer a variety of other tokenized assets in the near future in addition to the tokenized P2P lending product UM1S which was a part of the FinNexus token issuance event. — Noah4. Vad Bill: When will be the 1st STO?Answer: As Wanchain is collaborating with STO platform Tallium right now so we have discussions partners such the 1st STO. However, we are following very strict principals to choose the best quality projects to have security tokens on our platform and the process may take a bit longer time. — Lini5. USDT-Empire: Mr. Oliver, any idea about the requirement to be a storeman? I mean how many wan coin do you need to be a storeman? we’ve asked this question before and we got an answer that the team didnt decide yet.. what about now.. is it still unknownAnswer: We tentatively set 50k Wan as the requirement to set up a Storeman Node in order to accept delegation. For each bridge, the top number of nodes with highest amount of staking (self-staking + delegation) will be selected for each round. — Jack6. Valentin Hus: In the May AMA you have stated you are focusing in developing Lanchains. How are those Lanchains bringing value to the Wanchain ecosystem? How are the services of Wanchain being paid to the Wanchain Foundation LTD by the customers of Lanchain services? What are those funds from Lanchain services being used for? I guess Wanchain Foundation is signing contracts for maintenance of those Wanchains, so that would mean receiving recurring revenues for the Foundation…Are you planning to release yearly or quarterly financial reports about Wanchain Foundation LTD financial situation? The community will be pleased to see some financial transparency from Wanchain Foundation LTD after receiving over $25M during the ICO…Answer: Lanchain / enterprise efforts are definitely more focused on the China side right now. There’s just so much demand for it there, there have even been direct mentions of it as a priority from Xi Jinping, so we get a much better return by focusing there. That’s actually going to be the main focus for Steven He, our new Vice President of Business Development, and he will be leading a team focused on this. Of course he will also push for public chain solutions when possible, but most demand from big industry and gov in China is for private chain solutions. It might not immediately lead to more public chain usage, but when there begins to be a need for all these private chains to interoperate, it will. I think more importantly though it will increase the prominence of Wanchain in the country and around the world, and funds raised from private chain solutions will go back into the foundation to help fund further public chain development. — Noah7. BESH: Any blockchain integration this quarter as it says on roadmap ?Answer: We made some adjustments as stated in our mid-year roadmap update. We are doing a major upgrade on the cross-chain bridge implementation on Open Storeman, Two-way Bridge, Fast Cross-chain Transaction and etc. We plan to integration more chains after 5.0 release. — Jack8. Red Zebra: at the moment, it seems that the focus is clearly still on development. but the products that are already out are not being used widely. what will Wanchain do to increase adoption/usage? mr. jack lu, is the objective still the same: Wanchain Top 10? thank youAnswer: We have a number of initiatives in the near future set to address this, top of them are the Dual DApps program and the Global Partner program. For Dual DApps we will release and promote dual versions of DeFi DApps on both Ethereum and Wanchain. The pilot DApp to be launched under this Wanchain ecosystem initiative is the FinNexus FNX Options platform, which currently operates on Wanchain but will soon operate on both Wanchain and Ethereum from the same webpage / wallet interface. This first Dual DApp will be followed by others. We will promote the use of our cross-chain assets within these applications on Ethereum, while also promoting the use of the Wanchain versions of each Dual DApp to users who would like to take advantage of Wanchain’s far cheaper gas fees and much faster transactions. The global partner program is a program where we incentivize our global partners to promote Wanchain’s applications and technology. Specifics about how to join and the incentives structure will be released soon. — Noah9. adam eve: Question for Jack Lu.Apart from all the great things wanchain is doing, the area for Marketing, Communication and Community-building stays far behind and is not on a professional level. I see the struggle, there mostly seems to be no strategy, no feeling, no experience and no enduring energy in this area. How will you professionalize this area to bring it in line with the other high level parts of your company?Answer: As for marketing, we’re not going to be repeating the same strategy we used in the past. We have found major media blasts cost a lot of money and are not that effective. Of course press releases and publishing to prominent media outlets will still play some role, but we will be focusing more on some other new strategies. Some of them which I have mentioned above include the Dual DApps initiative and the global partner program.Another strategy which will be a big focus for us going forward is partnership based marketing. The idea behind this is that we pursue partnerships based on integrations with other crypto projects that already have solid user bases, such as multi-coin wallets, for example. We can then tap into that project’s entire userbase by promoting WAN and WAN staking directly to the users.Other strategies include things which are developer focused, and may not be that apparent to the general user. For example, we will be totally redesigning our WanDevs and ExploreWanchain websites to be more useful for developers, and we will be releasing new software tools which make it easier for devs to add Wanchain’s cross chain tech to their projects. While these perhaps are not th most visible of things to the average user, they are very very important for attracting and retaining developer interest. — Noah10. Napster | Wonder Wasp: Hello. Are there any plan to pull more developers to the chain development, like expanding the development team?Also, any hackathon is being planned in the near future to develop something on the chain, for example dApp?Answer: We are currently in discussions with a partner about organizing a hackathon related to cross-chain applications, but we do not have specific plans for organizing a hackathon in the near future. Organizing hackathons using our cross-chain tech will likely become a bigger priority for us after the launch of 2-way bridges and associated developer tools with Wanchain 5.0.— Noah11. Groovi80 Lassen: Is there a sales team in place for WAN? from my research I just find a lot of smart people, however a marketing and sales team can do wonders, I know this as this my area of profession in traditional techAnswer: We have just been joined by Steven He, our new director of BD. Steven comes from more the traditional tech industry with 25 years experience in business development and sales, and also is VERY well connected in China with some very important people (which is especially helpful for doing business here). This is more related to Lanchain as it is our major commercial product. When it comes to integration and expansion amongst the DeFi ecosystem it is less a process of SALES and more a process of exploring mutually beneficial integrations with other projects. On this front we will be doing major outreach to various Ethereum DeFi projects to get our cross-chain tokens integrated. Moreover we will soon be launching our new global partner program in which we will leverage our community to promote Wanchain. Look forward to more information on this initiative soon. — Noah12. Panzer Wagen (question from July, but answer would be great): Aren’t you worried that REN did launch BTC-ETH bridges on tech from your WP and is now taking wan spot, meanwhile wanchain will have 2 way bridges close to Year end. And wan is completely loosing spot in top of crosschain projects?Answer: In contrast to REN, wanBTC will use a truly decentralized mechanism for the bridge. REN has decentralization on their roadmap, but so far that’s not what’s happening. That’s because true decentralization is hard. Also, Storeman Nodes can be built to cross wanTokens into more blockchains than just Ethereum. That’s not in the REN tech roadmap, as far as we’ve been able to ascertain.The main improvement renBTC offers over WBTC is simply that it does not require KYC/AML to do the wrapping. To be honest, that’s a little weird because what they’re currently doing is still very much a centralized solution. A big reason why renBTC has soared recently is UXUI based. REN has built a page that automates the conversion of renBTC into WBTC, which is currently much more useful because it is accepted as collateral on Compound and Maker. REN has also done some liquidity mining programs with Curve and Synthetix to increase their profile.What we’d like the community to keep in mind, though, is that we are still so very early in the wrapped BTC industry. The total number of BTC tokenized on Ethereum right now is <0.1% of total BTC supply. There is practically no hypothecation of BTC onto other blockchains. The number of wrapped BTC across all chains could easily 100x from here and we’d still only be at <10% of BTC supply.We believe that the wanToken technology will prove itself to be the best alternative out there in a highly competitive but exponentially growing niche in the crypto industry.— Prof. KAccount: @Nicholas Krapels @Noah MaizelsOPTIONAL, TAKEN FROM THE CHAT FOR JUNE12. Could you update us about lian lian pay? @Ni Li13. Will Wanchain join ERC1400 alliance? https://thesecuritytokenstandard.org/ @Jack Lu @Weijia Zhang14. Where can I find a run down of wan tokenomics? Especially in regards to running a node? Is WAN a competitor to REN? No details of how the tokenomics will work with Storeman? Does “Open Storeman initiative Phase 1” mean the system is ready to start minting like REN? @Weijia Zhang @Zhongzhong GuoAnswer: Compared to REN, WAN has a bigger vision. With Open Storeman and two-way bridge, different digital assets flow through different blockchains with true decentralization and low friction.We have designed a robust incentive mechanism for Open Storeman. Under this mechanism, storeman nodes’ work and contributions are accurately evaluated. Honest behavior is rewarded, while malicious behavior will be slashed. So every storeman node is ensured to follow the protocol strictly. Besides, we also designed dynamic rate of return to achieve balance between Open Storeman and Galaxy consensus. — Demmon15. Is wanchain involved with some work with Chainlink? @Jack Lu @Noah MaizelsWe have an ongoing partnership with them and they are available to be used for Wanchain based applications. They will most likely be a part of future Wanchain projects in addition to Band.16. can you please tell us more about 2-way bridges and lanchain integrations (if you are working on something interesting ) regarding also BSN news Jack? @Jack Lu @Ni Li17. Crosschain crypto commerce partnership…. This should be announced in this month?It should be announced this week — Noah18.

2020 Road Map: Mid-Year Update

Building a Cross-Chain DeFi ecosystemThe last six months have been a whirlwind of furious research and development for the Wanchain team. It may be the understatement of the century to say that a lot has happened since January 2020 and, as a result, our vision has become sharper and more focused. Today we update our community with a new development calendar and roadmap that reflects this shift in strategic direction. We’re more excited than ever about what lays ahead of us, but to understand where we are going, you need to have some idea about where we’re coming from…The Genesis of Cross-Chain DeFiThe Wanchain dev team has had their noses to the grindstone for the last 6 months, laying the foundations for a world of truly decentralized Cross-Chain DeFi. While DeFi has been a buzz word for quite while, the DeFi ecosystem is still in a relatively early stage of development. As young as DeFi is as a movement in the blockchain industry, Cross-Chain DeFi is in an even more nascent stage.Cross-Chain DeFi’s Early Building BlocksOne of the earliest cross-chain concepts was that of the atomic swap between two different blockchains. While this innovation allowed for the creation of simple cross-chain use cases, it was limited in its utility and did not allow for the creation of complex financial applications.The launch of bitBTC on the Bitshares exchange was one of the first attempts to represent a native blockchain asset (BTC) on another blockchain as a placeholder token for use in a financial application. The bitBTC token was meant to establish a price peg between bitBTC on the Bitshares blockchain and BTC on the Bitcoin blockchain. This concept had the potential to unlock a whole world of new use cases since it allowed for the representation of multiple different tokens representing assets from many different blockchains. Real world assets such as USD or CNY could even be represented using this mechanism. These price-pegged tokens interacted directly with each other through smart contracts simultaneously on a single blockchain. Due to serious problems in the design of bitBTC and other similar Bitshares-based assets, bitBTC was unable to keep its peg price. Unfortunately, bitUSD and bitCNY suffered the same fate and the initial promise of cross-chain decentralized assets never really took off.Cross-Chain DeFi Evolved with 1:1 Exchangeable AssetsThe real beginning of cross-chain DeFi was around late 2018 / early 2019 with the introduction of the original ERC20 WBTC on Ethereum. WBTC stands for “wrapped BTC” and, similar to “wrapped ETH” or WETH, the “wrapped” part refers to a simple smart contract that wraps around the core digital asset so that the crypto asset can function in the world of interlinked smart contracts that is the DeFi world of today.While Wanchain does maintain its own version of “wrapped” BTC as a WRC20 token, the ERC20 version of WBTC has taken off, largely due to its ability to guarantee a 1 to 1 swap with actual BTC held on the Bitcoin blockchain. This conversion mechanism, combined with increasing depth of these fungible assets, has largely eliminated the price pegging issue that doomed bitBTC. The relatively recent integration of Ethereum WBTC into pioneering DeFi applications such as MakerDAO, Compound, and others — marked the beginnings of the widespread use of cross-chain value in DeFi applications. Today, there are 11,505 WBTC on the Ethereum blockchain, representing more than $105 million of value wrapped into Ethereum smart contracts. In total, according to BTConEthereum.com, more than $140 million of value denominated in bitcoin rides on the Ethereum blockchain.With a total BTC market cap of more than $168 billion and few use cases that utilize that value besides HODL, that number is set to explode upward in the near future. Right now we have less than 0.1% of the value of BTC on Ethereum. That’s how early we are.One of the biggest criticisms of WBTC is that in order to make the 1 to 1 exchange of BTC to WBTC or vice versa, one must pass through a centralized service provider. Obviously, this mechanism is completely contrary to the decentralized and permissionless ideals of cryptocurrency in general. As a result, a number of alternatives to WBTC on Ethereum have emerged, most notably renBTC and pBTC. However, their current combined value pales in comparison to WBTC. Due to bandwith or mechanism design or simply just community awareness, a clear winner has yet to emerge.It is not unreasonable to expect a 100-fold increase in the number of bitcoins wrapped on Ethereum. That number does not include any potential increase in the value of BTC itself. We are still just so early in this cross-chain movement of value. It’s a problem that Wanchain engineers have puzzled over for years. We now think we have an elegant solution that we can share with the world!Wanchain’s Cross-Chain SolutionYears ago, Wanchain pioneered an alternative model for generating cross-chain tokens that makes use of secure multiparty computation and threshold secret sharing (TSS) to allow for a group of nodes called Storeman Nodes to perform the cross-chain exchange of BTC to WBTC on Wanchain. Simply put, this novel design allows for the exchange between BTC and wrapped BTC to happen without any centralized party managing the transaction. The cross-chain exchange is permissionless, trustless, and decentralized — which has clear advantages over other centralized solutions. We already have this working on Wanchain.Today, we’re happy to announce that we intend to introduce this design to the Ethereum blockchain. We are happy to introduce you to wanBTC, an Ethereum-based wrapped bitcoin solution, that we will be rolling out soon.Wanchain 5.0 Will Enable True Cross-Chain DeFiUntil recently, Wanchain cross-chain implementations have focused on building Storeman Node based bridges to bring assets from other blockchains to Wanchain. Now that we have perfected our cross-chain technology, we aim to extend it to not only bring cross-chain tokens to Wanchain, but also to other blockchains, primarily Ethereum for the near future. But this could be applied to any blockchain that we support, which for now is BTC, ETH and EOS but we will be integrating more chains shortly.Two-Way BridgesWanchain 5.0 introduces the concept of “two-way bridges.” Two-way bridges use the same Storeman Node technology used to bring cross-chain WRC20 assets to Wanchain to bring cross-chain ERC20 versions of assets such as BTC, EOS, and WAN to Ethereum. In the near future, new blockchain integrations will enable more cross-chain tokens from other chains to be brought to Ethereum.We will first focus on integrating additional Ethereum and Bitcoin forks. ETC and LTC combined, for example, represent about $3.5 billion of economic bandwidth that currently cannot participate in the DeFi protocols that have recently brought the cryptocurrency market back to life.Cross-Chain LiquidityBuilding two-way bridges to bring Wanchain’s cross-chain assets to Ethereum is one important part of our plan, but perhaps equally important is actually moving enough of those assets over to Ethereum to ensure that there is sufficient liquidity for each asset to make them useful. Our first priority will be to ship over large quantities of cross-chain ERC20 WAN for usage as collateral in our Storeman Nodes which will form the bridges connecting Ethereum. We will also work to promote the integration of this new ERC20 WAN token, wanWAN if you will, into a variety of Ethereum DEXes, AMMs and other DeFi products.Note: This new cross-chain ERC20 WAN token that will serve as a placeholder for the native WAN coin that lives on the Wanchain blockchain will be a new and separate smart contract with a new address that is completely different than the old ERC20 WAN fundraising token issued during the original Wanchain ICO. That original ICO version of ERC20 WAN is no longer a valid token for any purpose.Our second priority will be to bring over a large supply of cross-chain ERC20 wanBTC and use it to enhance liquidity on a variety of Ethereum DeFi applications. As we intimated earlier, we believe that the limiting factor of DeFi on Ethereum will soon be the lack of available economic bandwidth. We expect DeFi user growth to outpace the growth in value available in native Ethereum assets. Therefore, we think a truly decentralized method for importing valuable assets from other chains for use as Ethereum tokens will provide tremendous value to WAN token holders and the DeFi movement in general.Our initial focus will be on providing wanBTC to wrapped BTC pools which aggregate a variety of different ERC20 BTC versions into a single pool. Later, we will expand our focus to promote the use of our cross-chain wanBTC in a variety of different DeFi applications including DEXes, lending applications, derivatives, and liquidity pools such as Uniswap and Curve. The fantastic part about this strategy is that we can also facilitate the transfer of these bridged assets to other chains should DeFi prove to be constrained by the increasing costs of Ethereum gas usage.The next step would be to enable the trustless transfer of assets from other blockchains such as EOS and other future integrations as cross-chain assets on Ethereum. Think wanEOS, wanLTC, wanETC, and so on — a family of wanTokens ripe to significantly enhance the economic bandwidth for DeFi applications. After bringing a sufficient supply of cross-chain tokens, we will promote their integration into a variety of DeFi applications in addition to our cross-chain WAN and wanBTC .Dual DApps InitiativeAs a part of this strategy, we will release and promote dual versions of DeFi DApps on both Ethereum and Wanchain. The pilot DApp to be launched under this Wanchain ecosystem initiative is the FinNexus FNX Options platform, which currently operates on Wanchain but will soon operate on both Wanchain and Ethereum from the same webpage. This first Dual DApp will be followed by others. We will promote the use of our cross-chain assets within these applications on Ethereum, while also promoting the use of the Wanchain versions of each Dual DApp to users who would like to take advantage of Wanchain’s far cheaper gas fees and much faster transactions.That, in a nutshell, is our strategic response to the DeFi boom. Wanchain was founded on the principle of providing the infrastructure that connects the decentralized financial world. It’s even written on our website. We believe this pivot is, in fact, more aligned with our original vision than what we’ve been doing recently. We’re incredibly excited to set out in this new bold direction and play our part in the explosion cross-chain DeFi to come.And now, without further ado, we present our updated mid-year roadmap.Presenting the Updated 2020 Roadmap:Roadmap Updates Reflect Changing PrioritiesAs a close observer you may have noticed several important changes to the 2020 roadmap, which we outline below.Important AdditionsAll of the newly added roadmap items support the new Cross-Chain DeFi vision laid out above. They fall into several categories:Cross-chain infrastructure enhancementsPromoting the use of WANEnhanced decentralizationEcosystem buildingWanchain 5.0, for example, falls into a number of these categories. The most important part of Wanchain 5.0 is the enhancement of Wanchain’s cross-chain infrastructure to bring cross-chain assets to Ethereum. Another important aspect of Wanchain 5.0 is the implementation of Open Storeman nodes. This initiative opens up Storeman Node membership to any node operator who would like to participate. Anyone can run an Open Storeman node without permission, and all node operators are kept in check by on-chain economic incentives and punishments. This change should greatly increase the capacity for decentralization of the Storeman Node system, and makes it truly permissionless and trustless. Wanchain 5.0 will also include an upgrade to the cross-chain process in order to allow for faster cross-chain transactions.Promotion of the WAN token in both its native coin and ERC20 token forms is one of the key priorities of the roadmap updates. The establishment of more and more Storeman Nodes used to power 2-way bridges will require a large amount of additional staked WAN to serve as collateral. Multi-asset collateral will be implemented so that other assets besides WAN can be used, but WAN itself will be heavily promoted for use as collateral. This new feature of our token economy will in turn offer new opportunities for Wanchain community members to delegate their WAN to Storeman Nodes in order to contribute to securing the cross-chain bridges.The release of reserved Galaxy Consensus mechanism slots to the public is a massive step bringing Wanchain closer to 100% decentralization.The newly launched DApp Store is a key element in our ecosystem building plan. The DApp store makes it easy for developers to let Wanchain users access their applications and perform cross-chain transactions within the same interface.Our support in the launch of DApps built by Wanchain ecosystem projects is an important element of our above mentioned strategies as these DApps will form the basis of the Dual DApps to be launched on Ethereum after the implementation of 2-way bridges.Other Important ChangesNew cross-chain blockchain and token integrations with Wanchain have been postponed until after the implementation of Wanchain 5.0. The purpose of this change is allow for the faster development of two-way bridges to bring our current menu of cross-chain tokens to Ethereum. The postponed blockchain and token integrations will take place after the two bridges are established, and will be used to bring a wide variety of different cross-chain assets to Ethereum.Proofs of concept and new standards have been labeled as “decreased priority” in order to let us focus more on Wanchain 5.0, the development of 2-way bridges, bringing more cross-chain assets to Ethereum, and development and promotion of more Dual DApps.Sharply Focused on the Way ForwardThe second half of 2020 will be a very exciting time for the Wanchain community! It will see the launch of new cross-chain assets on Ethereum, dramatically increased decentralization of low level infrastructure, and an expansion of our DApp ecosystem. In addition to the core roadmap items we have outlined above, don’t be surprised if you also see a variety of important enhancements to both general user and developer facing applications. You may see enhancements to our mobile, desktop, and web wallets, as well as developer facing tools which make adding cross-chain functionality to DApps and wallets as easy as including just a few extra lines of code. You may also see improvements to a variety of Wanchain ecosystem websites and tools such as blockchain explorers, documentation websites, and possible homepage enhancements as well.But let’s revisit the most important announcement in this mid-year update:Say hello to wanBTC!Here’s looking forward to another six months of buidling!About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Mobile Wallet 3.0: DApp Sto...

The 3.0 update introduces the mobile DApp store to showcase Wanchain’s rapidly growing DApp ecosystem — Including the all new “Red Packet” DAppDownload the new wallet now (scroll down to “Mobile” section — currently supports Android mobile phones)DApps, DApps, Dapps!The recent months have seen the rapid growth of Wanchain’s ecosystem of DApps from projects such as FinNexus, RiveX, and the Wanchain dev team itself. Up until now, the interfaces for these DApps have been available through the desktop wallet and web versions only. That all changes with the newest WanWallet mobile wallet release — now you can use all those Wanchain DApps on the go!In addition to general UI and language improvements, the 3.0 release treats WanWallet users to the newly added Wanchain DApp store which features all the same DApps currently available in the desktop wallet plus one all new mobile exclusive DApp to reward mobile users for their wait!Currently available WanWallet DApps:Wandora Box — Crypto price prediction game from FinNexusJack’s Pot — No loss lottery from FinNexusWRDEX — Decentralized cross-chain exchange from RiveXBitllywood Dex — Decentralized cross-chain exchange from BitllywoodALL NEW!!! — Red Packet (currently mobile exclusive)DApp Store DApps“Red Packets” — A Fun and Social New Way to Send CryptoSending crypto is more fun with Red Packets!The name “Red Packet” comes from the Chinese traditions of giving money in red envelopes at festivals and special occasions. Popular Chinese mobile payment applications such as the popular Alipay, Wechat Pay, and many others have adapted this into a modern mobile application feature which allows users to send cash inside “Red Packets” to individuals or groups. WanWallet now brings this feature into the world of blockchain.Red Packets have a number of cool features which make them different from a direct transfer of assets. Wanchain’s crypto version of the Red Packet includes the following features:You don’t need the address of the recipient:Simply generate and send the Red Packet code to someone in a private message, and they will then be able to use the code to redeem the assets directly to their wallet. There is no need for them to share their address in advance.You can generate a single Red Packet code which can be redeemed by multiple people:This can create opportunities for fun interactions and social engagement by generating a Red Packet code which can be redeemed a number of times specified by you to a group chat where people can compete to see who can redeem the Red Packet codefirst.When generating a Red Packet code with multiple redeems, you can choose either the same amount of tokens for each redeem, or a random amount:This allows for fun games in groups where you can play to see who wins the most, or use it for decision making (to decide who goes first in a game, or who gets to pick up the dinner bill, etc.)A Red Packet code will eventually expire and the assets will return to the wallet of the person who generated it if it is not redeemed after a time limit:This ensures that assets you send will not be lost in case you send it to an inaccessible or inactive account. It also allows for the interesting social use case where you can send a Red Packet code to a friend as an offer (for example, to pay for dinner), and your friend has the opportunity to redeem and accept it, or wait for it time out and return to you.You can also generate a Referral Red Packet code which rewards users for sharing the codeBy incentivizing the sharing of your code, you can make your Red Packet spread virally!Try out the Red Packet DApp and see if you can come up with any other fun and interesting Red Packet use cases!

Wanchain and Talium — AMA R...

Wanchain and Talium — AMA RecapThis is a full (nearly) recap of an AMA (Ask Me Anything) session that happened on Wanchain Telegram chat on Tuesday 23.06.2020.Oliver Birch: Hey all!Thank you for joining today’s AMA.Please welcome Julien Brodier @ethjb — CTO of Talium and François de Chezelles — CEO of Talium. And CEO of Wanchain Jack Lu @jackxlu.Let’s start with some brief introductions from Talium.Francois and @ethjb , if you can provide a brief introduction, including your background, what you did before getting into blockchain and what you are currently up to with Talium.François de Chezelles: Hi all, thanks for having us. I’m François de Chezelles, co-funder of TALIUM. Background: studied aeronautics & astronautics at MIT, then moved 18 years ago to IT engineering where I held management positions. I co-created TALIUM in 2012, an engineering IT servicing team specializing in complex systems integration.As an Oracle partner, we’re used to working in corporate international environments. In 2015, we started focusing on blockchain and applied cryptography. Tokenization proved the real deal, hence the platform we shall discuss.Julien BRODIER: Hi everyone, I’m the also the co-founder of Talium and the CTO. Started in 2004 with ‘standard’ software engineering for companies and CTO of companies since 2006. I’m leading the developement team on our Digital Securities management platform.Oliver Birch: Thank you Francois and Julien, we will now open questions up to the community.Question 1.Hello everyone thank you for this AMA, from my understanding, Talium will safely keep all investor documentation, while Wanchain provides the platform that will likely issue tokens in the wrc1400 standard. Can you provide more details about this partnership? which part will be in charge of bringing investors ? and will be responsable of compliance with current regulations ?Julien: Great question @Mussino . The platform provides a great infrastructure to ensure compliance rules are enforced. Issuers will be able to setup simple or complex compliance rules using a rule engine. The platform securely stores due diligence documents and KYC documents in a safe vault. Talium is not responsible to execute to due dil itself, it is done by a compliance officer for the issuerCommpliance is one of the key differenciators of our platform. We provide ‘KYT’ (know your transactions) which is more granular than KYC.Oliver: Specifically, partnerships — Wanchain is in talks with a few potential partners to launch the first STOs by the end of this year. Some partners in Canada (as of now). We will have more news about that once we finish the full integration and have security token exchanges lined up.Question 2.Do you have a partner audit firm in your STO initiatives at Talium that would also be involved in your business with Wanchain?Julien: Yes, we work lawyer firms to ensure our platform’s processes are compliant and also to give advice to company wanting to issue tokens.We are about to release an audit publicly also.Question 3.How do you plan to gain adoption fast enough that the market will not be saturated with other similar project by the time you launch or what advantage could you offer?Julien: Great question. We think we have a competitive advantage with our compliance modules, which is quite unique. We think most platform could have a hard time staying compliant with only smart contracts to model compliance rules. We have mainly a tech provider position, which mean we are not affected. We mainly provide the platform for financial firms who have necessary agreementsQuestion 4.Bonjour François, ça va? interesting background. How come you made a move from aeronautics and astronautics to blockchain?@ethjb and François, have any of your corporate partners shown interest in developing more solutions using blockchain technology or raising money through this new STO mechanism ?François: aero/astro is awesome yet tackles one area. IT engineering tackles all. I got involved in state-of-the-art IT projects and R&D, then blockchain popped up, along with applied cryptography. Totally loved it as it enables huge added value (when relevant of course).Question 5.Hey @ethjb what has been the biggest challenge when launching the STO platform? Has it been a lengthy process to get everything compliant in France?Julien: Good question also. Many big challenges, but on top, i would say : the ability to build a multi-jurisdictional and multi-assets platform and stay compliant. One exemple : issuing equity tokens is not hard. What is hard is to ensure any transaction keeps compliant even on the secondary market. You have to satisfy regulatory constraints, company constraints, shareholder constraints, and those rules can change.François: Another challenge has been that a ‘new’ financial assets handling system only has a meaning if beyond bringing blockchain-enabled capabilities it changes the game regarding costs. Considering we have customers doing STOs of all sizes, we needed to make the platform as self-serviceable as possible to reduce costs while providing high-quality. In the end, we’ve managed to literally slash these costs.Question 6.How does Talium clear STOs for The Howey Test and would Wanchain investors be beneficiaries of . equity, dividends, profit share rights, voting rights, buy-back rights, etc. Since the tokens are deemed to be a security, they are subjected to various SEC regulations and federal securities. It can be said that tokenized securities are a digital form of traditional stocks running on the blockchain with compliance rules integrated into the token itself. ?Julien: Well, that the role of the issuer to clear the howey test. We provide a rule engine to clear those tests !Question 7.General question to both What advantages would replacing the traditional stocks with the digital blockchain system give us?Julien: Easy transferability, low infrastructure cost, easy access to STOs (easier than IPO) and regulated environnement in many countries now (ownership of a token recognized as ownership of the underlying Securities). Transparent and easy way to calculate dividends/coupons and faster to handle corporate actions (voting, and so on).François: Also: solves delay issues (sometimes huge), and adds liquidity. Much easier and cheaper for issuers, and makes investments more promising to investors.Part 2: Where traditional share markets are off on weekends and close at 5 pm, the security token space remains active as long as the blockchain is active, i.e. 24/7. This huge digital advantage opens up an array of opportunities for investors and businesses alike how do you see this opportunity play out with your partnershipJulien: Right, and this is where full automation of compliance has a role to play. If you’ve not fully automated compliance rules, then there should be a manual (human) clearing process. For this purpose, we’ve implemented a Domain Specific Language to express compliance rules in an easy way, and a way to upgrade them without having to ask an engineer to deploy a new version of the smart contracts.Question 8.How would Talium envision leveraging Wanchains crosschain technology such as the the two way bridge can you see STOs being issued on various tokens via Wanchains platform and how would you see that play out over timeAs already mentioned, security tokens are truly securities and are subject to various regulations and federal restrictions. To code all of these regulations in a smart contract can sometimes become strenuous given the complex intertwined set of regulations. How does Wanchain seek to overcome this ?Julien: Yes, cross-chain tokens is a very interesting feature. That requires a bridge able to handle that on both sides. We could do that if there’s a need to. It means having escrow contracts on both sides (eg. ERC-1400 <=> WRC-1400 escrows).Question 9.What is going to be THE standard that will be adopted for issuance and management of security tokens? How do we list these tokens in exchanges or the secondary market?Julien: Great question. A standard is a standard if it is used by the majority. We’ve found it interesting to use the ERC-1400 because there was a community around it and a lot of work has been achieved around it on many real use cases. The standard included : partial fungibility (partitionning), custodial ownership, operator/controller transfert, documents attachments.Question 10.Great Q&A! I am wondering how does the platform select project to launch STO and how to avoid investors being scammed? After the STO, where can the tokens be exchanged? Thanks.Julien: Thanks for your question. As a tech provider, we do not provide due diligence services but we work with companies doing it and we provide investors with ‘marks’ and the name of the company having audited the issuer + operation.Question 11.If i did understand correctly wanchain will be the second blockchain after ethereum, to integrate your platform with. Can you tell us about your sto experience on eth up till now, and will you continue to use eth (if you did already) and expand to other blockchains as well?François: Thanks for your question. First you should understand the platform enables to adresses intermediaries (private banks, accelerators, etc.), who themselves can adress financial asset issuers… or other intermediaries. We can do that because our implementation segregates each ‘tenant’. This results in absolute scalability. So today, our STO customers are either intermediaries or direct issuers. We have intermediary partners over Africa for 30ish countries, others active worldwide, some focusing with Switzerland, and obviously in France. We also have issuers as customers in France and Switzerland. More to come. STOs are a new market, but things are moving very fast. Also… the platform is blockchain-agnostic by design, compatible by default with all EVM-compatible blockchains. So that’s more like 15+ compatibilities.Question 12.Now that Polymath is moving to another blockchain, will another project lead the ERC1400 initiative? Or is Polymath still leading?Julien: Adam Dossa (Polymath) told that ERC-1400 will still be the standard for Eth and they develop Polymesh in parallel for specific purposes. It’s community driven, Polymath is very involved and Consensys is using it too , among many others.Question 13. What is difference between WanChain DeFi to other DeFi Plattforms?Jack: Wanchain is one of the first decentralized cross-chain DeFi platforms in the space. Tokens on other chains can be moved to Wanchain to buy assets such as STOs. On the other hand, assets can be moved to other chains to participate in other markets…François: Thanks The Rock for the question. The WanChain DeFi platform notably benefits from Real compliance capabilities. Compliance is handled offchain with certificates provided through a compliance engine; the possibilities are limitless in terms of rules to be used: onchain, offchain, coming from an API, live (versioned), handling actual complex associates’ pact rules, etc.Question 14.Hi Jack. Arent you afraid that working actively towards fundraising on your blockchain, this might hurt one day relationships with china officials?Jack: There shouldn’t be any problem if the funds are raised from investors from outside of China. And China is going to be more friendly toward the blockchain space. As long as we comply with the policies, we should be fine.Part 2: Thank you Jack. So fundraising for chinese companies also shouldnt be a problem, as long as the funds come from outside?Jack: Through certain structure such as VIE. Also qualified Chinese investors are allowed to invest in foreign companies.Question 15.What are the main obstacles that could face the STO industry going forward? can we expect more and more strict regulations all around the world?Julien: Well, STOs are regulated as standard instruments by financial markets authorities. The only thing we hope is that there will be improvements or simplifications related to secondary markets. I mean, right now if you want to provide a trading venue you have to be an ATS or MTF. Also, laws have to be adapted regarding settlement activities wrt responsibilities in a decentralized environmentQuestion 16.Hi Jack, will wanchain consider also some form of crosschain that directly transfer between two non-wan chains, for example, BTC to ETH? I think there are considerable number of people who may not want to move assets to wanchain, but are very much interested in crosschain transaction.Jack: Yes, that’s exactly what we are working on.Thank you to the guests of the AMA — François de Chezelles, Julien Brodier and Jack Lu. Also thank you to everyone who participated and/or is reading right now. Until next time!About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Decentralized No-Loss Lotte...

The new Wanchain DApp is now available online and through the DApp store in the Wanchain Desktop Light WalletJack’s Pot is the newly launched Wanchain based no-loss lottery DApp inspired the Ethereum based no-loss lottery DApp, Pool Together. The DApp is a collaboration between the Wanchain and FinNexus dev teams and will be operated by FinNexus. As in Pool Together, Jack’s Pot allows DApp users a chance to win a lottery prize by staking their cryptocurrency (in this case, WAN). The staked WAN is delegated to a Wanchain validator, generating rewards as a part of the consensus process. The rewards are then pooled together in a single pot and awarded to the lottery winners.No-loss, risk free lotteryUnlike a typical lottery where you lose the funds spent on tickets, with Jack’s Pot, your initial funds are never at risk. By generating the prize pot through delegation rewards from Wanchain’s consensus mechanism, Jack’s Pot allows for a no-loss lottery. Similar to a prize-linked savings account, the DApp is a fun and risk free way to play a game of chance and save your WAN at the same time.How to playTicket selection areaYou can access Jack’s Pot either through the web interface or through the Wan Wallet DApp store. You can download the wallet from the Wanchain home page at https://www.wanchain.org/getstarted/, and you can find wallet guides at http://wanchain.guide/ and http://explorewanchain.org/.The See this video guide for how to add a DApp in the Wan Wallet DApp store.Unlike Pool Together, Jack’s Pot gives users the chance to choose their own lucky number. To get started playing, users buy tickets with four digit numbers of their choice, and all users who pick tickets with the correct four digit number will win a part of the prize pot.Lottery number selectionYou can also choose for your lottery ticket numbers to be randomly generated if you don’t want to choose your own number. Simply choose how many unique random number tickets you wish to generate:Random number ticket generatorEach lottery round lasts a single day, and winnings are distributed 23 hours after the end of the round. If no player chooses a winning number during a round, the pooled WAN carries over the next round. If you wish to keep playing, simply leave your WAN staked in the game.You may stop playing the game at any time by selecting the tickets you wish to withdraw and clicking the ‘Withdraw’ button:The ‘Withdraw’ buttonJack’s Pot uses a liquidity pool which allows for instant withdrawal (ordinarily, unstaking WAN can take up to 3 days). Generally speaking, withdrawal will be instant, although in cases of large numbers of withdrawal at one time, there may be a delay up to 3 days.We hope you enjoy the game, let us know your thoughts on Twitter and Telegram!About WanchainWanchain is the infrastructure connecting the decentralized financial world.

STO Platform launches on Wa...

Wanchain is extremely delighted to announce a partnership with the French securities and Software as a Service (SaaS) company Talium with the launch of the first Security Token Offering (STO) platform on Wanchain. Before diving into the platform release and technicalities behind it, let’s talk a little about the leading platform partner, Talium.What is Talium, and who is behind it?An Oracle Innovation Partner of the Year (2019), Talium was co-founded in 2012 by MIT alumnus François de Chezelles(CEO) and applied cryptography specialist Julien Brodier (CTO). It initially provided traditional software and systems engineering services to multinational corporations, including but not limited to Airbus, CMA CGM, Atos and Amadeus, Focused on state-of-the-art technologies, it developed blockchain integration expertise along with 15+ projects since 2015, as well as confidential computing in-depth know-how.Partner of the Year Innovation (Oracle)Talium was one of the very first to develop and have a consortium blockchain project to go live, thereby implementing a full production-grade decentralized blockchain infrastructure (with Hyperledger Fabric), even before any Blockchain as a Service offer (BaaS) ever existed. This project deployed IoT-based P2P sharing of solar energy for French startup Sunchain. Another project of interest was for French startup BCdiploma, where Talium combined cryptography and a blockchain-agnostic architecture to save certificates directly onto blockchains while enforcing GDPR’s right to be forgotten.Eventually, Talium developed unique skills to bring added value by combining blockchain with advanced data protection and confidential computing techniques. One such project ended up as an IBM Use Case. The use-case was in close collaboration with IBM’s US Cloud Security R&D team to use Fortanix’s revolutionary runtime memory encryption technology. This technology simplifies the usage of Intel’s enclave technology embedded in most Intel processors, namely Intel Software Guard Extensions (SGX). Talium could then build a robust, fast, and scalable SaaS software while maintaining at all times strict security of the confidential data, private encryption keys included. This project, conducted for French P2P energy marketplace provider Irene Energy, used the Stellar network to allow near-instant micropayments while having crypto wallets in an “untrusted” cloud environment.Irene Energy, IBM, Talium & FortanixDigital Securities management “Talium Assets”After having designed, integrated, and distributed several Utility Tokens, Talium started in 2018 the creation of a Digital Securities management framework called Talium Assets. Talium Assets provides investment intermediaries with a tool to build custom marketplaces for the distribution of financial instruments, and issuers with a compliant platform to raise funds (STO) or digitize their corporate governance.Going forward, aside from the STO platform (which we will go over in a bit), Wanchain has been putting more resources into its suite of private blockchains “Lanchains.” A hybrid system is required to tackle the blockchain scalability trilemma termed by Vitalik Buterin. The scalability trilemma (decentralization, security, and scalability) reflects the trade-offs or the “opportunity cost” that projects undergo when making structural changes to their blockchains. You cannot have a fully decentralized, fully scalable, and fully secure blockchain network, you have to combine elements from the centralized world with elements from the decentralized world, the new digital economy.Decentralized: No central point of control (not the same as the central governing entity).Scalable: Blockchains that can handle vast increases in network growth over time.Secure: Resilient in technical infrastructure. Ability to combat bugs and other unforeseen events expectedly.Bridging legacy with blockchainYou might be asking why this is related to the STO announcement. Well, because it is essential to understand why and how we combine these separate worlds (traditional financial world to this new web, 3.0). The decision-makers in the conventional business world are facing increasing pressure from shareholders to invest more in technology as technology is exponentially growing thanks (or no thanks) to what we understand simply as Moore’s Law. Although intel co-founder Gordon Moore did not come up with the term “Moores Law,” it has become a golden rule in our society with time. Moore just made a statement based on his findings with the intel chip manufacturing over the years. Moore’s law refers to the “number of transistors on a microchip double every two years, though the cost of computers halves.”Timing is crucial, and we’ve identified security tokens as a significant component of the growing new digital economy. We want to be part of this new revolution from the start and in every capacity. With the increasing technology demands and the pressure we’ve received from partners in Canada and parts of Europe, this security token offering platform is the only the first chapter of the STO book. As well as inside the crypto space, we have to keep up with new advancements outside of the blockchain industry and lead the way in decentralized finance interoperability. Which also means interoperability between legacy systems and blockchain networks.Chapter 1 — The Platform: Wanchain components, and the Off-Chain componentsTalium has developed a blockchain.-agnostic & modular Security Token issuance solution which integrates all of the tools necessary for a compliant and robust security token issue, including:Tokens “pad” and “designer” dashboard.The security token issuance will happen on Wanchain’s public blockchain. Although not defined yet, we are looking into the WRC1400 standard. Credit goes to Polymath for creating this standard on Ethereum “ERC1400”).KYT — (Know Your Transaction) ”KYT is to identify potentially risky transactions and their underlying unusual behavior for detecting money laundering, fraud, or corruption.” More granular and trustworthy than standard yearly KYC/AML checks.Integration of crypto and fiat payments, directly or via PSPsInvestor documents with completely verifiable-digital signaturesA dynamic compliance rule engineHold up, not so fast! Can you explain what security tokens are first?In traditional finance, securities are defined as “ownership in a publicly-traded corporation” or “ownership represented as an option.” So what are security tokens? With the above illustration, a security token is the same, but the ownership information of this investment product stored on a specific blockchain. So Security Token Offerings are very different from Initial Coin Offerings. ICOs gave rise to “utility tokens,” which have a particular purpose and requirement when leveraging tools and decentralized applications on a specific blockchain. Like in the case of “WAN” or “Wancoin,” it is required for transactions, delegation on the proof of stake platform, setting up smart contracts, deploying new tokens, and for cross-chain transactions and storemen node incentive mechanisms. This is structurally and fundamentally different from a security token, which is an investment product governed by security laws in particular regions and has a dividend structure tied to it. To better understand how STOs differ from IPOs, we will use the illustration below designed by Cointelegraph.Source — How is an STO different from an IPO?Now that you have a better understanding of what STOs consists of, we will share some details about the platform launching on Wanchain (first on testnet with a mainnet launch shortly after).Creating an STO operation (screenshots of v1. platform)Defining the token and operation type (ICO, STO)Defining the jurisdiction, start, and end date, currency, and capsMinimum and maximum allocations for investorsChoose whether it is a public or private operationThe beauty of this is what we referred to before as “bridging legacy with blockchain”. We are able to issue the security tokens on Wanchain in their WRC1400 standard (or another security token standard, depending on the issuance partner) while keeping all of the investor documentation and details, secure and protected in an off-chain database thanks to Talium’s state-of-the-art security and compliance platform.Concrete details about the first STO launches are expected by the end of the year, with a focus on more partnerships, exchanges, enterprises, and integrations in the STO space in the coming months. Aside from this, we have prepared a series of community events with our partner so you can take a deep-dive into what will soon become one of the leading STO platforms in the industry.Community Events with TaliumThis is the first part of our STO announcement. In the next 3 weeks, we will be hosting various engaging community activities so you can learn more about our partner and the implications behind this launch.Today: STO Partner description and STO platform overview.Next week: Telegram AMA with Talium’s CEO & CTO and Wanchain’s CEO, Jack Lu.3rd week: Chapter 2 of the announcement, featuring more details about the platform and Talium STO use-cases on Wanchain.4th week: Live Zoom demo of the Talium platform with the Talium executive and development teams.Stay tuned for our Chapter 2 STO release next week.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

DEXes Galore! WRDEX and Bit...

The two newly launched decentralized exchanges are both built using the WanDex framework, and share liquidity to ensure a smooth trading experienceRapidly Expanding Wanchain DApp EcosystemDecentralized exchanges WRDEX from Wanchain ecosystem project RiveX and Bitlly DEX from previous Wanchain collaborator Bitllywood are the two newest DApps to be added to Wanchain’s rapidly expanding DApp store. The DApp store, which is available through the Wanchain official desktop wallet, hosts decentralized applications (DApps) which run by third party operators and built on top of the Wanchain blockchain. The DApp store launched recently with the Wandora Box DApp (video guide) from Wanchain ecosystem project FinNexus, and is set to continue expanding further.“Wanchain’s development of decentralized crosschain technology makes the crosschain DEX possible for the first time to crypto users, and in the near future, we plan to launch the Wanchain DeFi Global Partner Program which will allow partners in different parts of the world to easily operate DeFi businesses such as crosschain DEXes, no-loss lotteries, P2P private exchanges, crypto options etc' by working together with Wanchain“— Lini, Wanchain VP of BusinessWRDEX and Bitlly DEX in the Wanchain Desktop Wallet DApp Store“WRDEX is a revolutionary DEX which incorporates shared orderbook and liquidity from a CEX while staying decentralized. The outreach to WRDEX will increase as it is now available in Wanchain’s DAPP store.” — Mark Tan, RiveX Co-founderBuilt With Wandex — Shared Liquidity, Crosschain, Highly ScaleableThe Wandex framework builds on top of DDEX’s Hydro Protocol with a variety of modifications and improvements. It includes front end, wallet, and smart contract modules. There are three features in particular which make Wandex an excellent solution if you’re considering setting up a DEX: shared liquidity, crosschain features, and high scalability.Shared liquidity — Wandex operators may choose to take part in a shared liquidity pool. This means that different DEX operators can all benefit each other by increasing the liquidity pool and ensuring that all Wandex DEXes can offer a smooth trading experience.Crosschain features — Wandex supports the trading of all crosschain assets currently available on Wanchain, including ETH, BTC, EOS, and a number of mainstream ERC20 assets. Wanchain is continually adding to its list of supported crosschain assets, so expect to see this list growing. This enables for the decentralized and permissionless trading of assets on different chains, something which was previously impossible (generally only centralized trading of assets from different blockchains has been done until now).High scalability — Wanchain currently features speeds of over 2000 transactions per second, which means Wandex is highly scalable and can handle high volumes of rapid trading.Decentralized Crosschain DEXes — an Essential Part of Wanchain’s Ultimate VisionWanchain’s ultimate goal has always been to allow for value to flow freely between chains, and to support the establishment of complex crosschain financial applications. In the last several years, the Wanchain team has been hard at work and focused on building the core infrastructure for the crosschain transfer of value.The establishment of the first few crosschain DEXes on Wanchain marks a big step in moving forward from the development of core infrastructure towards the development of end user facing applications. While they were previously forced to use centralized services, now with DEXes built with Wandex individual users can finally trade assets from different chains in a permissionless and decentralized manner.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain To Join Band Proto...

Wanchain is officially set to join Band Protocol as a genesis validator as they ramp up towards their mainnet launch of BandChain, an independent blockchain built specifically for oracle computations that will enable real-time data requests to be made on-demand.Band Protocol is a blockchain agnostic decentralized oracle services provider that connects decentralized applications to any external data source or API in a scalable and trustless manner. They are supported by a number of leading crypto industry organizations including Binance, and prestigious institutional investors such as Sequoia Capital.“Band Protocol looks forward to having Wanchain join the BandChain ecosystem as a genesis validator, extending mutually beneficial collaborations in our strategic partnership. We are excited to see Wanchain’s rapidly growing ecosystem and continue to provide support through decentralized oracles as the reliability and security of off-chain data becomes increasingly important.”Soravis Srinawakoon, CEO & Co-Founder of Band ProtocolBand Protocol’s oracle services bring useful off-chain data such as price feeds, sports events and lottery outcomes, and more to Wanchain. They are currently being integrated as the data source for Wanchain ecosystem project FinNexus to leverage real-time price information, greatly expanding the use cases FinNexus is able to support while ensuring that reliable, high-quality data is being utilized.FinNexus Forms Strategic Cooperation With Band Protocol To Power Its DeFi DApps and Tokenized…Mutually Beneficial CooperationWanchain is joining Band Protocol as a validator node to further strengthen ties between the two ecosystems. Band’s valuable oracle services bring a wide range of essential off-chain data to Wanchain’s DApps, while Wanchain’s ecosystem projects provide use cases that require a trustworthy decentralized oracle. For example, FinNexus is now able to consume price data of any traditional financial products to create token-backed assets, greatly expanding offerings and flexibility of the protocol.“We’re really excited about the new possibilities Band Protocol v2 will bring to Wanchain DApps including real-time data connections to any data source or APIs. We are confident in their ability to become a key player in the oracle space and will be supporting their mission as a genesis validator on the BandChain network.Jack Lu, CEO & Founder of WanchainA Key Part of Wanchain’s Rapidly Growing EcosystemThe last few months have seen the rapid development of the Wanchain ecosystem, especially from two of Wanchain’s most prominent projects, RiveX and FinNexus. RiveX is hard at work on its cross-chain decentralized exchange WRDEX, and FinNexus has released the prediction game Wandora Box with their token sale just around the corner. As the ecosystem grows, the integration of off-chain data becomes increasingly important, and Band Protocol is set to take on that vital role with their real-time, scalable, and blockchain agnostic solution.About Band ProtocolBand Protocol is a cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. Blockchains are great at immutable storage and deterministic, verifiable computations — however, they cannot securely access data available outside the blockchain networks. Band Protocol enables smart contract applications such as DeFi, prediction markets, and games to be built on-chain without relying on the single point of failure of a centralized oracle.

A Chat with RiveX about WRD...

We sit down with RiveX cofounder Mark Tan and cofounder & CEO Alex Ng to discuss RiveX’s work on WRDEX, the first Wanchain Cross-chain DEXWRDEX (Testnet) from Wanchain Ecosystem Project RiveXRiveX is a Wanchain ecosystem project which was founded by previous Wanchain Asia business development director Mark Tan along with RiveX CEO and co-founder Alex Ng. Mark is a finance and blockchain professional with almost a decade of experience working in finance and blockchain. Alex has a strong technical background with a degree in Electronics and Communications Engineering and over half a decade’s worth of experience working at Dell.RiveX is focused on building second layer solutions for Wanchain, and is currently building a decentralized exchange called WRDEX (Currently on testnet) on Wanchain using Wandex, Wanchain’s cross-chain DEX SDK. On April 3rd, 2020, we sat down with Mark and Alex for a chat about WRDEX.What is Wandex and how is RiveX using it?Mark Tan — “Wandex is an initiative launched by Wanchain to promote interoperability and the use of cross-chain technologies between different blockchains. Wandex is solely responsible for the technical aspect of things while there can be many operators operating the DEX under their own brand. Think of Wandex as an airport while there can be many airlines operating in the said airport. There are other protocols that are similar to how Wandex works, for example, Loopring, Hydro Protocol etc. RiveX is one of the operator under the brand name, WRDEX. RiveX is utilizing Wandex’s blockchain assets cross-chain capabilities as a core.”Charting and orderbooks are two functions provided by WanDexWhat are the differences between core Wandex and WRDEX?Mark Tan — “Wandex is solely a tech provider, providing the cross-chain technologies to all the operators under Wandex. On the other hand, WRDEX is utilizing the cross-chain technologies provided by Wandex and has its own innovative strategies by exclusively listing projects within RiveX’s ecosystem, structured and derivatives tokens trading which will commence in Q2 2020, a UI which will be different from Wandex (launching in Q2 2020) and further WRDEX features enhancement which will be progressively happening from Q2 2020 onwards.”The Testnet Version of WRDEX, available to try hereWhat makes WRDEX unique?Alex Ng— “WRDEX is different from other DEX as it has cross-chain capabilities, structured and derivatives trading and trading experience which operates as a centralized exchange instead of a P2P-style. The cross-chain functionality is particularly unique since it allows for a decentralized settlement of each WRC20 asset back to its native chain without having to go through a trusted third party as one might have to with ERC20 WBTC or other current implementations of ERC20 cross-chain wrapped tokens.”Can you tell us a bit about the WRDEX team?Alex Ng— “The WRDEX team consists of people from a diverse background who has working experience in quantitative and algorithm trading, centralized cryptocurrency exchanges, investment banking, and blockchain development. The team has a good mix of talents to ensure the longevity and smooth operations for WRDEX.”How does WRDEX fit into RiveX’s big picture plan?Mark Tan — “RiveX itself is embarking on two major pillars which are decentralized finance (DeFi) and enterprise solutions. RiveX Wallet aims to be a dApp superhouse where it houses dApps within RiveX’s ecosystem and dApps from other ecosystems as well. The team major focus now is DeFi. WRDEX is the first DeFi decentralized application introduced within RiveX’s ecosystem. WRDEX is also being built and integrated into RiveX Wallet.”When will WRDEX be live?Alex Ng— “WRDEX will go live and be on main-net in April 2020. The RiveX team will only be doing a soft-launch for now as requested by the RiveX’s investors and community. An official launch will take place after RVX is listed.”What trading pairs will there be?Alex Ng— “The current trading pairs will be WBTC/WUSDT, WETH/WUSDT, WEOS/WUSDT, and WWAN/WUSDT. There will be more pairs being listed in the near future. The structured and derivatives trading products will be available only after RVX is listed.”Cross-chain trading on WRDEXHas Coronavirus affected development?Alex Ng— “We will be lying if we say that the virus has not affected us. It did not affect us much but it did cause a little slowdown in our organization’s sentiment. However, things are still progressing as per our investors and community expectation. We cannot wait to push WRDEX live and celebrate this joyful moment as the first DEX operator for Wandex. This is indeed a celebration for Wanchain’s ecosystem!”About RiveXRiveX is a scalable layer-2 on-chain and off-chain solution on Wanchain protocol and private chains. Combining the strength and virtues of both public chains and private chains to empower a scalable enterprise economy and decentralized finance. RiveX has its very own APIs & SDKs to allow developers to build on RiveX and also allows the ease of integration for any enterprises and applications to be integrated into RiveX’s infrastructure.More about RiveXWeb | Twitter | Telegram | LinkedIn | GitHubAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

Interoperable Toilet Paper ...

Interoperable Toilet Paper — Wanchain Integrates Cross-Chain TPT!“Your right to wipe, now tokenized,” and now with cross-chain interoperability!On April 1st, 2020, the Wanchain team is thrilled to announce the cross-chain integration of Toilet Paper Token (TPT) on the Wanchain mainnet. WTPT has been launched on the Wanchain mainnet and users may now manage the TPT and cross-chain WTPT tokens on their official Wanchain wallet.What is Toilet Paper Token?Toilet Paper Token is the second largest cryptocurrency by market capitalization after Bitcoin. Holders of the TPT token are guaranteed access to toilet paper rolls at a stable price in TPT tokens. By purchasing TPT tokens users are protected from the volatility in the price of toilet paper due to destabilizing world events.Interoperable Toilet PaperIn the real world, toilet paper is being hoarded, and cannot flow freely within the economy. Similarly, TPT token is restricted to the TPT chain, and its value is siloed. The cross-chain connection of TPT token on Wanchain allows for the value of toilet paper to flow freely between chains. No longer will toilet paper be locked to one chain alone.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain ecosystem project ...

Wandora Box is the first DApp game to hit the Wanchain mainnetWandora Box hit the Wanchain mainnet on March 30th, 2020, as the first ever decentralized prediction game to launch on Wanchain. Wandora Box is a fun, fair, and simple game where users can win prizes by correctly predicting the price trend of WAN/BTC over a period of time. Any user who makes a correct prediction will win a prize. As a fun additional twist, all users who make a prediction will be enrolled in a lottery where they have a chance to win another prize, regardless of whether or not their prediction is correct.Play now!You can play the DApp now here. (Compatible with the WanMask Chrome extension). Keep reading below for more instructions about how to play.6000 WAN In rewards for early participants!To reward early users of Wandora Box, the FinNexus team is offering 6000 WAN in prizes!The specific event details and participation methods was announced on FinNexus’s Medium, so check it out and also follow their Twitter so you can know more updates.Wandora box: How to playWandora Box is currently compatible with WanMask. A new version of the Wanchain desktop light wallet will be launched in early April with direct support for Wandora Box. And Ledger and Trezor will also support for Wandora Box then.You can select your wallet at the Wandora Box app main page:To play, you choose an amount of WAN to place on your prediction, and your prediction of the price movement of the WAN / BTC trading pair (either UP or DOWN).Wandora Box issues prizes every 8 hours, at 4 am, 12 noon and 8 pm (Beijing time — UTC+8).At the end of each round, the prize pot will be divided amongst those who made correct predictions according to the the ratio of the amount each user placed on their prediction vs the total amount placed by all other users who made a correct prediction. (ie, if you placed 2 WAN and made a correct prediction, and the total amount placed on correct predictions including your 2 WAN is 20 WAN, then you will get 10% of the prize pot). The WAN will be automatically transferred to the player’s wallet address.Extra Lottery GameIn addition to allowing players to participate in predicting price changes to win rewards, Wandora Box also allows players to play another game simultaneously, a prize lottery. Players will automatically be entered in the lottery regardless of whether they guessed the WAN price UP or DOWN. The winners will be awarded the WAN in the lottery pool.Note: Each time a player makes a prediction of UP or DOWN, 90% of the bet amount will go to prediction prize pool, and 10% will go to the lottery prize pool.For a detailed guide to the rules of the game, see the documentation on Github:Game results determined by a fair and verifiable random number generation algorithmIn Wanchain’s PoS Galaxy Consensus mechanism, the Wanchain research team has introduced a secure and efficient random generation algorithm. The Wandora Box game uses the random numbers generated as part of Galaxy Consensus to determine the results of the lottery.The random number generation algorithm used in Galaxy Consensus complies with the 6 key elements of true random number generation:The Six Elements of A Good Random Number Generator:Decentralized: If the random number generation process is decentralized, you do not need to rely on a trusted third party.Unpredictable: It is impossible to predict future random numbers based on historically generated random numbers or other information. This is the basic requirement of “randomness”.Unbiased: No one can use the computing power or latecomer advantage to target the random number generation result.Uniformity: The output random number is uniformly distributed in its range.Guaranteed Output Delivery: Participants in the random number generation algorithm cannot make it impossible to output random numbers by violating the algorithm, that is, random number output is bound to occur.Publicly Verifiable: Nodes that are not involved in random number generation can monitor the implementation of the protocol in a posteriori manner to verify that the random number is credible and unbiased.Therefore, the random number generation used to determine the winners in Wandora Box is safe, fair and publicly verifiable.About FinNexusFinNexus is building an open finance protocol to power hybrid marketplaces that trade both decentralized and traditional financial products. The FNX token will live on the Wanchain blockchain to take advantage of the most robust cross-chain capabilities currently available in the industry.

Strategic Cooperation Estab...

The China Based Blockchain Platform Leverages Wanchain to Protect Intellectual Property Related to FilmsIn March of 2020, Wanchain has reached a strategic cooperation with Bitllywood, the Beijing based film IP blockchain services provider.The two parties worked together to establish a blockchain based model for the protection of intellectual property related to film and television.The model works to realize the protection of various forms of intellection property including video, images, music, text, and other formats, and to allow for the blockchain based circulation of such intellectual property.Under the universal cross-chain framework of Wanchain, film and television IP assets will be allowed to circulate freely between different public and consortium chains, greatly increasing the liquidity of IP assets.Major Chinese media site Xinhuanet reported on the cooperation and new model of IP protection in a March 17th article:What is BitllywoodBitllywood is a decentralized platform for the protection of film and television IP using on-chain certification.Latest Bitllywood film with on-chain IP protection, “Nihao, Edwin”As China places more and more importance on the development of high-tech industries and the application of blockchain technology, Bitllywood has adopted blockchain technology at its core, adding an important piece to the legal compliance of film and television copyright. Bitllywood is committed to building a blockchain based ecosystem for film and television creators.For more information, please navigate to the Bitllywood official website.IP Market Current Situation in ChinaCurrently, the process for IP authorization and storage of certificates is complex and not transparent. The maintenance of copyright in film and television IP is difficult and costly, and the procedures are cumbersome. The these difficulties have led to inefficient IP markets, and a great loss of potential value.Bitllywood aims to address this problem. Through the cooperation with Wanchain, Bitllywood has now implemented “one-click” on-chain permanent storage of IP certificates, and will resolve IP authorization through smart contracts.“the market for film and television IP is huge and has potential. Unfortunately, there are no good market regulation in China, which makes value creation based on IP difficult” — Bitllywood founder Robin LuoBitllywood will use blockchain technology for the storage of film and television IP, to protect IP intellectual property rights, and to trigger authorization and copyright transactions related to IP.China’s film and television IP market is about to usher in its golden age. In recent years, more and more high-quality film and television IP have appeared in China. Aided by the rapid development of the Internet and blockchain technology, the IP industry is prepped for geometric growth.Cooperation between Wanchain and Bitllywood“Quality IP assets should be protected, discovered and circulated, and blockchain technology will empower future quality creators, reduce their investment costs and let them focus on content creation.” — Robin Luo, founder of BitllywoodBitllywood aims to promote the accelerated integration of blockchain for the IP industry, making the IP market more dynamic and expanding monetization channels.From left to right, Robin Luo, founder of Bitllywood, with Li Ni, global vice president of Wanchain, and Huang Chao, COO of BitllywoodWanchain, as the blockchain technology provider, is focused on building the world’s leading distributed cross-chain infrastructure. With the help of blockchain’s properties of decentralization, anti-tamperability, and traceability, Wanchain will help Bitllywood implement blockchain based IP certification, IP transfer, and chain management.In the future, the two parties will work to implement the free circulation of IP assets between different public and consortium chains through T-Bridge, Wanchain’s universal cross chain framework.“Due to the continuous evolutionn of technology, we have now reached the stage where blockchain technology will truly serve the real economy. We are very happy to see that Bitllywood chose Wanchain as a technology partner and are looking forward to providing a new blockchain-based scenario for the IP industry in China and even globally” — Li Ni, vice president of WanchainAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain Full Node Wallet (...

Wanchain Full Node Wallet Is Officially DeprecatedThe Wallet Will Continue to Function Normally, But We Recommend You Switch to the Light Desktop Wallet, See Instructions BelowDear Wanchain Community:Due to the increased block height and longer sync up time of the full-node wallet, the Wanchain team is suspending development of the Wanchain Full-node wallet, and it will no longer receive future updates.As of April 2nd, 2020, Wanchain Full-node Wallet be permanently removed from the download resources of the Wanchain official website, however it will continue to function normally.The Wanchain Full-node Wallet files will still be available on Wanchain’s official Github, but we do not encourage its use.We strongly recommend that users instead use the Wanchain Light Wallet or Wanchain Mobile Wallet. The following steps tell you how to import the Keystore file with your WAN assets included from the Full-node Wallet to the light wallet.Recommended Method — Generate a New Account in the New Wanchain Light Wallet and Transfer All Your Assets from the Old Desktop WalletNavigate to the Wanchain.org — Get Started page and download the Desktop Light or Mobile walletFollow the in app instructions for creating an account, make certain to save your pass phrase in a safe place.Use your old Desktop wallet to transfer your WAN and WRC-20 assets (WBTC, WETH, etc.) to your new Wanchain address which you created in the Desktop Light wallet.Transfer ETH, ERC-20, and BTC to the newly created accounts in your Desktop Light wallet. Make certain to send native tokens to their native chains: i.e., ETH and ERC-20 to your Ethereum address, and BTC to your Bitcoin address.Once you have transferred all your assets to the newly generated accounts in the Desktop Light wallet, you are finished. All your assets can be backed up and restored using your passphrase which you generated with the Desktop Light wallet. (Please do note that the passphrase can not be used to back up or restore any assets in the old Desktop wallet).Discouraged Method — Import Keystore File From Wanchain Full-node Wallet To Wanchain Light Wallet(This method is discouraged because any accounts imported by keystore file will not be backed up with the passphrase you generated in the new Desktop Light wallet.We strongly recommend instead that you follow the previous method of transferring all assets to newly generated accounts in the new Desktop Light wallet)1. Find the Keystore FileFirst, find the Keystore file in the installation path of the Wanchain Full-node Wallet.Please note that the wallet supports both testnet and mainnet. You need to make sure that keystores for the same network are copied. The keystores files for testnet and mainnet are in different directories.IMPORTANT NOTE:Back up your keystore files in a safe place, they are the only way to recover your account. You will need to use this keystore to recover your account every time reinstall the Wanchain wallet. Your passphrase on the Light Wallet will not recover accounts which were generated in the old wallet. Alternatively, you can simply transfer your assets to an account generated with the Light Wallet.Open the Full-node Wallet, find File->Backup->Accounts, and find the Keystore fileIf your Wanchain Full-node Wallet fails to open, you can find the Keystore file directly through the pathPath in Windows:\Users\xxxx\AppData\Roaming\wanchain\keystorePath in Mac:/Users/xxxx/Library/wanchain/keystorePath in Linux:/home/user/.wanchain/keystoreThe Keystore file is shown as follows:2. Import Keystore FileSecond, open and log in Wanchain Light Wallet, and click on Asset->Wanchain->Import Keystore File3. Input PasswordsThird, in the pop-up dialog window, input the password of your Wanchain Full-node Wallet, the password of current Wanchain Light Wallet, and load the Keystore file you want. Click on Submit.Click on Wallet->WAN on the left panel of Wanchain Light Wallet, you can see the Keystore-related WAN address and the WAN balance of this address.IMPORTANT NOTE: If you choose this method, it is important that you save BOTH the passphrase you generated in the new Desktop Light wallet and also the Keystore file from the old Desktop wallet in order to make certain all your assets are backed up. We therefore strongly recommend you choose the previous method for switching wallets.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Cross-chain EOS Has Hit the...

We welcome the EOS community to use WEOS through the Wanchain official wallet and for developers to learn more about how this release connects EOS to the rest of the blockchain worldThe WEOS token is now available for cross chain transactions on the Wanchain mainnet! You can now manage your native EOS account including CPU, NET, and RAM, directly through the Wanchain wallet, and can transact with cross-chain WEOS tokens on the Wanchain Mainnet through the Wan Wallet’s cross chain interface.Click here to download the Wanchain Wallet 1.2.0 with cross-chain EOS support.Please join our Tech Support Telegram channel if you have any issues with the new wallet.The integration of WEOS to the Wanchain network is a major step forward for Wanchain. As the second largest smart contract and DAPP platform after Ethereum, EOS in an incredibly important segment of the public blockchain ecosystem, both economically and technologically. The Wanchain community looks forward to more interactions and integrations with the EOS community and ecosystem moving forward, and we welcome the EOS community and developers to work together with us! We encourage EOS users to check out the Wanchain wallet and explore both its EOS based functions as well as the WEOS cross-chain implementation on the Wanchain blockchain itself.We believe that the integration of EOS through Wanchain is just as significant to the Wanchain ecosystem as it is to the EOS ecosystem. This integration unlocks a wide range of new possibilities for EOS, as it is now possible for EOS to interact with tokens from other chains including WAN, BTC, ETH, and many ERC20 tokens. With a number of Wanchain based DEXes around the corner, it’s only a matter of time until EOS can be traded on decentralized platforms against other major cryptocurrencies. In addition to trading on DEXes, we envision a wide range of other possibilities which will be made possible through Wanchain’s cross-chain connection with EOS, and we look forward to exploring them together with the EOS community.The following sections are an overview of the new functions available in the Wanchain desktop wallet version 1.2.0, and remain mostly unchanged from the previous article on the testnet release of the EOS integration in version 0.0.99-beta.EOS in the Wanchain Desktop WalletOn the main EOS page you can view an overview of all you different EOS key pairs and accounts, as well as a summary of all the EOS and resources available in each account. At the bottom of the main page you can access the transaction history.EOS Main PageOn the transaction history page of the wallet you can view information about both normal EOS token and resource transactionsNormal Transaction History PageResource Transaction History PageOn the resource management page, you have full control over management of your EOS resources including RAM, CPU, and NET.

Wanchain 4.0 T-Bridge Frame...

Wanchain 4.0 T-Bridge Framework Tech Explainer: Part 1 — General OverviewHow the T-Bridge (Trusted-Bridge) Framework Enables Universal Blockchain Connections (Including Public-Private Connections)One of Wanchain’s core missions is to tackle the thorny problem of blockchain interoperability. The importance of cross-chain interoperability has only grown more apparent with the proliferation of different public and private blockchains. The problem is compounded by the fact that many popular blockchains are heterogenous (meaning they are built with fundamentally different technological architectures — consensus mechanisms, smart contract languages, etc.).As blockchain begins to gain more acceptance and institutional usage worldwide, more and more assets will start to move to private chains, as only they allow for the required controls needed to be legally compliant with various regulatory bodies around the world. The release of the Wanchain 4.0 and the T-Bridge framework fills this need and is currently the first and only standardized framework for which tackles the problem of private to public blockchain interoperability.In our Wanchain 4.0 release article, we announced the release of our new T-Bridge (Trusted-Bridge) framework, a general framework, and reference architecture with modular components and protocols which are compatible with Wanchain’s original Storeman cross-chain mechanism currently used for the public to public blockchain connections. The T-Bridge framework links components in a source chain, target chain, and routing chain together and defines standard components and protocols to enable cross-chain transactions (CCT). In this article, we give a broad technical overview of the T-Bridge framework.Meet The T-Bridge ArchitectJames Zhu: Wanchain Director of EngineeringThe T-Bridge framework was designed by the Wanchain Director of Research and Development, James Zhu. James is a graduate of the Peking University School of Mathematical Sciences with undergraduate and graduate degrees in information research and computer software. James has over 20 years of work experience in blockchain, big data analysis, internet and mobile platforms, distributed computing, telecommunications networking, SaaS platforms, and more. He held previous positions in Nortel Networks, Ericsson, Nokia, and several other high profile internet companies. He has carried out in-depth analysis and research on the technologies and scenarios of many major blockchain platforms and created Wanchain’s enterprise chain Lanchain product series and components.What Exactly is the T-Bridge Framework?The T-Bridge framework is a standardized, universal framework which allows for the exchange of assets and data between blockchains:Standardized — The T-Bridge framework is standardized according to specifications based on formal methods. This is a way to formally describe the framework specifications using a logically consistent language that allows for implementation in a wide variety of different computing environments and with various blockchains.Universal — This means that T-Bridge is designed to be implemented on any blockchain with smart contract capabilities regardless of its underlying technical design, such as consensus mechanism or smart contract language. This also means it allows for Public-Public, Private-Private, and Private-Public blockchain connections.Assets and Data — By this, we mean that the framework not only allows for the circulation of assets between blockchains (as Wanchain currently does now with Ethereum/ERC20 tokens, BTC, and EOS) but also allows for data to be shared between different blockchains. This allows for the creation of complex cross-chain decentralized applications where transactions on one chain can be triggered by events which occur on another chainHow Does the T-Bridge Framework Work?A simplified summary of how the T-Bridge framework works:The T-Bridge framework allows for users and service providers on different blockchains to engage in cross-chain transactions by interacting with smart contracts deployed on their respective chains. An intermediary router chain is used to register and sync necessary information related to cross-chain transactions. Protocol mediators monitor the state of different chains. They are able to issue transactions on one chain based on events that happen on another chain (this is roughly equivalent to the role of Storeman Nodes in Wanchain’s current solution for Public to Public cross-chain interoperability).Figure 1: General Overview of the T-Bridge FrameworkDefinition of Key Concepts and Actors:Router Chain (Chain Router in Figure 1): The router chain is the connecting hub for cross-chain transactions between business chains within the T-Bridge framework.Business Chain (Chains A and B in Figure 1): Business chains are involved in CCT transactions for providing related services or resources.Protocol Mediator (PM): The protocol mediator provides cross-chain transaction mechanisms across router and business chains via the T-Bridge framework. It monitors chains for aggregations and performs corresponding cross-chain transaction requests.Service Provider (SP): SP provides services or resources that are involved in cross-chain transactions.User (U): User initiates transactions for the exchange of cross-chain resources or services.CCT Contracts (Part of CCT contracts in Figure 1): CCT contracts provide the T-Bridge framework with various essential functions such as a cross-chain registry mechanism, supported trust models, basic CCT info, and more (The CCT Contracts will be discussed more thoroughly in Part 2).BIZ Contracts: The BIZ contracts provide essential services that supplement the core CCT Contracts. The BIZ Aggregation and BIZ Service/Pair Contracts will be discussed more thoroughly in part two.What does the T-Bridge Technical Stack look like?The Wanchain R&D team has provided the following possible technical stack for illustrative purposes:Figure 2: T-Bridge Technical StackThis is an abstracted depiction of the technical stack which does not specify exact technologies or implementation details. The details will vary from implementation to implementation. The T-Bridge proof of concept currently under development by the Wanchain team (more info about the proof of concept will be published shortly), makes use of Wanchain as both the router and business chain, and of Hyperledger’s Besu as a second business chain to be connected. Storage for the Chain Agent’s querying of blockchains is done with MongoDB, and ChainServices (not pictured in Figure 2) act as a supplement and improvement of ChainAgent for communication with blockchains which allow the Protocol Mediator to query blockchain info and send blockchain transactions. For more in-depth details about the proof of concept implementation, please stay tuned for the detailed specifications, which will be released shortly.Part 2 Coming Soon!: Learn about CCT / BIZ Contracts, Conceptual Models, and more!Stay tuned for Part 2 of the T-Bridge Framework Tech Explainer series, where we will discuss in more detail the CCT and BIZ Contracts, which power the T-Bridge framework and the conceptual models which guide the design of the framework.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain Founder Jack Lu — ...

Wanchain Founder Jack Lu — The 2019 Novel Coronavirus Epidemic & its Affect on the Blockchain Industry in ChinaAdapted from the original Mars Finance article (Original Chinese Version)In early 2020 China was unexpectedly hit with the 2019 Novel Coronavirus epidemic which not only threatens the lives and health of the people throughout the country, but also poses a huge challenge for economic development. The blockchain industry is not immune.In light of the epidemic, Mars Finance has launched a series articles — “Industry Watch: China’s Blockchain Industry in the Epidemic”, in which prominent figures from the industry directly address the current status of the industry in light of the epidemic.The following is shared by Jack Lu, edited by Mars Finance:The novel coronavirus epidemic situation is fierce and its contagiousness is startling. The government has urged all citizens stay at home as much as possible, avoid social gatherings, and work remotely. In areas where the epidemic is especially severe, the government has even adopted measures such as restricting travel in and out city and road closures.Although it is still vital for us to continue the development of Wanchain and its ecosystem in light of the epidemic, the health and safety of our colleagues is of course our top priority. Wanchain has actively responded to national guidelines for dealing with the epidemic, and at present, all team members are working remotely from home.We also require team members to make a daily health check-in and submit relevant information such as health status, body temperature, and contact with visitors from affected areas. Future measures will be based on the development of the epidemic situation and the government’s follow-up policies over the next few weeks.Telecommuting has improved the work efficiency of individual team members to a certain extent. For example, everyone does not have to spend time commuting every day. However, telecommuting harms coordination and collaboration within the team. Certain technical frameworks and products currently being developed by the team can only be successfully completed through the team’s in depth cooperation and collaboration. Obviously, face-to-face communication and discussion are more effective than remote conferences on the Internet. Fortunately, since the early days of Wanchain, it has had offices in the United States, China, Europe and other places, so we have accumulated a lot of experience in cross-regional and even multinational work collaboration.Companies (or organizations) in the blockchain industry can be roughly divided into four major categories according to their positioning and function: infrastructure, technology expansion, industry application, and media/community.The online and offline companies in the media/community category will be the companies who are most impacted by the epidemic. For example, companies related to offline blockchain exhibitions, offline courses, etc. may see a drastic drop in clients or even be restricted from operating by epidemic prevention policies. For media companies with a focus on online traffic, however, the epidemic may in fact lead to an increase in traffic.The epidemic impact on industry application companies will be very subtle. First of all, the spread of the epidemic, travel restrictions, and the temporary closure of many physical offices will inevitably reduce the number of business opportunities for application projects, which will lead to a decline in the revenue of industry application enterprises. However, at the same time, the use of blockchain technology to solve issues related to medical big data, charitable fundraising, drug traceability and other sub-sectors will see many new opportunities. Therefore, if industry application companies in these areas play their cards right now, they may see it pay off later in the year.For infrastructure companies and technology expansion companies, because there is little direct contact with offline clients, the impact of the epidemic is relatively small. For Wanchain, which focuses on the development of cross-chain mechanisms and is an infrastructure organization, the epidemic will affect us to some degree, but this impact is controllable and predictable and will not cause serious harm to the development of the project.Of course, new opportunities have also been created because of the epidemic, which can be considered from two dimensions:First is the strong demand directly generated by the impact of the epidemic, which is the use of blockchain technology mentioned above to solve the needs of medical big data, charitable fundraising, and drug traceability.These and related use cases will see great development this year. While there will be great opportunities in these areas, they will also be accompanied by huge risks. The demand spurred by the epidemic situation may be temporary, and the opportunities may fall as rapidly as they rise. A rapid decline does not represent the impracticality of blockchain-based medical big data sharing and charity donation on-chain projects, but just that these projects must be sustainable for a long time in the future. The current epidemic situation may generate a deceptively large amount of demand, and when the epidemic passes, this demand will disappear. This could have an adverse effect on companies that have invested heavily in these areas.The second is the industries that have been hit hard by the impact of the epidemic such as the catering, restaurant, tourism, and entertainment industries. The epidemic has brought demand in many of these industries to crash down. However, in the future once the epidemic has passed we can expect a strong rebound in demand. Blockchain services related to these industries such as food traceability, travel insurance, and copyright protection will also see rapid growth. Therefore, blockchain applications in these industries are worthy of attention.In addition to the industry divisions I mentioned above (infrastructure, technology expansion, industry application), the blockchain world can also be divided from another point of view: public chain communities, cryptocurrency communities, and the mining community. Well, emergencies like war and epidemic have different effects on companies on these different communities.The historical background of the birth of Bitcoin was the subprime mortgage crisis in the United States, which seriously damaged the credibility of the US dollar. Therefore, in the past ten years, Bitcoin has been regarded as one of the ways of capital preservation and hedging against the dollar. Leaving aside morality, emergencies such as wars often make various cryptocurrencies such as Bitcoin increase in popularity. Therefore, when global black swan events occur, not all black swan events will necessarily have a negative impact on cryptocurrencies.Regarding the mining community, this year will see continuing cryptocurrency production based on PoW consensus, such as BTC, BCH, and BSV. Unlike the black swan events mentioned above, the halving of production is certain, so what the mining community should guard against are gray rhino events. Historically, each halving always ushered in a round of new profits. Actually each round of new profits was based on some developments which brought new value, such as the emergence of smart contracts with Ethereum. However, if the current halving is not also marked by some major steps forward in the industry, it is likely that a gray rhino event will occur in the mining community, which may have a significant impact on the enterprises involved with mining.If the blockchain industry is to really make progress then it must return its focus to the development of the underlying technology since current blockchain technology is still in the very early stages. The issues of scaling, block storage, cross chain transactions, and security all require the unrelenting efforts of industry developers and experts for real progress to be made. It is only when blockchain technology is mature and robust that the large-scale commercial use of the blockchain will become a reality.In summation, external adverse factors such as war and epidemic will inevitably drag down the R & D process of the team driven by blockchain technology, which is obviously not good for the chain circle and the healthy development of the entire industry.— Jack Lu, Wanchain Founder and CEOAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain 4.0 Has Landed! Th...

Wanchain 4.0 introduces the new T-Bridge framework to connect private and public chains4.0 introduces the T-Bridge framework, a generalized framework for private-public blockchain asset and data bridgesWanchain 4.0 is now live on the Wanchain mainnet! View the smart contract code here. This release marks the accomplishment of one of the major goals of the Wanchain project as stated in the whitepaper released by the Wanchain Foundation— the integration with private blockchains.The 4.0 release features the T-Bridge framework (with the “T” standing for “Trust”), a generalized framework for data and asset transfer between heterogeneous public and private blockchains.The availability of this generalized framework will allow developers to connect their private chain-based applications to the world of public blockchains.The T-Bridge framework will also bring additional functionality (see below) to the cross-chain connections that are currently live on Wanchain, and will greatly speed up the integration of new cross-chain integrations. You can read up on the technical details of the T-Bridge (Universal Cross-Chain Framework) here.Wanchain’s Journey Building Cross-chain TechnologiesA major mission of Wanchain is to tackle the interchain interoperability challenges imposed by the rapid growth of private and public blockchains, particularly heterogeneous blockchains (blockchains that do not share similar technical architectures). July 2018, Wanchain 2.0 achieved its first cross-chain interoperability milestone by connecting Ethereum with Wanchain and enabling the transfer of assets between the two most significant public blockchains. In Dec 2018, Wanchain 3.0 achieved cross-chain interoperability between Bitcoin and Wanchain by allowing the two chains to transfer assets. Wanchain also brought cross-chain support for Ethereum’s ERC20 tokens, allowing for them to be transferred to and from Wanchain. Throughout 2019 Wanchain continued to expand its public to public blockchain bridges to bring support to more ERC20 tokens, EOS, and EOS based tokens.Wanchain 4.0 is focused on supporting cross-chain interoperability between private and public blockchains. Connecting private blockchains with public blockchains is typically more challenging for a number of reasons:Public blockchains are permissionless while private blockchains are permissioned. The consensus mechanisms of public blockchains are typically different from those used for private blockchains.Private blockchains have strict requirements for privacy and security. The bridges that connect a private blockchain with a public blockchain will need to have different security zones.Private blockchains are normally built and maintained by enterprises and consortiums. They are highly customizable, with each major private blockchain having multiple different flavors and configurations. While there are a generally recognized handful of major public blockchains, the number of private blockchains and their technical configurations are effectively unlimited.In order to tackle the challenges posed by the problem of private to public cross-chain interoperability, Wanchain 4.0 introduces the T-Bridge framework, a generalized framework and reference architecture with modular components and common protocols. This framework is compatible with Wanchain’s original Storeman cross-chain mechanism currently used for the public to public blockchain connections.Wanchain 4.0 leverages the T-Bridge framework to link components in source chains, target chains, and routing chains together and defines common components and protocols for cross-chain transactions. The framework allows actors such as end-users, CLIs, or API tools to access service providers to initiate cross-chain transactions. The cross-chain transactions are processed by the business service as well as the cross-chain smart contract and then transported to the protocol mediator (PM) for cross-chain operation. The processing and transport of cross-chain transactions are based on three models: the trust model ensures the integrity of the assets and data; interaction model to define blockchain specific smart contracts actions; and routing model to define cross-chain events, messages, and data transport. With the T-Bridge framework, a partner can write their own business and cross-chain smart contract and easily build decentralized cross-chain applications.The innovation of Wanchain 4.0 T-Bridge FrameworkIt provides an extension of Wanchain’s cross-chain solution of storeman nodes. With Wanchain 4.0 T-Bridge framework, more kinds of mechanisms of MPC algorithm can be supported, which include signatures of a single authority, MPC, schnorr, and proof of data for potential challenges in the future.It provides a reference architecture and platform for general cross-chain solutions. With Wanchain 4.0 platform, state machine based modes have been introduced for different cross-chain scenarios, thus developers or customers could easily define business-related contracts and configure the state machine with fewer development efforts. In summary, they can bring their cross-chain business quickly to market with the support of the Wanchain 4.0 platform.Significance of Wanchain 4.0’s T-Bridge Framework1) Connecting private blockchains allows for complex business scenariosThe framework allows for private blockchains to connect to other private or public blockchains using a router chain. This allows for a variety of complex business scenarios:Scenario 1: The issuance of frequent flyer miles on Airline Company A’s private chain which is then connected through a router chain (Wanchain for example) to an e-commerce platform’s private loyalty points chain. Through this connection, frequent flyer miles can be exchanged for customer loyalty points which can be used for purchase on the e-commerce platform.Scenario 2: A private chain used by an insurance company to register the validity of insurance claims. Using the T-Bridge framework, the insurance company may connect its own permissioned chain to a public router chain (i.e. Wanchain). Once a claim has been verified as valid and the corresponding transaction has been published on the insurance company’s private chain, automatic payment can be triggered on the public chain through the cross-chain connection.Scenario 3: A local government uses a private blockchain to record property ownership records. A local lending business uses a private blockchain to issue loans to individuals based on the property they are able to offer as collateral. Through a router chain that implements the T-Bridge framework (Wanchain), these two private blockchains can seamlessly connect, which allows for the construction of a loan product to offer users instant credit based on their property ownership.2) Connecting private chains allows for the establishment of global asset exchangeThe ability to connect with private chains is particularly important as private/permissioned chains are where the majority of legitimate tokenized assets will live in the future. Permissioned chains are necessary for assets that must comply with the laws and regulations of multiple jurisdictions and are subject to the control of a variety of regulatory bodies. By connecting together different private chains, Wanchain 4.0 paves the way for the establishment of global, compliant, blockchain-based asset exchange for traditional assets such as stocks, bonds, securities, and many more.3) Increasing utilization of locked WAN in Wanchain’s Storeman node architectureAlthough the role of Protocol Mediator and Router Chain may be implemented in a variety of different ways, using Wanchain as the Router Chain and Wanchain’s Storeman node architecture as the PM will be the best option for most users since it gives applications and services accessible to all the other private and public chains connected to the Wanchain hub. This will entail an expansion of Wanchain’s current Storeman node network. With each new private or public chain to be connected, a new Storeman group will be established, and more WAN will be locked up as a security deposit for each new Storeman group.4) Rapid expansion of the Wanchain Cross-chain networkSince the T-Bridge framework standardizes many elements of the cross-chain connection process, it will increase the speed at which blockchains can be connected with the Wanchain blockchain. To date, three blockchains (Bitcoin, Ethereum, and EOS), have been connected with Wanchain. With the launch of the framework on Wanchain 4.0, the rate at which new chains are connected to Wanchain is expected to speed up significantly.5) Cross-chain contractsSince the T-Bridge framework allows for generalized cross-chain transactions for BOTH assets and data, it opens up the possibility for cross-chain smart contracts. This means that a smart contract on Ethereum could, for example, listen for an event which happens on the Bitcoin blockchain through the router chain (Wanchain), and then respond to that event with a transaction. This allows for the construction of truly dynamic and complex cross-chain contracts.Request for partnershipWith the release of the generalized framework for cross-chain transactions, it is feasible for enterprises and consortia to connect their private blockchains to Wanchain or other public blockchains. We look forward to working with partners to extend this technology to bridge blockchains that are otherwise isolated.About WanchainWanchain is the infrastructure connecting the decentralized financial world.
