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. Band Protocol is backed by a strong network of stakeholders including Sequoia Capital, one of the top venture capital firms in the world, and the leading cryptocurrency exchange, Binance.Website | Whitepaper | Telegram | Medium | Twitter | Reddit | GithubAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

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. The first products FinNexus plans on releasing will be innovative tokenized assets (available Q1 2020) with value based on real world cash flows.Website | Newsletter | Whitepaper | Telegram | Twitter | Linkedin | FacebookAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

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.

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. You can stake or unstake NET and buy or sell RAM.Resource Management PageResource Management PageResource Management PageThe account creation page allows for the creation of new EOS accounts. These accounts may be used in the Wanchain wallet, or exported to other EOS wallets.Account CreationOn the transaction page you are able to send EOS from your selected account to the specified recipient account along with an optional memo field.EOS Transaction PageOn the import account page you are able to import additional EOS accounts.Import Account PageWanWallet is Now a Full Featured ERC20 Wallet!In the settings interface, users can enable (or hide) WRC20 and ERC20 tokens to display them on the wallet homepage.Add ANY ERC20 token to the WanWallet!Network DiagnosticsThe new ‘Network’ tab insides the settings menu allows for easy network diagnostics so users can understand more about the status of the iWan RPC server and the networks it connects with.EOS Cross Chain TransactionsThe new version of the Wanchain desktop light wallet supports cross-chain transfers of multiple currencies, including BTC, ETH, and now EOS, as well as ERC20 and EOS based tokens.Steps for making a cross chain EOS transaction:Making EOS cross chain transactions is easy, and follows the exact same process as ETH and BTC cross chain transactions:Select the Storeman addressInput recipient addressInput number of EOS to be converted to WEOSSend transaction!After a successful cross chain transaction you can view your WEOS in the menu on the left.EOS is just the first of many future cross chain integrations in the works for Wanchain! We are looking forward to at least two new major public chain integrations in 2020 along with several batches of new ERC20 and EOS based tokens.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

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.

The Storeman Group is composed of multiple groups of Storeman Agents and their MPC node. Storeman Agents monitor and sync data on the blockchain, and generates pieces of signatures with cross-chained data using their MPC node. MPC nodes interact with each other over a P2P network, reaching signature consensus, and eventually generate a signature, which includes smart contract transactions and cross-chain data, and then add data to the blockchain, completing the cross-chain transaction. The current signature algorithm used by Wanchain’s cross-chain mechanism is ECDSA, but since the signature algorithm of varies from blockchain to blockchain, this mechanism requires MPC nodes to support both signature algorithms of Wanchain and the cross-chained blockchain.Cross-chain with EOS introduces a Layer 2 signature mechanism, using Schnorr multi-party signatures. The Layer 2 signature mechanism moves the multi-party signature verification process on the blockchain, using smart contracts to perform multi-party verification. The MPC nodes only need to sign the cross-chain data using the Schnorr signature algorithm, then any Storeman Agent can pack this signature into data of a smart contract transaction, sign it and broadcast it to the blockchain. HTLC (Hash Time Locked Contracts) will verify the Layer 2 signature within the smart contract by verifying the smart contract with the Schnorr signature algorithm, thus accomplishing cross-chain data verificationCompared to ECDSA, the Schnorr signature algorithm is more efficient in terms of both computation and network interaction. It also gives more flexibility by extending the range of values of the multi-party signature’s threshold. The Layer 2 signature mechanism allows reaching consensus using only signature data, without need of support for various signature algorithms of different blockchains, thus drastically improved the versatility of Multi-Party Computation.2) Modularization of MPC, providing a solution for multi-party signaturesCurrent MPC nodes need to support various signature algorithms of different blockchains that are being cross-chained. With support of Schnorr signatures by Bitcoin Cash, and Bitcoin being expected to support Schnorr signatures in the near future too, it will be adopted by more and more blockchains. Using Schnorr as a signature algorithm of MPC nodes will greatly improve its versatility. With the modularization of cross-chain MPC nodes, and active authorization of data signatures for individual Storeman Agents, a multi-party signature solution is built upon the Schnorr signature algorithm. Modularized MPC nodes support a cross-chain platform, it can also work seamlessly with other DAPPs that need multi-party signatures. Community members and developers can perform multi-party signatures with the MPC node, it can be paired with smart contracts on Wanchain which supports signature verification using Schnorr algorithms, and it also allows users to build their own smart contracts to perform consensus verification, thus fulfilling the need for multi-party signatures in Dapps.3) Generalized HTLC cross-chain mechanism, truly versatile cross-chain platform for all blockchainsComplying with the BIP-0044 standard, we can combine a blockchain’s Hex ID and account address, encode them and use the encoded data as a unique identifier of cross-chain smart contracts registered on Wanchain, thus allowing Wanchain to realize HTLC cross-chain integration with all blockchains. By separating the data access layer’s smart contracts from the business logic layer’s, the business logic layer becomes more upgradable, making the cross-chain platform more flexible and versatile, significantly reducing the development effort required for new cross-chain integrations in the future.4. Relieving the Storeman Group of its locked account role, further decentralizing the cross-chain mechanismWith the current cross-chain technology, cross-chained blockchains and Wanchain both have Storeman Group’s locked accounts, and cross-chained asset will be locked in these accounts. With the new iteration of cross-chain technology, the Storeman Group is only responsible for multi-party signatures of cross-chained data, cross-chained assets will be locked inside HTLC smart contracts, and smart contracts controls the funds using business logic, making cross-chained funds safer.EOS is just the first of many future cross chain integrations in the works for Wanchain! We are looking forward to at least two new major public chain integrations in 2020 along with several batches of new ERC20 and EOS based tokens.Stay tuned for the Mainnet release of the EOS cross chain integration very soon!A big thank you to the Wanchain community for your continued support and attention.About WanchainWanchain is the infrastructure connecting the decentralized financial world.

Wanchain strengthens the bl...

Since the inception of Bitcoin in 2009, blockchain technology has transformed tremendously. Bitcoin — as the most well-known cryptocurrency — has paved the way for decentralized P2P networks, smart contracts, DAGs, and practical enterprise use cases. Blockchain, as a whole, has allowed greater transparency, efficiency, and security. These are some of the critical factors for enterprises when evaluating new services and solutions.Nevertheless, there is one prominent area that needs more focus — blockchain interoperability. Blockchain interoperability means that different networks (blockchains) can freely share value and data. Currently, there are numerous blockchains, with the primary obstacle being this lack of external communication. At Wanchain, we have decided to focus on this particular interoperability problem; on how to bridge different networks together (public and private) and have them all communicate, operate, and interact under standardized rules and procedures.Diffusion of Innovation, SourceHow it all startedWanchain started in 2016 when Jack Lu formed a research team from Beijing University (Peking University). They started research into different interoperability technologies until they created a Proof of Concept (PoC), bridging Ethereum to another EVM-based chain. Wanchain was born shortly after, and the race to solve the interoperability problem began. Wanchain has achieved significant milestones since its inception. These are the 1.0 release (mainnet with privacy), 2.0 (bridging Ethereum), 3.0 (bridging Bitcoin), and soon, we will release the EOS integration and 4.0 (connecting private blockchains to our public platform). To better understand how interoperability works on a practical level, we will guide you through several use cases within different industries. From retail payments to tracking of luxury items to digital collectibles, blockchain interoperability is vital and is becoming a topic of focus, slowly but surely.The similarities to the Internet we know todayIn the early days of the internet, the participating networks could only transfer information (via messages) within these siloed intranet networks. It was not until the introduction of the Advanced Research Projects Agency Network (ARPANET) that systems started implementing TCP/IP protocol suites and allowing communication outside of these hubs. Most of us are unaware of how the internet truly works, and we don’t need to understand how it works either. We’re at a stage now with Blockchain technology that we — the pioneers, the first users, innovators, and marketers — need to come together to improve the user experience, educate the current and future generations, and build solutions to actual problems. All of these factors are vital to lower the barriers to entry and increase usage amongst regular individuals and entities.From KWDEX to WRDEXIn 2018, we released the first instance of our privacy-enabled smart contract platform, along with significant partners. At first, we discussed the release of a Kyber-Wanchain Dex (KWDEX) until both projects decided to focus on their roadmaps and delay development. Fast forward to the present day, and you have the WRDEX (Wanchain-Rivex DEX) coming out in a few months with cross-chain improvements, new integrations, enterprise partnerships, and research milestones in 2020.WRDEX is a massive achievement for Wanchain and its ecosystem. The WRDEX is being built with the same vision in mind as KWDEX, allowing you all to trade highly-liquid assets (such as ETH and BTC) in a decentralized and effective way. The DEX operators share the order book, choose which coins to list, how to provide liquidity, and run their marketing and community campaigns. With every individual being the owner of their wallet and assets, users make all the calls from their wallets. It’s no surprise that we’ve transitioned from largely centralized political economies to global decentralized digital economies, where power is transferred to us — the people.WRDEX 1.0We’ve identified several of the current and future enterprise interoperability use cases, and we want to guide you through them. These are some of the ones currently in development:FINANCEMoney is a medium of exchange and is accepted as a payment for goods and services, taxation obligations, and repayment of debt. This new digital economy operates under a deterministic set of rules thanks to the introduction of smart contracts. Smart contracts are self-executing code on the blockchain). The traditional financial world has been under attack for centuries, but the stakes are higher than ever. The economies before this technological shift did not allow for such radical change.Nonetheless, we are now forced into change because the “obligations of the state are being questioned.” In the past, theorists have questioned and discussed a variety of models. Still, it is only now that we are bringing those ideas into code — where we step away from probabilistic towards deterministic outcomes.Bonds, derivatives, and shares — These are examples of digital assets and financial securities that play a fundamental role in the finance industry. One can transfer these from Lanchains (Private chains on the Wanchain network) or other private networks to a public chain for trading, proof of ownership, or KYC. Wanchain’s interoperability functionalities will allow value to flow between off-chain platforms and on-chain platforms, which will open up the possibilities with blockchain technology. For instance, smart contracts bring algorithmic trust to P2P transactions, where parties can trust the code to be fully deterministic and executed when conditions in the agreement have been satisfied.Remittance — Remittance is a transfer of money by a foreign worker (typically someone working away from home) to a person in their home country (often a family member). Remittance has been one of the first and most evident disruptions of Blockchain technology, as you take away the middlemen, hefty fees, and the long waiting time to process payments. Interoperability would allow a foreign worker to send WBTC (Wrapped Bitcoin on the Wanchain blockchain) to a family member instantly, who would then be able to redeem the WBTC for the native Bitcoin. The network and the respective assets are secured by what we call “Storeman Nodes.” Each new blockchain integration (ETH, BTC, EOS, etc.) requires a set of 21 nodes that are programmed to split and randomize the private key of a locked account. A closed account holds a certain amount of coins on their respective chains. As a result, no central custodian is holding your assets as the private key is distributed amongst the 21 different Storeman nodes and only 16 out of 21 need to be online again, to recreate the private key.SUPPLY CHAINA supply chain is a network that comprises all the individuals, enterprises, resources, and technologies involved to produce and distribute a product to an end buyer. There are numerous parties involved in a supply chain process, where you begin with natural resources and end with the customer. Payments, auditing, communications, and quality control are just a few of the procedures involved in this chain and industry. Subsequently, there are different systems throughout this entire process. Today, these systems experience inefficiencies due to not being fully bridged together, and this is where interoperability (through Wanchain) will allow two or more systems to transfer value and data.Luxury Goods — Nowadays, we have blockchains focusing on different markets, where the supply chain is crucial. For instance, Vechain has been collaborating with many institutions for the tracking of luxury items (from production to final delivery). LVMH has opened up a Blockchain division for supporting the growth of its white-label blockchain, hoping their competitors end up using these services. However, the trend has been towards these companies creating their blockchains or working directly with a public platform. Interoperability will become the most critical component in the supply chain as all these independent and siloed blockchains will have no other way to communicate with the external world.Tracking of goods across a global network — How can a producer in India seamlessly transfer value or data across to a supplier in Denmark? With a standardized “communication” protocol, this is possible. With the implementation of cross-chain NFTs (ERC-721, etc.), tracking devices (RFIDs), and cross-blockchain communication technology, we can create fully interoperable chains regardless of the base layer. Supply chain leveraging blockchain is genuinely changing the overall landscape as we know, including industries such as automotive, vaccines, agriculture, and natural resources.IDENTITYDecentralization is an important aspect that’s only feasible through blockchain or DLT. Identity is a core part of this. Usually, governments are the ones that are issuing the identity of their respective inhabitants. However, national ID cards, driver licenses, and passports replaced by new digital identities. Digital IDs have started to be issued by countries like in the case of Estonia. These identities can be stored on a distributed ledger, resulting in a tamper-proof, decentralized, and fully transparent identity that is available for everyone — with certain limitations, of course. A new digital identity means that one will be able to verify their identity and personal information without revealing any confidential information. As the technologies and services progress, we will see the entire space open up for communication and data flow between components that require some form of KYC/AML verification.Evernym (namely Sovrin) has been working on DIDs for years now. DID (decentralized identifier) is a new type of globally unique identifier that does not require a centralized registration authority (like in the case of ICANN for domain names or NANP in the United States for phone numbers). With standardizations and implementations of these identifiers across different blockchains and systems, a fully interoperable global network becomes a lot more apparent. IP addresses allow different devices to connect while DIDs enable people to connect. The work being done through W3 and similar organizations will enable DIDs to fully interact regardless of what blockchain they are on. This would be one of the most significant advancements since the release of the URL and is an important market for Wanchain to penetrate. Please read about our recent partnership with Evernym here.Voting — Elections are structured and enforced differently in various parts of the world, which is why creating solutions surrounding voting is an essential part of blockchain technology. Here all components and parts of the voting process must communicate with each other, allowing the transfer of data. Interoperability needs to be incorporated to facilitate secure and effective elections, where the entire process can happen in a decentralized manner. No authority, regardless of their ideologies and values, will have the opportunity to tamper with the ballots.Intellectual Property — Intellectual Property (IP) is the creations of the mind like inventions, designs, names/images, literary and artistic work. These IPs might be registered differently between jurisdictions. A public blockchain provides the freedom to check IP databases to verify the rightful owner. All this is established through a structured system with timestamps and other verification methods; society will be able to recognize an individual’s ownership to IPs in a lawful manner.MEDICALToday, cities often have different hospitals and clinics with distinct medical record data systems. It’s challenging to attain fast and reliable access to medical data in case a particular patient goes to different hospitals since these systems are not interoperable. This means in reality that you can get treatment at one hospital, but other hospitals or medical centers will not know about this visit. Even if each hospital starts using a different blockchain to assure security, transparency, and immutability, they would still need to communicate externally. Subsequently, this puts increased risk and inefficiencies regarding how the system is currently structured. Wanchain’s interoperability protocol would allow two hospitals (or more) with different blockchains, to communicate with one another.Medical records — One of the most available and suitable applications for blockchain is patient data management. Due to the structure of the entire medical industry, it’s impossible to build up a complete profile with the patient’s medical history, since care providers and health agencies tend to be separated. This separation results in human error and time-consuming processes, leading to severe structural inefficiencies. All the information will be securely transferred between various parts with blockchain to provide information in a smooth and accessible manner.Track pharmaceuticals and clinical trials — Hundreds of thousands of people die every year due to counterfeit drugs, e.g., treatment for malaria and pneumonia, children medication, opioids and more. These products do not contain the active ingredient listed on the medication box. The packaging is almost identical to the legitimate pharmaceutical drugs, but they replace the active ingredient with a cheaper, more dangerous alternative. They are usually purchased because their prices are a lot lower than the market price. This situation is mostly taking place in developing countries, but it has also happened in more developed ones like China, who experienced a nationwide vaccine scandal.The pharmaceutical companies must be working within the guidelines of their respective governments. With interoperability, it will be more convenient to track the state, information, and other essential data throughout the entire medical chain. Interoperability will provide greater availability to check if the medicine has changed or alternated — and also the whole lifecycle of their medication — respectively.Are companies using Blockchain?Yes! They are. 2017 was the year of the ICO, the altcoin market boom. Project “value” rose too quickly, and companies were deterred from getting involved with these projects because there was too much noise. 2018 was the #buidl year; the start of #defi on Ethereum and 2019 was the year that companies started to be public about their Blockchain involvement: announcing pilots, releasing PoCs, and announcements regarding collaboration with private and public chains.Hype Cycle, SourceSo how does all of this relate to Wanchain? Well, in many ways. Let’s take one step back and explain the main differences between private and public blockchains. For starters, Wanchain is an open platform, which means that anyone is free to use the platform. There is no limitation to who and how you send and receive value. If someone wants to create a decentralized marketplace using WBTC, WETH, and WAN, they can do so without the support from the Wanchain Foundation. Anyone can issue dApps and tools that can be further improved by the community of developers.When you look at economics, a public good is a commodity or service that is provided to a particular society without profit. This is done by the government, private individual, or institution. A public chain is offered to the community without profit. Excess value is distributed across a network of miners (e.g., Proof of Work) or validators (e.g., Proof of Stake). You give up electricity, “a stake in the network,” or computing power in return for this token or asset of value.A private chain, however, is a permissioned network that places restrictions on the participants. There is absolute control over who can write data to the blockchain. Both types of blockchains are necessary. Public chains are distributed (a scattered network of miners or validators secure the network), immutable (transactions cannot be reverted — although in some cases through governance, you can), and transactions can easily be verified by anyone (thanks to block explorers). Private chains can choose their consensus and can easily change the state, economic conditions, and permissions for users. Transactions are faster (fewer nodes needed) and can be adapted depending on compliance requirements (e.g., GDPR compliant). There is a tendency towards believing that private and public chains are competitors when they are compatible.Lanchains and Wanchains — Bridging the traditional financial world to the new digital economyWanchain has two development arms, one for its proof of stake-consensus public chain and one for private chains. Although resources are put mainly towards the development of the Wanchain public chain, we do have a dedicated team of developers that provide PoCs and develop Lanchains for enterprises. As Adam Ludwin, CEO of Chain, puts it: “Over time there will be more of a convergence of what’s happening in the enterprise and what’s happening on the open Internet to create this future of value over IP.” The blockchain space requires standardization when it comes to intra and extra-communication (flow of data & value within and outside of the ecosystem).To better understand why private and public chains are needed, you can look at the internet. Companies connect to the public domains on the internet but still use private networks for storing files and using it as a medium of communication between employees. Companies that need to share information with partners, governments, regulators, or any other third parties will need to connect to the outside world. Various interoperability standards are being proposed, but the only tested and secure, scalable solution is a combination of atomic swap technology and secure multiparty computation (sMPC). You need wider-community acceptance before distributing such technology to the masses. There needs to trust in the technology before there is a trustless bridge. Wanchain is working on several initiatives outside of its ecosystem to gain brand awareness and, ultimately, a comprehensive understanding of its technologies and services by enterprises in different industries. Weijia Zhang, VP of Engineering, is working closely with the Enterprise Ethereum Alliance on interoperability standards, and we are joining forces with several top consortia in the space to help set these standards.We will continue to work on enterprise and public chain use cases and provide our community with consistent updates on what we’re working on, what it all implies, and how all our technologies and partners work in synergy.Expect a lot more news as we continue to bridge the traditional financial world to the new digital economy.About WanchainWanchain is a blockchain platform that enables the decentralized transfer of value between blockchains.

Mercury hard fork hits the ...

Validators — update your clients before the dateThe hard fork upgrade named Mercury is scheduled to occur on December 20 2019 at 0:00 AM UTC on the Wanchain mainnet. When the Epoch ID of Galaxy Consensus reaches 18250, all Wanchain GWAN clients on the mainnet which have been updated prior to that date will smoothly switch to the new Mercury branch.In order to ensure normal syncing process after the hard fork, all validators and all users running GWAN on Wanchain mainnet must update their GWAN clients to the latest version before December 20 2019 0:00 AM UTC.How to update the GWAN client:For updating of your GWAN client, you can choose between an update using scripts or amanual update.1) Update mainnet GWAN using scripts:We have prepared easy to use scripts for updating theGWAN client. Users who have deployed GWAN using scripts can log into their server through SSH protocol then execute following instrcuctions:$ rm updateMainnetValidator.sh$ wget https://raw.githubusercontent.com/wanchain/go-wanchain/develop/loadScript/updateMainnetValidator.sh && chmod +x updateMainnetValidator.sh && ./updateMainnetValidator.sh(Further details about Wanchain PoS scripts can be found here)2) Manually update mainnet GWAN:In a customized operating environment, users can manually download GWAN binary version 2.1.4 through the link below and update the GWAN client by replacing the current one with the newer version:https://github.com/wanchain/go-wanchain/releases/What’s new in the Mercury upgrade?The Mercury upgrade will bring two long awaited important features/feature upgrades:1) Smart Contract API for Safe Random Numbers2) Raising blocks’ standard gas limitThese 2 new features/upgrades are essential for promoting Wanchain’s ecosystem, increasing Wanchain’s developer friendliness, and promoting new development path of DAPPs. They are detailed in the following:1) Smart Contract API for Safe Random NumbersOne of key innovation in Wanchain’s Galaxy Consensus is Safe Multi-Party Random Number Generation. It periodically generates a group of random numbers on the blockchain through Galaxy Consensus Protocol. This random number is a true random number that is unbiased, unpredictable, and evenly distributed within its range.Safe Random Numbers lay the foundation for all blockchain based gaming DAPPs. A truly unpredictable, unbiased (cannot be manipulated by anyone, even miners) random number serves as a safeguard for gaming DAPPs, it can guarantee the fairness and trustworthiness of a game, preventing insider trading and all kinds of hacking attempts.By opening an API for Smart Contract deployed on the blockchain, DAPPs can be operated in a fully decentralized way. It takes only a front-end web page plus a Smart Contract on Wanchain to build a fully functional gaming DAPP.Prior to implementation of a true random number, gaming DAPPs mostly rely on block hashes, transaction hashes, or external oracles as sources of randomness. Block hashes and transaction hashes are vulnerable to manipulation by miners and stakeholders, external oracles on the other hand, tend to rely on availability and trustworthiness of a centralized source of randomness. Neither of them can provide both fairness and reliability in a decentralized way, they can merely raise barriers to wrongdoing.The API for Safe Random Numbers introduced by Wanchain’s Mercury upgrade can provide a source of decentralized true random numbers which can’t be manipulated by miners or individuals. Additionally a Smart Contract API can drastically simplify the amount of development effort and server costs required to provide randomness.It empowers fully decentralized, serverless DAPPs and makes them a reality — the key take-away of this new API.2) Raising blocks’ standard gas limitWith the Mercury upgrade, blocks’ default gas limit have been increased from 4.7M to 10M on Wanchain.This increase greatly improves the development experience of large scale DAPPs on Wanchain and removes the constant need to break down smart contracts in order to fit them on the block due to a low gas limit.Smart contracts written in Solidity on other blockchain platforms can now be migrated to Wanchain with greater ease, allowing developers to focus more on Wanchain and leverage its unique features, bringing more DAPPs of higher quality to Wanchain.This upgrade also raises Wanchain’s instantaneous TPS, paving a quick path of data for future DeFi DAPPs to take, improving the efficiency of transactions.Therefore, the higher gas limit included in Wanchain’s Mercury upgrade will bring benefits for all sorts of applications.If the Mercury upgrade and hard fork on Wanchain’s testnet goes smoothly, Wanchain’s mainnet will also undergo this upgrade in the coming days.So, to all validators and all parties running the GWAN node: please pay attention to Wanchain’s future announcements.Thanks for your support for Wanchain and its decentralized cross-chain mechanism, looking forward to a bright future for blockchain and open finance!About WanchainWanchain is a blockchain platform that enables decentralized transfer of value between blockchains.

Wanchain Roadmap 2020

2019 — Galaxy Consensus Was Born2019 was a pivotal year for Wanchain, most notably our consensus mechanism was upgraded from permissioned proof of work (PPOW) to proof of stake (POS) using Galaxy PoS Consensus. The new POS consensus mechanism developed by Wanchain’s own research team and draws from the research done by IOHK for Cardano with the Ouroboros proof of stake algorithm.The upgrade was a smashing success, as the numbers clearly spell out. As of today, three months since the launch of Galaxy on the mainnet there are:20% of total circulating WAN currently locked in Galaxy PoS~23 million locked WAN in Galaxy PoS~2000 delegators57 validator nodes (47 delegation receiving, 10 non-delegation)In addition to the work on the consensus mechanism itself, the Wanchain team also released a number of new updates including an all new light desktop wallet with support for staking and delegation, a mobile wallet with delegation support, updates to the old full node desktop wallet, additional language support, an all new website, additional ERC-20 integrations, and developer tools for validators.Wanchain’s 2020 RoadmapWanchain’s 2020 RoadmapFocus on ApplicationsWhile 2019 was all about Galaxy Consensus, in 2020 we are making a major pivot to focus on making Wanchain a better choice for dApp developers. This will be done both through additional tools which make the Wanchain dApp building process easier than ever, as well as upgrades to GWAN, the Wanchain core protocol client.dApp Development ToolsWanchain Explorer overhaul for DApp developmentThe overhaul aims to improve support for smart contracts on the explorer. Any user can verify the consistency between the smart contract’s source code and its copy on the blockchain with new version of the Wanchain Explorer.DApp Integration FrameworkThe framework will allow developers to integrate their DAPPs easily with the Wanchain Wallet, giving them full access to cross-chain and private transaction features of the official wallet so they don’t need to build these features themselves. This allows DAPP developers to focus on their DAPP’s business logic and not have to worry about the details of cross chain and private transactions.Release of Wanchain DAPP development toolkitWanchain’s DApp development toolkit will provide developer facing tools to facilitate building, testing, and deployment of DAPPs on Wanchain, starting with the iWAN SDK that is already available to all community developers.Random number generation service This service will provide DAPP developers with a high quality and high frequency source of randomness for use in their DAPPs. Random numbers are essential for the development of a large variety of applications such as games, gambling DAPPs, generation of secure passwords, and much more. A verifiable random number generation service is an invaluable tool in any DAPP developer’s toolkit.Core GWAN Protocol UpgradesProof of Concept of WASM on WanchainWASM on Wanchain will allow Smart Contract to be developed with C++, C#, JS, Rust, etc. It will also improve drastically the efficiency and performance of DAPPs on Wanchain.More Cross ChainIn addition to the increased focused on applications, 2020 will also see a major expansion of Wanchain’s cross chain integrations. In addition to new ERC-20 and EOS tokens, at least two new public chains will be integrated.Additional Cross Chain IntegrationsIntegration of at least two new mainstream public chainsNext 4 sets of ERC-20/EOS token integrationsIncrease Storeman DecentralizationOpen Storeman Initiative (3 phases)This multi-phase initiative will gradually open up participation in Wanchain’s cross chain Storeman node system to the public, and will eventually lead to the total decentralization of the Storeman system. The initiative will begin by opening a number of nodes to the public, and will become progressively more open to the community going forward. Participating node operators will be incentivized to operate Storeman nodes similarly to how current PoS node operators are incentivized.Research and Proof of ConceptsStandards based cross-chain mechanism & infrastructureWanchain has integrated with and will continue to integrate with blockchains with different characteristics like Bitcoin, Ethereum, EOS and also enterprise blockchains, using its cross-chain mechanism. We aim to provide a practical standard and necessary infrastructure for the blockchain industry that anyone can follow and use to build their own heterogeneous cross-chain implementation, not limited to those built with the same SDK.Proof of Concept of cross-chain integration with Libra, DCEPWith the potential future introduction of various kinds of stablecoins to the market that are backed by either strong industrial or national support, Wanchain as one of the leaders in the cross-chain domain intends to follow up closely the evolution in the stablecoin field and propose solutions to bridge them.Proof of Concept of cross-chain mechanism for NFT (non fungible tokens)NFT tokens have gained the attention for their ability to represent and map real world unique items like land titles, contracts, art collections, etc. into blockchain world. A cross-chain mechanism however is still missing for NFTs, and Wanchain plans to fill this gap by developing a cross-chain mechanism for NFTs. An obvious difficulty which could occur is providing a dynamically adjustable collateral mechanism for cross-chain NFTs.A big thank you to the Wanchain community for your continued attention and support! 2020 is shaping up to be a big year for us and the greater blockchain industry.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.
