Completing TasksStoreman Node TestingBefore the launch of Wanchain 5.0 Mainnnet, we will have three complete MPC group testing cycles open to the public. Each cycle starts with forming a Storeman Group and ends with ungrouping the Storeman Group. For every cycle, if a Storeman node is selected into the group and stays online will be rewarded with 300 WAN. If twice selected, the node will be rewarded with 600 WAN, and if selected three times, will be rewarded with 900 WAN.Storeman nodes which are not selected into the Storeman Group will be entered into a lucky draw. 30 lucky Storman nodes will be rewarded with 100 WAN each.Delegation TestingUsers who successfully delegate WAN to a Storeman node using the official Wanchain Desktop Wallet will be entered into a luck draw. 30 lucky delegators will be rewarded with 100 WAN each.Cross-chain Asset Transfer TestingUsers who successfully make a cross-chain transaction with WAN, ETH, EOS, BTC, FNX, or LINK using official Wanchain Desktop Wallet will be entered into a luck draw 30 lucky delegators will be rewarded with 100 WAN each.Lucky draw rules:We will get a random number from Galaxy Consensus on chain on the exact day when Wanchain 5.0 Mainnet launches. This random number will be used in turn to hash the records in the tables of the unselected Storeman nodes, the delegators and the cross-chain transfer users. The top 30 addresses with bigger hashed value for each role will be rewarded with 100 WAN per address.[WZ: The hash functions will be transparent and verifiable to ensure fairness in the selection process.]2.

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.

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.!!!!!!!!!!!!!!!

(See Section 5 for how to generate Keystore and Nodekey)5.3 Install Storeman ServiceInitialize the environmentOpen PortLog in Storeman management platform. 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 run your own node, please add a corresponding port)Initialize the environmentsudo chown "$USER" ~/osmcd ~/osmwget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/init_open_storeman_Env.sh && chmod +x init_open_storeman_Env.sh && ./init_open_storeman_Env.shwget https://raw.githubusercontent.com/wanchain/two-way-bridge-contracts/master/helpscript/startStoreman.sh && chmod +x startStoreman.shGet host ip as mongo ip through ifconfigAccording to the picture above, host docker ip is 172.17.0.1Please manually create the password file of workAddress.

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. If you have your own idea you can apply for a bounty for it here: https://forms.gle/ghgPMuEyv1foRAGu8. — Noah & JackAbout WanchainWanchain is the infrastructure connecting the decentralized financial world.

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.

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.

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 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.

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.

Wanchain New Wanchain GWAN ...

On April 29th, Wanchain (Wanchain) main network released a new version of the GWAN client (V2.1.5). Compared with the previous version, the biggest change in this version is the reduction of of gas fees for transactions from the original 180Gwin to 1Gwin, making gas fees on Wanchain negligible. This makes DApp usage much cheaper, making Wanchain more attractive as a platform for both DApp creators and users.WAN UnitsHow to UpgradeValidators must complete the upgrade before 00:00 UTC on May 4th, 2020, so as to avoid causing PoS transaction to fail and affecting own PoS revenue.Download GWAN (V2.1.5) hereMethod 1The update script runs as follows: ($ is the command prompt of the console, please do not copy)$ rm updateMainnetValidator.sh$ wget https://raw.githubusercontent.com/wanchain/go-wanchain/develop/loadScript/updateMainnetValidator.sh && chmod + x updateMainnetValidator.sh && ./updateMainnetValidator.sh(Other commonly used scripts)Method 2: Zero Downtime MethodSince shutting down the node during upgrade may result in loss of revenue, the upgrade can also be done without stopping your node as follows:Keep the old node running and create a new cloud service nodeCopy (or create) the keystore file to the ~ / .wanchain / keystore / directory of the new nodeUse the update script to start the new node (The script is the same as Method 1)Wait for the new node to complete synchronizationStop old node between 7:00 and 8:00 AM Beijing timeAbout 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.

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.

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.

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.

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.

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. Wanchain’s live cross-blockchain solution is EVM-based, includes optional private transactions, and provides a decentralized, permissionless, and secure approach for interoperability.

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. The Wanchain infrastructure enables the creation of distributed financial applications for individuals and organizations.

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.
