Collecting ViteX Listing Re...

It has been a year since ViteX went live. Even though the year 2020 has been tough, we are excited to see ViteX, as a DEX, has come this far, and we are very thankful for the tremendous amount of support and compliments we received along the way from our users, and our operators such as VGATE, Bi23, and so on.ViteX has always been committed to support both new and established blockchains, especially less-known and undervalued altcoin projects, and help drive awareness in the industry. As ViteX is going into an expansion period, we wish to attract more new users through listing projects with high quality and valuable potential, and we’d love to hear your thoughts. Make recommendations of projects you wish to see on ViteX, you will have a chance to win a maximum of 10,000 VITE (~150 USD) if your project gets listed!Rewards Details“Scout” Reward: 5,000 VITE shared by up to two peopleWe will select a project from the recommendations that is most suitable for ViteX. Keep in mind that the hottest projects are not necessarily the best to be listed by us. The selected project will have a pool of 5,000 VITE to be shared by two (2) recommenders at the most. This will be the first person introducing the project, and the person providing the most comprehensive information on the project. It can be the same person!“Liaison” Reward: 5,000 VITE poolAn additional pool of 5,000 VITE will be rewarded to one or more recommenders that successfully lobby the target project to list on ViteX. This set of winners can be completely different from the winners above. Basically, anyone can be our representative, our business development agent, for that project. To be fair, we will not decide who to win this reward, but let the project officials decide. We will ask their opinions on whom to be rewarded at the time of listing.ExamplesScenario 1: Jane Smith discovered a great project called XYZ. She submits the coin recommendation Google form and then contacts the XYZ project team to list on ViteX. The project team agrees to list, and XYZ has been selected by Vite team as the *best* recommended project. Jane happens to be the only person recommending XYZ. So she gets 10,000 VITE.Scenario 2: In addition to scenario 1, Adam Johnson also submitted XYZ and provided extremely comprehensive explanation for why XYZ is a worthy coin. But he is not the first person to recommend the coin. Adam also contacted the XYZ project to list on ViteX, and XYZ project team informs ViteX that both Adam and Jane deserve the “Liaison” reward. So Jane and Adam share the “Scout” reward of 5,000 VITE, and the “Liaison” reward of 5,000 VITE>We will accept recommendations throughout July! Here’s the recommendation form.Selection CriteriaSize of communityScarcity of exchange listingsFrequency and recentness of Github commitsYou will be asked to provide the following information about the project:Name of ProjectCoin TypeTotal and Circulating SupplyCoin InflationCoin Distribution Breakdown (Market, private, team lockup, etc.)ICO or IEO — If yes, please provide details (ex, platform, ICO/IEO size, coins collected).Trading ExchangesSize of Community (if known)Active Social ChannelsEvidence of Active Software Development— Go to Github, select an active repository.— Go to Insights, select Pulse, and change the period to “1 month”— Record the following data:Excluding merges, * authors have pushed * commits to master and * commits to all branches.

Vite Roadmap: Review for Q2...

A Letter from Charles LiuDear Vite Community:I am writing about two things regarding our roadmap. First, I will review the milestones we achieved in Q2 2020, which I am very proud of. Second, I will communicate to you some adjustments we are making to the Q3 and Q4 portions of the roadmap. These changes are based on both results of the community survey and a focus on strengthening our flagship product — ViteX.Q2 ReviewLet me run through each item in the Q2 list of milestones.DeFi — Borrowing and Lending: This is discussed in detail in this article. I will only add that, while we are pivoting away from this product, we are focusing on products with much bigger bang for the buck, as you will see in the roadmap adjustments section below.Hardware Wallet — Ledger: Enabled. Command-line installation of wallet app is now available. Ledger app store installation pending approval by Ledger.ViteX in Mobile — Klines: Display of k-lines (aka “candlestick graphs”) has been added to our mobile version of ViteX.One-step DEX Deployment: An initial version of open-source gateway code has been completed. Third-party gateways may now be easily deployed: HD Wallet — BTC Support: Wallet app is currently undergoing restructuring prior to commencement of BTC support. We had sent a community survey that is related to the restructuring. (LINK)Vite Web Wallet Upgrade: The main upgrade is interoperability between web wallet and the hardware wallet Ledger.Vite Desktop Wallet: This was released: Open API: This was released: and Q4 RoadmapsSee below for the new Q3 roadmap, with explanation:Q3 2020 RoadmapBased on community survey results and internal review, we have decided to delay the release of “Smart contract — scheduling service” and “Vite Naming Service” due to a lack of perceived immediate use. They are no longer included in the 2020 roadmap.See below for the new Q4 roadmap, with explanation:Q4 2020 RoadmapWe are postponing “Vite 2.0 — Alpha Test” and “ViteX on Vite 2.0 — Alpha Test” to allow proper and thorough design for Vite 2.0, and to give room for multiple other new items on the roadmap.For the change to the item “DeFi on Vite 2.0 — Alpha Test,” see earlier discussion on DeFi.ConclusionAs I previously mentioned, I am pleased with our accomplishment in Q2, and I look forward to tackling these challenges as outlined in the new roadmap in the coming months. I am as excited about the future of Vite as ever, and I hope you are as well.If you have any questions, feel free to ask! We are reach-able on our various channels, including our regular AMAs.Regards,Charles LiuOfficial: Official: Forum: https://forum.vite.netTelegram:English: Roadmap: Review for Q2 and Adjustments for Q3/Q4 was originally published in Vite Labs on Medium, where people are continuing the conversation by highlighting and responding to this story.

The Survey Result for ViFi ...

Dear Vite Community,On June 17, we have sent out a survey about ViFi (DeFi on Vite) asking for your inputs, in terms of the actual demand for ViFi, and borrowing/loan rates acceptable under said demand.Here we would like to share the results with you.Use Cases SurveyThe demands mainly lie in borrowing and lending VITE and VX — 61% in TotalBorrowing VITE (and VX)Statistic shows a majority of participants will borrow VITE at a rate under 15%, who take 67.8% in total plus those with no need.Most people wish to borrow low, which is completely understandable.Lending VITE (and VX)In this chart, 62.7% of the participants want to lend with a yield above 15%.People want to lend high. This is reasonable too.Borrowing USDT and Lending USDTThe results are relatively scattered. But still, 67.8% will only borrow USDT at an interest no higher than 6%, while 57.6% of participants will only lend USDT at no less than 6%.Analysis and Our DecisionBased on the survey, we reached the following conclusions:The majority (67.8%) of participants would only borrow VITE/VX at a rate under 15%; in the meantime, the majority (62.7%) of participants will only lend VITE/VX to others with a yield above 15%. This means only a fraction of the total surveyed group would be able to find a match for their borrowing/lending needs.The total number of respondents was not low, but also not high. When combined with the above fact that only a fraction of respondents will participate, we conclude that usage would not be strong.Staking of VITE to obtain VX consistently yields 20%+, and this already satisfies the 70% of the lending demand according to the survey.We made similar conclusion for the cases of borrowing/lending USDT.Many other priorities await our attention, as you will see in our new roadmap.As such, we have decided to suspend ViFi’s development. To be sure, we can revisit this topic at a later time, when there’s strong evidence of more user demand. Vite is like a high-speed train, which sometimes needs to stop during the journey, to refuel, get more people on board, and head for the next stop. We will not stop the research and exploration of DeFi, but will restart the opinion gathering process on ViFi from the community at an appropriate time in the future.In the meantime, our resources are better directed at other efforts, including continual improvement of ViteX (such as integration with more coins on ViteX, open-source ViteX gateway) and Vite App (Major upgrades and third-party development on Vite wallet), as well as other items to be mentioned in our quarterly milestone review letter.Official: Official: Forum: https://forum.vite.netTelegram:English: Survey Result for ViFi (DeFi on Vite) and Our Decision on this Product was originally published in Vite Labs on Medium, where people are continuing the conversation by highlighting and responding to this story.

Binance Block 101 : Exclusi...

Binance Block 101 : Exclusive Talks with Charles Liu — The New Stories of Public Chain and DEXOn June 19, 2020, in a live AMA program hosted by Binance Block 101, Vite CEO Charles Liu shared with audience the new stories of public chain and DEX (Decentralized Exchange). the interview, Charles pointed out that in the blockchain space, people often overestimate the short-term benefits, but underestimate the long-term gains. He personally values projects with solid fundamentals and unique innovations.Charles shares that he established Vite when there was no mass adoptions for blockchain. He hopes that Vite can fill this gap and make blockchain “useful.” The mission of Vite is to provide a high-performance public chain for high-frequency, micro transactions at greatly reduced costs.In terms of DEX, Charles believes that the evolution of DEX can be viewed from the two dimensions of technology and governance. In the long term, DEX will dominate, but this will not be achieved in one step. Exchange needs to gradually evolve from a form of centralization, in both technology and governance, to decentralization in the end.Regarding the future of blockchain, according to Charles, those fields related to value, such as payment, will see usage of blockchain sooner. In the future, blockchain can become a carrier of contracts, laws, and mediums of value exchange between people and machines, or solely between machines.Highlights:“My personal feelings about the market is that we are in a transition period from a bear market to a bull market. The worst time has passed, but the bull has not yet come.”“Don’t take shortcuts. They are often traps. Regardless of investing a company or starting a new business, you must insist on doing the right thing, not the easy thing.”“How blockchain will be adopted in specific scenarios, is the new story of public chain.”“How to deal with the tradeoff between cost and security, is the key problem to be solved by public chain.”“In the long run, DEX will dominate. To achieve this goal and create a perfect DEX, many efforts must be done. Instead of going from one place to another in one step, there will be many intermediate processes.”“Always insist on doing the right thing rather than the easy thing. When facing difficulties, choosing to do the easy thing is the weakness in human nature. Over-obsession with shortcuts can lead to great trouble.”---------------------------------------------------------------------------------------------------------Binance Sisi: Hello everyone. Today, I am honored to invite Charles to our program. Now let’s say hello to Charles. Hi Charles, welcome to Block 101. How about giving us a brief introduction first?Charles: Hello everyone, so glad to attend this Block 101 live broadcasting program. I firstly got to know cryptocurrency and blockchain in 2013. In the next year, I started my company in this space, which was a crypto exchange. I established Vite two years ago. That is the public chain project I’m working on now.Binance Sisi: We are also interested in the channels that you usually use to learn about blockchain?Charles: There is no secret. Similar to everyone, I mainly learn from the Internet, including professional media and independent media. My first-hand information often comes from friends or social groups. If I want to know more about a project, I will read the project’s white paper and the code if necessary.Binance Sisi: This is too hard-core, I feel that many people can’t do that. I will bring up a topic that everyone is concerned about. How do you look at the market? Is it a bear market or a bull market for now? If it is the bear market, how long do you think the bull will come?Charles: Everyone has different answer to this question, and there is no standard answer. My personal feeling is that we are in a transition period from a bear market to a bull market. The worst time has passed, but the bull has not yet come.Let me also share more details behind this thinking. Bull market and bear market reflect the group psychology of people used in value assessment. When everyone is in FUD about an industry or investment space, it is a bear market. On the contrary, if everyone feels that the industry has great prospects for development and wealth, people will become excessive optimistic, even greedy. There are over-hyped visions, and bubbles are created in the market. This is a typical bull market. At this moment, just like you can feel, it is neither the worst bear market nor a bull market. The market is in transition, and a bull market is yet to come.Binance Sisi: I have interviewed so many industry leaders. The answers are very close, it is like everyone is optimistic about the second half of this year and next year.Charles: Yes, personally I am cautiously optimistic about the second half of this year. I am more confident that the market will have a better performance in the next year.Binance Sisi: Charles, I’ve read your profile, you graduated from the University of Science and Technology of China. This is too brilliant! Can you please share some thoughts how you were admitted? Do you feel any gap between your original dream and the reality?Charles: When I was a kid, my dream was to be a scientist and change the world with technology and innovations. I wanted to create a better life for the mankind.When I went to middle school, people often asked, “What are your tips for doing so well in school?” My answer was very short, “The tip is there are no tips”. I never thought about finding shortcuts, such as which reference book to read, where to get the exam paper, and so on. What I want to say is that it is the same when we do a business or investment in crypto space. It is very important to not try finding shortcuts, because there are often traps along with such shortcuts. When we want to make money or run a business, just do the right thing, not the easy thing. Do not attempt to make quick money.Binance Sisi: This industry never lacks people who want to take shortcuts. People said blockchain was scam, at the beginning I thought that way too. I am curious for a highly educated man like you, have you been influenced by those thoughts?Charles: My mental journey is similar to yours. I was in doubt when I firstly touched this industry. I was wondering if the whole thing was just another Ponzi scheme. I spent a lot of time thinking about the following questions. Is there any real value to the blockchain? If so, where is it? Why are there a lot of hype and bubbles, and many of them are speculation or even scams? Why is this happening?I recently read a book named “The Great Game”, which tells the history of Wall Street in the early years and how the US financial system was established step by step. What are happening in cryptocurrency today happened in Wall Street before. Pumping, dumping, various Ponzi schemes, speculations, all of these happened in the history of Wall Street, where some people made a fortune. History is amazingly repeating itself in crypto.Speculation and irrational growth are normal phenomena in the early stage of an industry. They do not represent the essence of the industry, however. In today’s Wall Street, the Internet companies listed on Nasdaq are backed by real value, real technology, real business models and real users. It is no longer in the stage of “irrational growth”. In its path of evolution, the blockchain industry will certainly enter and leave this phase of irrational growth.Therefore, I am not surprised by some problems in the blockchain. We should take a long-term view to see if blockchain technology adds real value to the society. We cannot overestimate the short-term value or underestimate the long-term gains.Binance Sisi: According to your work experience, you were a senior architect in and a technical director in Meituan Dianping. So what made you leave top Internet companies to join blockchain?Charles: I worked in the Internet industry for many years, mainly in technology and management. I have accumulated enough knowledge of this industry. Why leaving an Internet firm to embrace blockchain? It’s not hard to answer. Here I can explain with an analogy. From the perspective of development trends, the traditional industry belongs to yesterday, the Internet belongs to today, while the blockchain belongs to tomorrow, and the future.The development of the Internet has now entered a highly mature stage. The industry is in a red sea. I still want to invest for the future and do something more interesting and cool.Binance Sisi: Why did you establish Vite? What was the original intention?Charles: I think the development of blockchain has made a lot of progress at the technical level. There are many explorations and attempts, but still it has not been adopted by large-scale commercial applications. In other words, it has not really become useful. There must be something missing. I want to fill this gap and create a blockchain that can really be used.、Binance Sisi: Someone said that the story of public chain has finished, what do you think?Charles: I think the story of public chain is not finished. On the contrary, it is just at the beginning. In the past, there were many stories, including the stories of public chain 1.0, 2.0, and 3.0, as well as how to solve security, scalability, decentralization issues and improve performance. These topics were mostly technical, in terms of how infrastructure can provide higher efficiency and lower costs.How to create business models on infrastructure and build useful applications is a more exciting story of the public chain. I call it “Blockchain+”, which particularly specifies usable scenarios that apply to real economy. This is the new story of public chain.Binance Sisi: Any specific story for public chain in the future?Charles: Depending on the specific usability scenarios in the future, we should not only pay attention to the performance of the underlying infrastructure, like consensus algorithm, protocol, new technologies such as sharding. These are all about technology.We should also look at what scenarios or technologies the public chain is able to integrate with, in order to create real value for our daily life. In one word, we should solve the pain points, and turn what we were not doing well into reality.For example, the integration of blockchain with traditional Internet, 5G, artificial intelligence and autonomous driving will bring much imagination and value. I think they could be the future stories.Binance Sisi: Can you comment on the public chains at present, such as EOS and Binance Chain. What are the differences between Vite and these public chains?Charles: The existing public chain projects now have both the similar and different elements. The common problems, such as solving decentralized trust and network cost, must be addressed by all public chains.The goal of each public chain is different. The reason why there are so many public chains is because the demand is diverse. One case is payment. The demand for payment varies in different scenarios. For example, if you buy a house, you have to pay a lot of money. At this time, your demand for the payment is not fast, but safety. But if you buy a bottle of water from a vending machine downstairs, comparing to safety, the efficiency of payment is more important. In this case, if you pay with Bitcoin for the water, you will realize that the cost is very high due to high transaction fees on Bitcoin network, and the efficiency is very low due to large latency. The water may cost you $2, but the transaction fee is $6, not to mention that you have to wait for 10 minutes before you can get the water from the vending machine. Obviously, Bitcoin, as a well-known public chain, is not good at doing this.In most cases, it is common for public chains like Binance Chain and Vite to process frequent micro transactions. One scenario is DEX, where operations like placing order and canceling order are taking place on chain. In this case, even manual operations happen frequently. It will be inappropriate to implement a trading bot on public chain like Ethereum or Bitcoin. This is the reason why Binance Chain and Vite are designed into a high-performance public chain.Unlike Binance Chain, Vite mainly focuses on how to reduce cost. We want to provide a public chain completely free. Whether you’re making a transfer or calling a smart contract, there are no fees. This is the biggest advantage of Vite.Binance Sisi: What do you think matters most for public chain?Charles: The public chain is an open system, and the security is the most important. Actually, prevention from malicious attacks can cost a significant amount. For example, in order to mine Bitcoin, you need to have sufficient hash power which requires ASIC miners of the latest model and a huge consumption of electricity. They are the costs paid for security.How to handle tradeoff between cost and security is the key issue to be solved by public chain. If the security is the only thing we are concerned with, every transaction on the chain could involve a huge cost, and the public chain will be useless in practice. Actually, many applications don’t need extreme security. From another perspective, security cannot be totally abandoned. If a public chain is hacked due to security vulnerability, the blockchain may fork, user’s assets may get lost, and, in the worst case, the entire network may collapse. Therefore, we must look for a balance between security and cost, which is the essence of public chain.Binance Sisi: What is the difference between public chain and consortium chain?Charles: Blockchain has a core concept — decentralization. Everyone has heard of it. In my opinion, “decentralization” can be interpreted in two ways of technical implementation and governance.From a technical point of view, decentralization refers to distributed ledger. Generally speaking, there are many computers in the network, and they must reach consensus according to the algorithm.From the perspective of governance, it means that in an open system, instead of relying on a central authority to make decisions, it is up to many participants to form a mutual system, running under the constraints of certain rules, jointly making decisions and supervising the execution of the decisions.You will see that in the blockchain space, some projects only need to be decentralized in the technology sense, but not in the governance sense. For example, private chains or consortium chains are tamper resistant and traceable, but it is not necessary to implement decentralized incentive models and community governance.In turn, some projects only adopt decentralized governance. Platform coin issued by centralized exchanges is such an example. Before the launch of Binance Chain, the presence of BNB stands for a form of decentralized governance. BNB holders can jointly decide what cryptocurrency will be listed on Binance exchange and can even share the exchange’s revenue, but the exchange is still implemented in centralized technology. Another example is the mining pool. There are many miners in the mining pool. Any miner in the pool who mines a block will share the mining rewards with all miners. In this case, the organization is decentralized, but no decentralized technology is used.Binance Sisi: What is a token-free blockchain? I am also curious.Charles: Let’s think about what role the token or coin plays in the blockchain. Tokens in blockchain are mainly an incentive for decentralized governance. The token of Bitcoin is invented to incentivize Bitcoin miners. In this case, users need to pay miners with Bitcoin as transaction fee. Decentralized governance systems must take incentives into account, and the most widely used method is through tokens.Although the token-free blockchain also uses blockchain technology, it is not a decentralized governance system. It is usually operated by a company or government agency, and relies on strict access control and laws to limit and punish bad actors.Binance Sisi: Someone in chatroom just raised a question to Charles. Charles, can you comment on Loopring and your former partner Daniel Wang? Thank you.Charles: In 2014, Daniel and I co-found a crypto exchange. Daniel was the CEO and I was the COO. We share similar values. We both pay attention to the fundamentals of a project and focus on “doing the right things”, because we have seen too many lessons of others in the crypto space.Meanwhile, Daniel and I both have an “exchange dream” because we believe exchange is a real scenario where blockchain can be truly useful.Binance Sisi: Let’s talk about Vite. Can you tell us the current status of the Vite community? Also for the future plans, what are the goals and missions?Charles: Most of the Vite team is located in China. We have two offices, one in Beijing and the other in Silicon Valley. The development is done in China, however, we have a big international community and users distributed across 190 countries in the world.For example, the top 5 user groups of the Vite mobile app are from the United States, Russia, Vietnam, Indonesia, and China. The DAU is about 20,000.At present, the real transaction volume on the Vite public chain is large. Where does the volume come from? The main reason is that Vite is not an idle chain, and there is a high frequency application — ViteX. The current trading volume on ViteX is around 100 BTC per day, which is a satisfactory number for a DEX.We have also made attempts in payment. Now there are a bunch of merchants in Singapore accepting VITE. In Singapore, you can use VITE to pay taxi fare from the airport. There is a five-star hotel in Singapore called CÉ LA VI, where in the SkyBar on the top floor of the hotel customers can spend VITE for meals. In the long term, we have plans to serve more merchants.In addition, we are also exploring the cooperation with government. We entered into a pilot program with the American city of Syracuse to launch a project naming “Syracuse Coin,” to tackle local housing issues for low-income residents. In China, we created the “Anti-epidemic Materials Tracing Platform”, particularly for fighting with Covid-19 outbreak.Binance Sisi: Recently, the topic of DEX is very hot. Charles, what do you think?Charles: In fact, DEX has been explored by many parties for a long time. For example, Binance has launched Binance Chain and Binance DEX. Vite continues to explore in this space and is doing a great job.Let’s look at the evolution from centralized exchange to decentralized exchange, from the two dimensions of technology and governance. In the long run, DEX will definitely dominate in the future, but this will not be achieved in one step. Exchange needs to gradually evolve from a form of centralization, in both technology and governance, to decentralization in the end.I have seen many DEX projects follow this path to move toward decentralization, in terms of tech and in terms of governance.How does an exchange match orders and conduct settlements on-chain? This is the technical perspective.From the governance perspective — Although the exchange is deployed on the chain, there are still design choices for how to distribute revenue, and how to modify emission rules of platform tokens. These items also need gradual transition from centralization to decentralization.For a DEX, if only on-chain matching and settlement is implemented, but there is no decentralized mechanism to determine listing decisions and dividends, it cannot be called a “true” decentralized exchange.The governance’s transition from centralization to decentralization usually takes a cold start first. Here I highly agree with the ideas of CZ, by starting with a centralized governance model, and then gradually transitioning to community’s governance.In the future, whether a DEX is truly decentralized in both technology and governance, is the new story of DEX.Binance Sisi: Till today, there is no convincing scenario for blockchain to integrate with the real economy. So where do you think the blockchain will most likely fit into the real economy in the future?Charles: Blockchain represents the future. In fact, blockchain is not a technology nowadays. Although today the blockchain technology seems kind of incapable, if you look forward to the future, you will understand that the blockchain really matters, and some jobs can only be performed by blockchain.At present, most of usable scenarios are related to value, in terms of value’s storage, circulation, and exchange. They are represented as payment gateway, DEX, and DeFi in the end products.I have a long-term vision. With the development of AI, our daily life and social organization will change in the future. For example, it is not hard to imagine that there is no taxi driver when the self-driving technology matures, and what are present on the road are all driverless cars. The society is composed of people and machines. Since AI will play a much significant role in the society, the original system of people will not work after the machines join in.In the current society, people are regulated by law, which is entitled by national power. People are not robbing banks and committing murders out of fear for losing their freedom and life. If a society is constituted by machines, the current legal system is no longer effective because machines are not afraid of going to jail or being killed. They will break the law. At this time, the blockchain, as the next-generation social contract across machines, and the value transmission medium between people and machine, must emerge to regulate machine behavior.People take driverless taxis. How is the passenger chosen? Is there a detour made? How to judge the responsibility of traffic accident? Blockchains are best suited to answer these questions. The more the development of science and technology, the more the importance of blockchain.Binance Sisi: Well, today I asked a lot of questions that we want to know. Thank you very much Charles. Thanks for coming to Block 101. We look forward to seeing you again in our future live broadcasting.Charles: Thank you all, and thank you Sisi.Link to Video: Block 101 : Exclusive Talks with Charles Liu — The New Stories of Public Chain and DEX was originally published in Vite Labs on Medium, where people are continuing the conversation by highlighting and responding to this story.

Vite Insights: How to Effec...

This article is written by Vite Labs COO Richard Yan. If you have any comments, please reply to All rights are reserved by Vite Labs.It is no secret that Vite Labs is a global team. Our community knows that our R&D team is based in Beijing, and our international operations & marketing team is based in Silicon Valley. In addition, one of our business development managers is in New York City. And our community managers are in Ukraine, Vietnam, Germany, Japan, the Philippines, Brazil, Turkey, Indonesia and China. The recent coronavirus situation requires many in our regional offices to work from home, which further decentralizes our team.The geographical dispersion, timezone difference, along with cultural and language disparities create challenges for effective collaboration. But through careful planning and disciplined execution, we believe we have largely overcome said difficulties. That is, to a large extent, we’ve been able to make sure all colleagues are kept updated of the R&D progress, follow the upcoming marketing roadmap, and feel a sense of belonging in one family.For other projects and anyone working in a global team environment, here are some tips that might be helpful.Infrequent and effective meetings preceded by detailed agenda write-upAt Vite, team members communicate with each other via real-time apps like WeChat Work and Telegram. But we emphasize the importance of writing long-form, thorough pre-meeting plans on our internal wiki’s (Confluence). Writing helps the meeting organizer think through the outcome they want from the meeting and pre-communicates details to maximize preparation from participants. Sometimes, writing such a pre-meeting plan may obviate the meeting altogether, as all key points will have been conveyed in advance. Here, we borrowed a page from Amazon’s pre-meeting memo requirement.The art of asynchronous collaborationAcross different timezones, inter-dependency collaborations could get frustrating. Imagine collaboration on a marketing campaign between two team members, A and B, in Beijing and San Francisco. A sends B raw materials, B adds to them, and then A finalizes the campaign document. All of this is happening asynchronously, which means when A is sending B a message, B is off the clock; and vice versa. If A does not send everything B needs to do her work, B’s progress may be blocked for 24 hours. At Vite, for cross-timezone communications, we encourage each team member to put themselves in the shoes of their remote collaborator, and be thoughtful and exhaustive about providing items the other person needs in such asynchronous communication.Sometimes it’s not about incompleteness of communication. But mis-communication. To combat this, we encourage repetitive communications. This doesn’t mean copying and pasting the same message multiple times. Instead, this means stating the same thing multiple times in different languages (if applicable) and stating clearly the converse (i.e., “this is what I want, and this is what I DON’T want”).For more on this, Basecamp has great insights on communications for remote work.Regular team happy hours, or “hangouts”Culture not only makes work fun and pleasant. Culture also gets the team so fired up about work, that they think about work during off-hours, and make positively surprising contributions (a novel idea, or going the extra mile on a project). One way to strengthen cross-timezone culture is to run regular online happy hours. At Vite, this means community hangouts on Telegram, where Beijing, San Francisco and our global community managers have a long, free-form discussion on Telegram. We do this at different times of the day to accommodate different timezones. Sid Sijbrandij of the all-remote company Gitlab (1300 employees) talks about global pizza parties that serve a similar purpose.Chat room hygiene: Policies to separate work chats from leisure chatsIt may seem trivial, but colleagues’ divergent expectations for chat room behavior can lead to unpleasant outcomes. Our more bubbly and outgoing coworkers love using emoji’s and GIF’s, or are in the habit of discussing crypto-adjacent topics in work chat rooms. Simultaneously, our more engineering-minded coworkers prefer strictly professional talk and dislike sorting through frivolous or tangential materials for essential work items. The easy solution is to create a separate chat room dedicated for fun, and set rules for discussions in chat rooms of a more serious nature.Objective performance reviewsPre-determined and publicized metrics, with proper definitions and weightings, make the review process less arbitrary, and make the results more easily acceptable to reviewees. This is certainly true for non-remote work, but even more so for a remote team. At Vite Labs, our sub-teams each have a review system. In general, teams with daily, in-person interactions have a peer review system; and teams that are largely remote have a manager review system. Regardless, clear objectives are set at the beginning of each review period, and managers have 1–1 with team members to share review results and collect feedback.ConclusionThe future of work may become ever more remote, thanks to the pandemic situation we are in. Indeed, Coinbase, Twitter, Shopify and other major tech firms have announced that all or a substantial portion of their workforce can expect to work from home indefinitely. Effective management of remote teams will become an essential skill for new business leaders. At Vite Labs, we are proud of the way we have led our decentralized and international team so far. And we look forward to perfecting our practice and continuing to deliver on our commitment to the community.Official: Official: Forum: https://forum.vite.netTelegram:English: Insights: How to Effectively Lead a Decentralized Team was originally published in Vite Labs on Medium, where people are continuing the conversation by highlighting and responding to this story.

A Call for Community Input ...

A Survey for New Products/Services for ViteDear Vite community,Time flies! Vite is now two years old since we first published our white paper in 2018.In the past two years, we delivered the Vite public chain, ViteX DEX, Vite app, Vite block explorer, Vite API/SDKs, Vite Pay, Vite Store with many upgrades and improvements along the way. We are particularly proud of the Vite app, a one-stop shop for all things Vite, including a multi-chain wallet and ViteX.Having delivered nearly all key items we originally set out to create, we are now ready to undertake more ambitious missions. And we enter this new phase with a product-first mentality, the idea that we want to build things our community truly needs. We hope this mindset has been clear to you all along. “Making something the community needs” is, after all, aligned with the crypto ethos of decentralized governance.Indeed, in the past, we’ve found that many great product decisions came from the community’s input. Recent examples include VX’s release curve, excellent altcoins to integrate on our gateways, and the stablecoin zero-fee conversion feature.Therefore, today, we are asking you, our community, to share your ideas for what systems/products/tools/features Vite should build next. Please complete this short survey: suggestion is too big or too small. They can be related to DEX, public blockchain, wallet, or anything else in the crypto universe. They don’t need to be anything on the current roadmap. And indeed, your ideas will be pivotal as we consider next steps in our roadmap.(By the way, watch out for an oncoming review of our Q2 deliverables in a separate note)Now, of course, as a matter of practicality, not every idea will be implemented. But at this stage, we would like to keep our mind as open as possible in hearing your ideas that would shape the future of Vite.Thank you!Charles LiuA Call for Community Input from Vite Labs CEO Charles Liu was originally published in Vite Labs on Medium, where people are continuing the conversation by highlighting and responding to this story.

Tech Series #5: Inside Vite...

As a high-performance decentralized exchange, ViteX implements both matching engine and economic model in the built-in contract vDex, satisfying both design simplicity and system robustness. In the previous article “ViteX Contract Design and Implementation”, we have discussed the design details of ViteX. As a follow-up, this article focuses on a few FAQs to further explain the background, issues and solutions.Why vDex is implemented as two contracts, not oneIn ViteX, order matching and economic model are two important but irrelevant functions so that it does not make sense to put them in the same contract, which may cause confusion for developers and API users. In addition, matching engine is a basic function for exchange, it will be easy to upgrade independently after decoupling from the economic model. Based on the thought, we separated the functions as contract dexFund and contract dexTrade. DexTrade implements ViteX’s order book and order matching engine, while DexFund performs functions related to the ViteX economic model such as asset management, mining and dividends.2. Why two types of order id are usedWe studied the structure of order id in the previous article. The order id, referred to here as baseOrderId, is designed to maximize performance boost through on-chain order sorting and efficient matching. In the “Stem” hardfork of Vite, a new order id, hashOrderId, was added too. As the name indicates, hashOrderId is composed of the value of transaction hash in which the order is placed. Unlike baseOrderId is generated by contract, hashOrderId is created when the order is placed by user without waiting for vDex’s response, which makes it possible to be used for convenient order status tracking and perform subsequent actions accordingly. In summary, hashOrderId is often used by client program like trading bot while baseOrderId is designed for improving matching efficiency.3. Why two order cancellation interfaces existBecause the ViteX’s order book is stored in dexTrade, and to cancel an order only the order book has to be accessed, so in early version of ViteX the interface of order cancellation is in dexTrade. However, order placement is based on the dexFund contract in the purpose of locking up funds, which leads to inconsistent design for order placement and cancellation. In the actual execution of the contracts, an order, after placed, may immediately be cancelled before it is written into the order book in dexTrade due to on-chain consensus delay. At this time, the cancellation fails since the order does not exist in the order book. To address the issue, we have added a cancellation interface in the dexFund contract in recent fork “Mars”. In the new design, for an given order, the guarantee of sequence of requests on user’s account chain ensures that the cancellation request will definitely be processed by the smart contract after the order is placed. Comparing the two interfaces, the new one produces deterministic execution result at a cost of introducing an additional step to pass the cancellation request from dexFund to dexTrade, and is recommended for automated trading tools to use.4. How to improve the performance of order matchingTo improve the speed of order matching, the common practice is to put the best orders or all orders into memory for efficient access. However, for smart contract, due to the limited ability to access the storage provided by the blockchain, the order book cannot reside in memory. At this time, one way to consider is to make full use of the underlying storage to ensure that the order book is stored in an orderly manner, so that the matching process only requires sequential iteration. By using price as part of order id and using order id as the storage key of levelDB, the matching process can be completed by a simple key sequence traversal. This solution is simple and highly efficient.5. How to reduce storage occupationThe cost of on-chain storage is extremely high. In order to minimize data storage, we have adopted the following approach. First, serializing objects through Protobuf to reduce the size of data. Second, avoiding redundant data storing. It is mainly reflected in the processing of indicators related to mining and dividends. If an indicator has not changed for a time, only the earliest value is stored. Third, using both real-time cleanup and regular cleanup. For the multi-version indicators accumulated in mining and dividends, old data are deleted in real time for the indicators have been updated. Regular cleanup applies to order book. In order to avoid unlimited expansion of the order book, a timeout timestamp is set for each order and expired orders will be recycled regularly.6. How to increase the reliability of vDexAs built-in contract, each line of code of vDex is written protocol. Simplicity and reliability must be fully addressed. Over-design would increase the code size unnecessarily, as well as the number of bugs and errors in the end. Based on the principle of simple design, the data structures of vDex are as simplified as possible. Only core data that usually won’t change are stored on chain and other non-related information is stored off-chain. ViteX’s off-chain data service supports sophisticated query and data display. At the code level, we restrict the number of lines of code for a single function. By splitting functions, naming function with meaningful name, code duplication is also reduced. The target is to make the code clean and easy to read. Finally, the built-in auditing function will regularly verify the correctness of contract execution result, ensuring the safety of user’s assets.Official: Official: Forum: https://forum.vite.netTelegram:English: Series #5: Inside ViteX’s Built-in Contract was originally published in Vite Labs on Medium, where people are continuing the conversation by highlighting and responding to this story.

The pool of undistributed dividends stands at 31.8 BTC.ActivitiesOur COO Richard released a new episode of the Blockchain Debate Podcast. The latest debate topic is “Motion: Corporate bailouts and capital market rescues make sense, Part 2.” The guests are Nick White, co-founder of Harmony and Jonathan Padilla, head of Blockchain from Paypal. The discussion is around the legitimacy of QE by global central banks and bailouts of essential businesses by governments around the world. Cryptocurrency was born out of concerns for currency debasement and invisible tax as a result of these policies. As such, this debate is directly related to the existential reason for cryptocurrency.Our COO Richard also ran a new regularly-scheduled community AMA. The purpose of the AMA is to increase our transparency and quickly iterate product features upon the community’s suggestions. As such, we will continue to conduct these AMA sessions.We provided detailed response to questions from the community. See transcript here: The questions fall in these three categories:Status update of Q2 roadmapMarketing and evangelism of ViteXDetails of partnerships with other projectsVite had an internal community manager hangout with participation from our core community managers (English, Russian, Vietnamese, Arabic), where we jointly planned on multiple marketing campaigns. These campaigns include AMA with the communities at well-known exchanges and contest for coin-listing recommendation.We sent a survey to the community in regards to local economies. 104 members from 30 countries responded. Per this research, we saw a positive correlation between interest in crypto from high net worths and the deterioration of economic situations. A whopping 30% of respondents are highly suspicious of the integrity of local banking systems. Venezuela, Nigeria, Russia, Turkey and Ukraine are experiencing severe inflations. In particular, daily groceries in Venezuela are quoted and settled in USD, and local residents regularly convert from fiat to crypto. Here’s the summary of the research:, members of our international community created multiple social media accounts to help Vite with marketing, for which we are deeply thankful!Here are a few tweeted a video celebrating two-year anniversary for Vite.

Vite Bi-weekly Report

May 16–31, 2020Recent MilestonesVite Labs Plans to Integrate Chainlink OracleOracles are important for Vite’s ecosystem development. High-quality oracles ensure reliable, diverse and decentralized off-chain data feeds. Chainlink is one of the longest-running and best-known oracle technology providers. After integrating Chainlink oracle, Vite will bridge the on-chain and off-chain data gap, more efficiently integrate decentralized systems with traditional centralized systems, further expand the function of the Vite gateway, and lay the foundation for building and improving applications such as decentralized derivative trading, VitePlus, VitePay, crypto ATMs, blockchain-enabled IoT, and more.Technology SeriesOn May 27, we released the technical article Design and Implementation of ViteX Back-End Service. This article explains built-in smart contracts within ViteX, from three angles: design, performance and system reliability.Vite Community Star ElectionOn May 20th, we released the Vite Community Star Global Election Campaign. The selected “Community Stars” will be displayed on the new version of Mentions on Twitter SoaredPer XTrading, Twitter mentions of Vite increased by 331% over the last month. This growth rate ranked #2 among all cryptos tracked.Data on ViteXAs of June 1, 18,042,819 VITE have been burned, accounting for 1.8% of total issuance.138,435,458 VITE are staked on ViteX exchange, accounting for 13.83% of total issuance.7,110,327 VX has been released, of which 6,563,963 VX is being staked for dividends.To-date, 58.4 BTC worth of dividends have been distributed. The pool of undistributed dividends stands at 32 BTC.System DevelopmentsVite AppVite App V3.7.0 has been finished developing. On May 28, we submitted iOS version to the App Store for review. On May 29, we submitted Android version to Google Play for review.V3.7.0 mainly solved the following problems:Rewriting the transaction detail page in native code. In previous versions, when users viewed the detailed information of Vite transaction records, it jumped to H5 page of the block explorer, which took a long time to load, and cannot copy fields such as address and transaction hash. In V3.7.0, when users click on transaction record, the transaction details will be displayed directly in the App. The user can also copy address, transaction hash, and other fields with a smoother experience.Optimization of the exchange page. After the V3.6.0 was released, users provided us with suggestions for improving the exchange page experience. We have optimized it in V3.7.0. These optimizations include:No prompt of quota consumption will be displayed before the order is placed or cancelled.Users will be asked to confirm the pending order about price and quantity after clicking “buy” or “sell” in order to avoid mis-operation of placing an order.Display of order positions have been added to the candlestick page and the trading page.Maximum quantity limit has been added at the amount of buying/selling. A prompt of “insufficient balance” will no longer be displayed.“+” and “-” buttons have been added to the price and quantity input area, which is easier for changing price or quantity.A prompt of effective market-making order ranges has been added.Renamed Comment in English. Recently, there were feedbacks about where to fill memo when transferring VITE to Binance or OKEX exchange. Therefore, we renamed Comment to Memo for the habits of our community.We have fixed some bugs in V3.7.0. For example: the missing of candlestick subscription data; incorrection of price automatically filled when the order page is switched to buy/sell.ViteX ExchangeOn May 27, Vite Mainnet successfully completed its fourth hard fork. ViteX built-in contract has also been upgraded. As of now, Vite Mainnet is stable and has a normal block production rate. New functions have all been effective. After this upgrade,ViteX order operation logic from clients and API will remain consistent, and the result of order matching will also be deterministic.In the previous version, the candlestick data needs to be calculated locally on the client side, resulting in data out of sync among different clients. In the new version, we have optimized the candlestick service by calculating data on the server side to secure data consistency.In addition, the official ViteX Python SDK and Java SDK have been developed and will open source soon.Official Website UpgradeAfter the community vote, the design style of the new official website has been determined. At present, we are revising according to the selected design style, and optimizing the content of the website.ActivitiesOn May 22, our BD Director Isda, core developer Jie, and Marketing Manager Christy participated in the “Pizza Day Carnival” organized by Jinse Finance and Huobi, and commemorated the “festival” with many Chinese blockchain practitionersOur COO Richard hosted Messari’s advisor Qiao Wang and Bitcoin maximalist Jimmy Song on a new episode of The Blockchain Debate Podcast. The topic was on corporate bailout and capital market rescue. This is on the back of unprecedented amount of quantitative easing from the US Fed. The crypto-native narrative is that such actions would enable growth of bad debt fueled by excessive liquidity and rob the people of their wealth by increasing prices of goods and assets. As such imprudent monetary policies created the need for crypto, this debate topic is apt for the crypto community. As previously mentioned, this podcast is one way for us to expand our brand recognition and network with industry thought leaders.All episodes are available at: https://blockdebate.buzzsprout.comYou’re also welcome to follow Richard ( and the podcast ( on Twitter.On May 21, our COO Richard conducted an AMA in Vite telegram group, answering over 20 questions from the community including suggestions for product improvement and marketing plans.

Vite Insights: Vite Survey ...

This article is written by Vite Labs COO Richard Yan. If you have any comments, please reply to All rights are reserved by Vite Labs.Cryptocurrency at its heart is an economic phenomenon. Cryptocurrency’s ethos of sound money and disintermediated financial system were born out of a world of irresponsible currency debasement and inefficient and corrupt banking. We at Vite recently conducted a survey among our global community, to check the temperature on economies around the world, where Vite enthusiasts dwell.This survey confirms our view that interest in crypto as an asset class is positively correlated with declines in economic conditions. Our questions are about local economic conditions and how people are making decisions regarding their wealth allocation. The responses show that the world economies are in shambles, public trust in banking institutions is extremely low, and there is significant interest in moving assets into crypto by each country’s wealthy citizens.Survey DemographicsThe survey was completed by 104 members of the Vite community across 30 countries. The top five most represented countries are: Nigeria, the Philippines, USA, Turkey and India. About 30% of the respondents’ countries are from G7 countries.Countries represented in the surveyHere is a quick glimpse of their backgrounds. The top five professional categories are students, engineers, freelancers, unemployed, and sales.Professions represented in the surveyAbout two-thirds are currently required to stay home due to local lockdowns. Let’s not forget that the coronavirus has been the nail in the coffin for many deteriorating economies, a sentiment reflected in many comments from the survey takers.Survey takers required to stay home due to coronavirusConfidence in the EconomyWe asked about prospects of jobs and sentiment regarding local economy, real estate, and stock market. Unsurprisingly, the results are quite bleak.Upward mobility is not strong. About one third said it would take them more than six months to find a job with a higher salary.Time it takes to find another job with higher payAlarmingly, a whopping 37% believe their countries are facing imminent default of national debt.Opinon on countries facing imminent default of national debtInterestingly, this view is not too different between G7 and non-G7 nations. Below is the same chart for G7 nations only.Opinion on countries facing imminent default of national debt, for G7 onlyAbout 40% feel pessimistic about their country’s future economy. Below, 1 = very pessimistic, 7 = very optimistic.COnfidence in economy, 1 = very pessimistic, 7 = very optimisticAlmost 50% believe that real estate market (for the most developed city in their country) will decline in the next twelve months. More than one-fifth believe the market will be down by more than 20%.Survey on local real estate market in next twelve monthsAbout 56% believe that the stock market will drop in the next twelve months. About 28% believe the market will tank by more than 20%.Survey on local stock market in next twelve monthsThe respondents’ detailed accounts of their local and personal circumstances are illuminating. The complaints about local economies at non-G7 nations are especially severe. Here is an example from a Brazilian community member, who keeps 100% of their wealth in crypto, as she feels completely disillusioned by the failure of the state. Here’s her comment, lightly edited for clarity:I think (the Brazilian) government will disappear. Most basic services in Brazil have been halted or are offered at a minimum due to imprudent fiscal management…That is why I am 100% in crypto.In a separate discussion between her and the survey organizer, this person offered other details:Regular local protests are disrupting traffic, hence preventing timely re-stocking of inventory at supermarkets and provision of petrol at gas stations. The under-funded postal service has been reduced to only twice a week. Hospitals are understaffed or have strike-induced closure, which was a big problem for her when she had an allergy emergency.Confidence in Banking & MoneyWe asked about inflation, corruption in banks, and how people are allocating their wealth.15% sees strong inflation. Venezuela, Nigeria, Russia, Turkey and Ukraine have the highest percentage of reports of strong inflation.In survey comments, we see that in Venezuela, due to hyperinflation, the currency is so untrustworthy that even groceries are priced in USD. And in Ukraine (and in Venezuela), real estate prices are quoted in USD.Current inflationTrust in banks is extremely weak. 30% think their banks are very corrupt. Of the respondents that consider their banks trustworthy or have no comment on corruption, about 10% indicate extremely high fees or interest rate at these banks.Opinions on local banking systemWealthy citizens are eager to move their assets into safer stores of value, such as reserve currencies, precious metals or crypto. A whopping 62% of respondents think their nation’s wealth class is moving assets into crypto. Otherwise, USD is the top “traditional” safe-haven asset, with 44% of the respondents agreeing that the wealthy are moving their net worth into USD. Note that allocations to these different stores of values are not mutually exclusive.Interest of wealthy individuals in moving assets to various stores of valueWe then asked each respondent for their own asset mix. About 90% own some crypto, and about a third allocate at least 40% of their net worth in crypto.Assets in crypto by survey takersAs previously mentioned, respondent comments with details are especially eye-opening.Here is the input from someone in France, who keeps 30% of their net worth in crypto (lightly edited for clarity):On banking: If I could, I wouldn’t use banking system anymore. The fees are way too high for simple tasks.On asset allocation: I am also Lebanese, and my second country (Lebanon) is the perfect example of inflation. People there are trying to get rid of Lebanese Pound since it lost its value more than 2 times. Everyone is trying to convert to USD (second official currency) but banks don’t have enough of it. USD is getting rare. So a few relatives of mine are also investing in gold to prevent a major crash.It’s worth noting that, amid the mostly gloomy answers regarding inflation, government debt and banking corruption, we do see very positive responses in these areas for two countries: Germany and Japan. But these two are exceptions than the rule.ConclusionThis survey confirms our prior about the state of the world’s economy and the extent of public interest in their respective countries’ future development. The coronavirus induced economic crisis will accelerate the accumulation of national debt, spur further money printing that debases fiat currency. This will also expedite the movement of assets into new kinds of money: Money that is provably scarce, has transparent and modest inflation schedules, and that will bring about efficient and cost-effective financial systems.What do you think of the survey results? Does anything stand out as surprising? Do the results jive with your local situation? We’d love to hear from you.

Tech Series #4: Design and ...

ViteX, a built-in decentralized exchange on the Vite chain, plays an important role in Vite’s ecosystem. ViteX is composed of a built-in contract (vDex) and an off-chain service (DexServer). Orders are matched in vDex, fully leveraging the benefits of blockchain — decentralization, safety and reliability. However, storing all the data on the chain is very expensive, and is not a good practice. In order to provide users with fast and efficient data query service, we designed the off-chain service DexServer, which is responsible for synchronizing open/historical orders, matching results, operational statistics and other metrics on the chain, and provides the query service.According to responsibilities, DexServer has four sub-services: Dex-API, Dex-Crawler, Dex-Push and Dex-Task. Among all the services, Dex-Crawler is the most important, providing data sources for the other three. The entire system flow is shown in the figure.Dex-APIDex-API provides the query interface for outside system, based on the final aggregation of the data generated by Dex-Crawler and Dex-Task.Dex-CrawlerThe Crawler service is the cornerstone of the entire system. Data crawled from the chain is formatted and stored in database, for subsequent use by other services. vDex consists of two separate contracts — dexFund and dexTrade. dexFund is responsible for operations such as deposit, withdrawal, opening trading pairs, mining, dividends distribution, referrals, etc. dexTrade completes order placement, cancellation, and matching. Dex-Crawler crawls the two smart contract chains separately, processes data, and stores in multiple forms as needed.The Crawler service completes three major functions — fork resolution, order book aggregation, and statistical indicators. There is an essential difference from the centralized trading system — rollbacks and forks naturally reside in the blockchain. Therefore, one of the primary tasks of the Crawler service is to determine whether the contract chain is forked. If it is, according to the height of the fork, some persisted data must be deleted in order to maintain synchronized with the state on the chain. Dex-Crawler uses the “previous block” of the blockchain and the database to detect whether there is a fork in the contract chain. If yes, it rolls back all the data at the height in the database to ensure consistency and correctness.Order book aggregation is the second focus of the Crawler service. When an order is placed, canceled or matched, the order book will change accordingly. Typically, it is represented to users as the order book’s depth has changed. The reason why order book aggregation is complicated is because it needs to group the order’s quantity and amount at the given (0 to N) decimal place in price for each trading pair. In order to improve performance, we employ the methodology of “in-memory modeling” to implement the aggregator. In this way, all processing is performed in memory, and then the output data is sent to Kafka for consumption by Dex-Push.Statistical indicators are the third focus. Whenever a new matching is completed, the indicators of Kline, Trades and Tickers will change. Since additional data sorting for different periods is required, Kline is the most complicated to implement. At present, the time periods supported in ViteX are [minute, hour, day, minute30, hour6, hour12, week]. All the indicators will subsequently be sent to Kafka for Dex-Push service’s consumption.Dex-PushThe job of Dex-Push is to display the data produced in the Crawler service to users in time. Cluster deployment is adopted to ensure the service is highly reliable and stable. In addition, in order to reduce server’s load, the client should initiate a ping request to the server once per minute to declare that it is alive, and the server will only send data to living clients.Dex-TaskThis service is used for operational statistics calculation and aggregation. Statistics of trade mining, market make mining, referral mining, dividends distribution, exchange fees and others are processed offline by scheduled tasks.This article introduced DexServer and its four sub-services. Asynchronous communications are performed between the sub-services to reduce coupling and improve robustness and maintainability of the system. In next article, I will introduce more technical details about Dex-Crawler and Dex-Task.

Vite Labs Announces Plan to...

SummaryVite Labs is excited to announce our plan to integrate with Chainlink, the market leading decentralized oracle network. Chainlink’s vast array of oracle features and services will be critical for launching various products that require off-chain data. Our initial planned focus will be on augmenting the value of ViteX and VitePlus.ViteX is a decentralized exchange built on the Vite public chain, a DAG-enabled smart contract platform. As examples, introduction of index and derivative products on the exchange would require off-chain data feeds. The second avenue of interest is for VitePlus, Vite’s blockchain-as-a-solution for government and enterprises. VitePlus will require a variety of “real-world” data feeds that are not native to the blockchain. Chainlink can provide the aforementioned data feeds.The Purpose of Oracles, and Why ChainlinkAn oracle is a piece of middleware that allows off-chain data to be consumed by a dApp and for a dApp to send commands/data to an external system. Off-chain data includes valuable datasets such as market data, health records, weather reports, and so on.Quality oracles are characterized by reliable data feeds with sufficient decentralization in both the oracle mechanism and the data sourcing. Insufficiently decentralized oracles create single points of failure and are subject to data manipulation attacks, especially as the value of the smart contract they secure rises. Having a fully decentralized blockchain using a centralized oracle compromises the end-to-end security of the smart contract application.Chainlink is one of the oldest and best-known decentralized oracle networks. Chainlink is the only oracle network that’s been battle-tested in production by a large number of projects that rely on its oracles for off-chain data.About Vite Labs and ViteXVite is a feeless and fast public blockchain. It is the world’s first DAG-based smart contract platform, well suited for commercial dApps with performance rivaling their centralized counterparts. Vite’s capabilities are made possible by its unique asynchronous architecture, hierarchical consensus, and snapshot chain. Vite has a steady record of deploying practical applications on its platform, with products including a decentralized exchange, a public-financing dApp for the American City of Syracuse, multiple game dApps, and micropayment platforms.ViteX is a decentralized exchange built on the Vite public chain. It is an open exchange run by the community, with its income passed through to the community. VX is the platform token of ViteX. VX holders enjoy the right of receiving dividends of transaction fees and other revenue of ViteX exchange.About ChainlinkIf you’re a developer and want to connect your smart contract to existing data and infrastructure outside the underlying blockchain, reach out here. The Chainlink team can help you quickly and securely launch your data-enabled application or Chainlink Price Reference Data Contract on mainnet today. You can also visit the developer documentation or join the technical discussion on Discord. Learn more by visiting the Chainlink website or follow its Twitter or Reddit.Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments. It is well known for providing highly secure and reliable oracles to large enterprises (Google, Oracle, and SWIFT) and leading smart contract development teams such as Polkadot/Substrate, Synthetix, Loopring, Aave, OpenLaw, Conflux, and many others.Official: Official: Forum: https://forum.vite.netTelegram:English: Labs Announces Plan to Use Chainlink for its Decentralized Oracles was originally published in Vite Labs on Medium, where people are continuing the conversation by highlighting and responding to this story.

ViteX Mining Guide

BackgroundViteX, developed by Vite Labs, is the world’s first DAG-based decentralized exchange. ViteX Coin, VX, is the coin native to the ViteX platform. It is mined exclusively by the ViteX community and is used to allocate rewards back to the community.VX holders can receive daily dividends from a shared dividend pool which aggregates all trading & listing fees accumulated by ViteX and redistributes back to VX holders.Overview: 5 Mining MethodsI. Trading as MiningTrade in BTC, ETH, VITE and USDT markets and receive VX rewards.II. Market-Making as MiningHelp improve order book depth by placing buy and sell orders and receive VX rewards.III. Staking as MiningStake VITE to help ViteX obtain higher level operational quota and receive VX rewards.IV. Referring as MiningGenerate a referral code to invite friends to join the ViteX platform and receive VX rewards.Inviter will be rewarded with 5% of all invitees’ trading as mining proceeds and 2.5% of their market making as mining proceeds.Invitees will enjoy 10% off platform trading fees, and receive an extra 2.5% of trading rewards and extra 1.25% of market-making rewards.V. Listing as Mining (Operators Only)Become a ViteX operator and list trading pairs to collect user transactions fees and receive VX rewards.Mining DetailsI. Trading as MiningMines approximately 60% of daily released VX. Currently, users are able to trade in four markets: BTC, ETH, VITE and USDT and receive VX rewards accordingly.Allocation: As mentioned above, ViteX is currently divided into four different markets: BTC, ETH, VITE and USDT. By trading in these markets, users are able to receive VX mining rewards. Each market will receive 15% of daily distributed VX.How to participate: By executing trades on eligible trading pairs and paying the corresponding trading fees, users mine VX (Trading as Mining).Mining reward calculation: VX rewards are calculated based on the proportion of a user’s daily accumulated trading fee to the total accumulated fees in each market. For example, for a given day, if a trader accumulates 5% of the total BTC market trading fees, then that trader will receive 5% of the 15% of VX rewards allocated to the BTC market.II. Market-Making as MiningMines 10% of daily released VX; BTC market at 5%, ETH and VITE market equally at 1.5%, USDT market at 2%.Placing orders on ViteX will also earn users VX rewards. The amount of VX earned depends on three factors: 1) the amount of order, 2) the amount of time your order remains on the order book, and 3) the amount of deviation from the best bid and best offer in the order book spread.Allocation: 10% of daily released VX; BTC market at 5%, ETH and VITE market equally at 1.5%, USDT market at 2%.How to participate:Only eligible trading pairs will be considered for market-making as mining rewardsBoth buy and sell orders are considered for market-making as mining rewardsOrders must not deviate from the designated mining range in the order bookMining reward calculation:The VX mining reward for market-making has a linear relationship with the order amount and order duration (i.e. amount of time the pending order stays on the order book). However, the mining reward has an exponential relationship with the order distance (i.e. the deviation from the best bid offer).For example, if Alice and Bob both place two separate orders for the same amount of token X. Both orders remain on the order book for the same amount of time. However, Alice prices her order on level 1 (i.e., extremely close to the best bid offer) and Bob prices his order on level 10 (i.e. further away from the best bid offer), the mining reward for Alice will be 100 times that of Bob’s. This system is designed to incentive users to place orders as close to the best bid offer as possible.III. Staking as MiningBy staking VITE to help ViteX obtain operational quota, users receive VX rewards.Allocation: 20% of daily released VXHow to participate: stake VITE with the beneficiary set to the ViteX smart contractStaking amount: the minimum amount of VITE that users can stake is 134 VITE. There is no maximum cap.Staking duration: Stakes can be retrieved after 3 days. There is no maximum number of days for staking VITE. There will be a retrieving period of 7 days, and stakes will not be counted towards staking as mining rewards during this period.Mining reward calculation : the amount of VX rewards will be calculated based on the proportion of VITE staked by a user’s account to the total amount of VITE staked that day.IV. Referring as MiningUser can request invitation codes to invite friends to join the ViteX platform.Inviter will be rewarded with 5% of all invitees’ trading as mining proceeds and 2.5% of their market making as mining proceeds.Invitees will enjoy 10% off platform trading fees, and receive an extra 2.5% of trading rewards and extra 1.25% of market-making rewards.How to participate: Spend 1,000 VITE to generate a referral code, of which 100% will be burnedNote: If you are a ViteX VIP (users who have staked 10,000 VITE to obtain a 50% reduction in trading fees) AND joined ViteX via a referral code, your 10% discount will be applied after the reduction.V. Listing as Mining (Operators Only)For each trading pair listed, the issuer’s VX reward is then calculated as if he/she executed a trade involving a transaction fee of 1,000 VITE.Operators can list trading pairs, customize transaction fees, and generate profits from users that choose to trade on their Zone.VX Distribution ScheduleThe total supply of VX will be 29,328,807.8 with no inflation. The total supply of VX will be fully distributed in two phases.Phase 1: Buffer phase that has ended on December 6, 2019. A fixed amount of 10,000 VX was released daily.Phase 2: Standard Phase. In this phase, all un-mined VX will be released according to below schedule:Sub-phase 1: Starting at 10,000 from December 7, 2019, daily release will increase for 90 days at a fixed rate until reaching 50,000 on March 6, 2020Sub-phase 2: Starting from March 7, 2020, annual release will decrease by half each year until fully distributed after 8 years.VX Mining AllocationAllocation of VX daily release by proportion:Trading, Referring and Listing: 60%BTC market: 15%ETH market: 15%VITE market: 15%USDT market: 15%Staking: 20%Market-making: 10%Vite team: 10%VX Holder DividendsAll fees collected by the ViteX platform will be collected into a shared dividend pool and distributed at a rate of 1% daily. For any given day, the total fees collected during that day will be fully distributed by the 100th day.To receive your dividends:• A minimum of 10 VX must be staked in the exchange account. Please note that VX held in a wallet or exchange account will not make you eligible for dividends;• Participant is entitled to receive dividends starting with the next distribution immediately after submission of staking request;• Staked VX will be released after the 7-day waiting period once retrieved. No dividend will be received during this waiting period.Users can enable automatic staking. Mined VX will be automatically staked once enabled, purchased VX is not subject to this function.Transaction FeesTransaction Fee FormulaFor all transactions on ViteX, incomplete orders do not incur any fees.Total Transaction Fee = Base Trading Fee + Operator Zone FeeUnlike other DEXes, ViteX does not charge fees for pending orders and withdrawals provided that users have the requisite amount of quota. Related documentation: What is quota.Base Trading Fee: 0.2%This trading fee will be applied to all trading pairs in the ViteX ecosystem. All the fees collected from this will be put into the shared dividend pool to be redistributed back to VX holders.Operator Zone Fee: 0–0.2%This is the fee that will be set by ViteX Operators for their respective Zones. Operators may set fees ranging from 0% to 0.2%.

Both parties will jointly explore payment solutions and develop infrastructure for blockchain interoperability. KardiaChain is in partnership with a top telecom company in Vietnam with 60 million users, and it aims to establish Vietnam’s first mobile payment gateway. Vite’s collaboration with KardiaChain will provide more opportunity to expand Vite’s crypto payment network in Vietnam and Southeast Asia.ViteX ExchangeOn April 30, ViteX released DEX API. Users can apply for API Keys on the ViteX website. The launch of the API will further expand the ViteX trading ecosystem, help attract quant traders, and improve liquidity for the exchange.On May 8, KardiaChain coin(KAI) was listed on ViteX via Vite Labs gateway. On May 9, KAI / ETH trading pair was opened, enabling market-making as mining.Users with more than 10 VX in the Vite app received an airdrop of 1,250,000 KAI. This is the first time we rewarded VX users with airdrops, and we received positive feedback. In the future, we plan to run similar campaigns, iterate on best practices for airdrop rules, and coordinate with projects to increase airdrop amounts. We hope these measures will continue to raise VX’s intrinsic value.Technology SeriesOn May 6, we published the technical article “The Design and Implementation of ViteX Contracts”, which briefly explained the smart contracts used within ViteX.Community AMAOn May 9th, KardiaChain ran an AMA in Vite telegram group and rewarded 150,000 KAI to the community.Vite Official WebsiteWe ran a community vote on the new design of The result will be published soon. Thanks all for participating!Vite MainnetOn May 27, Vite network will have the fourth hard fork named MARS. The main purpose of this hard fork is to upgrade the built-in contract of ViteX. Details: on ViteXAs of May 15, 16,740,658 VITE have been burned, accounting for 1.67% of total issuance.137,756,367 VITE are staked on ViteX exchange, accounting for 13.78% of total issuance.6,377,320 VX has been released, of which 5,957,905 VX is being staked for dividends.To-date, 49.5 BTC worth of dividends have been distributed. The pool of undistributed dividends stands at 30.3 BTC.System DevelopmentsVite WalletVite Wallet 3.6.0 (iOS and Android) has been formally released. This version re-writes the built-in ViteX exchange in native code so as to significantly optimize the trading experience. In addition, Vite Connect, which is relied upon when generating ViteX API Key, was also upgraded. Users can self-generate API Key on the ViteX website by scanning the QR code in Vite Wallet.After the 3.6.0 version was released, we received many valuable feedback from the community. The feedback has been well collected, and will be prioritized and incorporated in subsequent versions.On May 11, we released Vite Wallet 3.6.1 (iOS), solving the problem that some ERC20 token transfers may fail due to gas limit, as well as under certain circumstances the built-in ViteX page may be stuck.On May 14, we submitted Vite Wallet 3.6.1 (Android) to Google Play for review. This version fixes the occasional app stuck problem when switching addresses, and the problem that exchange-related message may wrongly appear on non-exchange pages.We also started the development of V3.7.0. In this version, we will continue to add new features to the exchange, and reduce the size of app package for faster download.Starting from V3.6.0, we changed the app name from Vite Wallet to Vite, meaning that the positioning of Vite wallet has changed from a single-purpose wallet to a full-stack wallet + exchange decentralized crypto asset management tool.ViteX ExchangeViteX API has been formally released. In the past two weeks, we have made additional optimizations, such as checking the minimum order amount and available balance to avoid invalid transactions, and standardizing error code and message returns.We are in the process of integrating ViteX API with CCXT. CCXT ( is an open-source cryptocurrency exchange API adapter library that currently supports 120 exchanges. Through CCXT, users can ignore the differences in API interfaces of different exchanges and simplify the development of trading bots. At present, there are many quantitative trading programs that use CCXT library to access different exchanges. After our integration, these existing programs will be directly accessible on ViteX.In addition, the upgrade of ViteX built-in contract is finished. A new hard fork has been scheduled on May 27, which includes optimizing order cancellation logic, unifying the logic of order flows by raw signatures and delegated orders, and merging order placements and cancellations from the same address into one queue to ensure deterministic matching result.Website UpgradeWe have completed the product design and visual design of the new The new version of Vite official website focuses on key information for facilitating new visitors to understand the full picture of Vite.In the visual design, we have selected 6 different design schemes. It’s completely up to our users to choose the final plan through community voting.ActivitiesVite COO Richard released a new episode on The Blockchain Debate Podcast.

Tech Series #3: The Design ...

ViteX is a built-in decentralized exchange on Vite. As an important component of the Vite ecosystem. ViteX consists of Vite’s built-in contract vDex and the off-chain service dexServer.vDex is designed to perform all of the exchange’s core functions on-chain, such as deposits, withdraws, listing trading pairs, and order matching. However, subsequent on-chain functions like mining of VX coins, fee dividends and operator management have been included as well. Needless to say, all these functions are implemented with high security and full transparency of rules in mind.The following is an introduction to several key points in the design and implementation of vDex.Storage DesignParticular to vDex’s implementation (as compared to that of other centralized exchanges) is the storage structure enhancements and performance of the chain itself. To maximize match efficiency, vDex has adopted multiple optimization strategies for read/write efficiency.Order IDThe method by which orders are stored determines the read/write efficiency, and ultimately determines the order-matching efficiency.At the lowest level, the Vite chain employs a LevelDB-like storage. It supports sequential traversal ordered by byte, which is consistent with vDex’s Taker-Maker matching rules. These rules do matching according to the price order of trading orders. vDex uses an order id format that complies with levelDB’s ordering mechanism, ensuring that Taker matching takes only one iteration to complete.The order structure is presented below:The order id is a 22-byte field composed of subfields as follows:marketId: a unique identifier for each trading pair. This is auto-incremented.side: 0 or 1 for Buy/Sell respectively. It is a 1-byte suffix to marketId. A Taker order will scan all pending Maker orders with the same prefix (marketId + side) during a matching process.price: a 10-byte long fixed-point number. The first 5 bytes correspond to the integer part, and the last 5 bytes to the fractional part. This can support a maximum length of 12-digit integer and 12 decimals. For a sell order, prices are stored normally from low to high, whereas in a buy order, the value is flipped to represent a reversed price order from high to low.timestamp: orders with the same price are sorted by timestamp.serialNo: for orders with the same price and timestamp, orders are sorted according to the sequence by which the orders were confirmed on the chain, ensuring a strict order.This 22-byte long order id serves as a key for levelDB traversal, thus providing efficient order traversal by price.Matching ProcessThe matching engine generates a new prefix from the combination of Taker’s marketId+!side. It uses this prefix to traverse through levelDB in ascending order, thus generating a list of all ranked orders in the market placed by Makers. A Taker’s order is matched when the following conditions are met: !taker.side && bytes.cmp(taker.price, maker.price) >= 0 || taker.side && bytes.cmp(taker.price, maker.price) <= 0. Any unmatched remainder is further processed until either the match fails or the transaction is completed. When a match fails, the taker’s order ID is sent to storage. The entire matching process adopts a simple and efficient way of reading/writing storage.Order Object CompressionTo improve storage efficiency, protocol-buffers are used to serialize the order object. If sufficient compression can be guaranteed, new fields may be added to the order structure to enhance backward compatibility.Storage can further be optimized by nulling the order ID’s four fields (marketId, side, price, and timestamp) prior to deserialization. During deserialization, only relevant fields are assigned.Storage Clean-upTo further reduce the occupation of on-chain storage, space is cleaned for completed matches and cancelled orders. Orders have a set timeout mechanism. Expired orders can be cancelled in batch without verification. To ensure all orders are accessible, cleared orders are persisted in dexServer service off the chain.Mining/Dividend Metrics Storage OptimizationvDex supports on-chain trade mining, stake mining, and handling of fee dividends. At the end of a day-by-day period, mining/dividend results are produced based on relevant metrics for the period.To avoid unnecessary impacts on normal transactions, mining and increase of period are made asynchronous. This requires that the state at the end of each period can be traced back via, in vDex’s implementation, snapshots. To minimize the number of snapshots, state of a new period is recorded only when there is a difference with that of a previous valid period, which minimizes storage duplication.Multi-Contractual CollaborationThe current version of vDex consists of two built-in contracts. dexFund undertakes operations such as deposits, withdraws, listing trading pairs, mining, dividends, etc. dexTrade completes the actual order placement, be it a match or a cancel.The design of two separate contracts facilitates system splitting and maintenance from an engineering perspective, and facilitates subsequent dexTrade sharding for higher throughput.Asset Correctness CheckCorrectness at code level is ensured through both unit testing and integration testing.vDex also verifies asset consistency in real time by comparing all the assets in built-in contract and the actual balance of the contract on the chain. If they are consistent, errors due to internal calculation and logic errors resulting in excessive asset issuance or loss can be ruled out.Asset check is equivalent to performing a full integration test on all the code of vDex’s contracts. This operation can be performed periodically during test phase or after formal deployment to verify the correctness of the contracts.vDex and dexServer CollaborationDuring the execution of the contracts, internal states are modified.
