It’s always great to hang out in this group. This group means a lot to the Aelf community. It is the first Aelf community and has been there through all the ups and downs in the world. I would like to start with wishing everyone is staying safe at home during the virus outbreak. It definitely has been a difficult time for all of us, but together we can pull through it.
We understand that the situation is quite striking to all of us. But I really believe that the solution to the virus outbreak is about more global coordination and collaboration.
All of you to be assured, our team in different places are all safe and working from home as normal.
The Aelf team in Beijing were among the early ones experiencing the virus outbreak. As everyone was on the way home for Lunar New Year holiday and then experienced a total city lock-down followed by a 40 days’ work from home policy. It was definitely not easy for them, but our team stayed strong, took necessary precautions and focused on work with the right morale. Mappo has recently published some tips on how to work from home effectively based on our experience. Do check it out. Despite not working in the office since February, we have achieved great progress, including launching Aelf 1.0 preview, which is an important milestone in technical delivery and also the roadmap to mainnet launch (which listed out the essential steps for the community to work together to launch a successful public network)
Let's first talk about Aelf v1.0 preview. It is the cornerstone of the mainnet launch. The product itself has all the features that the public network is needed. The codebase has been reviewed and tested rigorously by the team. And a few highlights of how the network would look like:
So how are we going to help the community launch the network:
First of all, we have launched the codes, documents about the economic system and governance model and technical features. With all the things available, you are able to understand what the system is about, as a token holder what's your benefit in the system, and being a node in the system plays a big role in the governance
Next, without yet electing the nodes, we will get all token holders to join the current Aelf network through a mapping event. That means as long as you have Aelf tokens, you will be able to get 1:1 test tokens on the public testnet. that gives you full access to all the features, and you will feel like you are already using the mainnet. You will get rewarded in making transactions, voting, etc.
Do try out the Aelf wallet and voting features, you will see how easy to transfer tokens cross-chain. and also how flexible the system allows people to make changes. For example, the community may want to adjust the block rewarding parameters or fees to use certain services on mainnet, they can initiate a discussion and then vote in the system and once voted through, it will be reflected on mainnet.
For people or organizations that want to play a bigger role in the system, we will do a dry run of node election. Take it as the real node election before mainnet launch. We will see who the active members of the community are and being trusted by the community. Among the nodes, we will form a network launch committee. The committee will be the crucial party to oversees and ensures the smooth launch of Aelf mainnet, instead of just relying on the Aelf team. This is our step towards decentralization.
The committee will agree on the actual launch process, final checking all the parameters in the system to be ready for launch and then decide when the criteria are met to launch the network. Once all that is decided. We will invite all interested nodes to apply for the election and let the community know what's their plan to grow the Aelf network. the network will initially be launched with a few nodes from the committee and gradually be replaced by the selected nodes (a bootstrap phase). Along the way, we will work with exchanges to conduct token swap (which we are also designing an innovative system to further enhance security and usability of Aelf tokens in exchanges)
Among this isolated and worrisome time, at least we all have something to look forward to: a successful launch of Aelf network! Once it is launched, we are excited to see a vibrant and technically superior network that is good for Dapps to run on top of it.
Doris Guo Q1: As a Blockchain start-up, what difficulties have you overcome when starting Aelf project? What motivates you to solve difficulties and achieve success today?
Zhuling Chen First, just like launching any start-up, its community and investors are usually regional. There is always some bias on if Asian projects are solid. It is really rare to have an Asian project to be supported by western funds and community from day 1. We were lucky to have overcome that obstacle. Having a global investor line-up from day 1. Having a global team from day 1 and also working with a global community from day 1. This benefited us to have an international perspective which is crucial in the blockchain industry.
Secondly, as a hardcore technology company, it is really hard to put in plain words what is our ambition. Our ambition is huge, achieving key innovations in multiple fronts of blockchain technology and organically combined them to serve real users for the future. Our marketing team has been working really hard to elaborate on what Aelf is. Now we have come to a point that the product is ready. Therefore, it is much easier for all of us to understand how solid Aelf is by trying out the network ourselves! That's exactly what the following events will be about - Try out all the exciting features of Aelf network before mainnet launch.
Doris Guo Q2: What critical problems do you see occurring in the blockchain industry nowadays? How does Aelf solve these problems?
Haobo Ma First, we need to distinguish the difference between BTC and ETH. One is Digital Cash and the other is the Smart Contract Platform. Aelf addresses most of the latter's problems. In short, it can be summarized as performance, end-user friendly, developer-friendly, network economy, and self-governance and upgrading. Each of these areas will probably take up a lot of space, and as a whole are the issues described in our two white papers. In short, Aelf is faster, end-users do not need to know the rules of the blockchain, developers can set up the development environment in 10 minutes, have a good economic model and can carry out proposal governance on the chain.
Doris Guo Q3: What is your long-term vision about the industry which Aelf is working at? Are you afraid someday there will be another project with more innovative technology can replace Aelf?
Haobo Ma Let's talk about where Aelf stands in the traditional Internet. It is essentially a cloud service provider, Aelf provides resources and infrastructure for developers to deploy their services, known as smart contracts. We eventually want Aelf to grow like AAA (Amazon, Azure, AliCloud). Because Aelf is a network that can be dynamically scaled, we can accept any new technology, some of the more advanced technologies we can put on a side chain.
Doris Guo Q4: Why did Aelf choose for cross-chain interaction?
Haobo Ma As I mentioned earlier, Aelf solves the Smart Contract Platform problem. However, there are other digital cash problems as well which we would need to use existing infrastructure such as Bitcoin's chain in order to interact with Bitcoin. There are a lot of infrastructures on Ethereum that we want to interact with. Multi-chain on Aelf network mainly is to isolate resources to improve network performance and network stability.
Doris Guo Q5: What difficulties do the Aelf team have now (I talk about COVID-19)? How does the Aelf team solve it? Have you changed the roadmap?
Haobo Ma There is no great impact. The teams in Singapore and Beijing are communicating with each other remotely on a regular basis. The only change is that most of us are now working from home which has no impact and in fact, it seems conducive to the acceptance of more community developers in the future to come. From the internal working schedule and development timeline, there is no great impact. We do not publish specific timeline as we do not want short term holders (traders) to create too much negative pressure on product development.
Doris Guo Q6: Aelf is an open-source blockchain, and there's the common problem of taking a substantial amount of time for the different participants to agree on strategic decisions. What types of governance models do you use in Aelf to address this issue???
Haobo Ma The issue is about public blockchain network, and who can decide the direction of the network. Our answer is long-term holders. For the short-term holders (traders), we refuse to allow them to participate in any discussion of the direction of Aelf because the short-term holders are likely to make a profit and sell quickly, which is essentially the same example of a person who cheats the President and then runs away for his personal gain. We defined a number of proposal processes, including the logic of the two-party system in the United States, and the participation in the referendum to ensure that the final proposal represents the majority. At the same time, we are looking for some legal solutions to avoid bifurcation, such as prohibiting exchanges from intervening in bifurcated new tokens. While we cannot limit a community, we should be able to find ways to limit a centralized organization. This restriction is akin to a ban on national secession.
Doris Guo Q7: How will Aelf empower Investors, Companies, Developers, Platform Users to deliver impactful solutions and bring value to people all over the world?
Haobo Ma We will learn from the operational experience of successful foundations such as the LINUX foundation and license some commercial companies to use Aelf solutions to solve business problems. At the same time, Aelf is an open-source product under the MIT License, and we accept any use that does not violate this open-source principle.
Zhuling Chen Let me add on to Haobo’s statement: to incentivize and empower the community, we are also exploring ways to let the community decide how to use the funds for Aelf (allocate to where it matters to our community) once mainnet is launched. This means you guys can decide what are the projects to be funded on Aelf, etc
Doris Guo Q8：When will the node campaign start? How will Aelf attract users to participate in nodes election?
Haobo Ma According to our published roadmap, the timeline can be dynamic, but I don't think it will be too long. The main idea is to let everyone understand what we envision Aelf to be like, and what are the rights and benefits of being a node in the future. We hope to find nodes that fully recognize the efforts of Aelf at the present stage and are willing to participate in the future development of Aelf. We will run a simulation of the node campaign on the testnet and set up a temporary mainnet launch committee. Please follow our official Twitter for more upcoming details!
Doris Guo Q9: Token swap form 2 is some kind of cross-chain transfer? It will be handled by a smart contract?
Haobo Ma It is handled by the smart contract, we define an asset cross-chain transfer protocol, but it may be opened after a snapshot.
Doris Guo Q10: Which Exchanges will support token swap? Do you have any plan to list Aelf in some big exchange like Binance, Houbi, Kucoin, .......?
Haobo Ma We are already in talks with some exchanges, there is still competition between exchanges, and many are still hoping to attract more users by getting access to mainnet token swap early.
Doris Guo Q11: Aside conversion of the current tokens to mainnet tokens, what other main features will be accomplished with the mainnet launch?
Haobo Ma We have a documentation file that has been published, which has listed some features: https://Aelf.io/gridcn/Aelf_public_testnet_and_supporting_features_introduction_en_v1.0.pdf
Doris Guo Q12: Do you have any plan to burn or buyback your coin?
Haobo Ma We have plans for the community to govern through DAO, we have no interest in short-term price incentive adjustment as we would prefer to drive the project to higher adoption. After mainnet starts operation, there will be a part of network revenue get destroyed automatically.
Doris Guo Q13: Often, as a newbie developer, I face difficulties on most blockchains. How easy and convenient is it for me on Aelf, and what programming language and tools are needed??
Haobo Ma We set up staging for DAPP developers on GitHub and configured CI. Develop a smart contract using C# with React Native on the front end. So, in fact, developers can fork the source code without setting up the environment locally, and you can conduct unit testing with the help of CI. You can also release the smart contract and generate the installation package of iOS and android online. https://github.com/AElfProject/Aelf-boilerplate
Doris Guo Q14: What is the progress of business development and what are some of your commercial partnerships? How will Aelf rapidly develop the number & performance of DAPP?
Haobo Ma First of all, the blockchain industry is still fairly small and users with ETH and EOS wallets are considered a very small group and its not effective to even promote within these groups. What we need to consider is how to enable users who have never been exposed to blockchain to use DAPP. The competitiveness of Aelf is to make it easier for Aelf developers to promote their DAPP to ordinary users, rather than to teach ordinary users a lot on blockchain knowledge. The average user doesn't like to hear about private keys, mnemonic, Gas Price, RAM, CPU, etc. Only until we solve such problems, companies that need to solve problems through blockchain will be more inclined to use Aelf in technology selection. Therefore, our main work is to explain the competitive advantages of Aelf, ETH and EOS to everyone. We have some business cooperation’s, but we also believe that simply through case-by-case business cooperation will not be able to gain adoption so quickly, therefore we still need to put our products to stay ahead of the next generation.
Doris Guo Q15: What other activities can encourage more people to be confident about Aelf?
Haobo Ma We are only going to state the truth by having those that have faith in us to stay and those that don't to leave. The development of Aelf is not driven by a single foundation, but by a steady stream of contributions from the community. In the future, we will also place the activities in the DAO for on-chain governance, and let the community make decisions by itself.
Kun Aguero As you know that in the present market situation many new coins or either dying or thriving for liquidity? How will you manage this liquidity problem?
Zhuling Chen Aelf started in 2017. we have gone through a few cycles in the market, still, remember the big down period in 2018-2019. Aelf is financially solid and the team has always been working hard. if you are referring to liquidity in exchanges, we are among the lucky ones that are listed in all major exchanges
Xinshu Dong Hello, great discussions! I would like to ask what are the criteria to join the committee for launching the mainnet? Would love to participate
Zhuling Chen Hi xinshu, great to see you here. The committee will be chosen among the nodes elected during the testnet dry run. Which means, it is really important to participate in the testnet dry run and also start to establish your reputation in the community so that people will elect you as a node. The detailed criteria will include what is your plan to help Aelf to grow, tech competency and reputation.
An Da What are Aelf’s achievements in 2019? Who had supported you to get those things?
Zhuling Chen To name a few, in 2019, Aelf is one of the most active projects on GitHub. This means Aelf is evolving and improving fast in this space and our team has the tech strength. In addition, we have also successfully listed on all major cloud service providers, such as AWS, Azure, Google. So large companies can easily launch Aelf side chains in their organization with minimum hassle.
John How does the voting for master nodes candidates occur? And why is the development of this system important for your project?
Zhuling Chen Voting is going to be pretty simple. All token holders can vote for the nodes they support on our block explorer.
Miha After mainnet lunch, how will you assure that transactional fees will stay low? We know what sometimes happens to fees on ETH blockchain.
Zhuling Chen First of all, due to the fact that is Aelf is scalability, this will reduce transaction fee. Secondly, all transaction fees will be voted by the nodes (which will be elected by you). So they will represent your interest
Bobbyfernandito Currently, as we see All projects are concerned with the speed and security. So, tell us here - what are the facilities Aelf provide to their user and investors?
Haobo Ma Security: we have an automated smart contract code audit. During contract deployment, production nodes and the community audit participation are required. On the other hand, we are also planning to provide a standardized model of centralized exchange access for 100% asset certification and emergency measures to deal with exchange attacks, which we will be released later. Speed: Aelf has been working on improving performance, which is transparent to users which they can also experience by themselves.
An Da What effect does Aelf token have on the Aelf ecosystem? Holding Aelf, what benefits will users receive?
Zhuling Chen Holding ELF enables you to use all the services on the Aelf network. ELF has a deflating system where the total amount will reduce as the network grows. token holders can also vote for the nodes to run the network and also vote for big decisions in the network. part of the fees in the system will also be distributed to token holders via a smart contract
ahihi132 Which companies do you view them as potential partners and that they are somewhat also beneficial for both the user base and Aelf itself?
Zhuling Chen Great question, if I could write a wish list, that will be: let medium-sized financial institutions to use Aelf to challenge the big boys. Let telecommunication companies use Aelf for micro-payment and other innovative business models. We also would like to try out a few public sector projects, which blockchain will is still more transparency and trust
Misun Q1: Which programming languages are you using in your project? And why? Q2-What are another big MILESTONES you have planned for 2020 roadmap and how are they supposed to benefit your costumers? Will it be an exciting year?
Haobo Ma For Q1: We mainly use C# for development, I personally like it. Performance is good, development environment IDEs are strong, and C# creators are influential in the industry. We believe in the right thing, though it may take a while to develop. The smart contract will then add support for multiple languages, such as WebAssembly, depending on the needs of the community. Now it seems that C# is enough.
Hambi crypto Which platforms are your competitors? How will you soar above them, and what better things do you offer than them? So, What’s your outlook on the future of cryptocurrencies in this year and next few years?
Haobo Ma As I have already mentioned this before, Eth and Eos. We provide better performance, cross-chain support (already implemented), end-users do not need to know the details of the blockchain, developer’s payment models and so on.
Floris-Jan What plans is Aelf making to prevent centralized exchange to take over the DPoS algorithm like what happened to Steem? Are we talking about blacklisting exchange wallets, or having the foundation say "No", or putting all trust in the community?
Zhuling Chen Great question, Floris. I’m not going to give away all the details of what Haobo has proposed to work on this, but in a nutshell, in Aelf system, exchange wallets will not be allowed to vote, but only the sub-wallets for each individual can vote. This will also help exchanges to prevent hacking and theft in the future
Alex What your plans in place for global expansion, are Aelf wallet focusing on the only market at this time? Or focus on building and developing or getting customers and users, or partnerships? Can you explain this?
Haobo Ma Our core focus will be through the developers to promote, developers will help Aelf to attract more users. So our product has to be attractive to developers. Just like AWS, they only focus on getting their service right, their developers will think about how to promote it. We don't want to burden them in their promotion process.
Ellkay What do you think are the major threats and barriers that could face the development and adoption of Aelf?
Haobo Ma If I'm a DAPP developer and I need to promote my APP to people who don't recognize blockchain, then I'd like to choose a platform that doesn't have to explain a lot of blockchain details to the end-user, so they can use it easily. We've provided some options in the Boilerplate that allow you to log-in simply via QR code + Password, and our recommended Dapp is an independent wallet and a separate iOS/Android application.
ahihi132 Give me some important reasons why we need to hold Aelf token where in fact hundreds of projects failed and it went to bankruptcy or even developers run when they collect millions/billions of funds?
Haobo Ma First of all, we will not give any suggestions as we only describe the fact that the long-term token holder will be able to govern the Aelf network, get Aelf mining reward and Aelf network profit. At the same time, Aelf network is a deflation model, Aelf network received transaction fees, profit dividends will immediately destroy 10% etc. All investments are risky, and we don't judge the behaviour of other developers. There are so many things in this world that cannot be understood and unfair. It is important to do our job well. I cannot explain these things.
胖 见愁 I remember that boss Ma mentioned to only find those truly innovative applications and enterprises with blockchain, how to find and win partners in these aspects?
Haobo Ma When Linus was developing Linux, I did not think he would find a lot of collaboration when the code was not good. The response we can give is that we already have a lot of interest in cooperation, including what we have announced, what we have not announced, etc.
胖 见愁 How interested are cloud computing providers in participating nodes?
Haobo Ma The vast majority of our nodes should be using cloud services, and as long as a large number of our 17 nodes and other candidate nodes are based on cloud services, our network robustness is determined by these cloud computing providers. Of course, in the expansion, we can also use cloud computing services.
claimAll will not work for most users. When you get to the claim step, please use the following tutorial: https://steemit.com/eos/@koyn/minimizing-the-cost-of-gas-when-claiming-eos-using-myetherwallet
REMEMBER YOU ONLY NEED TO REGISTER YOUR TOKENS IF YOU BOUGHT THEM ON AN EXCHANGE. YOU DON'T NEED TO CLAIM THEM.
So PLEASE REGISTER your Ethereum address NOW, don't forget about it, or plan on doing it some time in the near future.
- Go to the EOS website https://eos.io
- Scroll down and select "GET EOS"
- Tick all the required boxes and click "Continue"
- Scroll down and click "Register"
- Select Metamask, MyEtherWallet, or Ethereum Wallet
- Follow the guide.
- Remember that the reason you need to register your Ethereum ERC-20 address is to include your EOS tokens in order for the balance of your EOS Tokens to be included in the Snapshot if a Snapshot is created, you must register your Ethereum address with an EOS public key. The EOS snapshot will take place prior to the 1 June 2018. After this point your ERC-20 EOS tokens will be frozen. And you will be issued EOS tokens on the EOS blockchain.
“EOS.IO software utilizes the only known decentralized consensus algorithm proven capable of meeting the performance requirements of applications on the blockchain, Delegated Proof of Stake (DPOS). Under this algorithm, those who hold tokens on a blockchain adopting the EOS.IO software may select block producers through a continuous approval voting system. Anyone may choose to participate in block production and will be given an opportunity to produce blocks, provided they can persuade token holders to vote for them.
The EOS.IO software enables blocks to be produced exactly every 0.5 second and exactly one producer is authorized to produce a block at any given point in time. If the block is not produced at the scheduled time, then the block for that time slot is skipped. When one or more blocks are skipped, there is a 0.5 or more second gap in the blockchain.
Using the EOS.IO software, blocks are produced in rounds of 126 (6 blocks each, times 21 producers). At the start of each round 21 unique block producers are chosen by preference of votes cast by token holders. The selected producers are scheduled in an order agreed upon by 15 or more producers.
Byzantine Fault Tolerance is added to traditional DPOS by allowing all producers to sign all blocks so long as no producer signs two blocks with the same timestamp or the same block height. Once 15 producers have signed a block the block is deemed irreversible. Any byzantine producer would have to generate cryptographic evidence of their treason by signing two blocks with the same timestamp or blockheight. Under this model a irreversible consensus should be reachable within 1 second."
"The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform."
"In sum, Defendants capitalized on the recent enthusiasm for blockchain technology and cryptocurrencies to raise funds through the ICO, illegally sold unqualified and unregistered securities, used a Swiss-based entity in an unsuccessful attempt to evade U.S. securities laws, and are now admittedly engaged in the conversion, selling, and possible dissipation of the proceeds that they collected from the Class through their unregistered offering."To ensure EOS tokens are not classed as a unregistered security block.one has made it clear that they are creating the EOS software only and won’t launching a public blockchain themselves. This task is left down to the community, or more precisely, the Block Producers (BPs). The following disclaimer is seen after posts from block.one:
"block.one is a software company and is producing the EOS.IO software as free, open source software. This software may enable those who deploy it to launch a blockchain or decentralized applications with the features described above. block.one will not be launching a public blockchain based on the EOS.IO software. It will be the sole responsibility of third parties and the community and those who wish to become block producers to implement the features and/or provide the services described above as they see fit. block.one does not guarantee that anyone will implement such features or provide such services or that the EOS.IO software will be adopted and deployed in any way.”It is expected that many blockchains using eos.io software will emerge. To ensure DAPPs are created on an ecosystem that aligns with the interests of block.one a $1bn fund will be has been created to incentivise projects to use this blockchain.
“A lot of token distributions only allow a small amount of people to participate. The EOS Token distribution structure was created to provide a sufficient period of time for people to participate if they so choose, as well as give people the opportunity to see the development of the EOS.IO Software prior to making a decision to purchase EOS Tokens.”
“block.one intends to engage an independent third party auditor who will release an independent audit report providing further assurances that block.one has not purchased EOS Tokens during the EOS Token distribution period or traded EOS Tokens (including using proceeds from the EOS Token distribution for these purposes). This report will be made available to the public on the eos.io website.”
"DDoS'ing a block producing is not as simple as knowing their IP address and hitting "go". We have distributed systems engineers in each of our candidate groups that have worked to defend DDoS systems in their careers. Infrastructure can be built in a way to minimize the exposure of the Block Producing node itself and to prevent a DDoS attack. We haven't published our full architecture yet but let's take a look at fellow candidate EOSphere to see what we mean. As for the launch of the network, we are assuming there will be attacks on the network as we launch. It is being built into the network launch plans. I will reach out to our engineers to get a more detailed answer for you. What also must be considered is that there will be 121 total producing and non-producing nodes on the network. To DDoS all 121 which are located all around the world with different security configurations at the exact same time would be a monumental achievement."
"The only way to maintain the integrity of a community is for the community to have control over its own composition. This means that open-entry systems built around anonymous participation will have no means expelling bad actors and will eventually succumb to profit-driven corruption. You cannot use stake as a proxy for goodness whether that stake is held in a bond or a shareholder’s vote. Goodness is subjective and it is up to each community to define what values they hold as good and to actively expel people they hold has bad.
The community I want to participate in will expel the rent-seeking vote-buyers and reward those who use their elected broadcasting power for the benefit of all community members rather than special interest groups (such as vote-buyers). I have faith that such a community will be far more competitive in a market competition for mindshare than one that elects vote buyers."
George Cao :Let’s welcome lambda team . Xiaoyang and Lucysubmitted by BitMax_Support to BitMax [link] [comments]
Lambda: Hello friends from BitMax ~~ I am Lucy Wang, Co-founder and CMO of Lambda. I am very happy to e-meet with you here and thx for George's invitation. I on behalf of Lambda wish all of you a merry Christmas and prosperous new year in 2019
George Cao: Great. I am a bit surprised to see a big volume day yesterday Christmas. Seems our users didn’t take a break even on holidays :)
Lambda: I'd like to take this opportunity to introduce myself first, I have over 14 years of progressive career development with global leading enterprise software / service organizations as well as VC-backed start-up ventures, including HP, Oracle, and SAP. Before Lambda I was CMO/GM at two enterprise SaaS start ups in China backed by top VCs.
And my partner Mr. He Xiaoyang, who is the founder of Lambda, he is a well-known expert in infrastructure and open source software in China. Prior to Lambda, he was the co-founder of OneAPM, a fast-growing infrastructure software focusing on ITOM (IT operation management) in China. OneAPM is known as the “New Relic or AppDynamics of China” and the company has received strong VC backing from Matrix Partners, Chengwei Capital, and Qiming Venture. Prior to his entrepreneur experiences, Mr. HE worked at BEA as a R&D software engineer. In addition, Mr. HE is also a blogger with strong following in China and some of his articles have been published by major media such as Forbes China, 36Kr, Sina, etc.
Lambda idea was born at the end of year 2017 and the product development started from the beginning of 2018. Now let me talk about Lambda idea and what we do
Lambda, is the leading decentralized infrastructure project providing secure, reliable, and infinitely scalable decentralized storage network that enables data storage, data integrity check, security verification, and marketplace for storage-related services on the Lambda Chain Consensus Network.
In recent years, there have been frequent data leakage problems in major Internet platforms at home and abroad, and even business giants such as Facebook and Marriott have not been spared. Returning the value of data to data owners is an inevitable trend in line with human pursuit of freedom. The block-chain technology with P2P features provides an opportunity for this, and this area will be highly valued by the industry in the next few years. Lambda is the only provider of block-chain storage infrastructure projects in China. It is sometimes referred as “File-coin of China”or “File-coin 2.0”.our vision is to return the value of data to the data owner, with this vision in mind, our mission is to promote the decentralization of the Internet, with the goal of creating a storage infrastructure for the next generation of block-chain.
After the Lambda project launch in early 2018, it has received strong support by well-known strategic and financial investors including Bitmain, Viking Capital, FBG Capital, Bluehills, Zhen Fund, FunCity Capital, Ceyuan Digital Fund, BlockVC, INBlockChain, DATA Foundation, Bitcoin World, Reflextion Capital, etc. To date, Lambda has received investment funding in excess of $10M.
n all the existing decentralized storage projects that are aiming to give a solution to this problem worldwide, Lambda is the first ever to announce its LPDP ( Lambda Provable Data Possession )
George Cao: I see we share several investors in common, So 2019 q1-q2 will be a big milestone for lambda
Lambda: Provable Data Possession (PDP) and Proofs of Retrievability (POR) are critical to efficient decentralized data storage and its implementation, which is the essential difference between centralized network projects and real decentralized storage. Prior to Inter-planetary
File System (IPFS), Lambda launched its minimum viable product (MVP) of core functions in the third quarter of 2018, and has been continuously upgrading and optimizing this in block-chains in a multi-role environment.
File-coin is our main competitor, here is a chart shows the progress comparison FYI
For those who have interest to know more about Lambda's technical innovations, they can be find in our keep updating FAQ document posted on Medium, and I copied her FYI
1.Innovatively designed the Validator role which provides verification service for storage proof and the Validator replaces storage miner as the full-time storage proof result verifier, this greatly improves the performance of the storage and retrieval system.
2.In response to the limitations of the PDP algorithm, Lambda innovatively created a consensus network on the block-chain and used the validators role to replace the "TPA" in the PDP algorithm.
3.Innovatively modified the PDP algorithm from synchronous to asynchronous communication, which greatly reduces the communication traffic for Challenge in the system. Use of chain data as a random seed for storage miners to issue Challenge themselves addresses the randomness of TPA challenges.
4.Innovatively upgraded the PDP algorithm from periodic verification to a verification set generated by the miners to submit the verification result at one time, and fully realize the Proof-Of-Space-Time verification.
on top of all the technical, Lambda creates a consensus network where data can be stored, storage space can be rented on the basis of a marketplace built on block-chain.
In the Marketplace, the transaction process is: storage miners pledge hard disk sectors to the consensus network, and place orders and sell their own storage space in the Marketplace; storage users initiate purchase requests, complete the matching of storage requests through the Marketplace, and store data in the space of the storage miners.
Different from other block-chain applications, Lambda is a storage mining project, we have miners mine on Lambda network. Earn LAMB tokens by contributing on the network, and users who have data storing requirements pay Lamb tokens to purchase services accordingly.
The price of Lamb token not only rely on the exchanges but also supported by our miners who are doing works on the network.
There are four roles in the Lambda mining network: storage miners (providers of storage space), verification miners (ensuring the integrity and security of data and packaging transactions), retrieval miners (providing download bandwidth), and users (storage buyers). 1024 verification miners promoted from storage miners constitute the Lambda-chain consensus network. So you will see three types of miners serve our users from all over the world.
The key milestones we are looking at is the launch of test-net, where miners can start mining and earn testing Lamb tokens, the date will be around end of Jan. 2019 and main network will go live in Q2, 2019, most likely in Apr.
Regarding our partnership, In the academic field, we have established a strategic partnership with Beijing Institute of Technology (BIT), which is well known in China for its engineering and computer science research programs, to conduct research into centralized storage.
In the commercial field, Lambda has established a strategic collaboration with IOST, a well-known public blockchain project, and Perlin, a super computing platform, and started to conduct pilot projects for decentralized application (DAPP) companies such as DATA and BCV. Lambda also has close ties to many leading Internet data centers (IDCs) in China. They join the Lambda network as miners and take advantage of their surplus server capacity to engage in the Lambda network ecology.
Q: Will the rest of the code be open sourced? If so when ?
Lambda: we have released the codes of core function module, the test net codes will be released gradually in Jan. pls stay tuned with our official github
Q: What can Lamb tokens be used for?
Lambda: Lambs are tokens in the Lambda ecosystem, which are mainly used in the following scenarios:
A. Users of services in the Lambda ecosystem have to pay with Lambda tokens.
B. Providers of storage services in the system have to pledge a certain number of tokens.
C. Verification nodes in the system have to pledge a certain number of tokens.
D. Verification nodes can obtain a certain number of tokens as accounting rewards.
E. Storage nodes get a certain number of tokens based on their storage capacity and their service level agreements (SLAs).
F. Other roles in the Lambda ecosystem can also obtain a certain number of tokens based on their contributions.
Q: What more incentives does miner gets to mine or rent storage on Lambda?
Lambda: every miner stars from storage miner on Lambda network, they get paid by providing storage space, when their business getting bigger, system will select the top 1024 storage miners and promote them to validator, who will get block generation rewards from system.
Q: how are the 1024 miners selected? Doesn't this become more centralised?
Lambda: we did a survey to the Chinese miners, they mainly fall into two groups, either are waiting FileCoin to go live with purchased mining machine idle at home or they are doing hard drive or graphic cards mining, which has a high requirement to the hardware standard. To mine on Lambda, you need a mining machine ( computer ) that has big storage space ( because the bigger the higher probability you'll be promoted to be a validator ) and the connection to the internet
Q: How much is initial supply?
Lambda: Lambda did two rounds of fund raising, private investors have a lock up terms of 2+4+4 meaning the first 20% of tokens will only be released 2 months listing on exchange. so on the day one listing till 2 months there will be only around 0.5% initial circulation, and after 2 months, 5% in total. in addition to that, as we are recruiting miners to join our network, actually ppl have been in a situation where they can't wait to mine on our testnet. with the mining mechanism we have, miners need to buy Lamb token to get their mining work started, because a certain amount of pledge need to be made
Q: What partnership will lambda and bitmax have in the future?
Lambda: We value the way BitMax doing things and care about projects, we feel like we found the right exchange to be listed, in particular an initial listing. we will work with BitMax and do some joint campaigns to boost the community
George: We have great chemistry with lambda team.
Q: And are you still primary list in there, I heard the list was delay? Is it related to Huobi?
Lambda: you are right, it is related to Huobi, but one thing you can be assured of is that our initial listing on BitMax wont change, but most likely a joint listing with Huobi.
Q: what about the time of primary list?
Lambda: we will primarily list very soon, we are targeting end of this week, now we are in the middle of some technical integration with Huobi
George: We can assure everyone that our team will do our best to protect our investors and serve our listing projects. The promise does not change whether or not if we co-list with huobi.
Q: We get reward to mine ? Any incentive? For testnet
Lambda: Yes, you have two ways obtain Lamb tokens, buy from exchange and earn more from mining, but firstly you have to buy Lamb on BitMax haha. Are you asking the reward from testnet by mining on it? yes, you will get test Lamb token, and they can be redeemed to Lamb token with a ratio that will be specified shortly. on Lambda official website www.lambda.im, we have whitepaper, besides that we also have economic whitepaper to explain how the lambda economic system runs, on Dec. 28 we will launch our yellow paper where we will demonstrate the detailed technical realization and all the parameter setting for mining on Lambda
Q: What are the implications if a miners rig goes offline or they decide to stop?
Lambda: If miners rig goes off, they will not get the reward from the corresponding generated block, if they do cheating there will be punishment from the system, and if they decide to quit, the pledge will be returned
Q: Lambda planning to have own FS?
Lambda: Yes, FS and consensus network is separate. validators and marketplace are on the consensus network, while Files are in the File System.
Q: Is Lambda GDPR friendly?
Lambda: yes, we are
Q: Hi can u explain what’s the requirements of decentralized data . Do You think big companies will like to use lambda services .... or it’s for medium level enterprises as big companies will go for their in house system with their reliable nodes ...
Lambda: this is a good question, from I seeing it, ppl call out the protection of privacy, it is a trend and it takes steps. Lambda has two big groups of prospects users, one is DAPPs, another is the general industries such as big data, AI, IoT, Games, Financial, etc, as long as they need massive data storage demand, Lambda has the opportunity, data storage is expensive, especially when we are talking about big data, a lot of companies will value the cost in this area very much. currently we have lighthouse customer like DATA, BCV, VVshare, in the very near future, a game that is developed by Lambda team will also go live on Lambda network. from the BD perspective, Lambda will create a satellite network ( you can take it as channel network ) to bring us customers, we have a few reaching out to us already
Q: Why suddenly launched on Huobi
George Cao: I believe lambda team has its own consideration. Projects esp in bear market are facing pressures from different parties. Investors users exchanges. Not everything is under projects control. What we can do as an exchange is to stand by our partners and fully support them down the road
Lambda: thx for the answer
Q: I think you have made a great choice working with bitmax. Bitmax have really helped push new
coins and their site in general with good PR, marketing and reward/airdrop promotions
Lambda: strongly agree with you
Q: GDPR has taken over the EU and the UK so that is very important
Lambda: you are right, so we see to be GDPR friendly, which is one of our differentiator from FileCoin
Q: Being GDPR friendly , European market is a go for lambda
Lambda: I have this plan to develop European market by having a Raspberry program, it is still in planning.
George Cao: Let’s take a last question and move to lambda community:) And as usual we will pick 3 best questions. We will send out 1000 800 and 500 btmx. @lambda do you want to pick 3 questions ?
Q: Recent partnerships are interesting , can you tell us about coming q1 2019 both in terms of technical and marketing developments ?
Lambda: from Marketing side, we are focusing on Chinese miners community and potential European market ( like I said still in construction ) Korean market is another, and US market to go along our compliance path, Lambda has been strictly abide by the regulations. from technical side, the most important task we are targeting is the main network launch as planned
George Cao: Thanks everyone for your time. It’s a great ama as usual. We do have the best community. We will pick 3 winners and we will announce here after we finish ama in lambda community
Lambda: thank you all for your time to participate the AMA, I had a great time with you, see you friends and have a nice day.
George Cao: Hello everyone, Merry Christmas:)
Lambda: Hello Lambdos. Today we have George, the founder of BitMax to join us for the AMA. Let's give him a warm welcome to do a introduction of BitMax
George Cao: I am George Cao, founder of bitmax. I am happy to take the opportunity to talk to everyone here. Thanks to the lambda team. Let me start with a brief introduction about us.
Bitmax.io (btmx.io) is an exchange founded by a group of Wall Street veterans. Unlike most projects, we are kinda of old :) core team are in their 30ish - 50ish. The 10 founding member have combined of 150 years of Wall st experience. I have 10+ yrs of high frequency trading experience therefore I know the trading system well. That’s why our match engine can handle 400k tps per second vs huobi 1000 tps. We want to build an exchange that is transparent, robust, and efficient. While our system is the best in class, we offer the lowest trading fees. We believe the current high commission will not sustain and we will see consolidating of the exchanges with better depth and liquidity and lower commission. We are happy to partner with lambda, one of the best projects in 2018. We are committed to serve the project and the community. Alright, I am ready to take questions. Anything you can ask, as tough as you want :)
Q: Haha nice platform.
George Cao: Thanks. We are young as a platform but we are working to deliver the best
Q: I see reverse mining is new , I used many other mining exchange but all have normal mining . How does reverse mining works?
George Cao: Reverse mining is an innovative approach that helps the exchange and the project in several ways. 1) the concept of reverse mining is by providing liquidity to the exchange, you get a rebate and deduct out tokens from your account of the same valued. You can think of a otc sell our. 2) the benefit is it removes lots of sell pressure from the secondary market. And provides a strong support for the token price. 3) it introduces lots of liquidity to the exchange and benefits all traders
Q: The BTMX used in reverse mining are locked forever?
George Cao: Yes so the total number of tokens are always reducing your
Q: I've really been enjoying using the bitmax exchange so far especially with the low fees and data usage rewards. Does the exchange plan to bring in a shorting function in the near future?
George Cao: Yes we will have margin and futures trading
Q: It was supposed to December right ?
George Cao: We postponed our margin to Jan. The reason is we want to be more careful on protecting margin call protections.
Q: Margin trading and futures is important for BTMX price to drive up
George Cao: Totally agree
Q: Does BitMax have any activities on New Year's Day?
George: We do have multiple promotional events. Including but not limited to airdrops. Please visit our website and stay tuned
Q: I saw the whitepaper of bitmax, can you talk more about your dividends the formula is really hard for me ?
George Cao: Sure 80% of our commission goes to our fee pool. 1/180 of the total pool will be distributed daily. As long as you are a token holder, the current rate we pay is over 100% annually
Q: Oh I see, so the dividends will be smooth, great idea.
George Cao: Yes unlike other mining exchanges have huge volatility on div we smooth our curve
Q: I've also heard there is a mobile app in the works, is this likely to be released in the near future?
George Cao: Almost done. Beta version is in testing
Q: What about the north American, will it be available in the future?
George Cao: We more cleared our legal path for fiat trading in us. Q1 2019 we will launch in the us
Q: Great news I think this will bring a big volume.
George Cao: Yes agree. Our team is excited as well
Q: With promotional Airdrops that require a certain amount of the BTMX token to be held such as The lamb one that has taken place on the exchange this week. Are tokens that are locked for data usage or in cards taken into account when balance screenshots are taken?
George Cao: Yes we will take that into account
Q: When will be the private sale tokens be released ?
George Cao: As soon as we mined 90m we will start to release
Q: So let me get this right .. you give us FREE BTC and ltc and even Lambda EVERYDAY if we hold BTMX and agree to share our data
George Cao: Free usdt btc eth
Q: Wow. In a bear market, Free btc is the best thing ever
George Cao: We share revenue with our users, 90% is usdt. Not sure if you like it:)
Q: also consider adding coins like ADA and few from top 30. People need more coins
George Cao: We are adding stellar and zcash soon
Q: I heard they are insured Unless we give password to someone hehe
George Cao: Yes we are using custodian service
Q: George are our funds SAFU with you? Exchange insurance? I would say it is With the industry giants backing this exchange
George Cao: Sequoia matrix bitmain fbg dhvc are our equity investors
Q: What’s to stop People dumping BTMX token after free btc Or stop capital investor dumping on retailer
George Cao: They get it every day. Why would they dump? All equity investors can not sell on secondary market. They can only to reverse mining
Q: Will margin allow reverse mining instead of normal mining?
George Cao: Not initially
Q: People do irrational things when btc moves Or whales dumping, I heard there was a lock up token or something. To stop this
George Cao: We required lock our tokens to get rewards. You can request to unlock at anytime but it takes 24 hours to process
Q: Binance is developing DEX any plans for BitMax ?
George Cao: Not anytime soon we have a looong to do:)
Q: It's good you have dex in mind , with improved scalability in future maybe bitmax can build good dex
George Cao: Agree
Q: Retail investors are important , George knows it haha
George Cao: We care most of retails
Q: It would help if they also burned or locked tokens up
George Cao: Yes we permanently locked
Q: Seems you have everything thought of.. but how about moving to Malta?
George Cao: We priority US. Once us is clear pretty much everywhere is clear
Q: Doesn’t any exchange cover US right now?
George Cao: Coinbase but they have 0 international coverage and 0 client service
Q: What sort of systems are in place for abnormal/suspicious activity on the exchange?
George Cao: We prohibit self trading. For unusual trading behavior we ban the account and as for explain in the first violation. For continued violations we permanently ban the account
Q: can we get a glimpse of mobile application ?
George Cao: There is a beta version you can use but we are keep improving
Q: What are the precautions taken to prevent wash trading ?
George Cao: We have pre trade and post trade checksums. E.g we don’t just scan one account. We check or related account
Q: Will market orders and stop-loss orders be available in the future?
George Cao: Yes we are working on it
Q: what do you think of lambda project and community
George Cao: Lambda is definitely one of the best projects this year. We have been working with lambda for months and have lots of respect ion for the team. Community is also great very well organized. I didn’t talk much but I joined lambda tele group for a while. Great interaction
Q: So the trading starts at 8 pm ETC?
George Cao: It’s postponed. Please stay tuned for announcements
Lambda: We will make announcement giving out time and new date.
Q: when please? It's also more professional to be able to give dates and respect them
Lambda Cao: we are working hard and aiming the date of Dec. 29, pls stay tuned, thank you
George: Unfortunately bitmax and lambda don’t have 100% control of the date and time. Huobi is holding the ball
Lambda: The listing dates have been postponed and we don't want to give out a random date. I request you to have patience and wait for official announcement
Lambda: we will try everything to protect retails interest
Q: Can’t let houbi just arrive late to the party?
Lambda: in the long run we may need Huobi to help us better protect us all
George Cao: We trust lambda team can make the best decision for all investors
Q: Have you been busy with listing recently? Anything else？
George Cao: We have been working 24 hours a day including Chris eve :) Listing and app and margin and lots of new improvements
Q: Why would we need huobi with bitmax on our side.
George Cao: Trust me we are as upset. However as an exchange our mission is to serve projects and investors. Please join us in fully supporting any decision lambda team made. We have 100% confidence in lambda
Q: Are you familiar with the REKTbot and SYSTEM OVERLOAD problems at bitmex
George Cao: Yes but still bitmex is the best place to trade future compare with okex
Q: Slap that Hayes fool when bitmax start margin and futures..
George Cao: Haha i don’t want to declare war with them. Let’s be a bit patient :)
Q: Could bitmax handle That volume and not system overload
George Cao: We are 100% confident
George Cao: Alright i have to run for another meeting. It’s been a great ama. Thanks everyone. For any trading related questions please contact our client support. We promise to get in touch in 5 mins 7/24. Thank you all!
Lambda: thank you for participation, have a nice day!

“What is unique about us is that we have actually put theory into practice.”https://preview.redd.it/n6lo2xcmtn621.png?width=800&format=png&auto=webp&s=281acce4b45eed8acf0c52b201d01cb6f0d13507
Wanchain’s Vice President of Business Development, Lini, sat down with blockchain media organization Neutrino for an AMA covering a wide range of topics concerning Wanchain’s development.
The following is an English translation of the original Chinese AMA which was held on December 13th, 2018:
Neutrino: Could you please first share with us a little basic background, what are the basic concepts behind cross chain technology? What are the core problems which are solved with cross-chain? In your opinion, what is the biggest challenge of implementing cross chain to achieve value transfer between different chains?
Lini: Actually, this question is quite big. Let me break it down into three smaller parts:
In China, we like to use the word “cross-chain”, the term “interoperability” is used more frequently in foreign countries. Interoperability is also one of the important technologies identified by Vitalik for the development of a future blockchain ecosystem mentioned in the Ethereum white paper. So cross-chain is basically the concept of interoperability between chains.
In essence, blockchain is a distributed bookkeeping technique, also known as distributed ledger technology. Tokens are the core units of account on each chain, there currently exist many different chains, each with their own token. Of especial importance is the way in which each ledger uses tokens to interact with each other for the purpose of clearing settlements.
Cross chain technology is one of the foundational technological infrastructures that is necessary for the large scale application of blockchain technology.
Neutrino: As we all know, there are many different kinds of cross-chain technologies. Please give us a brief introduction to several popular cross-chain technologies on the market, and the characteristics of each of these technologies。
Lini: Before answering this question, it is very important to share two important concepts with our friends: heterogeneity and homogeneity, and centralization and decentralization.
These two points are especially important for understanding various cross-chain technologies, because there are many different technologies and terminologies, and these are some of the foundational concepts needed for understanding them.
There are also two core challenges which must be overcome to implement cross-chain:
Combining the above two points, we look at the exploration of some solutions in the industry and the design concepts of other cross-chain projects.
First I’d like to discuss the Relay solution.
However the Relay solution must consume a relatively large amount of gas to read the BTC header. Another downside is that, as we all know, Bitcoin’s blocks are relatively slow, so the time to wait for verification will be long, it usually takes about 10 minutes to wait for one block to confirm, and the best practice is to wait for 6 blocks.
The next concept is the idea of Sidechains.
This solution is good, but not all chains contain SPV, a simple verification method. Therefore, there are certain drawbacks. Of course, this two way peg way solves challenge beta very well, that is, the atomicity of the transaction.
These two technical concepts have already been incorporated into a number of existing cross chain projects. Let’s take a look at two of the most influential of these.
The first is Polkadot.
This is just a summary based on Polkadot’s whitepaper and most recent developments. The theoretical design is very good and can solve challenges alpha and beta. Last week, Neutrino organized a meetup with Polkadot, which we attended. In his talk, Gavin’s focus was on governance, he didn’t get into too much technical detail, but Gavin shared some very interesting ideas about chain governance mechanisms! The specific technical details of Polkadot may have to wait until after their main net is online before it can be analyzed.
Next is Cosmos.
Cosmos is a star project who’s basic concept is similar to Polkadot. Cosmos’s approach is based on using a central hub. Both projects both take into account the issue of heterogeneous cross-chain transactions, and both have also taken into account how to solve challenges alpha and beta.
To sum up, each research and project team has done a lot of exploration on the best methods for implementing cross-chain technology, but many are still in the theoretical design stage. Unfortunately, since the main net has not launched yet, it is not possible to have a more detailed understanding of each project’s implementation. A blockchain’s development can be divided into two parts: theoretical design, and engineering implementation. Therefore, we can only wait until after the launch of each project’s main network, and then analyze it in more detail.
Neutrino: As mentioned in the white paper, Wanchain is a general ledger based on Ethereum, with the goal of building a distributed digital asset financial infrastructure. There are a few questions related to this. How do you solve Ethereum’s scaling problem? How does it compare with Ripple, which is aiming to be the standard trading protocol that is common to all major banks around the world? As a basic potential fundamental financial infrastructure, what makes Wanchain stand out?
Lini: This question is actually composed of two small questions. Let me answer the first one first.
The TPS of Ethereum is not high at this stage, which is limited by various factors such as the POW consensus mechanism. However, this point also in part is due to the characteristics of Ethereum’s very distributed and decentralized features. Therefore, in order to improve TPS, Wanchain stated in its whitepaper that it will launch its own POS consensus, thus partially solving the performance issues related to TPS. Wanchain’s POS is completely different from the POS mechanism of Ethereum 2.0 Casper.
Of course, at the same time, we are also paying close attention to many good proposals from the Ethereum community, such as sharding, state channels, side chains, and the Raiden network. Since blockchain exists in the world of open source, we can of course learn from other technological breakthroughs and use our own POS to further improve TPS. If we have some time at the end, I’d love to share some points about Wanchain’s POS mechanism.
Wanchain is focused on different use cases, it is to act as a bridge between different tokens and tokens, and between assets and tokens. For various cross-chain applications it is necessary to consume WAN as a gas fee to pay out to nodes.
So it seems that the purpose Ripple and Wanchain serve are quite different. Of course, there are notary witnesses in the cross-chain mechanism, that is, everyone must trust the middleman. Ripple mainly serves financial clients, banks, so essentially everyone’s trust is already there.
Neutrino: We see that Wanchain uses a multi-party computing and threshold key sharing scheme for joint anchoring, and achieves “minimum cost” for integration through cross-chain communication protocols without changing the original chain mechanism. What are the technical characteristics of multi-party computing and threshold key sharing? How do other chains access Wanchain, what is the cross-chain communication protocol here? What is the cost of “minimum cost?
Lini: The answer to this question is more technical, involving a lot of cryptography, I will try to explain it in a simple way.
In sMPC multiple parties each holding their own piece of private data jointly perform a calculation (for example, calculating a maximum value) and obtain a calculation result. However, in the process, each party involved does not leak any of their respective data. Essentially sMPC calculation can allow for designing a protocol without relying on any trusted third parties, since no individual ever has access to the complete private information.
Secure multiparty computing can be abstractly understood as two parties who each have their own private data, and can calculate the results of a public function without leaking their private data. When the entire calculation is completed, only the calculation results are revealed to both parties, and neither of them knows the data of the other party and the intermediate data of the calculation process. The protocol used for secure multiparty computing is homomorphic encryption + secret sharing + OT (+ commitment scheme + zero knowledge proofs, etc.)
Wanchain’s 21 cross chain Storeman nodes use sMPC to participate in the verification of a transaction without obtaining of a user’s complete private key. Simply put, the user’s private key will have 21 pieces given to 21 anonymous people who each can only get 1/21 part, and can’t complete the whole key.
Wanchain uses the threshold M<=N; N=21; M=16. That is to say, at least 16 Storeman nodes must participate in multi-party calculation to confirm a transaction. Not all 21 Storeman nodes are required to participate. This is a solution to the security problem of managing private keys.
Cross-chain communication protocols refers to the different communication methods used by different chains. This is because heterogeneous cross-chain methods can’t change the mechanism of the original chains. Nakamoto and Vitalik will not modify their main chains because they need BTC and ETH interoperability. Therefore, project teams that can only do cross-chain agreements to create different protocols for each chain to “talk”, or communicate. So the essence of a cross-chain protocol is not a single standard, but a multiple sets of standards. But there is still a shared sMPC and threshold design with the Storeman nodes.
The minimum cost is quite low, as can be shown with Wanchain 3.0’s cross chain implementation. In fact it requires just two smart contracts, one each on Ethereum and Wanchain to connect the two chains. To connect with Bitcoin all that is needed is to write a Bitcoin script. Our implementation guarantees both security and decentralization, while at the same time remaining simple and consuming less computation. The specific Ethereum contract and Bitcoin scripts online can be checked out by anyone interested in learning more.
Neutrino: What kind of consensus mechanism is currently used by Wanchain? In addition, what is the consensus and incentive mechanism for cross-chain transactions, and what is the purpose of doing so? And Wanchain will support cross-chain transactions (such as BTC, ETH) on mainstream public chains, asset cross-chain transactions between the alliance chains, and cross-chain transactions between the public and alliance chains, how can you achieve asset cross-chain security and privacy?
Lini: It is now PPOW (Permissioned Proof of Work), in order to ensure the reliability of the nodes before the cross-chain protocol design is completed, and to prepare to switch to POS (as according to the Whitepaper roadmap). The cross-chain consensus has been mentioned above, with the participation of a small consensus (at least 16 nodes) in a set of 21 Storeman nodes through sMPC and threshold secret sharing.
In addition, the incentive is achieved through two aspects: 1) 100% of the cross chain transaction fee is used to reward the Storeman node; 2) Wanchain has set aside a portion of their total token reserve as an incentive mechanism for encouraging Storeman nodes in case of small cross-chain transaction volume in the beginning.
It can be revealed that Storeman participation is opening gradually and will become completely distributed and decentralized in batches. The first phase of the Storeman node participation and rewards program is to be launched at the end of 2018. It is expected that the selection of participants will be completed within one quarter. Please pay attention to our official announcements this month.
In addition, for public chains, consortium chains, and private chains, asset transfer will also follow the cross-chain mechanism mentioned above, and generally follow the sMPC and threshold integration technology to ensure cross-chain security.
When it comes to privacy, this topic will be bigger. Going back to the Wanchain Whitepaper, we have provided privacy protection on Wanchain mainnet. Simply put, the principle is using ring signatures. The basic idea is that it mixes the original address with many other addresses to ensure privacy. We also use one-time address. In this mechanism a stamp system is used that generates a one-time address from a common address. This has been implemented since our 2.0 release.
But now only the privacy protection of native WAN transactions can be provided. The protection of cross-chain privacy and user experience will also be one of the important tasks for us in 2019.
Neutrino: At present, Wanchain uses Storeman as a cross-chain trading node. Can you introduce the Storeman mechanism and how to protect these nodes?
Lini: Let me one problem from two aspects.
Neutrino: On December 12th, the mainnet of Wanchain 3.0 was launched. Wanchain 3.0 opened cross-chain transactions between Bitcoin, Ethereum and ERC20 (such as MakerDao’s stable currency DAI and MKR). What does this version mean for you and the industry? This upgrade of cross-chain with Bitcoin is the biggest bright spot. So, if now you are able to use Wanchain to make transactions between what is the difference between tokens, then what is the difference between a cross chain platform like Wanchain and cryptocurrency exchanges?
Lini: The release of 3.0 is the industry’s first major network which has crossed ETH and BTC, and it has been very stable so far. As mentioned above, many cross-chain, password-protected theoretical designs are very distinctive, but for engineering implementation, the whether or not it can can be achieved is a big question mark. Therefore, this time Wanchain is the first network launched in the world to achieve this. Users are welcome to test and attack. This also means that Wanchain has connected the two most difficult and most challenging public networks. We are confident we will soon be connecting other well-known public chains.
At the same time of the release of 3.0, we also introduced cross chain integration with other ERC20 tokens in the 2.X version, such as MakerDao’s DAI, MKR, LRC, etc., which also means that more tokens of excellent projects on Ethereum will also gradually be integrated with Wanchain.
Some people will be curious, since Wanchain has crossed so many well-known public chains/projects; how is it different with crypto exchanges? In fact, it is very simple, one centralized; one distributed. Back to the white paper of Nakamoto, is not decentralization the original intention of blockchain? So what Wanchain has to do is essentially to solve the bottom layer of the blockchain, one of the core technical difficulties.
Anyone trying to create a DEX (decentralized exchange); digital lending and other application scenarios can base their application on Wanchain. There is a Wanchain based DEX prototype made by our community members Jeremiah and Harry, which quite amazing. Take a look at this video below.
Neutrino: What are the specific application use cases after the launch of Wanchain 3.0? Most are still exploring small-scale projects. According to your experience, what are the killer blockchain applications of the future? What problems need to be solved during this period? How many years does it take?
Lini: As a cross-chain public chain, we are not biased towards professional developers or ordinary developers, and they are all the same. As mentioned above, we provide a platform as infrastructure, and everyone is free to develop applications on us.
For example, if it is a decentralized exchange, it must be for ordinary users to trade on; if it is some kind of financial derivatives product, it is more likely to be used by finance professionals. As for cross-chain wallets which automatically exchange, I’m not sure if you are talking about distributed exchanges, the wallet will not be “automatic” at first, but you can “automatically” redeem other tokens.
Finally, the remaining WAN tokens are strictly in accordance with the plan laid out in the whitepaper. For example, the POS node reward mentioned above will give 10% of the total amount for reward. At the same time, for the community, there are also rewards for the bounty program. The prototype of the DEX that I just saw is a masterpiece of the overseas community developers, and also received tokens from our incentive program.
Neutrino community member’s question: There are many projects in the market to solve cross-chain problems, such as: Cosmos, Polkadot, what are Wanchain’s advantages and innovations relative to these projects?
Lini: As I mentioned earlier, Cosmos and pPolkadot all proposed very good solutions in theory. Compared with Wanchain, I don’t think that we have created anything particularly unique in our theory. The theoretical basis for our work is cryptography, which is derived from the academic foundation of scholars such as Yao Zhizhi and Silvio Micali. Our main strong point is that we have taken theory and put it into practice..
Actually, the reason why people often question whether a blockchain project can be realized or not is because the whitepapers are often too ambitious. Then when they actually start developing there are constant delays and setbacks. So for us, we focus on completing our very solid and realizable engineering goals. As for other projects, we hope to continue to learn from each other in this space.
Neutrino community member Amos from Huobi Research Institute question: How did you come to decide on 21 storeman nodes?
Lini: As for the nodes we won’t make choices based on quantity alone. The S in the POS actually also includes the time the tokens are staked, so that even if a user is staking less tokens, the amount of time they stake them for will also be used to calculate the award, so that is more fair. We designed the ULS (Unique Leader Selection) algorithm in order to reduce the reliance on the assumption of corruption delay (Cardano’s POS theory). which is used for ensuring fairness to ensure that all participants in the system can have a share of the reward, not only few large token holders.
Wu Di, a member of the Neutrino community: Many big exchanges have already begun to deploy decentralized exchanges. For example, Binance, and it seems that the progress is very fast. Will we be working with these influential exchanges in the future? We we have the opportunity to cooperate with them and broaden our own influence?
Lini: I also have seen some other exchange’s DEX. Going back the original point, distributed cross-chain nodes and centralized ones are completely different. I’m guessing that most exchanges use a centralized cross-chain solution, so it may not be the same as the 21 member Storeman group of Wanchain, but I think that most exchanges will likely be using their own token and exchange system. This is my personal understanding. But then, if you are developing cross chain technology, you will cooperate with many exchanges that want to do a DEX. Not only Binance, but also Huobi, Bithumb, Coinbase… And if there is anyone else who would like to cooperate we welcome them!
Neutrino community member AnneJiang from Maker: Dai as the first stable chain of Wanchain will open a direct trading channel between Dai and BTC. In relation to the Dai integration, has any new progress has been made on Wanchain so far?
Lini: DAI’s stable currency has already been integrated on Wanchain. I just saw it yesterday, let me give you a picture. It’s on the current 3.0 browser, https://www.wanscan.org/, you can take a look at it yourself.
This means that users with DAI are now free to trade for BTC, or ETH or some erc20 tokens. There is also a link to the Chainlink, and LRC is Loopring, so basically there are quite a few excellent project tokens. You may use the Wanchain to trade yourself, but since the DEX is not currently open, currently you can only trade with friends you know.

When bitcoin started, the block reward was a whopping 50 bitcoin every 10 minutes. The bitcoin code includes a statement which says that after every 210,000 blocks (or about four years, given 10 minutes per block) this reward should drop by half.

The Bitcoin halving clock on Binance Academy is determined by utilizing the accompanying formula: (Halving block - Next block height) * Average time between blocks - estimated time until the next block . Based on the rate miners are finding new blocks, we'll locate the 2020 Bitcoin splitting's effect somewhat sooner recently thought. The lower the reward for the block, the longer it takes to mine the coins. After halving, the number of Bitcoins mined will decrease. Now, there are 1800 BTC mined daily, but after May 2020, this figure will go down to 900 BTC. Halving slows down the rate at which new Bitcoins are obtained, and in doing so pushes the production date of the last Bitcoin to year 2140. AntPool mined block #630000 at 19:23 GMT with an already reduced reward. The amount decreased from 12,5 BTC to 6,25, and it will remain until the next halving in 2024. All crypto community is waiting for May when the third Bitcoin halving will happen. A week before the event, the popularity of the halving search request exceeded the maximum of ... However, if the price of Bitcoin fails to compensate for the reduction in block rewards, then this would be an unprecedented event that could change the way the Bitcoin network develops in the future. With a block reward of 1 satoshi, a single Bitcoin would need to be worth almost $10 trillion to maintain the US dollar value of block rewards—this would place the total market cap of Bitcoin ... Some days prior to Binance’s launch of the TRX staking rewards system, Justin Sun, the head of Tron Foundation and a close friend to Binance CEO Changpeng Zhao (CZ), proposed changes to the TRX reward system. Essentially, he proposes a reduction of the block reward from 32 TRX to 16 TRX per block while the highest 127 delegates (by vote) will share the remaining 160 TRX produced per block.
