Taiko airdrop storm: a project that claims to be completely decentralized and the founder who claims that the rules are opaque

The airdrop is still not over, will Taiko's word of mouth reverse? Author: flowie, ChainCatcher Editor: Marco, ChainCatcher In the early morning of May 23, Taiko announced the airdrop search page and TKO token economy model, but since the airdrop was far lower than expected and the airdrop rules were not transparent, Taiko was questioned by many community users. Being scolded for airdrop issues is nothing new, but Taiko's co-founder and CEO Daniel Wang (Daniel Wang)'s tough statement completely ignited the anger of community users and put himself on the cusp. Wang Dongxian wrote on X, “In order to avoid unnecessary controversy, we will not disclose the detailed TKO Genesis airdrop rules. Our goal is fair, but we can't satisfy everyone. Congratulations to those who received TKO and apologies to those who didn't.” Soon after, with more and more questioning and even abuse on the X platform, Wang Dong seemed to be irritated and once again stated on Discord: There is zero tolerance for any related abuse; Taiko is a partner of Galaxy, not a part-time job, is not used as a reference in Galaxy rankings, and does not account for much weight in participating in Taiko related activities on Galaxy; if they don't get an airdrop, it's because others have more points; the rules are opaque because they are transparent and unable to resolve differences, and the definition of “fair” is highly subjective. As soon as this remark came out, Taiko completely fell into a vortex of public opinion. Some users complained that “this is the worst PR response I've ever seen,” while others called on major exchanges to resolutely boycott this opaque crypto project. Taiko: Ethereum Layer2Taiko, which was born with the Golden Key, has attracted much attention since its establishment in early 2022, because its core team is almost the original team of Loopring, the well-known Ethereum Layer 2 zk-rollup protocol. Taiko's three co-creators Wang Dong, Brecht Devos, and Matthew Finestone are all from the Loopring team. Taiko co-founder and CEO Wang Dong (English name Daniel Wang), speaking to the community this time, is also the founder of Loopring. Loopring was the first zk-rollup deployed on Ethereum. Loopring was listed on Coinbase in 2020, becoming the first Chinese project to list Coinbase. Since then, it has also been launched on exchanges such as Binance and OKX, making it a splash for a while. Before joining Web3, Wang Dong was also the technical director of Zhong'an Insurance and JD, technical director and senior software engineer at Google, and participated in the establishment of Yunrang Technology, Coinport, etc. With a complex background such as a traditional Web2 giant, serial entrepreneur, Web2+Web3, etc., and has already founded a good Web3 project, Wang Dong can be said to be the most popular type of founder among investors. Soon after its establishment, Taiko attracted investment from a number of well-known investment institutions. According to RootData data, in about 2 years since its establishment, Taiko has received a total of 37 million US dollars in financing. Investors include traditional investment institutions such as Sequoia China, Yunqi Capital, BAI Capital, and GGV Capital, as well as well-known exchanges or market makers such as OKX Ventures, GSR, and Wintermute, as well as the participation of cryptographic native capital such as Hash Global, IOSG Ventures, and Generative Ventures. Taiko, on the other hand, is a Type-1 type of ZK-EVM (see article: “Vitalik: The Future of Different Types of ZK-EVM”), that is, a fully decentralized, Ethereum-equivalent zk-rollup. The zkEVM that Taiko wanted to build was originally part of Loopring's work, but during the development phase, Wang Dong and his team believed that Loopring was an application-specific extension, and Taiko wanted to build a generic extension, which would cause great confusion, so Taiko developed independently from Loopring. Why did the Taiko airdrop cause discontent? On December 27, 2022, Taiko released the first public testnet Alpha-1 testnet. Taiko announced the launch of its sixth testnet in January of this year...

Taiko: Type-1 zkEVM valued by Sequoia China

Originating from Loopring, it developed independently, and is probably one of the big winners in the next “adoption cycle.” Original article “Taiko: A New zkEVM on the Block” by umede.eth, compiled by Daily Planet JK. Editor's note: According to the Daily Planet, Taiko, a second-tier Ethereum network based on zkRollup, completed two seed rounds totaling $22 million on June 8. The first round of financing of $10 million, led by Sequoia China, ended in the third quarter of 2022. Generative Ventures led a recent second round of funding of $12 million. If you're a little concerned about zero-knowledge proof developments in the Ethereum space, you've probably heard the names Polygon, Starkware, Scroll, and zkSync. In fact, you've probably not only heard of them, but also seen them debated on Twitter about various issues: what is the real definition of zkEVM, who was/is about to deploy zkEVM for the first time on the Ethereum mainnet, who is better at marketing, and other important and less important questions. Regardless of your views on their arguments, all of these projects are trying to drive Ethereum's expansion. However, a new player is emerging, and this one is relatively low-key but as viable as the others. This new entrant is Taiko — a zkEVM that aims to be a fully decentralized, zero-knowledge extension equivalent to Ethereum. As far as I know, no other zkEVM team is currently trying to achieve this feat, so I think Taiko deserves special attention. Let's take a look at what happened to Taiko. Background Taiko (“drum” in Japanese) was founded in early 2022 by Daniel Wang, Brecht Devos, and other famous people in the field. Before starting Taiko, these two worked for Loopring, the first zero-knowledge rollup deployed on Ethereum. I think it's important to quickly understand Loopring's role in the founding and development of Taiko. Originally, the zkEVM Taiko was building must be part of Loopring's effort to bring zero-knowledge proofs-driven Ethereum to the masses. However, at some point during the development phase, Wnag and his team realized that confusing the two could be quite confusing because Loopring is an application-specific extension, while Taiko is meant to be a generic extension. As a result, Taiko separated from Loopring and developed independently. Taiko currently consists of around 20 employees from Turkey, Austria, Barbados, China, India, the United States, Canada, Ukraine, etc. Technical details The main characteristic of the Type-1 zkEVM that distinguishes Taiko from competitors (or rather, peers) is that it aims to be a Type-1 zkEVM. Type-1's zkEVM aims to be fully equivalent to Ethereum, which means it doesn't make any changes to the Ethereum system to make it easier to generate zero-knowledge proofs. Before we dive in, it's important to note that Taiko's zkEVM is an offshoot of the Privacy and Scaling Explorations (PSE) team community effort. Taiko uses this branch to test new stuff and then contribute to PSE's zkEVM so that any project developing a Type-1 zkEVM (not currently) can benefit from this research. Type-1 zkEVM wants to be fully compatible with Ethereum. In Taiko's case, it is intended to be the Ethereum equivalent at the opcode level, which means that hash functions, pre-compiled contracts, transactions and state trees, and other consistency logic will not change. However, as indicated in Taiko's white paper, the protocol does currently disable some Ethereum Improvement Proposals (eIPs), but this will change over time...

Introduction | dAMM: Addressing L2 Liquidity Fragmentation

dAMM brings L2 liquidity to L1 and aims to use L1's trustlessness to reverse the trend of liquidity fragmentation caused by the rise of L2. Not looking at AMM on L2 for too long is plagued by liquidity fragmentation issues DAMM solves the liquidity fragmentation problem by allowing different L2s to share liquidity DAMM allows ZK-based L2 (e.g., DeversiFi, Loopring, etc.) to share liquidity asynchronously — so that more transactions can be supported by liquidity providers DAMM can allow liquidity providers to participate in L2 transactions while serving L1 AMM such as Uniswap => no need for anything Scalability can be achieved through compromise DAMM uses L1's license-free nature to mitigate liquidity fragmentation issues caused by L2 being independent of each other. dAMm (formerly Caspian) In March 2021, when we first officially announced dAMm, we named it Caspian (Caspian Sea) (Chinese translation), but eventually dropped the name due to trademark issues (long live dAMm!). DAMM is an L2 AMM developed by StarkWare and Loopring in collaboration that aggregates liquidity into an L1 liquidity pool and enforces logic through L1 contracts. This greatly increases capital efficiency and development flexibility, while enjoying the security guarantees provided by L1. Expanded functionality of dAMM — Cross-L2 asynchronous DAMM's functionality has been extended to enable cross-L2 AMM, that is, have different L2s asynchronously share the same liquidity pool. This design can give AMM scalability, but it doesn't cause fragmentation of liquidity. So-called asynchronicity means that an L2 does not need to use the AMM L1 liquidity pool to communicate with other L2 when processing dAMM transactions. Asynchronicity is a core function of dAMM, making shared AMM actually usable for the first time in the real sense of the word. How did dAMm do this? Because it decouples the liquidity pool from the pricing state. Under this design, any offer provided by the agreement status of the contract, as long as it has sufficient liquidity to execute the transaction. By decoupling capital and status, we can enable each L2 to create its own DAMM state based on the same liquidity pool, enabling asynchronous cross-L2 AMM. The role of supporting multiple independent market participants still retains the previous design. The new design is unique in that it supports multiple independent markets—some on L2 and L1, but they all share AMM infrastructure and liquidity. Finally, the new design also has a minor tweak: dAMM can use L1 liquidity (for example, transactions on Uniswap/Sushiswap) to expand its liquidity pool. To this end, we support direct deposit of L1 liquidity provider tokens (for example, liquidity provider voucher tokens from the UniSwap ETH/DAI pool) into the appropriate dAMM liquidity pool (e.g., ETH/DAI liquidity pool). What are the benefits of the expanded dAMm? The expanded dAMm has obvious advantages and has created a virtuous cycle: since dAMm supports multiple markets, increased transaction volume on dAMM means increased processing fees and no change in liquidity, increased processing fees mean improved capital efficiency and increased liquidity means more favorable prices. How high is the risk of impermanent loss of dAMM? AMM's liquidity providers are subject to the risk of impermanent loss (impermanent loss). This is even more true of dAMM's liquidity providers. In fact, the more markets DAMM supports, the higher the risk of impermanent losses for its liquidity providers. In an impermanent loss neutral environment (such as Curve pools), liquidity providers don't have much risk. This is not the case with other types of liquidity pools. To mitigate this problem, dAMM smart contracts use a parameter called dAMm health factor to limit the impermanent losses experienced by liquidity providers. We'll write a separate article about this mechanism later. Conclusion We predict that dAMM will become one of the basic primitives for DeFi scaling. Furthermore, we believe this design is a strong proof of the mutually independent L2 series...

[Press Release] Luyin Monthly Report (September 2020)

September was a busy month. We completed the development of the Road Print Protocol 3.6 code and officially launched a security audit. We have also begun preparations to upgrade the relay to support 3.6. Additionally, we are continuing to polish the wallet's features and UI, and plan to invite more users for closed beta over the next two weeks. After four months of intensive development and testing, we have completed the development of the Road Print Agreement 3.6 and submitted it to the audit company for a safety audit. Compared to Protocol 3.1, version 3.6 represents a huge leap forward in the usability, flexibility, and efficiency of the Luprinting Protocol. Luyin is Ethereum's first high-performance decentralized transaction protocol based on zkRollup. We still have a lot to learn, and we believe Protocol 3.6 will be very attractive to users. You can read the article to learn more about the features of the Luyin Protocol 3.6. A few weeks ago, we announced support for AMM (automated market maker) on Layer2. We are designing an AMM contract that allows anyone to become a liquidity provider on the Luprint Exchange. Although the AMM transaction itself is built on a protocol, setting AMM parameters and adding/removing fund pool liquidity are handled by smart contracts, so different types of AMM can be created using standard smart contracts. We plan to deploy 3.6 on the Goerli testnet in November and release a beta version on the Ethereum mainnet in December. 3.6.0 is the pre-release version we submitted for audit. The auditor we chose was Least Authority because they have extensive experience and expertise in auditing zero-knowledge proof projects (such as Zcash), and have audited many blockchain projects, including Tezos, Ethereum 2.0 specification, MetaMask, and Cosmos. We have also launched an agreement 3.6.0 bug bounty program (ending November 30), and we will give LRC rewards to contributors who discover bugs. For more information on the Road Printing Agreement 3.6, you can watch the related introductory video. Luprint Exchange users: The number of registered users of the Luprint Exchange exceeded 5,900, with a maximum of 277 registrations in a single day. TVL (Total Locked Value): The value of assets on the Luyin Exchange is currently around $22.5 million, reaching a maximum of $25 million this month. Trading volume: Trading volume rebounded in September, with the highest daily transaction volume exceeding 1.61 million US dollars. Luyin Exchange launched 11 trading pairs this month: TON/ETH, BAND/USDT, WBTC/USDC, ETH/WBTC, QCAD/USDT, UNI/USDT, ADX/USDT, NIOX/ETH, KAI/USDT, PLTC/USDT. Luyin Payments added 12 tokens: UMA, STAKE, OGN, HEX, ENTRP, WNXM, NIOX, ADX, QCAD, UNI, KAI, PLTC. In addition to MetaMask, WalletConnect, and MEW wallets, the Luprint Exchange now also supports QR code login using AuEthereum wallets and Coinbase wallets. By logging in to Loopring.io, you can experience fast transactions and transfers at the second layer of Ethereum, with negligible gas fees. This month, we added support for Auther and Coinbase wallets. We are grateful to community member Federico Luzzi for creating Loopring Swap: https://swap.loopring.io/，用户可以使用简单的兑换UI界面体验路印的基于订单本的去中心化交易所. Loopring Swap open source code is: https://github.com/loopring/loopring-swap. Loopring.io continues to host liquidity mining activities. Currently, it supports 4 trading pairs: ADX/USDT, QCAD/USDT, OGN/USDT, and NIOX/ETH. Among them, qCAD is a stablecoin pegged to the Canadian dollar launched by Canada Stablecorp. Everyone is welcome to actively place orders, and the 14,000 US dollar reward is waiting for you! We will distribute liquidity mining rewards to the winners' Luyin accounts around the 1st of every month. Liquidity mining interface In addition to HummingBot and VNPY, we provide an easier to use market making tool: Autoni...

Road Print Monthly Report (May 2020)

The Luprint Exchange has matched more than 1 million transactions; we will launch a Layer-2 fast transfer feature based on the Loopring Protocol next week, which we call Loopring Pay (Loopring Pay); in addition, we will soon invite the community to test the Loopring Wallet App. Development of the Road Printing Agreement At the beginning of this month, we released the 3.5 version of the Road Printing Agreement. You can read some details about 3.5 on the related blog. At the end of the month, we also improved the agreement to allow user accounts to be distributed more evenly in the Merkel tree. This optimization will make relay fragmentation more efficient and will be of great help in further improving relay throughput. At the same time, we've also added a feature to allow a third party to help users create a trading account in 3.5, so if you transfer money to the other party through Luyin Pay, you can first help the other party create a payee account and then make a Luyin payment transfer when they don't have a Luyin account. Luyin 3.5 is the midpoint on our way to a larger goal. This larger goal is Road Print 4.0. Regarding the positioning and characteristics of 4.0, we will be disclosing them one after another in the second half of this year. The preliminary design has now been completed, and we are conducting internal discussions and feedback on the design documentation. Our engineers are also prototyping the 4.0 contract. We obtained the Solidified security audit report and made many improvements and optimizations to the Luyin Smart Wallet contract based on the feedback in the report. Based on this, we have officially released version 1.0 of the smart wallet contract code. Luprint Exchange We have improved the way Luprint Exchange manages user transaction keys. Now you use the LuPrint Exchange and don't have any passwords. Your Ethereum signature is your password. After this improvement, Luyin Exchange's trading experience is superior to many centralized exchanges. Loopring.io added 5 trading pairs this month, namely KEEP/ USDT, USDC/USDT, DXD/ETH, AUC/ETH, and RPL/ETH. We will also gradually adjust the rules and pace of coin listing in the future. https://loopring.io另外路印的交易数据也正式被全球最大数字货币数据平台CoinMarketCap收录. https://coinmarketcap.com/exchanges/loopring-exchange路印钱包安全审计后，我们最新版的钱包App已经适配了最新的智能合约代码. All features have already been tested on the Goerli network. We are currently making every effort to advance the deployment on the Ethereum mainnet, which is one step away from the main network launch. Once the main network is online, we will do our best to test the wallet's various features with real money internally, and invite community users to participate in the app testing as soon as possible. Luprint Relay LoPrint Relay has completed support for the Layer 2 fast payment (transfer) function. This feature is natively supported by the LoPrint Protocol, but we haven't prioritized it before. However, at present, the Ethereum network is getting more and more congested, and we plan to launch this feature as soon as possible to allow Luprint users to quickly transfer money between users at almost zero cost. We will first add this transfer function to the Luprint Exchange, and later we will also integrate this function into the app. As a result, starting next week, Luyin will not only be a high-performance transaction agreement, but will also become an efficient payment agreement. Currently, Ethereum is in great need of this feature, because stablecoin (especially USDT) transfers consume the most Ethereum resources and keep transfer fees high. https://twitter.com/VitalikButerin/status/1260172228282527744?s=20我们相信路印交易和路印支付将是路印钱包的杀手锏级应用. Unlike other wallets, our users aren't limited by Ethereum's congestion and high fees. The Road Print Relay is also testing the off-chain withdrawal function. Once online, users can withdraw money from the exchange without initiating an Ethereum transaction. Not only do relays not have to wait for 12 confirmations, but the processing fee for users is also much lower. There was a great improvement in both cost and time. Our engineers also optimized the server configuration, further reducing costs by approximately 30%. We are also optimizing the relay code, hoping to migrate some services to more cost-effective cloud computing platforms. Operational Statistics Since the launch of the Luyin Exchange, it has completed more than 1 million transactions. https://dune...

[Press Release] Road Printing Agreement Project Progress Report (Issue 54)

Luprinting Protocol 3.0 is getting closer to the Ethereum mainnet deployment, and we have solved most of the technical issues of the product launch. The current agreement, relay, and product development are in line with expectations. In developing the Road Printing Protocol, we have improved the way we verify transactions in the circuit. This change has increased the flexibility of the agreement, giving relays more flexibility in how and in what order to match orders. Of course, the clearing logic will still guarantee the price and transaction volume requirements of the order. We have completed the software development required for the second phase of the multi-party calculation ceremony for zero-knowledge proof of a trusted setup. The second stage is based on the first stage perpetual tau calculation. Unlike stage 1, the calculation in stage 2 relates to a specific circuit. These two stages are also critical to the safety of the circuit and protocol. Much of the code refers to Bellman's open source code, and we've also modified the libSNARK/ethSNARKs code to remain compatible with Bellman. We successfully launched the multi-party calculation ceremony for Luyin 3.0. Up to now, a total of 5 participants have completed multi-party calculations. More people will be attending our ceremony over the next week or two. Once more than 10 people have completed the calculation, we can begin the main network deployment agreement. Amby Laboratories has completed a safety audit of Road Print 3.0. We have reviewed and analyzed the contents of the audit report and made some minor improvements to the agreement. We'll post more details next week. The completion of the third party security audit also marks the successful completion of the development of the Road Print Protocol 3.0 beta4. Currently, only 5 more people are needed to complete multi-party computation, and Luyin can deploy the 3.0 protocol on the Ethereum main network. Everything is ready, but Dongfeng Light Cone Relay's third and last system-level reconstruction before it went live has basically been completed. Joint tuning and testing of various subsystems is currently being improved. Overall, this work is progressing very well. In the new structure, we plan to increase the fee system and marketing system. The fee system supports specific users to submit offline requests using different rates. It has now been developed and has entered the testing stage; the marketing module is undergoing demand analysis. We have also introduced Service Mash in microservice management to balance load among microservices, further enhancing our ability to manage clusters. After the restructuring, in addition to greatly improving performance and stability, the system also began to support account opening in seconds in terms of functionality, and the recharge time was reduced to half of the original. The cluster has also added virtual machine-level, process-level, and log-level alarm functions, and supports the push of alarm messages through DingTalk. The front-end of the front-end product supports WebSocket, which can display data changes more quickly in depth, order status, etc.; we have also optimized the TradingView chart to better display the price curve. Note: The development of the web product has now been handed over to the WeDex team. Since then, Luprint will mainly provide the development of core functions and related technical support. Operations and Markets November 4: HummingBot released version 0.18.0, which includes the Dolomite API connection module. Now people can use HummingBot to place orders directly on the Dolomite platform. November 7: We began discussions on the 2020 R&D roadmap. At present, a high degree of agreement has been reached on the overall plan, and some details have yet to be discussed and sorted out. We will release Luyin's roadmap for next year in late December. November 8: Luyin attended the World Blockchain Conference in Wuzhen and shared technology on Luyin Protocol 3.0. Nov. 8: Commercial Director Matthew FineStone attends Toronto's Ethereum DeFi Meetup. November 9: Dolomite launches limited-price margin trading. Currently, users can short or long ETH compared to DAI, and more trading pairs will be launched in the future. November 9: Commercial Director Matthew FineStone represented Luyin in Canada at the EthWaterLoo conference organized by the Ethereum core team. November 10: Wang Dong, founder of Luyin, attended the Mingde Forum hosted by the Renmin University of China North American Alumni Association and shared some of his views on blockchain, artificial intelligence, and the digital RMB DCEP. November 10: Luyin officially launched a multi-party calculation ceremony for zero-knowledge proof security settings. The ceremony was based on the calculation results of the 11th round of perpetual tau calculation. Currently, 28 blockchain teams have been invited or registered to attend the ceremony. https://loopring.org/ #...

[Press Release] Road Printing Agreement Project Progress Report (Issue 37)

In the past two weeks, we have released the design of Oedax, a road printing auction agreement; prepared and announced plans to upgrade the LRC token contract; we have also made great progress in the development of protocol 3.0. R&D Agreements We have made encouraging progress in the design and coding of the Luprint Protocol 3.0. At present, the 3.0 function has been basically developed and has officially entered the testing stage. We plan to open source all code related to the 3.0 protocol at the end of April and publish a technical white paper on Road Printing Protocol 3.0 together. We also published the design for the Luprint auction agreement Oedax. The agreement was based on a Dutch auction, but introduced a number of desirable features. Oedax complements the Luyin Agreement. The former guarantees transactions but does not guarantee prices; the former guarantees prices but does not guarantee transactions; the former is suitable for new and less liquid assets, and the latter is more suitable for markets with full circulation. At the same time, Oedax will also assist Luprint Protocol 2.0 to complete the combustion of LRC. Based on Oedax, it is also possible to design a fully decentralized IEO (Initial Exchange Offering) platform... If you are interested in launching Oedax on a public chain other than Ethereum, please contact us. We have also announced plans to upgrade the LRC token contract, and will complete the switching and distribution of LRC tokens on May 8. After the LRC is upgraded, it will change from a currency with a constant circulation to a more deflationary currency. In the near future, LOUPRIN's token burning mechanism, the LOUPRINT auction agreement Oedax, and the new version of LRC will piece together a more different LOUPRINT agreement. Meanwhile, Luprint Protocol 3.0 may open another door for the expansion of decentralized exchanges. The relay light cone relay has finished writing the code and has officially entered the integration testing phase (we will further improve the unit tests). We will work hard to launch an internal relay in a month, which means relay connections based on the Ethereum main network will also begin soon. We are also preparing API interface documentation for optical cone relays. Light Cone Relay will first be open sourced to two important partners, but will also provide cloud-based APIs for other partners, including wallets, DEXs, and market makers. If you would like to use our API, please contact us by email: service@loopring.org. Product We will start connecting UPWallet to LightCone Relay today. At the same time, we are also planning to redesign this non-custodial wallet to provide a smoother user experience and a sleeker UI interface. If you are a designer and have experience designing Canadian currency wallets, please contact us — we are looking for excellent part-time designers to work with. Market operation On March 5, 2019, Luprint Agreement Belgian engineer Brecht Devos was invited to attend the ETHCC conference held in Paris and share the design and progress of Luprint Agreement 3.0. Loopring @EthCC2019年3月6日, Luprinting Protocol issued an LRC token contract upgrade announcement. After the upgrade, LRC will change from a token with a constant circulation to a deflation token. This characteristic is due to the LRC combustion mechanism introduced in Road Printing Protocol 2.0. On March 7, 2019, Luyin COO Chen Xiaoliang was invited to participate in Bullock's 1st anniversary online interview. On March 7, 2019, the Luprint Agreement and EU compliance exchange Kriptomat held an AMA to share the Luprint ecosystem and decentralized solutions with the community. On March 8, 2019, the Luyin team held a two-day hackathon with the University of Toronto and other institutions in North America. Loopring @EthUofT2019年3月13日, Luprinting Protocol LRC officially listed on the BC Bitcoin exchange, which supports fiat and LRC transactions. On March 14, 2019, Luyin agreed to enter the Black Diamond rating. Black Diamond Ratings is a decentralized rating agency composed of 500 industry leaders with more than 2 years of experience in the coin industry. On March 15, 2019, the Luyin Agreement entered U-News. U News is a blockchain information platform owned by U Network. On March 15, 2019, the Luyin Agreement LRC officially landed on the Changelly exchange. Global users can directly use a credit card to purchase LRC in US dollars or euros on the Changelly platform.
