Indeed, in the capital market, there are often stories of "you love to answer today, but tomorfa icons bitcoinrow you can't afford it", but with the current level of technology, the imagination space of the meta universe has yet to be explored, and the "bullet" must be allowed to fly for a while.
Matter Labs'ethereum hash profit zkPorter off-chain data solutionIn this regard, the Optimistic Rollup camp has not disclosed more different expansion technologies, and the advantages of removing data availability may be similar to Plasma technology. However, Arbitrum has already admitted that there will be more expansion plans, which will later coexist with Arbitrum One.
The Arbitrum team stated, “Arbitrum One is our flagship Optimistic Rollup solution, but in fact we have other solutions that will coexist with Arbitrum One. According to our earliest published academic paper, Arbitrum is the first to explore the expansion solution of the mixed data model. We will continue to explore how these ideas coexist with Arbitrum One, so stay tuned.”Can the sequencer review transactions?In the L2 network, there is a role similar to a "miner" in the first-level network, which will be responsible for processing the order of transactions and is called a sequencer. For the early L2 networks, there is currently only one Sequencer, which is the node operated by the team itself.Therefore, the Ethereum community is also very concerned about whether this single Sequencer may have centralization or transaction review issues, for example, it can selectively confirm transactions. Regarding this issue, the team stated that although there is only one Sequencer responsible for transaction sequencing in the current version of Arbitrum One mainnet, Sequencer cannot review transactions, "because users can choose to bypass Sequencer and publish them directly on the blockchain. In this way, the transaction is forced to be written into the blockchain.”In addition, in the official Arbitrum documentation (https://developer.offchainlabs.com/docs/inside_arbitrum), the team stated that it has not yet added a mechanism to punish Sequencer, because this node is officially maintained and will not perform malicious actions, but in the future Arbitrum One Will switch to a decentralized fair sorting service.
In addition to the Sequencer, the network also needs more validators (Validators) to review each transaction in real time, making the security of the network more reliable. They said, "Although there is only one Sequencer, we hope to have more verifications. To ensure the correctness of the agreement, so we will announce in the short term the well-known institutions that will participate in this verification process.”If ZK Rollup is a longer-term solution, how will Arbitrum stay competitive in the long-term?In fact, judging from the common characteristics of these platforms, they not only have elements such as "virtual identity, social networking, and diversification", but more importantly, they can provide sustainable content to enrich the entire virtual world and give users a deeper sense of immersion.
In addition to working on the content side, hardware equipment upgrades also play a role in enhancing the immersion of the meta universe. At the current stage, it is mainly reflected in the VR/AR level.Facebook CEO Zuckerberg firmly believes that VR is the next generation computing platform. With Oculus Quest2 headset shipments exceeding 5.5 million units, this prediction seems to be becoming a reality.At the same time, he emphasized that "the primary goal of all our plans is to help realize the meta-universe."In the eyes of the general public, the meta-universe can be referred to or more visualized, just like the "Oasis Oasis World" in the movie "Number One Player". Through a set of VR equipment, the male protagonist Wade Woz entered the virtual world of human salvation-Oasis, and embarked on another journey in life as Parsifal.
On August 29, the VR (virtual reality) startup Pico issued a letter to all employees, disclosing that the company was acquired by ByteDance. It is reported that the price negotiated between the two parties was around 8 billion at the beginning, and later rose to more than 9 billion. In addition, there have also been other major game companies talking to Pico.To put it simply, everyone is aiming for the next-generation gaming platform that can promote the development of Metaverse.
Of course, in addition to UGC/PGC, VR, etc., AI is considered to be the most important technical part of Metaverse. On the one hand, AI can empower the continuous and efficient production of content; second, AI can make things in the virtual world mirror the real world.For example, the sci-fi movie "Out of Control Player" released not long ago, its core fun lies in the emergent narrative brought by high-level AI NPCs. That is, NPCs in this world are no different from real people.From the perspective of the layout of major factories, the AI field is also a section that it attaches great importance to. For example, Tencent builds AI Lab artificial intelligence laboratory; ByteDance acquired AI game technology developer Shenji Intelligent; Lilith invested in AI intelligence technology developer Qiyuan World; Mihayou formed an AI "inverse business" team.Conclusion:
Looking back, it is difficult for us to figure out what components the meta universe needs.It seems that as long as the real world can be more realistically mapped into the virtual world, all products, content, and technologies are just needed. But at this stage, none of them can play a substantive role.Rather than saying that the market is concerned about Metaverse, it is better to say that there is some anxiety behind the game/Internet makers. Anxious that Roblox has a market value of more than 40 billion US dollars, they all follow UGC/PGC; Facebook launches Quest2 and immediately upgrades its own VR equipment; Zhongqingbao and Tom Cat say "good on meta universe", and the market follows crazy investment.Even anxious that cybersquatting may not be able to use the "XX Yuan universe" trademark.
The capital market wants to use the imagination of the meta-universe to tell "good stories" to be able to understand it, and to be able to understand it in the first place for major manufacturers. What is difficult to understand is that those who do not have core business and capabilities have to spend money to speculate on concepts.Tranchess is a tokenized asset management and derivatives trading protocol. It was first proposed in early 2020, and it quickly developed to its current state. Inspired by the ability of some funds to meet users' different risk preferences, Tranchess' goal is to provide different risk/return matrices from a single major fund (such as BTC) that tracks specific underlying assets. Its vision is to enhance the asset management capabilities of DeFi users, hoping to provide long-term solutions for users who hold encrypted assets for a long time.
At present, the project has been audited by Paidun and CertiK.Tranchess currently mainly includes three products: QUEEN token is a higher-yielding bitcoin tracking product; BISHOP token is a neutral coin with income delta similar to a stable currency; ROOK is a BTC tracking with 2 times leverage Token.
Queen represents a fund of funds linked to the BTCB price index. Holding Queen is equivalent to depositing BTCB in Tranchess for BTCB single currency mining. Queen's net worth is completely positively correlated with the value of BTCB. Investors can deposit their BTCB into the platform to mint into Queen, or directly use USDC to buy Queen. Holding Queen is equivalent to holding BTC, and Queen can participate in mining to obtain platform token CHESS.Bishop is one of the sub-funds of the Queen of Funds of Funds (type A sub-funds, low-risk funds), which can be regarded as a USDC income product. Bishop holders charge interest at a specific interest rate that changes weekly. Every week, the platform will read the USDC interest rate from Venus and add the premium voted by the community to the interest rate. The resulting interest rate will become Bishop's fixed interest rate next week.Bishop is essentially a capital pool. Holding Bishop is equivalent to depositing USDC in Tranchess for USDC single currency mining.Rook is the other half of the Fund of Funds Queen's sub-funds (type B sub-funds, high-risk funds). Holding Rook is equivalent to depositing BTCB on the platform, and using the deposited BTCB as a margin, borrowing from Bishop holders and continuing to purchase Enter the Queen of Funds of Funds and pay a certain amount of interest to Bishop holders.CHESS is its native token, with a total of 300 million issued. It is currently issued in BSC, but it follows the Erc-20 standard and is widely used for voting and incentives in the Tranchess ecology. CHESS holders will currently share 50% of the agreement fee income, and will vote to determine the internal interest margin imposed on ROOK holders. The team plans to put products on more blockchains in the future and add different types of underlying assets.20% of the token supply will be allocated to the core team;
5% of tokens will be provided to seed investors;15% will be reserved for future investors to use in subsequent rounds of financing;
50% of the tokens will be allocated to liquidity mining;10% of the token supply is reserved for the Tranchess ecosystem/treasury-including but not limited to partnerships, third-party services, listing fees.
The purpose of CHESS is to slowly reduce circulation within 4 years. 50% of the community rewards will be distributed on Pancake and TranchesApp.Of the 150 million tokens allocated for community incentives, 120 million are being distributed on the Tranchess app. The liquidity mining activity will continue until November 11, 2021. CHESS will be distributed to QUEEN, BISHOP and ROOK holders in a fixed ratio of 3:4:2.
In terms of products, it aims to track more underlying encrypted assets, add various fund structures through innovative synthetic derivatives, and achieve more use cases for its governance token CHESS. Tranchess is looking to expand to multiple chains and build a mature technology and marketing team to cooperate with other agreements in the ecosystem. The project plans to establish a community DAO by the end of this year to take over the governance of the agreement.In July, Tranchess Protocol completed a $1.5 million seed round of funding, led by Arrows Capital and Spartan Group, with participation from Binance Labs, Longhash Ventures, and IMO Ventures. The funds will be used to expand the product to a multi-chain system and transition to the DAO structure before the end of the year.Tranchess is a team of blockchain and financial experts who have different backgrounds and experiences around the world, covering the U.S., Europe and Asian time zones. Most of the members of the Tranchess team come from investment banks, asset management companies and hedge funds, and have extensive experience in network security for exchanges and DeFi protocols.Its co-founder is Danny Chong. Danny Chong has more than 16 years of banking experience. He was responsible for Crédit Agricole CIB's foreign exchange and fixed-rate product (FX & Rates) sales SEA department.
On September 1, the public beta version of Arbitrum, the general expansion network of Ethereum, was officially launched. At the beginning of the launch, it was sought after by many DeFi blue chip applications such as Uniswap, Sushiswap, and Curve. In less than two weeks, the amount of funds locked up reached 2.2 billion. The US dollar has surpassed the public chains of Fantom, Heco, Near, etc., and is close to the current two-tier leader polygon.The launch of Arbitrum has become a milestone in the history of Layer 2 development, and it has been praised by many as "finally there is a "true second layer"." The second layer network, or Layer 2 as we often say, generally refers to the second layer of Ethereum. Their operating logic is simply: to reduce the data processing on the main chain by performing calculations or storage outside the main chain , So as to achieve the purpose of expanding performance, but still relying on the status of the main chain security.
In fact, in the early days of Bitcoin, Layer 2 was already a topic that attracted much attention. At that time, Layer 2 was mainly used to solve the payment expansion of Bitcoin. It proposed a side chain solution including state channels and Liquid, RSK, etc. plan.After entering the era of Ethereum, in addition to the sidechain and state channel solutions that have already appeared, a new expansion plan appeared-Plasma, which was the protagonist of the early Ethereum expansion plan, but later, due to the Plasma plan Security issues, as well as the emergence of the Rollup solution and the maturity of the zero-knowledge proof technology, the Plasma solution was gradually abandoned, and the research direction turned to the current mainstream Rollup solution.
The so-called Rollup here refers to the collection of multiple transactions under the chain, compressed into a transaction, and then sent to the main network, so as to achieve the effect of saving transaction costs and reducing the amount of interaction. How to ensure the security and authenticity of the data under the Rollup chain, based on the different proof mechanisms, gave birth to two mainstream expansion solutions that we are familiar with-ZK Rollp (zero-knowledge proof) and Optimistic Rollup (fraud proof). Each has its own advantages and disadvantages in performance. As we will introduce later, the Arbitrum launched this time is the latter (subtle differences).Because the era of Ethereum sharding is in the foreseeable future, Layer 2 has always been regarded as the best solution to relay the Ethereum ecology. "The current L2 is approximately equivalent to the state of July to August last year." This is Shenyu's current Layer 2 Judgement of the track.
At present, Layer 2 is divided from the width of the application. It can be divided into two categories, general-purpose and vertical. For example, Loopring, dYdX, Synthetix are all vertical applications, and general-purpose ones include Arbitrum, zkSync, etc. It is equivalent to the "Layer 2 public chain". If there is a Layer 2 overlord in the future, then there is a high probability that it will also come out of this field.As a track that has just begun to rise, Layer 2 has high hopes from many people. Some people think that it will start a new round of "DeFi Summer", and some people think that it will give birth to a Layer 2 comparable to Ethereum. So who has it? This potential? What are the Layer 2 general-purpose projects worthy of our attention?At present, the zkSync network only supports the transfer function, and the supported currencies are relatively limited. It only supports dozens of mainstream currencies such as UNI, DAI, USDC, etc. As the ZK Rollup solution has relatively large technical difficulties in compatible EVM, it must be implemented Like Arbitrum's current features, it is not yet realistic. At the end of last month, the official also postponed the launch of the testnet zkSync2.0 (EVM version) and gradually opened the testnet in three phases, precisely for this reason.The interesting point is: in zkSync network payment gas, you can use other tokens instead, you don’t need to have ETH, for example: in Gitcoin donation, if you donate with DAI in zkSync network, you can directly use DAI as Gas fee, for those tokens that do not have a liquid market price, the fee can also be paid with other tokens.
In the zkSync network, transaction costs are mainly divided into two parts: the off-chain part and the on-chain part. The off-chain part is the calculation cost of state storage and zero-knowledge proof generation, which is fixed, and the official estimate is about 0.001 US dollars per transfer. The on-chain part is that the verifier must pay Ethereum gas to verify the zero-knowledge proof. The cost is mainly based on the gas price of the Ethereum main network, but this is several orders of magnitude cheaper than the normal ETH/ERC20 transfer cost.Proof mechanism: zero-knowledge proof
Advantages of zkSync: Every transaction data is stored on the main chain, which is more secure; it is faster to exit the second-tier network (ideally a few minutes, but the actual measurement takes about 2-3 hours).zkSync challenges: generating zero-knowledge proofs requires a lot of computing resources, and the hardware threshold for zkSync verifiers is relatively high; it is difficult to implement general smart contract functions (this is a problem that all adopters of ZK Rollup solutions currently face).
Optimism EthereumOptimism Ethereum uses the Optimistic Rollup expansion plan. On January 15 this year, the Optimism team started the trial operation of the mainnet.
