Layer2 has not settled yet: Arbitrum data is bright, ZK system looks to the future

Recently, Arbitrum on line one of the main network directly promote Ethernet Square to usher in a new high point, the discussion on the Ethernet Square has become very hot, in advance ETH process 1.0 ETH2.0 entered in, Layer2 are directly related to the development of large Ethernet Square The ecology is closely related, and it can be said to be the “sword of justice” to solve the current stubborn problems of Ethereum’s expansion.

The layout and exploration of Layer 2 is not a matter of the past two years, but the Rollup system that can still exist at this stage is divided into ZK Rollup and Optimistic Rollup. Due to the different degrees of difficulty in technical implementation, the first to complete and pay The practice is Optimistic, which is what we often mentioned Optimism and Arbitrum. In addition to these two major systems, Layer 2 also includes state channels and Plasma. You can refer to the following picture for the rough Layer2.

The development of Layer 2 is pioneered by Arbitrum

It can be said that Arbitrum is the best developed in the Layer 2 project based on the Optimistic Rollup principle. Since Arbitrum announced the launch of the mainnet test version Arbitrum One on August 31, the influx of resources in the circle, the enthusiasm for market hype, and the continuous increase in lock-up volume, once detonated the attention of the encryption circle, as a feasible transition solution. The distressed Ethereum has injected strong gold attracting power. On the second day of launch, Arbitrum’s mainnet lock-up volume exceeded 20 million U.S. dollars. On September 10, it broke the 100 million mark. Currently, it has 1.84 billion U.S. dollars, an increase of nearly 20 times. According to data from L2BEAT, at present, the Layer 2 network has a total lock-up volume of US$3.2 billion, and Arbitrum accounts for 57%. Arbitrum, which has experienced rapid growth, is currently growing and continues to lead the Layer 2 track project in lock-up volume.

From an ecological point of view, after the Arbitrum one testnet went online, the whitelist restriction was lifted and opened to all users, which attracted many project parties, including Uniswap , Balancer, MCDEX V3, cBridge, WePiggy, SynFutures and other projects were deployed and launched as soon as possible. Arbitrum, a more interesting phenomenon is that in addition to the big-name projects, the native “earth dog” project on Arbitrum also plays an important role in it, attracting a lot of short-term funds to come in. The statistics on the official website show that there are more than 100 projects supported by Arbitrum. A relatively rich ecological embryonic form.

In terms of technological development, Arbitrum one will still be used as a test network to verify and deploy a series of functions. In the future, it is also stepping up deployment. It was recently announced that its permission-free token bridging function will be open to all projects on October 22. According to reports, this function will be applicable to the basic functions of ERC20 tokens and the transferability on L1 and L2, and it can also allow project parties or individuals to deploy functions such as governance, snapshots, etc. to ERC20 tokens. It can be predicted that there will be new attempts in asset liquidity. In the latest news, Arbitrum announced that it will launch the next version of Arbitrum One, Arbitrum Nitro. The team expects that after Arbitrum Nitro runs, the second layer execution speed will increase by 20 to 50 times and the cost will decrease.

Optimism, the first to start the top students, has slowed growth

Optimism has launched a beta version based on the Ethereum mainnet in January this year. At that time, it received the in-depth participation of Uniswap, Compound’s planned migration, and synthetic asset Synthetix. The official announced that the mainnet will be launched at the end of March after opening a wider community public test. The plan has also been postponed later on the grounds that it only considered its own needs and did not consider the schedule and requirements of partners. Up to now, Optimism has not released more news, and the pace of development has been relatively slow, mainly for the time being Synthetix ecology. In terms of lock-up volume, Optimism temporarily ranks third with 26 million US dollars, which is a big gap with Arbitrum. This result does not rule out the influence of market sentiment and hype. On the other hand, Optimism is in transaction fees. The above is better than Arbitrum one, the two are 1.58 and 2.13 US dollars respectively. In the process of the project, Uniswap V3 was officially launched on the Optimism mainnet in July, and in August, Optimism launched a new gateway interface, allowing any ERC20 tokens to deposit and withdraw funds on Optimism. So far, everything about Optimism is still being slowly explored.

The ZKRollup department still has a long way to go

Optimistic Rollup can be compatible with EVM in the short term, and ZKRollup, which relies on zero-knowledge proof, is more interesting in terms of the consistency of the final result.

Compared with Optimisitic, ZKRollup has a larger development lineup, including Loopring, Hermez, ZkSync, Aztec, StarkEx and zkEVM. Among them, the Loopring protocol has gone through 3 versions, which support DEX transactions, transfer payments and AMM Swaps. Last month, Loopring officially released the latest version that supports Layer-2 NFT. This version supports NFT for casting on Layer-2, Transfers and transactions to reduce overall gas costs.

zkSync has gone through two versions of 1.0 and 2.0. At present, it has not completed the public testnet release in May and the main network launch in August. The progress is slightly delayed. The current situation is that zkSync 2.0 will be released in a few days. The testnet will be opened in phases after the week, and the mainnet will be launched gradually. At the end of July, StarkWare of the ZK series announced the launch of its second-tier expansion solution StarkEx 3.0 version on the mainnet, which enables L2 users to easily interact with L1, and enables new functions such as DeFi Pooling and dAMM. It plans to build a DeFi Pooling platform with the expansion team Celer .

Another new solution, zkEVM, is underway. It was initiated by the Ethereum Foundation to directly compile Solidity code into EVM bytecode without any translation, and execute bytecode directly in the virtual environment of zkEVM. Of course, this solution is not so easy to go online. The project team plans to see a prototype in about a year, but from the perspective of the implementation progress of the ZK system, this is also a relatively optimistic prediction.

In any case, the OP series and the ZK series have their own representative projects. The pace of each role in Layer 2 may be faster or slower, but their ultimate goal is to solve the expansion problem of Ethereum in the future. Therefore, this kind of follow-up is slow. The development iteration of rush will always exist. After one round of market testing, General Changsheng often changes in the ever-changing public chain structure, and actively promotes the development of the expansion field.
