➤ London Upgrade"@trent_vanepps, the Ethereum Foundation's community ecological integration, announced the new project on Twitter on April 30th"Ecosystem Readiness

, aimed at getting Ethereum dev tools ready for the London network upgrade (7.14). This project will track the progress of the code base, developer tools, ecological infrastructure, etc. related to proposals like EIP-1559.

The first meeting on upgrading infrastructure in London was held on May 8. In addition to core developers, the participants included infrastructure providers, exchanges, wallets, code bases, etc.

The content of the meeting is roughly as follows:

1. In the EIP specification, the name of gasLimit in the block header is reserved instead of gasTarget. According to EIP-1559, the new gasLimit will become "200% full". It should be noted that this refers to the previous gas limit (12.5 m) instead of the current 15 m. This needs to be communicated with the miners.

2. The basefee of the first block after EIP-1559 is listed on the mainnet is calculated at 1,000,000,000.

3. Regarding the naming of multiple fields in JSON RPC, the meeting has not yet reached an agreement

4. Discussed the specification of London to upgrade the testnet Baikal for client integration (Aleut testnet will be closed soon)

The current progress of the Baikal test network is as follows:

Go Ethereum has released Geth v1.10.3, which is a maintenance release but has an important update on snap sync. Geth team leader Péter Szilágyi tweeted that this may be their last updated version, in which snapshot synchronization is not the default mode, and he encourages everyone to try it. He stated in the comments that this means the initial sync can be done in 4 hours (if your bandwidth and disks can handle that throughput).

On April 30, Ethereum developers released the first multi-client test network - Steklo on the Rayonism project, simulating the Ethereum blockchain running on the Ethereum 2.0 client, with a total of 7 clients participating. But after Steklo went online, some users couldn't process packed blocks, some couldn't sync with the network, and it was quickly shut down by developers. Core developer Protolambda said on discord that the next testnet will be launched after testing and improving synchronization performance.

➤ Verification and expansion solution Truebit launched on the mainnet

cr: Truebit

Blockchain verification expansion solution Truebit is an interactive verification protocol that enables smart contracts to safely perform off-chain complex calculations in standard programming languages ​​with lower gas fees. The protocol was launched on the mainnet on April 21 . According to TrueBit's white paper, in order to solve the computational scalability problem on the blockchain, the solution provided by TrueBit consists of two parts: on top of the dispute resolution layer there is an economic incentive layer in the form of a general The "verification game" mechanism.

Subsequently, Ethereum co-founder Vitalik Buterin published an article EVM optimistic rollup using Truebit on the ethresear.ch technical forum. The article assumes that Truebit is a black box that provides delayed answers to queries about "running code and returning output", and gives a solution on how to build EVM optimistic rollup based on Truebit.

The centralized exchange OKEx has announced a partnership with Arbitrum, the Ethereum L2 scaling solution. Users of OKEx will be able to deposit and withdraw funds directly in Arbitrum without interacting with the Ethereum mainnet. The Arbitrum Rollup protocol launched its candidate testnet V4 version on March 25, and when its team confirms the mainnet release date, OKEx will begin the work of integrating Arbitrum.

➤ The transaction volume of projects based on the StarkEx expansion solution exceeds 1 billion US dollars

Currently, the projects using StarkEx, the Ethereum zkRollup expansion solution, include dydx, Deversifi and Immutable. The StarkWare team tweeted on May 7 that the combined transaction volume of projects using its solution has exceeded $1 billion. Among them, about 75% came from the dydx protocol using StarkEx Rollup, and about 25% came from DeversiFi and Immutable using StarkEx Validium.

➤ StarkWare online workshop in Chinese community

ECN, together with imToken, ETHPlanet, EthFans, Shanghai Frontier Technology Seminar, HiBlock and many other outstanding Ethereum ecological partners, jointly organized a series of activities themed "Ethereum Expansion". On May 9th, the third event in the series invited the StarkWare team and the Chinese community to hold an online workshop. Below is the bilingual video of the workshop:

➤ Uniswap v3 was launched on the mainnet on May 6, and the current lock-up volume is nearly 600 million US dollars

Uniswap v3 was launched four days ago, and features such as "aggregated liquidity", "NFT positions", "fee customization", and "range orders" have been launched, and the Optimistic Rollup expansion plan has not yet been launched. As of the publication of this article, the locked-up volume of Uniswap v3 after the migration is close to 600 million US dollars, and the daily trading volume exceeds 470 million US dollars.

According to official documents, the Uniswap v3 version can theoretically "increase capital efficiency by 4000 times". On its data page, there is a set of more intuitive data reflecting the capital efficiency between different versions, that is, the ratio of transaction volume to lock-up volume (Volume/TVL ). As of the publication, the V3 version is 85.12%, while the V2 is 26.39%. It is worth noting that v2 may still provide a better price at the current stage, and Uniswap will recommend users to choose a version with a better price when trading.
