ChainCatcher news, according to The Block, Ethereum Foundation researcher Justin Drake proposed a new consensus layer upgrade called "Beam Chain" at the Devcon conference, referred to by the community as "Ethereum 3.0". This proposal aims to achieve faster block times, lower validator staking requirements, "chain snarkifaction", and quantum-safe improvements. The core of Beam Chain lies in the introduction of technologies like zkVM, significantly enhancing the scalability of the Ethereum mainnet, potentially without relying on Layer 2 solutions.Doug Colkitt, founder of Ambient Finance, stated that the localization of zkEVM could completely eliminate gas limits, allowing nodes to only verify snarks, theoretically achieving infinite scalability for L1. Nevertheless, this proposal may lead to further centralization of block building.Drake emphasized that the final implementation of Beam Chain requires community consensus and called it his "most ambitious proposal to date." He previously resigned from his advisory position due to potential conflicts of interest with EigenLayer.

ChainCatcher news, Ethereum Foundation (EF) core researcher Justin Drake posted on the X platform that he will announce a significant plan tomorrow afternoon at 5 PM on the Devcon main stage.Drake stated that he has been conceptualizing a proposal to redesign the Ethereum consensus layer from scratch over the past year, aiming to propose a reliable strategy to launch an ambitious beacon chain roadmap within a reasonable timeframe. After months of deliberation with researchers and consensus developers, Drake is ready to present the proposal publicly. He emphasized that community involvement will be crucial if this new approach can achieve preliminary consensus.Drake previously labeled his speech title as "[title redacted]" in the Devcon schedule to maintain an air of mystery.

ChainCatcher news, summarized by Galaxy's Vice President of Research Christine Kim, reports that Ethereum developers held the 140th All Core Developers Consensus Call (ACDC).The meeting was chaired by Ethereum Foundation researcher Alex Stokes, discussing topics such as the development progress of the Pectra upgrade, PeerDAS, and the naming of the next Ethereum consensus layer upgrade. The developers decided to name this upgrade "Fulu" and plan to use "Fusaka" to refer to the "Fulu-Osaka" upgrade in the future.Additionally, the meeting also addressed technical issues in the Pectra development network and the progress of proposals such as EIP 7742.

ChainCatcher message, Ethereum researchers have initiated the "RIP-7560 Native Account Abstraction" proposal, aimed at introducing changes to the consensus layer protocol rather than relying solely on higher-level infrastructure. This proposal merges EIP-2938 and ERC-4337 into a comprehensive native account abstraction proposal, suggesting that Ethereum transactions be divided into multiple steps, including validation, execution, and post-transaction logic. The validity of a transaction is determined by the outcome of the transaction's validation step.

ChainCatcher news, Galaxy's Vice President of Research Christine Kim published a summary of the 120th Ethereum Core Developers Consensus (ACDE) conference call, where developers discussed and coordinated changes to the Ethereum Consensus Layer (CL). This week, developers discussed CL specification version 1.4.0-beta.3, the launch conditions for Devnet-10, and blob delay analysis conducted by software developer Gajinder Singh, who maintains the Lodestar and EthereumJS clients.A new CL code specification for the Cancun/Deneb (Dencun) upgrade was released, referred to as "The Summoning," officially tagged as version 1.4.0-beta.3 in the CL GitHub repository, including the following two major changes: mainnet KZG configuration and new gossip rules.Regarding Devnet-10, changes in CL specification version 1.4.0-beta.3 will be tested on Devnet-10. There are some obstacles to the launch of Devnet-10, waiting for the client teams to release new software. Once ready, it is hoped that Devnet-10 will be launched at some point on October 20 (as of now, it has not been launched).Representatives from the Prysm and Lighthouse client teams indicated that they would release updated versions of their software before October 20. Regarding blob delay analysis, based on Gajinder Singh's experiments on Devnet-9, the more blobs received by validators, the significantly greater the block delay. Ryan encouraged another CL team to attempt to reproduce Singh's experiment on Devnet-9 to see if they could achieve similar values and results.

ChainCatcher message, previously the U.S. Senate Finance Committee issued a request for comments to the digital asset community and other stakeholders. Polygon Labs responded, suggesting that the IRS should only tax consensus layer staking rewards when they are sold or otherwise disposed of.Polygon Labs believes that this measure upholds the principle of not taxing its property before disposal, more clearly reflects income situations, and facilitates IRS management, while remaining consistent with the principle of technological neutrality.

ChainCatcher message, Ethereum client Erigon updates its 2023 roadmap, changing its execution layer from 2 upgrades to 1, which will be named Erigon 3 (previously Erigon 4). At the same time, the consensus layer Caplin is introduced, designed to run as a single process alongside Erigon 3 or as an independent process. (source link)

ChainCatcher message, Ethereum core developer prestonvanloon.eth tweeted that the Prysm team is developing a new version and improving the issues with Prysm. During the brief anomaly event that occurred in the Ethereum consensus layer early this morning, Prysm performed poorly, but other clients did as well, while Lighthouse performed exceptionally well during this period.prestonvanloon.eth stated that the Prysm client encountered a high rate of cache misses when replaying the recent state, with some replay differences amounting to two full blocks, at a speed of up to 65 times per minute.

链捕手消息，以太坊基金会宣布，以太坊在升级协议的同时，也面临着定位的转变，在此基础上，以太坊的一个关键是远离“Eth1”和“Eth2”术语。在2021 年底，核心开发人员已经停止使用术语，已分别使用“执行层”和“共识层”来替代Eth1.0、ETH 2.0，路线图保持不变。 执行层是所有智能合约和网络规则所在的地方，而共识层确保为网络做出贡献的所有设备都按照规则行事，并惩罚那些不遵守规则的设备。在共识层准备好替换当前的挖矿系统后，这两层将合并为以太坊。 据悉，以太坊基金会的改名原因包括心智模型（避免用户认为一旦 Eth2 存在，Eth1 就不再存在）、预防诈骗、质押清晰度、包容性等原因。（来源链接）
