以太坊开发者在 ACDC Call #141 中讨论 Pectra 升级和资源限制

以太坊开发人员召开 ACDC 第 141 号电话会议，讨论 Pectra 升级的更新以及与家庭质押者证明计算相关的问题。

Ethereum developers convened for All Core Developers Consensus (ACDC) call #141 to discuss updates to the Pectra upgrade and issues related to proof computation for home stakers.

以太坊开发者召开了全核心开发者共识 (ACDC) 第 141 号电话会议，讨论 Pectra 升级的更新以及与家庭质押者证明计算相关的问题。

On September 5, 2024, Ethereum developers gathered over Zoom for ACDC call #141, a biweekly meeting series where developers discuss and coordinate changes to the consensus layer (CL) of Ethereum, also known as the Beacon Chain. The call was chaired by Ethereum Foundation (EF) Researcher Alex Stokes.

2024 年 9 月 5 日，以太坊开发人员聚集在 Zoom 上，参加 ACDC 第 141 号电话会议，这是一个每两周一次的系列会议，开发人员在会上讨论和协调对以太坊共识层 (CL)（也称为信标链）的更改。此次电话会议由以太坊基金会（EF）研究员 Alex Stokes 主持。

Pectra Devnet 2

Debugging efforts on Pectra Devnet 2 are nearing completion. Prysm developer Terence Tsao reported that his team resolved a non-finality bug identified on the devnet and have not encountered further issues. EF Developer Operations Engineer Parithosh Jayanthi confirmed that with the Prysm bug fixed, Pectra Devnet 2 can be deprecated.

Pectra Devnet 2 的调试工作已接近完成。 Prysm 开发人员 Terence Tsao 报告称，他的团队解决了开发网络上发现的非最终性错误，并且没有遇到进一步的问题。 EF 开发人员运营工程师 Parithosh Jayanthi 确认，随着 Prysm 错误的修复，Pectra Devnet 2 可以被弃用。

Jayanthi also mentioned that not all client teams need to be ready to launch Pectra Devnet 3. The devnet can go live with a few implementations, and others can be added later. Stokes noted that issues with EIP 7702 may need to be addressed in execution layer (EL) clients before they can be added to the devnet.

Jayanthi 还提到，并非所有客户端团队都需要准备好启动 Pectra Devnet 3。devnet 可以通过一些实现上线，其他实现可以稍后添加。 Stokes 指出，EIP 7702 的问题可能需要在执行层 (EL) 客户端中解决，然后才能添加到开发网络。

Pectra Specification Updates

Pectra 规格更新

Several updates to the Pectra implementation on the CL side were discussed. The first was an update to EIP 7251, resolving an edge case where the correlation penalty applied to validators with a high amount of staked ETH was incorrectly computed. This fix is in its final review phase and will be merged into Pectra CL specifications soon.

讨论了 CL 端 Pectra 实施的多项更新。第一个是对 EIP 7251 的更新，解决了一个边缘情况，即对持有大量 ETH 的验证者应用的相关性惩罚计算不正确。此修复正处于最终审查阶段，并将很快合并到 Pectra CL 规范中。

Another update involved improving the efficiency of accessing and storing certain components of the EL payload in the Beacon block body. This change is also nearing finalization.

另一项更新涉及提高在 Beacon 块体中访问和存储 EL 有效负载的某些组件的效率。这一变化也已接近最终确定。

Geth developer Felix Lange proposed a new strategy for improving the communication of validator withdrawals and consolidation requests from the EL to the CL. This proposal aims to reduce unnecessary overhead for EL and CL clients.

Geth 开发人员 Felix Lange 提出了一种新策略，用于改善从 EL 到 CL 的验证者提款和合并请求的通信。该提案旨在减少 EL 和 CL 客户不必要的开销。

Teku developer Mikhail Kalinin discussed the creation of a deposit requests queue to avoid unnecessary load on CL clients during spikes in deposit activity. This queue is also designed to prevent frontrunning attacks on withdrawals. Nimbus developer Jacek Sieka supported this idea, noting that it would make deposit caching less error-prone.

Teku 开发人员 Mikhail Kalinin 讨论了存款请求队列的创建，以避免在存款活动高峰期间给 CL 客户端带来不必要的负载。该队列还旨在防止对提款的抢先交易攻击。 Nimbus 开发人员 Jacek Sieka 支持这个想法，并指出这将使存款缓存不易出错。

Various refinements of Ethereum’s networking layer based on EIP 7549 were also discussed. These changes aim to improve CL clients' hash computation and bandwidth.

还讨论了基于 EIP 7549 的以太坊网络层的各种改进。这些更改旨在提高 CL 客户端的哈希计算和带宽。

PeerDAS Devnet 2

The latest implementation of PeerDAS is being tested locally by clients. Both the Lodestar and Nimbus teams are running a new Kurtosis configuration that spins up a private testnet. PeerDAS Devnet 2 is expected to be based on the Pectra upgrade.

PeerDAS 的最新实施正在由客户进行本地测试。 Lodestar 和 Nimbus 团队都在运行一个新的 Kurtosis 配置，该配置可以启动一个私人测试网。 PeerDAS Devnet 2预计将基于Pectra升级。

Stokes recommended reutilizing the stress tests used for the Deneb upgrade on PeerDAS testnets and increasing the blob count based on EIP 7742.

Stokes 建议重新利用 PeerDAS 测试网上用于 Deneb 升级的压力测试，并根据 EIP 7742 增加 blob 计数。

PeerDAS Proof Computations

PeerDAS 证明计算

Developers discussed how to handle proof computation for validators running on resource-constrained devices. EF Researcher Dankrad Feist suggested expediting research into distributed block building to allow home stakers to avoid proof computation and rely on more powerful nodes.

开发人员讨论了如何处理在资源受限设备上运行的验证器的证明计算。 EF 研究员 Dankrad Feist 建议加快对分布式区块构建的研究，以使家庭权益持有者避免证明计算并依赖更强大的节点。

Stokes recommended moving ahead with a solution that prepares blobs on the CL to reduce computational load. He asked Feist to create a group or Discord channel to start work on this asynchronously from the call.

Stokes 建议继续采用一种解决方案，在 CL 上准备 blob 以减少计算负载。他要求 Feist 创建一个群组或 Discord 频道，以便从通话中异步开始处理此问题。

Research Discussion

研究讨论

Nimbus developer “Dustin” proposed removing all mentions of SSZ unions from CL specifications since they are not used in CL clients. This proposal aims to better align CL specifications with existing client implementations. The Portal team, which uses SSZ unions in some way, will be consulted before finalizing the removal.

Nimbus 开发人员“Dustin”建议从 CL 规范中删除所有提及 SSZ 联合的内容，因为它们未在 CL 客户端中使用。该提案旨在使 CL 规范与现有客户端实现更好地保持一致。以某种方式使用 SSZ 工会的 Portal 团队将在最终确定删除之前进行咨询。

Developers reaffirmed the importance of the Portal network to the Ethereum protocol, highlighting that it is heavily funded and supported by the EF.

开发人员重申了 Portal 网络对以太坊协议的重要性，并强调它得到了 EF 的大力资助和支持。
