以太坊開發者在 ACDC Call #141 中討論 Pectra 升級和資源限制

以太坊開發人員召開 ACDC 第 141 號電話會議，討論 Pectra 升級的更新以及與家庭質押者證明計算相關的問題。

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.

以太坊開發者召開了全核心開發者共識 (ACDC) 第 141 號電話會議，討論 Pectra 升級的更新以及與家庭質押者證明計算相關的問題。

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，以太坊開發人員聚集在Zoom 上，參加ACDC 第141 號電話會議，這是一個每兩週一次的系列會議，開發人員在會上討論和協調對以太坊共識層(CL )（也稱為信標鏈）的更改。此次電話會議由以太坊基金會（EF）研究員 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 的調試工作已接近完成。 Prysm 開發人員 Terence Tsao 報告稱，他的團隊解決了開發網路上發現的非最終性錯誤，並且沒有遇到進一步的問題。 EF 開發人員營運工程師 Parithosh Jayanthi 確認，隨著 Prysm 錯誤的修復，Pectra Devnet 2 可以被棄用。

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 也提到，並非所有客戶端團隊都需要準備好啟動 Pectra Devnet 3。 Stokes 指出，EIP 7702 的問題可能需要在執行層 (EL) 用戶端中解決，然後才能新增至開發網路。

Pectra Specification Updates

Pectra 規格更新

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.

討論了 CL 端 Pectra 實施的多項更新。第一個是對 EIP 7251 的更新，解決了一個邊緣情況，即對持有大量 ETH 的驗證者應用的相關性懲罰計算不正確。此修復正處於最終審查階段，並將很快合併到 Pectra CL 規範中。

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.

另一項更新涉及提高在 Beacon 區塊體中存取和儲存 EL 有效負載的某些組件的效率。這項變更也已接近最終確定。

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 開發人員 Felix Lange 提出了一種新策略，用於改善從 EL 到 CL 的驗證者提款和合併請求的通訊。該提案旨在減少 EL 和 CL 客戶不必要的開銷。

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 開發人員 Mikhail Kalinin 討論了存款請求隊列的創建，以避免在存款活動高峰期間為 CL 用戶端帶來不必要的負載。該隊列還旨在防止對提款的搶先交易攻擊。 Nimbus 開發人員 Jacek Sieka 支持這個想法，並指出這將使存款快取不易出錯。

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.

也討論了基於 EIP 7549 的以太坊網路層的各種改進。這些變更旨在提高 CL 客戶端的哈希計算和頻寬。

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 的最新實作正在由客戶進行本地測試。 Lodestar 和 Nimbus 團隊都在運行一個新的 Kurtosis 配置，可以啟動一個私人測試網。 PeerDAS Devnet 2預計將基於Pectra升級。

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

Stokes 建議重新利用 PeerDAS 測試網路上用於 Deneb 升級的壓力測試，並根據 EIP 7742 增加 blob 數。

PeerDAS Proof Computations

PeerDAS 證明計算

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.

開發人員討論如何處理在資源受限裝置上執行的驗證器的證明計算。 EF 研究員 Dankrad Feist 建議加快分散式區塊建置的研究，以使家庭權益持有者避免證明計算並依賴更強大的節點。

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 建議繼續採用解決方案，在 CL 上準備 blob 以減少計算負載。他要求 Feist 創建一個群組或 Discord 頻道，以便從通話中非同步開始處理此問題。

Research Discussion

研究討論

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 開發人員「Dustin」建議從 CL 規格中刪除所有提及 SSZ 聯合的內容，因為它們未在 CL 客戶端中使用。該提案旨在使 CL 規範與現有客戶實現更好地保持一致。以某種方式使用 SSZ 工會的 Portal 團隊將在最終確定刪除之前進行諮詢。

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

開發人員重申了 Portal 網路對以太坊協議的重要性，並強調它得到了 EF 的大力資助和支持。
