Summary of the latest meeting of Ethereum core developers: New testnet will be launched next week, Consensys completes fork selection testing

Original title: "Ethereum All Core Developers Consensus Call #137 Writeup"

Editor's Note: The Ethereum All Core Developers Consensus Call (ACDC) is held every two weeks, mainly to discuss and coordinate the consensus on Ethereum Changes to the consensus layer (CL). This is the 137th conference call of ACDC. This conference covered topics such as the progress of Pectra Devnet 1 and PeerDAS Devnet 1.

During the meeting, Barnabas Busa said that the CL client team is fixing bugs from PeerDAS Devnet 1. Christine Kim, Vice President of Research at Galaxy Digital, recorded the key points of this meeting in detail, and BlockBeasts compiled the original text as follows:

On July 11, 2024, Ethereum developers held the 137th Core Developer Consensus (ACDC) via Zoom Meeting. The ACDC conference is a biweekly series of meetings where developers discuss and coordinate changes to the Ethereum Consensus Layer (CL), also known as the Beacon Chain. This week’s session was moderated by Alex Stokes, a researcher at the Ethereum Foundation (EF). Developers discussed progress on Pectra Devnet 1 and PeerDAS Devnet 1, as well as research generated from fork-choice testing led by TxRx, a research team within blockchain software company Consensys.

Pectra Devnet 1

The consensus layer and execution layer clients are ready to launch Pectra Devnet 1. Developers expect to launch the next testnet next week. A developer named "pk910" said that his team, most likely the EF DevOps team, is testing a client combination between Nethermind, Geth, Teku, Nimbus, Lodestar, and Grandine. EthereumJS and Lodestar developer Gajinder Singh later noted that the EthereumJS client is ready for testing on Pectra Devnet 1.

PeerDAS Devnet 1

EF DevOps engineer Barnabas Busa said that the CL client team is fixing bugs from PeerDAS Devnet 1. Once all client fixes are complete, Busa said developers plan to restart PeerDAS Devnet 1 this weekend. Stokes shared an update on his pull request (PR) regarding changing the hardcoded blob gas limit on EL and CL. He said he is working to define the impact of this PR on CL and EL and formalize it into an Ethereum Improvement Proposal (EIP) for possible inclusion in the Pectra upgrade.

Fork Choice Test Update

Consensys’ TxRX research team has implemented an initial version of their fork choice test generator. This test generator is designed to identify bugs in the client software that could lead to chain splits, as well as any areas where the client software deviates from the CL specification in non-trivial ways. This research was supported by a grant from EF. The team, represented by Alexander Vlasov and Mikhail Kalinin, requested feedback on their work during the conference call as they seek to refine the test suite and enable more flexible test generation. More information about the fork-choice test generator can be found here.
