Editor's note:
The Ethereum All Core Developers Execution Call (ACDE) is held every two weeks to discuss and coordinate changes to the Ethereum Execution Layer (EL). This is the 194th ACDE call. At this meeting, EIP7732, an updated analysis of the gas cost of EIP 2537 operations, and PeerDAS were discussed.
During the meeting, Geth developer Marius van der Wijden proposed a method to remove the merge-before field from the Ethereum wire protocol to reduce node bandwidth during synchronization. Christine Kim, vice president of research at Galaxy Digital, took a detailed note of the key points of the meeting, and BlockBeasts translated the original text as follows:
On August 15, 2024, the 194th call of the Ethereum Core Developers Executive (ACDE) was hosted by Alex Stokes, a researcher at the Ethereum Foundation. The meeting focused on changes and coordination issues in the execution layer (EL).
This week, developers updated on the progress of testing on the Pectra upgrade. Subsequently, the preparations for EOF code changes, which are planned to be incorporated into the Pectra development network, were discussed, and the gas cost analysis for EIP 2537 operations was updated. Prysm developer "Potuz" introduced EIP 7732, a formal proposal to establish proposer-builder separation in the Ethereum protocol. Erigon developer Giulio Rebuffo proposed removing the "totalDifficulty" field from the execution API to reduce the technical debt of Ethereum clients. Geth developer Marius van der Wijden proposed removing some pre-merge fields and messages from the Ethereum Wire protocol to reduce bandwidth consumption during node synchronization. The developers also briefly discussed rebasing the PeerDAS specification on Pectra instead of Dencun, and shared an update on their progress on the EIP 4444 implementation.
Pectra Devnets
Pectra Devnet 2 is stable. There appears to be an open issue related to merging the block builder specs and testing them on the devnet on the Devnet 2 information page. EF DevOps engineer Parithosh Jayanthi said there are also issues with Teku/Erigon nodes and Prysm clients.
The developers are aiming to launch Pectra Devnet 3 with the updated specs for EIP 7702 in two weeks. If all goes to plan, the developers plan to add EOF to the devnet, Pectra Devnet 4, thereafter.
Geth developer Marius van der Wijden shared his latest analysis of gas costs for EIP 2537. As background, the EIP creates new precompiles for BLS12-381 curve operations. It enables smart contract developers to perform operations such as signature aggregation on the BLS12-381 curve in a cost-effective manner. Van der Wijden proposed to reprice precompiles based on benchmarks he and Geth team colleague Jared Wasinger developed for BLS operations and their gas usage on various machines. Van der Wijden encouraged other developers to run their own benchmarks on EIP 2537 gas usage to verify the results.
EIP 7732
Prysm developer "Potuz" shared an update on EIP 7732, an in-protocol solution that directly connects validators with third-party block builders. Since the merger, validators have relied on intermediary participants called relays to receive blocks containing MEV rewards. EIP 7732 eliminates the need for relays, enabling validators to earn MEV in a more trustless manner. Potuz emphasized that the current design of EIP 7732 does not require changes to the execution layer (EL) or engine API. He added that EIP 7732 is also compatible with inclusion lists, a proposal that enables validators to force transactions to be included in blocks. More information on EIP 7732 can be found in this Google Slides presentation.
Reduce pre-merge technical debt
Since Ethereum’s transition to proof-of-stake, some parts of the Ethereum codebase are no longer useful or necessary. For example, the difficulty bomb, a mechanism for forcing development work to be based on proof-of-stake, makes it impossible to create blocks through proof-of-work mining after a period of time. The following two proposals aim to remove such parts of the codebase in order to improve node performance and reduce protocol complexity.
· Erigon developer Giulio Rebuffo proposes to remove the "totalDifficulty" field from the execution API.
· Geth developer Marius van der Wijden proposes to remove some pre-merge fields and messages from the Ethereum wire protocol.
Other developers gave positive feedback on both proposals during the call. Developers agreed to review both in more detail asynchronously after the call.
PeerDAS
Regarding PeerDAS, a Nimbus developer who goes by the username “Dustin” suggested speeding up the rebase of PeerDAS on top of the Pectra EIPs instead of continuing to develop PeerDAS on top of Deneb. He said there are some EIPs in Pectra that are unstable and subject to change, such as EIP 7702 and EOF. Dustin suggested rebasing PeerDAS on a stable subset of Pectra EIPs and excluding EIP 7702 and EOF transactions on the PeerDAS development network. Developers discussed other ways to start rebasing PeerDAS on Pectra. There was general support and it began moving in that direction.
Stokes reminded call participants that there will be regular Pectra testing calls starting next Monday at 2pm UTC to further coordinate devnet specs and timings.
EIP 4444
No major updates to EIP 4444. Representatives from the Nethermind and Nimbus teams said they are building a collaboration with Portal Network, an alternative network protocol for users to access expired historical data.
