On September 5, 2024, Ethereum builders gathered over Zoom for All Core Builders Consensus (ACDC) name #141, a biweekly assembly collection the place builders talk about and coordinate modifications to the consensus layer (CL) of Ethereum, also called the Beacon Chain. The decision was chaired by Ethereum Basis (EF) Researcher Alex Stokes.
Pectra Devnet 2
Debugging efforts on Pectra Devnet 2 are nearing completion. Prysm developer Terence Tsao reported that his group resolved a non-finality bug recognized on the devnet and has not encountered additional points. EF Developer Operations Engineer Parithosh Jayanthi confirmed that with the Prysm bug fastened, Pectra Devnet 2 may be deprecated.
Jayanthi additionally talked about that not all consumer groups should be able to launch Pectra Devnet 3. The devnet can go reside with a couple of implementations, and others may be added later. Stokes famous that points with EIP 7702 might should be addressed in execution layer (EL) shoppers earlier than they are often added to the devnet.
Pectra Specification Updates
A number of updates to the Pectra implementation on the CL aspect have been mentioned. The primary was an replace to EIP 7251, resolving an edge case the place the correlation penalty utilized to validators with a excessive quantity of staked ETH was incorrectly computed. This repair is in its ultimate evaluation part and shall be merged into Pectra CL specs quickly.
One other replace concerned enhancing the effectivity of accessing and storing sure parts of the EL payload within the Beacon block physique. This alteration can be nearing finalization.
Geth developer Felix Lange proposed a brand new technique for enhancing the communication of validator withdrawals and consolidation requests from the EL to the CL. This proposal goals to cut back pointless overhead for EL and CL shoppers.
Teku developer Mikhail Kalinin mentioned the creation of a deposit requests queue to keep away from pointless load on CL shoppers throughout spikes in deposit exercise. This queue can be designed to forestall frontrunning assaults on withdrawals. Nimbus developer Jacek Sieka supported this concept, noting that it could make deposit caching much less error-prone.
Varied refinements of Ethereum’s networking layer primarily based on EIP 7549 have been additionally mentioned. These modifications purpose to enhance CL shoppers’ hash computation and bandwidth.
PeerDAS Devnet 2
The newest implementation of PeerDAS is being examined regionally by shoppers. Each the Lodestar and Nimbus groups are operating a brand new Kurtosis configuration that spins up a non-public testnet. PeerDAS Devnet 2 is predicted to be primarily based on the Pectra improve.
Stokes really helpful reutilizing the stress assessments used for the Deneb improve on PeerDAS testnets and rising the blob rely primarily based on EIP 7742.
PeerDAS Proof Computations
Builders mentioned the right way to deal with proof computation for validators operating on resource-constrained gadgets. EF Researcher Dankrad Feist steered expediting analysis into distributed block constructing to permit residence stakers to keep away from proof computation and depend on extra highly effective nodes.
Stokes really helpful transferring forward with an answer that prepares blobs on the CL to cut back computational load. He requested Feist to create a gaggle or Discord channel to start out work on this asynchronously from the decision.
Analysis Dialogue
Nimbus developer “Dustin” proposed eradicating all mentions of SSZ unions from CL specs since they don’t seem to be utilized in CL shoppers. This proposal goals to raised align CL specs with current consumer implementations. The Portal group, which makes use of SSZ unions indirectly, shall be consulted earlier than finalizing the elimination.
Builders reaffirmed the significance of the Portal community to the Ethereum protocol, emphasizing that it’s closely funded and supported by the EF.
