1. New research:

    • Client Diversity Data Collection: The session discussed new research on client diversity data collection, an important aspect of the health and security of the Ethereum network.

    • Multi-client block validation: Developers also discussed research on multi-client block validation, which aims to improve the stability and security of the Ethereum network.

  2. Electra Upgrade Updates:

    • Pectra Devnet 1 is coming soon: During the meeting, developers reviewed the readiness of the Pectra (Electra) upgrade and shared that Pectra Devnet 1 is close to being ready for release. The Ethereum Foundation’s Development Operations (DevOps) team is awaiting the readiness of the Execution Layer (EL) client.

    • EIP Progress:

      • EIP-6110: Teku developer Mikhail Kalinin shared an update to the EIP-6110 specification, which adds a queue mechanism on the consensus layer (CL) for processing new validator deposit requests from the execution layer.

      • EIP-7688 and EIP-6493: Nimbus developer Etan Kissling shared the progress of the implementation of these two EIPs, which involve upgrades to Ethereum's data serialization method. Although they have not yet been officially included in the Pectra upgrade, some developers hope to include them as soon as possible.

    • PeerDAS Progress: PeerDAS Devnet 1 is live, and there are three different consensus layer client implementations. Developers are weighing multiple proposals to solve unresolved issues in the PeerDAS implementation, such as how the blob gas limit is passed between the execution layer and the consensus layer, and how the calculation of the blob base fee should be handled.

  3. Other developments:

    • Node Operator Reporting: Nethermind researcher Jorge Arce-Garro shared his team’s recent research on improving the way node operators report client diversity data, funded by the Ethereum Foundation.

    • Execution Layer Cross-Validation: Geth developer Péter Szilágyi shared an update on his team’s work on supporting execution layer (EL) cross-validation, an idea designed to increase ethereum’s resilience in the event of major bugs in major clients.

In summary, the 136th Ethereum consensus layer core developer meeting made progress in many aspects, including new research, updates on Electra upgrades, and other progress related to the stability and security of the Ethereum network. These discussions and updates are all aimed at promoting the development of the Ethereum network and improving its stability and security.
