The 165th Executive Meeting of Ethereum Core Developers: EIP-6466 and 6406 code changes will affect three projects including LayerZero, but they can still be upgraded

Christine Kim, vice president of research at Galaxy, posted a summary of the 165th executive meeting of Ethereum core developers. First, EIP-6466 and 6406 are code changes that update the data encoding in the two block header fields "transactions_root" and "receipts_root" from RLP to SSZ. The impact analysis of EIP-6466 and 6406 by blockchain security and audit firm Dedaub was to determine the impact of these code changes on deployed and actively used smart contracts on Ethereum. The analysis found that the SSZ update will affect three major projects: LayerZero, zkBridge (cross-chain bridge), and Telepathy (oracle machine). While those apps are affected, Dedaub director Neville Grech said all three can be upgraded to accommodate the code changes implemented through EIP 6466 and 6406. Danny Ryan said that no decision needed to be made on the implementation or timing of the transition from RLP to SSZ on this call and that the information shared by Dedaub's team should be considered in future discussions. Regarding the Cancun/Deneb test, Parithosh Jayanthi, a DevOps engineer at the Ethereum Foundation, said that the upgrade was launched on June 30, and the test network is being successfully completed to find some problems in the client implementation. Once the client issue is resolved, will attempt to send blob transactions to the network over a longer period of time to see how the network handles the load of 3 target blobs/blocks. Jayanthi emphasized that one of these issues affected staked ETH deposits and that Teku and the Prysm consensus layer client team should investigate further. Representatives from the Geth and Nethermind executive layer teams also shared issues they are actively patching in preparation for the next phase of testing in Devnet #7. Regarding the Builder Override Flag, Teku (CL) developer Mikhail Kalinin asked if the EL account team would be willing to accept the engine API changes in the Cancun upgrade. The change aims to create a boolean flag in the "get_payload" API command that will return true if the EL client of an Ethereum validator node detects censorship. Additionally, EIP-4788 introduces a new precompilation, a cost-effective smart contract operation that will expose information about the CL on the EL to prevent excessive use of storage space through code changes. This feature will unlock many use cases for decentralized applications, such as staking pools and re-staking protocols, that would benefit from trust-minimized access to CL state. Ethereum Foundation researcher Alex Stokes said the change will be incorporated into the final EIP-4788 specification for implementation in Cancún as soon as possible.
