At the latest Ethereum Core Developer Consensus meeting, developers have agreed to consider testing EIP-4788 and EIP-6987 for the Deneb upgrade.
Christine Kim, vice president of research at Galaxy, summed up the meeting in a recent article.
EIP-4788 is set to enable consensus layer state proofs at the execution layer for trustless verification by smart contracts.
Previously, PR #3175 was being formatted as an EIP, but will now be changed to EIP-6987. This change is intended to improve security by preventing slashed validators from being elected as block proposers.
The developers also discussed introducing an additional variable and constant in the Deneb specification to allow the execution layer more flexibility in adjusting the maximum number of blob transactions per block independently of the consensus layer.
During the meeting, Ethereum core developer Tim Beiko reminded the consensus layer client team of the compatibility of the new SSZ type introduced by EIP-4844 with upcoming SSZ upgrades or optimizations to the current RLP standard. Developers will continue to discuss this at the upcoming ACDE conference call next week.
Additionally, a revamp of the Beacon Chain Proof-of-Stake (PoS) subnet (attnet) launched on May 4. The developers also discussed PR #317 on the Beacon Chain API Github repository.
In light of the recent MEV-Boost exploit, relayers now validate block content before broadcasting via gossip. This feature requires custom forks in Lighthouse and Prysm clients.
Lighthouse developer Michael Sproul proposed a standard query parameter to enable the same functionality on all consensus layer clients.
However, Prysm developer Terence Tsao warned that introducing this feature in some ways could increase reliance on MEV-Boost, an ad-hoc software for earning MEV on Ethereum, and suggested dropping it in favor of PBS .
