During a recent meeting, Ethereum developers discussed progress on the Devnet-8 upgrade, with various clients actively updating it. Notably, Nethermind and Geth are making advancements with their blob transaction pools, while Besu is undergoing a significant transaction pool overhaul. Erigon is also working on its pool, targeting readiness for Devnet-9, and Prysm is investigating delays in blob sidecar reception. However, the decision was made not to support blob transactions in the mempool.
A proposal named EIP-7514, which aims to add a maximum Epoch loss limit, was discussed. This proposal aims to add a constant cap to the validator activation queue, slowing down the growth of the ETH stake percentage. Ethereum Foundation researcher Dankrad expressed support for this proposal, and it will be part of the Dencun upgrade, with the limit set to 8.
Developers also discussed the possibility of adding an opcode to the Ethereum Virtual Machine (EVM) to expose the blob’s base fee. This change would make it easier for Layer 2 solutions to determine gas prices and aligns with the BASEFEE opcode for EIP-1559 consistency.
Ethereum Devnet-8 Progress and Proposed Changes for Devnet-9 Upgrade
Additionally, updates to the EIP-4788 proposal were reviewed. These updates optimize gas usage, buffer size, and handling of invalid timestamps for beacon roots stored in EL contracts. Auditors will assess these changes, with results expected before the next ACDE meeting.
Developers also addressed a unique scenario where the system contract address is part of the state but empty at execution’s end, which was encountered during testing. This issue requires further discussion.
All these developments are planned to be part of the upcoming Devnet-9 upgrade. Ethereum core development teams aim to implement and test these changes by the next ACDC call, during which a release date for Devnet-9 will be determined.
