The 171st Ethereum ACDE meeting: Devnet-9 needs to be launched after the launch of Devnet-10 for Dencun upgrade

Christine Kim, vice president of research at Galaxy, published a summary of the 171st Ethereum Core Developer Executive (ACDE) conference call. On September 28, developers discussed the progress of Dencun upgrade testing, early audit results of EIP-4788 and the beacon block root in EVM, the launch of the Holesky testnet, EIP-7503, preliminary feedback on zero-knowledge wormholes, and changing EIP-6780 and SELFDESTRUCT specifications only in the same transaction.
Regarding the Dencun test, the Devnet-9 release has been postponed again, and the developers plan to launch Devnet-9 at the end of September or this week. The developers also said that after the launch of Devnet-9, the 10th Devnet needs to be launched for the Dencun upgrade, and the life cycle of Devnet-10 will be relatively short. The developers will also test the workflow of the verifier to obtain MEV using the MEV-Boost software on Devnet-9 and 10.
Regarding EIP-4788, the developers said that three audits conducted by Chainsecurity, Trail of Bits and Dedaub have been completed. One of the most important findings in the audit is that users can query smart contract addresses using zero timestamps, even if no value is set for zero timestamps. Before this meeting, the Holosky testnet was launched.
Developers also discussed EIP-7503, which proposes a new privacy solution for Ethereum based on zero-knowledge cryptography that will provide stronger privacy guarantees for users' transactions than cryptocurrency mixers such as Tornado Cash. It will also provide users with a way to prove that the funds in their accounts have not been mixed by the privacy protocols supported by EIP-7503, effectively allowing users to submit "proof-of-innocence" for their accounts for regulatory and compliance purposes.
Guillaume Ballet from the Geth client team raised a small issue in the EIP-6780 specification. Ballet pointed out that the EIP specifies the behavior of SELFDESTRUCT in a post-Verkle environment.
