Summary of the 171st Ethereum Core Developers Meeting (ACDE): Devnet-9 will be launched, audit status of EIP-4788, introduction of privacy transfer proposal EIP-7503, etc

ChainCatcher message, the 171st Ethereum Execution Layer Core Developer Meeting (ACDE) was held on September 28. Ethereum supporter Tim Beiko summarized the meeting, stating that the main topics discussed were:

• Progress of the Devnet developer testnet (Devnet-9 is expected to go live tomorrow, and the next step is to launch Devnet-10, primarily for testing EIP-7514, which sets the validator activation queue limit Max Epoch Churn Limit to 8, slowing the growth of ETH staking rates to allow time for designing a better validator reward scheme; once completed, it will enter the public testnet phase);

• Review of the EIP-4788 audit (mainly identified two major issues related to zero timestamps and Ring Buffer size; EIP-4788 aims to allow contracts on the EL to access the CL, primarily related to staking & MEV);

• Review of the Holesky restart (there were some issues an hour before the launch, but the network gradually stabilized afterward and achieved finality);

• Introduction of EIP-7503 (to implement privacy transfers of ETH, where users send ETH to a provably unspendable address, and then, using a new transaction type, they can provide proof that they burned the ETH and re-minted it at another address), and the removal of a small note in EIP-6780 (this EIP mainly modifies the functionality of the SELFDESTRUCT opcode, primarily to prepare for future applications of Verkle trees), etc.
