According to Wu, in Christine Kim's summary of the 133rd Ethereum Consensus Core Developers Meeting (ACDC), the meeting mainly discussed the following important topics: block confirmation rules (this rule is used to determine whether a block will become part of the canonical chain, i.e. the longest chain, before the block is finalized. It relies on a series of assumptions about the network, such as no validator controls more than 1/3 of the staked ETH, etc.), Pectra Devnet 0 is expected to be launched within two weeks, EIP-7684 (refund deposits with different certificates. The main motivation for this code change is to prevent front-running attacks on smart contract-based staking pools), and PeerDAS (the initial alpha version of the PeerDAS specification has been created, which can greatly improve Ethereum's ability to support blob transactions).
