According to Wu, in Christine Kim's summary of the 132nd Ethereum Consensus Core Developers Meeting (ACDC), the meeting mainly discussed the preparation progress of Pectra Devnet 0, and the initial CL specification and test vectors have been released. The meeting also discussed some issues, including EIP-7251, whether the validator merge is defined as a CL operation or an EL operation; EIP-7549 related to the compatibility issues after removing the committee index; and recommended increasing the number of blobs. In addition, the meeting also discussed issues of research direction, including a new model for changes in Ethereum issuance policy, attestation subnets: introducing the concept of network sharding, marking the node id as a number/network shard. This network shard/number can then be used to assign topics that nodes must subscribe to for a long time, which is related to data availability sampling and the PeerDAS scheme.
