According to BlockBeats, Ethereum core developers announced the launch of EIP-7732 on July 4th. This is the formal specification of Enshrined Proposer-Builder Separation (ePBS). EIP-7732 is an upgrade solely at the consensus layer, separating execution validation from consensus validation, and embedding PBS directly into Ethereum's consensus layer. PBS refers to the separation of block proposers and builders.
EIP-7732 includes modifications to the beacon chain, fork selection rules, and P2P communication. It also allows validators to play the role of builders. Builders are complex participants who build blocks to extract MEV. ePBS provides a trustless exchange between proposers and builders and enables validators to effectively utilize CPU.
The implementation plan has a Payload Timeliness Committee (PTC), which is a subset of the validation committee that votes on the timeliness of the payload published by the builder. The design of EIP-7732 is also compatible with future upgrades.
