Ethereum core developers have announced the release of EIP-7732, which is the formal specification of Enshrined Proposer-Builder Separation (ePBS). EIP-7732 is an upgrade only for the consensus layer, which separates execution verification from consensus verification and embeds 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, and allows validators to play the role of builders. Builders are complex participants who build blocks to extract MEV. ePBS provides trustless exchange between proposers and builders, and enables validators to effectively utilize CPU. The implementation scheme has a Payload Timeliness Committee (PTC), which votes on the timeliness of payload releases by builders, and is a subset of the validation committee. The design of EIP-7732 is also compatible with future upgrades, such as the inclusion list.
