Ethereum core developers have released EIP-7732
ChainCatcher message, Ethereum core developers announced the launch of EIP-7732, which is the official specification for Enshrined Proposer-Builder Separation (ePBS). EIP-7732 is an upgrade that is solely at the consensus layer, separating execution validation from consensus validation and directly embedding PBS into Ethereum's consensus layer. PBS refers to the separation of block proposers and builders. EIP-7732 includes modifications to the beacon chain, fork choice rules, and P2P communication, and allows validators to act as builders. Builders are complex participants who construct blocks to extract MEV.
ePBS provides a trustless exchange between proposers and builders, enabling validators to effectively utilize CPU. The implementation features a Payload Timeliness Committee (PTC), which votes on the timeliness of payloads published by builders, consisting of a subset of the validator committee. The design of EIP-7732 is also compatible with future upgrades, such as inclusion lists.
