Ethereum Core Developers Launch EIP-7732
Ethereum Core developers have announced the launch of EIP-7732, which is the official specification for Enshrined Proposer-Builder Separation (ePBS). EIP-7732 is an upgrade to the consensus-only layer that will perform a verification-to-consensus verification separation, embedding the PBS directly into Ethereum's consensus layer. PBS refers to the separation of block proponents and builders. EIP-7732 includes modifications to beacon chains, fork selection rules, P2P communication, and allows validators to take on the role of builders. Builders are complex participants who build blocks to extract MEVs. The ePBS provides a trustless exchange between the proponent and builder, and enables validators to make efficient use of the CPU. This implementation has a Payload Timeliness Committee (PTC), where a subset of the validation committee votes on the timeliness of builder payload releases. EIP-7732 is also designed to be compatible with future upgrades, such as inclusion lists.
