EIP-7732: Enshrined Proposer-Builder Separation proposal was officially created. This EIP fundamentally changes the way an Ethereum block is validated by decoupling the execution validation from the consensus validation both logically as well as temporally. It does so by introducing a new optional attribution (being a builder) and a new duty (submitting payload timeliness attestations ) to Ethereum validators.
