Proposer-Builder Separation (PBS)

An Ethereum design change that separates the roles of building blocks (choosing which transactions to include) and proposing them to the network.

Definition

An Ethereum design change that separates the roles of building blocks (choosing which transactions to include) and proposing them to the network. This prevents validators from having to become MEV extraction experts. Currently implemented through MEV-Boost, with plans to enshrine it directly into the Ethereum protocol.
