In Ethereum's evolution towards scalability via rollups and layer 2 solutions, block creation duties are increasingly outsourced from proposers (validators) to external block "builders." Most designs for formalizing this proposer-builder separation (PBS) focus on enshrining a specific mechanism, such as a full block auction, to facilitate proposer-builder exchanges. However, restricting the protocol to enabling only one type of exchange may not serve proposers optimally across the diverse spectrum of potential duties they could offload.
