"MEV-Boost is an implementation of proposer-builder separation (PBS) built by Flashbots for proof of stake Ethereum. Validators running MEV-Boost maximize their staking reward by selling their blockspace to an open market while protecting Ethereum decentralization. It is estimated that validators running MEV-Boost can increase their staking rewards by over 60%. MEV-Boost is free, open-source, neutral software built with love, for the community. For information on MEV-Boost software and roadmap, see the MEV-Boost Repository."
