MEV-Boost Protocol

MEV-Boost is an open-source middleware that allows Ethereum validators to outsource block construction to a competitive market of builders. This protocol separates the role of block production from block validation, enabling individual validators to capture more revenue without needing deep expertise in complex MEV strategies.

Builders compete to create the most profitable block, which they then offer to validators. The validator selects the most profitable block, ensuring that the network remains decentralized while maximizing rewards.

MEV-Boost has become the standard for block construction, significantly influencing how financial value flows through the Ethereum ecosystem. It demonstrates the shift toward modular blockchain design where specialized entities manage specific functions of the network.
