  Description     : MEV-Boost allows Ethereum validators to source high-MEV blocks from a competitive builder marketplace

 mev-boost is open source middleware run by validators to access a
 competitive block-building market. MEV-Boost is an initial
 implementation
 of proposer-builder separation (PBS) (https://ethresear.ch/t/proposer-
 block-builder-separation-friendly-fee-market-designs/9725) for proof-of-
 stake
 (PoS) Ethereum.
 .
 With MEV-Boost, validators can access blocks from a marketplace of
 builders. Builders produce blocks containing transaction orderflow and a
 fee for the block proposing validator. Separating the role of proposers
 from block builders promotes greater competition, decentralization, and
 censorship-resistance for Ethereum.
 .
 PoS node operators must run three pieces of software: a validator
 client, a consensus client, and an execution client. MEV-boost is a
 sidecar for the beacon node - a separate piece of open source software,
 which queries and outsources block-building to a network of builders.
 Block builders prepare full blocks, optimizing for MEV extraction and
 fair distribution of rewards. They then submit their blocks to relays.
 .
 Relays aggregate blocks from multiple builders in order to select
 the block with the highest fees. One instance of MEV-boost can be
 configured by a validator to connect to multiple relays. The
 consensus layer client of a validator proposes the most profitable block
 received from MEV-boost to the Ethereum network for attestation and
 block inclusion.
