    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.
