Block Builder Relays

Architecture

Block Builder Relays represent a pivotal infrastructural component within Layer-2 scaling solutions for Ethereum, specifically designed to enhance transaction throughput and reduce costs. These relays operate by receiving transaction bundles from builders, validating them against current block parameters, and submitting them to the Ethereum network for inclusion. Functionally, they decouple block proposal from block propagation, fostering a more competitive and efficient market for block space. This separation allows for specialized builders to focus on optimizing transaction ordering and inclusion, while relays ensure reliable submission and adherence to network rules.
