MEV-Boost Architecture

MEV-Boost Architecture is an implementation of Proposer-Builder Separation that allows validators to outsource the construction of blocks to a network of builders. By connecting to a relay, validators can receive pre-built blocks that maximize their rewards through MEV extraction.

This system has become a standard in the Ethereum ecosystem, significantly increasing the revenue for validators. However, it also centralizes the block-building process, as only a few builders have the capability to generate highly profitable blocks.

The architecture includes various security measures to ensure that the builder cannot cheat the proposer. It is a complex system that balances the needs of validators, builders, and the overall health of the network.

The ongoing evolution of MEV-Boost is focused on improving its transparency, decentralization, and security.
