## Relay Infrastructure

Relay infrastructure acts as a secure bridge between block builders and validators, ensuring that block data is communicated reliably and trustlessly. Relays perform critical checks to verify that blocks are valid according to consensus rules before passing them to the validator for signing.

This prevents malicious builders from submitting invalid blocks that could lead to slashing or chain forks. The relay also handles the auction mechanism, ensuring that the highest bidder's block is chosen.

This infrastructure is essential for the separation of duties in Ethereum's proof-of-stake model. By isolating the validator from the builder, it protects the validator's privacy and prevents potential attacks.

Reliable relays are fundamental to the stability and liveness of the network. They operate as a neutral third party, maintaining the integrity of the block production pipeline.

As the network grows, the scalability and security of relay infrastructure become increasingly important.
