Relays

Relays serves as a trusted intermediary between validators and builders. In the standard PBS flow, builders constantly submit blocks to the Relay. Validators then retrieve the most profitable block header without the body from the Relay and then submit the signed header back to Relay in return for the release of the block body containing the transactions.

ETHGas' preconf flow is quite similar to the PBS flow, with the addition that the Relay will perform an extra set of checks on blocks submitted by the builders to ensure all preconf transactions of the specific slot are included. Validators have to connect to our relay or other authorized Relays to receive the block headers, otherwise Validators may end up signing a header without honoring all preconf commitments thus resulting in slashing.

Our relay will be based on the mev-boost-relay developed by Flashbots. More details coming soon...
