Mev-commit is designed as an out of protocol layer to systems like mev-boost, facilitating the exchange of execution bids and commitments between mev actors, solving for coordination inefficiencies. This design ensures that only necessary parts of this faciliation happen on mev-commit (bids, commitments, settlement) and not the transaction flow itself. This design achieves chain abstraction by its nature, as any transaction hash on any chain can be referred to in a mev-commit bid, and be paid in eth. Bids and commitments on mev-commit also do not rely on blockchain bottlenecks and are real-time.

Bids are received and evaluated by providers, who run decisioning logic in their own environment and may decide to issue a cryptographic commitment against whatever the bid is for. In the preconfirmation case, the minimum a commitment can be made is for inclusion of the referred transaction hash(es) in the bid on the target block number specified.

Once the commitment is recorded on the mev-commit chain, an oracle will check the target block number as it gets confirmed to see if the commitment is satisfied by the committing actor. If so, the bid amount will be rewarded to the provider. If not, the provider stake will be slashed.

Only the actors who participated in the block’s confirmation are considered for rewards or slashing. This means if Block Builder A and Block Builder B commit to a bid and the target block is built by Block Builder A, the oracle will reward or slash Block Builder A.

The architecture of the mev-commit peer-to-peer (P2P) network is designed to support instantaneous communication among network participants. The diagram below depicts how mev-commit acts as a layer on bidder and provider operations, that are external to the mev-commit network by its nature:

Network Connectivity

The network is structured to ensure robust connectivity among users and providers. Each participant node connects to a primary network node, known as a bootnode, during the initial startup phase, establishing a foundational network link.

Gateway Nodes

The subsequent diagram provides a detailed representation of the bid, commitment, and fund flows within the mev-commit framework, showcasing the efficiency and effectiveness of interactions among mev actors.
