As the transaction supply chain evolves beyond simple PBS block building, validators are looking to better understand the upcoming solutions in the ecosystem that may provide additional means for value capture.
Mev-commit is a peer-to-peer network for exchanging execution bids and commitments, allowing stakeholders to engage in fast games like preconfirmations through real-time commitments, settled via a high-throughput permissionless blockchain. Mev-commit leverages relays as the primary service entity for validator participation, delegating block delivery-related computational work to them rather than validators. This design ensures that validators can maintain lightweight operations - a core tenet of PBS - by using simple sidecars like mev-boost or commit-boost. Mev-commit is agnostic to which sidecar solution they choose, making integration seamless regardless of their existing infrastructure.
Commit-Boost addresses growing sidecar fragmentation for validators by offering a standardized communication layer between validators and protocols. With Commit-Boost, validators run a single sidecar, but can participate in any commitment protocol including mev-commit. This is critical for reducing risk and the switching costs for proposers who want to opt into proposer commitments.
As such, mev-commit and Commit-Boost naturally work together out of the box. Mev-commit network and Commit-Boost sidecar can be used together with no disruption to validator duties; relays supporting mev-commit can be selected in Commit-Boost, and that’s all Node Operators need to do to seamlessly opt-in to mev-commit while using the Commit-Boost sidecar.
| mev-commit | Commit-Boost | |
|---|---|---|
| What is it? | Encrypted p2p network and blockchain | Validator sidecar software |
| Who runs it? | Transaction originators (searchers, solvers etc) and block builders | Validators |
| How does it integrate with Ethereum? | Uses relays for validator participation | Uses sidecar for validator participation |
How They Work Together
Mev-commit operates at the network layer, connecting execution providers (block builders, relays, sequencers) with bidders (searchers, solvers, bundlers) through cryptographic commitments. While validator participation isn’t strictly necessary for mev-commit to deliver commitments, network actors see stronger execution assurance when they when validators opt into the mev-commit protocol, which de-risks preconfirmation delivery and surfaces the greatest economic value.
Commit-Boost operates at the validator layer, providing a standardized interface for validators to interact with different commitment protocols. By supporting mev-commit opted-in relays in its configuration, validators can use Commit-Boost and receive the benefits of reorg resistant execution preconfirmations from mev-commit without additional operational overhead.
This means validators can run a single sidecar (Commit-Boost) and access the enhanced value created by mev-commit's real-time commitment network while still potentially tapping into other commitments.
Setting up this powerful combination takes just a few straightforward steps:
