Commit-Boost is an open-source public good designed to be backwards compatible with the PBS market while returning autonomy and power back to Ethereum’s validator set. With these capabilities Ethereum’s validators can constraint builders and build blocks as they see fit (i.e., inclusion lists, preconfs, etc). Specifically, Commit-Boost is a new sidecar that acts as a lightweight validator sidecar for validators to define constraints on builders. The project focuses on standardizing the final stage of communication between validators and third-party protocols. Built from scratch in Rust, Commit-Boost emphasizes safety and modularity. It is designed not to constrain downstream innovation, accommodating diverse stakeholders, proposer flows, commitment strategies, and enforcement mechanisms. Commit-Boost has no venture backing, tokens, or monetization plans. It is supported entirely by community grants from across Ethereum. Despite being relatively new, Commit-Boost has delivered strong results. We shipped an audited sidecar with over 50% performance improvement versus benchmarks. The project has seen contributions from over 20 individuals across multiple teams, and today, roughly 10% of Ethereum mainnet validators are already using Commit-Boost. Additionally, teams working on proposer commitments are all actively building on top of it (mostly in the for of preconfs which are critical to Ethereum’s roadmap), highlighting its growing ecosystem and impact. With Commit-Boost now live in production, we will use grant funding to support a full-time developer focused on two critical areas: 1) Sustainment: As adoption grows, Commit-Boost will require continuous development, refinement, and feature enhancements based on real-world usage and validator feedback. 2) Hard Fork Support: Historically, the burden of testing critical out-of-protocol infrastructure during hard forks has fallen on core developers and researchers. Commit-Boost aims to relieve this pressure by becoming a dedicated resource for ensuring smooth transitions and comprehensive test coverage. We’re deeply grateful for the Octant and Ethereum’s support in helping us grow Commit-Boost into a resilient, community-driven public good.

Validator sidecar to restore power back to Ethereum’s validators and reduce risk for Ethereum as a whole.

Validators have lost autonomy. There are multiple forks of sidecars and no way to run one sidecar to support multiple commitments creating fragmentation.

Unified sidecar with tools and functionality to support proposers to have autonomy over their block.
