Rockstar🎓
Top SchoolBen Edgington is a seasoned technical project consultant and product leader with nine years focused on blockchain protocol engineering and a long career spanning engineering leadership at Hitachi to leading Ethereum client development. Currently helping deliver fast finality to Ethereum Mainnet at the Ethereum Foundation, he previously founded and led Teku at ConsenSys and contributed to high-profile open-source projects like the Teku consensus client and the Solidity compiler. He combines deep mathematics training from Cambridge with hands-on protocol work—implementing consensus constants, deposit handling and LLL compiler fixes—and practical program leadership for Optimism and ConsenSys ecosystem programs. Known for bridging applied research, product ownership and developer tooling, he also authors educational material on Ethereum consensus and maintains a track record of turning complex consensus specs into production-ready software.
