Terence Tsao is an experienced backend engineer in the San Francisco crypto scene with eight years focused on Ethereum, cryptoeconomics, and blockchain scalability. He contributes to high-impact open-source projects—most notably Flashbots’ mev-boost, improving validator tooling for competitive block building, and the Ethereum consensus-specs where he strengthened tests and protocol correctness. At Offchain Labs and as an early Prysmatic Labs team member he blends production engineering with research-driven development to advance sharding, MEV mitigation, and Layer 2 tooling. His background in large-scale systems and test automation from Riverbed and Cisco informs a disciplined approach to reliability, observability, and maintainability. Terence pairs deep protocol knowledge with pragmatic backend skills in Go, and often surfaces value through documentation, test improvements, and hardening rather than headline features.
