Summary
🤩
Rockstar🎓
Top SchoolMark Tyneway is a cofounder and systems engineer with a decade of experience building and scaling blockchain infrastructure, currently focused on Optimism's optimistic rollups to scale Ethereum. He combines deep back-end expertise across Bitcoin (bcoin), Handshake (hsd), and multiple Rust-based Ethereum toolchains (foundry, ethers-rs) with practical protocol work such as contract migration, RPC improvements, and deployment tooling. Comfortable across languages and stacks from Node.js and Go to Rust, he has a history of performance-minded database and wallet work, plus low-level protocol cleanups that reduce technical debt. Mark’s background in neuroscience research and self-directed learning informs a systems-oriented, experimental approach to coordination problems and “internet government” design.
