A lifelong technologist who has been hacking since age eleven, Griffin has built software platforms for fast-growing startups and has been active in crypto since 2017. He paused his studies to co-found Halliday, which he envisions as the “Intel of blockchain,” elevating smart contracts from hardware-like primitives to a true software layer, enabling breakthrough applications to be built in hours, not years. Halliday's flagship product, Halliday Payments, creates a unified, global, crypto payments network.
