Chad Barraford is a co-founder and the technical lead of THORChain, the cross-chain decentralized exchange that lets users swap native assets — real Bitcoin for real Ethereum — without wrapping, bridging or trusting an intermediary. He found crypto in 2017 while traveling, having sold everything he owned, and built a blockchain from scratch as an academic exercise on the theory that the best way to understand a thing is to construct it from zero. He met his co-founder at a Cosmos hackathon in Berlin in 2019; the first lines of THORChain were written there, and the token launched a week later.
