James Prestwich
James Prestwich is a blockchain engineer and researcher best known as a recurring co-host of the Zero Knowledge Podcast around 2020 to 2022. He founded Summa, a firm designing cross-chain financial contracts that famously ran a trustless Dutch auction spanning the Bitcoin and Ethereum blockchains, and later worked at cLabs on the Celo platform. His writing on cross-chain systems, including a widely cited guide to transaction sequencing, helped shape early thinking on interoperability and ordering.
