The Payjoin Team won the 2025 MIT Bitcoin Hackathon by building proof of concept integrations for boltz.exchange, Liana, and the first known implementation of Payjoin in the browser using WASM bindings from Payjoin Dev Kit PDK to Javascript, which doubled as an interactive tutorial for how Payjoin works.
I gave a talk on the origins, history, and implications of the newly developed BIP 77 a.k.a Async Payjoin, and how this dramatic improvement in Payjoin UX opens the door to mass wallet adoption and thus huge financial and privacy savings for all of Bitcoin at large.
I did a workshop on the history of micropayments on the web, why they failed, and how the invention of the Lightning Network on Bitcoin is making that original dream for the web a reality.
