Dan Gould

Dan Gould leads the Payjoin Foundation, a nonprofit launched in August 2025 to advance Bitcoin privacy through practical, fee-reducing technology. Based in Taipei, he's the architect behind Payjoin Dev Kit (PDK)—open-source infrastructure that lets any wallet or exchange integrate privacy-preserving transactions. He won the Human Rights Foundation's bounty for Payjoin V2 by eliminating the server requirement that made earlier implementations vulnerable to censorship.
