bitcoin++ Berlin, payments edition

bitcoin++ Berlin, payments edition, is a three-day gathering of builders, researchers, and protocol contributors focused on the practical side of payments on bitcoin. Across two stages, attendees can expect talks, workshops, and hackathon sessions covering topics like Lightning wallets, Cashu ecash, Fedimint, privacy-preserving payment protocols, and open-source infrastructure. The event emphasizes code, field notes, and collaborative building rather than passive spectating, making it a hands-on technical conference rather than a general industry showcase.

The event is best suited for developers, protocol engineers, and technical contributors already working on or curious about bitcoin payment rails, along with founders and researchers exploring open-source bitcoin tooling. With 15 accepted speakers drawn from projects like Cashu, Fedimint, ZEUS, and BlindBit, attendees get direct access to the people building core payment infrastructure. Anyone looking to deepen their technical understanding of bitcoin payments, network with active open-source contributors, or contribute to ongoing projects during the hackathon track should consider attending.
