Most Bitcoin users rely on custodial Lightning services for better UX, but sacrifice privacy in the process. This interactive workshop explores how Chaumian ecash (Cashu protocol) solves the custodial privacy dilemma. Participants will experience hands-on demos including claiming ecash from paper notes, private transfers, and multi-mint workflows. Learn why ecash might be the missing piece for mainstream Bitcoin adoption without surveillance.
Bitcoin's path to mass adoption faces a fundamental tension: self-custody is complex, but custodial solutions destroy privacy. This workshop tackles this problem head-on through the lens of Chaumian ecash and the Cashu protocol.
We'll start by examining why most users choose custodial Lightning despite privacy trade-offs, then demonstrate how ecash transforms custodial services into privacy-preserving tools. Through interactive activities, participants will claim ecash from physical paper notes, perform private transfers, and explore multi-mint strategies.
Key takeaways: Understanding the privacy advantages of bearer tokens, experiencing the seamless UX of ecash payments, and learning how Cashu enables private custodial Bitcoin usage. Perfect for developers, privacy advocates, and anyone interested in Bitcoin's user experience evolution.
