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.
La mayoría de los usuarios de Bitcoin confían en los servicios de custodia Lightning para una mejor experiencia de usuario, pero sacrifican la privacidad en el proceso. Este taller interactivo explora cómo Chaumian ecash ( protocolo Cashu ) resuelve el dilema de la privacidad de la custodia. Los participantes experimentarán demostraciones prácticas que incluyen la obtención de ecash desde billetes, transferencias privadas y flujos de trabajo multiacuñación. Descubra por qué ecash podría ser la pieza clave para la adopción generalizada de Bitcoin sin vigilancia.
Quantum computers pose an existential threat to Bitcoin's cryptographic foundations, with millions of bitcoins currently vulnerable to attack. This talk examines Bitcoin's specific quantum vulnerabilities - from Satoshi's exposed P2PK coins to Taproot's quantum-vulnerable key paths - and explores BIP-360's "Pay to Quantum Resistant Hash" as an immediate defense. We'll analyze how P2QRH removes public key exposure while preserving Bitcoin's functionality, why this approach provides crucial protection before full post-quantum signatures arrive, and the implementation path forward.
