TABConf 7 2025: Bitcoin Clients and Mobile, Challenges and Possibilities with Davidson Souza and João Victor

Bitcoin is a peer to peer network, and real sovereignty means running your own client instead of trusting a third party. With most of the world on smartphones, bringing Bitcoin clients to mobile is a big unlock for decentralization, privacy, and user empowerment. In this talk, Davidson Souza and João Victor share what they built at SatsHack 2024: a BDK based wallet using Floresta, a Utreexo powered Bitcoin light client for Android. They cover verification, local transaction discovery, running continuously like a node, broadcasting directly to the P2P network, plus what worked, what hurt, and the technical challenges that make mobile clients hard and worth it.Featuring Davidson Souza and João Victor.Recorded live at TABConf 7 in 2025.
