Globally decentralized protocols like Bittorrent, Bitcoin and Tor provide users a remarkable level of censorship resistance, privacy and communication freedom. But highly centralized local communication networks can block, throttle and log users of these protocols and work with governments and private firms to surveil and harass users. Centralized communication networks historically tend toward rent-seeking behavior, do a poor job at serving last-mile communities, and are fragile during natural and manmade disasters. This talk will review decentralized alternatives for local communication and demonstrate a new open source solution called TxTenna for sending offline Bitcoin transactions over a mobile mesh network.
