bitmessage

Bitmessage is a decentralized, encrypted, peer-to-peer, trustless communications protocol that can be used by one person to send encrypted messages to another person, or to multiple subscribers. Bitmessage encrypts each users' message inbox using strong encryption and replicates it inside its P2P network mixing it with inboxes of other users in order to conceal user's identity, prevent eavesdropping and protect the network from any control. The Bitmessage communication protocol avoids sender-spoofing through strong authentication, and hides metadata from wiretapping systems. In June 2013, the software experienced a surge of new adoptions after news broke of National Security Agency email surveillance activities. Currently, the network processes several thousand private messages per day.
