open network for secure, decentralized communication
Matrix specifies a set of RESTful HTTP JSON APIs as an open standard for federated Instant Messaging and VoIP (creating and managing distributed chat rooms without points of control or failure, cryptographically secure state synchronisation across an open network, etc). In Matrix, every user runs one or more Matrix clients, which connect through to a Matrix homeserver. The homeserver stores all their personal chat history and user account information. Synapse is a reference "homeserver" implementation of Matrix.
