  Matrix is an open standard and decentralized protocol for real-time
  communication, providing federated messaging, voice, video, and IoT
  signalling across independently operated homeservers. The Matrix
  specification defines several REST APIs (Client-Server, Server-Server,
  Application Service, Identity Service, and Push Gateway) that interoperate
  across the federation. Authentication is typically performed via Bearer
  access tokens, with newer flows using OAuth 2.0.
