What is Matrix?

Matrix is an open-source internet protocol for secure, decentralised, real-time communication. Unlike other popular platforms like Discord, Matrix is federated. It consists of many servers, each server hosts Matrix accounts and chats. You can create an account on any Matrix server and the join other servers without having to re-create your account. One common example of federated protocol everyone uses today is email.

On Matrix, usernames are referred to as MXIDs (Matrix IDs), chats as rooms, servers as homeservers. Think of homeserver as the domain that hosts the instance. You can also group rooms together to form spaces (similar to Discord server).

In comparison to Discord:
Username = Matrix ID
Channel = Room
Server = Space1

1 Spaces are a collection of individual rooms.
