About Matrix Matrix is an open protocol for decentralised, secure communications.
Matrix Manifesto We believe:
People should have full control over their own communication. People should not be locked into centralised communication silos, but instead be free to pick who they choose to host their communication without limiting who they can reach. The ability to converse securely and privately is a basic human right. Communication should be available to everyone as a free and open, unencumbered, standard and global network.
The average person does not self-host services yet. And if that comes to be, then yes, it will be common knowledge at that point. There’s also a fairly comprehensive documentation to get anyone with basic knowledge started.
