Standards as in parts of the spec, as you said in the original reply:

the new MatrixRTC spec Which is a fork of the WebRTC protocol and another “standard” on top of the REST HTTP protocol.

I should have been more specific with my language, it is federated, but specifically messages (events) are a distributed DAG, and I find the Matrix protocol overly generic for a replacement for something specific like Discord.

The end goal of Matrix is to be a ubiquitous messaging layer for synchronising arbitrary data between sets of people, devices and services
