Matrix Conference 2024

Matrix 2.0 Is Here!
09-20, 10:15–11:00 (Europe/Berlin), LAB 3

10 years after the original launch of Matrix, and 5 years after the launch of Matrix 1.0 - we’d like to show off Matrix 2.0: the set of MSCs where Matrix finally comes of age: evolving the protocol to support communication apps which can literally outperform the mainstream alternatives.


Matrix 2.0 is a set of MSCs which, once merged, will form the biggest step change that Matrix has ever seen in terms of functionality, usability and performance. Matrix 2.0 is made up of:

  • Simplified Sliding Sync (instant login, instant sync and instant launch)
  • Native OpenID Connect for authentication
  • Native Encrypted VoIP calling over Matrix
  • Invisible encryption

We first announced the concept of Matrix 2.0 at FOSDEM 2023, and then gave a preview of progress in September, and then at FOSDEM 2024 - but by the time of this talk we believe the MSCs will be pretty much stable and ready for primetime, with native implementations in matrix-rust-sdk, Synapse, matrix-authentication-service and more.

In this talk we’ll give a tour of the MSCs, how they’ve evolved, and what they mean for developers and server admins - and celebrate that Matrix is now at the point where it can finally outperform mainstream alternatives!
