matrixRTC is the world's first decentralised low-delay platform to exchange real-time data between groups of people over Matrix. The Matrix ecosystem is well known for applications such as Instant Messaging, but what if you want to transmit real-time data such as video conferences or sensor data? matrixRTC enables this new set of applications which benefit from low delay and real-time properties.

In this talk we walk through the journey from 1:1 calling towards the powerful matrixRTC framework which powers Element Call, our video conferencing solution. We also took into account scaling and resilience in a decentralised manner. Using those base building blocks, applications such as video/audio rooms, 1:1 calls or Third Room (Matrix’ interpretation of the metaverse) are just a matter of business logic.
