Matrix is an open standard for communication over the Internet. I will talk about the matrix standard, both the technical implementation and the reasons for its creation. We will focus on the changes and progress that has been made in the previous year, particularly getting the specification out of beta, and the growth of the ecosystem. Finally, the Matrix environment continues to develop, and we’ll look at the roadmap for the future.
