Gregory's Server🔐 Discord introduces end-to-end encryption with Messaging Layer Security (MLS) 🔐
Im really happy to see another large scale MLS deployment. It shows the technology is fit for purpose.
Discord uses MLS for key negotiation in group calls with really fine-grained Forward Secrecy and Post-Compromise Security: A new member of the group cannot decrypt any media sent in the previous epochs, and a leaving member of the group cannot decrypt any media sent in future epochs.
