I've just published the draft NIP to bring highly secure DM and group messaging to Nostr via the MLS protocol.

I've been studying this space for months now and after looking at a lot of different options, MLS (messaging layer security) stood out as the right way to approach solving DMs and group messages. It's highly scalable, an internet standard, and allows for graceful upgrading over time.

Done right – this NIP allows us to build extremely secure, uncensorable messaging clients that have no centralized coordinators or servers. Which is what I plan to do next. 😉

How is updating to this spec different to any of the previous ones from nip-04?

The major difference is that this support secure groups.

The other major benefit over NIP-17 (which is still very good for DMs) is that you get forward and post compromise security with this, meaning your messages aren't all leaked if your identity key leaks at some point in the future.
