1/ Curious about how XMTP's end-to-end encrypted group messaging can scale to hundreds in a single group? (Scaling to thousands is on the roadmap 👀)

Here's @nickm CTO of @ephemera, at /ethcc describing how group shared secrets work with Messaging Layer Security (MLS)

2/ By leveraging MLS, XMTP uses ratchet trees to derive the encryption keys in group chats.

Ratchet trees offer strong guarantees of who can and cannot read every message in your group chat, which most other chat protocols can't do. 💪
