Nostr Web Client

Keychat is composed of several components. One-to-one chats are encrypted with the Signal protocol, small group chats are pair-wise groups aggregated from one-to-one chats, and large group chats use the MLS protocol. It also involves ecash stamps.

We haven’t written any NIPs yet; we need to write several.

I can’t decide whether to use NIP-117 or your approach for the double ratchet until you publish your own NIP.

NIP-117 reimplements the Double Ratchet algorithm using Nostr’s secp256k1 algorithm.

Keychat uses the open-source libsignal library directly; we believe this is the simplest, most reliable, and secure approach.
