Cool! Now, do this for a secure communications platform that has an open-source back-end (and front-end of course), and can be federated.

Keychat is inspired by the postal system — stamps, post offices, letters.
Keychat uses Bitcoin ecash as stamps and Nostr relays as post offices.
Keychat uses Signal/MLS protocol to ensure message encryption security and meta-data privacy.
Yes, I know about Keychat. It still needs to mature some - the deb package is likely for trixie and doesn't work on my Whonix workstation, and the AppImage flickers a lot but at least seems to work. I'm also not really convinced MLS is a good idea. But Keychat is a cool nostr thingy.
Currently, Signal’s group chats primarily use the Sender Key scheme, rather than the previous pairwise-group approach.
The post compromise security of the Sender Keys group is not as strong as that of MLS groups.
