Both can be implemented on Nostr.

If you are interested in understanding the basic principles of these protocols, I highly recommend the following two videos:

If you only have one minute to learn about Keychat, take a look at this 50-word introduction.


Keychat is a chat app, built on Bitcoin ecash, Nostr protocol and Signal protocol.

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 protocol to ensure message encryption security and meta-data privacy. note1hvq…dqy0
