 Signal protocol =/= Signal app. WhatsApp also use signal protocol to achieve end to end encryption. 

So keychat users can’t interact with signal app users.

 So what does the protocol do? Did you throw signal into the mix for the GUI?

 The Signal protocol is only responsible for encrypting and decrypting messages.

Yeah, Keychat uses Signal protocol to encrypt / decrypt message.

 Interesting, I just read about the double ratchet algorithm: https://signal.org/docs/specifications/doubleratchet/#double-ratchet

Does this mean that users could publish their nsec and their old DMs would not be accessible?
