I realize now that I did not answer your question very intelligently. You did not only ask about encryption, you asked where to find info about the project.

I don't have a good answer for that question. There is a nostr telegram group at t.me/nostr_protocol where we have ongoing discussions about nostr stuff, and when I began work on this a few days ago, I posted frequently there with questions and status updates.

My hope is that we'll move discussions like that away from telegram and into nostr itself now that there is a decent nostr-based client with a telegramish interface. But I shouldn't judge the decency of my own project, time will tell whether we move to nostrgram or keep using telegram.
