Somebody could build signal protocol DMs into a nostr client 🤷♂️. If these are truly just protocols, idk why an app has to or should be expected to pick just one
Discussion
In fact, if someone figured out the correct way to lean on nostr for discoverability and interoperability, but signal for DMs, there is a good chance it would outgrow signal itself. Open systems > closed systems
Yes, please, this would be great.
Signal requires a central server, though. And their current central server can only be accessed through the official apps as far as I know.
