SimpleX has no user identitifiers of any kind. Not just no publicly exposed identities. Given the nature of nostr, I'm not sure truly identity-free messaging is possible.
Discussion
That's easy to do on Nostr with secure messaging protocols like double ratchet and probably MLS. Just add "create anonymous chat" in the UI.
It's just that relays can probably figure out who you are if you also make other Nostr requests. Maybe need a different client and relays if you want to avoid that.
There is no need to hide your ID what you need to hide is your IP
This needs to be achieved in general, not just in DMs. Without subterfuges like Tor, which greatly worsen the user experience.
nostr:npub142gywvjkq0dv6nupggyn2euhx4nduwc7yz5f24ah9rpmunr2s39se3xrj0 already did this it's working great, internal Tor plus Nip17 for Dms and Nip29 for groups is coming.
SimpleX gets around the need for identities with the use of message queues. Are you talking about a similar system? Wouldn't a nostr-based messaging system ultimately rely on the npubs of the engaged parties?
We believe that if IDs and receiving/sending addresses are differentiated, having an ID is an advantage and it does not affect metadata privacy.
I'm not being critical of anyone's approach. Just trying to understand the different approaches being taken by the various projects.
Are there plans to add login with Amber?
We are still working on developing MLS group chat, and after completing this task, we will evaluate Amber login. Since Keychat uses the Flutter development framework, it supports both iOS and Android versions, but Amber seems to only have an Android version. In any case, we will consider it.
True, but sometimes one wants an identity when messaging, just want to keep it pseudonymous and on decentralized servers.. so probably both would be good to have
Exactly.
It's like "Hey Simplex user, you want to come and do the same thing over here, have a worse experience with unreliable relays etc... AND tie your public identity, which you use for everything else, to it?"
Nostr is great for private stuff, as in private property, not as in secrecy.
