argante The correct solution is for users to set up owns servers, similar to XMPP or Tor. If users don't start setting up servers themselves, SimpleX won't be decentralized.
My understanding was that many such user provided servers already exist, but that SimpleX developers have refused to add them to their app this far, and that one would have to find the lists of server oneself and add them manually. I also faintly recall there was another issue when one did add them that could be solved by the app, but that hadn't been solved. I don't remember though, and this far I have not even tried SimpleX myself, since I am waiting for it to mature a bit more first.
argante However, SimpleX itself was designed to be fully decentralized.
Yeah, the original design was at least. That was the original promise. They haven't delivered on that yet.
