How many relays can they really be running?
Pretty sure oxen is the only group running any. Their financial model depended strictly on a token to incentivize people to run nodes and I feel like that went nowhere.
Also, while they once had Signal forward secrecy, they quit using it for some reason. Dunno why. So messages *could be decrypted if they run a mitm attack and end up getting access to the keys.
Its just kinda weird.
Probably fine for low threat models but I'd stick with OTR or OMEMO over XMPP or Simplex if you're concerned about targeted surveillance.
Well, that's good to know. Thank you.
