You guys are reinventing encrypted decentralized chat services. Ring.cx already does this, no blockchain.
lol, ring is as much decentralized as skype was in early years. you are comparing apples with oranges. Blockchain is far, far superior. It’s the innovation, DHT is not.
2/2 cause dht is only used for IP address look up, and actual conversation is p2p. That said, you can only communicate while online, which is uncompetitive.
