Bitmessage
-
I recently stumbled upon a P2P messaging program, and wonder if anyone else had heard of it or is using it.
Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.

It seems secure, but heavy on the traffic side of things, as it downloads and attempts to decode every message 'on the line'.

I've heard of it, but never looked into it. If it's looking at every message on the line, it sounds like it could be block chain based.
