So, what exactly is the difference between the two, because at this point I cannot tell..?!

Fopnu is a new kind of network using some of the tricks a torrent based network uses however its not a torrent network and does not process torrent or magnet files.

The network uses DHT technology to create a decentralised network mesh with other peers and all traffic is undertaken using a proprietory UDP messaging system thats then encrypted using public key methods so nosey folks like your ISP cannot see what your doing at any time, it may not stop the NSA from spying on you however but they dont bother with p2p unless your some kind of threat to the state.
