Bleep’s main advantage over some other encrypted messaging applications is the absence of central servers. This means that there are no logs stored, all metadata goes through other peers in the network.http://thehackernews.com/2014/07/bittorrent-unveiled-new-decentralized.html
“Many messaging apps are advertising privacy and security by offering end-to-end encryption for messages. But when it comes to handling metadata, they are still leaving their users exposed,” BitTorrent’s Farid Fadaie explains.
“We reimagined how modern messaging should work. Our platform enables us to offer features in Bleep that are unique and meaningfully different from what is currently available.”
OTHER ENCRYPTED CHAT PLATFORMS
Instant messaging apps that offers end-to-end encryption have surfaced fast in the wake of NSA revelations made by global surveillance whistleblower Edward Snowden.
One such promising service is Invisible.IM chat service, an anonymous Instant Messenger (IM) that leaves no trace as it is supposed to use the Tor anonymizing network to distribute chatter wrapped in OTR encryption.
Also Tor Browser Bundle is currently working on a new Privacy tool called 'Tor Instant Messaging Bundle' (TIMB), that will help you with encrypted communication to keep your online conversations private.
