I came across this the other day:
"This paper presents a proposal of a new P2P microblogging platform that is scalable, resilient to failures and attacks, does not depend on any central authority for user registration, provides easy-to-use encrypted private communication and authenticated public posts. The architecture tries to leverage from existing and proven P2P technologies such as Bittorrent and Bitcoin as much possible. Privacy is also one of the primary design concerns, no one should be able to see the user’s IP or their followers unless he explicitly shares such information. The proposed platform is comprised of three mostly independent overlay networks. The first provides distributed user registration and authentication and is based on the Bitcoin protocol. The second one is a Distributed Hash Table (DHT) overlay network providing key/value storage for user resources and tracker location for the third network. The last network is a collection of possibly disjoint “swarms” of followers, based on the Bittorrent protocol, which can be used for efficient near-instant notification delivery to many users.

Personally, I'm impressed by the creative application of Bitcoin/Bitorrent/DHT protocols to the problem of private/anonymous communication ... and the software looks very clean and usable as well. I also like that it's based on P2P technology unlike solutions such as Diaspora, which still require trusting third parties with personal data ...

Thoughts?
