Anomos: Anomos is a pseudonymous, encrypted multi-peer-to-peer file distribution protocol. It is based on the peer/tracker concept of BitTorrent in combination with an onion routing anonymization layer, with the added benefit of end-to-end encryption. By combining these technologies, we have created a platform where by no party outside of the trusted tracker will have any information about who a peer is or what they are downloading.

Freenet: Freenet is free software which lets you anonymously share files, browse and publish “freesites” (web sites accessible only through Freenet) and chat on forums, without fear of censorship. Freenet is decentralised to make it less vulnerable to attack, and if used in “darknet” mode, where users only connect to their friends, is very difficult to detect.

OneSwarm: OneSwarm is a new peer-to-peer tool that provides users with explicit control over their privacy by letting them determine how data is shared. Instead of sharing data indiscriminately, data shared with OneSwarm can be made public, it can be shared with friends, shared with some friends but not others, and so forth. We call this friend-to-friend (F2F) data sharing.

I2P: I2P is an anonymizing network, offering a simple layer that identity-sensitive applications can use to securely communicate. All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties. Many applications are available that interface with I2P, including mail, peer-peer, IRC chat, and others.
