I2P Network
The Invisible Internet Project (I2P) is an anonymous network layer that allows for censorship-resistant, peer-to-peer communication. Anonymous connections are achieved by end-to-end encrypting the user's traffic & sending it through relays.
Freenet
Freenet is a p2p platform for censorship-resistant communication. It uses a decentralized distributed data store to transfer information, and has a suite of free software for publishing and communicating on the Web without fear of censorship.
