[Set up a Tor hidden service] [This site on Tor] [List of Tor sites] I2P is "an anonymous network layer (implemented as a Mix Network) that allows for censorship resistant, peer to peer communication. Anonymous connections are achieved by encrypting the user's traffic (by using end-to-end encryption), and sending it through a volunteer-run network of roughly 55,000 computers distributed around the world."
