I2P
I2P is an anonymizing network to securely communicate
...In some cases people rely on the network when they need to be discrete or are doing sensitive work. I2P hides the server from the user and the user from the server. All I2P traffic is internal to the I2P network. Traffic inside I2P does not interact with the Internet directly. It is a layer on top of the Internet. It uses encrypted unidirectional tunnels between you and your peers. No one can see where traffic is coming from, where it is going, or what the contents are. Additionally, I2P offers resistance to pattern recognition and blocking by censors.
