I2P is an anonymity 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. All traffic is encrypted end to end.
Many applications are available that interface with I2P, including mail, peer-peer, IRC and others. I2P is available for all platforms. In simple words, I2P is a protocol used for an encrypted multi-proxy on the Internet.
