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.Anonymity is not a boolean - we are not trying to make something "perfectly anonymous", but instead are working at making attacks more and more expensive to mount. I2P alone is what could be called a "low latency mix network", and there are limits to the anonymity offered by such a system, but the applications on top of I2P, such as Syndie, I2P mail, and I2PSnark extend it to offer both additional functionality and protection. I2P is still a work in progress, and should only be used for testing or development purposes prior to the 1.0 release. Further releases beyond that will add support for more hostile adversaries.
