FromThe Invisible Internet Project:I2P is an anonymous overlay network - a network within a network. It is intended to protect communication from dragnet surveillance and monitoring by third parties such as ISPs.
I2P is used by many people who care about their privacy: activists, oppressed people, journalists and whistleblowers, as well as the average person.
No network can be "perfectly anonymous". The continued goal of I2P is to make attacks more and more difficult to mount
