I2P (The Invisible Internet Project) is an anonymous overlay network - a network within a network. It protects communication from dragnet surveillance methods and monitoring by third parties such as ISPs.
I2P is used by many people who care about their privacy: activists, oppressed people, 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.
