Monero

For Monero's implementation of I2P, see Kovri. For a comparison of I2P to Tor, read the Comparison page.

The Basics

From Java I2P:

The I2P network provides strong privacy protections for communication over the Internet. Many activities that would risk your privacy on the public Internet can be conducted anonymously inside I2P.

In-depth information

From Java I2P:

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. Its anonymity will get stronger as the size of the network increases and with ongoing academic review.
