The Invisible Internet Project (I2P) is a garlic routing using overlay network and darknet that allows applications to send messages to each other pseudonymously and securely. Uses include anonymous Web surfing, chatting, blogging and file transfers. The software that implements this layer is called an I2P router and a computer running I2P is called an I2P node.

I2P focuses on providing strong anonymity and privacy through a decentralized network, making it ideal for users needing high security. In contrast, Anomos offers a more user-friendly experience with built-in features for messaging and file sharing, but sacrifices some anonymity and advanced functionalities.
