I2P is an anonymous network exposing a simple layer that applications can use to anonymously and securely send messages to each other. The network itself is strictly message based (ala IP), but there is a library available to allow reliable streaming communication on top of it (ala TCP). All communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points ("destinations") are cryptographic identifiers (essentially a pair of public keys).
Reviewing 0.6.4 (Oct 22, 2008)
A decentralized anonymizing layer built on top of the regular internet.
It has a gnutella client, i2Phex, a emule like kademlia-client called iMule.
Very useful and has a very helpful dev- team.
Reviewing 0.6.1.24 (Jul 31, 2006)
Not as secure as you believe.
Real security is when you do not need to encrypt anymore, due to the high security level you already have =).
look at the OFF P2P System
Reviewing 0.6.1.18 (May 11, 2006)
Very interesting network in its early stages. Has support for Gnutella and Bittorrent so far over I2P, with more to come. Definately worth checking out :)
Reviewing 0.6.1.18 (May 10, 2006)
This is just an early cut at a new platform for programmers to write applications with. By itself, an end-user can't really do anything special. Like all other "anonymous" networking solutions, it's not truly 100% anonymous, but when you try to summarize and simplify, people will get the impression that it's actually anonymous. I don't think we need another such solution, especially one which is going to require special app support. Projects like Tor show more promise.
