I2P is an open source project building an anonymous and/or pseudonymous virtual private 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 (a la IP), but there is a library available to allow reliable streaming communication on top of it (a la 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).

Although many of the developers had been a part of the IIP and Freenet communities, there are significant differences between their designs and concepts. IIP is an anonymous centralized IRC server, Freenet is a censorship resistant distributed data store, but I2P is an anonymous peer-to-peer distributed communication layer designed to run any traditional internet service (e.g. usenetUsenet or Unix User Network is a communications medium in which users read and post textual messages (called "articles") to a number of distributed newsgroups (incorrectly called bulletin boards because of their similarity for the unaware observer). The m, email, IRC, webhosting and http, telnetTelnet is a network protocol used on the Internet. IETF document STD 8 (aka and ) states: : The purpose of the TELNET Protocol is to provide a fairly general, bi-directional, eight- bit byte oriented communications facility. It is typically used to provid), as well as more traditional distributed applications (e.g. a distributed data store, a web proxy network using Squid cacheSquid is a popular open source Proxy server and web cache. It has a variety of uses, from speeding up a web server by caching repeated requests, to caching web, DNS, and other network lookups for a group of people sharing network resources. It is primaril, and DNS).
