Freenet is a decentralized, censorship-resistant distributed data store originally designed by Ian Clarke. Freenet aims to provide freedom of speech through a peer-to-peer network with strong protection of anonymity; as part of supporting its users' freedom, Freenet is free and open source software. Freenet works by pooling the contributed bandwidth and storage space of member computers to allow users to anonymously publish or retrieve various kinds of information. Freenet has been under continuous development since 2000; a version 1.0 has not yet been released but current builds are functionally usable
The Freenet file sharing network stores documents and allows them to be retrieved later by an associated key, as is now possible with protocols such as HTTP. The network is designed to be highly survivable, with all internal processes completely anonymized and decentralized across the network. The system has no central servers and is not subject to the control of any one individual or organization. Even the designers of Freenet do not have any control over the overall system. The stored information is encrypted and replicated across participating computers around the world, which are anonymized and intended to be many and continuously-changing. It is theoretically difficult for anyone to find out which participants are hosting a given file, since the contents of each file are encrypted, and may be broken into pieces that are distributed over many different computers. Due to the nature of encryption it is, by mathematical proof, highly impractical for a participant to view files hosted on his or her own system.
