Free Haven Project
The Free Haven Project was formed in 1999 by a group of students with the aim to develop a secure, decentralized system of data storage. The group’s work led to a collaboration with the to develop , funded by .

Distributed anonymous storage system
The Project’s early work focused on an anonymous storage system, Free Haven, which was designed to ensure the privacy and security of both readers and publishers. It contrasts Free Haven to anonymous publishing services to emphasize persistence rather than accessibility. Free Haven is a distributed peer-to-peer system designed to create a “servnet” consisting “servnet nodes” which each hold fragments (“shares”) of documents, divided using Rabin’s Information dispersal algorithm such that the publisher or file contents cannot be determined by any one piece. The shares are stored on the servnet along with a unique . To recover and recreate the file, a client broadcasts the public key to find fragments, which are sent to the client along anonymous routes. For greater security, Free Haven periodically moves the location of shares between nodes.
Its function is similar to Freenet but with greater focus on persistence to ensure unpopular files do not disappear. The mechanisms that enable this persistence, however, are also the cause of some problems with inefficiency. A referral- or recommendation-based “metatrust” built into the servnet attempts to ensure reciprocity and information value by holding node operators accountable. Although nodes remain pseudonymous, communication is facilitated between operators through .
Work with Tor
Tor was developed to by the US Naval Research Laboratory and the Free Haven Project to secure government communications, with initial funding from the US and DARPA. Tor was deployed in 2003, as their third generation of deployed onion routing designs.<ref name=”ieee”/> In 2005, the provided additional funding to the Free Haven Project.<ref name=”ieee”/> In 2006, the Tor Project was incorporated as a non-profit organization.<ref name=”ieee”/>
