P2p guardian not updating
The most fundamental change is support for darknet operation.Version 0.7 offered two modes of operation: a mode in which it connects only to friends, and an opennet-mode in which it connects to any other Freenet user. When a user switches to pure darknet operation, Freenet becomes very difficult to detect from the outside.The simplest is via FProxy, which is integrated with the node software and provides a web interface to content on the network.Using FProxy, a user can browse freesites (websites that use normal HTML and related tools, but whose content is stored within Freenet rather than on a traditional web server).Every node on the Freenet network contributes storage space to hold files and bandwidth that it uses to route requests from its peers.As a direct result of the anonymity requirements, the node requesting content does not normally connect directly to the node that has it; instead, the request is routed across several intermediaries, none of which know which node made the request or which one had it.Freenet attempts to protect the anonymity of both people inserting data into the network (uploading) and those retrieving data from the network (downloading).Unlike file sharing systems, there is no need for the uploader to remain on the network after uploading a file or group of files.
This problem was solved by making Freenet compatible with Open JDK, a free and open source implementation of the Java Platform.
These include reduced memory usage, faster insert and retrieval of content, significant improvements to the FProxy web interface used for browsing freesites, and a large number of smaller bugfixes, performance enhancements, and usability improvements.
Version 0.7.5 also shipped with a new version of the Windows installer.
Ian Clarke's resulting unpublished report "A distributed decentralized information storage and retrieval system" (1999) provided foundation for the seminal paper written in collaboration with other researchers, "Freenet: A Distributed Anonymous Information Storage and Retrieval System" (2001).
Researchers suggested that Freenet can provide anonymity on the Internet by storing small encrypted snippets of content distributed on the computers of its users and connecting only through intermediate computers which pass on requests for content and sending them back without knowing the contents of the full file, similar to how routers on the Internet route packets without knowing anything about files—except Freenet has caching, a layer of strong encryption, and no reliance on centralized structures.
