This glossary contains definitions and explanation of some common terminology and phrases you may come across while exploring Freenet.
Content Hash Key (CHK)
All files in Freenet are requested using one of 4 types of keys. Content hash keys are commonly used for files that are not going to change, such as movies, music, and file archives. An example key is “CHK@yA6iTzVVt4cgY3P5xXiWD1qH-JotT48kVvfvCCzjgBQ,F3sPxJsMlfU9e~CM3xXwCzTUmr81QVXw98150g8014A,AAIC--8/GPLv3.txt”. See Content Hash Key
A Darknet is a private or semi-private network consisting of Freenet nodes run by a user and other users they know and trust (such as friends). The purpose of a Darknet is to limit or even remove contact between your node and those run by strangers, thus improving your anonymity and the security of the network. See Darknet, Opennet, Node reference
Fred is an acronym for Freenet REference Daemon. Fred is the core of Freenet. It manages all of the nodes on the Freenet network, and provides important functionality for many parts of Freenet. See Fred
Freesites are static websites that reside inside the Freenet network, and are only accessible through the Freenet network. Browsing Freesites is a popular activity when using Freenet.
Freetalk is a plugin that provides a forum-like method of communication between Freenet users. It is currently the preferred method of communication within Freenet. See Freetalk
Frost is an external application that provides usenet style communication and file sharing using the Freenet network. While its popularity has decreased due to spam and DoS attacks in certain boards, some boards are still thriving. See Frost
FProxy is the name of the web interface used to browse Freenet. See FProxy.
Keyword Signed Key (KSK)
All files in Freenet are requested using one of 4 types of keys. Keyword signed keys are a more easily read key than the other types as they are not randomly generated. A side effect of this is that they can easily be spammed or spoofed, and are thus not commonly used. An example is "KSK@atextfile.txt". See Keyword Signed Key
abs((my node location) - (peer node location))
Signed Subspace Key (SSK)
All files in Freenet are requested using one of 4 types of keys. Signed subspace keys are used to link to frequently updated content while allowing only the original content provider to alter it. See Signed Subspace Key, Updateable Subspace Key
Sone is a plugin that provides social-network style communication over the Freenet network. See Sone
Updateable Subspace Key (USK)
All files in Freenet are requested using one of 4 types of keys. Updateable subspace keys are essentially wrappers around signed subspace keys that allow nodes to retrieve the latest version of the objects in question. This is useful for things such as Freesites which are updated frequently. See Updateable Subspace Key, Signed Subspace Key
An Opennet is the primary means of establishing connections between your node, and other nodes on the Freenet network. When enabled, your node will contact a seed node and retrieve a list of other Opennet nodes to connect to which will then provide its own list of nodes to connect to, which will provide its own list, and so on. This process happens continually, without the need for intervention, while the node is running. See Darknet, Opennet
Web of Trust
The Web of Trust, commonly abbreviated WoT, is a plugin that provides a decentralized method for rating users with the primary intention providing the fundamental building blocks for applications that depend on user-to-user interactions such as the Freetalk plugin while limiting spam and other disruptive activities.
