Unode is a short form of underground node: a script or program that combines other programs for creating a decentralized anonymous encrypted communication network. Other programs include: Entropy, Mixmaster, GPG, NEWSPOST, plus Plugins for more.
Some of these scripts are used to forward email lists to the newsgroup alt.activism.underground. By doing this, activists can read important action alerts and other information without being included on the servers email lists that run the lists. Email headers are removed from these posts, as well as email addresses themselves are altered to help avoid spam.
Unix bash scripts are used because it is easy for other to alter or correct errors in the scripts, and because it is an easy way to try out new ideas. It is used as a rough draft, before the eventual move to stable binary programs.
