The Hidden Wiki is a censorship-resistant wiki operating as a Tor hidden service that anyone can anonymously edit. The main page serves as a directory of links to other .onion sites.
As a hidden service, The Hidden Wiki operates through the .onion pseudo top-level domain which can be accessed only by using Tor or a Tor gateway. Its main page provides a community-maintained link directory to other hidden services, including links to money laundering, contract killing, cyber-attacks for hire, contraband chemicals, and bomb making. The rest of the wiki is essentially uncensored and offers links to sites hosting child abuse images.
