The dark web is known to have begun in 2000 with the release of Freenet, the thesis project of University of Edinburgh student Ian Clarke, who set out to create a "Distributed Decentralised Information Storage and Retrieval System." Clarke aimed to create a new way to anonymously communicate and share files online. That groundwork was the basis for the Tor Project, which was released in 2002 and launched a browser in 2008. With the creation of Tor, users could now browse the internet completely anonymously and explore sites that were deemed part of the "dark web."
Originally used by the United States Department of Defense to communicate anonymously, the dark web has now become a hub for users wishing to remain anonymous around the world. People use the dark web for both legal and illegal purposes. It uses a technology called "onion routing," which protects users from surveillance and tracking through a random path of encrypted servers. When users access a site through Tor, their information is routed through thousands of relay points that cover the user's tracks and make their browsing virtually impossible to trace.
