The first Silk Road launched in 2011 and ultimately became a boon to the Bitcoin economy. Most of the products found on that site were cannabis or MDMA. Since it was shut down in 2013 – and its founder, Ross Ulbricht, given a lifetime sentence – other darknet marketplaces have appeared online.
In 2013, immediately following the fall of Silk Road I, Silk Road 2.0 opened for business. In December 2013, admins for that website were arrested and the site brought down. Silk Road 3.0 is operational. There’s no word on how long that might last. For other dark web options, check out the list of active marketplaces here. This option is illegal, and there is feverish debate among users about the safety of such dark net websites.
