The Darknet is the underground part of the internet that allows for anonymous ecommerce transactions. It uses the TOR network to hide server locations and identities. The Darknet functions as an illegal online marketplace, with the most prominent being Silk Road, selling illegal goods like an "illegal Amazon.com". Unless authorities are able to shut it down, the Darknet will likely continue growing over the next two years and could develop into multiple large illegal marketplaces that serve as the primary source for black market goods and services.
