Tracking Markets on the Darknet
A researcher using the pseudonym Gwern Branwen has published a dataset containing detailed information about English-language darknet markets operating between 2013 and 2015. Darknet markets, like the infamous Silk Road, are hidden websites that allow users to obtain drugs or other illicit goods or services using bitcoins or other cryptocurrencies. The dataset contains information such as vendor pages, images, and customer feedback collected daily on 89 of these markets, as well as 37 related forums.
