Id: paper .tex 1654 2012-11-28 17:04:37 Z nicolasc Abstract We perform a comprehensive measurement analysis of Silk Road, an anonymous, international on- line marketplac e that operate s as a Tor hidden service and uses Bitcoin as its exchange currenc y. We gather and analyze data over eight months between the end of 2011 and 2012, including daily crawls of the marketplace for nearl y six months in 2012. We obtain a detaile d picture of the type of goods being sold on Silk Road, and of the revenues ma de both by sellers and Silk Road operato rs. Through examining over 24,400 separate items sold on the site, we show that Silk Road is overwhelmingly used as a market for controlled subs tances and narcotics , and that most items sold are av ailable for less than three weeks. The majority of sellers disappears with in roughly three months of their arriva l, but a core of 112 sellers has been present througho ut our measurement interval. We evaluate the total revenue made by all sellers, from public listings, to slightly over USD 1.2 million per month; this corresponds to about USD 92,000 per month in commissions for the Silk Road operators. We further show that the marketplace has been operating steadily, with daily sales and number of sellers overall increasing over our measurement interv al. We discu ss economic and policy implications of our analys is and results , including ethical considerations for future research in this area. Keywords: Online crime, anonymity, electronic commerce. 1
