The F.B.I., after months of sleuthing, claimed that Ulbricht was Dread Pirate Roberts, the mastermind behind the notorious Silk Road, an online black market for drugs and other illicit activity. Since January of 2011, the Silk Road had seen more than $1.2 billion dollars of business, and become a place where, using Bitcoin and highly encrypted servers, anyone with an Internet connection could purchase, say, "5G [of] Pure Cocaine Cristal," ordering online and receiving drugs swiftly by mail. The business made the Dread Pirate Roberts (D.P.R.) a cyber-millionaire, and, he wrote, hopefully made drug-trafficking safer for all parties. D.P.R. described the site as a way to "abolish the use of coercion," posting about Austrian economics and what state regulations and taxes do to markets. In many ways, the Silk Road was a Randian economic model taken to its logical extreme.
