People on the forum have asked how anyone can know a bitcoin address belongs to SR. Here's your answer: I received assistance from Sara Meiklejohn, a graduate student at the University of California, San Diego who's been analyzing the role of bitcoin and anonymity on the Silk Road. Meiklejohn confirmed that the bitcoin wallet linked to in Fly's forum thread was indeed used to deposit two bitcoins into a purse controlled by anonymous individuals who help manage commerce on the Silk Road. Meiklejohn and fellow researcher Damon McCoy, an assistant professor of computer science at George Mason University, have been mapping out a network of bitcoin wallets that are used exclusively by the curators of the Silk Road. If you wish to transact with merchants on the Silk Road, you need to fund your account with bitcoins. The act of adding credits appears to be handled by a small number of bitcoin purses. "All Silk Road purchases are handled internally by Silk Road, which means money trades hands from the Silk Road account of the buyer to the Silk Road account of the seller," explained Meiklejohn, author of the paper, A Fistful of Bitcoins: Characterizing Payments Among Men with No Names, to be released in October 2013 at the ACM Internet Measurement Conference in Barcelona, Spain. "These accounts aren't visible on the bitcoin network though, so the only thing we can even hope to see by looking at the public transactions is when money goes into and comes out of the set of addresses that represent the collective account balances of all silk road users," Meiklejohn wrote in an email to KrebsOnSecurity. "By manually tagging a handful of silk road addresses (via direct interaction) and then bootstrapping using the heuristic I described to label many more (around 250,000 in total), we are able to achieve this second goal by identifying addresses in the network that are 'owned' by silk road."
