Adrian Chen goes undercover to find out about the online site Silk Road:
Through a combination of anonymity technology and a sophisticated user-feedback system, Silk Road makes buying and selling illegal drugs as easy as buying used electronics—and seemingly as safe. It's Amazon—if Amazon sold mind-altering chemicals.
… Sellers feel comfortable openly trading hardcore drugs because the real identities of those involved in Silk Road transactions are utterly obscured. If the authorities wanted to ID Silk Road's users with computer forensics, they'd have nowhere to look. TOR masks a user's tracks on the site. The site urges sellers to "creatively disguise" their shipments and vacuum seal any drugs that could be detected through smell. As for transactions, Silk Road doesn't accept credit cards, PayPal , or any other form of payment that can be traced or blocked. The only money good here is Bitcoins. Bitcoins have been called a "crypto-currency," the online equivalent of a brown paper bag of cash.
