An interesting article about how the illegal drugs has moved to the Internet. Using technologies like Bitcoin and TOR you can have an almost anonymous transaction of illegal items. But as Jeff Garzik (a core developer of the Bitcoin project) says:
He explains that because all Bitcoin transactions are recorded in a public log, though the identities of all the parties are anonymous, law enforcement could use sophisticated network analysis techniques to parse the transaction flow and track down individual Bitcoin users.
“Attempting major illicit transactions with bitcoin, given existing statistical analysis techniques deployed in the field by law enforcement, is pretty damned dumb,” he says.
