THE first ever e-commerce transaction, conducted by students from Stanford and MIT in the early 1970s, involved the sale of a small quantity of marijuana. For decades afterwards, the online drugs trade was severely constrained by the ability of law enforcement to track IP addresses and the means of payment. The trickle of transactions threatened to become a flood with the emergence a few years ago of Silk Road, a drug-dealing site on the “dark net”. These e-depths cannot be reached through a normal browser but only with anonymising software called Tor. Buyers and sellers transact there pseudonymously in bitcoin, a crypto-currency.
Silk Road was shut last year with the arrest of Ross Ulbricht, the 29-year-old American whom investigators believe to be Dread Pirate Roberts, the site’s founder. Mr Ulbricht is due to stand trial in New York next January on charges that include computer hacking and money laundering.
