The accused mastermind behind the Silk Road underground website was sentenced on Friday to life in prison for orchestrating a scheme that enabled more than $200 million of anonymous online drug sales using the digital currency bitcoin.

Ross Ulbricht, 31, was sentenced by U.S. District Judge Katherine Forrest in Manhattan after a federal jury in February found him guilty of charges including distributing drugs through the Internet and conspiring to commit computer hacking and money laundering.

"What you did was unprecedented," Forrest said. "And in breaking that ground as the first person, you sit here as the defendant having to pay the consequences for that."
