On Tuesday night, President Donald Trump issued a pardon to Ross Ulbricht, who ran the dark web marketplace Silk Road under the pseudonym “Dread Pirate Roberts.” Ulbricht has been serving a life sentence without parole since 2015, when he was convicted of multiple charges, including the distribution of narcotics.

Donald Trump pardoned the creator of the world’s first dark-web drug market, who is now a libertarian cause célèbre in some parts of the crypto community.

Ulbricht was sentenced to life in prison in 2015 on charges related to his website, where users could buy and sell drugs and other illegal goods with bitcoin.
