TOMAS JIRIKOVSKY got in way over his head. In 2013 the amateur programmer set up a dark-web market for illegal drug sales. He soon landed in prison. Upon release in 2021 he demanded his gear, which contained lots of cryptocurrency. The case stalled in court, and in March Mr Jirikovsky quietly struck a deal: in exchange for his drives, he would donate 468 bitcoins (currently worth about $49m) to the government.
