Virgil Griffith, an American citizen, was arrested Nov. 30 after speaking on blockchain solutions at the April 2019 Pyongyang Blockchain and Cryptocurrency Conference in North Korea. According to a United States Department of Justice (DOJ) press release,[1] Griffith spoke to roughly 100 attendees about ways blockchain technology could be used to move money and data around the globe undetected. DOJ charged Griffith with a violation of the International Emergency Economic Powers Act[2] for traveling to the DPRK and passing along information on blockchain solutions that could be used to evade US sanctions and launder money.
