Coinbase said on Tuesday it had added four national security experts to its global advisory council as the cryptocurrency industry comes under intense regulatory scrutiny following the collapse of Sam Bankman-Fried’s FTX. Mark Esper, Stephanie Murphy, Frances Townsend and David Urban are joining the council, which advises the company’s executive leadership team. Esper is a former U.S. defense secretary and Murphy is a former national security specialist for the defense department. Townsend has served as Counterterrorism and Homeland Security adviser to former President George W. Bush, while Urban was managing director at BRG Group, overseeing the corporate affairs of ByteDance. Coinbase said the new additions will help its council examine the consequences of regulatory uncertainty for crypto in the United States, including long-term economic and national security impacts.
