According to an exclusive report by Time, Russia helped Venezuelan officials create the world's first state-backed cryptocurrency to skirt U.S. sanctions. The cryptocurrency was launched in late February and was banned by the Trump administration earlier this week. From the report: The new cryptocurrency, a form of digital cash that is supposedly linked to the value of Venezuela's oil reserves, was launched on Feb. 20 during a ceremony in the presidential palace in Caracas. Nicolas Maduro, the socialist leader of Venezuela, declared that it would serve as a kind of "kryptonite" against the power of the U.S government, which he sarcastically referred to as "Superman." Sitting in the front row at that ceremony were two of Maduro's Russian advisers, Denis Druzhkov and Fyodor Bogorodsky, whom the President thanked for aiding his fight against American "imperialism." Both men have ties to major Russian banks and billionaires close to the Kremlin. But they were not the most senior Russians involved. According to an executive at a Russian state bank who deals with cryptocurrencies, senior advisers to the Kremlin have overseen the effort in Venezuela, and President Vladimir Putin signed off on it last year. "People close to Putin, they told him this is how to avoid the sanctions," says the executive, who spoke to TIME on condition of anonymity. "This is how the whole thing started."
