For author David Gerard, whose books Attack of the 50 Foot Blockchain and Libra Shrugged investigate the role cryptocurrencies play in the financial system, what these projects lack is the key element the Bahamian one had: a pressing reason for a digital currency to exist. “I like the Bahamas’ digital currency because they started from the position of ‘we have a problem, how do we solve it’,” he says. “Their problem was that the outer islands didn’t have good banking access so the central bank stepped in. It’s supplying a form of money that can be used in those islands and can be used offline. They made it possible to transmit small amounts by phone so it’s just like handing someone a five-dollar note. If you look at the European Central Bank, they are not solving a problem.”
