An independent Catalonia would likely have a national cryptocurrency.
The small but economically vital Catalonia region of Spain has declared its independence, but Madrid vows to keep the region a part of Spain. While governments and thought leaders around the world line up behind opposing sides, the would-be independent government is looking to use a national cryptocurrency and a Blockchain-based residency system.
According to a local newspaper in Spain, the Catalonian director of the digital office (called SmartCatalonia) has already visited Estonia on a number of occasions in order to understand their digital residency plans. Estonia famously made news when their plan for a national currency was harshly shot down by the European Central Bank President.
