The US needs a digital Dollar by Sean Worthington, the founder of CloudCoin and RAIDATech

It is clear that not all currencies are created equal and that digital currencies based on cryptography (e.g. Bitcoin), and currencies based on DNS (e.g. CloudCoin), have properties that give them an advantage over paper money.

CloudCoin, for example, allows us to send money anywhere in the world, at any time of day, in a split second, with no fees. That is something paper money cannot do.
