Imagine an information exchange into which all requirements for all imaginable goods and services are stored and available to all those who care to access it. Imagine an encrypted electronic card that identifies you with your fingerprint—dna if you care—and automatically credits you when you earn and debits you when you spend. Imagine a world of totally anonymous dealings in money for you, no one knowing what you earn and spend. Imagine a world without currency notes. Imagine a world without transaction costs, income-taxes and inflation. That is the power of enabling a costless exchange for goods and services that spreads across the world.
