Simon Dixon (see video below), CEO & Co-Founder of BnkToTheFuture.com, says the inventions behind bitcoin are significant. The first is a system whereby all financial transactions are reported into a transparent ledger. This is in contrast to a bank that maintains a private ledger. Bitcoin is also the largest computer network in the world and is powered by hundreds of thousands of computers around the world creating the largest super computer in the world. Finally, bitcoin created a system in how money is created in a transparent way where you would know the monetary policy and the money (fiat currency) supply at any moment in time. In contrast, traditional Central Banks adjust their policies of how money is created over time.
