Bitcoin is just the beginning. Ether coin is showing where this will lead. Counterparty and Colored Coins are doing the same. Bitcoin transfers bitcoins, a simple quantity, or number. The others are attempting to transfer ownership, kinda like bearer bonds. Once the idea of bearer bonds in the form of contractual ownership of any property, is worked into a blockchain idea in a practical way, it will be all over for banks, lawyers, and most of the government.
