Each Bitcoin is divisible into a hundred millionth of a bitcoin called a satoshi. These tiny fractions of a bitcoin can be programmed to represent assets other than money . In this way the bitcoin blockchain can be used to verify transactions of all kinds of items without a need for a central authority. The bitcoin blockchain is a technological innovation that enables distributed consensus. People are able to come to agreement on what the state of this ledger should be and what it is. And that enables people to have trust without trusting any other party or person or institution. So anywhere people need to have trust where they need to be able to verify what is the true and correct state of something, that has an application to be put on the bitcoin blockchain.
