Each square is a bitcoin address (like a public key)<p>Each graph component is a transaction. The components appear as transactions are broadcast into the bitcoin P2P network (but before they are verified and committed to the blockchain)<p>Coin ownership flows from green to red (yellow is in/out: I pay you and take some change back)<p>When the output of one transaction becomes an input for a new transaction, the components are pulled together<p>This gives you a sense of how money is changing hands in the global bitcoin economy
