A conventional ledger records the transfers of real bills or promissory notes that exist apart from it, but the blockchain is the only place that bitcoins can be said to exist in the kind of unspent outputs of transactions.3:ch. 5.
Transactions are defined using a Forth-like scripting language.3:ch. 5 Transactions consist of one or more inputs and one or more outputs. When a user sends bitcoins, the consumer designates each speech and the amount of bitcoin being sent to this speech in an output. To prevent double spending, every input must consult with some previous unspent output in the blockchain.69 The usage of multiple inputs corresponds to the usage of multiple coins in a money transaction.
As in a cash transaction, the amount of inputs (coins utilized to cover ) can exceed the intended sum of payments. In this case, an additional output is used, returning the change back to the payer.69 Any input satoshis not accounted for in the transaction outputs become the transaction fee.69.
