Network nodes can affirm transactions, add them to their own copy of this ledger, and then broadcast these ledger additions to other nodes. To attain independent verification of this chain of ownership every network node stores its own copy of the blockchain.68 About every 10 minutes, a new set of approved transactions, called a block, is made, added to the blockchain, and quickly published to each of nodes, without requiring central supervision.

A conventional ledger records that the transfers of actual 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 presses. When an individual sends bitcoins, the user designates each speech and the amount of bitcoin being sent to this address in an output. To prevent double spending, each input must refer to a 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 used to pay) can exceed the intended amount of payments.
