Network nodes can validate transactions, add them for their own copy of this ledger, and then broadcast these ledger additions to additional nodes. To achieve independent verification of this chain of ownership every network node stores its own copy of the blockchain.68 About every 10 minutes, a new group of accepted transactions, referred to as a block, is created, added to the blockchain, and immediately published to all nodes, without requiring central supervision.
A conventional ledger records that the transfers of real invoices or promissory notes which exist apart from it, but the blockchain is the only location that bitcoins can be said to exist in the form 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 user designates each address and the amount of bitcoin being sent to that speech in an output.
