The bitcoin blockchain is a public ledger that records bitcoin transactions.67 It is implemented as a chain of blocks, each block containing a hash of the prior block up to the genesis blocka of this chain. A network of communicating nodes running bitcoin program maintains the blockchain.31:215219 Transactions of the form payer X sends Y bitcoins into payee Z are broadcast for this network using readily available software applications. .

Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to additional 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, referred to as a block, is created, added to the blockchain, and quickly published to all nodes, without requiring central oversight.
A conventional ledger documents 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 a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to this speech in an outcome. To prevent double spending, each input must consult with some prior unspent output in the blockchain.69 The usage of multiple inputs corresponds to the use of numerous coins in a cash transaction.
As in a cash transaction, the sum of inputs (coins utilized to cover ) can exceed the intended sum of payments. In such a circumstance, an additional output signal is utilized, returning the change back to the payer.69 Any input satoshis not accounted for in the transaction outputs become the transaction fee.69.
Though transaction fees are optional, miners can choose which transactions to process and prioritize the ones that pay high fees.69 Miners may select transactions dependent on the commission paid relative to their storage size, not the total amount of money paid as a commission. These fees are generally measured in satoshis each byte (sat/b).

Simplified chain of ownership as exemplified in the Bitcoin whitepaper.5 In practice, a transaction can have more than one input and more than one output.69
In the blockchain, bitcoins are registered to bitcoin addresses. Creating a bitcoin address requires nothing more than picking out a random valid private key and computing the corresponding bitcoin address. This computation can be done in a split second. But the reverse, computing the personal key of a given bitcoin address, is mathematically unfeasible.

In addition, the number of legitimate private keys is so immense it is extremely unlikely someone will calculate a key-pair that's already in use and contains funds. The vast number of legitimate private keys makes it unfeasible that brute force could pop over to these guys be used to undermine a private key. To be able to spend their bitcoins, the owner has to know the corresponding private key and digitally sign the transaction.
