To attain independent verification of the chain of ownership each network node stores its own copy of the blockchain.68 About every 10 minutes, a new group of approved transactions, referred to as a block, is created, added to the blockchain, and quickly published to each of nodes, without requiring central oversight.
A conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, however, 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 consumer designates each speech and the amount of bitcoin being sent to this address in an output. To prevent double spending, each input has to consult with a prior unspent output in the blockchain.69 The usage of numerous inputs corresponds to the usage of numerous coins in a money transaction.
As in a cash transaction, the sum of inputs (coins used to pay) can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer.69 Any input satoshis not accounted for in the transaction outputs turn into the transaction fee.69.

However, the reverse, computing the personal key of a given bitcoin address, is mathematically unfeasible.
