Block (Bitcoin Block)

Bitcoin blocks are permanent files on which recent Bitcoin transactions are recorded.

When one block is completed, then it's ready for the next block to record transaction histories. So...you will always have a record of what you paid (and to whom) that can’t be changed or removed.

The goal is to make it impossible for hackers to tamper with the data that has been recorded, and they can’t try and use the same Bitcoin for two different transactions.

So the next time you order a pizza through PizzaForCoins...or yellow cake uranium from Chad...you can rest assured the transaction has a permanent record.
