Bitcoin transactions are recorded on a public ledger known as the blockchain. The blockchain is an immutable, distributed ledger that is managed by a network of computers. It stores a record of every transaction ever made with Bitcoin, ensuring that all transactions are accurate and secure.
The blockchain is an open and transparent system, meaning that anyone can view all the transactions that have taken place. This ensures that all transactions are recorded in a public and secure manner. The blockchain is also used to verify and validate transactions, as the network of computers must agree on the accuracy of the data before it is added to the blockchain.
The blockchain is an important part of the Bitcoin network, as it is the backbone of the system. It provides a secure and reliable way to store and transfer Bitcoin, and it also allows users to trust that the transactions they make will be secure and accurate.
