Bitcoin transactions are immutable, meaning once a transaction is confirmed, it cannot be reversed.

Bitcoin transactions are immutable, meaning once they are confirmed, they cannot be reversed. This is an attractive feature of Bitcoin, as it allows users to complete transactions with confidence. For example, if someone is buying a product online, they can rest assured that their transaction has been recorded and can not be reversed. This also ensures that merchants are protected from chargebacks, which can be very costly for them.

The immutability of Bitcoin transactions also plays a role in maintaining the integrity of the Bitcoin network. By ensuring that transactions are irreversible, it prevents double spending and protects from malicious attacks. This is one of the main reasons why Bitcoin has become so popular and widely used.
