The blockchain is a digital ledger that records all transactions made with a cryptocurrency like Bitcoin, organized into blocks linked together in a chain.
Each block in the blockchain contains a list of transactions and, once added to the chain, the information becomes permanent and unalterable, ensuring a secure and transparent method to track digital currency movement.
Furthermore, each block references its predecessor through a cryptographic hash (a digital fingerprint), forming an unbreakable and secure chain.
This method of linking blocks guarantees the integrity of the transaction history, as it prevents any alterations to the data after it has been added to a block, maintaining the blockchain’s reliability and security.
