Integrity protection refers to measures that ensure the accuracy and reliability of data within a blockchain or cryptocurrency system. This involves maintaining data consistency and preventing unauthorized alterations.One of the primary mechanisms for integrity protection is cryptographic hashing. Each block in a blockchain contains a unique hash generated from its data and the hash of the previous block. This linking creates a secure chain, so that any change in one block alters its hash and breaks the chain’s integrity, signaling tampering.Consensus mechanisms, such as proof of work or proof of stake, also play a vital role. They require participants to validate transactions and maintain the network’s security. This collective agreement safeguards against fraudulent activities and ensures that the data recorded in the blockchain is accurate.Additionally, using digital signatures allows users to verify their identities and ensure that transactions are genuine. Together, these components create a secure environment that protects against manipulation and builds trust among users.
