Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle. In the context of cryptocurrency, this means ensuring that transaction records and balances are correct and have not been altered or corrupted.One key feature that supports data integrity is blockchain technology. Each transaction is securely recorded in blocks, which are linked together in a chronological chain. Once information is added to the blockchain, it becomes practically immutable, making it difficult to change or delete past transactions without consensus from the network.Additionally, cryptographic techniques play a crucial role. They protect data from unauthorized access and ensure that transactions can only be verified by legitimate parties. This provides a high level of trust and accountability among users.In summary, data integrity is essential for maintaining the trustworthiness of transactions, ensuring that users can confidently engage with the system without concerns about manipulation or fraud. This foundational principle helps support the overall security and usability of cryptocurrencies.
