Chain history immutability means that once transaction data is recorded on a blockchain, it cannot be changed or removed. This characteristic ensures the integrity and permanence of all entries on the distributed ledger. Each block is cryptographically linked to the previous one, making any alteration practically impossible without detection.
Context
Chain history immutability is a fundamental security property central to the trustworthiness of blockchain networks and digital assets. Its importance is consistently highlighted in news concerning data integrity, auditability, and the prevention of fraudulent activities. Regulatory bodies and enterprises assess this feature for compliance and secure record-keeping applications.
