Definition ∞ Tamper evident refers to a characteristic of a system or device that makes any attempt to alter or interfere with it readily apparent. This design principle ensures that unauthorized modifications leave a visible or detectable trace. In digital security, especially with blockchain, the immutability of records makes them inherently tamper evident. This property is crucial for maintaining data integrity and trust.
Context ∞ News about tamper-evident features often relates to supply chain management, digital identity, and the security of physical devices used in the crypto space. Blockchain’s cryptographic linking of blocks creates a tamper-evident ledger, where any alteration would break the chain’s integrity. This attribute is a fundamental advantage for applications requiring high levels of data trustworthiness and auditability.
