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.
This research introduces Proof-of-Transit Timestamping, a novel cryptographic primitive enabling tamper-evident audit trails for Bitcoin across high-latency, intermittently-connected interplanetary links.
