Tamper Resistance

Definition ∞ Tamper resistance refers to a system’s ability to withstand unauthorized modification, alteration, or interference. It ensures the integrity and authenticity of data or physical devices. In blockchain technology, tamper resistance is a fundamental property, achieved through cryptographic hashing and decentralized consensus mechanisms. Once recorded, data on a blockchain is exceptionally difficult to change, providing a high degree of security.
Context ∞ Tamper resistance is a core security feature often highlighted in crypto news when discussing the reliability and trustworthiness of blockchain networks. Reports frequently emphasize how this property makes blockchains suitable for immutable record-keeping, supply chain verification, and digital identity solutions. The robustness of a protocol’s tamper resistance is a critical factor in its perceived security and its potential for widespread adoption across various industries.
