Cryptographic Hash

Definition ∞ A cryptographic hash is a unique, fixed-size digital fingerprint of data. This mathematical function transforms arbitrary input data into a distinct, fixed-length output string, known as a hash value or message digest. Key properties include its deterministic nature, computational resistance to preimage attacks, and extreme sensitivity to even minor input alterations. Cryptographic hashes are essential for verifying data integrity and authenticity in digital systems without revealing the original data.
Context ∞ Cryptographic hashes form a fundamental security component in blockchain technology, ensuring the integrity and immutability of transaction records. Any modification to a block’s data would result in a different hash, immediately signaling tampering. The selection and ongoing security assessment of hash functions, such as those in the SHA family, remain crucial for the continued robustness of digital asset systems.
