Sequential Hashing

Definition ∞ Sequential Hashing is a cryptographic process where data blocks are linked together by computing a hash of the current block that includes the hash of the previous block. This creates an ordered chain where each new entry cryptographically depends on its predecessor. This method ensures the integrity and immutability of the data sequence, making any alteration easily detectable.
Context ∞ Sequential Hashing is a foundational concept in blockchain technology, directly underpinning the security and tamper-resistance of distributed ledgers. News often references this technique when explaining how transactions are added to the chain and how the network maintains its verifiable history. The cryptographic linkage provided by sequential hashing is critical for preventing fraud and maintaining trust in decentralized systems.
