Definition ∞ Cuckoo hashing is a collision resolution strategy used in hash tables, employing multiple hash functions to place items. When a collision occurs, an existing item may be moved and rehashed to another location using an alternative hash function. This method aims to maintain constant-time average-case lookup performance. It finds application in various data storage and retrieval systems requiring high efficiency.
Context ∞ While not exclusively a crypto term, cuckoo hashing principles are relevant in certain cryptographic constructions and data structures within blockchain technology for efficient data management. Discussions might relate to its use in specific proof systems or data indexing mechanisms for performance optimization. Future adaptations could see it applied in resource-constrained environments or for enhancing privacy-preserving protocols.
