Recurrent Randomness

Definition ∞ Recurrent Randomness refers to a sequence of random numbers that can be regenerated from a smaller seed or state. This concept is essential in cryptographic applications where unpredictable yet reproducible randomness is required. Unlike truly random numbers, recurrent randomness is pseudorandom, meaning it is generated by an algorithm but appears statistically random. Its reproducibility from a shared secret allows for verifiable random functions or common random beacons in decentralized systems.
Context ∞ Recurrent Randomness is a critical component for fair and unpredictable outcomes in blockchain-based gaming, lotteries, and decentralized autonomous organization (DAO) governance. Discussions involve ensuring the cryptographic security of seed generation and preventing manipulation of the random sequence. Future developments aim to build more robust and verifiable random functions that are resistant to collusion and predictive attacks.
