Definition ∞ A quantum randomness beacon is a system that publicly broadcasts unpredictable random numbers generated from quantum processes. This beacon uses genuine quantum phenomena, such as photon polarization or radioactive decay, to produce sequences of bits that are inherently unpredictable and verifiable. It provides a shared, unbiased source of randomness that multiple parties can independently access and verify for integrity. Such systems are critical for applications requiring strong, auditable randomness.
Context ∞ Quantum randomness beacons hold considerable promise for enhancing the security and fairness of digital asset protocols, particularly for cryptographic key generation, smart contract execution, and decentralized gaming. News reports often highlight efforts to deploy and standardize these beacons globally to provide a robust public source of entropy. The verifiable nature of quantum randomness offers a superior alternative to pseudo-random number generators.
