About
API3 partnered with the Australian National University (ANU) Quantum Optics Group to launch API3 QRNG in May 2022, the first true random number generator for smart contracts. It uses quantum vacuum fluctuations measured through balanced homodyne detection. ANU's quantum random numbers are generated from electromagnetic field vacuum fluctuations at all frequencies, providing ultra-high bandwidth and truly unpredictable randomness rather than the output of pseudo-random generators. API3 QRNG is free to use, requiring only gas fees, and is available on 13 blockchain platforms including Polygon, Avalanche, Fantom, Metis, Moonbeam, and RSK. The system is hosted on Amazon Web Services with encrypted data transmission, and random numbers are destroyed after use. Applications include gaming, NFTs, lotteries, crypto wallet generation, and other blockchain uses that need quantum-level unpredictability. API3 QRNG addresses Web3 security demands by providing randomness based on quantum mechanics for decentralized applications, smart contracts, and cryptographic operations that require provably random numbers from natural quantum processes.
