Quantum random number distribution and verification scheme with blockchain integration

Abstract： There is a demand for true random numbers in applications that require high randomness and security. To address this, this paper proposes a quantum random number distribution and verification scheme that combines blockchain technology. The scheme utilizes a quantum random number generator to obtain true random numbers, which are stored on a cloud platform. By verifying users' aggregated signatures, corresponding quantum random numbers are allocated and the allocation records are uploaded to the blockchain. Distributed storage services are used to enable users to query and download the quantum random numbers. By integrating blockchain technology, users can trace and verify the distribution results, effectively enhancing the security and consistency of quantum random number distribution. This scheme solves the challenge of users obtaining true random numbers and provides a solution for scenarios where multiple users need to obtain the same true random numbers.
