In cloud computing environments, accounting data faces severe challenges such as tampering, loss, and verification difficulties.Traditional centralised auditing solutions carry single-point-of-failure risks and suffer from inefficient verification processes.To address this, this paper proposes a smart accounting data integrity assurance system that synergises blockchain and cloud computing.The system leverages blockchain's immutability to construct a distributed auditing framework and employs optimised cryptographic algorithms to achieve efficient data verification in the cloud.Experiments on the public university of California Irvine dataset demonstrate that compared to traditional approaches, this system accelerates data verification by approximately 30% while keeping storage overhead below 15%.It effectively resolves the core conflict between trustworthy storage and efficient verification for cloud accounting data, providing modern enterprises with reliable data security assurance.
