BLOCKCHAIN-BASED DATA VERIFICATION METHOD AND APPARATUS

摘要

The present application relates to the technical field of blockchains, and provided in the embodiments of the present application are a blockchain-based data verification method and apparatus. The method comprises: acquiring a request issued by a demander node on a blockchain, the request carrying encrypted data that contains warehouse receipt information; acquiring zero-knowledge evidence of participant nodes associated with the warehouse receipt information on the blockchain, the participant nodes comprising logistics nodes, warehouse nodes, and producer nodes; and performing 3D zero-knowledge proof on the encrypted data on the basis of the zero-knowledge evidence, and verifying the authenticity of the warehouse receipt information to obtain a verification resu and publishing the verification result to the blockchain for storage. The technical solution provided in the embodiments of the present application may solve the problem in the prior art of the authenticity of warehouse receipt data being difficult to verify.
