Abstract

The embodiment of the invention provides a data verification method and device based on a block chain, and relates to the technical field of block chains, and the data verification method comprises the steps: obtaining a request issued by a demand side node on the block chain, and enabling the request to carry encrypted data containing warehouse receipt information; obtaining zero knowledge evidences of participant nodes associated with the warehouse receipt information on the block chain, wherein the participant nodes comprise logistics nodes, storage nodes and generator nodes; performing 3Dzero-knowledge proof on the encrypted data based on the zero-knowledge evidence, and verifying the authenticity of the warehouse receipt information to obtain a verification result; and publishing theverification result to the block chain for evidence storage. According to the technical scheme provided by the embodiment of the invention, the problem that the authenticity of warehouse receipt datais difficult to verify in the prior art can be solved.

Description

【Technical field】 [0001] The invention relates to the technical field of block chains, in particular to a data verification method and device based on block chains. 【Background technique】 [0002] In the blockchain, all data is encrypted and stored. Although data encrypted storage realizes safe data sharing, it will make it difficult to effectively verify the authenticity of the data. For example, using warehouse receipts for financing requires verification of the financing process. The authenticity of various warehouse receipt-related data and existing transaction data have a greater risk of artificial fraud, and it is difficult to verify the authenticity of warehouse receipt data. 【Content of invention】 [0003] In view of this, the embodiments of the present invention provide a blockchain-based data verification method and device to solve the problem in the prior art that the authenticity of warehouse receipt data is difficult to verify. [0004] In order to achieve th...
