Block chain integrity verification method based on EPC global network

The invention discloses a block chain integrity verification method based on an EPC global network, relates to the technical field of EPC global networks, and the method comprises the following steps:each data owner uploads ProductInfo information and VerifyInfo information owned by the data owner to an EPCDS, and uploads RegistInfo of the data owner to a block chain; the EPCDS acquires uploadeddata to establish an index for a user to inquire, and returns verification information VO to the user while returning an inquiry result; and the user initiates a query to the EPCDS to obtain a query result and corresponding verification information VO. According to the invention, the product information is stored in the blockchain platform to provide verification of the query result for the user;and meanwhile, a batch number field is newly added to the product information to index the data, so that the storage overhead is reduced while the data uploading efficiency is improved, and the security privacy problem caused b
