BLOCKCHAIN-BASED DATA VERIFICATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE

摘要

One or more implementations of the present specification relate to data verification methods and apparatuses, and electronic devices. A data identifier of target data published by a data provider in a blockchain is obtained, by a verification client device, wherein the data identifier indicates a storage location of the target data in the blockchain. It is determined that the target data is stored in the blockchain based on the data identifier. In response, the target data is obtained, by the verification client device, from the storage location indicated by the data identifier, wherein the target data stored in the blockchain includes verification information to authenticate of the target data. The obtained target data is authenticated, by the verification client device, based on the verification information. A verification result is displayed to a data verifier of the verification client device.
