Abstract: Provided are a blockchain-based data verification method and apparatus, a device, and a storage medium, relating to the field of computer technology, for example, a blockchain technology, and applicable to cloud computing and cloud services. The solution includes acquiring a data verification transaction request initiated by a data owner; generating a response signature value in the current verification round according to the data verification transaction request; and sending the response signature value to a blockchain network. The response signature value is configured to instruct the blockchain network to verify whether the to-be-verified data block is stored in a data storer.
