Abstract
Embodiments of the present specification disclose methods, apparatuses, and devices for transferring data assets based on a blockchain. One method includes: obtaining usage demand information of a data requestor for using original data, wherein the usage demand information indicates a demand of the data requestor for performing computations based on the original data; sending a usage authorization request for the original data to a data owner of the original data based on a decentralized identifier (DID) corresponding to the original data; receiving confirmation information of the usage authorization request from the data owner; processing the original data based on the usage demand information to obtain a processing result; transmitting the processing result to the data requestor; and generating a verifiable claim (VC) for recording usage information of the original data.
