Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing blockchain-based data authorization. One of the methods includes receiving, by a blockchain node, a data acquisition transaction submitted by a data user for obtaining target data possessed by a data owner, determining, by the blockchain node, that the data user has obtained authorization of the target data, and executing, by the blockchain node, a smart contract invoked by the data acquisition transaction to provide one or more of the target data and a computational result of one or more predetermined computational operations performed based on the target data to the data user.
