Abstract
A computer-implemented method includes: obtaining, by a blockchain node, an invoking request for a first smart contract based on receiving a data structure update transaction, where the transaction comprises an input parameter indicating an updated data structure. The updated data structure that is based on a computer programming language is obtained. The first smart contract is run, comprising: parsing the updated data structure and converting the updated data structure characterized by the computer programming language into updated metadata characterized by a definition description language. A second smart contract comprising pre-update metadata and data is invoked using the updated metadata as input parameters. The second smart contract is run, comprising: replacing the pre-update metadata with the updated metadata, parsing the updated metadata in the second smart contract, and updating a pre-update data structure of the data in the second smart contract based on a parsing result.
