Abstract
One or more embodiments of the present specification provide data retrieving and recording methods and apparatuses, and electronic devices. One method comprises: identifying, by a blockchain node in a blockchain network, a data retrieving and recording request for a smart contract, wherein the data retrieving and recording request is configured to trigger a data retrieving and recording operation on a target object in a data set comprised in the smart contract; and parsing, by the blockchain node and to generate a parsing result, metadata comprised in the smart contract, wherein the parsing performs instructions comprised in the smart contract, and wherein the parsing result indicates a storage field corresponding to the target object in the data set for implementing the data retrieving and recording operation on the storage field.
