DATA PROCESSING METHOD AND APPARATUS BASED ON BLOCKCHAIN NETWORK, ELECTRONIC DEVICE, AND STORAGE MEDIUM

摘要

A data processing method is provided for an electronic device. The method includes obtaining from a target node a transaction request for off-chain data, parsing the transaction request to obtain a transaction parameter and a chain height parameter of the target node, querying, according to the chain height parameter of the target node, for the off-chain data, in response to determining the off-chain data is present in the data manager, sending the off-chain data to the target node, and in response to determining the off-chain data is absent in the data manager, obtaining the off-chain data from a data source according to a type of the target node.
