Transaction data processing method, system and device based on Blockchain and storage medium

Abstract

The invention relates to the technical field of Blockchains, and discloses a transaction data processing method, system and device based on a Blockchain and a storage medium, and the method comprisesthe steps: enabling a business acceptance node on the Blockchain to receive first transaction data, and carrying out the format conversion of the first transaction data to obtain second transaction data; verifying the second transaction data by calling an intelligent contract to obtain a verification result; and generating summary information based on the verification result and the second transaction data, encrypting the second transaction data to obtain encrypted information, and executing Blockchaining operation on the encrypted information and the summary information. Through accessing each channel provider to the Blockchain and defining a unified data format on a service acceptance node accessed by each channel provider, transaction data generated by user subscription can be convertedinto a unified format and sent to the Blockchain for verification and storage, so that the IPO subscription process time is shortened, the user fund is prevented from being occupied for a long time,and the problem of data sensitivity among the channel providers can be solved.
