Problems solved by technology

[0002] At present, due to the characteristics of blockchain technology that cannot be tampered with and is decentralized, the application of data storage based on blockchain technology is becoming more and more extensive. Among them, the preset ciphertext is used for each business data to be uploaded In the form of storing business data in the blockchain, the business data stored in the blockchain includes: transaction hash, transaction type, block hash, Nonce string, etc. Therefore, the business directly read from the blockchain Data suffers from poor legibility

Abstract

One or more embodiments of the invention provide a service data uplink method and device, and the method comprises the steps: obtaining to-be-uplink service data generated for each service processingnode in a target service, wherein the to-be-uploaded service data comprises feature values corresponding to a plurality of service data fields; calling an intelligent contract deployed in the blockchain, and generating service data summary information corresponding to each service processing node based on the feature values corresponding to the plurality of service data fields and a preset summaryinformation field, wherein the preset abstract information field comprises a specified data field involved in a unified abstract data structure constructed for a plurality of service processing nodes; and storing the service data summary information generated for each service processing node and the corresponding to-be-uploaded service data into a block chain.

Description

technical field [0001] This document relates to the field of Internet technology, in particular to a method and device for uploading business data to the chain. Background technique [0002] At present, due to the characteristics of blockchain technology that cannot be tampered with and is decentralized, the application of data storage based on blockchain technology is becoming more and more extensive. Among them, the preset ciphertext is used for each business data to be uploaded In the form of storing business data in the blockchain, the business data stored in the blockchain includes: transaction hash, transaction type, block hash, Nonce string, etc. Therefore, the business directly read from the blockchain The data suffers from poor legibility. Contents of the invention [0003] The purpose of one or more embodiments of this specification is to provide a method for uplinking service data. The business data on-chain method includes: [0004] Obtaining service data to...
