Blockchain-based trade document management system and management method

Abstract

The invention discloses a blockchain-based trade document management system and a blockchain-based trade document management method. The blockchain-based trade document management system comprises a trade blockchain, and a trade platform, a demander node, a financing node, a supervision node and a block verification unit which are connected with the trade blockchain through a network, wherein thetrade blockchain is used for storing original trade information and trade process documents related to financing and supervision in the form of blocks; the trade platform, the demander node, the financing node and the supervision node insert block data of the original trade information and the trade process documents into the trade blockchain; and the block verification unit is used for performinginformation tampering and information integrity verification on the block data. Thus, the technical purposes of applying the blockchain technology in the trade circulation field so that information of independent institutions such as demander and supplier, financing, taxation and supervision is shared safely, storing the trade process documents generated in the approval and audit processes and the original trade information separately, and performing tampering verification and integrity checking can be achieved.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a blockchain-based trade document management system and management method. Background technique [0002] The current online trade has the characteristics of scattered information, easy to tamper, low reliability and vulnerability to network attacks. In particular, the trust system of all trading parties is not unified, which has caused the problems of opaque trade information and high investment risks. [0003] For example, the patent application number is CN106878396 "Trade Information Processing Method, Device and System", by storing all information related to supply nodes, demand nodes, platform nodes and supervision nodes in the form of blockchain, and using a unified network consensus mechanism The purpose of information authentication is to improve the reliability, tamper-proof and security of trade information, and improve the trade experience of...

AI Technical Summary

Problems solved by technology

However, the present invention connects many related party nodes to a block chain, and sends redundant and unnecessary information to irrelevant nodes when broadcasting information, for example, sends unnecessary taxation and financing information to inspection, Quarantine, transportation and other independent agencies, thus causing certain information leakage and security risks;

Therefore, although the current blockchain-based trade information processing technology solves the security, reliability and tamper-proof of information, there are problems such as information abuse and inapplicability of the review and approval process.
