Method and device for checking and checking RMB cross-border payment based on blockchain architecture

Abstract

The present invention provides a method and device for querying and retrieving RMB cross-border payment based on a block chain architecture, wherein the method includes: receiving a query request at a query participant node, constructing a query request transaction, and adding the query request transaction to the block chain ;CIPS node registers the query request; the query participant node organizes the corresponding query message according to the query request transaction, constructs a query message transaction, and adds the query message transaction to the blockchain; CIPS node registers the query message ; The query participant node outputs the query reply message to the initiator of the query request according to the query reply message transaction. The above-mentioned technical solution improves the accuracy and efficiency of RMB cross-border payment inquiry and reply, ensures the reliability and security of cross-border payment inquiry and reply, and promotes the development of cross-border payment inquiry and reply business.

Description

technical field [0001] The present invention relates to the field of cross-border payment inquiry, check and review, and in particular to a method and device for cross-border payment inquiry and review of RMB based on a block chain architecture. Background technique [0002] The Cross-border Interbank Payment System (CIPS) provides fund clearing and settlement services for domestic and foreign financial institutions' cross-border and offshore RMB business, and is an important financial infrastructure in my country. [0003] The overall CIPS architecture involves CIPS stakeholders and peripheral systems. CIPS stakeholders include direct participants, indirect participants, initiators, and recipients. CIPS provides services to its direct participants, and indirect participants obtain services through direct participants. Originators and recipients can obtain services through direct participants or indirect participants. Direct participants need to be in China, and indirect ...

AI Technical Summary

Problems solved by technology

[0017] 1. The serial processing of each participating link is low in efficiency: from the inquiry service initiator initiating the business to receiving the inquiry reply information from the inquiry reply party, the intermediate message transmission has to pass through multiple parties and is transmitted serially. Errors in any link may lead to The service fails, and the service initiator needs to re-initiate the service request

And the serial processing of message delivery will also increase the probability of message loss, which will lead to lower efficiency of business processing

[0018] 2. The risk that business messages may be tampered with: in extreme cases, because messages are processed serially, the intermediate link may be able to tamper with business messages

The query and reply information needs to be stored independently by each party, and it may be lost if it is not stored properly

In addition, CIPS in the original system cannot guarantee whether the receiver of the forwarded query and reply message is correctly received and stored

[0019] For the above problems, no effective solutions have been proposed so far
