Description

Financial market fund settlement method based on block chain and node device

Technical Field

The application relates to the field of payment settlement, in particular to a financial market fund settlement method and a node device based on a block chain.

Background

The financial market bilateral business refers to a business that the two parties of the fund collector complete fund settlement through CIPS (Cross-border Payment System) and complete transfer of the relationship between the debt and the debt, such as cash transaction and recycle of the bond. In order to support different financial market transaction settlement services at home and abroad, the financial market bilateral service mode supported by the existing CIPS is as follows: after the financial market business enters Settlement, SSS (security Settlement Systems) sends financial market business Settlement messages to CIPS, the messages are added with business information, the CIPS finishes fund delivery of both parties of Settlement according to the messages and feeds back the results to the SSS, and the SSS finishes corresponding financial market business after receiving the receipt.

The inventor finds that the bilateral business mode in the prior art is a serial business processing and message transmission mode, and the next link can be processed only after the previous link is processed, so that the transaction processing time is increased, and the business processing efficiency is low; meanwhile, due to the security limitation of the cross-border network, the current CIPS only supports the access of the direct participants in the environment, and the overseas participants only rely on the special Financial text network of SWIFT (Society for world bank Financial Telecommunications association) and the direct participants in the environment to perform message transmission, so the overseas participants cannot directly participate in the bilateral service of the CIPS.
