An online cross-border transfer payment method for users between commercial banks based on a block chain

Abstract

The invention discloses an online cross-border transfer payment method for users between commercial banks based on a block chain. A traditional cross-border transfer payment technology system betweencommercial banks and an emerging virtual digital encryption currency cross-border transfer payment technology system based on a block chain technology are fused. Certain national legal currencies areused as intermediary currencies. Medium currency is used as a carrier for value conversion between different countries of currency. Value conversion between different countries of currency is realizedby using the smart contract. Compared with the prior art, the method has the advantages that the virtual digital currency is replaced, point-to-point transmission of cross-border payment between commercial banks is realized by the aid of an alliance chain in a block chain technical system on the basis of existing financial supervision of cross-border payment of the commercial banks, and the technical scheme has the technical characteristics of controllability, anonymity and traceability so as to meet financial supervision requirements between the international and the regions.

Description

technical field [0001] The invention relates to the field of block chain payment, in particular to a block chain-based online cross-border transfer payment method for users among commercial banks.

Both have their own advantages and disadvantages, but on the whole it is difficult to meet the needs of convenient and safe user use and the government supervision needs of traceability and controllable anonymity

Specifically, the traditional cross-border transfer payment technology between commercial banks meets the current international and regional financial regulatory needs, but has poor timeliness, high costs, and complicated procedures. At the same time, the global bank that provides communication services for cross-border financial transfers The Society for Financial Telecommunications (SWIFT) has suffered multiple security attacks in recent years, its security has been questioned, and its rigid system architecture has also been criticized by the industry

The technology system based on blockchain technology to realize cross-border transfer payment with virtual digital encrypted currency has obvious advantages in terms of timeliness and security, but the virtual digital encrypted currency it uses faces different degrees of policies in various countries around the world. Risk, the unstable value of the publicly issued virtual digital currency has caused huge changes in the value of cross-border transfer payments, and its operation also has a high technical threshold, making it difficult for ordinary users to access

At the same time, the high anonymity of the technical system also brings great challenges to financial supervision
