Application Of Block Chain Technology In The Field Of Cross-border Payments

In recent years,block chains have become a concept of rapid warming in the global Internet field,especially in the financial Internet industry,which has attracted more and more attention and exploration.Well-known financial institutions and scientific and technological enterprises around the world have announced their participation in block chain application development projects.Block chains extend from Bitcoin's particular scenario to more practical exploration and application.At present,the traditional cross-border payment method used in China has problems such as high cost,low efficiency and poor security.Block chain technology has unique advantages in the field of cross-border payment due to its openness,traceability,tamper-proof,and decentralization,and their effective interface will be conducive to simplifying the payment process,realizing real-time settlement,and improving information security.This will solve the many problems of cross-border payment,greatly reduce the costs and risks of cross-border payment,and improve the payment efficiency.At present,the research on the application of block chain technology in the field of cross-border payment is still in its initial stage.There are still many problems in the implementation of system design and software development that require in-depth research and practice.This paper mainly studies the application of block chain technology in cross-border payment,and explores the feasibility of applying block chain technology to cross-border payment through system design and simulation system implementation.This paper briefly introduces the characteristics and operating mechanism of the Ripple system based on block chain technology,and analyzes the defects of the traditional cross-border payment service represented by cheque exchange.The advantages of block chain technology to enhance security and efficiency in meeting cross-border payment business processes and functional realization are discussed.In this paper,the business requirement and function requirement of the cross-boundary payment system based on block chain,Guangdong and Hong Kong,are analyzed in detail.Based on this,the system design of simulated cross-border payment system based on Busby block chain is proposed,and the software architecture of the system is expounded.This paper designs and implements four functional modules of the simulation system,including registration module,login module,remittance module and query module.Finally,the simulated cross-border payment system based on block chain technology is tested,the test steps,data,expected results and actual results of each function are described,and the relevant interface is displayed to ensure the normal use of the functional modules of the system.At the same time,Also preset some special cases,test the processing effect of the system in special cases,find out possible problems,and further improve the system.
