According to the Securities Times, at present, all cross-border payment service entities have not solved the problem of centralized control and slow payment processing. Therefore, the use of blockchain technology to innovate digital currency has become a key force for technology and financial enterprises to attack. In addition to the global network social giant Facebook released the digital currency Libra and the creation of the Calibra digital wallet and publicly stated the purpose of fast and convenient cross-border payment, Visa, the world's largest credit card company, also launched Visa B2B Connect. Business-to-business cross-border payment market, while Visa's direct competitor, the world's second largest credit card issuer, MasterCard also created its digital currency BitCardTour. It is envisaged that these digital currencies can be directly exchanged with fiat money and use peer-to-peer transactions to increase the timeliness of cross-border payments and further reduce payment costs. According to McKinsey estimates, the introduction of blockchain technology and digital currency can save about $4 billion in cross-border payments each year.
