A blockchain cross-border cross-bank payment method and system based on baas architecture

Abstract

The invention discloses a block chain cross-border cross-bank payment method based on the Baas architecture, which includes the following steps: the bank imports the user's account information into the cloud server center group and uses block chain technology to save it, and the cloud server center group is set for the bank Settlement account; the user initiates a payment request to the bank to which the payment account belongs; the bank to which the payment account belongs sends the payment request to the cloud server center group, and each cloud server center in the cloud server center group judges whether the payment can occur through a consensus algorithm; if the payment can occur , each cloud server center will reduce the balance of the payment account and the bank settlement account to which the payment account belongs, and increase the balance of the collection account and the bank settlement account to which the collection account belongs. The amount of reduction or increase is equal to the payment amount. The invention also provides a corresponding payment system. This payment method does not use a third-party intermediary, but conducts transactions through the server center, so as to realize the reduction of cross-border and cross-bank payment costs and the improvement of service quality.

Description

technical field [0001] The present invention relates to the financial field, in particular to a blockchain cross-border cross-bank payment method and system based on Baas architecture. Background technique [0002] Today, e-commerce has gradually developed from localization to globalization, and global fund transfers have become more frequent with the process of globalization. In this case, cross-border cross-bank payment becomes more and more important, which can help users and merchants conduct transactions directly, facilitate shopping and consumption around the world, and compared with local shopping intermediaries, direct transactions can improve shopping Category, can also guarantee the quality of goods, convenient after-sales service. Therefore, how to realize convenient cross-border cross-bank payment has become an urgent problem to be solved. [0003] The currently adopted solution is through a third-party intermediary. Consider a scenario, A in China transfers 1...

AI Technical Summary

Problems solved by technology

First, third-party intermediaries need to have considerable qualifications and credit. Only in this way will banks cooperate with them, which leads to high entry barriers for corresponding services and relatively scarce service volume.

Second, due to the introduction of a third-party intermediary, the payment cost will inevitably rise, which has a great impact on the situation of small amounts

Third, the scalability is poor. Both the bank and the third party need to invest a lot of energy in the early stage to formulate the details of the service. As the number of participating banks increases, the maintenance cost of the third-party intermediary increases, and the pressure increases greatly.

Fourth, there is a delay in the transfer. In order to save costs, the third party generally packs small payments and settles them at a fixed time, which causes a delay in the arrival of the account. A cross-border payment business may consume several days

In e-commerce, this gives customers a poor experience

Fifth, due to the incompatibility of data, it is difficult to ensure the consistency of transaction data. A single transaction needs to be recorded at the paying bank, third-party intermediary, and receiving bank. Every once in a while, the bank sorts out all transactions When considering the frequent and wide range of transactions, the cost is high, and due to the incompatibility of data, once there is a problem with the transfer, it becomes very troublesome to track down the problem, which requires the participation of two banks and a third party. Problems are common for small transactions and can be costly for banks and third parties
