Description

A cross-border transaction settlement and payment method based on blockchain Technical Field

[0001] The present invention relates to the field of cross-border transaction technology, and specifically to a cross-border transaction settlement and payment method based on blockchain. Background Art

[0002] As people's living standards gradually improve, the number of people traveling abroad for tourism, work, and study continues to rise annually. This has led to a continued surge in demand for remittances and a growing global demand for cross-border payment services. Cross-border payments are typically conducted through cross-border settlement between commercial banks. Commercial banks operate in two modes: the agency model and the clearing model. The agency model primarily involves a Chinese bank entrusting a foreign bank to act as its overseas agent, with overseas enterprises opening RMB accounts at the Chinese bank's agent bank. The clearing model, on the other hand, primarily involves transactions between a Chinese bank's domestic head office and its overseas branches, with overseas enterprises opening RMB accounts at the Chinese bank's overseas branches. Technical issues

[0003] Currently, cross-border transfer payments between commercial banks have poor timeliness, high costs, and complicated procedures. At the same time, SWIFT, which provides communication services for cross-border financial transfers, has suffered security attacks many times in recent years, and its security has been questioned. This requires a safe and convenient payment method. To address the above problems, the inventors proposed a blockchain-based cross-border transaction settlement and payment method to solve the above problems. Technical Solutions

[0004] In order to solve the problems of poor timeliness and high costs of cross-border transfer payments between commercial banks, the purpose of the present invention is to provide a cross-border transaction settlement and payment method based on blockchain.

[0058] Working principle: First, the user initiates a cross-border trade transaction request. The transaction terminal 1 receives the cross-border trade transaction request. The user information encryption module 11 encrypts the transaction information and user information and sends it to the information transceiver module 12. The information transceiver module 12 sends the data to the payment network connection module 2. The payment network connection module 2 sends the data to the bank server module 31. The bank server module 31 sends the data to the data comparison module 32. The data comparison module 32 retrieves the data in the database module 34 and compares it with the received data to confirm the authenticity of the source of the payment request and determine whether the payment can be made. If the data comparison results are consistent, the judgment result of whether the payment can be made is yes. The data comparison module 32 sends the judgment result to the sending module 33. The sending module 33 sends a payment request to the transaction module 4, the processing module 41 processes the received data for further comparison, and the processing module 41 then sends a payment permission instruction to the paying bank module 42. The paying bank module 42 settles the payment to the receiving bank module 43. The receiving bank module 43 receives the payment and sends the payment result to the transmission module 44. The transmission module 44 transmits the transaction result to the blockchain module 5 for storage. At the same time, the transmission module 44 sends the transaction result to the information transceiver module 12. The information transceiver module 12 sends the received information to the transaction display module 13, and the transaction display module 13 displays the payment result. In this way, the timeliness and complicated procedures in cross-border trade transaction payments can be reduced, thereby achieving the purpose of improving transaction payment efficiency;

[0059] When the transaction terminal 1 is in use, the movable rod 72 is first moved. The movable rod 72 drives the transaction terminal 1 to move through the disassembly assembly 6. At the same time, the movable rod 72 drives the rack 77 to move. The rack 77 drives the gear 75 to rotate along the shaft 74, and the gear 75 is positioned by the elastic paddle 78 to prevent the movable rod 72 from sliding down due to gravity. In this way, the height of the transaction terminal 1 can be adjusted, thereby facilitating the operation of the transaction terminal 1. When the transaction terminal 1 needs to be moved for use, the limit plate 69 is moved in the opposite direction, and the limit plate 69 drives the connecting rod 77 to move. The connecting rod 67 moves, and at the same time, the limit plate 69 compresses the spring 610, causing the spring 610 to generate elastic force. The connecting rod 67 drives the push plate 68 to move in the limit groove 66, and the push plate 68 pushes the limit block 65 out of the limit groove 66. At the same time, the limit block 65 drives the elastic plate 64 to undergo elastic deformation, and then the elastic force of the spring 610 drives the push plate 68 to reset. Then the transaction terminal 1 is moved, and the transaction terminal 1 drives the mounting block 62 to move out of the T-slot 63. In this way, the transaction terminal 1 can be easily disassembled, thereby facilitating mobile use.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
