Cross-border payment method and device based on blockchain, and medium

Abstract

The invention discloses a cross-border payment method and device based on a block chain and a medium. The method comprises the steps of receiving a payment request initiated by a remittance party , wherein the payment request comprises remittance party information, and the remittance party information comprises a remittance party visa type; determining a priority level corresponding to the remittance party visa type according to the remittance party visa type and a preset corresponding relationship, and sorting all current to-be-executed payments according to the priority level; and accordingto the payment request, executing a payment action in an order corresponding to the payment order, and writing a payment result into a block chain platform. Typical characteristics of the block chaintechnology are integrated innovation of information technologies such as distributed data storage, point-to-point transmission, a trust consensus algorithm, an encryption algorithm and the like, and the block chain technology has the characteristics of generalization, trust consensus, information tamper resistance, openness and the like, and is suitable for being applied to payment services requiring high mutual trust of two transaction parties. The efficiency is improved, and a user can complete a cross-border payment service without waiting for too long time.

Description

Technical field [0001] This application relates to the field of payment, in particular to a blockchain-based cross-border payment method, device and medium. Background technique [0002] Cross-border payments involve multiple currencies, exchange rate issues, cumbersome processes, and long settlement cycles: traditional cross-border payments are basically non-real-time, and banks process transactions in batches at the end of the day. Usually, a transaction takes more than 24 hours to complete. The cross-border payments of some banks seem to be real-time, but in fact, the receiving bank makes a certain amount of advance payment based on the credit of the remittance bank, and then performs fund settlement and reconciliation at the end of the day. The business processing speed is slow and serious. It reduces the user experience and wastes the user's time. Summary of the invention [0003] In order to solve the above problems, this application proposes a blockchain-based cross-border...
