Cross-border payment based on block chain technology connects all nodes involved in payment settlement, including importers and exporters, through block chain technology, to jointly maintain payment transaction information and participate in consistency verification. If the importer fails to receive the true and valid exporter’s delivery information after payment through the blockchain, the importer will deny the payment information during the consistency verification process, and the exporter will not receive the remittance. Therefore, through blockchain payment, all parties involved in transactions jointly maintain transaction records and jointly participate in verifying transaction information, which greatly reduces payment risks in international trade. 2. Improve the efficiency of cross-border payment By adopting the solution of blockchain payment. Since all participating nodes in the blockchain network jointly maintain the verification information, ensuring the consistency of information, there is no need for complex information synchronization and reconciliation in blockchain payment, greatly improving the efficiency of cross-border payment. 3. Saving bank business resources In the blockchain payment system, different banks can be realized based on the alliance chain, so that the exchange payment between different currencies can get rid of the participation of intermediate associated banks and directly carry out real-time payment; In a blockchain-based payment platform, each bank needs only one reserve account, saving the standby capital that would otherwise be stored in an intermediary and increasing the resources that can be allocated to its own banking operations. The solution becomes even more attractive when a large number of banks participate in the network. Therefore, cross-border payment based on blockchain technology can greatly save the resources of banks. To sum up, with the decentralized technology adopted by blockchain payment, the transaction parties no longer need to rely on a central institution to be responsible for fund settlement, but directly transfer value based on a consensus mechanism algorithm that does not need trust and coordination. Therefore, blockchain payment provides a better solution for cross-border payments than traditional wire transfers.
