Blockchain-based resource transfer-out processing method, device and system

Abstract

The embodiment of the present specification provides a resource transfer-out processing method, device and system based on a blockchain, wherein a resource transfer-out processing method based on a blockchain comprises: querying a total amount of resources of a resource flow platform through a first blockchain node according to a resource transfer-out request of a transfer-out mechanism; the resource transfer-out request carries a transfer-out amount. If the total amount of resources is less than the transfer-out amount, a resource allocation request containing the transfer-out amount is generated and sent to a second blockchain node for resource allocation processing. After successful resource allocation processing, a resource allocation voucher of the transfer-out mechanism corresponding to the allocation account of the second blockchain node is generated. Based on the generation of the resource allocation voucher, a proxy transfer-out request is sent to the first blockchain node for proxy processing of resource transfer-out.
