BLOCKCHAIN-BASED VIRTUAL RESOURCE DELIVERY AND CROWDFUNDING METHOD AND DEVICE

摘要

This disclosure relates to blockchain-based virtual resource delivery and crowdfunding. In one aspect, a method includes receiving, by one or more blockchain nodes in a blockchain network and from a delivery node in the blockchain network, a target transaction constructed based on a category identifier and a resource amount specified by a delivery user. The category identifier is assigned to one of multiple crowdfunding project categories. The blockchain nodes(s) perform consensus verification on the target transaction. In response to determining that consensus verification is passed the blockchain node(s) establish a first correspondence between the category identifier and virtual resources corresponding to the resource amount. The blockchain node(s) store the first correspondence in a shared ledger of the blockchain network. The blockchain node(s) receive, from a crowdfunding node, project information of a crowdfunding project initiated by a crowdfunding user and establish a second correspondence between a category identifier and virtual resources.
