Abstract: A blockchain-based data processing method, device, and a computer-readable storage medium are provided. A first resource acquisition request of an object identification is transmitted for a target virtual resource to a blockchain network to make the blockchain network query a target ticket identification associated with the object identification and the target virtual resource based on the first resource acquisition request. Metadata is acquired having a binding relationship with the target ticket identification. The target ticket identification is used for characterizing that the object identification has ownership of the target virtual resource. The target virtual resource is acquired according to the metadata returned by the blockchain network. The target virtual resource is controlled to perform an interaction output in response to a triggering operation for interacting with the target virtual resource.
