Blockchain-based data processing method and device and readable storage medium

A blockchain-based data processing method performed by a computer device, comprising:

• a terminal device displaying a target virtual resource in a digital asset application logged in through an object identification according to resource data for the target virtual resource, wherein the displaying the target virtual resource according to the resource data comprises rendering the resource data by:
• acquiring a three-dimensional vertex coordinate of a vertex of the target virtual resource in a three-dimensional space in the resource data to be rendered;
• acquiring a target projection position;
• calling a vertex shader;
• mapping the three-dimensional vertex coordinate to a two-dimensional space according to the target projection position to obtain a two-dimensional vertex coordinate of the vertex of the target virtual resource under the target projection position;
• drawing a two-dimensional line corresponding to the two-dimensional vertex coordinate and a two-dimensional plane generated by the two-dimensional line in the two-dimensional space according to a connection relationship between vertices of the target virtual resource;
• and
• displaying the target virtual resource under the target projection position in the presentation interface according to the two-dimensional line and the two-dimensional plane,
• wherein
• the target virtual resource is obtained according to metadata returned by a blockchain network,
• the metadata is acquired by the terminal device transmitting a first resource acquisition request for the target virtual resource to the blockchain network through the object identification,
• the first resource acquisition request is used for:
• indicating the blockchain network,
• querying a target ticket identification associated with the object identification and the target virtual resource, and
• acquiring the metadata having a binding relationship with the target ticket identification;
• and
• the target ticket identification is used for characterizing that the object identification has ownership of the target virtual resource;
• and
• controlling the target virtual resource to perform an interaction output in response to a triggering operation for interacting with the target virtual resource.

• a memory storing a plurality of instructions;
• and
• a processor configured to execute the plurality of instructions, wherein upon execution of the plurality of instructions, the processor is configured to:
• transmit a first resource acquisition request of an object identification 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, wherein in order to transmit the first resource acquisition request, the processor is configured to:
• acquire a ticket identification to be verified for the target virtual resource in response to a resource acquisition instruction in a digital asset application logged in through the object identification;
• generate the first resource acquisition request according to the ticket identification to be verified and the object identification, and signing the first resource acquisition request to obtain signature information;
• and
• transmit the first resource acquisition request carrying the signature information to the blockchain network, wherein
• the signature information is used for indicating validity of the blockchain network verifying the object identification;
• the object identification is used for indicating the blockchain network to acquire a ticket identification set having a binding relationship with the object identification in a case that determining the object identification having a legal permission, wherein
• the ticket identification set comprises the target ticket identification;
• the ticket identification to be verified is used for indicating the blockchain network to determine a holding permission of the object identification for the target virtual resource according to the ticket identification set;
• and
• the holding permission is used for characterizing that the ticket identification to be verified is the same as the target ticket identification;
• acquire metadata 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;
• acquire the target virtual resource according to the metadata returned by the blockchain network;
• and
• control the target virtual resource to perform an interaction output in response to a triggering operation for interacting with the target virtual resource.
