Blockchain-based data processing method and device

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations, comprising:

• receiving, by a node in a blockchain network, service data generated by a first service, wherein the service data comprises a data structure having a field a value of which indicates that the first service is associated with a first processing level;
• storing, by the node based on the value of the field, the service data in a first data processing queue selected from a plurality of data processing queues, wherein the first data processing queue corresponds to the first processing level, and each of the plurality of data processing queues corresponds to a different processing level;
• and
• generating, by the node, a new block that stores the service data read from the first data processing queue, and additional service data read from one or more of the plurality of data processing queues,
• wherein a quantity of service data read from each of the one or more of the plurality of data processing queues is determined in accordance with a condition for prioritizing storage of content from the plurality of data processing queues in the new block.

A system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
• receiving, by a node in a blockchain network, service data generated by a first service, wherein the service data comprises a data structure having a field a value of which indicates that the first service is associated with a first processing level;
• storing, by the node based on the value of the field, the service data in a first data processing queue selected from a plurality of data processing queues, wherein the first data processing queue corresponds to the first processing level, and each of the plurality of data processing queues corresponds to a different processing level;
• and
• generating, by the node, a new block that stores the service data read from the first data processing queue, and additional service data read from one or more of the plurality of data processing queues,
• wherein a quantity of service data read from each of the one or more of the plurality of data processing queues is determined in accordance with a condition for prioritizing storage of content from the plurality of data processing queues in the new block.
