Abstract

A node in a blockchain network receives service data generated in a specified time period, where the service data comprises label information used to represent a processing priority of the service data. The node determines, when a new block is generated, a throughput that corresponds to the label information based on a predetermined mapping relationship between label information and a throughput. The node obtains service data that satisfies the throughput and that comprises the label information from a data processing set based on the throughput, where the service data is stored in the data processing set. The service data is stored in the new block.
