The fixed field may be an Identification (ID) field of the producer, and the message data may be sorted in ascending order of the ID of the producer. The fixed fields may be predetermined by the message queue intelligent contract producer. The fixed field can be adjusted through intelligent contract upgrading, it needs to be stated that consensus needs to be achieved for intelligent contract upgrading, for example, if the fixed field needs to be adjusted, an intelligent contract voting proposal can be initiated, and whether upgrading is successful or not is determined according to the voting result of the block chain network. The message queue intelligence contract may also order message data according to the time of receipt of the uplink transaction request in the message.
