step 401: receiving first notification information sent by a queue service program;

step 402: the data synchronization node in the block chain network judges whether the data synchronization is finished, if so, step 403 is executed, otherwise, step 404 is executed;

step 403: the data synchronization node analyzes the theme message carried by the first notification information;

step 404: the data synchronization process in the blockchain network continues to be monitored.

Step 405: and according to the analyzed theme message, carrying out serialization processing on the data stored in the data synchronization node to form target data to be pushed.

Step 406: and the data synchronization node responds to the first notification information and pushes target data to the queue service program.

In one embodiment of the invention, the method further comprises:

encrypting the data in the block according to the type of the data in the block;

decrypting the received data corresponding to the hash value to form plaintext data usable by the blockchain network and/or the respective application. In an embodiment of the present invention, the acquired data to be stored may be ciphertext data subjected to asymmetric encryption processing, or plaintext data subjected to encryption processing, where whether the data to be stored is encrypted or not needs to be processed according to an instruction of a data attribution user.

Specifically, when the application program has a function of processing ticket service data, the topic message subscribed by the application program is a ticket; the data synchronization node carries out serialization processing and rewriting on the updated data according to the theme message to form bill data to be pushed, so that the defect that the application program can only form usable bill data through secondary processing on the acquired data is overcome; furthermore, the data synchronization node can also perform iterative processing on the stored data according to the analyzed first notification message, and periodically send the data to the service queue program, so that the defect that the application program frequently requests the data synchronization node for the data is avoided.

Fig. 8 is an optional flowchart of a data processing method according to an embodiment of the present invention, where the method shown in fig. 8 is applied to a blockchain service system, and the optional flowchart of the data processing method includes the following steps:

step 801: and the blockchain network receives third notification information sent by the application program through the queue service program.

Wherein the third notification information carries a topic message subscribed by the application program;

step 802: and when the data synchronization node in the block chain network completes data synchronization, the data synchronization node responds to the third notification information and pushes target data to the application program.

Therefore, the target data can be matched with the theme message carried by the third notification information.

the data synchronization node determines the priority of different theme messages in the third notification information according to the analyzed theme messages; the data synchronization node determines the processing sequence of different target data based on the determined priorities of different subject messages; and the data synchronization node sequentially carries out serialization processing on the data stored by the data synchronization node based on the processing sequence of the different target data to form target data pushed to different subject messages of the queue service program. Since the number of the application programs subscribing the topic message to the queue service program may be large, according to the technical scheme shown in this embodiment, the processing order of different target data is determined by determining the priorities of different topic messages, and the target data required by the topic message with higher priority can be preferentially processed, so as to reduce the waiting time for the application program corresponding to the topic message with higher priority to acquire the target data. Specifically, the priorities of different topic messages in the third notification information may be characterized by the priority identifiers of the topic messages, and optionally, the topic message subscribed by the application program, where the application program pays a fee to the blockchain network and/or the queue service program operator, has a higher priority than the topic message subscribed by the application program that obtains the target data for free.

and the data synchronization node rewrites the data stored by the data synchronization node according to the analyzed theme message to form target data matched with the application program. In the existing technical solution, because the data acquired by the application from all nodes of the blockchain network is in a fixed format, the application often needs to request target data from all nodes of the blockchain network many times in order to complete the application, which easily causes data redundancy, and wastes the data processing capability of all nodes of the blockchain network, according to the analyzed topic message, the data stored in the data synchronization node is rewritten, and the application acquires the target data corresponding to the subscribed topic message, which avoids the secondary processing of the application on the acquired data, saves the processing event of the application on the data, improves the data processing efficiency, and meanwhile, the pushed target data has stronger adaptability. Specifically, when the application program has a function of processing ticket service data, the topic message subscribed by the application program is a ticket; the data synchronization node carries out serialization processing and rewriting on the updated data according to the theme message to form bill data to be pushed, so that the defect that the application program can only form usable bill data through secondary processing on the acquired data is overcome; furthermore, the data synchronization node can also perform iterative processing on the stored data according to the analyzed first notification message, and periodically send the data to the service queue program, so that the defect that the application program frequently requests the data synchronization node for the data is avoided.

In one embodiment of the present invention, the data synchronization node is capable of checking the acquired blocks generated by the neighboring nodes in the blockchain network; when the data passes the verification, storing the acquired data in the block in a distributed storage system corresponding to the data synchronization node; and receiving a hash value sent by the distributed network, wherein the hash value is used for representing the storage position of the data to be stored in the distributed network. Optionally, the data synchronization node is a full node in a corresponding block chain network. According to the technical scheme shown in the embodiment, when the used distributed network is an InterPlanetary File storage System (InterPlanetary File System), if the data to be stored exceeds a specification threshold value of 256K, the data to be stored is divided to form a plurality of data blocks; storing the plurality of data blocks in a plurality of nodes of the distributed network; the number of the nodes is equal to the number of the data blocks, and due to the uniqueness of the hash value, when the data to be stored in any one node changes, the corresponding hash value also changes, so that the data to be stored is prevented from being maliciously modified.

and a blockchain network module 902, configured to, in response to the third notification information, push target data to the application program, so as to implement matching between the target data and a theme message carried by the third notification information. Therefore, the target data can be matched with the theme message carried by the third notification information. Wherein the queue service program module 901 is assumed by the corresponding interface of the blockchain network module 902.

step 1001: the fourth notification information is sent to the queue service program by the application program;

therefore, the application program can subscribe the corresponding topic message to the queue service program.

Step 1002: the queue service program analyzes the fourth notification information and generates fifth notification information carrying subject information;

step 1003: the queue service program sends the fifth notification message to a data synchronization node of the blockchain network;

step 1004: and the data synchronization node receives fifth notification information sent by the queue service program.

Step 1005: and the data synchronization node responds to the fifth notification message and pushes target data to the queue service program.

Step 1006: and the queue service program receives the target data pushed by the data synchronization node.

Step 1007: the queue service program pushes the received target data to the application program.

Step 1008: and after receiving the target data pushed by the queue service program, the application program updates and analyzes the data in real time according to the self requirement.

In the existing technical solution, because the data acquired by the application from all nodes of the blockchain network is in a fixed format, the application often needs to request target data from all nodes of the blockchain network many times in order to complete the application, which easily causes data redundancy, and wastes the data processing capability of all nodes of the blockchain network, according to the analyzed topic message, the data stored in the data synchronization node is rewritten, and the application acquires the target data corresponding to the subscribed topic message, which avoids the secondary processing of the application on the acquired data, saves the processing event of the application on the data, improves the data processing efficiency, and meanwhile, the pushed target data has stronger adaptability.
