The data persistent storage method is applied to the user terminal 10, and the method is executed by application software installed in the user terminal 10. The blockchain network 20 establishes a network connection with the user terminal 10 to realize the transmission of data information. The user terminal 10 is a terminal device used to implement a data persistent storage method to achieve persistent storage of Channel objects, such as a desktop computer, a notebook computer, a tablet computer, or a mobile phone, etc. The blockchain network 30 is a number of devices in the Internet. The terminal equipment and management server are based on a terminal network composed of smart contracts. FIG. 2 only shows one user terminal 10 and the blockchain network 20 for information transmission. In practical applications, the blockchain network 20 can also perform information transmission with multiple user terminals 10 at the same time.

As shown in Fig. 1, the method includes steps S110 to S160.

S110: If a channel creation request input by the user is received, create a storage channel containing a Channel object in a random storage medium of the SDK node corresponding to the user terminal according to the channel creation request.

If a channel creation request input by the user is received, a storage channel containing a Channel object is created in the random storage medium of the SDK node corresponding to the user terminal according to the channel creation request. The blockchain network contains multiple user terminals and a management server that manages the user terminals. The management server is the sorting service node in the blockchain network. A user terminal corresponds to an SDK node, and the SDK node is the user terminal. In the Software Development Kit (Software Development Kit), one SDK node can correspond to one or more Peer nodes in the blockchain network, and a storage channel can contain multiple Peer nodes, and each Peer node is associated with a user terminal. The SDK nodes in each storage channel are connected, and the data stored in each storage channel are isolated from each other; the ordering service node can receive transactions that include endorsement signatures, order the transactions or package them to generate blocks, and broadcast the information to the peer node. The ordering service node can Ensure that nodes in the same storage channel receive the same messages and have the same logical sequence; SDK nodes can provide services to users, and one or more Channel objects can be created in one SDK node, and one Channel object in the SDK node is Corresponding to a Peer node included in the SDK node, that is, an SDK node can correspond to one or more Peer nodes, each Channel object belongs to a storage channel in the blockchain network, and a storage channel belongs to All Channel objects are the same, and the Channel object is the data that needs to be persistently stored. Persistent storage of the data corresponding to the Channel object can maintain the high availability of the Channel object. You can use multiple Channel objects in a storage channel. Realize distributed storage of information. The user can input a channel creation request in the user terminal and create a new storage channel through the user terminal. Specifically, the channel creation request includes channel name, ordering service node information, peer node information, data signature information, etc., ordering service node information That is the node information of the ordering service node, the Peer node information is the Peer node contained in the storage channel, and the data signature information is the information used to sign the data in the storage channel. The specific information contained in the channel creation request is passed. Information can create a storage channel that contains a Channel object.

The user terminal includes a random storage medium corresponding to the SDK node. The random storage medium is the medium used to temporarily store data information, such as the memory in the user terminal. The SDK node includes a The recorded data table and one or more Channel objects. If an SDK node contains a Channel object, the data table of the SDK node contains only one channel record information corresponding to the Channel object; if a SDK node contains a Channel object If multiple Channel objects are included, the data table of the SDK node contains multiple channel record information corresponding to the multiple objects. The corresponding Channel object can be created according to the channel creation request. The created Channel object is stored in the random storage medium of the SDK node; specifically, the Channel object stores the information for creating the storage channel, including the channel name and ordering service node information , Peer node information, data signature information, etc.

In an embodiment, as shown in FIG. 3, step S110a is further included after step S110.

S110a: Send the Channel object to the ordering service node corresponding to the ordering service node information according to the ordering service node information in the Channel object, so as to initialize the Channel object.

According to the ordering service node information in the Channel object, the Channel object is sent to the ordering service node corresponding to the ordering service node information to initialize the Channel object. After the storage channel is created, the specific information of the created storage channel and the Channel object are only stored in the SDK node that generated the storage channel. In order for the newly created Channel object to realize the function of distributed storage of information, the newly created Channel object needs to be The Channel object is initialized. Specifically, the Channel object is sent to the ordering service node corresponding to the ordering service node information in the Channel object. After receiving the Channel object, the ordering service node can send the Channel object to the Peer node information in the Channel object. The Channel object is sent to the SDK node corresponding to the Peer node information. The Peer node information contains one or more Peer nodes. Each Peer node is associated with an SDK node in a user terminal. The storage channel composed of the same Channel object stores and interacts with information, that is, realizes distributed storage of information.

S120: Serialize the Channel object and store it persistently in the SDK node corresponding to the user terminal.

After serializing the Channel object, it is persistently stored in the SDK node corresponding to the user terminal. Specifically, the SDK node contains the corresponding NAS network disk and database. The NAS network disk is used to persistently store the Channel file corresponding to the Channel object, and the database is used to record information about the new channel corresponding to the storage channel to which the Channel object belongs. For persistent storage.

In an embodiment, as shown in FIG. 4, step S120 includes sub-steps S121, S122, S123, and S124.

S121. Serialize the Channel object to obtain a Channel file.

Serialize the Channel object to obtain the Channel file. Because the Channel object is a programming language, in order to persist the information contained in the Channel object, the Channel object needs to be serialized into a Channel file, which is a binary file, so the Channel file can be stored conveniently and persistently. When opening the binary file, users can only see one line of garbled code, so the Channel file can be deserialized to generate the corresponding Channel object before it can be used normally.

S122. Store the Channel file in the NAS network disk corresponding to the SDK node and obtain storage path information.

The Channel file is stored in the NAS network disk corresponding to the SDK node and the storage path information is recorded. The NAS network disk is a readable and writable storage medium corresponding to the SDK node. For example, each SDK node corresponds to a shared NAS network disk. The NAS network disk can store data persistently, and the obtained channel file can be stored. Store it in the corresponding NAS network disk and obtain the corresponding storage path information. The storage path information includes the file name and storage address of the Channel file.

For example, the storage path information corresponding to a Channel file is shown in Table 1.

文件名file name	存储地址Storage address
org1-mychannelorg1-mychannel	/network_resources/org1-mychannel.channel/network_resources/org1-mychannel.channel

Table 1

S123: Generate new channel record information according to the channel creation request and storage path information.

According to the channel creation request and the storage path information, new channel record information is generated. Specifically, the specific information in the channel creation request and the storage path information are obtained, and the corresponding new channel record information is generated. The new channel record information is the summary information of the created storage channel. In the newly added channel record information Including channel name, ordering service node information, peer node information, file name and storage address of the Channel file and other information.

S124. Store the newly added channel record information in the database of the SDK node.

Store the newly added channel record information in the database of the SDK node. Store the new channel record information in the database corresponding to the SDK node to complete the creation of the storage channel. After storing the new channel record information, you can use the new channel record information stored in the database to compare the corresponding storage channel Information is retrieved to facilitate the use of users. The database may be a lightweight SQlite database. Compared with traditional databases such as MySQL or SQL Server, the lightweight database of SQlite stores data more concisely and efficiently. In addition, the Channel object cached in the random storage medium can also be stored in the database. If the random storage medium power failure information is lost, the Channel object corresponding to a certain storage channel can be obtained from the database and cached in the random storage medium. Obtain and use the Channel object quickly and easily.

S130. If a channel object acquisition request input by a user is received, acquire a Channel object corresponding to the channel object acquisition request in the user terminal as a target Channel object.

If the channel object acquisition request input by the user is received, the Channel object stored in the user terminal is acquired according to the channel object acquisition request. The user obtains and uses the corresponding Channel object to realize distributed storage of information. The user can obtain the corresponding Channel object by inputting the channel object acquisition request. The channel object acquisition request may include the Channel object name or the channel name.

In an embodiment, as shown in FIG. 5, step S130 includes sub-steps S131, S132, S133, S134, and S135.

S131: Determine whether there is a Channel object corresponding to the channel object acquisition request in the random storage medium of the SDK node corresponding to the user terminal to obtain a storage determination result.

It is judged whether there is a Channel object corresponding to the channel object acquisition request in the random storage medium of the SDK node corresponding to the user terminal to obtain the storage judgment result. The Channel object is created in the random storage medium of the SDK node. If the user terminal restarts and causes the Channel object stored in the random storage medium to be lost, before obtaining the corresponding Channel object, you can check whether the SDK node's random storage medium exists or not. The Channel object corresponding to the channel object acquisition request is judged. Specifically, the Channel object includes the channel name to which it belongs, and the data in the random storage medium can be queried through the Channel object name or channel name contained in the channel object acquisition request. If the data of the random storage medium queried contains the Channel object corresponding to the channel object acquisition request, the storage judgment result is that it exists; if the Channel object corresponding to the channel object acquisition request is not queried, the judgment result is that it does not exist.

S132: If the storage judgment result is yes, acquire the Channel object corresponding to the channel object acquisition request in the random storage medium as the target Channel object.

If the storage judgment result is yes, it indicates that the random storage medium of the current SDK node contains the Channel object corresponding to the channel object acquisition request, and the Channel object can be directly acquired as the target Channel object.

S133: If the storage judgment result is no, search the database of the SDK node according to the channel object acquisition request to acquire target channel record information corresponding to the channel object acquisition request in the database.

If the storage judgment result is no, the database of the SDK node is retrieved according to the channel object acquisition request to acquire the channel record information corresponding to the channel object acquisition request in the database as target channel record information. If the random storage medium does not contain the Channel object corresponding to the channel object acquisition request, the SDK node database can be retrieved according to the channel object acquisition request. The database records the channel record of each storage channel created based on the SDK node Information. The channel record information includes channel name, ordering service node information, peer node information, file name and storage address of the Channel file, and so on. Therefore, the channel record information in the database can be retrieved according to the channel object acquisition request to obtain and The channel object obtains a piece of channel record information corresponding to the request as the target channel record information. If the channel record information corresponding to the channel object acquisition request is not retrieved in the database, the corresponding storage channel is created according to the channel object acquisition request.

S134: Obtain, according to the target channel record information, the Channel file stored in the NAS network disk corresponding to the SDK node as the target Channel file as the target Channel file.

Acquire the Channel file stored in the NAS network disk corresponding to the SDK node as the target Channel file according to the target channel record information as the target Channel file. The channel record information includes the storage address corresponding to the channel, and each storage address points to a Channel file in the corresponding NAS network disk, and the Channel file stored in the corresponding NAS network disk can be obtained according to the storage address as the target Channel file .

S135. Deserialize the target Channel file according to a preset deserialization rule to obtain a target Channel object.

The target Channel file is deserialized according to the preset deserialization rule to obtain the target Channel object. Each Channel file is a binary file. When the Channel file is opened directly, the user can only see one line of garbled characters. Therefore, the target Channel file needs to be deserialized through the preset deserialization rules to obtain the corresponding target Channel object. The deserialization rule is used to deserialize the Channel file to obtain the rule information of the corresponding Channel object. Specifically, the deserialization rule contains the project name corresponding to the Channel object, and the Channel file is deserialized according to the project name You can get the Channel object. The project name includes the channel name, ordering service node information, peer node information, data signature information, etc.

In an embodiment, as shown in FIG. 6, step S130 further includes sub-step S136.

S136. Store the target Channel object in a random storage medium of the SDK node, so as to cache the target Channel object.

After obtaining the target Channel object, the target Channel object that is not stored in the random storage medium can be stored in the random storage medium of the SDK node, that is, the target Channel object is cached and cached to the target Channel object in the random storage medium It is convenient for users to use.

S140: Judge whether the target Channel object has been initialized to obtain an initialization judgment result.

It is judged whether the target Channel object has been initialized to obtain the initial judgment result. Before feeding back the target Channel object to the user, it is necessary to judge whether the target Channel object has been initialized. In some cases (the user terminal disconnects from the network) although the storage channel containing the Channel object is already in the local SDK of the user terminal Created in the node, but because the Channel object has not been initialized, the ordering service node and other peer nodes corresponding to the storage channel in the blockchain network have not obtained the information of the storage channel, that is, the information cannot be carried out through the storage channel Storage and interaction. Specifically, the user terminal corresponding to the SDK node of the target Channel object sends the object verification information of the target Channel object to the ordering service node (management server) included in the ordering service node information in the target Channel object, and the object verification information includes the target Channel object. The channel name of the channel to which the target Channel object belongs, the creation time of the channel to which the target Channel object belongs, the ordering service node feeds back the corresponding verification result according to the object verification information, and the verification result includes whether the ordering service node has stored information corresponding to the target Channel object, and obtain the verification As a result, it can be judged whether the target Channel object has been initialized. If the information corresponding to the target Channel object has been stored in the ordering service node, the result of the initialization judgment is Yes; if the information corresponding to the target Channel object is not stored in the ordering service node , The initial judgment result is no.

S150: If the initial judgment result is yes, feed back the target Channel object to the user.

If the initial judgment result is yes, the target Channel object is fed back to the user. If the target Channel object has been initialized, that is, the Channel object is available for use, the target Channel object is fed back to the user for use.

S160: If the initialization judgment result is no, initialize the target Channel object and feed it back to the user.

If the initialization judgment result is no, the target Channel object is initialized and then fed back to the user. If the target Channel object has not been initialized, in order to ensure that the target Channel object obtained by the user can be used, the target object needs to be initialized and then fed back to the user for use, and the target Channel object is sent to the target Channel object. The ordering service node corresponding to the ordering service node information can initialize the target Channel object. The specific initialization process is the same as the above steps. After the user receives the target Channel object that has been initialized, the storage channel corresponding to the target Channel object can be used To store and interact with information is to realize distributed storage of information.
