[0040] In order to make those of ordinary skill in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating the examples of the present application.

[0041] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples consistent with certain aspects of the present application as detailed in the appended claims.

[0042] As described in the background technology section, there is a problem in the prior art that data is stored in the blockchain, resulting in an excessive burden on the blockchain. In order to solve the above problem, the embodiments of the present application provide an information processing method, device, electronic device, medium and program product. By detecting whether each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client, if it is determined that the target blockchain fork node stores an expired information notification task, the expired information notification task is backed up and the expired information notification task in the target blockchain fork node is deleted, thereby maintaining the lightweight of the blockchain and reducing the burden on the blockchain.

[0043] Before introducing the information processing method provided by the present application, the information processing system for implementing the information processing method provided by the present application is first introduced.

[0044] The information processing system provided by the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0045] Figure 1 This is a schematic diagram of the structure of an information processing system provided by an embodiment of the present application. Figure 1 As shown, the information processing system may include a server 110 and a client 120 , and a network 130 connecting the server and the client.

[0046] In one example, server 110 may be a processor, etc. Client 120 may be, but is not limited to, a personal computer (PC), a smartphone, a tablet computer, a personal digital assistant (PDA), etc. A client may also be any smart home device. Network 130 may be a wired or wireless network.

[0047] It should be noted that Figure 1 This is just an example. The number of the above-mentioned clients 120 can be set according to needs and is not limited here.

[0048] It should be noted that the server 110 and the client 120 together constitute a blockchain network. The server 110 and the client 120 are multiple nodes in the blockchain network. Each node finds the one that stores the blockchain ledger data, that is, the initial block, and multiple blockchain forks connected to the initial block (the specific blockchain structure can be referred to Figure 4 structure shown).

[0049] In this application, the server obtains the information notification task to be sent to the client; based on the information notification task, it detects whether each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client. When it is determined that the target blockchain fork node stores an expired information notification task, the expired information notification task is backed up and the expired information notification task in the target blockchain fork node is deleted, thereby maintaining the lightweight of the blockchain and reducing the burden on the blockchain.

[0050] In order to understand the working principle of the information processing system in more detail, the embodiment of the present application provides an information processing method, the execution subject of the information processing method can be Figure 1 Information processing system in . Figure 2 As shown, the information processing method provided in the embodiment of the present application may include steps 210 to 280.

[0051] Step 210: When the server needs to send an information notification task to the client, it determines the proxy node.

[0052] The information notification task may be a task sent to the client, and may include: a client identifier sent to the client, and a notification message sent to the client.

[0053] In one example, taking the client as a smart home device, the information notification task may be to notify which smart home device to control and information on how to control the smart home device (for example, information on turning on a certain smart home device).

[0054] In some embodiments of the present application, when the server needs to send control information to the client, it can first elect a proxy node through a protocol similar to Delegated Proof of Stake (DPOS), and then the proxy nodes of the blockchain can confirm through a consensus protocol that one of the nodes writes a message to the blockchain block in a transaction manner or performs a blockchain cleanup operation.

[0055] In some embodiments of the present application, when an information notification task needs to be sent to a client, it is necessary to identify a proxy node, obtain the information notification task that the proxy node wants to send to the client, and then generate a blockchain fork node after the initial block of the blockchain based on the proxy node according to the information notification task.

[0056] In some embodiments of the present application, the proxy node may be a server.

[0057] Step 220: Based on the information notification task, the server generates a blockchain fork node after the initial block of the blockchain, and detects whether each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client.

[0058] Among them, the blockchain includes an initial block and multiple blockchain fork nodes, each blockchain fork node corresponds to an information notification task, and each blockchain fork node is connected to the initial block.

[0059] The expired information notification task may be an information notification task that has already been responded to by the client.

[0060] In one example, if the server has sent an information notification task to the client to open the client, and the client responds to the information notification task and opens the client, then the information notification task is an information notification task that has been responded to, that is, an expired information notification task.

[0061] In some embodiments of the present application, before writing an information notification task into the blockchain, it is possible to detect whether each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client.

[0062] In some embodiments of the present application, after the server writes the information notification task into the blockchain fork, each client will obtain the information notification task through the synchronization mechanism of the blockchain network. After the client responds to the information notification task, it will generate a response message, generate a new block for the response message, and connect the new block to the end of the corresponding blockchain fork. Through the synchronization mechanism of the blockchain network, the new block will be synchronized to the server. In this way, the server can determine whether the information notification task corresponding to the blockchain fork has been processed by the client by checking whether the response message is recorded in each block of the blockchain fork. If a response message is recorded in a block of a blockchain fork, it means that the information notification task has been processed by the client, and then it means that the information notification task has expired.

[0063] Step 230: When the server determines that an expired information notification task is stored in the target blockchain fork node, the server backs up the expired information notification task and deletes the expired information notification task in the target blockchain fork node.

[0064] The target blockchain fork node may be any one or any several of the blockchain fork nodes.

[0065] In some embodiments of the present application, when it is determined that each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client, the expired information notification task in the target blockchain fork node is deleted, thereby ensuring the lightweight of the blockchain.

[0066] Step 240: When the server determines that there is no expired information notification task in the blockchain, the server writes the information notification task into the established blockchain fork node.

[0067] Step 250: The server synchronizes the blockchain among all blockchain nodes through the blockchain network.

[0068] In some embodiments of the present application, after the information notification task is written into the blockchain fork node, the information notification task can be broadcast synchronously among all blockchain nodes so that all blockchain nodes can have the information notification task.

[0069] Step 260: The client monitors the information notification task in the blockchain. When it is determined that the information notification task in the blockchain is updated, the client obtains the notification message corresponding to the client from each blockchain fork node based on the client identifier in each blockchain fork node.

[0070] Step 270: Based on the notification message, the client performs an operation corresponding to the notification message and obtains operation result information.

[0071] Step 280: The client sends the operation result information to the blockchain for storage.

[0072] In an embodiment of the present application, the server obtains an information notification task to be sent to the client; based on the information notification task, it detects whether each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client. When it is determined that the target blockchain fork node stores an expired information notification task, the expired information notification task is backed up and the expired information notification task in the target blockchain fork node is deleted, thereby maintaining the lightweight of the blockchain and reducing the burden on the blockchain.

[0073] The information processing method provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0074] Figure 3 This is a flow chart of an information processing method provided by an embodiment of the present application. The execution subject of the information processing method can be Figure 1 Server in.

[0075] like Figure 3 As shown, the information processing method provided in the embodiment of the present application may include steps 310 to 320.

[0076] The information processing method provided in the embodiments of the present application is described in detail below.

[0077] Step 310: Check whether each blockchain fork node in the blockchain has an expiration information notification task that has been responded to by the client.

[0078] In some embodiments of the present application, this step is the same as the server detecting in step 220 above whether each blockchain fork node in the blockchain has an expiration information notification task that has been responded to by the client, and will not be repeated here.

[0079] In some embodiments of the present application, in order to accurately determine when to detect whether each blockchain fork node in the blockchain has an expiration information notification task that has been responded to by the client, before step 310, the above-mentioned information processing method may further include:

[0080] Acquire an information notification task, wherein the information notification task is a task for notifying a client of information;

[0081] Correspondingly, step 310 may specifically include:

[0082] Based on the information notification task, detect whether each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client.

[0083] In some embodiments of the present application, the task of obtaining information notification may be consistent with the task of the server obtaining notification information to the client in the above step 210, which will not be repeated here.

[0084] In some embodiments of the present application, when an information notification task is obtained, it can be determined whether each blockchain fork node in the blockchain needs to be checked for an expired information notification task that has been responded to by the client.

[0085] In an embodiment of the present application, when an information notification task is obtained, it is determined whether each blockchain fork node in the detection blockchain has an expired information notification task that has been responded to by the client. In this way, the detection time of the expired information notification task can be accurately determined. In this way, the user can intuitively view when to start detecting whether there is an expired information notification task in the blockchain fork node, thereby improving the user experience.

[0086] In some embodiments of the present application, before receiving the information notification task, it is necessary to identify a proxy node and obtain the information notification task to be sent to the client by the proxy node. Therefore, before step 310, the above-mentioned information processing method may further include:

[0087] Obtaining attribute information of at least one server and a preset weight of each server;

[0088] Determine the target server based on the attribute information and preset weights of each server;

[0089] Correspondingly, step 320 may specifically include:

[0090] Get the information notification task to be sent to the client based on the target server.

[0091] The attribute information may at least include: an Internet Protocol (IP) address of the server, identification information of the server, and memory information of the server.

[0092] In some embodiments of the present application, the identification information here may be information identifying a server, such as a code of the server.

[0093] The preset weight may be a pre-set weight of each server, which may be set according to user needs and is not limited here.

[0094] In some embodiments of the present application, based on a received information notification task, the voting block in the blockchain can include attribute information of each block and a preset weight of each server. Based on the attribute information and preset weight of each server written in the voting block, a target server can be determined. In this way, an information notification task to be sent to the client can be obtained based on the target server.

[0095] In some embodiments of the present application, the number of target servers may be one or more.

[0096] In some embodiments of the present application, after the target server is determined, the current timestamp can be recorded. When some target servers are unable to provide services or the time expires, the target server can initiate a new round of target server selection, and then select the target server based on the attribute information of the existing servers and the preset weights, and then write it into the voting block.

[0097] In an embodiment of the present application, by obtaining the attribute information of at least one server and the preset weight of each server; based on the attribute information and the preset weight of each server, the target server is determined, so that the information notification task to be sent to the client can be obtained based on the target server, rather than using all servers to obtain the information notification task to be sent to the client, thereby saving the number of servers.

[0098] In some embodiments of the present application, the information notification task may include: a client identifier sent to the client, and a notification message sent to the client.

[0099] The client identifier may be an identifier of the client, for example, a code of the client.

[0100] The notification information may be information sent to the client, for example, may be control information for controlling the client.

[0101] In some embodiments of the present application, after step 310, the above-mentioned information processing method may further include:

[0102] Constructing the first blockchain fork node corresponding to the information notification task;

[0103] The client identifier and the notification message are stored in the first blockchain fork node.

[0104] Among them, the first blockchain fork node can be a fork node generated after the initial block of the blockchain based on the received information notification task.

[0105] In some embodiments of the present application, a blockchain may include an initial block and multiple blockchain fork nodes, each blockchain fork node corresponds to an information notification task, and each blockchain fork node is connected to the initial block.

[0106] To facilitate understanding of blockchain, some relevant information about the blockchain in the embodiments of this application is introduced below:

[0107] The structure of the blockchain in the embodiment of this application is as follows Figure 4 As shown, the blockchain 400 has multiple blocks. They can be the initial block 410, the voting block 420, and other blocks 430 (i.e. Figure 4 Each block consists of a block header and a block body.

[0108] In some embodiments of the present application, the blockchain structure is shown in Table 1 below:

[0109] Table 1

[0110]

[0111] In some embodiments of the present application, the structure of the block header in the blockchain is shown in Table 2 below:

[0112] Table 2

[0113]

[0114] In some embodiments of the present application, the structure of the block body of the voting block is shown in Table 3 below:

[0115] Table 3

[0116]

[0117] In some embodiments of the present application, the structure of the block body of a common block is shown in Table 4 below:

[0118] Table 4

[0119]

[0120] In some embodiments of the present application, the numbers in the middle columns of Tables 1-4 above represent the bytes corresponding to the row. For example, the number "4" corresponding to the block number in Table 1 means that the block number occupies 4 bytes.

[0121] In an embodiment of the present application, by constructing a first blockchain fork node corresponding to the information notification task, the client identifier and the notification message are stored in the first blockchain fork node, thereby improving the original structure of the blockchain, generating a blockchain fork node after the initial block, and making one blockchain fork node correspond to one information notification task, so that expired information notification tasks can be effectively cleaned up later.

[0122] In some embodiments of the present application, since the memory for the notification information sent to the client is too large, this may result in an excessive amount of notification information being stored in the blockchain fork node, causing an oversaturation problem in the blockchain fork node. To avoid excessive load on a blockchain fork node, before constructing the first blockchain fork node corresponding to the information notification task, the information processing method may further include:

[0123] Get the memory information of the information notification task;

[0124] Based on the memory information, the information notification task is split into at least two sub-information notification tasks;

[0125] The step of constructing a first blockchain fork node corresponding to the information notification task includes:

[0126] Constructing a number of first blockchain fork nodes corresponding to the number of sub-information notification tasks;

[0127] The storing of the client identifier and the notification message in the first blockchain fork node includes:

[0128] For each sub-information notification task, the sub-information notification task and the client identifier are stored in the target first blockchain fork node.

[0129] The memory information may be the memory occupied by the information notification task.

[0130] The sub-information notification task may be formed by splitting the information notification task.

[0131] The target first blockchain fork node may be any one of multiple first blockchain fork nodes.

[0132] In an example, if the memory information of the information notification task B sent to client A is 400 bits, then according to the memory information, the information notification task B can be split into two sub-information notification tasks (the specific number of sub-information notification tasks for splitting the information notification task B can be set according to user needs and is not limited here), for example, sub-information notification task B1 and sub-information notification task B2 respectively, and then a number of first blockchain fork nodes corresponding to the number of sub-information notification tasks B1 and sub-information notification tasks B2 can be constructed, that is, two first blockchain fork nodes can be constructed, namely the first blockchain fork node C1 and the first blockchain fork node C2, and then the identifier of the client A and the sub-information notification task B1 are stored in the first blockchain fork node C1 (that is, the target first blockchain fork node), and the identifier of the client A and the sub-information notification task B2 are stored in the first blockchain fork node C2 (that is, the target first blockchain fork node).

[0133] In an embodiment of the present application, memory information of an information notification task is obtained; then, based on the memory information, the information notification task is split into at least two sub-information notification tasks, and a number of first blockchain fork nodes corresponding to the number of sub-information notification tasks is constructed. For each sub-information notification task, the sub-information notification task and the client identifier are stored in the target first blockchain fork node. In this way, information notification tasks with too much memory can be stored separately to avoid the problem of excessive load on a certain blockchain fork node.

[0134] In some embodiments of the present application, in order to maintain the security of the information notification task stored in the blockchain fork node, storing the client identifier and the notification message in the first blockchain fork node may specifically include:

[0135] Encrypt the notification message based on the client's public key to obtain an encrypted notification message;

[0136] The client identifier and the encrypted notification message are stored in the first blockchain fork node.

[0137] In some embodiments of the present application, if the notification message is from a single client, the client's public key and the public and private keys of the proxy node may be used to encrypt the notification message, and the encrypted notification message and the client's identifier may be stored in the first blockchain fork node. If the notification message is from multiple clients, the public key of each client and the public and private keys of the proxy node may be used to encrypt the notification message corresponding to each client, and the encrypted notification message and the identifier of each client may be stored in the first blockchain fork node. That is, the identifiers of multiple clients and the encrypted notification messages of multiple clients are stored in the first blockchain fork node.

[0138] In an embodiment of the present application, the notification message is encrypted based on the public key of the client to obtain an encrypted notification message, and the client identifier and the encrypted notification message are stored in the first blockchain fork node. In this way, batch security authentication is performed in each client through the public key encrypted notification message contained in the blockchain structure, thereby improving the security authentication efficiency between the server and each client.

[0139] In some embodiments of the present application, in order to improve the computing resources of the server, after storing the client identifier and the notification message in the first blockchain fork node, the above-mentioned information processing method may further include:

[0140] Based on the blockchain protocol, the information notification task is broadcast to each client connected to the blockchain.

[0141] In an embodiment of the present application, the information notification task is broadcast to each client connected to the blockchain based on the blockchain protocol, that is, the information notification task is broadcast to each client through the blockchain network, rather than the server pushing it to each client one by one. This saves computing resources on the server side, improves the efficiency of information push, and realizes the decentralization of the system through the network result characteristics of the blockchain.

[0142] Step 320: When it is determined that an expired information notification task is stored in the target blockchain fork node, the expired information notification task in the target blockchain fork node is deleted.

[0143] The target blockchain fork node may be any one of the blockchain fork nodes.

[0144] In some embodiments of the present application, when it is determined that an expired information notification task is stored in the target blockchain fork node, the expired information notification task in the target blockchain fork node can be deleted, thereby ensuring that the amount of blockchain data remains lightweight during the notification process.

[0145] In some embodiments of the present application, when it is determined that an expired information notification task is stored in the target blockchain fork node, the expired information notification task can be backed up and deleted from the target blockchain fork node. This allows the expired information notification task to be retrieved later if desired, improving the user experience.

[0146] In some embodiments of the present application, in order to understand the workflow of the server in more detail, the present application provides another implementation of an information processing method, such as Figure 5 As shown, the information processing method may include steps 510 to 560.

[0147] Step 510: elect a proxy node based on the voting block.

[0148] In some embodiments of the present application, step 510 is consistent with the above embodiment in which the voting block selects the target server based on the attribute information of each block and the preset weight of each block, and will not be repeated here.

[0149] Step 520: Based on the received information notification task, check whether each blockchain fork node in the blockchain has an expired information notification task that has been responded to by the client. If not, execute step 530; if so, execute step 560.

[0150] In some embodiments of the present application, step 520 is consistent with step 310 in the above embodiment and will not be repeated here.

[0151] Step 530: Based on the type of the information notification task, the information notification task is encrypted using the public and private keys of the server and the public key of the client, and the encrypted information notification task is written into the blockchain fork node.

[0152] In some embodiments of the present application, the type of an information notification task may be whether the information notification task is a single-client information notification task or a multi-client information notification task. If the information notification task is a single-client information notification task, the information notification task may be encrypted using the client's public key and the public and private keys of the proxy node, and the encrypted information notification task may be stored in the blockchain fork node. If the information notification task is a multi-client information notification task, the information notification task corresponding to each client may be encrypted using the public key of each client and the public and private keys of the proxy node, and the encrypted information notification task may be stored in the blockchain fork node.

[0153] Step 540: broadcast the information notification task to each client.

[0154] In some embodiments of the present application, step 540 is consistent with broadcasting the information notification task to each client connected to the blockchain based on the blockchain protocol in the above embodiment, and will not be repeated here.

[0155] Step 550: Determine whether there are any information notification tasks that need to be written into the blockchain. If yes, return to step 520; if no, end.

[0156] Step 560: Back up the expired information notification task and delete the expired information notification task in the blockchain fork node.

[0157] In some embodiments of the present application, step 560 is consistent with step 320 in the above embodiment and is not described here in detail.

[0158] The above embodiment describes the new processing method of the present application with the server as the execution subject. The following describes the information processing method of the present application with the client as the execution subject. For the sake of brevity, the nouns in the embodiments of the present application that are consistent with those in the above embodiment will not be repeated here.

[0159] Figure 6 is a flowchart of another information processing method according to an exemplary embodiment. The execution subject of the information processing method may be Figure 1 The client in .

[0160] like Figure 6 As shown, the information processing method may include the following steps 610 to 640.

[0161] Step 610: Monitor the information notification task in the blockchain.

[0162] Among them, the blockchain may include an initial block and multiple blockchain fork nodes, each blockchain fork node corresponds to an information notification task, and each blockchain fork node is connected to the initial block.

[0163] Step 620: When it is determined that the information notification task in the blockchain is updated, based on the client identifier in each blockchain fork node, a notification message corresponding to the client is obtained from each blockchain fork node.

[0164] In some embodiments of the present application, determining that an information notification task in the blockchain has been updated may be determining that there is a new information notification task in the blockchain, and then obtaining a notification message corresponding to the client from each blockchain fork node based on the client identifier in each blockchain fork node.

[0165] Step 630: Based on the notification message, perform the operation corresponding to the notification message and obtain operation result information.

[0166] The operation result information may be the result information obtained after the client performs the operation corresponding to the notification message according to the notification message, that is, whether the client performs the operation corresponding to the notification message and the result after the operation.

[0167] In one example, if the notification message is to open the client, the client may open the client according to the notification message, and the client is opened at this time (ie, operation result information).

[0168] In some embodiments of the present application, based on the notification message, the client may perform an operation corresponding to the notification message, and thereby obtain operation result information.

[0169] In some embodiments of the present application, in order to ensure that the client can perform the operation corresponding to the notification message, before step 630, the above-mentioned information processing method may further include:

[0170] Decrypt the notification message based on the client's private key;

[0171] Correspondingly, step 630 may specifically include:

[0172] Based on the decrypted notification message, an operation corresponding to the decrypted notification message is performed to obtain operation result information.

[0173] In an embodiment of the present application, after obtaining the notification message, the notification message is decrypted using the client's private key, and then the operation corresponding to the decrypted notification message is performed to obtain the operation result information. This ensures that the client can perform the corresponding operation and ensures the security of the notification message.

[0174] Step 640: Store the operation result information in the blockchain.

[0175] In an embodiment of the present application, the client monitors the information notification tasks in the blockchain. When the information notification tasks in the blockchain are updated, the client can obtain the notification message corresponding to the client from each blockchain fork node based on the client identifier in each blockchain fork node, and then perform the operation corresponding to the notification message to obtain the operation result information, and store the operation result information in the blockchain, thereby improving the efficiency of the client in receiving information notification tasks.

[0176] In some embodiments of the present application, determining that the information notification task in the blockchain is updated may also mean that the information notification task in the blockchain is deleted. In the case where the information notification task in the blockchain is updated and the information notification task in the blockchain is deleted, the above-mentioned information processing method may further include:

[0177] When it is determined that the expired information notification task in the target blockchain fork node in the blockchain is deleted, the file corresponding to the expired information notification task in the client is deleted.

[0178] In an embodiment of the present application, if it is determined that the expired information notification task in the target blockchain fork node in the blockchain is deleted, the file corresponding to the expired information notification task in the client is deleted, thereby reducing the resources of the client and ensuring the lightweight nature of the client.

[0179] In some embodiments of the present application, since the server and client constitute a blockchain network, the server and client are connected via a network, i.e., a communication protocol exists between the server and client. Thus, when a server node deletes an expired information notification task in a blockchain fork, the message "the server node has deleted the expired information notification task in the blockchain fork" can be broadcast to the client based on the communication protocol between the server and client. The client can then promptly check that the server node has deleted the expired information notification task in the blockchain fork, and can then delete the file corresponding to the expired information notification task based on the received broadcast information.

[0180] Specifically, when a server broadcasts the message "The server node deleted the expiration notification task in a blockchain fork" to a client, it can also broadcast the specific expiration notification task that the server node deleted. That is, the specific blockchain fork that the server deleted can be sent to the client via the broadcast message. Furthermore, the broadcast message can include identification information of the deleted blockchain fork, so that the client can delete the file corresponding to the expiration notification task based on the received broadcast message.

[0181] In some embodiments of the present application, in order to understand the workflow of the client in more detail, the present application provides another implementation of an information processing method, such as Figure 7 As shown, the information processing method may include steps 710 to 750.

[0182] Step 710: Monitor the information notification task in the blockchain.

[0183] In some embodiments of the present application, step 710 is consistent with step 610 in the above embodiment and will not be repeated here.

[0184] Step 720: Determine whether the information notification task in the blockchain has been updated. If so, execute step 730; if not, return to step 710.

[0185] Step 730: Determine whether the update is a deletion of the expired information notification task in the blockchain. If so, execute step 740; if not, execute step 750.

[0186] Step 740: Delete the file corresponding to the expiration information notification task in the client.

[0187] Step 750: Obtain the notification message from the blockchain, decrypt the notification message according to the type of the notification message, execute the decrypted notification message on the client, obtain the operation result information, and send the operation result information to the blockchain for storage.

[0188] In some embodiments of the present application, the type of notification message may be whether the notification message is for a single client or for multiple clients. If the notification message corresponds to a single client, the notification message is decrypted using the client's private key or the proxy node's public key, and then the single client executes the decrypted notification message and sends the operation result information to the blockchain for storage. If the notification message corresponds to multiple clients, the notification message is decrypted using the private keys of the multiple clients or the public keys of the proxy node, and then the multiple clients respectively execute their corresponding notification messages, obtain their corresponding operation result information, and then store their corresponding operation result information in the blockchain.

[0189] The information processing method of the embodiment of the present application can be widely applied to Internet of Things scenarios, such as smart homes, electricity meter reading, and municipal facility management.

[0190] In an embodiment of the present application, the blockchain data cleaning function of the server can keep the overall data scale of the blockchain small, so the block design no longer saves the check tree of the conventional blockchain for verifying the entire block, thereby ensuring that all blocks maintain the full amount of blockchain data and that data is efficiently synchronized in the blockchain network through broadcasting; and the block format specially designed for batch information notification tasks and the parallel support capabilities of blockchain fork nodes achieve the effect of improving the interaction efficiency of information notification tasks.

[0191] In the embodiments of the present application, the technical characteristics of security and information sharing between nodes of the blockchain are utilized to realize batch security authentication between client nodes; through the blockchain data cleaning function, the data volume of the blockchain is maintained at a small scale, and the data consistency capability of the blockchain is utilized to realize the rapid delivery of information notification tasks to the Internet of Things devices (i.e., each client) through the blockchain network broadcast, which solves the problem that the conventional message sending method must use the server to push one by one, and when the system devices (i.e., clients) increase infinitely, the centralized server cannot support it. At the same time, it also solves the problem of security authentication and information interaction efficiency of communication between each Internet of Things terminal (i.e., each client) in the traditional Internet of Things system, and realizes decentralization, solving the bottleneck and resource problems of centralization.
