Description

Technical Field

[0001] This application relates to the field of blockchain technology, and in particular, to a data processing method, apparatus, device, and storage medium based on blockchain. Background Art

[0002] Currently, with the development of Internet technology, the usage frequency of various social application programs is getting higher and higher, so the frequency of using social application programs to transmit business data is getting higher and higher. In the current process of transmitting business data, the business data needs to be sent to a central server, and the central server forwards the business data to the target object. That is to say, if the central server is illegally invaded, all the business data forwarded by the central server will be leaked, increasing the risk of business data transmission. Moreover, when the amount of business data to be transmitted increases, the amount of business data that the central server needs to forward increases accordingly, resulting in an increased load on the central server. Furthermore, when the load of the central server is too high, the newly added business data needs to queue up during transmission, reducing the transmission efficiency of the social application program for transmitting business data.

[0054] On the one hand, the present application provides a computer device, including: a processor, a memory, and a network interface;

Among them, the above-mentioned network interface is used to provide a data communication function, the above-mentioned memory is used to store a computer program, and the above-mentioned processor is used to call the above-mentioned computer program so that the computer device executes the method in the embodiment of the present application.

[0056] On the one hand, the embodiment of the present application provides a computer-readable storage medium, in which a computer program is stored, and the computer program is suitable for being loaded and executed by a processor to execute the method in the embodiment of the present application.

[0057] On the one hand, the embodiment of the present application provides a computer program product or a computer program.

This process avoids the need for forwarding in the central server when transmitting service data. That is, even if the central server is illegally invaded, the service data will not be leaked, ensuring the security during the transmission of service data. Moreover, the first digital certificate, the second digital certificate, and the target node address provide the initiating service node with the ability to communicate with the target service node. Further, after the consensus processing is successfully carried out through the consensus network in the embodiments of the present application, point-to-point communication can be performed based on the obtained second digital certificate and target node address, avoiding the service data forwarding process of the central server. Thus, there is no problem of excessive load on the central server, that is, the transmission pressure of service data will be distributed to each service node in the blockchain network, so that for the time spent in the transmission process of service data, the service data queuing time will not be too long due to excessive load, improving the transmission efficiency of the social application program for transmitting service data.

[0070] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0071] It can be understood that in the specific implementation manners of the present application, for data related to objects or users (such as payment data), when the following embodiments of the present application are applied to specific products or technologies, user permission or consent needs to be obtained, and the collection, use, and processing of relevant data need to comply with relevant laws, regulations, and standards in the relevant regions.

[0072] The solution provided by the embodiment of the present application relates to blockchain technology, and the specific process will be described through the following embodiments.

[0073] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a blockchain network provided by an embodiment of the present application. As Figure 1 shown, the blockchain network may include, but is not limited to, a distributed network corresponding to blockchain services. The blockchain network may include multiple blockchain nodes, and the multiple blockchain nodes may specifically include blockchain node 10a, blockchain node 10b, blockchain node 10c, blockchain node 10d, …, blockchain node 10n. For example, a blockchain node may be a client or a server in the distributed network corresponding to blockchain services. Among them, when each blockchain node is working properly, it can receive data sent from the outside world and perform block on-chain processing based on the received data, or send data to the outside world. To ensure data intercommunication between blockchain nodes, there may be data connections between each blockchain node. For example, there is a data connection between blockchain node 10a and blockchain node 10b, a data connection between blockchain node 10a and blockchain node 10c, and a data connection between blockchain node 10b and blockchain node 10c.

[0074] It can be understood that data or blocks can be transmitted between blockchain nodes through the above data connections. The blockchain network can implement data connections between blockchain nodes based on node identifiers. For each blockchain node in the blockchain network, there is a corresponding node identifier, and each of the above blockchain nodes can store the node identifiers of other blockchain nodes that are connected to itself, so as to broadcast the obtained data or generated blocks to other blockchain nodes according to the node identifiers of other blockchain nodes in the future. For example, blockchain node 10a can maintain a node identifier list as shown in Table 1, and this node identifier list stores the node names and node identifiers of other nodes:

[0075] Table 1

[0076] Node Name Node Identifier Node 10a AAA.AAA.AAA.AAA Node 10b BBB.BBB.BBB.BBB Node 10c CCC.CCC.CCC.CCC Node 10d DDD.DDD.DDD.DDD … … Node 10n EEE.EEE.EEE.EEE

[0077] Among them, the node identifier may be an Internet Protocol (IP) address for interconnection between networks and any other information that can be used to identify nodes in the blockchain network. Only the IP address is used as an example in Table 1 for illustration. For example, blockchain node 10a can send blockchain data (for example, encrypted data packaged in block format) to blockchain node 10b through the node identifier BBB.BBB.BBB.BBB, and blockchain node 10b can determine that this information is sent by blockchain node 10a through the node identifier AAA.AAA.AAA.AAA.

[0078] In a blockchain, before a block is added to the blockchain, the block must go through consensus among the consensus nodes in the blockchain network, and can be added to the blockchain only after the consensus is passed. It can be understood that when the blockchain is used in some scenarios of commercial institutions, not all participating nodes in the blockchain (i.e., the blockchain nodes in the above-mentioned blockchain network) have sufficient resources and necessity to become the consensus nodes of the blockchain. For example, in Figure 1 In the blockchain network shown, blockchain nodes 10a, 10b, 10c, and 10d can be used as the consensus nodes in this blockchain network. The consensus nodes in the blockchain network participate in consensus, that is, conduct consensus on the block (including a batch of transactions), that is, vote on the block; non-consensus nodes do not participate in consensus, but will help spread the block and voting messages, and synchronize the status with each other, etc.

[0079] It can be understood that the method provided in the embodiments of the present application can be executed by a computer device, and the computer device includes but is not limited to the above-mentioned blockchain nodes (which can be a social client in the embodiments of the present application). Among them, in the embodiments of the present application, the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud databases, cloud services, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. Among them, the above-mentioned client can be an electronic device, including but not limited to mobile phones, tablets, desktop computers, laptop computers, palmtop computers, in-vehicle devices, augmented reality / virtual reality (AR / VR) devices, head-mounted displays, smart TVs, wearable devices, smart speakers, digital cameras, cameras, and other mobile internet devices (MID) with network access capabilities, or terminal devices in scenarios such as trains, ships, and flights. In the embodiments of the present application, the client can include a resource client.

[0080] It can be understood that the embodiments of the present application can be applied to various scenarios, including but not limited to scenarios such as cloud technology, artificial intelligence, and intelligent transportation. For example, the blockchain node system can conduct consensus on some driving behavior data, road trajectory data, etc. sent by in-vehicle terminals, and store them on the blockchain after the consensus is passed.

[0081] It can be understood that in a specific embodiment, the initiating business node (such as can be Figure 1The blockchain node 10a) therein can obtain the first digital certificate corresponding to the target object. Among them, the initiating service node includes a social client, and the target object refers to the object logging in to the social client. Further, the initiating service node can obtain the associated social identification information corresponding to the object to be added (which can be the object identity information of the object to be added, such as the user name or user account). The first digital certificate, the associated social identification information, and the social contract identifier are encapsulated into a social addition request, and the social addition request is sent to the consensus network so that the consensus network can call the social smart contract through the social contract identifier in the social addition request, and obtain the response result of the social addition request feedback by the target service node (such as the blockchain node 10b) in Figure 1 therein). The target service node refers to the service node corresponding to the associated social identification information. Further, when both the social addition request and the response result are successfully consensus in the consensus network, and the response result is an approval to add message, obtain the target node address and the second digital certificate corresponding to the target service node from the service execution result returned by the consensus network (that is, the social addition request can be regarded as a transaction to be chained, and the service execution result can be obtained by executing this transaction to be chained). The first digital certificate, the second digital certificate, and the target node address are used to provide the initiating service node with the ability to communicate with the target service node.

[0082] Among them, the social client can include an interface for interacting with the blockchain network. Specifically, the social client can be used to implement the resource management service function related to social networking, and based on this resource management service function, establish a communication connection with the decentralized application client. Briefly speaking, the social client is a tool for managing and storing user digital resources. For example, digital resources can be transferred to other accounts based on the social client, or digital resources transferred from other accounts can be received based on the social client. The social client can be a hardware device or a software program. In this application, the social client of the target object can establish a communication connection with the decentralized application client to implement related operations such as authorized login of the target object. It can be understood that with the wide deployment of various decentralized applications on the blockchain and the increase in user activities on the blockchain, when ordinary users use decentralized applications, they can use the blockchain key management tool for login. The address in the blockchain key management tool corresponds to a user on the blockchain, and the decentralized application can obtain the user address from the key management tool through some interfaces.

[0083] Further, please refer to Figure 2 , Figure 2 which is a schematic diagram of a scenario for sending a social addition request provided by an embodiment of this application. As shown in Figure 2As shown in the figure, an embodiment of the present application provides a data processing method based on a blockchain. This method is executed by the initiating service node 24A in the blockchain network, and the initiating service node 24A may include a social client. Specifically, the initiating service node 24A obtains the first digital certificate 241N corresponding to the target object 23P. Herein, the target object 23P refers to the object logging in to the social client. Further, the initiating service node 24A may obtain the associated social identification information 242A corresponding to the object to be added. Further, the initiating service node 24A may encapsulate the first digital certificate 241N, the associated social identification information 242A, and the social contract identifier 243S into a social addition request 2400Q, and send the social addition request 2400Q to the consensus network 25S, so that the consensus network 25S calls the social smart contract through the social contract identifier 243S in the social addition request 2400Q, and obtains the response result of the social addition request 2400Q feedback by the target service node 26P through the social smart contract. Herein, the target service node 26P refers to the service node corresponding to the associated social identification information. Specifically, the target service node may include the target service node 26P, the target service node 27P, the target service node 28P,..., the target service node yP, etc., where y is a positive integer. Further, when both the social addition request 2400Q and the response result are successfully consensus in the consensus network 25S, and the response result is an approval message for addition, obtain the target node address and the second digital certificate corresponding to the target service node 26P from the business execution result returned by the consensus network 25S. The first digital certificate 241N, the second digital certificate, and the target node address are used to provide the initiating service node 24A with the ability to communicate with the target service node 26P.

[0084] Specifically, the consensus service nodes in the consensus network 25S can obtain the social addition request 2400Q sent by the initiating service node. It should be understood that the consensus service nodes can send the social addition request 2400Q to other consensus service nodes in the consensus network 25S, so that each consensus service node in the normal state can jointly conduct a consensus vote on the social addition request 2400Q. If the consensus on the social addition request 2400Q is successful, the consensus service node can send the social addition request 2400Q to the target service node 26P. Further, the consensus service node can receive the response result from the target service node 26P. Further, the consensus service node can send the response result to other consensus service nodes in the consensus network 25S, so that each consensus service node in the normal state can jointly conduct a consensus vote on the response result. When both the social addition request 2400Q and the response result are successfully consensus in the consensus network 25S, and the response result is an approval message for addition, the initiating service node 24A can obtain the target node address and the second digital certificate corresponding to the target service node 26P from the service execution result returned by the consensus network 25S. Further, the initiating service node 24A can send a communication message for communication to the target service node 26P through the target node address and the second digital certificate corresponding to the target service node 26P. That is to say, the initiating service node 24A can communicate with the target service node 26P through the target node address and the second digital certificate corresponding to the target service node 26P for communication processing.

[0085] Specifically, the social addition request (such as the social addition request 2400Q) can be understood as a business transaction. Among them, generally speaking, a business transaction can be understood as the computer term transaction. Correspondingly, in detail, a business transaction refers to a data transfer on the blockchain. For example, a business transaction can include asset transfer between users of blockchain services, data transfer related to the blockchain, or transfer of executing a smart contract, etc. From another perspective, in terms of the components of a business transaction, a business transaction can include a business request and operations that need to be submitted to the blockchain network for execution, etc.

[0086] Among them, the initiating service node 24A can obtain the transaction execution result after a service transaction. Specifically, the transaction execution result refers to the processing result of the service transaction. For example, the transaction execution result may include that the service transaction is successful or the service transaction fails, etc. Optionally, the transaction execution result may further include the completion time of the service transaction, the failed steps of the service transaction, and the overall process data of the service transaction, etc. For example, the initiating service node 24A can obtain the transaction execution result through the remote procedure call transfer protocol (JSON-RPC) interface provided by the blockchain nodes in the blockchain node system 25S. Specifically, the initiating service node 24A can obtain components such as a social addition request, a service transaction response message, an interface version number, and a method name through the JSON-RPC interface. Among them, the social addition request may include the method name and request parameters of the social addition request. Further, the service transaction response message may include the specific information of the service transaction response object (such as information such as the nickname or address of the service transaction response object) and the service transaction error information. Among them, the interface version number may include version data for identifying the JSON-RPC interface. Correspondingly, the method name can be used to indicate the method to be called. Specifically, the response result may include a header, a payload, and a signature.

[0087] Further, please refer to Figure 3 , Figure 3 which is a schematic flowchart of a data processing method provided by an embodiment of the present application. As Figure 3 shown, this method can be executed by the initiating service node in the blockchain node system, and the initiating service node can be the above-mentioned Figure 1 shown blockchain node 10b, which is not limited here. For ease of understanding, an embodiment of the present application takes this method being executed by the initiating service node as an example for description. This data processing method may at least include the following steps S101-step S104:

[0088] Step S101, the initiating service node obtains the first digital certificate corresponding to the target object; the target object refers to the object logging in to the social client.

[0089] Specifically, the initiating service node can obtain the first digital certificate corresponding to the target object through a wired network or a wireless network. Among them, the initiating service node can obtain the first digital certificate corresponding to the target object through the communication network in wired transmission. Specifically, the communication network may include a communication system composed of a gateway device, a router, and a transmission cable. Among them, the initiating service node can obtain the first digital certificate corresponding to the target object through the Bluetooth function in wireless transmission.

[0090] Step S102, obtain the associated social identification information corresponding to the object to be added.

[0091] Specifically, the initiating service node can obtain the associated social identification information corresponding to the object to be added through the input control in the social application. Herein, the object to be added may refer to the object for which business data transmission is required. Optionally, the initiating service node can obtain the associated social identification information corresponding to the object to be added through wired transmission or wireless transmission. Among them, the initiating service node can obtain the associated social identification information corresponding to the object to be added through the communication network in wired transmission. Specifically, the communication network may include a communication system composed of a gateway device, a router, and a transmission cable. Among them, the initiating service node can obtain the associated social identification information corresponding to the object to be added through the Bluetooth function in wireless transmission. For example, the initiating service node can receive the associated social identification information corresponding to the object to be added in the communication network through the communication network. For another example, the initiating service node can also receive the associated social identification information corresponding to the object to be added through the AirDrop method in the Bluetooth function. Herein, the associated social identification information refers to the information associated with the object to be added and used for identification in the social process. Generally speaking, the associated social identification information may refer to the information related to the object to be added and capable of representing the object to be added. In detail, the associated social identification information may refer to the object identity information of the object to be added, such as the user name, user account, user identification, or user address, etc.

[0092] Step S103, encapsulate the first digital certificate, the associated social identification information, and the social contract identifier into a social addition request, and send the social addition request to the consensus network, so that the consensus network calls the social smart contract through the social contract identifier in the social addition request, and obtains the response result of the target service node for the social addition request through the social smart contract; the target service node refers to the service node corresponding to the associated social identification information.

[0093] Specifically, the initiating service node can encapsulate the first digital certificate, the associated social identification information, and the social contract identifier into a social addition request in sequence. Optionally, the initiating service node can encapsulate the first digital certificate, the associated social identification information, and the social contract identifier into a social addition request in a random order, and generate a social request tag based on this random order. Herein, the social request tag is used to determine the order among the first digital certificate, the associated social identification information, and the social contract identifier in the social addition request. Further, the initiating service node can send the social addition request to the consensus network, so that the consensus network calls the social smart contract through the social contract identifier in the social addition request, and obtains the response result of the target service node for the social addition request through the social smart contract. Herein, the target service node refers to the service node corresponding to the associated social identification information.

[0094] Step S104: When both the social addition request and the response result are successfully consensus in the consensus network and the response result is a message agreeing to the addition, obtain the target node address and the second digital certificate corresponding to the target service node from the service execution result returned by the consensus network; the first digital certificate, the second digital certificate, and the target node address are used to provide the initiating service node with the ability to communicate with the target service node.

[0095] Specifically, when both the social addition request and the response result are successfully consensus in the consensus network and the response result is a message agreeing to the addition, the initiating service node can perform data partitioning processing on the service execution result returned in the consensus network to obtain the target node address and the second digital certificate corresponding to the target service node. Briefly speaking, the initiating service node can perform data partitioning processing on different fields of the service execution result to obtain the target node address and the second digital certificate corresponding to the target service node. Optionally, when both the social addition request and the response result are successfully consensus in the consensus network and the response result is a message agreeing to the addition, the initiating service node can perform data extraction processing on the service execution result returned in the consensus network to obtain the target node address and the second digital certificate corresponding to the target service node. Briefly speaking, the initiating service node can perform data extraction processing on a specified field (such as the address field) to obtain the target node address and the second digital certificate corresponding to the target service node.

[0096] In detail, the initiating service node can obtain the address field identifier and the certificate field identifier in the service execution result. Further, the initiating service node can perform address field partitioning on the service execution result based on the address field identifier to obtain the target node address corresponding to the target service node. Correspondingly, the initiating service node can perform certificate field partitioning on the service execution result based on the certificate field identifier to obtain the second digital certificate corresponding to the target service node.

[0097] Further, the initiating service node (such as Figure 2 the initiating service node 24A shown) can pass through the target service node (such as Figure 2The target node address and the second digital certificate corresponding to the target service node 26P) shown are used to send a communication message for communication to the target service node. That is, the initiating service node can communicate with the target service node through the target node address and the second digital certificate corresponding to the target service node. Specifically, the initiating service node can establish a session communication channel with the target service node based on the target node address. Further, a communication window with the target service node is generated through the session communication channel, and a communication message for communication is sent through the communication window. It should be understood that the initiating service node can send one or more communication messages through the session communication channel. That is, the initiating service node can implement multi-round communication with the target service node through the session communication channel. Among them, one round of communication can at least include the initiating service node sending a communication message to the target service node and the initiating service node receiving a communication message sent by the target service node. Further, if no new communication message is detected in the communication window after exceeding a pre-set fixed time, the initiating service node can close the communication window and determine that this communication ends. That is, if no new communication message is detected in the communication window after exceeding a pre-set fixed time, it is determined that the communication process ends.

[0098] It can be understood that in the specific implementation of this application, data such as business transaction-related data, data corresponding to the initiating service node, and data associated with the target service node are involved. When the above and below embodiments of this application are applied to specific products or technologies, the collection and processing of relevant data should strictly comply with the requirements of relevant regional laws and regulations, obtain the informed consent or separate consent (or have a legal basis) of the personal information subject, and carry out subsequent data use and processing behaviors within the scope authorized by laws and regulations and the personal information subject. When it comes to face (or other biometric) recognition technology, the collection, use, and processing of relevant data should comply with the requirements of relevant regional laws and regulations. Before collecting face information, the information processing rules should be informed and the separate consent of the target object should be solicited (or have a legal basis), and the face information should be processed strictly in accordance with the requirements of laws and regulations and personal information processing rules, and technical measures should be taken to ensure the security of relevant data.

[0099] The embodiment of the present application obtains the first digital certificate corresponding to the target object by initiating a business node, which provides a perfect guarantee basis for the identity authentication of the target object. Further, by encapsulating the first digital certificate, the associated social identification information of the object to be added, and the social contract identification into a social adding request, the social adding request contains the identity authentication information. By authenticating the identity authentication information, the illegal intrusion of the object without identity authentication information can be reduced, and the security of the social adding request is improved. Further, by sending the social adding request to the consensus network, so that the consensus network calls the social smart contract through the social contract identification in the social adding request, the response result of the social adding request fed back by the target business node is obtained through the social smart contract; when the social adding request and the response result are both successfully agreed in the consensus network, and the response result is the consent to add message, the target node address and the second digital certificate corresponding to the target business node are obtained from the business execution result returned by the consensus network. Among them, the social friend adding process of the object to be added is carried out through the consensus network, and the security of the consensus network is used to ensure the security of the object to be added in the social friend adding process. Furthermore, through the first digital certificate, the second digital certificate and the target node address corresponding to the target business node, point-to-point communication is directly carried out between the initiating business node and the target business node, which avoids the process of forwarding in the central server when transmitting business data. In other words, even if the central server is illegally invaded, the business data will not be leaked, ensuring the security of the business data transmission process. Moreover, the first digital certificate, the second digital certificate and the target node address provide the initiating business node with the ability to communicate with the target business node. Further, after the consensus processing is successfully carried out through the consensus network, the embodiment of the present application can perform point-to-point communication based on the obtained second digital certificate and the target node address, avoiding the business data forwarding process of the central server, so that there is no problem of excessive load on the central server, that is, the transmission pressure of the business data will be shared on each business node in the blockchain network, so that in terms of the time spent in the transmission process of the business data, the business data queuing time will not be too long due to excessive load, thereby improving the transmission efficiency of the social application to transmit business data.

[0100] For further information, see Figure 4 , Figure 4 FIG. 1 is a flow chart of another data processing method provided in an embodiment of the present application. Figure 4 As shown, the method can be executed by an initiating service node in the blockchain node system, and the initiating service node can be the above Figure 1 The blockchain node 10b shown is not limited here. For ease of understanding, the present application embodiment takes the method executed by the initiating service node as an example for explanation, and the data processing method may at least include the following steps S201-S206:

[0101] Step S201, the initiating service node obtains the target social identification information corresponding to the target object logging in to the social client, generates a target private key and a target public key corresponding to the target private key.

[0102] Specifically, the initiating service node can perform data extraction processing on the data stored in the social client for the social client in the logged-in successful state to obtain the target social identification information corresponding to the target object logging in to the social client. Among them, the data stored in the social client can refer to the association information of the user object (i.e., the target object in the embodiments of the present application) entered into the social client by the user object logging in to the social client. Specifically, the association information can refer to the name of the user object or the code name of the user object, etc. That is to say, in the embodiments of the present application, the social identification information of the user object refers to the target social identification information corresponding to the target object. Among them, the initiating service node can obtain the association information of the user object through the information entry control when the user object of the social client logs in for the first time (i.e., when the user object registers in the social client).

[0103] Optionally, the initiating service node can obtain the target social identification information corresponding to the target object logging in to the social client through the input control included in the social client. That is to say, the initiating service node can directly obtain the content input by the target object logging in to the social client through the input control included in the social client, and determine the content input by the target object logging in to the social client as the target social identification information. For example, if the content input by the target object logging in to the social client obtained is "hahaha", then the target social identification information is determined as "hahaha". It should be understood that the content input by the target object logging in to the social client can include various formats of content, such as character format content, text format content, or image format content, and the specific format of the content is not limited here.

[0104] Specifically, the initiating service node can generate the target public key and the target private key by means of asymmetric encryption. Among them, asymmetric encryption refers to the process of encrypting and decrypting using a pair of asymmetric keys. Specifically, the initiating service node can use different target keys (i.e., the target public key and the target private key) respectively during the encryption process and the decryption process. Among them, the target public key refers to the public key associated with the target object generated by the initiating service node through asymmetric encryption. Correspondingly, the target private key refers to the private key associated with the target object generated by the initiating service node through asymmetric encryption. Specifically, the target public key can be broadcast and published, but the target private key is only stored locally at the target. For example, in a specific embodiment, the asymmetric encryption algorithm can include the RSA (Ron Rivest Adi Shamir Leonard Adleman) algorithm.

[0105] Further, the initiating service node may send the generated target public key to the certification authority, so that the certification authority receives the target public key, generates a first digital certificate based on the target public key, and sends the first digital certificate to the initiating service node. Herein, the certification authority refers to the institution that issues digital certificates (CA, Certificate Authority), that is, the institution that issues digital certificates.

[0106] Step S202: Send the target social identification information and the target public key to the certification authority, so that the certification authority performs identity authentication processing based on the target social identification information, and generates a first digital certificate based on the target public key when the identity authentication is passed.

[0107] Specifically, the initiating service node may send the target social identification information and the target public key to the certification authority through a wired network or a wireless network. Herein, the initiating service node may send the target social identification information and the target public key to the certification authority through the communication network in wired transmission. Correspondingly, the initiating service node may send the target social identification information and the target public key to the certification authority through the Bluetooth function in wireless transmission.

[0108] Step S203: Receive the first digital certificate sent by the certification authority.

[0109] Specifically, the initiating service node may receive the first digital certificate sent by the certification authority. Further, the initiating service node may perform certificate detection processing on the first digital certificate sent by the certification authority. Specifically, the initiating service node may determine whether the generated first digital certificate is correct by detecting the public key information in the first digital certificate.

[0110] In detail, the initiating service node may obtain the certificate service public key in the first digital certificate sent by the certification authority. Further, the initiating service node may compare the certificate service public key with the target public key. Herein, if the certificate service public key is the same as the target public key, it may be determined that the first digital certificate is legal. Correspondingly, if the certificate service public key is different from the target public key, an error prompt message is generated. Herein, the error prompt message is used to instruct the initiating service node to regenerate a new first digital certificate through the certification authority.

[0111] Step S204: Obtain the associated social identification information corresponding to the object to be added.

[0112] Specifically, for the specific process of the initiating service node obtaining the associated social identification information corresponding to the object to be added, please refer to the detailed description in step S102 above Figure 3 about the process of the initiating service node obtaining the associated social identification information corresponding to the object to be added, and details will not be elaborated here.

[0113] Step S205: Package the first digital certificate, associated social identification information, and social contract identification into a social addition request, and send the social addition request to the consensus network, so that the consensus network can call the social smart contract through the social contract identification in the social addition request, and obtain the response result of the target business node to the social addition request through the social smart contract; the target business node refers to the business node corresponding to the associated social identification information.

[0114] Specifically, for the specific process of the initiating business node packaging the first digital certificate, associated social identification information, and social contract identification into a social addition request, please refer to the above Figure 3 for the detailed description of the process in step S103 above where the initiating business node packages the first digital certificate, associated social identification information, and social contract identification into a social addition request, and details will not be elaborated here.

[0115] Furthermore, the consensus network can conduct consensus on the received social addition request in the consensus network. Specifically, the first consensus node in the consensus network can send the social addition request to other consensus nodes in the consensus network for consensus voting. If the consensus voting passes, the consensus on this social addition request is successful. Furthermore, the consensus network can call the social smart contract through the social contract identification in the social addition request, and obtain the response result of the target business node to the social addition request through the social smart contract. Specifically, the consensus network can activate the social smart contract through the social contract identification in the social addition request, and start the calling process of the social smart contract to obtain the response result of the target business node sent for the social addition request.

[0116] Furthermore, when both the social addition request and the response result are successfully consensus in the consensus network, and the response result is a rejection message for addition, the initiating business node can receive the rejection notice information generated by the target business node sent by the consensus network. The rejection notice information is used to notify the initiating business node that the addition of friends has been rejected by the target business node.

[0117] Step S206: When both the social addition request and the response result are successfully consensus in the consensus network, and the response result is an approval message for addition, obtain the target node address and the second digital certificate corresponding to the target business node from the business execution result returned by the consensus network; the first digital certificate, the second digital certificate, and the target node address are used to provide the initiating business node with the ability to communicate with the target business node.

[0118] Specifically, for the specific process of the initiating business node obtaining the target node address and the second digital certificate corresponding to the target business node, please refer to the above Figure 3The detailed description of the process in step S104 of the initiating service node for obtaining the target node address and the second digital certificate corresponding to the target service node will not be elaborated here.

[0119] Furthermore, the initiating service node can establish a first communication channel with the target service node based on the target node address. Furthermore, the initiating service node can generate a social communication request, send the social communication request based on the first communication channel, so that the target service node receives the social communication request, generates a social communication response to the social communication request, and sends the social communication response to the initiating service node through the first communication channel. Furthermore, the initiating service node can receive the social communication response sent by the target service node and generate a session window with the target service node according to the social communication response. Furthermore, the initiating service node can generate a social communication message through the session window and send the social communication message to the target service node through the first communication channel, the first digital certificate, and the second digital certificate.

[0120] Specifically, the initiating service node can obtain the second service public key corresponding to the target service node in the second digital certificate. Furthermore, the initiating service node can encrypt the obtained social communication message based on the second service public key, sign the encrypted social communication message with the target private key to obtain social signature information. Furthermore, the initiating service node can send the first digital certificate, the encrypted social communication message, and the social signature information to the target service node, so that the target service node verifies the social signature information with the certificate service public key in the first digital certificate. If the verification is successful, the target service node decrypts the encrypted social communication message with the private key corresponding to the target service node to obtain the social communication message. Correspondingly, if the verification fails, verification failure information is generated. The verification failure information is used to intercept other data sent by the target object corresponding to the verification failure information. The other data sent by the target object corresponding to the verification failure information may include other encrypted social communication messages sent by the target object corresponding to the verification failure information.

[0121] In the embodiment of the present application, by initiating a service node to obtain the first digital certificate corresponding to the target object, a perfect guarantee basis is provided for the identity authentication of the target object. In the embodiment of the present application, the security protection of the target public key is carried out during the transmission process by generating the first digital certificate, which can reduce the possibility and probability of the target public key being intercepted and cracked during the transmission process, and improve the security coefficient of the target public key during the transmission process. Further, by encapsulating the first digital certificate, the associated social identification information of the object to be added obtained, and the social contract identification into a social addition request, the social addition request contains identity authentication information, which improves the security of the social addition request. Furthermore, a secure environment is provided for the object to be added to receive the social addition request, so that a wider range of objects can be determined as the object to be added, and the range of the object to be added is improved. Further, by sending the social addition request to the consensus network, the consensus network calls the social smart contract through the social contract identification in the social addition request, and obtains the response result of the target service node for the social addition request through the social smart contract; when both the social addition request and the response result are successfully consensus in the consensus network and the response result is a message agreeing to add, obtain the target node address and the second digital certificate corresponding to the target service node from the service execution result returned by the consensus network. Among them, through the application of the social smart contract, the consensus process of the social addition request can be made procedural and regular, reducing the probability of errors in the consensus process of the social addition request. The cumbersome and redundant consensus steps can be reduced through the processes in the pre-set social smart contract, reducing the time spent on the consensus of the social addition request, improving the speed of the consensus of the social addition request, and further improving the consensus efficiency of the social addition request. Moreover, the first digital certificate, the second digital certificate, and the target node address provide the initiating service node with the ability to communicate with the target service node. By performing signature verification through the target public key in the first digital certificate, the signature information can be made more secure, strengthening the correlation between the signature information and the user of the social client corresponding to the initiating service node, making the signature information more representative of the user. That is to say, the signature information has stronger identity representative information than the prior art, improving the identity authentication effect after applying the first digital certificate. Further, after the consensus processing is successfully carried out through the consensus network in the embodiment of the present application, point-to-point communication can be performed based on the obtained second digital certificate and the target node address, avoiding the business data forwarding process of the central server. Therefore, there is no problem of excessive load on the central server, that is, the transmission pressure of the business data will be distributed to each service node in the node network where the initiating service node is located. In terms of the time spent on the transmission process of the business data, the business data queuing time will not be too long due to excessive load, improving the transmission efficiency of the social application program for transmitting business data.

[0122] Further, please refer to Figure 5 , Figure 5 which is a schematic flowchart of another data processing method provided by an embodiment of this application. As Figure 5 shown, this method can be executed by a gateway device connected to a target service node in a blockchain node system. The gateway device can be a gateway device connected to the blockchain node 10b (i.e., the target service node) shown in the above Figure 1 , which is not limited herein. For ease of understanding, an embodiment of this application takes this method being executed by the gateway device as an example for description. This data processing method can at least include the following steps S301 - step S303:

[0123] Step S301, the consensus node receives a social addition request sent by the initiating service node.

[0124] Specifically, the consensus node can detect the identity information of the first digital certificate in the social addition request to obtain the initiating identity information. Among them, if the initiating identity information corresponding to the first digital certificate exists in the legal object table of the consensus node, then continue to execute the step of obtaining the response result of the target service node for the social addition request through the social smart contract. Correspondingly, if the initiating identity information corresponding to the first digital certificate does not exist in the legal object table of the consensus node, then an authentication failure message is generated. The authentication failure message is used to instruct the initiating service node to resend the initial identity information for identity authentication to the authentication agency. Specifically, the authentication agency is used to authenticate the initial identity information.

[0125] Step S302, call the social smart contract through the social contract identifier in the social addition request, and obtain the response result of the target service node for the social addition request through the social smart contract; the social addition request is obtained by the initiating service node encapsulating the first digital certificate, the associated social identifier information corresponding to the object to be added, and the social contract identifier; the first digital certificate refers to the first digital certificate corresponding to the target object, and the target object refers to the object logging in to the social client included in the initiating service node; the target service node refers to the service node corresponding to the associated social identifier information.

[0126] Specifically, the consensus node can call the social smart contract through the social contract identifier in the social addition request, and broadcast a direct connection communication request message in the blockchain network through the social smart contract. The direct connection communication request message is used to request the establishment of a second communication channel with the target service node. Further, when the second communication channel is successfully established, the consensus node can send the social communication addition request to the target service node based on the second communication channel, and obtain the response result of the target service node for the social addition request through the second communication channel.

[0127] Step S303, when both the social addition request and the response result are successfully consensus in the consensus network and the response result is a message of agreeing to add, send the service execution result obtained at the time of successful consensus to the initiating service node, so that the initiating service node can obtain the target node address and the second digital certificate corresponding to the target service node from the service execution result; the first digital certificate, the second digital certificate and the target node address are used to provide the initiating service node with the ability to communicate with the target service node.

[0128] Further, when both the social addition request and the response result are successfully consensus in the consensus network and the response result is a message of refusing to add, the consensus node may send the rejection notice information generated by the target service node to the initiating service node. The rejection notice information is used to notify the initiating service node that the addition of friends by the target service node is refused.

[0129] The embodiment of the present application obtains the first digital certificate corresponding to the target object by initiating a business node, which provides a perfect guarantee basis for the identity authentication of the target object. Further, by encapsulating the first digital certificate, the associated social identification information of the object to be added, and the social contract identification into a social adding request, the social adding request contains the identity authentication information. By authenticating the identity authentication information, the illegal intrusion of the object without identity authentication information can be reduced, and the security of the social adding request is improved. Further, by sending the social adding request to the consensus network, so that the consensus network calls the social smart contract through the social contract identification in the social adding request, the response result of the social adding request fed back by the target business node is obtained through the social smart contract; when the social adding request and the response result are both successfully agreed in the consensus network, and the response result is the consent to add message, the target node address and the second digital certificate corresponding to the target business node are obtained from the business execution result returned by the consensus network. Among them, the social friend adding process of the object to be added is carried out through the consensus network, and the security of the consensus network is used to ensure the security of the object to be added in the social friend adding process. Furthermore, through the first digital certificate, the second digital certificate and the target node address corresponding to the target business node, point-to-point communication is directly carried out between the initiating business node and the target business node, which avoids the process of forwarding in the central server when transmitting business data. In other words, even if the central server is illegally invaded, the business data will not be leaked, ensuring the security of the business data transmission process. Moreover, the first digital certificate, the second digital certificate and the target node address provide the initiating business node with the ability to communicate with the target business node. Further, after the consensus processing is successfully carried out through the consensus network, the embodiment of the present application can perform point-to-point communication based on the obtained second digital certificate and the target node address, avoiding the business data forwarding process of the central server, so that there is no problem of excessive load on the central server, that is, the transmission pressure of the business data will be shared on each business node in the blockchain network, so that in terms of the time spent in the transmission process of the business data, the business data queuing time will not be too long due to excessive load, thereby improving the transmission efficiency of the social application to transmit business data.

[0130] For easier understanding, see Figure 6 , Figure 6 1 is a schematic diagram of a scenario for obtaining a first digital certificate in a social client provided by an embodiment of the present application. Figure 6 In a possible embodiment, when the user object corresponding to the initiating service node logs in to the social client, the social client may display the following Figure 6The forward and backward component 61K, the refresh component 62K, the login address 63S corresponding to the social client, the certificate identification control 64Z corresponding to the first digital certificate, and the service display interface 65P as shown. Among them, the forward and backward component 61K can be used to perform jumps between the current interface and the historical interfaces associated with the current interface in the social client. For example, the user of the social client can trigger the forward and backward component 61K to jump from the current interface to the previous interface among the historical interfaces associated with the current interface. Specifically, the initiating service node can sort the interfaces in the historical interfaces associated with the current interface according to time. For example, the initiating node can arrange the interfaces with earlier jump times (i.e., the times to jump to the interfaces) in the front of the historical interface queue. For example, if the jump time of interface A (i.e., the time to jump to interface A) is "11:25" and the jump time of interface B (i.e., the time to jump to interface B) is "12:05", then interface A can be arranged in the front and interface B in the back in the historical interface queue. Optionally, the initiating service node can sort the interfaces in the historical interfaces associated with the current interface according to the degree of association with the current interface. Specifically, the initiating service node can set a specific association degree algorithm and sort the interfaces in the historical interfaces associated with the current interface according to the set association degree algorithm. Among them, the specific association degree algorithm is not limited here.

[0131] Among them, the refresh component 62K can be used to refresh the current interface of the social client. Further, the login address 63S corresponding to the social client can be used to display the address of the initiating service node in the social client. Among them, the certificate identification control 64Z corresponding to the first digital certificate can be used to indicate whether the initiating service node has obtained the first digital certificate. Specifically, the initiating service node can set a specified icon for display at the position of the certificate identification control 64Z corresponding to the first digital certificate. For example, the specified icon set by the initiating service node can be an icon such as a shield, a circle, a square, or a tick, and specific limitations are not imposed here. Further, if the initiating service node obtains the first digital certificate, the set specified icon is displayed at the position of the certificate identification control 64Z corresponding to the first digital certificate. Correspondingly, if the initiating service node does not obtain the first digital certificate, a blank icon can be displayed at the position of the certificate identification control 64Z corresponding to the first digital certificate. Optionally, the initiating service node can set other styles of icons (i.e., icons different from the specified icon) for display when the initiating service node does not obtain the first digital certificate. For example, if the initiating service node obtains the first digital certificate, a shield icon is displayed at the position of the certificate identification control 64Z corresponding to the first digital certificate; then correspondingly, if the initiating service node does not obtain the first digital certificate, a flower icon is displayed at the position of the certificate identification control 64Z corresponding to the first digital certificate. Further, the service display interface 65P is used to display the specific interface of the social client. Specifically, the service display interface 65P can include an information search control 661S and a first hot search display control 671K. For example, the first hot search display control 671K can display "Today's weather". Among them, the user of the social client can trigger the first hot search display control 671K to jump to the page displayed by the first hot search display control 671K. That is to say, if a shield icon is displayed at the position of the certificate identification control 64Z corresponding to the first digital certificate, it means that the page displayed by the first hot search display control 671K is a page with a digital certificate issued by a certification authority. Based on this, the user of the social client can safely jump to the page displayed by the first hot search display control 671K by triggering the first hot search display control 671K.

[0132] For ease of understanding, please refer to Figure 7 , Figure 7 is a timing diagram of sending a social addition request provided by an embodiment of the present application. In Figure 7 , the initiating service node, the certification authority, the consensus network, and the target service node can be determined as a service transaction network for executing service transactions. For ease of understanding, an embodiment of the present application takes the process of the service transaction network executing service transactions as an example for description. The data processing method can at least include the following steps S70-step S78:

[0133] Step S70, the initiating service node sends registration information to the certification authority.

[0134] Specifically, the initiating service node can perform information extraction processing on the association information of the usage object (i.e., the target object in the embodiments of the present application) stored in the social client to obtain the registration information. For the specific description of the association information of the usage object (i.e., the target object in the embodiments of the present application) stored in the social client, please refer to the above Figure 4 specific description of the association information of the usage object in step S201, which will not be elaborated here. Specifically, the registration information may include the target social identification information of the target object. For example, the target social identification information of the target object may refer to the name "Beautiful Little Cloud" entered by the target object by triggering the information input control of the social client. Optionally, the registration information may further include information related to the social theme of the social client. For example, if the social client is a job hunting client (including application software for job hunting), the social theme may refer to the job hunting theme. At this time, the information related to the job hunting theme may refer to the job position, the number of job positions (e.g., one person holds at least two positions), the personal information of the job hunter (such as the resume of the job hunter), or what the job hunter wants to say about the job position applied for, etc., and the specific content thereof is not limited here. Further, the initiating service node can send the registration information to the certification authority.

[0135] Step S71, the initiating service node obtains the first digital certificate corresponding to the target object.

[0136] Specifically, for the specific process of the initiating service node obtaining the first digital certificate corresponding to the target object, please refer to the above Figure 3 detailed description of the process of the initiating service node obtaining the first digital certificate corresponding to the target object in step S101, which will not be elaborated here.

[0137] Step S72, the initiating service node obtains the associated social identification information corresponding to the object to be added.

[0138] Specifically, for the specific process of the initiating service node obtaining the associated social identification information corresponding to the object to be added, please refer to the above Figure 3 detailed description of the process of the initiating service node obtaining the associated social identification information corresponding to the object to be added in step S102, which will not be elaborated here.

[0139] Step S73, the initiating service node encapsulates a social addition request.

[0140] Specifically, for the specific process of the initiating service node encapsulating the social addition request, please refer to the above Figure 3The detailed description of the process in step S103 where the initiating service node encapsulates the first digital certificate, associated social identification information, and social contract identification into a social addition request will not be elaborated here.

[0141] Step S74, the initiating service node sends a social addition request to the consensus network.

[0142] Specifically, for the specific process of the initiating service node sending a social addition request to the consensus network, please refer to the above Figure 3 The detailed description of the process in step S103 where the initiating service node sends the social addition request to the consensus network will not be elaborated here.

[0143] Step S75, the consensus network invokes the social smart contract.

[0144] Specifically, for the specific process of the consensus network invoking the social smart contract, please refer to the above Figure 5 The detailed description of the process in step S302 where the consensus network invokes the social smart contract through the social contract identification in the social addition request will not be elaborated here.

[0145] Step S76, the consensus network sends the social addition request.

[0146] Specifically, the consensus network can send the social addition request to the target service node so that after the target service node receives the social addition request, it generates a response result through the social addition request. Among them, the response result can refer to the response message for the social addition request. For example, the response can be successful (i.e., agreeing to the social addition request) or failed (i.e., rejecting the social addition request).

[0147] Step S77, the target service node sends the business execution result.

[0148] Specifically, after the target service node receives the social addition request, it can generate a response result through the social addition request. In addition, the target service node can generate a business execution result through the social addition request. Among them, the business execution result can include the operation result of the operations that have been performed on the social addition request in the target service node. For example, the business execution result can refer to that the social addition request has been stored in the target service node or a storage space with a preset fixed size has been reserved in the storage space of the target service node for the target object corresponding to the social addition request. It should be understood that the business execution result can include the response result. That is to say, the business execution result not only includes the response result but also includes the operation result of the operations that have been performed on the social addition request in the target service node. Further, the target service node can send the generated business execution result to the consensus network.

[0149] Step S78, the consensus network sends the service execution result to the initiating service node.

[0150] Specifically, for the specific process of the consensus network sending the service execution result to the initiating service node, please refer to the detailed description of the process of the consensus network sending the service execution result to the initiating service node in step S303 above. Figure 5 There is no need to repeat it here.

[0151] Optionally, in the embodiment of the present application, the initiating service node may send a social addition request to a peer network (or a peer-to-peer network). The social addition request may include a first digital certificate. For the specific process of obtaining the first digital certificate, please refer to Figure 3 the detailed process of the initiating service node obtaining the digital certificate in step S101 above and Figure 4 the detailed process of the initiating service node obtaining the digital certificate in steps S201 - S203 above. There is no need to repeat it here. Further, after receiving the social addition request sent by the initiating service node, the peer network may send the social addition request to the target service node through the business smart contract configured in the peer network, so that the target service node generates a service execution result and sends the generated service execution result to the peer network. Further, the initiating service node may receive the service execution result generated by the target service node sent by the peer network, and obtain the target node address and the second digital certificate corresponding to the target service node from the service execution result.

[0152] The embodiment of the present application obtains the first digital certificate corresponding to the target object by initiating a business node, which provides a perfect guarantee basis for the identity authentication of the target object. Further, by encapsulating the first digital certificate, the associated social identification information of the object to be added, and the social contract identification into a social adding request, the social adding request contains the identity authentication information. By authenticating the identity authentication information, the illegal intrusion of the object without identity authentication information can be reduced, and the security of the social adding request is improved. Further, by sending the social adding request to the consensus network, so that the consensus network calls the social smart contract through the social contract identification in the social adding request, the response result of the social adding request fed back by the target business node is obtained through the social smart contract; when the social adding request and the response result are both successfully agreed in the consensus network, and the response result is the consent to add message, the target node address and the second digital certificate corresponding to the target business node are obtained from the business execution result returned by the consensus network. Among them, the social friend adding process of the object to be added is carried out through the consensus network, and the security of the consensus network is used to ensure the security of the object to be added in the social friend adding process. Furthermore, through the first digital certificate, the second digital certificate and the target node address corresponding to the target business node, point-to-point communication is directly carried out between the initiating business node and the target business node, which avoids the process of forwarding in the central server when transmitting business data. In other words, even if the central server is illegally invaded, the business data will not be leaked, ensuring the security of the business data transmission process. Moreover, the first digital certificate, the second digital certificate and the target node address provide the initiating business node with the ability to communicate with the target business node. Further, after the consensus processing is successfully carried out through the consensus network, the embodiment of the present application can perform point-to-point communication based on the obtained second digital certificate and the target node address, avoiding the business data forwarding process of the central server, so that there is no problem of excessive load on the central server, that is, the transmission pressure of the business data will be shared on each business node in the blockchain network, so that in terms of the time spent in the transmission process of the business data, the business data queuing time will not be too long due to excessive load, thereby improving the transmission efficiency of the social application to transmit business data.
