[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] See also Figure 1 , Figure 1 This is a network architecture diagram of the application control method provided in the embodiment of the present application. Blockchain is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. Blockchain is essentially a decentralized database, a string of data blocks generated by cryptographic methods. Decentralized applications run based on smart contracts stored in decentralized databases. Figure 1 , decentralized application 20 and decentralized application 30 run on blockchain 40. Decentralized application 20 obtains instruction information of target user 10, the instruction information carries a first application identifier and a user identifier of target user 10, the first application identifier is used to mark decentralized application 30, and the instruction information is used to control decentralized application 30 to perform the target operation function.

[0056] See also Figure 2 , Figure 2 It is a timing diagram of the application control method provided in an embodiment of the present application. Figure 2 The application control method shown may include the following steps S201 to S207.

[0057] S201: Obtain instruction information of a target user.

[0058] In some feasible implementations, when the target user accesses or uses a decentralized application (hereinafter referred to as the first decentralized application for convenience of description), the first decentralized application can monitor the user's operation information in real time. When the target user is monitored for controlling another decentralized application (hereinafter referred to as the second decentralized application for convenience of description) to perform the target operation function, the first decentralized application can obtain the target user's instruction information and then control the second decentralized application to perform the target operation function according to the target user's instruction information. Among them, the above-mentioned instruction information can be gesture information, voice information, and text information, etc., which can be determined according to the actual application scenario, and is not limited here. Among them, the above-mentioned instruction information can be any information that controls the second decentralized application to perform the corresponding target operation function, which can be determined according to the application type and actual application scenario of the second decentralized application, and is not limited here. For example, when the second decentralized application is an access control application installed on the unit door, the above-mentioned instruction information can be used to control the access control application to perform door opening operation functions, door locking functions, etc. For another example, when the second decentralized application is an application installed on a sweeping robot, the above-mentioned instruction information can be used to control the second decentralized application to perform sweeping operation functions, etc. It should be particularly noted that the above-mentioned first decentralized application and the second decentralized application are applications with control functions or information transmission, such as remote control applications, etc., which can also be determined according to the actual application scenario and are not limited here. Among them, the instruction information of the above-mentioned target user may carry an application identifier for marking the second decentralized application (hereinafter referred to as the first application identifier for the convenience of description) and the user identifier of the above-mentioned target user, so that the first decentralized application can determine whether to control the second decentralized application to perform the target function according to the user identifier of the target user and the first application identifier of the second decentralized application.

[0059] S202: Generate a control instruction according to the instruction information and the second application identifier of the first decentralized application.

[0060] In some feasible implementations, after obtaining the instruction information of the target user, the first decentralized application may generate a control instruction based on the instruction information of the target user and the application identifier of the first decentralized application (hereinafter referred to as the second application identifier for the convenience of description) to control the second decentralized application to perform the target operation function corresponding to the above instruction information. Specifically, in order to improve the information security of the above instruction information, the first decentralized application may encrypt the instruction information according to the private key of the first decentralized application (hereinafter referred to as the first private key for the convenience of description) to obtain the encrypted instruction information corresponding to the above instruction information. On the other hand, in order to enable the second decentralized application to recognize that the control instruction comes from the above-mentioned first decentralized application, the first decentralized application may use the second application identifier of the first decentralized application to mark the encrypted information instruction to obtain the control instruction corresponding to the instruction confidence. Optionally, the first decentralized application may also use the preset encryption algorithm of the first decentralized application to encrypt the information instruction, and use the second application identifier to mark the encrypted instruction information to obtain the control instruction corresponding to the instruction information. The preset encryption algorithms include but are not limited to the Data Encryption Standard (DES), the Triple Data Encryption Algorithm (TDEA), and the RSA encryption algorithm, etc., which can be determined based on the actual application scenario and are not limited here. The first application identifier and the second application identifier are only used to mark and distinguish the first decentralized application and the second decentralized application, and can be one or more combinations of numbers, symbols, and strings, which can be determined based on the actual application scenario and are not limited here.

[0061] S203: Execute the first smart contract to obtain authorization data of the target user from the user authorization database of the second decentralized application in the blockchain.

[0062] In some feasible implementations, since the second decentralized application and the first decentralized application are different applications, when the target user uses the first decentralized application, the first decentralized application cannot determine whether the target user can control the second decentralized application to perform the target operation function, that is, the first decentralized application needs to determine whether the target user has the authority to control the target user. Specifically, the first decentralized application can execute the smart contract preset when generating the control instruction (for the convenience of description, hereinafter referred to as the first smart contract) to determine the user authorization database of the second decentralized application from the blockchain. Among them, the authorization data of each user in the user authorization database of the above-mentioned target user is used to illustrate that the corresponding user has the authority to control the second decentralized application. Among them, the authorization data of each user is the authorization data generated by the second decentralized application according to the user information of the user when the user uses the second decentralized application for the first time, and can also be the authorization data set by the second decentralized application for users within a preset range. It can be determined according to the actual application scenario and is not limited here. The first decentralized application can determine the target block storing the first application identifier from the blockchain by executing the first smart contract, or determine the target block marked by the first application identifier from the blockchain, and further obtain the user authorization database of the second decentralized application from the target block. Furthermore, the first decentralized application can obtain the authorization data of the target user from the user authorization database of the second decentralized application according to the user identifier of the target user to determine whether the target user has the authority to control the second decentralized application.

[0063] S204. When the authorization data of the target user is obtained, a second smart contract associated with the second decentralized application is obtained from the blockchain, and the second smart contract is executed to send a control instruction to the second decentralized application through the blockchain, so that the second decentralized application performs the target operation function.

[0064] In some feasible implementations, when the authorization data of the target user is successfully obtained from the user authorization database of the second decentralized application, the first decentralized application can determine that the target user has the authority to control the second decentralized application. Since the first decentralized application and the second decentralized application are based on smart contracts and run on the blockchain, the first decentralized application can determine the smart contract associated with the second decentralized application from the blockchain (for the convenience of description, hereinafter referred to as the second smart contract), and then execute the second smart contract so that the blockchain sends the control instruction to the second decentralized application. Among them, the above-mentioned second smart contract is a smart contract preset by the second decentralized application for being executed by the first decentralized application to trigger the second decentralized application to receive the control instruction sent by the first decentralized application. The specific setting method can be determined based on the actual application scenario and is not limited here.

[0065] Optionally, in some feasible implementations, in order to prevent the control instruction from being tampered with during the transmission process from the first decentralized application to the second decentralized application, and thus ensure that the second decentralized application performs the correct target operation function, the first decentralized application performs a hash calculation on the instruction information to obtain the first summary information of the instruction information. On the other hand, in order to achieve the purpose of preventing the control instruction from being tampered with, the second decentralized application can determine that the control instruction corresponding to the instruction information comes from the second decentralized application, and the first decentralized application can send a key acquisition request to the second decentralized application to obtain the private key of the target user (hereinafter referred to as the second private key for convenience of description). Thus, the first decentralized application can encrypt the above-mentioned first summary information according to the second private key of the target user to obtain the digital signature of the instruction information. Based on the above implementation, the first decentralized application can send the control instruction and the digital signature to the blockchain together, and after executing the above-mentioned second smart contract at the same time so that the blockchain receives the above-mentioned controllable instruction and the digital signature, the control instruction and the digital signature are sent to the second decentralized application, so that the second decentralized application can determine whether the above-mentioned control instruction has been tampered with according to the above-mentioned digital signature.

[0066] Optionally, in some feasible implementations, before generating a control instruction based on the instruction information and the second application identifier of the first decentralized application, the decentralized application may pre-determine whether the instruction information of the target user is in an executable state, that is, whether the target operation function corresponding to the above instruction information can be executed by the second decentralized application. Specifically, the first decentralized application can obtain the instruction state parameter of the instruction information, and send the instruction state parameter to the consensus node in the blockchain so that the consensus node determines whether the instruction information is in an executable state according to the above instruction state parameter. Among them, when each formula node determines that the above instruction state parameter is in an executable state, it can send a signature confirmation message to the first decentralized application. After receiving the signature confirmation message sent by each consensus node, the first decentralized application determines that the above instruction information is in an executable state when the data of the signature confirmation message is greater than the preset ratio of the number of all consensus nodes in the blockchain (such as half, two-thirds, etc., which can be determined according to the actual application scenario and is not limited here). , That is, the above target operation function can be executed by the second decentralized application. Alternatively, the first decentralized application may determine whether there is a signature confirmation message from a preset consensus node in the signature confirmation message it receives. When there is a signature confirmation message from a preset consensus node, the first decentralized application may determine that the above instruction information is in an executable state. The above instruction state parameter may be an instruction field corresponding to the target operation function. For example, for the access control application, 0001 represents the door closing function and 0010 represents the door opening function. Therefore, for each consensus node, when the above instruction state parameter is 0001, the consensus node may obtain the function parameter of the second decentralized application from the blockchain and determine whether there is a state parameter of 0001 in the function parameter. When there is, the consensus node may determine that the above instruction state parameter is in an executable state. Alternatively, the above instruction state parameter may also be the instruction format of the target operation function, and the preset instruction format of the second decentralized application is obtained from the blockchain. When the above instruction format is the preset instruction format of the second decentralized application, each consensus node may determine that the above instruction information is in an executable state. Based on the above implementation, when the above instruction information is in an executable state, the first decentralized application can further generate a control instruction according to the instruction information and the second application identifier of the first decentralized application. It should be noted that the specific implementation method of each consensus node determining whether the instruction information is in an executable state according to the instruction state parameter can be determined according to the actual application scenario and is not limited here.

[0067] In some feasible implementations, when the authorization data of the target user is not successfully obtained from the user authorization database of the second decentralized application, the first decentralized application can directly establish a communication connection with the second decentralized application, and send the control instruction to the second decentralized application through the communication connection, so that the second decentralized application can perform the target operation function according to the control instruction. Specifically, the first decentralized application can send a communication request to the second decentralized application, and after receiving the communication request, if the second decentralized application agrees to establish a communication connection with the first decentralized application, it can send a synchronization sequence number and a first confirmation character to the first decentralized application. Among them, the above-mentioned synchronization sequence number is used to indicate to the first decentralized application that the second decentralized application agrees to establish a communication connection with it, and the above-mentioned first confirmation character user indicates that the second decentralized application confirms the received communication request correctly. Further, after receiving the synchronization sequence number and the first confirmation character, the first decentralized application can send a second confirmation character to the second decentralized application to notify the second decentralized application that the first decentralized application confirms the synchronization sequence number and the second confirmation character sent by it, thereby establishing a communication connection with the second decentralized application. Based on the communication connection between the second decentralized application and the first decentralized application, the first decentralized application can send a control instruction to the second decentralized application through the communication connection to enable the second decentralized application to perform a target operation function.

[0068] See also Figure 3 , Figure 3 Schematic diagram of a scenario for establishing a communication connection provided by an embodiment of the present application. Figure 3 In , SYN represents the synchronization sequence number, ACK represents the confirmation character, and Seq represents the sequence number. When the first decentralized application sends a data packet with a synchronization sequence number of 1 and a randomly generated Seq of X (such as 1234567) to the second decentralized application. Among them, the second decentralized application can know that the first decentralized application requests to establish a communication connection from the synchronization sequence number of 1. Further, after receiving the request, the second decentralized application needs to confirm the establishment of a communication connection. The second decentralized application can send a data packet with a sequence number of Y (Y=X+1) and a confirmation character of 1 to the first decentralized application. Finally, after receiving the data packet sent by the second decentralized application, the first decentralized application can check whether the confirmation character sent by the second decentralized application is 1 and whether the sequence number is X+1. If correct, the first decentralized application sends a data packet with a confirmation character of 1 and a sequence number of Y (Y=X+1) to the second decentralized application, so that the first decentralized application establishes a communication connection with the second decentralized application.

[0069] S205: Receive a control instruction, and determine a second application identifier of the first decentralized application according to the control instruction.

[0070] In some feasible implementations, since the second decentralized application itself is an application with a specific type and specific functions, after receiving the control instruction sent by the blockchain, the second decentralized application can obtain the second application identifier that marks the control instruction, and determine the first decentralized application based on the second application identifier to determine that the above control instruction comes from the first decentralized application. At this time, the second decentralized application can determine whether to execute the control instruction from the first decentralized application, that is, when the second decentralized application has a control relationship with the first decentralized application, the second decentralized application can execute the control instruction from the first decentralized application. Among them, the control relationship between the second decentralized application and other decentralized applications can be stored in the blockchain by the second decentralized application, so that the second decentralized application can search the control relationship between the second decentralized application and the first decentralized application from the blockchain at any time. Among them, the above control relationship is used to illustrate that the first decentralized application has the authority to control the second decentralized application to perform the corresponding operation function.

[0071] S206. Send the first application identifier and the second application identifier of the second decentralized application to a consensus node in the blockchain, so that the consensus node determines whether the second decentralized application and the first decentralized application have a control relationship.

[0072] In some feasible implementations, the second decentralized application may send the first application identifier of the second decentralized application and the second application identifier of the first decentralized application to the consensus node in the blockchain, so that each consensus node determines whether the second decentralized application and the first decentralized application have a control relationship. Specifically, each consensus node can parse all smart contracts in the blockchain, and when there is a contract code of a certain smart contract that has an associated field associated with the first application identifier and the second application identifier, it can be determined that the second decentralized application and the first decentralized application have a control relationship. Alternatively, each consensus node can obtain the application data of the first decentralized application from the blockchain according to the second application identifier, or obtain the application data of the second decentralized application from the blockchain according to the first application identifier. When there is an instruction association record with the second decentralized application in the application data of the first decentralized application, or there is an instruction association record with the first decentralized application in the application data of the second decentralized application, each consensus node can determine that the second decentralized application and the first decentralized application have a control relationship. Alternatively, each consensus node may obtain a list of associated applications of the second decentralized application from the blockchain according to the first application identifier, or obtain a list of associated applications of the first decentralized application from the blockchain according to the second application identifier. When the list of associated applications of the second decentralized application includes the first decentralized application, or when the list of associated applications of the first decentralized application includes the second decentralized application, each consensus node may determine that the first decentralized application and the second decentralized application have a control relationship. After determining that the first decentralized application and the second decentralized application have a control relationship, each consensus node may send a signature confirmation message to the second decentralized application so that the second decentralized application confirms whether the first decentralized application and the second decentralized application have a control relationship according to the received signature confirmation message. The specific implementation method of the second decentralized application determining whether the first decentralized application and the second decentralized application have a control relationship according to the signature confirmation message can be referred to the implementation method shown in step S204, which will not be repeated here.

[0073] S207: When the second decentralized application has a control relationship with the first decentralized application, determine instruction information according to the control instruction, and execute a target operation function corresponding to the instruction information.

[0074] In some feasible implementations, when the second decentralized application and the first decentralized application have a control relationship, the second decentralized application may use a decryption method corresponding to a preset encryption method to decrypt the encrypted instruction information corresponding to the control instruction to obtain instruction information. The control instruction is obtained by the first decentralized application encrypting the instruction information according to the first private key of the first decentralized application, and marking the encrypted instruction information with the second application identifier of the first decentralized application. The first decentralized application may use the public key of the first decentralized application (hereinafter referred to as the second public key for convenience of description) to decrypt the encrypted instruction information using a preset decryption method to obtain the instruction information. The decryption algorithm corresponding to the preset decryption method corresponds to the encryption algorithm used by the first decentralized application, which can be determined according to the actual application scenario and is not limited here.

[0075] In some feasible implementations, when the control instruction received by the second decentralized application also carries a digital signature, the second decentralized application can digitally sign and verify whether the control instruction has been tampered with before receiving the control instruction. Specifically, the second decentralized application can execute a smart contract for obtaining a decryption key (hereinafter referred to as the third smart contract for convenience of description) so that the blockchain triggers the first decentralized application to obtain the public key of the target user (hereinafter referred to as the first public key for convenience of description) under the contract rules of the third smart contract, and sends the first public key to the second decentralized application through the blockchain again. Alternatively, when there is a communication connection between the second decentralized application and the first decentralized application, the second decentralized application can directly send a public key acquisition request to the first decentralized application so that the first decentralized application obtains the first public key of the target user. Furthermore, the first decentralized application performs a hash calculation on the instruction information to obtain the first summary information of the instruction information, and decrypts the digital signature according to the first public key to obtain the second summary information of the instruction information. On the other hand, the second decentralized application can compare the first summary information with the second summary information. When the first summary information and the second summary information are consistent, it means that the instruction information or the control instruction has not been tampered with before the second decentralized application receives the control instruction from the blockchain. At this time, the second decentralized application can execute the target operation function corresponding to the instruction information, such as the access control application executing door opening, the sweeping robot application executing sweeping, etc. The specific operation can be determined according to the actual instruction information and is not limited here. Figure 4 , Figure 4 Schematic diagram of the scene of verification instruction information provided by the embodiment of the present application. Figure 4In the example, it is assumed that the digital signature of the instruction information is 1111111, and after decrypting the digital signature 1111111 using the first public key of the target user, the second summary information 1000100 is obtained.
