Technical Field

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

[0002] In recent years, various social applications have emerged one after another, and online social networking has gradually become an indispensable way of socializing in people's lives.

[0003] Currently, most social applications are server-side based, requiring each client to establish a connection with the server to function properly, as data such as social media accounts are stored on the server. Therefore, it's understandable that server-side social applications are centralized; all data and information are stored on the server, making them vulnerable to attack, which could easily lead to the loss of sensitive data. Summary of the Invention

[0088] The object instant conversation module is also used to send instant conversation messages to the object terminal device via object peer-to-peer connection.

[0089] One embodiment of this application provides a computer device, including: a processor, a memory, and a network interface;

[0090] The processor is connected to the memory and the network interface. The network interface is used to provide a data communication network element, the memory is used to store a computer program, and the processor is used to call the computer program to execute the method in the embodiments of this application.

[0091] One aspect of this application provides a computer-readable storage medium storing a computer program adapted for loading by a processor and executing the methods described in this application.

[0092] One aspect of this application provides a computer program product or computer program that includes computer instructions stored in a computer-readable storage medium. A processor of a computer device reads the computer instructions from the computer-readable storage medium and executes the computer instructions, causing the computer device to perform the method described in this application.

[0093] In this embodiment, when responding to a first object's account registration request for a social application, a private key is generated for the first object based on blockchain rules. Further, a public key and an account address corresponding to the first object are generated based on the private key. The blockchain rules are stored in the terminal device corresponding to the first object. Then, an account registration transaction for the first object is sent to the blockchain network based on the private key, public key, and account address. The blockchain network packages the account registration transaction into the target block and performs consensus on the target block. If a registration success notification is received from the backend server corresponding to the social application, the account address is identified as a social account. This private key, public key, and social account are used to provide the first object with the ability to perform social interactions within the social application. The registration success notification is generated by the backend server when it reaches the target block and successfully completes consensus on the blockchain. Using the method provided in this application embodiment, the object's account information will be stored in the blockchain. Even if the backend server is attacked, the object's account information will not be lost, thus realizing the decentralization of the object's social account. In addition, the data generated by the object through social interaction through social applications needs to be uploaded to the blockchain using public and private keys. Because public and private keys can only be generated and stored on terminal devices that have integrated and installed the application client, they are not easy to be leaked, reducing the possibility that the data of social applications will be tampered with before being uploaded to the blockchain, thereby improving the data security of social applications.

[0108] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0109] Blockchain is a novel application model of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanisms, and encryption algorithms. It is primarily used to organize data chronologically and encrypt it into a ledger, making it tamper-proof and forgery-proof. It also allows for data verification, storage, and updating. Essentially, a blockchain is a decentralized database where each node stores an identical copy. The blockchain network can distinguish between consensus nodes and business nodes, with the consensus node responsible for achieving consensus across the entire network. The process of writing transaction data into the ledger in a blockchain network can be summarized as follows: a client sends transaction data to a business node, which then relays this data among the business nodes in the blockchain network until the consensus node receives it. The consensus node then packages the transaction data into a block and reaches a consensus with other consensus nodes. Once consensus is reached, the block containing the transaction data is written into the ledger.

[0110] In this context, it can be understood that a block is a data packet that carries transaction data (i.e., transaction business) on a blockchain network. It is a data structure that is marked with a timestamp and the hash value of the previous block. The transactions in the block are verified and confirmed by the network's consensus mechanism.

[0111] In this context, a hash value, also known as an information feature value or characteristic value, is generated by converting input data of arbitrary length into cryptographic data and producing a fixed output using a hash algorithm. The original input data cannot be retrieved by decrypting the hash value; it is a one-way cryptographic function. In a blockchain, each block (except the initial block) contains the hash value of its predecessor block, which is called the parent block of the current block. The hash value is a core and crucial aspect of blockchain technology, preserving the authenticity of recorded and viewed data, as well as the integrity of the blockchain as a whole.

[0112] It is understood that a blockchain system can include smart contracts. A smart contract can be understood and executed by all nodes in the blockchain (including consensus nodes), capable of executing arbitrary logic and producing results. Users can initiate a transaction request through a client, invoking a smart contract already deployed on the blockchain. Subsequently, the transaction nodes on the blockchain can send the request to the consensus nodes, which can then run the smart contract. It should be understood that a blockchain can include one or more smart contracts, distinguished by an identity document (ID) or name. The client's transaction request can also carry the smart contract's identity document or name, specifying the smart contract the blockchain needs to run. If the smart contract specified by the client requires data retrieval, each consensus node will access its local ledger to read the data. Finally, the consensus nodes will verify the consistency of the execution results (i.e., reach consensus). If they are consistent, the execution result can be stored in their respective local ledgers and returned to the client.

[0113] The method provided in this application requires blockchain implementation. Because social applications have high requirements for information iteration and updates, public blockchains are generally unsuitable. Therefore, this application requires selecting a blockchain engine that offers fast block generation and stability. The block engine is a low-level component that encapsulates logic code, enabling rapid blockchain deployment. Please refer to [link to previous section]. Figure 1 , Figure 1 This is a schematic diagram illustrating a blockchain construction process provided in an embodiment of this application. Figure 1 As shown, the setup process mainly includes the following steps:

[0114] Step S001: Select the blockchain engine.

[0115] Step S002: Download and compile the blockchain engine code.

[0116] Step S003: Modify the configuration file according to the blockchain network information to be built. For example: the IP addresses (Internet Protocol) and ports of all nodes required by the network module; the consensus module needs to be configured to use which consensus algorithm, etc.

[0117] Specifically, when configuring the consensus module, if you prefer eventual consistency and performance, you can choose the Raft consensus algorithm; if you prefer Byzantine fault tolerance for malicious nodes, you can choose the BFT (Byzantine Fault Tolerance) consensus algorithm.

[0118] Step S004: Upload the compiled code and configuration files to the corresponding blockchain node.

[0119] Step S005: Execute the blockchain engine startup command to start the blockchain.

[0120] Step S006, Network Initialization.

[0121] Step S007, consensus initialization.

[0122] Step S008: Complete the blockchain startup.

[0123] Specifically, the blockchain engine initializes each module in the order of dependency; for example, the consensus module depends on the initialization of the network module.

[0124] Specifically, following the steps above, assuming the Raft consensus algorithm is chosen, you can first download the engine code, compile it, and deploy it on 5 (2n+1) servers. After deploying the consensus algorithm, start the blockchain. Because Raft-like consensus algorithms require a majority vote for consensus, it's best to have an odd number of nodes. This is beneficial for consensus and also facilitates later log viewing and analysis.

[0125] Please see again. Figure 2 , Figure 2 This is a schematic diagram of a network architecture provided in an embodiment of this application. For example... Figure 2 As shown, the network architecture may include a blockchain node cluster 1000, a backend server (server-side) cluster 100, and a terminal device (client-side) cluster 10. The blockchain node cluster 1000 may include at least two blockchain nodes. Figure 1 As shown, the blockchain node cluster 1000 may include blockchain node 1000a, blockchain node 1000b, ..., blockchain node 1000n; the backend server cluster 100 may specifically include backend server 100a, backend server 100b, ..., backend server 100n; and the terminal device cluster 10 may specifically include terminal device 10a, terminal device 10b, ..., terminal device 10n. The setup process for the blockchain node cluster 1000 can be referred to the above. Figure 1 The setup process shown will not be described in detail here.

[0126] like Figure 2As shown, terminal devices 10a, 10b, ..., 10n can respectively connect to backend servers 100a, 100b, ..., 100n to facilitate data interaction between the terminal devices and the backend servers; terminal devices 10a, 10b, ..., 10n can respectively connect to blockchain nodes 1000a, 1000b, ..., 1000n to facilitate data interaction between the terminal devices and the blockchain nodes; backend servers 100a, 100b, ..., 100n can respectively connect to blockchain nodes 1000a, 1000b, ..., 1000n to facilitate data interaction between the backend servers and the blockchain nodes; blockchain nodes 1000a, 1000b, ..., 1000n are interconnected to facilitate data interaction between the blockchain nodes.

[0127] It is understandable that blockchain nodes can transmit data or blocks through the aforementioned data connections. The blockchain network can establish data connections between blockchain nodes based on node identifiers. Each blockchain node in the network has a corresponding node identifier, and each blockchain node can store the node identifiers of other blockchain nodes that are connected to it. This allows it to broadcast acquired data or generated blocks to other blockchain nodes based on their node identifiers. For example, blockchain node 1000a can maintain a node identifier list as shown in Table 1, which stores the node names and node identifiers of other nodes.

[0128] Table 1

[0129] Blockchain node 1000a AAA.AAA.AAA.AAA Blockchain node 1000b BBB.BBB.BBB.BBB … … 1000n blockchain nodes CCC.CCC.CCC.CCC

[0130] The node identifier can be an Internet Protocol (IP) address or any other information that can be used to identify a blockchain node in a blockchain network. Table 1 only uses IP addresses as an example. For instance, blockchain node 1000a can send information (e.g., transaction data) to blockchain node 1000b using the node identifier BBB.BBB.BBB.BBB, and blockchain node 1000b can determine that the information was sent by blockchain node 1000a using the node identifier AAA.AAA.AAA.AAA.

[0131] In blockchain, before a block can be added to the chain, it must pass consensus among the consensus nodes in the blockchain network. Only after consensus is reached can the block be added to the blockchain. Understandably, when blockchain is used in some scenarios by commercial organizations, not all participating nodes in the blockchain (i.e., the blockchain nodes in the aforementioned blockchain node cluster of 1000) have sufficient resources and the necessity to become consensus nodes. For example, in... Figure 2 In the blockchain node cluster 1000 shown, blockchain nodes 1000a, 1000b, and 1000n can be used as consensus nodes. Consensus nodes in blockchain node cluster 1000 participate in consensus, that is, reaching consensus on blocks (containing a batch of transactions), including generating blocks and voting on blocks; while non-consensus nodes do not participate in consensus, but help propagate block and voting messages, and synchronize states with each other.

[0132] It is understood that the above-mentioned data connection is not limited to the connection method. It can be connected directly or indirectly through wired communication, or directly or indirectly through wireless communication, or through other connection methods. This application does not impose any restrictions on this.

[0133] It is understood that the blockchain-based data processing method provided in this application embodiment can be executed by a computer device, which includes, but is not limited to, the aforementioned blockchain node (which can be a terminal or a server), a backend server, and a terminal device. The aforementioned server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The aforementioned terminal device can be a smartphone, tablet computer, laptop computer, desktop computer, smart speaker, smartwatch, etc., but is not limited to these.

[0134] It is understood that the embodiments of this application can be applied to various scenarios, including but not limited to cloud technology, artificial intelligence, smart transportation, and assisted driving.

[0135] It is understood that, in the specific implementation of this application, the data related to account registration transactions, social interaction on-chain transactions, etc., when applied to specific products or technologies, requires user permission or consent, and the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0136] like Figure 2As shown, each terminal device in the terminal device cluster can have an application client installed. When the application client runs on each terminal device, it can interact with any of the backend servers in the aforementioned backend server cluster 100, enabling any of the backend servers in the cluster to receive business data from each terminal device. This application client can be a client for social applications with the ability to display text, images, audio, and video data, such as game applications, video editing applications, instant messaging applications, live streaming applications, short video applications, video applications, music applications, shopping applications, novel applications, payment applications, or browsers. This application client can be a standalone client or an embedded sub-client integrated into another client (such as an instant messaging client, social client, video client, etc.), and is not limited here.

[0137] The terminal device bound to the first object can perform social interaction operations through the application client of a social application. To achieve decentralization of online social interaction for the object, it is necessary to first ensure the decentralization of the social account system used by the object. Therefore, this application embodiment provides a data processing method based on blockchain, such as... Figure 2 As shown, the terminal device bound to the first object can respond to the first object's account registration request for the social application by running the application client. It generates a private key for the first object based on blockchain rules, which are stored on the terminal device corresponding to the first object. Then, it generates a public key and an account address corresponding to the first object based on the private key. Next, it sends an account registration transaction for the first object to the blockchain network based on the private key, public key, and account address. This allows the blockchain network to package the account registration transaction into the target block and perform consensus on the target block. If a registration success message is received from the backend server corresponding to the social application, the account address is identified as a social account. Subsequently, the private key, public key, and social account will be used to provide the first object with the ability to perform social interactions within the social application. This registration success message is generated by the backend server when it reaches the target block and successfully completes consensus on the blockchain. In short, the social media account information of the first party is stored in the blockchain. Therefore, even if the social media account information of the first party is changed in the backend server due to a malicious attack, it can still be verified in the blockchain, ensuring the decentralization of the social media account system used by the party. Subsequently, data related to social interactions performed by terminal devices through the application client of social applications can also be recorded on the blockchain based on private keys, public keys and social media accounts, thereby realizing the decentralization of online social interaction.

[0138] To facilitate understanding of the above process, please refer to the following: Figures 3a-3b Among them, such as Figures 3a-3bThe terminal device 20 shown can be the one described above. Figure 2 Any terminal device in the terminal device cluster 10 shown, such as terminal device 20, can be terminal device 10a; Figures 3a-3b The backend server 200 shown can be the one described above. Figure 2 Any of the backend servers in the backend server cluster 100 shown, such as backend server 200, could be backend server 200b; for example... Figures 3a-3b The blockchain network 2000 shown can be the above Figure 2 The blockchain network shown is composed of 1000 blockchain node clusters. Blockchain node 2001 in blockchain network 2000 can be one of the aforementioned... Figure 2 Any blockchain node in the blockchain node cluster 1000 shown, such as blockchain node 2001, is blockchain node 1000a.

[0139] Please refer to [the website / information] first. Figure 3a , Figure 3a This is a schematic diagram illustrating a scenario of decentralized social media account registration request being uploaded to the blockchain, as provided in an embodiment of this application. Assuming that terminal device 20 is bound to object A, and terminal device 20 has the application client of social application 21 installed, if object A does not yet have a social media account to log in to the social application, object A can first register an account through the application client of social application 21. Figure 3a As shown, the account registration interface of social application 21 displays a regular registration option 211 and an on-chain registration option 212. Object A can trigger regular registration option 211 to register for social application 21, that is, directly apply for account registration for social application 21 from the backend server 200 corresponding to social application 21. Object A can also trigger on-chain registration option 212 to register for social application 21, that is, complete the registration for social application 21 through the blockchain network 2000. Assuming object A triggers on-chain registration option 212, terminal device 20 can respond to object A's triggering operation of on-chain registration option 212 by generating an account registration request for social application 21. Subsequently, as... Figure 3aAs shown, terminal device 20 can respond to the account registration request, then generate a private key B for object A based on blockchain rules, and then generate a public key C and account address D corresponding to object A based on private key B. The blockchain rules can be pre-set private key generation rules, which may include private key length, types of characters that can be used in the private key, random rules, etc. At this point, object A's account registration is not successful. Terminal device 20 also needs to generate an account registration transaction 22 based on private key B, public key C, and account address D. This account registration transaction 22 is used to store object A's relevant identity information for registering with social application 21 on the blockchain. Terminal device 20 will send this account registration transaction 22 to any blockchain node in the blockchain network 2000, such as blockchain node 2001, and then wait for the blockchain network to process the account registration transaction 22.

[0140] like Figure 3a As shown, in the blockchain network 2000, the account registration transaction 22 can be packaged into the target block 23. Then, the blockchain network 2000 will perform consensus processing on the target block 23. If the blockchain network 2000 passes the consensus on the target block 23, the target block 23 will be added to the blockchain for storage.

[0141] Please see also Figure 3b , Figure 3b This is a schematic diagram illustrating a scenario of successful decentralized social media account registration provided in an embodiment of this application. For example... Figure 3b As shown, the backend server 200 corresponding to the social application 21 traverses blockchain 24 in the blockchain network 2000. The backend server 200 can traverse blockchain 24 at a fixed frequency, or when a new block is added to blockchain 24, any blockchain node in the blockchain network 2000 sends a notification to the backend server 200, and then the backend server 200 traverses blockchain 24 once. Alternatively, it can traverse blockchain 24 at other frequencies; this application does not impose any restrictions. When the backend server 200 first traverses blockchain 24 and reaches the account registration transaction 22 in the target block 23, the backend server 200 can generate a registration success message 25 to indicate that the social account of object A has been successfully registered, and then send it to the terminal device 20. Upon receiving the registration success message 25 from the backend server 200, the terminal device 20 can identify the account address D as the social account of object A and save the private key B and public key C. When object A uses social application 21 through terminal device 20, private key B, public key C, and social account can provide object A with the ability to perform social interactions in the social application.

[0142] As described above, when the first user registers an account on a social application, they no longer directly apply to the application's backend server or store the information there. Instead, they first generate a private key, public key, and account address associated with them. Then, through the account registration transaction, this information is stored on the blockchain, thus achieving decentralization of the social account system. Because blockchain technology has the characteristic of immutable data, even if the backend server is maliciously attacked, the first user's correct identity information can still be verified, greatly improving the security of their online social interactions. Furthermore, the public and private keys associated with the first user are generated and stored based on the terminal devices associated with them, without needing to go through a backend server. The public and private keys of different users are generated and stored based on the terminal devices bound to different users, ensuring their security and reducing the possibility of leakage.

[0143] Further, please see Figure 4 , Figure 4 This is a flowchart illustrating a blockchain-based data processing method provided in an embodiment of this application. The method can be implemented by a terminal device (e.g., the one described above). Figure 2 The method is executed by any terminal device in the terminal device cluster 10 of the corresponding embodiment. The following description will use the execution of this method by a terminal device as an example. The blockchain-based data processing method may include at least the following steps S101-S104:

[0144] Step S101: In response to the first object's account registration request for the social application, a private key is generated for the first object based on blockchain rules; the blockchain rules are stored in the terminal device corresponding to the first object.

[0145] Specifically, the first user needs a social media account corresponding to the social media application to have the permission to log in or use the application normally. Therefore, when the first user uses the social media application for the first time, they need to register a social media account for the application through the client software installed on their device. The device can then respond to the user's account registration request and generate a private key for the user based on blockchain rules. These blockchain rules may include private key generation rules, such as the length of the private key, the types of characters that can be included, the rules for random characters, and uniqueness verification rules.

[0146] Specifically, the terminal device can integrate and install a blockchain-related SDK (Software Development Kit). The generation of the aforementioned private key can also be achieved through the SDK, meaning that blockchain rules can be stored in the SDK. Furthermore, all subsequent interactions between the terminal device and the blockchain network can be achieved through the SDK.

[0147] Step S102: Generate the public key corresponding to the first object and the account address corresponding to the first object based on the private key.

[0148] Specifically, a feasible implementation process for generating the public key and account address corresponding to the first object based on the private key can be as follows: Asymmetric encryption is performed on the private key to obtain the public key corresponding to the first object; one-way hash encryption is performed on the public key to obtain the account address corresponding to the first object. Asymmetric encryption means that encryption and decryption use different keys, one as the public key and the other as the private key. Information encrypted with the public key can only be decrypted with the private key, and vice versa. Common asymmetric encryption methods include ECC (Elliptic Curve Cryptography) and RSA (a public-key cryptography algorithm), etc., which are not limited here. Hash encryption refers to performing a hash function on the public key to obtain the account address. It should be noted that when the terminal device needs to send transactions or requests to the blockchain network, it needs to sign with the private key to prove ownership. This signature is unforgeable and can be verified by the public key corresponding to the private key. Furthermore, an account address can only have one private key, and this signature cannot be changed.

[0149] To better understand the creation process of the above identity account system (including private key, public key, and account address), please refer to [link / reference needed]. Figure 5 , Figure 5 This is a schematic diagram illustrating the creation process of a social identity account system provided in an embodiment of this application. For example... Figure 5 As shown, terminal device 50 (which can be the above-mentioned) Figure 2In the terminal device cluster 10 shown, for example, terminal device 20 can be an application client 51 with a social application and a blockchain SDK (Software Application Development Kit) 52 integrated in terminal device 10b). Terminal device 50 responds to the account application operation of the first object through the application client 51, and then sends an account registration request to the blockchain SDK 52. The blockchain SDK 52 responds to the account registration request and can first store a private key 53 according to the blockchain rules, and then perform one-way elliptic curve multiplication on the private key 53 (i.e., the above asymmetric encryption processing) to obtain the public key 54. Then, one-way hash function operation (i.e., the above hash encryption processing) is performed on the public key 54 to obtain the account address 55. Then, the blockchain SDK 52 can return the private key 53, the public key 54 and the account address 55 to the application client 51.

[0150] pass Figure 5 The creation process shown demonstrates that application client 51 can directly generate the corresponding account address and public / private keys according to blockchain rules via blockchain SDK 52. The entire process bypasses the backend server of application client 51; the calculations are completed within blockchain SDK 52, achieving decentralization of the social application's identity account system. Subsequent requests or transactions associated with this account address, which can also be considered as requests or transactions initiated by the first object, all require the signature of this private key to be sent to the blockchain network. The blockchain network then verifies the signature based on the public key.

[0151] Step S103: Send an account registration transaction for the first object to the blockchain network according to the private key, the public key and the account address, so that the blockchain network packages the account registration transaction into the target block and performs consensus on the target block.

[0152] Specifically, after the terminal device generates the identity account system of the social application designed in this embodiment for the first object, the first object's account registration is not yet successful. The terminal device still needs to send an account registration transaction to the blockchain to indicate that the account is registered. Only when the account registration transaction is successfully written into the blockchain is the first object's account registration considered to be initially completed, but it still needs to wait for the social application's backend server to make a final confirmation.

[0153] Specifically, a feasible implementation process for sending an account registration transaction for a first target to the blockchain network based on a private key, public key, and account address, so that the blockchain network packages the account registration transaction into the target block and performs consensus on the target block, can be as follows: Generate an account registration request; the account registration request carries the public key and account address; sign the account registration request using the private key to obtain signature data; package the account registration request and signature data to obtain the account registration transaction for the first target; send the account registration transaction to the blockchain network so that the blockchain network verifies the signature data using the public key to obtain a verification result; if the verification result is successful, package the account registration transaction into the target block and perform consensus on the target block.

[0154] Step S104: If a registration success message is received from the backend server corresponding to the social application, the account address is determined as a social account; the private key, the public key, and the social account are used to provide the first object with the ability to perform social interactions in the social application; the registration success message is generated by the backend server when the consensus on the target block is successfully uploaded to the blockchain.

[0155] Specifically, successful account registration for the first party requires confirmation from the social application's server-side, i.e., the corresponding backend server. For the backend server to collect information about registered users, it only needs to traverse the blockchain's block information and collect the information of accounts marked as registered. Understandably, the backend server can traverse the blockchain at a fixed frequency, or it can wait to receive a notification of a new block being added to the blockchain network before traversing it; this application does not impose any restrictions. When the backend server traverses the blockchain and encounters an account registration transaction in the target block for the first time, it can obtain the account identity information of the first party carried in the first party's account registration transaction, generate a registration success message, and then send it to the terminal device.

[0156] Specifically, after receiving a registration success notification from the backend server, the terminal device can log in to the social application using its account address as the primary user account. Subsequently, after the primary user logs in to the social application using this social account, the aforementioned identity account system (private key, public key, and social account) can be used to provide the primary user with the ability to perform social interactions within the social application. These social interactions include all online social interactions performed by the primary user through the social application, such as posting social information, adding users, and engaging in real-time conversations. Because the primary user's identity account system for the social application is already decentralized, social interactions can also be decentralized based on this identity account system, thereby achieving the decentralization of the entire social application.

[0157] Optionally, when the first object performs a social information publishing operation, the terminal device can respond to the first object's social information publishing operation through its social account, generating a social information publishing request, which includes the information to be published. The terminal device can then obtain the private key corresponding to the first object, and sign the social information publishing request using the private key to obtain social information publishing signature data. The social information publishing request and the social information publishing signature data are then packaged together to obtain a social information publishing transaction. The terminal device can then send the social information publishing transaction to the blockchain network, which will package the transaction into a social block and then perform consensus and on-chain processing of the social block. Afterwards, if the terminal device receives a social information publishing instruction from the backend server carrying the information to be published and the block hash of the social block, it will display the information to be published and the block hash in the social application according to the instruction. This social information publishing instruction is generated by the backend server when it successfully traverses the social block and achieves consensus on-chain processing; the block hash can be used to query the block information of the social block.

[0158] To facilitate understanding of the process of publishing social information, we will use publishing a post as an example. Please refer to [link / reference]. Figure 6 , Figure 6 This is an interactive diagram illustrating a post publishing implementation provided in an embodiment of this application. For example... Figure 6 As shown, the interaction process mainly includes the following steps S61-S64:

[0159] Step S61: The terminal device requests the blockchain network to upload the post to the blockchain.

[0160] Specifically, the terminal device can respond to the first object's post publishing operation by generating a post publishing request, which includes the post the first object intends to publish. Then, the terminal device can obtain the first object's private key through the integrated blockchain-related SDK, sign the post publishing request to obtain post publishing signature data, and package the signature data and the post publishing request into a post publishing transaction. Finally, the terminal device directly sends this post publishing transaction to the blockchain network via the blockchain SDK, thereby applying to put the post on the chain. This ensures that the data in the post cannot be tampered with and exists permanently on the blockchain.

[0161] Step S62: The background server polls for new blocks in the blockchain network.

[0162] Specifically, whenever a new block is added to the blockchain network, the backend server can iterate through the new block and read its transactions. In other words, the backend server continuously polls the blockchain for new blocks, parses each new block, and stores the valid data in the corresponding database according to the social data structure design. Although the data is still stored in the server-side database, the original data is on the blockchain and can be verified. Therefore, simply tampering with the database is meaningless.

[0163] Step S63: The backend server iterates through the post publishing transactions, retrieves the post publishing transactions, and parses the post information.

[0164] In step S64, the backend server issues a display command, and the terminal device displays the post to the first target.

[0165] Specifically, terminal devices can retrieve data from the backend server using traditional methods such as calling APIs (interfaces) for display. Optionally, each piece of data can be appended with a block hash. Clicking the hyperlink directly takes you to the block explorer to view the block information. In other words, the posts seen by the terminal device can be appended with the block hash of the block to which the transaction published the post belongs. When a first party has doubts about the authenticity of the content displayed in the post, they can verify it on the blockchain using this block hash.

[0166] Understandably, in order to ensure the decentralization of social applications, in addition to the decentralization of the identity account system, the design of the friend network of an object should also adopt a decentralized approach. One feasible approach is to establish peer-to-peer (P2P) connections directly between terminal devices. In this way, social interactions such as adding or deleting objects and instant conversations between objects can be achieved based on peer-to-peer connections without going through the backend server of the social application. The object's object list can be stored on the blockchain or cached on the terminal device without being affected by the backend server.

[0167] Optionally, when the first object performs an object addition operation, the terminal device can respond to the object addition operation performed by the first object through its social media account, generating an object addition request that includes the second object's social media account. Then, it establishes an object peer-to-peer connection with the object terminal device bound to the second object. If the object peer-to-peer connection is successfully established, an object addition request is sent to the object terminal device through the object peer-to-peer connection, causing the object terminal device to respond to the object addition request and perform the object addition operation, thus obtaining the object addition result. If the object addition result is that the object refuses to add, then the object addition is determined to have failed. If the object addition result is that the object allows to add, then the private key of the first object is obtained, and the object is allowed to add based on the private key. The result is signed to obtain the addition result signature data; the object addition permission result and the addition result signature data are packaged together to obtain the first object addition permission transaction; the first object addition permission transaction is sent to the blockchain network so that the blockchain network can reach a consensus on the first object addition permission transaction and put it on the chain; if the object addition success instruction is received from the backend server, the social media account of the second object is added to the object list of the first object according to the object addition success instruction; the object addition success instruction is generated by the backend server when it determines that the first object addition permission transaction and the second object addition permission transaction have been successfully consensused and put on the chain; the second object addition permission transaction is generated by the object terminal device according to the object addition permission result.

[0168] To facilitate understanding of the decentralized implementation process of adding objects as described above, we will use the example of adding object B (which can be the first object mentioned above) to object A (which can be the second object mentioned above) as an illustration. Please refer to [link / reference needed]. Figure 7 , Figure 7 This is a schematic diagram illustrating an object addition implementation provided in an embodiment of this application. Assume that terminal device a is bound to object A, and terminal device b is bound to object B. For example... Figure 7 As shown, the process of adding this object mainly includes the following steps S71-S76.

[0169] In step S71, terminal device a responds to the input operation of object A, obtains the social media account of object B, and then generates an object add request carrying the social media account of object B.

[0170] Step S72: The blockchain node receives the object addition request sent by terminal device a, and determines whether object B's social media account is registered. If object B's social media account is registered, then proceed to step S74; if object B's social media account is not registered, then proceed to step S73.

[0171] Specifically, a blockchain node can query the social media account of object B in the blockchain ledger. If a transaction is found that corresponds to the social media account of object B, then it is confirmed that the social media account of object B has been registered.

[0172] Step S73: The blockchain node sends an "Account Not Found" message to terminal device a, ending the object addition process.

[0173] Step S74: Terminal device a establishes a peer-to-peer connection with terminal device b; if the peer-to-peer connection is established successfully, proceed to step S75; if the peer-to-peer connection fails to be established, the object addition process fails, and all processes end.

[0174] Specifically, when terminal device A establishes a peer-to-peer (P2P) connection with terminal device B, neither device A nor B knows the other's IP address and port information, and therefore cannot directly establish a connection request. At this point, a trusted third-party device is needed to obtain the other's IP address and port information. This third-party device stores social media accounts and the corresponding IP addresses and port information of the terminal devices associated with those accounts. This third-party device can be a dedicated communication server, a backend server as mentioned above, or a blockchain node in a blockchain network. Both terminal devices A and B establish a connection with the third-party device, informing it of the social media account they wish to connect to. The third-party device then obtains the IP address and port information of the terminal device associated with the desired social media account and returns it to the corresponding terminal device. In this way, both terminal devices A and B can obtain each other's IP address and port information, thus establishing a P2P network connection.

[0175] Specifically, terminal device A will actively establish a P2P network connection with terminal device B. If the connection fails to be established, the object addition will fail. Optionally, terminal device A can cache the object addition request and continue the object addition operation the next time it initiates a P2P connection with terminal device B.

[0176] In step S75, terminal device a sends an object add request to terminal device b through an object point-to-point connection.

[0177] Step S76: Terminal device b responds to object B's selection operation for the object addition request, determines the object addition result. If the object addition result is that the object refuses to add, the object addition is determined to have failed, and all processes end; if the object addition result is that the object allows to add, then step S77 is executed.

[0178] Specifically, after receiving the request to add an object, terminal device B can display a pop-up window waiting for object B to make a selection, i.e., whether to agree to add object A as a friend.

[0179] In step S77, both terminal device a and terminal device b send an object to allow the addition of a transaction to the blockchain network for on-chain processing.

[0180] Step S78: The object is allowed to be added to the blockchain successfully. Terminal device a and terminal device b update the object list stored locally and end all processes.

[0181] Specifically, terminal device a will add object B's social media account to object A's object list, and terminal device b will add object A's social media account to object B's object list.

[0182] It's understandable that each terminal device can maintain a local object list and object grouping information. When communication is needed, it can directly retrieve object information from its local cache, establish a P2P connection, and then send a message. The blockchain updates the relevant object list each time a terminal device adds or deletes friends. The object list cached locally on the terminal device can also be periodically synchronized from the blockchain to its local machine.

[0183] Optionally, when the first object performs an instant conversation operation, the terminal device can respond to the first object's instant conversation operation via social media account by displaying the first object's object list; respond to the trigger operation targeting the social media account of the second object in the object list by displaying the instant conversation interface with the second object; respond to the first object's conversation message generation operation by generating an instant conversation message; and send the instant conversation message to the object's terminal device via an object-to-object peer-to-peer connection. The instant conversation message can include text, video, voice, etc. It can be understood that the sending of instant conversation messages does not require forwarding through the backend server of the social application, but directly achieves peer-to-peer communication and exchange through object-to-peer connections, thereby realizing the decentralization of online social networking.

[0184] Using the method provided in this application embodiment, when responding to a first object's account registration request for a social application, a private key is generated for the first object based on blockchain rules. Further, a public key and an account address corresponding to the first object are generated based on the private key. The blockchain rules are stored in the terminal device corresponding to the first object. Then, an account registration transaction for the first object is sent to the blockchain network based on the private key, public key, and account address. The blockchain network packages the account registration transaction into the target block and performs consensus on the target block. If a registration success notification is received from the backend server corresponding to the social application, the account address is identified as a social account. This private key, public key, and social account are used to provide the first object with the ability to perform social interactions within the social application. The registration success notification is generated by the backend server when it reaches the target block and successfully completes consensus on the blockchain. Therefore, the object's account information is stored in the blockchain. Even if the backend server is attacked, the object's account information will not be lost, achieving decentralization of the object's social account. Furthermore, subsequent social interactions based on the private key, public key, and social account can continue to be recorded on the blockchain, thus achieving decentralization of the object's online social interactions.

[0185] Furthermore, from the above Figure 4 As described in the corresponding embodiments, the private key of the first object is not customized by the first object, but generated by the terminal device. It is generally long and complex, making it difficult for the first object to directly remember the private key. However, directly storing the first object's private key on the terminal device is insecure and prone to leakage. Therefore, embodiments of this application allow the first object to customize a password, which is used to encrypt and store the first object's private key. Please refer to... Figure 8 , Figure 8 This is a flowchart illustrating a blockchain-based data processing method provided in an embodiment of this application. The method can be implemented by a terminal device (e.g., the one described above). Figure 2 This method is executed by any terminal device in the terminal device cluster 10 of the corresponding embodiment. The following description uses the execution of this method by a terminal device as an example. The blockchain-based data processing method may include at least the following steps S201-S204:

[0186] Step S201: The password setting page for the social media account of the first person is displayed.

[0187] Specifically, upon successful registration of the first user's account, the terminal device can display a password setting page for that user's social media account. Through this page, the user can customize their password. Optionally, the password setting page can also display password requirements, such as a minimum password length of 8 characters and the inclusion of uppercase and lowercase letters.

[0188] Step S202: In response to the input operation of the first object on the password setting page, obtain the password entered by the first object as the first password.

[0189] Step S203: Perform reversible encryption on the private key according to the first password to obtain the first encrypted file.

[0190] Specifically, the first cipher acts as an encryption factor to reversibly encrypt the private key. Reversible encryption means that the encrypted data, after being encrypted using the encryption factor, can be decrypted using the same encryption factor to restore the original data.

[0191] Step S204: Store the first encrypted file. After the first encrypted file is successfully stored, display a password setting success message on the password setting page.

[0192] Specifically, it can be understood that the terminal device will store the first encrypted file. In subsequent social interaction operations, the first person only needs to enter the first password, and the terminal device can obtain the first person's private key by decrypting the first encrypted file.

[0193] Using the method provided in this application embodiment, the first object does not need to remember a relatively complex private key, but only needs to remember a custom first password. The terminal device reversibly encrypts the first object's private key based on the first password and only stores the encrypted first encrypted file, reducing the risk of private key leakage.

[0194] Furthermore, there are various reversible encryption methods. Using a single reversible encryption method is easily cracked. Therefore, an encryption pool can be designed, containing multiple encryption methods. The first object can define a custom random code to match the encryption methods in the pool, increasing the difficulty of cracking the encrypted file corresponding to the private key. For easier understanding, please refer to [link to documentation]. Figure 9 , Figure 9 This is a flowchart illustrating a blockchain-based data processing method provided in an embodiment of this application. The method can be implemented by a terminal device (e.g., the one described above). Figure 2 This method is executed by any terminal device in the terminal device cluster 10 in the corresponding embodiment. The following description uses the execution of this method by a terminal device as an example. The blockchain-based data processing method may include at least the following steps S301-S305:

[0195] Step S301: Display the password setting page for the social media account; the password setting page includes a password setting text box and a random code setting text box.

[0196] Step S302: In response to the first object's setting operation on the password setting text box, obtain the password set by the first object as the second password; in response to the first object's setting operation on the random code setting text box, obtain the random code set by the first object as the target random code.

[0197] Step S303: Obtain an encryption method that matches the target random code from the encryption pool and use it as the target encryption method; perform reversible encryption processing on the private key according to the second password and the target encryption method to obtain the second encrypted file.

[0198] Specifically, the encryption pool contains multiple encryption methods. The terminal device can use a specific algorithm, such as modulo or hash, to select a particular encryption method from the pool as the target encryption method. Based on the target encryption method and the second password, the terminal device can then perform reversible encryption of the private key to obtain the second encrypted file.

[0199] Step S304: Associate and store the second encrypted file, the target random code, and the social media account of the first object.

[0200] Step S305: After the second encrypted file, the target random code, and the social media account of the first object are successfully associated and stored, a password setting success message is displayed on the password setting page.

[0201] Optionally, in response to the first object's social interaction on-chain operation for a social application, a social interaction on-chain request is generated; a password input text box is displayed in the social application; in response to the first object's input operation for the password input text box, the password entered by the first object is obtained as the input password; if the input password is the same as the second password, the second encrypted file and the target random code associated with the first object's social account are obtained; the target encryption method matching the target random code is obtained from the encryption pool; the second encrypted file is reversibly decrypted according to the input password and the target encryption method to obtain the private key; the social interaction on-chain request is signed using the private key to obtain social interaction signature data; the social interaction on-chain request and the social interaction signature data are packaged to obtain a social interaction on-chain transaction; the social interaction on-chain transaction is sent to the blockchain network, and the blockchain network packages the social interaction on-chain transaction into a new target block, and performs consensus on the new target block. In short, after the terminal device stores the second encrypted file, in subsequent social interaction on-chain operations, the first object only needs to enter the second password, and the terminal device can obtain the first object's private key by decrypting the second encrypted file.

[0202] As described above, the terminal device does not directly store the private key. Instead, it generates a second encrypted file corresponding to the private key based on the second password set by the first object and the target random code, and then saves the second encrypted file to improve the security of private key storage. When the first object needs to change terminal devices, it can directly transfer the second encrypted file to the transfer terminal device. Optionally, the terminal device can respond to the first object's account transfer operation on the transfer terminal device, generate a target transfer code, and then establish a peer-to-peer connection with the transfer terminal device to receive the response transfer code sent by the transfer terminal device through the peer-to-peer connection. If the response transfer code is the same as the target transfer code, the second encrypted file, the target random code, and the social account are sent to the transfer terminal device. The transfer terminal device can then obtain the verification password entered by the first object, perform reversible decryption processing on the second encrypted file based on the verification password and the target random code to obtain the decryption private key, and send a verification transaction to the blockchain network based on the decryption private key and the first object's social account. If a transfer success notification is received from the transfer terminal device, the account transfer is confirmed to be successful. This transfer success notification is generated by the transfer terminal device when it confirms that the verification transaction has been successfully uploaded to the blockchain.

[0203] To better understand the above private key transfer process, please refer to [link / reference]. Figure 10 , Figure 10 This is an interactive schematic diagram of private key transfer provided in an embodiment of this application. Suppose a first user wants to change their terminal device from terminal device 1 to terminal device 2. To continue using the social application normally on terminal device 2, they need to transfer their private key, specifically, the second encrypted file corresponding to the private key, from terminal device 1 to terminal device 2. For example... Figure 10 As shown, the interaction between terminal device 1 and terminal device 2 during this transfer process mainly includes the following steps S1-S6:

[0204] In step S1, terminal device 1 can respond to the account transfer operation of the first object for terminal device 2 and generate a target transfer code.

[0205] Specifically, the target transfer code is used to verify the identity of the recipient.

[0206] Step S2: Terminal device 1 and terminal device 2 establish a point-to-point (P2P) connection.

[0207] In step S3, terminal device 2 sends the response transfer code input by the first object to terminal device 1.

[0208] Step S4: If terminal device 1 determines that the response transfer code and the target transfer code are the same, it sends the social account, the second encrypted file, and the target random code to terminal device 2.

[0209] In step S5, terminal device 2 obtains the verification password input by the first object, and then verifies the correctness of the private key based on the verification password.

[0210] Specifically, after receiving the file, terminal device 2 will display a password input box, prompting the user to enter a previously set second password for verification. Then, terminal device 2 will obtain the verification password entered by the first party. Based on the verification password and the target random code, it can reversibly decrypt the second encrypted file to obtain the decryption private key. At this point, terminal device 2 needs to send a verification transaction to the blockchain to represent the change of the first party's terminal device. If the verification transaction is successfully recorded on the blockchain, it means that the verification private key is correct, and the transfer is successful.

[0211] Step S6: If terminal device 2 determines that the private key is correct, it sends a transfer success message to sending terminal device 1.

[0212] Optionally, the system displays a password cloud storage page for the social media account; responds to input on the password cloud storage page to obtain the available contact account of the first target; performs reversible encryption on the second password based on the available contact account and the target encryption method to obtain a third encrypted file; sends the third encrypted file and the available contact account to the backend server corresponding to the social application, and then the backend server associates and stores the third encrypted file and the available contact account; if a storage success message is received from the backend server, the storage success message is displayed. The available contact account can include an email address, phone number, etc. In short, using the target encryption method determined by the previously determined target random code, and using the available contact account as an encryption factor, the second password is encrypted into ciphertext to obtain the third encrypted file, which is then submitted to the backend server for storage. In this way, even if the backend server possesses the third encrypted file and the available contact account, it does not know the target encryption method and therefore cannot decrypt the second password of the first target.

[0213] Optionally, the system displays a password recovery page for social media accounts; responds to input operations on the password recovery page, retrieves the recovery account entered by the first user; sends the recovery account to the backend server; if the backend server detects that the recovery account matches an available contact account, it retrieves a third encrypted file, generates a recovery verification code for the third encrypted file, and sends the verification code to the input recovery account; if the system receives a verification code notification from the backend server, the terminal device displays a verification code input box on the password recovery page; responds to input operations on the verification code input box, retrieves the verification code entered by the first user; sends the verification code to the backend server; if the backend server verifies that the input verification code and the recovery verification code match, it receives the third encrypted file returned by the backend server; performs reversible decryption processing on the third encrypted file according to the input recovery account and the target encryption method to obtain a second password, and displays the second password on the password recovery page. In short, when the first user attempts to retrieve their password, the backend server first sends a retrieval verification code to the user's available contact account. The user then submits the verification code to complete identity verification. If the verification is successful, the backend server returns a third encrypted file. Once the terminal device receives this third encrypted file, it can use the available contact account as an encryption factor and the target encryption method determined by the previously selected random code to decipher the second password.

[0214] Optionally, you can also reset the password for your social media account, discarding the second password and generating a new one. The password reset function simply requires using the second password and the target encryption method to decipher the private key. Then, the key saving process is repeated. Finally, a new encrypted file containing the private key is generated using the new password.
