[0118] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0119] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0120] In related technologies, if an application chain needs to be deployed based on blockchain, a cloud server needs to be purchased separately. Then, a blockchain operating environment needs to be developed through the cloud server, and the application chain needs to be deployed in the blockchain operating environment. Since the cloud resources in the cloud server are usually large, it is not only costly but also leads to resource waste. At the same time, developing a blockchain operating environment is not only costly but also difficult, resulting in high deployment costs for the application chain.

[0121] To address the aforementioned problems, this invention provides a node deployment method based on a first server, a node deployment method based on a second server, an application chain deployment method based on a third server, and a node control method based on a fourth server. The following are various embodiments of the methods described in this application.

[0122] Reference Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the method proposed in this invention. In this embodiment, the method includes the following steps:

[0123] Step S11: The first server receives the technology application information.

[0124] The first server includes the BSN (Blockchain-based Service Network) city node management system. It should be understood that BSN is a global public infrastructure network for deploying and running blockchain applications, connecting all data centers through a set of blockchain operating environment protocols. It spans cloud services, portals, and underlying frameworks.

[0125] The BSN City Node Management System is a city node management system for the Blockchain Service Network (BSN). It assists cloud service providers in connecting their cloud resources to the BSN, enabling the creation of public city nodes based on these BSN-connected cloud resources. These public city nodes then provide application chain deployment services. The BSN City Node Management System is publicly accessible; cloud service providers can register accounts on the system and submit technical applications through it.

[0126] In one example, the first server may include a database server and a file server to deploy the BSN city node management system. The BSN city node management system program can be designed based on the Spring+SpringMVC+Mybatis open source framework. The BSN city node management system can adopt a RESTful style interface for uploading and storing data.

[0127] The technical application information includes cloud resource information, which allows for the location of corresponding cloud resources. In some implementations, cloud resource information may include the following three categories: resource information, pricing information, and service provider information. Resource information is related to cloud resource configuration and may include at least one of the following: resource location information, cloud service provider, and cloud server configuration information. Pricing information refers to the billing standard for cloud resources, which can be set based on at least one of the following: the number of accounting nodes, the TPS (Transactions Per Second), the storage capacity, and the bandwidth. Pricing information may include at least one of the following: a billing standard based on accounting nodes, a billing standard based on TPS, a billing standard based on storage capacity, and a billing standard based on bandwidth. Service provider information is related to the service provider offering the cloud resource, and may include Level 3 information security certification and qualification certificates, which prove that the service provider is qualified to provide cloud services.

[0128] In this embodiment of the invention, in order to connect cloud resources to the blockchain service network and thereby establish public city nodes to provide application chain deployment services based on public city nodes, cloud service providers can submit technical applications in the BSN city node management system of the first server, and the first server receives technical application information through the BSN city node management system.

[0129] In some implementations, a single technology application establishes one public city node. If multiple public city nodes need to be deployed, multiple technology applications can be submitted. Of course, in other implementations, a single technology application can also establish multiple public city nodes.

[0130] Step S12: The first server sends a construction instruction to the second server based on the technology application information.

[0131] The second server includes the BSN Operations and Maintenance Management System. The BSN Operations and Maintenance Management System is a blockchain service network operations and maintenance management system, located within the blockchain service network, used to manage public city nodes and other components within the network.

[0132] In this embodiment of the invention, after receiving the technology application information through the BSN city node management system, the first server sends a construction instruction to the second server based on the technology application information, so that the second server can construct a public city node in the blockchain service network based on the construction instruction and cloud resource information.

[0133] Step S13: Based on the assembly instructions and cloud resource information, the second server assembles a public city node in the blockchain service network to provide application chain deployment services.

[0134] It should be noted that public city nodes are the basic operating units of the blockchain service network. Their main function is to provide system resources such as access control, transaction processing, ledger storage, and computing power for the operation of blockchain applications. The owner of each public city node is a provider of cloud resources or a data center.

[0135] In this embodiment of the invention, after receiving the assembly instruction sent by the first server, the second server, based on the cloud resources corresponding to the cloud resource information, assembles a public city node in the blockchain service network. The public city node can be used to provide application chain deployment services, thereby enabling the public city node to access the blockchain service network. In other words, in this embodiment, cloud service providers can connect their cloud resources to the blockchain service network based on the BSN city node management system on the first server, thus achieving free choice in accessing the blockchain service network. In some examples, cloud service providers can also submit a withdrawal application based on the BSN city node management system, thereby removing cloud resources already connected to the blockchain service network. The processing steps for withdrawal applications by the first and second servers are similar to the processing steps for technical applications.

[0136] It is worth noting that when the second server establishes a public city node in the blockchain access network based on the cloud resources corresponding to the cloud resource information, it can install public city node software on the cloud resources corresponding to the cloud resource information to deploy the functional modules required for the public city node, thereby establishing the public city node. The public city node software can be developed based on actual needs.

[0137] In some implementations, a public city node may include the following functional modules: a blockchain underlying framework module, an accounting node, a system permission chain, a CA (Certificate Authority) management module, a node gateway, and a city node management module.

[0138] The underlying blockchain framework module contains the underlying blockchain framework.

[0139] Each public city node deploys a ledger node. For each blockchain underlying framework, a corresponding ledger node is configured. In this way, through the channel, group or sub-chain mechanism of each blockchain underlying framework, each ledger node can serve multiple application chains. While ensuring that the transaction processing, smart contracts and ledger data of each application chain are completely isolated from other application chains, all application chains share system resources.

[0140] The system permission chain, serving as the underlying management chain, is deployed across all public city nodes. It stores users' application access keys (public keys) and application permission configurations. When a user connects to a node gateway, the gateway verifies the user's identity, allowing only authorized application chains to access them, and invoking the corresponding smart contract methods according to the application chain's permission configuration.

[0141] Each public city node deploys a unified CA management module for the full lifecycle management of user transaction keys for all application chains within that public city node, including: generating, issuing, updating, and revoking user transaction keys. User transaction keys are used for data encryption and signing when users access the application chain.

[0142] A node gateway serves as the entry point for data interaction between business systems outside the blockchain service network and application chains deployed within it. Each public city node has a node gateway, and users can choose any public city node where their application chain is deployed to access the blockchain service network, based on proximity. Public city node gateways can verify user identities and also provide functions such as transaction authentication, transaction routing, rate limiting, load balancing, gateway APIs (Application Programming Interfaces), and SDKs (Software Development Kits).

[0143] The city node management module is used to connect with the BSN operations and maintenance management system. After receiving instructions from the portals of various blockchain service networks, the BSN operations and maintenance management system manages each public city node through the city node management module. This includes managing application chains, deploying smart contracts, configuring ledger nodes, managing key certificates, setting application permissions, and obtaining operational information.

[0144] Features of public city nodes: They save on the deployment and maintenance costs of blockchain applications, each deployed application chain is isolated from each other, the complexity is encapsulated and hidden from the outside world, they provide flexible and convenient access methods, and they have a fast one-stop networking processing mechanism.

[0145] In some implementations, after the establishment of public city nodes, if the resource usage within the public city nodes tends to be saturated, the cloud service provider can also increase cloud resources through the BSN city node management system to improve the load capacity of the public city nodes.

[0146] It should be noted that, in this embodiment of the invention, the steps of the first server can be executed based on the BSN city node management system, and the steps of the second server can be executed based on the BSN operation and maintenance management system.

[0147] In the method provided by this embodiment of the invention, a first server receives technical application information and sends a construction instruction to a second server based on the technical application information. The technical application information includes cloud resource information. The first server includes a BSN city node management system, and the second server includes a BSN operation and maintenance management system. After receiving the construction instruction, the second server, based on the construction instruction and the cloud resource information, constructs a public city node in the blockchain service network to provide application chain deployment services. This enables the public city node to be connected to the blockchain service network. Furthermore, if an application chain needs to be deployed, cloud resources can be selected from the public city nodes of the blockchain service network as needed for application chain deployment. There is no need to purchase a separate cloud server, develop a blockchain operating environment based on the purchased cloud server, or deploy the application chain based on the developed blockchain operating environment, thus saving costs and increasing resource utilization.

[0148] Based on the first embodiment, a second embodiment of the method of the present invention is proposed. To ensure the authenticity of the technology application information and avoid situations where inaccurate technology application information leads to the inability to establish public city nodes or attacks on the blockchain service network, in this embodiment of the invention, the technology application information can be reviewed before step S12. Step S12 is then executed only after the review is passed. The specific review method can be flexibly set according to actual needs.

[0149] For example, in some implementations, the first server may review the technology application information, and after the review is passed, step S12 is executed.

[0150] Alternatively, in some implementations, to enhance the scrutiny of technology application information and further improve its authenticity, see [reference needed]. Figure 2 As shown, prior to step S12, the node deployment method may also include the following steps:

[0151] Step S21: The first server sends the technology application information to the second server.

[0152] After receiving the technology application information, the first server sends the technology application information to the second server so that the second server can perform the first verification of the technology application information.

[0153] Step S22: The second server conducts the first review of the technology application information.

[0154] After receiving the technology application information sent by the first server, the second server conducts the first review of the technology application information.

[0155] When the second server reviews the technical application information, it can verify the authenticity of the cloud resource information in the technical application information. For example, assuming that the cloud resource information includes resource location information, cloud service provider, cloud server configuration information, Level 3 information security certification and qualification certificate documents, it can verify whether the corresponding resource can be found based on the resource location information, whether the cloud service provider is correct, whether the cloud server configuration information is accurate, whether the Level 3 information security certification is genuine, and whether the qualification certificate documents are genuine.

[0156] Step S23: When the first review result is "approved", the first server conducts a second review of the technology application information.

[0157] The first server will only conduct a second review of the technology application information if the second server conducts the first review and the first review result is "approved".

[0158] In this process, after the second server conducts its first review of the technology application information, it can send the review result to the first server so that the first server can determine whether the first review result is approved; or, after the second server conducts its first review of the technology application information, it can send an approval notification to the first server so that the first server can determine whether the first review result is approved.

[0159] When the first server reviews the technology application information, it can do so based on preset review rules. These preset review rules can be flexibly set according to actual needs. For example, if cloud resources or bandwidth are too small, it will be impossible to build public city nodes. The preset review rules can include cloud resource thresholds and / or bandwidth thresholds. If the cloud resources or bandwidth in the technology application information are less than the cloud resource threshold or less than the bandwidth threshold, the review will be deemed unsuccessful. Similarly, if the price information in the technology application information is set unreasonably, it will affect market order. Therefore, the preset review rules can also include preset conditions for price settings. The first server reviews whether the price information in the technology application information meets these preset conditions.

[0160] Step S24: If the second audit result is "approved", proceed to step S12.

[0161] By reviewing the technology application information through both a second server and a first server, the accuracy and security of the technology application information are improved. Furthermore, by first reviewing the technology application information through the second server and then reviewing it through the first server when it is approved, the amount of data processing can be reduced and the response speed can be improved.

[0162] It should be noted that if the first or second review fails, the cloud service provider can be notified to modify the technical application information. After modification, the application will be reviewed again. It should be noted that the review process involves returning to step S21 to conduct the first and second reviews again.

[0163] In the method provided by this invention, after the first server receives the technology application information through the BSN city node management system, it will send a construction instruction to the second server based on the technology application information only after the technology application information has been approved. This allows the second server to improve the accuracy and security of the technology application information based on the construction instruction and cloud resource information.

[0164] Based on the foregoing embodiments, a third embodiment of the method of the present invention is proposed. In this embodiment of the present invention, before step S11, see [link to previous section]. Figure 3 As shown, it also includes:

[0165] Step S31: The first server receives the business application information.

[0166] It should be noted that business application information includes contact information and cloud service provider information. In some scenarios (e.g., when a technical application is approved, or when the cloud resources corresponding to the information are purchased), the contact person can be reached promptly based on the contact information. The cloud service provider is the service provider of the cloud resources corresponding to the information, i.e., the owner of the cloud resources. Cloud service provider information includes information related to the cloud service provider, which may include the provider's name, relevant qualification certificates, etc.

[0167] To verify the authenticity of the cloud service provider, in this embodiment of the invention, before receiving the technology application information, the cloud service provider may also submit business application information through the BSN city node management system on the first server.

[0168] Step S32: The first server reviews the business application information.

[0169] After receiving the business application information, the first server reviews the application information, such as verifying whether the cloud service provider is genuine and whether it has the qualifications to provide cloud services.

[0170] Step S33: After the business application information is approved, proceed to step S11.

[0171] In this embodiment of the invention, step S11 is executed only after the business application information has been approved.

[0172] In some implementations, in order to perform operations on the BSN city node management system of the first server to trigger business applications, technical applications, etc., the cloud service provider can first register and activate an account on the BSN city node management system. Then, the cloud service provider can log in to the BSN city node management system based on the activated account to perform subsequent business applications, technical applications, and other operations.

[0173] The account activation method can be flexibly set according to actual needs. In some examples, registration can be made on the BSN city node management system based on email. After receiving the registration request, the BSN city node management system sends an email to the registered email address, which includes an account activation link. By triggering the account activation link, the account can be activated.

[0174] In this embodiment of the invention, the first server receives business application information, reviews the business application information, and only receives technology application information after the review is passed, thereby ensuring the authenticity of the cloud service provider making the technology application and thus improving security and reliability.

[0175] Based on the foregoing embodiments, a fourth embodiment of the method of the present invention is proposed. In this embodiment, before step S13, the following steps may be included:

[0176] Step S41: The second server receives the underlying blockchain framework.

[0177] It should be noted that in this embodiment of the invention, the public city nodes are equipped with all underlying blockchain frameworks that are connected to the blockchain service network. These underlying blockchain frameworks include, but are not limited to, at least one of the following: Hyperledger Fabric (an open-source distributed ledger), FISCO BCOS (the blockchain platform of the China Blockchain Association), Chinese Cryptocurrency Fabric, CITA, Wutong Chain, Brochain, XuperChain, Ethereum, and EOS (Enterprise Operation System, a commercially available distributed blockchain operating system). It should also be noted that CITA is an enterprise-level blockchain product prototype independently developed by Cryptope, one of the founding members of the EEA (Enterprise Ethereum Alliance). XuperChain is the underlying blockchain technology architecture developed by Baidu.

[0178] A blockchain underlying framework can be viewed as the operating system of blockchain applications. Types of blockchain underlying frameworks include public blockchain frameworks and permissioned blockchain frameworks. For public blockchain frameworks, developers can purchase relevant resources within the portal of any blockchain service network, choose any public blockchain framework, establish public blockchain nodes, and connect to the mainnet of those nodes. Alternatively, depending on the flexibility of the chosen public blockchain framework, developers can build their own public blockchain network on the blockchain service network and continuously establish more nodes within or outside of that network.

[0179] To enable the developed blockchain underlying framework to be connected to the Blockchain Service Network and installed on public city nodes, the blockchain underlying framework developer can upload the completed blockchain underlying framework to the BSN operation and maintenance management system, and the second server receives the blockchain underlying framework through the BSN operation and maintenance management system.

[0180] Step S42: The second server standardizes the underlying blockchain framework according to the preset underlying framework adaptation standard.

[0181] The preset underlying framework adaptation standard is a pre-set guideline that standardizes different blockchain underlying frameworks.

[0182] After receiving the underlying blockchain framework, the second server standardizes it according to a pre-defined framework adaptation standard. This allows the underlying blockchain framework to connect to the Blockchain Service Network (BSN) and run on public city nodes. This enables blockchain framework developers to freely access the BSN through the BSN operation and maintenance management system.

[0183] To enable developers to publish and manage application chains across multiple blockchain underlying frameworks using a single private key and achieve interoperability between these application chains, step S42 may include: standardizing the key algorithms, access SDKs (Software Development Kits), Certificate Authority (CA) management, and certificates of the blockchain underlying frameworks according to preset underlying framework adaptation standards. This standardization process ensures that the standardized blockchain underlying frameworks possess a unified identity authentication service (i.e., different blockchain underlying frameworks, after standardization, have a unified identity authentication process). It should be noted that during the standardization process, each blockchain underlying framework retains its own unique smart contracts and consensus mechanisms.

[0184] In some examples, the default underlying framework adaptation standard may have the following characteristics: it has the characteristics of a permissioned blockchain, and the transaction execution and data ledger of multiple application chains running on the same node need to be securely isolated; the key algorithm must support the national cryptographic algorithm, and at the same time, it must also support other mainstream key algorithms; it can automate the creation, deployment, expansion, update, and removal of chain nodes, applications, smart contracts, etc., as well as the monitoring of running data; it has a complete ecosystem, with an active community, a large number of developers and application bases, comprehensive documentation and SDKs, and rich training, etc.

[0185] In the method provided by this invention, after the second server receives the underlying blockchain framework, it standardizes the underlying blockchain framework according to a preset underlying framework adaptation standard, so that the standardized underlying blockchain framework can be connected to the blockchain service network. This enables the underlying blockchain framework to be connected to the blockchain service network. At the same time, all underlying blockchain frameworks connected to the blockchain service network can be installed on public city nodes, giving developers more choices when deploying application chains. Furthermore, the installation of the underlying blockchain framework allows developers to use their familiar programming languages ​​to develop blockchain applications even without any blockchain development experience, reducing the difficulty of blockchain application development.

[0186] Based on the foregoing embodiments, a fifth embodiment of the method of the present invention is proposed. See also the embodiments described above. Figure 4 As shown, after step S13, the following steps are also included:

[0187] Step S51: The third server receives the deployment instructions issued by the user for the application chain to be deployed.

[0188] It should be noted that the third server includes a BaaS (Blockchain as a Service) platform. Subsequent steps on the third server can be executed based on the BaaS platform. A BaaS platform refers to an open blockchain platform that embeds a blockchain framework into a cloud computing platform, leveraging the deployment and management advantages of cloud service infrastructure to provide developers with a convenient, high-performance blockchain ecosystem and supporting services, supporting developers' business expansion and operational support.

[0189] BaaS platforms are built on blockchain service networks. In other words, BaaS platforms connect to blockchain service networks. This allows BaaS platforms to link to existing cloud service portals or developer portals within the blockchain service network, thereby providing BaaS platform customers with blockchain application development, deployment, and operation services based on the blockchain service network.

[0190] The application chain to be deployed is the application chain that the user wants to deploy.

[0191] The deployment instructions include selecting target cloud resources from all public city nodes of the blockchain service network. In other words, the target cloud resources are those selected by the user needing to deploy the application chain from all public city nodes of the blockchain service network through the BaaS platform.

[0192] In this embodiment of the invention, after the public city nodes are established, the third server can obtain all the public city nodes in the blockchain service network through the blockchain service network and provide them to the platform user. When the platform user needs to deploy an application chain, he / she can view the cloud resources of all the public city nodes in the blockchain service network on the BaaS platform and make a selection. The third server receives the deployment instructions issued by the user for the application chain to be deployed.

[0193] It should be noted that in some cases, the use of cloud resources requires payment. The BaaS platform can also provide the prices of cloud resources in various public city nodes. Platform users can view the prices of cloud resources in all public city nodes of the blockchain service network, select cloud resources, and make a purchase. Only after purchasing can the application chain be deployed based on the cloud resources.

[0194] Step S52: The third server sends the deployment instructions to the second server.

[0195] In this embodiment of the invention, after receiving the deployment instruction issued by the user for the application chain to be deployed, the third server sends the deployment instruction to the second server, so that the second server can deploy the application chain to be deployed to the target cloud resource based on the deployment instruction.

[0196] Step S53: The second server deploys the application chain to be deployed to the target cloud resource based on the deployment instructions.

[0197] After receiving the deployment instructions from the third server, the second server deploys the application chain to the target cloud resource based on the instructions.

[0198] In some implementations, the target cloud resources may further include at least one target public city node selected from all public city nodes of the blockchain service network, and the number of ledger nodes of the target public city node. That is, after selecting at least one target public city node from all public city nodes of the blockchain service network, the user can also configure the number of ledger nodes to be allocated to the application chain to be deployed within each target public city node.

[0199] Deployment instructions can also include the smart contract of the application chain to be deployed, as well as information on the selection of the underlying blockchain framework. Users can develop smart contracts according to their actual needs and upload them to a third-party server through the BaaS platform. Users can also select the underlying blockchain framework of the application chain to be deployed from all the underlying blockchain frameworks installed on public city nodes on the BaaS platform, and the third-party server receives the selection information. In this way, the complexity of the pre-built chaincode mechanism in the underlying blockchain framework is hidden from the user, enabling users with no blockchain development experience and no knowledge of blockchain programming languages ​​to enter the blockchain service network and deploy application chains using only their familiar programming languages ​​and runtime environments, making it easy for traditional business systems to have blockchain functionality.

[0200] In this approach, step S53 includes: the second server determining the underlying blockchain framework of the application chain to be deployed based on blockchain underlying framework selection information; deploying the application chain to be deployed on target public city nodes based on the smart contract of the application chain to be deployed and the underlying blockchain framework of the blockchain to be deployed; and configuring ledger nodes for the application chain to be deployed in each target public city node based on the number of ledger nodes. This allows users to upload smart contracts, select public city nodes, configure ledger node data, and configure the underlying blockchain framework on the BaaS platform according to their actual needs, providing users with diverse choices.

[0201] After being deployed on one or more public city nodes, each application chain processes transactions, communicates data, and stores data through a dedicated channel. Channels are completely isolated from each other, but data can be exchanged between channels if two application chains authorize each other. This mechanism guarantees absolute privacy for each application chain while providing sufficient flexibility for inter-chain business processing.

[0202] In some implementations, to improve security, the second server may perform a security check on the deployment instructions before step S53, and execute step S53 after the security check is passed.

[0203] In the method provided by this invention, a third server receives a deployment instruction from a user for an application chain to be deployed and sends the instruction to a second server. The deployment instruction includes a target cloud resource selected from all public city nodes of the blockchain service network. Based on the deployment instruction, the second server deploys the application chain to the target cloud resource, thereby achieving application chain deployment. In other words, when deploying an application chain, the user can select cloud resources from all public city nodes in the blockchain service network. Compared to purchasing a separate cloud server for application chain deployment, where the cloud resources are too large and lead to resource waste, this invention allows the user to select cloud resources from public city nodes as needed, enabling the purchase of smaller cloud resources, thus fully utilizing resources and avoiding waste. Furthermore, deploying the application chain based on resources from public city nodes in the blockchain service network eliminates the need to develop a separate blockchain operating environment using a cloud server, reducing the deployment difficulty of the application chain, facilitating effective supervision, further saving development, deployment, operation, interoperability, and supervision costs, and improving data accuracy, security, and production efficiency.

[0204] Based on the foregoing embodiments, a sixth embodiment of the method of the present invention is proposed. See also the embodiments described above. Figure 5 As shown, after step S53, the following may also be included:

[0205] Step S61: The third server receives the application chain processing request issued by the user through the business system.

[0206] It should be noted that after the application chain is deployed, a corresponding business system will be provided, through which users can perform corresponding processing on the application chain. In this embodiment of the invention, the third server includes the business system.

[0207] An application chain processing request is a request used to process data on a target application chain. Multiple application chains are deployed within the blockchain service network, and the target application chain is the application chain corresponding to the application chain processing request. Application chain processing requests include, but are not limited to, at least one of the following: data upload requests and data query requests. It should be noted that a data upload request triggers the uploading of data to be uploaded to the target application chain; a data query request triggers the querying of data from the target application chain. The data to be uploaded can be transaction data, etc.

[0208] In this embodiment of the invention, when a user needs to process the application chain, they can log in to the business system and trigger an application chain processing request through the business system. The third server receives the application chain processing request issued by the user through the business system.

[0209] Step S62: The third server sends the application chain processing request to the corresponding fourth server.

[0210] The fourth server is the server that includes the destination public city node corresponding to the application chain processing request. The destination public city node is the public city node corresponding to the destination application chain. It should be noted that the destination application chain may be deployed on multiple public city nodes. The destination public city node can be any one of the multiple public city nodes corresponding to the destination application chain, or it can be the one closest to the terminal where the user issued the application chain processing request, or it can be a public city node selected by the user from the multiple public city nodes corresponding to the destination application chain.

[0211] After receiving the application chain processing request through the business system, the third server needs to send the application chain processing request to the corresponding fourth server so that the fourth server can process the target application chain based on the application chain processing request.

[0212] Step S63: The fourth server processes the request based on the application chain and processes the target application chain.

[0213] After receiving the application chain processing request sent by the third server, the public city node in the fourth server processes the target application chain based on the application chain processing request.

[0214] It should be understood that different application chains handle requests in different ways, and the specific handling method can be flexibly set according to actual needs.

[0215] It should be noted that if an application chain processing request involves processing data on the application chain, the request must be sent to the corresponding ledger node. Public city nodes can allocate ledger nodes to application chains based on their processing frequency. For example, if an application chain has a high processing frequency, a high-performance ledger node can be configured for it; if its processing frequency is low, multiple application chains can share a single ledger node. The determination of whether an application chain's processing frequency is high can be based on a preset frequency threshold. For instance, if an application chain's processing frequency exceeds the preset threshold, it is considered to have a high processing frequency.

[0216] In some implementations, the public city node may include an Nginx load balancing cluster. After receiving an application chain processing request, the public city node sends it to the Nginx load balancing cluster. Based on the operating status of each node gateway in the public city node, the Nginx load balancing cluster sends the application chain processing request to the corresponding node gateway, and then the node gateway processes the application chain processing request.

[0217] Nginx is a high-performance HTTP (Hypertext Transfer Protocol) and reverse proxy web (World Wide Web) server.

[0218] In some implementations, after step S62, the processing result can be sent to the business system of a third server so that the user is aware of the processing result. For example, if the application chain processing request is a data upload request, after successful data upload, a data upload success notification is sent to the BaaS business system; after data upload failure, a data upload failure notification is sent to the BaaS platform's business system.

[0219] In the method provided by this embodiment of the invention, the third server receives the application chain processing request issued by the user through the business system via the BaaS platform, and sends the application chain processing request to the fourth server. The fourth server processes the target application chain based on the application chain processing request, thereby realizing the user's control over the application chain.

[0220] Based on the foregoing embodiments, a seventh embodiment of the method of the present invention is proposed. It should be understood that different application chain processing requests have different processing methods. In this embodiment of the present invention, the application chain processing request is a data upload request, and step S62 includes:

[0221] Step S621: The fourth server uploads the data to be uploaded to the target application chain based on the data upload request.

[0222] The data upload request includes the data to be uploaded to the blockchain. After receiving the data upload request, the public city node can upload the data to be uploaded to the target application blockchain based on the data upload request.

[0223] It should be noted that the application chains deployed on public city nodes include public chains and permissioned chains. A public chain is a blockchain in which anyone in the world can access the system at any time to read data, send verifiable transactions, and compete for ledger recording; a permissioned chain is a blockchain in which each node participating in the blockchain system is authorized, and unauthorized nodes cannot access the system.

[0224] Different types of application chains have different processing flows.

[0225] If the target application chain is a public chain, step S621 includes:

[0226] Step 1: If the target application chain is a public chain, the fourth server sends the data upload request to the public chain gateway.

[0227] It should be understood that public city nodes include public blockchain gateways and permissioned blockchain gateways. Public blockchain gateways process requests related to public blockchains, while permissioned blockchain gateways process requests related to permissioned blockchains.

[0228] If the target application chain for the data upload request is a public chain, the public city node will send the data upload request to the public chain gateway.

[0229] Step 2: The fourth server sends the data upload request to the public blockchain ledger node through the public blockchain gateway.

[0230] It should be noted that public city nodes include public blockchain ledger nodes, which are used to manage the data on the public blockchain.

[0231] After the target public city node on the fourth server sends the data upload request to the public blockchain gateway, the public blockchain gateway sends the data upload request to the public blockchain ledger node.

[0232] In some implementations, since the use of public blockchains requires payment, after receiving a data upload request, the public blockchain gateway can obtain the data package data purchased by the user corresponding to the data upload request, and determine whether the user has the right to use the service based on the data package data purchased by the user. If so, then proceed to step two.

[0233] The specific method for obtaining the user's purchased package data corresponding to the data upload request can be flexibly configured according to actual needs. For example, in some examples, the public city node also includes a system permission chain, a permissioned chain ledger node, an authentication service, and a message queue. The BSN operation and maintenance management system in the second server includes all user-purchased package data and the system permission chain. The system gateway of the BSN operation and maintenance management system can upload all user-purchased package data to the system permission chain, and the system permission chain of the public city node is synchronized with all user-purchased package data. The permissioned chain ledger node synchronizes package data through the system permission chain. The authentication service can periodically obtain package data from the system permission chain and add the package data to the message queue. The public chain gateway can periodically obtain package data from the message queue. In this way, when a data upload request is received, the public chain gateway can determine whether the user corresponding to the data upload request has the necessary permissions based on the package data. If so, step two is then executed.

[0234] Step 3: The fourth server sends the data upload request to the public blockchain network ledger node through the public blockchain ledger node, so that the data to be uploaded can be uploaded to the target application chain through the public blockchain network ledger node.

[0235] It should be noted that the blockchain service network includes public blockchain ledger nodes. After receiving a data upload request, the public blockchain ledger node of the public city node can send the request to the public blockchain ledger node via the internet. The public blockchain ledger node then uploads the data to the target application chain based on the data upload request.

[0236] If the target application chain is a permissioned chain, step S621 includes:

[0237] Step 1: If the target application chain is a permissioned chain, the fourth server will send the data request to the permissioned chain gateway.

[0238] Upon receiving a data upload request, if the target application chain of the data upload request is a permissioned chain, the target public city node in the fourth server will send the data request to the permissioned chain gateway.

[0239] Step 2: The fourth server verifies the data upload request through the permissioned chain gateway.

[0240] After receiving a data upload request, the permissioned blockchain gateway can verify the data upload request.

[0241] It should be understood that the data upload request includes user signature data, and the permissioned blockchain gateway can verify whether the user has the necessary permissions based on the user signature data.

[0242] The specific verification method can be flexibly set according to actual needs.

[0243] In some implementations, the system permission chain stores the user's application access key (public key) and the application's permission configuration. After receiving a data upload request, the permission chain gateway can send the data upload request to the authentication service for authentication. The authentication service can verify the user signature data in the data upload request based on the user's application access key (public key) and the application's permission configuration obtained from the system permission chain to determine whether the user has the permission to access the target application chain, and return the verification result to the permission chain gateway.

[0244] Before sending the data request to the authentication service for authentication, the permissioned blockchain gateway can also cache the TPS of the user corresponding to the data upload request to reserve the required TPS before sending the data upload request to the authentication service for authentication.

[0245] Before sending the data request to the authentication service for authentication, the permission chain gateway can also cache the user's permission information corresponding to the data on-chain request to the caching service to save user operation records.

[0246] Step 3: After successful verification, the fourth server routes the data upload request to the corresponding target blockchain underlying framework microservice through the permissioned blockchain gateway.

[0247] It should be noted that in this embodiment of the invention, different underlying blockchain frameworks are installed on the public city nodes, and the underlying blockchain framework microservices are different for each underlying blockchain framework.

[0248] Among them, the underlying blockchain framework microservices of the target application chain are the underlying blockchain framework services.

[0249] After the permissioned blockchain gateway verifies the data upload request, it can send the data upload request to the target blockchain underlying framework microservice.

[0250] Different key algorithms result in different underlying blockchain frameworks, and consequently, different microservices within those frameworks. A permissioned blockchain gateway can obtain the key algorithm of the target application chain based on the data upload request, determine the target blockchain's underlying framework microservice based on the key algorithm, and thus route the data upload request to that microservice.

[0251] Step 4: The fourth server verifies the data upload request through the underlying blockchain framework microservice.

[0252] The purpose is to verify the data upload request after the underlying blockchain framework microservice receives the data upload request.

[0253] The specific verification method can be flexibly configured according to actual needs. In some examples, the CA management module of the public city node can receive user registrations and register the user identity certificates and keys required by the ledger node. After registration, these can be sent to the ledger node. The target blockchain underlying framework microservice can send data upload requests to the CA management module. The CA management module verifies the validity of the user identity certificates in the data upload request. After successful verification, it signs the data to be uploaded to the chain and sends the signed data to the target blockchain underlying framework microservice, so that the target blockchain underlying framework microservice can upload the signed data to the target application chain through the corresponding ledger node.

[0254] Step 5: After successful verification, the fourth server uploads the data to be added to the target application chain through the ledger node corresponding to the microservice of the target blockchain underlying framework.

[0255] In this embodiment of the invention, corresponding ledger nodes are configured for different underlying blockchain frameworks.

[0256] After successful verification, the underlying microservice of the target blockchain framework sends the data upload request to the corresponding ledger node, so that the ledger node can upload the data to be uploaded to the target application chain, thereby completing the data upload.

[0257] In the method provided by this embodiment of the invention, a third server receives a data upload request issued by a user through a business system and sends the data upload request to a fourth server, wherein the fourth server includes a destination public city node corresponding to the data upload request; based on the data upload request, the fourth server uploads the data to be uploaded to the destination application chain corresponding to the data upload request, thereby realizing the data upload.

[0258] Based on the foregoing embodiments, an eighth embodiment of the method of the present invention is proposed. It should be understood that different application chains process requests with different processing methods. In this embodiment of the present invention, the application chain processing request is a data query request, and step S62 includes:

[0259] Step S622: The fourth server queries data from the target application chain based on the data query request to obtain the target data.

[0260] After receiving the data query request, the fourth server queries the data from the target application chain through the target public city node to obtain the target data.

[0261] Step S623: The fourth server sends the destination data to the third server.

[0262] The fourth server sends the target data to the third server so that the third server can display the target data for the user to view.

[0263] Following step S623, the process also includes step S624: The third server displays the target data.

[0264] After receiving the target data, the third server can display the target data through the BaaS platform. In some implementations, if the data query request is triggered by a user through a business system, the third server can send the target data to the business system so that the business system can display the target data, thereby allowing the user to obtain the queried data through the business system.

[0265] It should be noted that the query process differs for different types of application chains.

[0266] If the target application chain is a public chain, step S622 includes:

[0267] Step 1) If the target application chain is a public chain, the fourth server will send the data query request to the public chain gateway.

[0268] If the target application chain of the data query request is a public chain, the public city node will send the data query request to the public chain gateway.

[0269] Step 2) The fourth server sends the data query request to the public blockchain ledger node through the public blockchain gateway.

[0270] After the public city node sends the data query request to the public blockchain gateway, the public blockchain gateway sends the data query request to the public blockchain ledger node.

[0271] In some implementations, since the use of a public blockchain requires payment, after receiving a data query request, the public blockchain gateway can obtain the data on the user's purchased service plan corresponding to the data query request, and determine whether the user has the right to use the service based on the purchased service plan data. If so, then proceed to step 2).

[0272] The specific method for obtaining the user's purchased package data corresponding to the data query request can be found in the aforementioned method for obtaining the user's purchased package data corresponding to the data upload request, and will not be repeated here.

[0273] Step 3) The fourth server sends the data query request to the public blockchain network ledger node through the public blockchain ledger node, so that the public blockchain network ledger node can query the data from the target application chain to obtain the target data.

[0274] It should be noted that after receiving a data query request, the public blockchain ledger node sends it to the public blockchain network ledger node via the Internet, so that the public blockchain network ledger node can query the data from the target application chain to obtain the target data.

[0275] Step 4) The fourth server receives the destination data sent by the public blockchain network ledger node.

[0276] Public city nodes receive target data from public blockchain network ledger nodes.

[0277] In some implementations, the target data sent by the public blockchain ledger node can be received through the public blockchain ledger node of the public city node.

[0278] Step S623 includes: the fourth server sending the target data to the third server through the public blockchain gateway.

[0279] After receiving the target data, the public blockchain ledger node can send the target data to the public blockchain gateway, which then sends the target data to the third-party server.

[0280] If the target application chain is a permissioned chain, step S622 includes:

[0281] Step (1): If the target application chain is a permissioned chain, the fourth server sends the data query request to the permissioned chain gateway.

[0282] If the target application chain is a permissioned chain, the target public city node will send the data query request to the permissioned chain gateway.

[0283] Step (2): The fourth server verifies the data query request through the permissioned chain gateway.

[0284] The data query request includes user signature data. After receiving the data query request, the permissioned blockchain gateway can verify the data query request based on the user signature data. For specific verification methods, please refer to the aforementioned method for permissioned blockchain gateways to verify data upload requests, which will not be repeated here.

[0285] Step (3): After the verification is successful, the fourth server routes the data query request to the corresponding target blockchain underlying framework microservice through the permissioned blockchain gateway.

[0286] After successful verification, the permissioned blockchain gateway routes the data query request to the corresponding target blockchain underlying framework microservice. For details, please refer to the aforementioned method of the permissioned blockchain gateway routing data upload requests to the corresponding target blockchain underlying framework microservice; it will not be repeated here.

[0287] Step (4): The fourth server verifies the data query request through the underlying blockchain framework microservice.

[0288] After receiving a data query request, the target blockchain underlying framework microservice verifies the request.
