[0032] In providing financial transaction services to clients, financial institutions use blockchain technology to create blockchain networks to enhance the security of financial transaction data generated during the process.

[0033] In one example, based on manual processing, the user inputs a script for the blockchain network creation process. At each step of the blockchain network creation process, the user needs to manually input the execution command to run the corresponding execution code and complete the creation of the blockchain network.

[0034] However, the above methods rely on manual input, which is cumbersome and reduces the efficiency of creating blockchain networks.

[0035] The method, apparatus, device, and storage medium for creating a blockchain network provided in this application are intended to solve the aforementioned technical problems of the prior art.

[0036] It should be noted that the financial transaction data (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0037] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0038] Figure 1 A flowchart illustrating a method for creating a blockchain network provided in this application embodiment is shown below. Figure 1 As shown, the method includes:

[0039] S101. Receive organization information and consortium information input by the user; wherein, the organization information is the information of network nodes in the blockchain network, and the network nodes are used to process financial transaction data; the consortium information represents the information of the consortium chain in the blockchain network; the consortium chain is used to store the financial transaction data processed by the network nodes.

[0040] For example, the execution subject of this embodiment can be an electronic device. First, Figure 2 This is a schematic diagram of the structure of a blockchain network creation system provided in an embodiment of this application, such as... Figure 2As shown, the blockchain network creation system deployed in the electronic device as a service (BaaS) includes a visual interface layer, a basic management layer, and a blockchain underlying layer. Users transmit automated blockchain network creation instructions to the basic management layer through the visual interface. The basic management layer service initializes the process task sequence, sequentially passing the instructions to the node agent service at the blockchain underlying layer. The blockchain underlying layer consists of the node agent service, Docker container technology service, transaction peer nodes, and orderer nodes. The node agent service performs relevant operations according to the instructions. To create a blockchain network, users input information through a user-friendly interface provided by the visualization layer. This visualization interface provides visual configuration entry points for servers, organizations, nodes, consortia, and organization members. It receives user-inputted information about network nodes (organizational information) and consortium blockchains (consortium information). Organizational information includes the network node name (organization name, abbreviation, domain name), number of peer nodes, and number of user device users (UESRs). Consortium information includes the consortium name, abbreviation, domain name, number of ordering nodes (orderer nodes), designated leader organization (main network node), and the user-preset Internet Protocol (IP) address for each orderer node. Furthermore, each consortium blockchain corresponding to the user-inputted information is used to store the financial transaction data processed by the network nodes.

[0041] S102. Establish the mapping relationship between the consortium chain in the consortium information and the network nodes in the organization information.

[0042] For example, based on the visual interface, for each consortium chain in the consortium information, in response to the user's input operation on the visual interface, the organization determined by the user, i.e. the network node, is selected from the organization information created by the user and added to the consortium chain, thereby establishing a mapping relationship between each consortium chain and each network node in the organization information.

[0043] S103. In response to the user-inputted creation instruction, determine the instruction information set; wherein, the creation instruction is used to instruct the creation of a blockchain network; the instruction information set includes at least one instruction information; the instruction information represents the execution code of the network creation process; the instruction information has an execution sequence number, which is the execution sequence number of the execution code represented by the instruction information.

[0044] For example, the basic management layer provides consortium blockchain management functions such as server management, organization management, node management, alliance management, member management, and network creation / publishing. After adding alliance members, users can initiate the network creation process through a visual interface. That is, users input creation instructions through the visual interface to instruct the creation of a blockchain network. Based on the visual interface, the system responds to the user's input creation instructions and sends the instructions to the basic management layer. After receiving the network creation instructions, the basic management layer initializes the network creation process and feeds back to the visual interface layer. Users can see the execution process of the network creation process initialization in the visual interface layer. After initializing the network creation process, the basic management layer collects a set of instruction information from the database. This set of instruction information includes at least one instruction, which represents the execution code of the network creation process. The instruction has an execution sequence number, which is the execution sequence number of the execution code represented by the instruction, such as the server sequence of the instruction execution, instruction parameters, and process execution sequence order.

[0045] S104. Based on a visual interface, a blockchain network is created according to the instruction information set, organization information, and alliance information; wherein, the blockchain network is used to process financial transaction data.

[0046] For example, the basic management layer, according to the process execution sequence in the instruction information set, sequentially sends network creation tasks to the node agent services of each consortium blockchain at the underlying blockchain layer. The node agent services provide a set of consortium blockchain network deployment service interface methods, integrating key technologies such as Java, scripts, commands, Docker container technology, and Fabric ontology. Upon receiving the blockchain network creation instructions from the basic management layer, the node agent services execute the blockchain network creation process on their local servers based on the organization and consortium information. Once the execution process is complete, the blockchain network is created. During the automated execution of blockchain network creation, a visual interface layer allows for efficient and intuitive completion of the creation process.

[0047] This embodiment provides a method for creating a blockchain network. Based on a visual interface, it automatically executes each network creation task corresponding to the instruction information set, which can realize the automation of consortium blockchain network deployment and provide a user-friendly interactive interface to intuitively display the execution process of blockchain network creation.

[0048] Figure 3 A flowchart illustrating another method for creating a blockchain network provided in this application embodiment is shown below. Figure 3 As shown, the method includes:

[0049] S201. Receive organization information and consortium information input by the user; wherein, the organization information is the information of network nodes in the blockchain network, and the network nodes are used to process financial transaction data; the consortium information represents the information of the consortium chain in the blockchain network; the consortium chain includes at least one network node, and the network nodes in the consortium chain communicate with each other.

[0050] For example, this step can be referred to step 101, and will not be repeated here.

[0051] S202. Determine the set of node information corresponding to the organization information; wherein, the set of node information includes the node information corresponding to each network node in the organization information, and the node information includes the server address, port number and anchor node identifier of the network node.

[0052] For example, through a visual interface, the network nodes such as peer nodes in the organization information that has been initialized and created are mapped to their corresponding server IPs, and a port number is assigned to each peer node and an anchor node flag is set, thus obtaining the node information corresponding to each network node.

[0053] S203. Store the organization information, alliance information, and node information in a preset database.

[0054] For example, after creating organization information and alliance information through a visual interface, the created organization information and alliance information are stored in a preset database through the basic management layer service interface.

[0055] S204. In response to a query command input by the user, determine network nodes that meet the preset admission criteria of the consortium blockchain from the organization information, and designate them as target network nodes of the consortium blockchain; wherein, the query command is used to instruct the query network node, and the query command includes the preset admission criteria of the consortium blockchain in the consortium information.

[0056] For example, for each consortium blockchain in the consortium information, the user enters a query command through a visual interface, specifying the network nodes that meet the predefined admission criteria for that consortium blockchain. Based on the visual interface, after receiving the user's query command for each consortium blockchain, the system determines the network nodes that meet the predefined admission criteria from the organization information, which are then identified as the target network nodes for that consortium blockchain. This process retrieves a list of organizations that meet the consortium joining criteria.

[0057] S205. Establish a mapping relationship between the alliance chain in the alliance information and the target network node in the organization information.

[0058] For example, through a visual interface, users can select target network nodes from the organization information for each consortium chain to join that consortium chain, establish a mapping relationship between each consortium chain in the consortium information and the organization, i.e., the target network node of each consortium chain, and store the collected information in the database through the basic management layer service interface.

[0059] In one example, the consortium blockchain has consortium blockchain nodes, which are used to sort financial transaction data processed by network nodes in the consortium blockchain; step S205 includes: establishing a mapping relationship between the consortium blockchain nodes and the target network nodes of the consortium blockchain.

[0060] For example, each consortium blockchain created based on the visual interface has a corresponding consortium blockchain node, which is used to sort the financial transaction data processed by the corresponding network node in the consortium blockchain. Through the visual interface, users can select the target network node in the organization information to join the consortium blockchain for each consortium blockchain, and establish a mapping relationship between the consortium blockchain node of each consortium blockchain in the consortium information and the target network node corresponding to each consortium blockchain in the organization information. The collected information is stored in the database through the basic management layer service interface.

[0061] S206. In response to the user-inputted creation instruction, determine an instruction information set; wherein, the creation instruction is used to instruct the creation of a blockchain network; the instruction information set includes at least one instruction information; the instruction information represents the execution code of the network creation process; the instruction information has an execution sequence number, which is the execution sequence number of the execution code represented by the instruction information.

[0062] For example, this step can be referred to as step 103, and will not be repeated here.

[0063] S207. Based on the organization information, generate a certificate information set corresponding to the organization information; wherein, the certificate information set includes certificate information corresponding to each network node in the organization information, and the certificate information represents the identity of the network node in the consortium blockchain; and send the certificate information to the server of the consortium blockchain corresponding to the certificate information.

[0064] For example, based on the instruction information for blockchain network creation received by the basic management layer, the basic management layer collects user-configured consortium organization member information (i.e., organization information) from the database, calls the `cryptogen generate` command to process the organization information, and creates certificates for the organization members. These certificates represent the identity of each network node in the organization information, thus identifying the network node's identity within the consortium blockchain. After completing the organization member certificates, the basic management layer, according to the consortium organization plan collected from the database, calls the blockchain's underlying node proxy service's distribution interface to distribute the organization member certificate files to the corresponding servers designated by each consortium organization, based on the relationship between the consortium blockchain and each network node in the organization information.

[0065] S208. Genesis block file of consortium blockchain is generated according to the creation instructions and consortium information in the instruction information.

[0066] In one example, the instruction set includes a genesis block creation instruction, a network configuration instruction, and a network startup instruction; the genesis block creation instruction is used to instruct the creation of a genesis block file for the consortium blockchain, which represents the initially created network block in the consortium blockchain; the network configuration instruction is used to instruct the configuration of the network for the consortium blockchain; and the network startup instruction is used to instruct the startup of the network configured for the consortium blockchain.

[0067] For example, the node agent service based on the underlying blockchain receives instruction information on blockchain network creation sent by the basic management layer, including instructions to create genesis block, network configuration, and network start; the instructions to create genesis block are used to instruct the creation of genesis block file for the consortium blockchain, the genesis block file representing the initially created network block in the consortium blockchain; the instructions to configure the network for the consortium blockchain are used to instruct the network to be started; and the instructions to start the network are used to instruct the network configured for the consortium blockchain to be started.

[0068] For example, after the basic management layer completes the issuance of organization certificates, according to the information of each consortium chain in the consortium information stored in the database, the blockchain node agent service receives the instruction to create a genesis block, calls the blockchain underlying node agent service to create a genesis block interface, calls preset commands, processes the information of each consortium chain in the consortium information, and generates a genesis.block file, that is, the genesis block file of each consortium chain.

[0069] In one example, step S208 includes the following steps:

[0070] The first step of step S208 is to determine the leader node of each consortium chain in the consortium information according to the creation of the genesis block instruction; wherein, the leader node is the network node in the consortium chain used to process other network nodes.

[0071] The second step of step S208 is to generate a configuration file for the consortium blockchain based on the consortium blockchain's leader node; wherein, the configuration file is the configuration file for the consortium blockchain's channel transactions.

[0072] The third step of step S208 is to generate the genesis block file of the consortium blockchain according to the configuration file of the consortium blockchain.

[0073] For example, after the basic management layer completes the issuance of organizational certificates, it calls the blockchain underlying node proxy service to create a genesis block interface. After receiving the genesis block creation instruction, the blockchain node proxy service, according to the consortium information collected in the database, determines the network node in each consortium chain that is used to process other network nodes in that consortium chain, which is the leader node. According to the proxy service's genesis block creation interface, it processes the information of the leader node of the consortium chain, generates a configuration file for the channel transactions of that consortium chain, such as the configtx.yam file, and calls the configtxgen-profile command to process the configuration file, such as the configtx.yam file, to generate a genesis block file, such as the genesis.block file.

[0074] S209. Based on the network configuration instructions and organization information in the instruction information, generate the system file corresponding to the organization information; wherein, the system file includes the consortium chain nodes of the consortium chain, the network nodes in the consortium chain, and the mapping relationship between the servers to which the consortium chain belongs.

[0075] For example, after the basic management layer completes the creation of the genesis block, the database collects information on the network nodes corresponding to each consortium chain in the organization information, calls the network configuration interface of the blockchain underlying node proxy service, and after receiving the network configuration instruction, the blockchain underlying node proxy service generates a system file corresponding to the organization information. The system file includes the consortium chain nodes of each consortium chain, the network nodes in each consortium chain, and the mapping relationship between the servers to which each consortium chain belongs. For example, the mapping relationship between the domain names of network nodes such as peer nodes and orderer nodes in each consortium chain and the server IPs is written into the hosts file of the local server.

[0076] S210. Based on the network startup instruction and organization information in the instruction information, generate and execute the startup file set corresponding to the organization information to obtain the blockchain network; wherein, the startup file set includes the running code corresponding to each network node in the organization information, and the running code of the consortium blockchain node corresponding to each network node in the organization information.

[0077] For example, after the basic management layer completes the network configuration, the underlying blockchain node agent service receives the network start instruction and calls the network start interface of the underlying blockchain node agent service. It processes the organization information and consortium information stored in the preset database to generate a set of startup files. These files include the running code corresponding to each network node in the organization information and the running code of the consortium chain node corresponding to each network node in the organization information, such as the Docker startup files for each orderer node and each peer node. Then, using the docker-compose command, it executes the network startup configured for each consortium chain in the startup file set in sequence and synchronizes the execution process to the visualization interface layer. Based on the visualization interface, it monitors the execution process of the blockchain network creation process and displays the results visually.

[0078] S211. Based on a visual interface, display the execution information set corresponding to the instruction information set, and store the execution information set in a preset database; wherein, the execution information set includes the execution information corresponding to each instruction information in the instruction information set, and the execution information indicates whether the execution code represented by the instruction information has been executed successfully.

[0079] For example, during the automated execution of blockchain network creation, users can call the basic management layer task query interface through task polling to listen to the execution process of the blockchain network creation process. This allows them to obtain the execution information corresponding to each instruction in the instruction information set, indicating whether the execution code represented by the instruction information has been successfully executed. The results represented by each execution information are then visualized, and the results represented by each execution information are recorded in a local preset database such as an SQLite database. In this way, the blockchain network creation process can be completed efficiently.

[0080] In this embodiment, based on the above embodiments, on the one hand, the creation process of the blockchain network is displayed intuitively through visualization; on the other hand, the blockchain network creation process is automatically executed based on the instruction information set, which reduces the implementation difficulty and complexity of creating a visualized blockchain network and improves the implementation efficiency of creating a blockchain network.
