[0067] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments made by ordinary technicians in this field under the enlightenment of the embodiments belong to the scope of protection of the present application.

[0068] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0069] First, the terms involved in this application are explained:

[0070] Blockchain: Blockchain is a distributed ledger that is distributed on computer nodes and records all transactions that occur on the network. On-chain means recording transfer records, orders, data distribution tables and other information that needs to be on-chain on blocks. Blocks are storage units that record all the communication information of each block node within a certain period of time. Each block is linked through random hashing (also known as hash algorithm). The next block contains the hash value of the previous block. As the information exchange expands, one block is connected to another, and the result is called blockchain.

[0071] Blockchain as a Service (BaaS) platform: refers to an open blockchain platform that embeds the blockchain framework into a cloud computing platform, takes advantage of the deployment and management of cloud service infrastructure, provides developers with a convenient and high-performance blockchain ecological environment and ecological supporting services, and supports developers' business expansion and operation support. The BaaS platform combines and encapsulates blockchain technology and modularizes it into commonly used functions such as host management, blockchain network management, channel management, smart contracts, blockchain browser management, blockchain monitoring, certificate management, and user management. When users need to store and query on the blockchain, they only need to connect these functions through interfaces such as the Application Programming Interface (API) and the Software Development Kit (SDK), and they can directly use the blockchain BaaS platform to store and query smart contracts on the blockchain.

[0072] Virtualized BaaS platform: Based on software definition, the Baas platforms of various types of alliance chains are virtualized and managed, and finally a platform with unified external service capabilities is provided.

[0073] Terminal device: refers to a device that inputs programs and data into a computer or receives computer output processing results via communication facilities. Terminal devices are usually set up in a convenient place where communication facilities can be used to connect to a remote computer for work. It is mainly composed of a communication interface control device and a dedicated or selected input and output device. Terminal devices include but are not limited to devices that communicate via a data connection / network and / or via a wireless interface, such as communication devices for cellular networks and wireless local area networks (WLAN). Terminal devices are devices with sending, receiving, and input functions, and have a display. It can be a desktop computer or other intelligent terminals such as a laptop computer. The embodiments of the present application do not limit the specific form of the terminal device, which can be determined according to actual needs.

[0074] Blockchains are mainly divided into public chains, alliance chains, and private chains. Among them, there are many heterogeneous types of alliance chains in the prior art. For each alliance chain, a corresponding BaaS platform is set up, and users can use the corresponding BaaS platform to store and query smart contracts on the alliance chain. That is, users can only store and query smart contracts on the alliance chain through the BaaS platform corresponding to a certain type of alliance chain according to the usage rules of the alliance chain. When the user needs to use another type of alliance chain, the corresponding BaaS platform needs to be replaced, and the usage rules of each type of alliance chain are different. Therefore, when the user changes to another type of alliance chain, the usage rules of the alliance chain need to be replaced, which makes the user's use of the alliance chain more cumbersome.

[0075] In view of the problems existing in the prior art, the inventors found in the process of studying the on-chain storage and query of smart contracts on the blockchain through the blockchain BaaS platform that if there is a virtualized BaaS platform that can be connected with various types of alliance chains to realize the call of various types of alliance chains, it can solve the technical problem that the user's use of the alliance chain is relatively cumbersome. That is, through the virtualized BaaS platform, centralized control and unified services for various types of alliance chains can be achieved. No matter which blockchain meets the user's usage needs, it can be connected to the corresponding blockchain through the virtualized BaaS platform using the same rules, making the user's use of the alliance chain process simpler and more convenient. Based on the above invention concept, the blockchain-based data processing solution in this application is designed.

[0076] The blockchain-based data processing solution of this application is described in detail below.

[0077] Figure 1 The following is a schematic diagram of an application scenario of the blockchain-based data processing method provided in this application, such as Figure 1As shown, the application scenario may include: terminal device 101, virtualized BaaS platform 102, and BaaS platforms corresponding to various types of alliance chains ( Figure 1 Three BaaS platforms are shown, namely BaaS platform 103, BaaS platform 104, BaaS platform 105, and at least one blockchain ( Figure 1 Four blockchains are shown, namely blockchain 106, blockchain 107, blockchain 108, and blockchain 109. Among them, BaaS platform 103, BaaS platform 104, and BaaS platform 105 are BaaS platforms corresponding to three different types of blockchains; BaaS platform 103 can be any one of Spark Chain BaaS platform, Changan Chain BaaS platform, Super Chain BaaS platform, and Unicom Chain BaaS platform, BaaS platform 104 can be any one of Spark Chain BaaS platform, Changan Chain BaaS platform, Super Chain BaaS platform, and Unicom Chain BaaS platform, and BaaS platform 105 can be any one of Spark Chain BaaS platform, Changan Chain BaaS platform, Super Chain BaaS platform, and Unicom Chain BaaS platform. Exemplarily, BaaS platform 103 can be Spark Chain BaaS platform, BaaS platform 104 can be Unicom Chain BaaS platform, and BaaS platform 105 can be Changan Chain BaaS platform. Among them, blockchain 106 and blockchain 107 may be blockchains corresponding to BaaS platform 103 , blockchain 108 may be blockchain corresponding to BaaS platform 104 , and blockchain 109 may be blockchain corresponding to BaaS platform 105 .

[0078] For example, in Figure 1 In the application scenario shown, when the user wants to store evidence on the blockchain, a request message containing the on-chain requirement information is sent to the virtualized BaaS platform 102 through the terminal device 101. The virtualized BaaS platform 102 obtains the blockchain 106 that matches the on-chain requirement information according to the request information sent by the terminal device 101, and then the virtualized BaaS platform 102 sends a feedback message including the first identifier of the first blockchain to the terminal device 101. After receiving the feedback message sent by the virtualized BaaS platform 102, the terminal device 101 generates an on-chain request according to the information to be on-chain input by the user and the first identifier, and sends the on-chain request to the virtualized BaaS platform 102.

[0079] The virtualized BaaS platform 102 receives the on-chain request sent by the terminal device 101, and determines the BaaS platform 103 corresponding to the blockchain 106 based on the first identifier. The virtualized BaaS platform 103 forwards the on-chain request to the BaaS platform 103.

[0080] The BaaS platform 103 receives the on-chain request forwarded by the virtualized BaaS platform 102 and performs an on-chain operation, that is, writes the information to be on-chain into the blockchain 106 .

[0081] Based on the above process, when users have any on-chain needs, they can directly send request information including on-chain demand information to the virtualized BaaS platform through the terminal device. After the virtualized BaaS platform obtains the target blockchain that matches the on-chain demand information, the terminal device sends an on-chain request including the target blockchain to the virtualized BaaS platform to complete the on-chain operation. In other words, when users use any type of alliance chain, they are connected to the virtualized BaaS platform without changing the BaaS platform; and because users use any type of alliance chain to connect to the virtualized BaaS platform, users use any type of alliance chain. The same rules are used, making the process of users using alliance chains simpler and more convenient, and improving the user experience.

[0082] It should be noted that Figure 1 This is only a schematic diagram of an application scenario provided by the embodiment of the present application. Figure 1 The actual form of the various devices included in the Figure 1 The interaction mode between devices is limited, and in the specific application of the solution, it can be set according to actual needs.

[0083] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0084] Figure 2 This is an interactive diagram of the first embodiment of the data processing method based on blockchain provided by this application. Figure 2 , the data processing method based on blockchain specifically includes the following steps:

[0085] Step S201: The terminal device receives the uplink demand information input by the user.

[0086] When a user needs to store evidence on the blockchain, the user enters the on-chain requirement information on the terminal device, and the terminal device generates a request message based on the on-chain requirement information entered by the user.

[0087] In a specific implementation, the terminal device displays a visualization interface, and multiple selectable parameter information is displayed in the visualization interface, and the multiple selectable parameter information belongs to the parameter information in the parameter information set. The parameter information in the parameter information set can be divided into different categories. For example, the number of block transactions and the required capacity of the block can be a type of parameter information, and the number of consensus nodes and consensus strategy of the blockchain can be a type of parameter information. The user determines the required parameters according to the chain requirements, and the terminal device can obtain the chain requirement information according to the parameter information selected by the user. Among them, the multiple selectable parameter information may include at least two of the following:

[0088] Cryptographic algorithm: The cryptographic algorithm of the blockchain network, which can be the standard version or the national secret version;

[0089] Consensus strategy: It can be RAFT strategy or solo strategy; RAFT stands for Replicated And Fault Tolerant.

[0090] The number of consensus nodes of the blockchain: the default value is 3, and it can also be 5. The embodiment of the present application does not specifically limit the number of consensus nodes, and it can be selected according to actual conditions;

[0091] The blockchain ledger storage method can be CouchDB or LevelDB. CouchDB is short for Cluster of unreliable commodity hardware Data Base, and LevelDB is short for Level Data Base.

[0092] The number of nodes in the blockchain: the number of nodes (peers) corresponding to the business organization can be 3 or 5. The embodiment of the present application does not specifically limit the number of nodes and can be selected according to actual conditions.

[0093] Supported versions: Distributed ledger platform versions supported by blockchain;

[0094] Deployment cluster: This can be one of the existing clusters or a new cluster.

[0095] Whether the secure transmission protocol (Transport Layer Security, TLS for short) is enabled during the chain upload process;

[0096] Whether the digital certificate authentication system (Certification Authority, CA for short) is enabled during the chaining process;

[0097] Block generation time: can be 2s or 4s. The embodiment of the present application does not specifically limit the block generation time, and can be selected according to actual conditions;

[0098] Number of block transactions: The maximum number of transactions that can be stored in a block can be 100 or 200. The embodiment of the present application does not specifically limit the number of block transactions, and the number can be selected according to actual conditions;

[0099] Block capacity required: The maximum capacity of a block that can store transactions. The number of transactions in a block is related to the required capacity of the block. For example, a transaction is about 250 bytes, and 1M can accommodate 4,000 transactions. The required capacity of a block can be 99MB or 50MB. The embodiment of this application does not specifically limit the required capacity of a block, and it can be selected according to actual conditions.

[0100] Optionally, the visualization interface may also include a "Finish" icon. When the user has selected the required parameters, the user clicks the "Finish" icon. The terminal device obtains the uplink requirement information according to the parameter information selected by the user, and generates a request message based on the uplink requirement information.

[0101] In another specific implementation, the terminal device is provided with a physical button. After the user has selected the required parameters, the physical button is operated. The terminal device obtains the uplink demand information according to the parameter information selected by the user, and generates a request message based on the uplink demand information. The operation of the physical button can be long pressing the physical button for a preset time, clicking the physical button, or clicking the physical button for a preset number of times.

[0102] Step S202: The terminal device sends a request message to the virtualized BaaS platform, wherein the request message includes the user's on-chain demand information; the virtualized BaaS platform communicates and connects with multiple BaaS platforms of various types of alliance chains.

[0103] After the terminal device generates a request message according to the on-chain demand information input by the user, the terminal device sends a request message including the user's on-chain demand information to the virtualized BaaS platform. Optionally, the terminal device can send the request message to the virtualized BaaS platform through interfaces such as API and SDK. Among them, the request message contains the user's on-chain demand information.

[0104] The virtualized BaaS platform can be connected to the BaaS platforms corresponding to the various types of alliance chains through interfaces, that is, the virtualized BaaS platform can be connected to the multiple BaaS platforms through interfaces. Each type of alliance chain can include at least one blockchain.

[0105] Optionally, multiple types of alliance chains include but are not limited to at least two of the following alliance chains: Spark Chain, Unicom Chain, Changan Chain, and Super Chain. For example, Figure 1 Blockchain 106, blockchain 108, and blockchain 109 may be three different types of blockchains, namely, Spark Chain, Unicom Chain, Changan Chain, and Super Chain. Blockchain 107 may be the same type of blockchain as blockchain 106.

[0106] Step S203: The virtualized BaaS platform obtains the first blockchain that matches the on-chain demand information.

[0107] After the terminal device sends a request message including the on-chain requirement information to the virtualized BaaS platform, the virtualized BaaS platform receives the request message including the on-chain requirement information sent by the terminal device. The virtualized BaaS platform obtains the first blockchain matching the on-chain requirement information according to the request message including the on-chain requirement information.

[0108] In one implementation, the first blockchain is one of the multiple types of alliance chains corresponding to the multiple BaaS platforms mentioned above.

[0109] In another implementation, there is no blockchain matching the on-chain demand information in the multiple types of alliance chains corresponding to the above-mentioned multiple BaaS platforms. In this case, the first blockchain is a blockchain matching the on-chain demand information built according to the on-chain demand information.

[0110] Step S204: The virtualized BaaS platform sends a feedback message to the terminal device, where the feedback message includes the first identifier of the first blockchain.

[0111] After the virtualized BaaS platform obtains the first blockchain that matches the on-chain demand information, it can send a feedback message to the terminal device through the interface, and the feedback message includes the first identifier of the first blockchain.

[0112] Optionally, the first identifier is a unique ID of the first blockchain.

[0113] It should be noted that the embodiment of the present application does not specifically limit the first identifier, and it can be selected according to actual conditions.

[0114] Optionally, in step S202, the request message sent by the terminal device to the virtualized BaaS platform may also include indication information for indicating a second blockchain, wherein the second blockchain may be a blockchain specified by the user that the user wishes to use. Then, after the virtualized BaaS platform obtains the first blockchain that matches the on-chain demand information and before sending a feedback message to the terminal device, the virtualized BaaS platform determines whether the second blockchain is the same as the first blockchain based on the indication information.

[0115] When the second blockchain is the same as the first blockchain, accordingly, the feedback message also includes first reminder information, and the first reminder information is used to remind the user that the second blockchain is the same as the first blockchain.

[0116] Optionally, when the second blockchain is different from the first blockchain, the feedback message also includes second reminder information, and the second reminder information is used to suggest to the user to use the first blockchain for on-chain operation. Optionally, the second reminder information is also used to remind the user that the second blockchain is different from the first blockchain.

[0117] Among them, when the user specifies a blockchain, the request message also includes indication information for indicating the second blockchain. The virtualized BaaS platform determines whether the second blockchain indicated by the user is the same as the first blockchain obtained by the virtualized BaaS platform and matching the on-chain demand information according to the indication information contained in the request message. This embodiment allows the user to know whether the blockchain he wants to use is consistent with the first blockchain obtained by the virtualized BaaS platform and matching the on-chain demand information, while fully considering the user's needs and ensuring the accuracy of the blockchain selected by the user.

[0118] Step S205: the terminal device sends a chain request to the virtualized BaaS platform, where the chain request includes a first identifier and information to be chained.

[0119] When a user needs to store evidence on the blockchain, the user sends a request to the virtualized BaaS platform through a terminal device. The request includes a first identifier and information to be uploaded. Optionally, the information to be uploaded includes the uploaded data and a second identifier corresponding to the uploaded data.

[0120] For example, when video information needs to be stored on the chain, the data on the chain in the information to be stored on the chain may include video data, video shooting time, name of the device that shot the video, etc. When a contract needs to be stored on the chain, the data on the chain in the information to be stored on the chain may include the hash value of the contract.

[0121] Step S206: The virtualized BaaS platform sends a chain request to the first BaaS platform of the first blockchain, so that the information to be chained is written into the first blockchain.

[0122] The virtualized BaaS platform receives the on-chain request sent by the terminal device, and the virtualized BaaS platform determines the first blockchain that matches the on-chain demand information according to the first identifier in the on-chain request, and the virtualized BaaS platform stores the correspondence between the BaaS platform and the blockchain. The virtualized BaaS platform determines the BaaS platform corresponding to the first blockchain according to the correspondence, so that the virtualized BaaS platform determines the first BaaS platform of the first blockchain. The virtualized BaaS platform sends the on-chain request from the terminal device to the first BaaS platform of the first blockchain, so that the information to be on-chain is written into the first blockchain.

[0123] The data processing method based on blockchain provided in this embodiment is executed by the following steps: after the terminal device receives the on-chain demand information input by the user, it sends a request message including the on-chain demand information of the user to the virtualized BaaS platform. The virtualized BaaS platform obtains the first blockchain matching the on-chain demand information according to the request message, and the virtualized BaaS platform sends a feedback message including the first identifier of the first blockchain to the terminal device. The terminal device sends a request for on-chain including the first identifier and the information to be on-chain to the virtualized BaaS platform, and the virtualized BaaS platform sends a request for on-chain to the first BaaS platform of the first blockchain so that the information to be on-chain is written into the first blockchain. Compared with the prior art, in this embodiment, when the user has any on-chain demand, the terminal device can directly send a request message including the on-chain demand information to the virtualized BaaS platform through the terminal device, so that the virtualized BaaS platform can obtain the blockchain matching the on-chain demand information; the terminal device sends a request for on-chain including the identifier of the blockchain to the virtualized BaaS platform, so that the BaaS platform of the blockchain completes the on-chain operation. That is to say, no matter what type of alliance chain a user uses, it will be connected to the virtualized BaaS platform, and there is no need to change the BaaS platform. And because no matter what type of alliance chain a user uses, it will be connected to the virtualized BaaS platform, the same rules will be used when a user uses any type of alliance chain, making it simple and convenient for users to use the alliance chain and improving the user experience.

[0124] The following uses Figure 3 The illustrated embodiment provides a detailed description of an implementation method of step S203 in implementation one, "the virtualized BaaS platform obtains a first blockchain that matches the on-chain demand information."

[0125] Figure 3 A flowchart of the second embodiment of the data processing method based on blockchain provided by this application;

[0126] Step S301: The virtualized BaaS platform obtains the on-chain demand information in the request message.

[0127] After receiving the request message, the virtualized BaaS platform obtains the chain demand information in the request message.

[0128] Step S302: The virtualized BaaS platform obtains the first blockchain that matches the on-chain demand information through a matching model based on the on-chain demand information.

[0129] When the first blockchain is one of the multiple types of alliance chains corresponding to the above-mentioned multiple BaaS platforms, the virtualized BaaS platform obtains the first blockchain that matches the on-chain demand information from multiple blockchains in the multiple types of alliance chains corresponding to the multiple BaaS platforms through a matching model based on the on-chain demand information.

[0130] When the first blockchain is a blockchain built according to the on-chain demand information and matching the on-chain demand information, the virtualized BaaS platform obtains the first blockchain matching the on-chain demand information through a matching model according to the on-chain demand information, including:

[0131] The virtualized BaaS platform determines that there is no blockchain matching the on-chain demand information among various types of alliance chains based on the on-chain demand information and matching model;

[0132] The virtualized BaaS platform builds the first blockchain that matches the on-chain demand information based on the on-chain demand information;

[0133] The virtualized BaaS platform establishes a communication connection between the virtualized BaaS platform and the first BaaS platform, and the first BaaS platform is the BaaS platform of the first blockchain.

[0134] If the first BaaS platform that establishes a communication connection with the virtualized BaaS platform does not have a first BaaS platform that is in communication connection with the first blockchain, the method further includes:

[0135] The virtualized BaaS platform builds the first BaaS platform that is connected to the first blockchain for communication.

[0136] Specifically, in one implementation, after the virtualized BaaS platform in this embodiment obtains the on-chain demand information, it converts the on-chain demand information into a multi-dimensional vector, which is the input vector of the matching model; the multi-dimensional vector is input into the matching model, and the first blockchain is determined according to the output of the matching model.

[0137] Optionally, the virtualized BaaS platform uses the TextRank algorithm to convert the on-chain demand information into a multi-dimensional vector, which may include:

[0138] a1. The virtualized BaaS platform performs word segmentation and word tagging on each item of information included in the on-chain demand information, removes useless words and retains key words, and extracts a keyword set of the on-chain demand information; wherein each type of parameter information selected by the user based on the terminal device corresponds to an item of information in the on-chain demand information.

[0139] For example, the number of block transactions and the required capacity of the block can be a type of parameter information, and the number of consensus nodes and consensus strategy of the blockchain can be a type of parameter information.

[0140] a2. The virtualized BaaS platform converts the keyword set into a matrix based on the keywords corresponding to each piece of information to obtain a keyword matrix.

[0141] Optionally, each column of the keyword matrix corresponds to a keyword of an item of information.

[0142] a3. Construct a multi-dimensional vector based on the keyword matrix.

[0143] Each dimensional vector of the multidimensional vector is a vector corresponding to an item of information in the uplink demand information.

[0144] Optionally, the matching model can be a pre-trained neural network model, such as a back propagation neural network model, a deep neural network model, or a bidirectional neural network model. At this time, the multidimensional vector is input into the matching model, and a specific implementation of determining the first blockchain according to the output of the matching model can be as follows:

[0145] Feeding multidimensional vectors into a neural network model Among them, the activation function w i is the weight value, θ is the threshold, x i Represents the input value, and y is the output result. The virtualized BaaS platform stores the matching relationship between y and the blockchain. The matching blockchain can be determined based on the output result y, or it can be determined that no blockchain is matched based on the output result y.

[0146] A training method for the matching model is described below.

[0147] In one implementation, obtaining a matching model includes:

[0148] b1. Obtain multiple training samples, each of which includes chain-up requirement information and labels.

[0149] The on-chain requirement information included in each training sample is different. The on-chain requirement information included in each training sample can be obtained by the user based on the parameter information set. The label of the training sample is used to indicate the blockchain that matches the on-chain requirement information included in the training sample. Optionally, the label can be a vector.

[0150] b2. Determine the initialization neural network model, and perform training based on the initialization neural network model and multiple training samples to obtain a matching model.

[0151] For each training sample, the above-mentioned method of obtaining a multidimensional vector according to a request message is used to obtain the multidimensional vector corresponding to the training sample, and the multidimensional vector is input into the matching model of the currently obtained intermediate state to obtain an actual output. According to the actual output, the label (that is, the expected output) and the loss function, the error between the expected output and the actual output is calculated. If the error is large, the gradient descent method is used to adjust the matching model of the currently obtained intermediate state to obtain a new matching model of the intermediate state until the error is lower than the preset threshold, and finally the matching model is obtained. Among them, the preset threshold is set by the user. The embodiment of the present application does not specifically limit the preset threshold, and it can be limited according to the actual situation.

[0152] Optional, matches the number of neurons in the model's hidden layer c is the number of neurons in the input layer, d is the number of neurons in the output layer, and a is a constant between [1,10].

[0153] The blockchain-based data processing method provided in this embodiment is a virtualized BaaS platform that determines the first blockchain based on the on-chain demand information and the matching model in the request message, and the efficiency and accuracy of determining the first blockchain are both high.

[0154] The following uses Figure 4 The illustrated embodiment provides a detailed description of another implementation method of step S203 in implementation one, "the virtualized BaaS platform obtains a first blockchain that matches the on-chain demand information."

[0156] Step S401: The virtualized BaaS platform obtains the on-chain demand information in the request message.

[0157] After receiving the request message, the virtualized BaaS platform obtains the chain demand information in the request message.

[0158] Step S402: The virtualized BaaS platform obtains a first blockchain that matches the on-chain demand information based on the on-chain demand information and the corresponding relationship; the corresponding relationship includes multiple preset on-chain demand information and the blockchain corresponding to each preset on-chain demand information.

[0159] When the first blockchain is one of the multiple types of alliance chains corresponding to the above-mentioned multiple BaaS platforms, the virtualized BaaS platform obtains the first blockchain corresponding to the on-chain demand information according to the on-chain demand information and the corresponding relationship, including: the virtualized BaaS platform obtains the target blockchain corresponding to the on-chain demand information indicated in the corresponding relationship, determines that the target blockchain is one of the multiple types of alliance chains corresponding to the above-mentioned multiple BaaS platforms, and uses the target blockchain as the first blockchain.

[0160] When the first blockchain is a blockchain matching the on-chain demand information and built according to the on-chain demand information, the virtualized BaaS platform obtains the first blockchain matching the on-chain demand information according to the on-chain demand information and the corresponding relationship, including:

[0161] The virtualized BaaS platform determines that there is no blockchain matching the on-chain demand information among the various types of alliance chains based on the on-chain demand information and the corresponding relationship;

[0162] The virtualized BaaS platform builds the first blockchain that matches the on-chain demand information based on the on-chain demand information;

[0163] The virtualized BaaS platform establishes a communication connection between the virtualized BaaS platform and the first BaaS platform, and the first BaaS platform is the BaaS platform of the first blockchain.

[0164] The blockchain-based data processing method provided in this embodiment is a virtualized BaaS platform that obtains the first blockchain corresponding to the preset chain demand information according to the corresponding relationship between the chain demand information and the blockchain, thereby further improving the accuracy of determining the first blockchain.

Figure 5 After step S206 "the virtualized BaaS platform sends a chain request to the first BaaS platform of the first blockchain, so that the first BaaS platform performs a chain operation to write the information to be chained into the first blockchain", the blockchain-based data processing method further includes the following steps:

[0166] Step S501: The terminal device receives query information input by the user.

[0167] When a user needs to query the on-chain data of the on-chain operation, the user enters query information on the terminal device. The query information may include a first identifier of the first blockchain and a second identifier corresponding to the on-chain data.

[0168] Step S502: The terminal device sends a query request to the virtualized BaaS platform.

[0169] In the above steps, when the user needs to query the on-chain data of the on-chain operation, the user enters the query information on the terminal device, and the terminal device generates a query request according to the query information entered by the user. The query request includes the above query information, and the query request is used to request to query the on-chain data of the on-chain operation. The terminal device sends the generated query request to the virtualized BaaS platform.

[0170] Step S503: The virtualized BaaS platform determines the first BaaS platform of the first blockchain according to the query request.

[0171] After the virtualized BaaS platform receives the query request, the virtualized BaaS platform determines the first blockchain according to the first identifier of the first blockchain in the query request, and determines the first BaaS platform according to the corresponding relationship between the BaaS platform and the blockchain.

[0172] Step 504: The virtualized BaaS platform sends a query request to the first BaaS platform of the first blockchain.

[0173] After the virtualized BaaS platform determines the first BaaS platform of the first blockchain, the virtualized BaaS platform sends a query request to the first BaaS platform of the first blockchain.

[0174] Step S505: The first BaaS platform obtains the queried on-chain data according to the query request.

[0175] The first BaaS platform receives the query request to obtain the on-chain data corresponding to the second identifier stored on the first blockchain.

[0176] Step S506: The first BaaS platform sends the queried on-chain data to the virtualized BaaS platform.

[0177] After the first BaaS platform obtains the queried on-chain data according to the query request, it sends the queried on-chain data to the virtualized BaaS platform.

[0178] Step S507: The virtualized BaaS platform sends the queried on-chain data to the terminal device.

[0179] In the above steps, after the first BaaS platform sends the on-chain data of the on-chain operation to the virtualized BaaS platform, the virtualized BaaS platform receives it and then sends it to the terminal device through the interface, and the user can view the on-chain data on the terminal device.
