[0001] This invention relates to the field of blockchain access control technology, and in particular to a data processing method and apparatus based on blockchain. Background Technology

[0002] An e-commerce platform is essentially a platform that provides online transaction negotiation for businesses or individuals. Current internet e-commerce platforms are centralized, with a single company providing centralized servers to handle operations such as product listing, reviews, and order placement. However, because these operations are performed by a single company's centralized servers, centralized e-commerce platforms struggle to conduct compliance checks on product data, leading to compliance issues. Furthermore, this centralized system also means that some private data, such as transaction data, payment data, and browsing habits, is controlled by that single company, raising trust concerns.

[0006] If it is a risk request, a detection request is sent to the first blockchain network so that the first blockchain network can perform risk detection on the first commodity data, and the detection result of the risk detection is stored in the first blockchain network;

[0007] If the detection result is passed, a first business request is sent to the second blockchain network so that the second blockchain network can perform a first processing on the first commodity data, and the processing result of the first processing is stored in the second blockchain network.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention. Furthermore, the acquisition, storage, use, and processing of data in the technical solutions of this application all comply with the relevant provisions of national laws and regulations.

[0027] With the development of the information age, more and more digital content is being published online by creators, sharing knowledge creation through free or paid means. Digital content, such as images, articles, audio, and video, is easily copied, making it difficult to effectively protect creators' copyrights and leading to problems like information misuse. Traditional centralized e-commerce platforms struggle to conduct compliant inspections of product data, making them prone to product piracy and infringement, and difficult to trace. Furthermore, traditional centralized e-commerce platforms are often provided by a single company. Some private data, such as transaction data, payment data, and browsing habits, are also held by this single company, raising trust issues. Additionally, traditional centralized e-commerce platforms often record user habits and browsing history for recommendation purposes. While these functions meet users' personalized needs, they also pose a risk of personal information leakage.

[0028] Proposed by Ethereum co-founder Gavin Wood in 2014, Web 3.0 represents the next generation of decentralized internet and imbues it with individual value. Web 3.0 focuses on the "who creates, who owns" relationship value formed through decentralized technologies such as blockchain. Based on blockchain, Web 3.0 inherently possesses decentralized characteristics. Simultaneously, users have complete control over the data value they create. Every action and every trace people leave on the internet is recorded, quantified, and added to the data value chain.

[0029] This specification describes an embodiment of a decentralized e-commerce platform implemented using blockchain technology based on Web3.0 technology. This aims to address compliance and trust issues faced by traditional centralized e-commerce platforms.

[0030] A blockchain is a distributed ledger that organizes multiple data blocks in a chain-like structure according to chronological order, and uses cryptographic algorithms to ensure security, traceability, and immutability. Blockchains can include public blockchains, consortium blockchains (also known as federated blockchains), private blockchains, etc. The distributed ledger is jointly maintained by multiple node devices in the blockchain network. The blockchain network is formed by multiple node devices through a consensus mechanism. The blockchain network can include, for example, a peer-to-peer network (P2P network). The consensus mechanism can be based on algorithms such as Proof of Work (POW), Proof of Stake (POS), Delegated Proof of Stake (DPoS), or Practical Byzantine Fault Tolerance (PBFT). By deploying smart contracts in the blockchain, the blockchain can have smart contract functionality. A smart contract is a computer program that can run on the node devices of the blockchain network. Deployment of smart contracts can be achieved through transactions. For example, business personnel can use high-level computer languages ​​to write smart contracts. By compiling the written smart contracts, bytecode can be obtained. Blockchain node devices can construct transactions for deploying smart contracts based on the bytecode. By submitting these transactions to the blockchain network, smart contracts can be deployed on the blockchain.

[0031] Please see Figure 1 and Figure 2 This specification provides an example of a blockchain-based data processing system.

[0032] The data processing system may include multiple components such as terminal devices, platform devices, a first blockchain network, and a second blockchain network. The terminal devices may be user-facing devices, and users may include merchants and consumers. These terminal devices include, but are not limited to, smartphones, tablets, and personal computers. The platform device can be understood as a product shelf, serving as a platform for transactions between users based on this product shelf. The platform device may include servers, etc. The platform device may be established by a platform provider, which may include enterprises or individuals providing online transaction negotiation services. The first blockchain network can be used for risk detection, such as compliance checks. The first blockchain network can store the detection results of risk checks. The first blockchain network may include multiple first node devices. The first node devices may be established by regulatory agencies. The second blockchain network can be used for business processing, such as product listing, product reviews, product queries, product ordering, and product payment. The second blockchain network can store the processing results of business processing. The second blockchain network may include multiple second node devices. The second node devices may be established by users. This two-layer blockchain network architecture enables a controllable, reliable, decentralized, and distributed e-commerce system. Furthermore, regulatory agencies can establish blockchain networks, and users can also establish their own. Through platform devices, blockchain networks established by regulatory agencies can be connected to user-established blockchain networks, eliminating the need for both agencies and users to jointly establish new networks, thus saving costs.

[0033] A terminal device can send a product processing request to a platform device, the product processing request including first product data. The platform device can receive the product processing request; it can determine whether the product processing request is a risk request; if it is a risk request, it can send a detection request to a first blockchain network. The first blockchain network can perform risk detection on the first product data. If the detection result is successful, the platform device can send a first business request to a second blockchain network, the first business request including the first product data. The second blockchain network can perform first processing on the first product data. The platform device can obtain the processing result of the first processing; it can send first information to the terminal device. The first information indicates successful processing. If the detection result is unsuccessful, the platform device can send second information to the terminal device. The second information indicates processing failure. If it is not a risk request, the platform device can send a second business request to the second blockchain network, the second business request including the first product data. The second blockchain network can perform second processing on the first product data. The platform device can obtain the processing result of the second processing; it can send third information to the terminal device. The third information can include the processing result of the second processing.

[0034] Please see Figure 3 and Figure 4 This specification provides a blockchain-based data processing method. The data processing method uses a platform device as the executing entity and may specifically include the following steps.

[0035] Step S11: Receive a product processing request, the product processing request including first product data.

[0036] In some embodiments, the terminal device may send a product processing request to the platform device. The product processing request may include first product data. The first product data may include image data, text data, etc. The first product data may include data on products to be listed, product review data, product order data, and query conditions for querying products, etc. In practical applications, the terminal device may provide an interactive interface; it may obtain the first product data based on the interactive interface; and after detecting a sending instruction, it may send a product processing request to the platform device. The product may include physical goods. Physical goods may include electronic products, clothing, etc. Of course, the product may also include virtual goods. Virtual goods may include coupons, points, red envelopes, etc.

[0037] Step S12: Determine whether the product processing request is a risky request.

[0038] In some embodiments, whether the product processing request is a risky request in practical applications may include the following situations: Situation 1. Whether the first product data itself is risky data. For example, the first product data may be abnormal product data. The abnormal product data may include product data with risks such as illegal information trading and dissemination, pornography, or terrorism. Such abnormal product data is detrimental to the healthy and orderly development of the Internet. Situation 2. Whether the first product data was generated under abnormal circumstances. For example, the first product data may include product order data. The order data may be generated under a fraudulent order scenario, or it may be generated under a stolen account scenario. First product data generated under abnormal circumstances will interfere with the normal operation of the e-commerce platform.

[0039] In some embodiments, the type of a product processing request can be identified; based on the type, it can be determined whether the product processing request is a risk request. Specifically, the product processing request may include the values ​​of one or more fields. For example, the fields may include a first field, a second field, etc. The first field is used to indicate the type of the product processing request, and the second field is used to indicate the data carried by the product processing request. Thus, the product processing request can be parsed to obtain the field values; based on the field values, the type of the product processing request can be identified. A type set can be pre-defined. The type set may include one or more request types involving risk. The type of the product processing request can be matched against the type set. If a match is successful, the product processing request can be determined to be a risk request. If a match fails, the product processing request can be determined to be a non-risk request.

[0040] Step S13: Send a detection request to the first blockchain network to perform risk detection on the first commodity data.

[0041] In some embodiments, if a product processing request is a risky request, a detection request can be sent to a first blockchain network to enable the first blockchain network to perform risk detection on the first product data. The detection result can be stored on the first blockchain network. The detection result can include pass or fail, etc. In this way, on the one hand, compliance issues can be avoided by performing risk detection on the first product data. On the other hand, performing risk detection on the first product data when a product processing request is determined to be a risky request avoids performing risk detection on all product processing requests, reducing the number of risk detections, saving time, and improving request processing efficiency.

[0042] In some embodiments, smart contracts may be deployed in the first blockchain network. The platform device may send a detection request to a first node device in the first blockchain network. The detection request may include first product data. Specifically, the platform device may send the detection request to any one of the first node devices. The first node device may receive the detection request; may construct a detection transaction based on the first product data; and may invoke the smart contract deployed in the first blockchain network based on the detection transaction to perform risk detection on the first product data and obtain the detection result of the first product data. The detection result of the first product data may be written into the blockchain of the first blockchain network.

[0043] It's worth noting that in the field of blockchain technology, transactions can be categorized into narrow and broad types. Narrowly defined transactions include those that facilitate value transfer, such as money transfers. Broadly defined transactions can include services that fulfill user intentions, such as renting a property, storing evidence, vehicle dispatching, and insurance claims.

[0044] Step S14: If the detection result is passed, send the first business request to the second blockchain network to perform the first processing on the first commodity data.

[0045] In some embodiments, the first blockchain network can send the detection results of the first commodity data to the platform device. In practical applications, the first node device can send the detection results of the first commodity data to the platform device. The platform device can receive the detection results of the first commodity data. Specifically, the first node device can proactively send the detection results of the first commodity data to the platform device. Alternatively, the platform device can also send a detection result query request to the first node device. The first node device can receive the detection result query request; can query the detection results of the first commodity data from the blockchain; and can send the detection results of the first commodity data to the platform device.

[0046] In some embodiments, if the detection result of the first commodity data is passed, the platform device can send a first service request to the second blockchain network to enable the second blockchain network to perform a first processing on the first commodity data. The processing result of the first processing can be stored in the second blockchain network. In practical applications, the platform device can send the first service request to a second node device in the second blockchain network. The first service request may include the first commodity data. The platform device can send the first service request to any second node device. The second node device can receive the first service request; can construct a first processing transaction based on the first commodity data; and can execute the first processing transaction to perform a first processing on the first commodity data to obtain a processing result. The second node device can directly execute the first processing transaction. Alternatively, a smart contract can be deployed in the second blockchain network. The second node device can call the smart contract deployed in the second blockchain network to perform a first processing on the first commodity data.

[0047] Step S15: Feedback the first information, which indicates that the processing was successful.

[0048] In some embodiments, the second blockchain network can send the processing result of the first processing to the platform device. In practical applications, the second node device can send the processing result of the first processing to the platform device. The platform device can receive the processing result of the first processing. Specifically, the second node device can proactively send the processing result of the first processing to the platform device. Alternatively, the platform device can also send a processing result query request to the second node device. The second node device can receive the processing result query request; can query the processing result of the first processing from the blockchain; and can send the processing result of the first processing to the platform device.

[0049] After obtaining the processing result of the first process, the platform device can send first information to the terminal device. The first information indicates successful processing. The terminal device can receive and display the first information. Furthermore, the first information may also include the processing result of the first process.

[0050] In some embodiments, if the detection result is a failure, the platform device may send a second message to the terminal device. The second message indicates that the processing has failed. The terminal device may receive and display the second message.

[0051] In some embodiments, if it is not a risk request, the platform device can directly send a second business request to the second blockchain network to enable the second blockchain network to perform a second processing on the first commodity data. In practical applications, the platform device can send a second business request to a second node device in the second blockchain network. The second business request may include the first commodity data. Specifically, the platform device can send the second business request to any second node device. The second node device can receive the second business request; construct a second processing transaction based on the first commodity data; and execute the second processing transaction to perform a second processing on the first commodity data to obtain the processing result of the second processing. The second node device can directly execute the second processing transaction. Alternatively, a smart contract can be deployed in the second blockchain network. The second node device can call the smart contract deployed in the second blockchain network to perform a second processing on the first commodity data. The second blockchain network can send the processing result of the second processing to the platform device. In practical applications, the second node device can send the processing result of the second processing to the platform device. The platform device can receive the processing result of the second processing; and can provide feedback third information to the terminal device. The third information may include the processing result of the second processing. The terminal device can receive and display the third information.

The compliance detection smart contract is used to perform compliance detection on the first product data, such as detecting whether the first product data is abnormal product data. Specific detection rules are pre-written into the compliance detection smart contract by business personnel. For example, the first product may include text data. The compliance detection smart contract can detect whether the text data contains preset abnormal keywords. As another example, the first product data may include image data.

The compliance detection smart contract is used to perform compliance detection on the first product data, such as detecting whether the first product data is abnormal product data. Specific detection rules are pre-written into the compliance detection smart contract by business personnel. For example, the first product may include text data. The compliance detection smart contract can detect whether the text data contains preset abnormal keywords. As another example, the first product data may include image data.
