[0026] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0027] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0028] First, let’s explain the terms involved in this application:

[0029] Blockchain refers to a decentralized, distributed database or public ledger technology that records and verifies data through a consensus mechanism among network nodes. Each block contains all information exchanged within the system over a specific period of time, and is linked in chronological order to form a chain.

[0030] With the rapid development of technologies like the Internet of Things and blockchain in supply chain finance, biological asset regulation, as a key component of supply chain finance, has also seen significant progress. There is an urgent need to break away from traditional farming models and introduce standardized, information-based, end-to-end production models based on technologies like the Internet of Things and blockchain. This will create a modern, efficient, safe, high-quality, and ecologically sustainable production method, helping to upgrade traditional agriculture. At the same time, as the scope of live livestock and poultry mortgage financing continues to expand, the demand for collecting and monitoring biological data on livestock and poultry, as well as the behavioral data of relevant parties, is also increasing. Given the risks associated with long livestock and poultry farming cycles, weak risk tolerance, and rapidly changing markets, banks, insurance companies, and other relevant parties need to develop a credible and operational regulatory approach to verify risks.

[0031] The asset supervision method based on smart contracts provided in the embodiment of the present application can build a set of quantifiable, verifiable and automatically executed smart contract triggering mechanisms based on the biological signs data of the biological assets of the farmers (such as body temperature, activity level, eating frequency, disease occurrence, etc.) and the service information between them and the service providers (such as compensation records, response time, service quality, etc.). By collecting these key data in real time and storing them on the chain, it is possible to dynamically evaluate the farmers' hygiene level, performance ability and risk status on the basis of ensuring the authenticity, non-tamperability and traceability of the data, and set the triggering conditions of the smart contract accordingly. Based on this, the contract mechanism based on data solves the problems of relying on manual judgment, information lag and vague standards in traditional breeding supervision.

[0032] Furthermore, by codifying rules through smart contracts, the rights and obligations between farmers and service providers are automatically enforced when specific conditions are met, reducing disputes and breaches of contract. Combined with the distributed nature of blockchain, the actions of all participants are transparently recorded. This, coupled with a dynamic reputation model, further incentivizes all parties to operate in a standardized manner and actively fulfill their obligations, thereby achieving comprehensive regulatory oversight.

[0033] Figure 1 The scenario diagram of the asset supervision method based on smart contracts provided for this application is as follows: Figure 1 As shown, the specific application scenarios of this application include: biological assets equipped with chips, NB-IoT wireless communication modules, 5G smart gateways, patrol robots, network servers and application servers, Internet of Things platforms, and blockchains.

[0034] Among them, biological assets equipped with chips can refer to each biological asset wearing a device with a built-in chip, which can monitor and record biological vital signs data in real time, such as body temperature and activity level.

[0035] The NB-IoT wireless communication module can be used to transmit data collected by the chip to the 5G smart gateway. NB-IoT is a low-power wide-area network technology suitable for long-distance, low-bandwidth data transmission.

[0036] The 5G smart gateway can receive data from the NB-IoT module and transmit the data to the cloud server through the 5G network.

[0037] The patrol robot can automatically patrol the farm, detect environmental parameters (such as temperature and humidity), monitor animal behavior, and send data to the 5G smart gateway via the wireless network.

[0038] The network server and application server are responsible for receiving data from the 5G smart gateway and performing preliminary processing. The application server further analyzes and processes the data to generate various reports and warning information.

[0039] The IoT platform can be a comprehensive management platform that stores and manages all collected data and provides functions such as data analysis and visualization.

[0040] Blockchain is used to ensure data security and immutability. All processed data will eventually be uploaded to the blockchain to ensure data authenticity and transparency.

[0041] Chips attached to biological assets collect real-time biometric data and transmit it to a 5G smart gateway via an NB-IoT wireless communication module. Patrol robots also collect environmental and behavioral data and transmit it to the 5G smart gateway via the wireless network. The 5G smart gateway receives the data and transmits it to a network server via the 5G network. The network server performs preliminary processing on the data and then passes it to an application server for in-depth analysis and processing. Based on pre-set rules and algorithms, the application server generates various reports and warnings. The processed data is then uploaded to the IoT platform for storage and management. Finally, all critical data is uploaded to the blockchain to ensure data security and immutability.

[0042] As a result, farms can achieve real-time monitoring and management of biological assets, improve breeding efficiency and safety, reduce human intervention and errors, and improve overall management level. Service providers can obtain real-time vital data and service performance information of farmers' biological assets, accurately grasp service needs and risk conditions, and thus improve response speed and service quality.

[0043] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0044] Figure 2 The flowchart of the asset supervision method based on smart contracts provided for this application is as follows: Figure 2 As shown, the method includes:

[0045] S201. After the farmer and the service provider sign a smart contract in the blockchain, the biological sign data of the farmer's biological assets and the service information between the farmer and the service provider are obtained. The service provider includes at least one of a bank, an insurance company, and a vaccine and pharmaceutical company.

[0046] Among them, breeders can refer to individuals or organizations engaged in large-scale and professional breeding of biological assets such as livestock and poultry, which can include individual farmers, family farms, agricultural cooperatives and breeding enterprises.

[0047] Service providers can refer to companies or organizations that provide a variety of professional services and support to farmers, covering multiple aspects of farming production and management operations. These services include, but are not limited to, feed supply, veterinary services, disease prevention and control, installation and maintenance of environmental monitoring equipment, farming technology consulting, financial support (such as loans and insurance services), market information, and sales channels.

[0048] Smart contracts can be defined as automated protocols running on blockchain technology that automatically execute, control, or document events and actions based on pre-defined conditions and rules. Smart contracts can exist in the form of code and be embedded directly into the blockchain, ensuring a high degree of transparency, immutability, and decentralization in their execution. Smart contracts enable trusted transactions and agreements between two or more parties without an intermediary. Once predetermined conditions are met (such as the delivery of goods, the arrival of funds, or the arrival of a specific time point), the contract automatically executes its terms, such as disbursement, release of funds, or updating of records.

[0049] In an embodiment of the present application, the smart contract can be determined based on the service providers involved in the supervision of biological assets. For example, when the service providers include banks, insurance companies and vaccine and pharmaceutical companies, the smart contract can include a four-party smart contract signed by the farmer, the bank, the insurance company and the vaccine and pharmaceutical company for the farmer's biological assets within period T, a first smart contract signed by the farmer and the bank, a second smart contract signed by the farmer and the insurance company, and a fourth smart contract signed by the farmer and the vaccine and pharmaceutical company.

[0050] Among them, the four-party smart contract is used to stipulate the rights and obligations of farmers, banks, insurance companies and vaccine and pharmaceutical companies within period T. The four parties confirm the details of the four-party smart contract and use their respective private keys on the blockchain to sign the four-party smart contract to ensure the validity of the contract.

[0051] The first smart contract stipulates that if a farmer applies for a loan and meets the contractual conditions, the bank will disburse the loan, using the biological assets as collateral. The first smart contract also stipulates the repayment method, time, and amount. Both parties can confirm the details of the first smart contract and sign it using their respective private keys on the blockchain to ensure its validity.

[0052] The second smart contract is used to stipulate that after the farmer applies for compensation and meets the contract conditions, the insurance company will pay the farmer the claim, and at the same time stipulate the claim mode, time and amount; both parties confirm the details of the second smart contract and use their respective private keys on the blockchain to sign the second smart contract to ensure the validity of the contract.

[0053] The third smart contract is used to stipulate that after the vaccine and pharmaceutical company provides vaccines and drugs to farmers, the fees will be charged according to the established model and time after the contract conditions are met. Both parties confirm the details of the third smart contract and use their respective private keys on the blockchain to sign the third smart contract to ensure the validity of the contract.

[0054] The biological assets of farmers can refer to living animals with economic value raised or cultivated by farmers, such as cattle, sheep, pigs, chickens, ducks and other livestock and poultry, which are core resources in agricultural production.

[0055] Biosignal data for biological assets refers to a range of health and growth indicators collected from live animals via various sensors and monitoring devices. These data are crucial for assessing the condition of biological assets. This data includes, but is not limited to, weight, temperature, heart rate, respiratory rate, activity level, feed consumption, and disease symptoms. By monitoring and analyzing this real-time biosignal data, farmers and service providers can promptly assess the health and growth progress of their animals, predict potential risks, and implement necessary interventions to ensure animal welfare and production efficiency.

[0056] In some embodiments, biological asset biometric data can be collected in real time using IoT devices. For example, in smart farming scenarios, farmers can attach smart ear tags or implantable sensors to livestock (such as cattle and pigs). These devices can continuously monitor key physiological indicators such as body temperature, heart rate, activity level, and feeding frequency, and upload the data to a cloud platform via wireless networks (such as NB-IoT, LoRa, and 5G).

[0057] Service information between farmers and service providers refers to all interaction records and business data generated between farmers and various professional service providers (such as feed suppliers, veterinary institutions, insurance companies, financial institutions, technical service providers, etc.) during the breeding and production process. This information includes, but is not limited to, service content, service time, service results, payment status, performance status, and implementation of contract terms, reflecting the collaborative process between the two parties in areas such as breeding management, disease prevention and control, financial support, and equipment maintenance.

[0058] S202. Determine the contract triggering conditions between the farmer and the service provider in the smart contract based on the biological sign data of the farmer's biological assets and the service information between the farmer and the service provider.

[0059] The contract trigger condition can refer to a set of executable rules or event thresholds pre-set in the smart contract to determine whether the conditions for automatic contract execution are met. In the embodiment of the present application, the condition can be dynamically set and verified based on the biological sign data of the farmer's biological assets (such as weight growth, health status, survival rate, etc.) and the service information between the farmer and the service provider (such as feed supply records, vaccination status, insurance claim terms, loan repayment nodes, etc.).

[0060] In this embodiment of the present application, when the service provider is a bank, the contract triggering conditions between the farmer and the service provider in the smart contract are determined based on the biological sign data of the farmer's biological assets and the service information between the farmer and the service provider, including:

[0061] Determine the comprehensive breeding level factor of the farmer based on the biological sign data of the farmer's biological assets;

[0062] Determine the comprehensive repayment ability factor of the farmer based on the service information between the farmer and the service provider;

[0063] Based on the comprehensive breeding level factor and the comprehensive repayment ability factor, the contract triggering conditions between the breeder and the service provider in the smart contract are determined.

[0064] The comprehensive breeding level factor refers to a comprehensive coefficient reflecting a farmer's overall breeding efficiency and management level, derived from a series of quantitative indicators, based on the biological data of the farmer's biological assets. This factor incorporates data analysis results from multiple dimensions, including but not limited to key vital signs such as animal growth rate (e.g., daily weight gain), health status (e.g., disease incidence and survival rate), reproductive performance (e.g., litter size), and feed conversion rate. Through continuous monitoring and scientific analysis of this data, we can gain a comprehensive understanding of a farmer's breeding performance at different stages and their ability to cope with risks.

[0065] The comprehensive repayment capacity factor is a comprehensive indicator of a farmer's ability to repay debts, based on information collected between the farmer and its service providers. This factor can be determined by analyzing the farmer's financial health, credit history, historical transaction data, and partnerships with various service providers (such as feed suppliers, financial institutions, and insurance companies).

[0066] When the service provider is a bank, the contract triggering conditions between the farmer and the bank are met:

[0133] S203. When the contract triggering conditions meet the preset triggering conditions, notify the service provider to execute the agreement in the smart contract.

[0134] Among them, the preset trigger conditions can refer to a set of rules or threshold conditions pre-set by farmers and service providers (such as insurance companies, financial institutions, farming service companies, etc.) at the beginning of the deployment or signing of the smart contract, which are used to determine whether a certain operation in the contract should be triggered (such as compensation, early warning, loan issuance, service startup, etc.).

[0135] An agreement can refer to the specific execution content or obligation terms agreed upon by both parties in a smart contract. Once the trigger conditions are met, the corresponding actions will be executed according to the agreement.

[0136] In an embodiment of the present application, when the farmer's data is spread to the blockchain through the P2P network, it serves as the basis for the biological asset-related parties to trigger the smart contract terms and establish the content of the next smart contract. The smart contracts involving biological asset-related parties in the blockchain will regularly check the status of the automaton, traverse the state machine, transactions and trigger conditions contained in each contract one by one; push transactions that meet the conditions to the queue to be verified and wait for consensus; transactions that do not meet the trigger conditions will continue to exist in the blockchain. When the transaction enters the latest round of verification, it will be spread to each biological asset-related party node for verification and consensus, after which the transaction will be successfully executed and the user will be notified. After the transaction is successfully executed, the state machine of the smart contract will determine the status of the contract to which it belongs. When all the transactions included in the contract are executed sequentially, the state machine will mark the status of the contract as completed and remove the contract from the latest block; otherwise, it will be marked as in progress and continue to be saved in the latest block waiting for the next round of processing until it is completed. The entire transaction and status processing is automatically completed by the smart contract system built into the bottom layer of the blockchain.
