[0059] The storage module 103 is used to store data related to the completion of the target food product through the blockchain service network.

[0060] According to this embodiment, a blockchain-based full-process traceability system for a food supply chain is provided, comprising: an information collection module, an association module, and a storage module; wherein the information collection module is used to collect step information corresponding to each step included in the circulation process of the target food commodity; the association module is used to associate the target food commodity with the step information of each step in the circulation process of the target food commodity; the storage module is used to store the step information associated with the target food commodity through a blockchain service network. The present embodiment provides a food supply chain traceability system based on blockchain. The food supply chain traceability system based on blockchain collects step information of each step in the circulation process of the target food commodity, accurately determines the time and actual execution status of each step, and then associates the step information through the commodity feature identifier of the target food commodity to ensure that all relevant information for the same target food commodity is associated with the commodity feature identifier, so that when subsequent information is stored, it can all be stored in the transaction chain corresponding to the food commodity for storage, which is convenient for subsequent query; through the commodity feature identifier, the step information of the relevant commodities is uniformly stored, and the authenticity of the stored information is guaranteed by blockchain technology, and the authenticity of the transaction time is guaranteed based on its timestamp technology.

[0061] Figure 2 A flowchart of a blockchain-based information storage method for target food commodities according to one embodiment of the present invention is shown;

[0062] The method comprises the following steps:

[0063] Step S201: Obtain the commodity feature identifier of the target food commodity.

[0064] Step S202: Based on the commodity feature identifier of the target food commodity, determine whether a transaction chain corresponding to the commodity feature identifier already exists in the blockchain service network.

[0065] Specifically, if yes, execute step S203; if no, execute step S204.

[0066] In step S203, the step information of the current step associated with the target food commodity is added to the transaction chain corresponding to the commodity feature identifier to complete the information storage.

[0067] Step S204: Create a corresponding transaction chain based on the commodity feature identifier of the target food commodity, and add the step information of the current step to the transaction chain corresponding to the commodity feature identifier to complete information storage.

[0068] According to the above method, after obtaining the relevant step information, based on the product feature identifier, it is judged whether the relevant transaction chain already exists in the blockchain service network to determine whether a new transaction chain needs to be established, and then the information is stored. The authenticity of the stored information is guaranteed by blockchain technology, and the transaction time is determined using the corresponding timestamp. All the step information corresponding to the food product is accurately unified under the same product feature identifier, and the integration of the step information of the same food product is completed in chronological order, which is convenient for subsequent inquiries.

[0069] Figure 3 FIG1 shows a structural block diagram of a food supply chain traceability system based on blockchain according to another embodiment of the present invention. Figure 3 As shown, the system includes: an information collection module 301, an association module 302, a storage module 303 and a query module 304; wherein,

[0070] The functions that can be implemented by the association module 302 and the storage module 303 are the same as those described above and will not be described in detail here.

[0071] Specifically, the information collection module 301 is further configured to:

[0072] The participants in the procurement process include at least: suppliers and purchasers;

[0073] The step information corresponding to the procurement step includes at least: the food procurement information between the supplier and the purchaser and the purchaser's financing information; wherein, the food procurement information includes at least the procurement contract information and actual delivery information between the supplier and the purchaser; the financing information may include at least the financing contract information and financing delivery information between the purchaser and the financial institution.

[0074] Preferably, the actual delivery information may include the supplier's goods delivery information and the purchaser's payment delivery information, and the goods delivery information and payment delivery information include the issuance information and acceptance information of the goods and payment, as well as the actual acceptance certificate of the goods and payment; the participants in the procurement step may also include financial institutions, and the financing delivery information includes the financial institution's fund issuance information and the purchaser's fund acceptance certificate.

[0075] Specifically, the query module 304 is used to respond to the user's query request and retrieve the information of each step in the circulation process of the target food product targeted by the query request;

[0076] Obtain the user's query request; analyze the query request and determine the storage feature information of the target food product targeted by the query request; based on the storage feature information, obtain the stored encrypted step information of the target food product from the blockchain service network; verify the step information; after the verification is completed, display the query step information and its corresponding verification result.

[0077] Preferably, the stored characteristic information may include at least: identifiers such as transaction hash, wallet address or block height;

[0078] Verification methods may include at least: hash verification, Merkle tree verification, and / or multi-node cross-validation;

[0079] Important transaction information in the food supply chain (such as account numbers and amounts involved in fund transfers, or contract details related to transactions) can also be encrypted to improve security. The encrypted information is retrieved from the blockchain service network, verified, and decrypted after verification. The decrypted information and verification results are then displayed. The specific encryption method is not limited here.

[0080] Based on the above system, the specific purchasing and financing information of the early stage of the food supply chain is stored using blockchain technology to ensure the authenticity of the relevant purchasing information. This information is then made available for review by the participants in the purchasing process and authorized participants in other subsequent steps. This allows for supervision of the food procurement process. Blockchain technology is used to prevent the behavior of publicly announcing a higher purchase price while actually purchasing lower-quality ingredients at a lower price for substitution. This greatly improves the authenticity and reliability of the procurement process and ensures food safety in the supply chain from the source. At the same time, by setting the purchaser and the financial institution as participating entities, the financial institution can determine the authenticity of the purchaser's actual transaction. It can also agree to use the sales revenue of subsequent orders for the purchased ingredients as repayment guarantee, and query the subsequent sales steps through this system, further ensuring the repayment of funds. This not only lowers the financing threshold for the purchaser, making it easier for them to obtain financing, but also ensures the security of the financial institution's investment. In addition, by responding to the user's query request through the query module, relevant entities can accurately query the stored step information, which can enable the participants in the food supply chain to form mutual supervision of the upstream and downstream of the supply chain, and realize the whole process traceability of the target food commodity supply chain, fully ensuring food safety and transaction security between all participating entities.

[0081] Figure 4 A schematic flow chart of a method for determining food safety based on information collection according to an embodiment of the present invention is shown;

[0082] like Figure 4As shown, the method includes the following steps:

[0083] Step S401: During the circulation of the target food commodity, environmental image information corresponding to the warehousing steps and logistics transportation steps is collected; the acquired environmental image information is analyzed through artificial intelligence technology to obtain analysis results; based on the analysis results, it is determined whether the environmental image information conforms to the storage method to obtain an environmental judgment result.

[0084] Preferably, if the analysis of any environmental image information in any step information shows that it does not meet the requirements of the storage method, the environmental judgment result will be displayed as there is a risk; conversely, if the analysis of all environmental image information in each step information shows that they all meet the storage method, the environmental judgment result will be displayed as safe.

[0085] Step S402, determine whether the difference between the elapsed time and the shelf life between the purchase step and the current step is greater than a preset time, and obtain a time limit determination result.

[0086] Preferably, if the difference between the expiration date and the expiration date is greater than a preset time period, the expiration determination result is displayed as safe; otherwise, it is displayed as risky. For example, a food ingredient is currently in the storage step, and the sales step and the distribution step typically reserve one day each. If the difference between the expiration date and the expiration date of the previous step is greater than two days, the expiration determination result is safe. If it is less than two days, the expiration determination result is risky. The preset time period can be specifically set according to different food types and the current arrival step, and is not limited here.

[0087] Step S403: determine the food safety status based on the environmental judgment result and / or the deadline judgment result, generate corresponding alarm information according to the food safety status, and send it to the user.

[0088] According to the above method, by acquiring and analyzing environmental images of the warehousing and logistics process, it is determined whether the storage method of food meets the requirements. At the same time, based on the authenticity of the time displayed by the blockchain storage, the time from procurement to the present is accurately determined. In this way, the safety of the food ingredients is scientifically judged according to the shelf life, and an alarm information is generated to inform the user when there is a risk, avoiding improper storage or exceeding the shelf life, and further reducing the risk of food safety problems.

[0104] Specifically, the step information of each step in the target food commodity circulation process is associated with the target food commodity, further including:

[0105] Obtaining a product feature identifier of a target food product;

[0106] Bind the step information of the current step with the product feature identifier of the target ingredient product to complete the association between the step information and the target ingredient product.

[0107] In step S503, the step information associated with the target food product is completed and stored through the blockchain service network.

[0108] Specifically, the step information associated with the target food commodity is stored in the blockchain service network, further including:
