Description of Drawings
[0034] Figure 1 is a flow diagram of the blockchain-based agricultural service and intelligent contract management method in the embodiment of the invention.
[0035] The realization of the purpose, functional features and advantages of the invention will be further illustrated in conjunction with the embodiments and with reference to the drawings.
Detailed Description of the Presently Preferred Embodiments
[0036] The technical solutions of the invention will be illustrated in detail below in combination with the drawings and specific embodiments, so as to understand the essence of the invention more distinctly and intuitively.
[0037] Referring to Figure 1, the embodiment provides a blockchain-based agricultural service and intelligent contract management method, which is used to intelligently manage the cooperative relationship between investors and farmers providing agricultural services. The method mainly comprises:
[0038] Si: Establish an agricultural service chain, and issue agricultural services with blockchain;
[0039] S2: Copy the agricultural service chain to theblockchain node;
[0040] S3: Establish a service contract block, and construct a service contract between farmers and investors with blockchain;
[0041] S4: Copy the service contract block to a blockchain node;
[0042] S5: Store and distribute the service contract block.
[0043] Through the above methods, farmers can rent the land their own to investors, and investors can rent their land. On the basis of taking certain risks, they can obtain a certain income when harvesting agricultural products. Investors can participate in management and introduce advanced agricultural management methods such as weather prediction mechanism, so as to increase the profits of investors and farmers.
[0044] In Step S, the steps for establishing an agricultural service chain specifically comprise:
[0045] Establish the same number of agricultural service chains according to the number of land divided, and each land corresponds to one of the agricultural service chains and is associated as one chain in the blockchain.
[0046] And the steps for issuing agricultural services with blockchain specifically comprise:
[0047] Set an appropriate agricultural cycle according to the planting or cultivating type of the land, and issue agricultural services within the agricultural cycle.
[0048] The planting type refers to the type of crops planted in the plough land, such as rice, wheat, rape, sorghum, etc. The type of the cultivated land, such as fish, shrimp, sheep, cattle, pig, etc.
[0049] In Step S3, the steps for building a service contract block and constructing a service contract between farmers and investors with blockchain specifically comprise:
[0050] Automatically construct the service contract between farmers and investors according to the agricultural services purchased by investors, and generate the service contract block with service contracts, and each service contract is associated as one block in the blockchain.
[0051] According to the above agricultural services purchased by investors, the steps for automatically constructing the service contract between farmers and investors further comprise:
[0052] Automatically construct the corresponding service contract according to the weather forecast level provided and the risk level selected by investors, so as to distribute the income to the investors according to the service contract.
[0053] Generally speaking, the more accurate the weather forecast, the higher the income that investors should receive. Similarly, the higher the risk level selected, the higher the income system should be. Therefore, when signing a service contract, investors should select an appropriate service contract template according to their own strengths, including the ability to predict the weather and the ability to take risks, etc., so as to construct a service contract in accordance with the needs of all parties.
[0054] For example, when calculating the investor's income, assuming that the risk system selected by the investor is k and the weather forecast index is x, then the final income is calculated according to the following formula:
[0055] y=kx+b, where b is the basic income value.
[0056] When introducing the weather forecast index, it is necessary to rank the accuracy of the forecast first, that is, the more accurate the weather (including temperature and humidity) forecast, then the higher the investor's ranking, and the higher the forecast index x. As for the functional relationship between the accuracy of the forecast and the forecast index x, it can be determined by the investors and farmers through consultation, or by a third-party authoritative risk control institution.
[0057] When calculating the income, the land area can be calculated in in 2 , and the unit output value can also be calculated in in 2 . Combined with the planting or cultivating type, the value of the income will be quantified finally, so that it is convenient to calculate the respective income value of investors and farmers.
[0058] In Step S5, the steps for storing and distributing the service contract block specifically comprise:
[0059] Each node stores all the generated service contracts after copying the service contract block to the blockchain node, and each farmer and investor holds multiple service contracts in the blockchain.
[0060] In addition, the method also configures the following parameters for the service contract, so as to distribute the income to the investors according to the parameters:
[0061] The service contract corresponds to the output of agricultural products in plough land or cultivated land;
[0062] The actual market price of the agricultural products;
[0063] The food quality of the agricultural products, and/or
[0064] The plant growth rate in the plough land or the animal growth rate in the cultivated land.
[0065] Of course, in order to encourage farmers to provide better agricultural services, it is not excluded to add other parameters or other solutions that can increase farmers' income, for example, the total expected income is stipulated in the service contract, when the amount is exceeded, farmers are allowed to share the surplus of the excess part.
[0066] Meanwhile, the public investment pool block can be set up, and investors can add more investment funds to the public investment pool. In addition to storing and managing investors' funds, the government, enterprises or relevant organizations can also invest funds to attract more investors to invest in agricultural services, which is conducive to the development of agricultural technology and the sharing of agricultural resources.
[0067] Cameras and weather monitoring systems can also be installed on plough land or cultivated land to provide investors with real-time current weather conditions, so that investors can provide more accurate weather forecast results.
[0068] Preferably, according to the agricultural services purchased by investors, the steps for automatically constructing the service contract between farmers and investors further comprise:
[0069] Encrypt the service contract.
[0070] After encrypting the service contract, copy the service contract to each node with the characteristics of blockchain distributed storage, so as to realize the distributed storage of the service contract.
[0071] Further, after the steps for storing and distributing the service contract block, it also comprises the following step:
[0072] S6: Maintain the service contract block.
[0073] Meanwhile, the steps for maintaining the service contract block specifically comprise:
[0074] When the service contract blocks are larger than ten, ten farmers are randomly selected to maintain all the service contract blocks in the blockchain.
[0075] When the number of service contract blocks is large, it is too complicated to use the method of each farmer maintaining his/her own service contract block separately, which is not conducive to simplifying the cooperation procedure. Therefore, a certain number of farmers (ten in this embodiment) are randomly selected to uniformly maintain all service contracts in the blockchain, which not only saves network resources, but also has high efficiency. Reasonable maintenance can improve their agricultural service level and increase exposure, so as to attract more investors to cooperate with them and bring more benefits to farmers.
[0076] In other embodiments, the agricultural service of the invention can also be performed in a virtual manner, and the income of agricultural service can be calculated by referring to the harvest date price of individual agricultural products. The virtual agricultural service forecast can put part of the service fee into the agricultural development fund. The agricultural service and intelligent contract management method of the invention can generate an agricultural service system in combination with the block chain technology. In the initial stage of the development of the system, it is conducive to the rapid promotion of the system with the aid of the agricultural development fund.
[0077] In conclusion, the invention uses the blockchain technology, and combines the investment characteristics between farmers and investors to construct the agricultural service chain and service contract block, and embed them in the block chain, which realizes the comprehensive intelligent management of the agricultural services provided by farmers and the service contracts signed between farmers and investors, effectively simplifies the cooperation procedure between farmers and investors, reduces the cooperation cost, is conducive to promoting the research on agricultural technology and introducing capital into agriculture, and can significantly improve the income level of farmers.
[0078] The above is only a preferred embodiment of the invention, and does not limit its patent scope. Any transformation of equivalent structure or equivalent process made by using the contents of the descriptions and the drawings of the invention, which is directly or indirectly applied in other related technical fields, shall be similarly included in the scope of patent protection of the invention.
