Embodiment 1

[0024] A vegetable supply system based on block chain 60 technology, please refer to the attached figure 1 , including: several planting data stations 20, deployed in the production area, connected to several greenhouses 10 of several farmers, assigning greenhouse numbers to the greenhouses 10, associating the greenhouse numbers with farmers, collecting and storing the planting data of the greenhouses 10, The planting data includes type, area, geographic location, planting time and growth environment data, and the planting data is associated with the greenhouse number, and the planting data station 20 stores the collected planting data through the block chain 60; the demand release server 30, and plant data station 20 connection, please refer to the attached figure 2 , the vegetable demand side publishes the demand list on the demand publishing server 30, the demand list includes the type, demand date, demand quantity, quality rating requirements and delivery address 50, and ...

Embodiment 2

[0033] A vegetable supply system based on blockchain 60 technology. This embodiment further improves the data storage method of the planting data station 20 on the basis of the first embodiment. Please refer to the attached Figure 5 The planting data station 20 establishes a storage track 26 for each planting area, and the storage track 26 adopts a sequential storage structure. The planting data station 20 periodically stores the planting data into the storage track 26, and the initial end of the storage track 26 establishes an initial storage point 22 , the initial storage point 22 stores a random number, the random number is used as the initial associated hash value 21, the storage point 22 occupies a storage space of a preset length, and the planting data station 20 periodically creates a new storage for the storage rail 26 Attestation point 22, extract the hash value of the planting data between the latest two attestation points 22 and store it at attestation point 22, an...

Abstract

The invention relates to the technical field of block chains, in particular to a vegetable supply system based on a block chain technology, and the system comprises: a plurality of planting data stations which collect and store planting data of a greenhouse, wherein the planting data stations carry out the evidence storage of the collected planting data through a block chain; and a demand issuing server, wherein a vegetable demand side issues a demand list on the demand issuing server, an intelligent contract is generated for the order, the demand side transfers a plurality of tokens to an intelligent contract account address, and a farmer harvests agricultural products and transports the agricultural products to a delivery address according to a demand date, and after arrival, the demand side calls the corresponding planting data through the demand publishing server for verification, and if the verification of the verification model is passed, the intelligent contract transfers the corresponding token to the farmer household account. The system has the substantive effects that the vegetable supply contract is matched through the demand publishing server, the intelligent contract is constructed, the vegetables are supplied on time, the planning of vegetable supply is improved, and the arrangement of subsequent production is facilitated.

Description

technical field [0001] The invention relates to the technical field of blockchain, in particular to a vegetable supply system based on blockchain technology. Background technique [0002] The storage period of vegetables is short. For example, eggplant can be stored in a cool place for 3 to 4 days. Green leafy vegetables such as celery / chrysanthemum can be kept fresh for 3 to 4 days when soaked in water. Tomatoes can be stored in cold storage for about 10 days. After being harvested from the planting area, it needs to be delivered to consumers as soon as possible, otherwise it will lead to large transportation and storage losses of agricultural products. According to statistics, the rot rate of some agricultural products can reach 20%-30%, which has caused great losses to agricultural products. The reason is that the current supply chain of agricultural products is relatively long, and the information on the supply side and the demand side is not smooth. The intermediate c...
