Abstract

The invention relates to the technical field of block chains, in particular to an agricultural product supply chain system based on a smart contract, and the system comprises: a data collection station which collects planting data of a planting area and stores the planting data; a transportation tracker which is used for collecting and storing transportation data; a reservation server which is used for displaying planting data of crops planted in a current planting area, allowing a purchaser to browse the planting data of the crops to reserve agricultural products and generate an intelligent contract; a goods inspection server which is used for installing a transportation tracker on a transportation vehicle and transporting the transportation vehicle to an appointed collection farmer's market; and a smart contract which is verified by using a planting verification model and a transportation verification model, judging that the agricultural products are received if the verification is passed, , and transferring corresponding tokens to the virtual account of the farmer according to the warehousing weight. The system has the substantive effects that the supply relation is established as soon as possible, so that the transportation time of the agricultural products is greatly shortened, and the transportation loss of the agricultural products is reduced.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to an agricultural product supply chain system based on smart contracts. Background technique [0002] At present, my country's agricultural product supply chain has the characteristics of a long side. Fruit and vegetable products go through four or five links from the farmers who grow them to the consumers. The circulation link not only leads to the lengthening of the transportation time of fruits and vegetables, but also leads to the increase of losses. In addition, there are more or less price increases in each link, resulting in the current supply chain of agricultural products with high prices at the consumer end and low prices at the production end. Citizens bear higher vegetable prices, but it is difficult for farmers to increase their income. In the intermediate circulation link, due to the loss of transportation and storage, the intermediate wholesalers also bear a ...
