Blockchain based tomato supply chain management

Supply chain in agriculture field is very important as the cultivated goods are sensitive for time and temperature. Most of the time, middlemen act as the price-fixing authorities. The farmer’s profit declines as the number of people increases. Additionally, there is no provision for tracking the status of the farming goods throughout transportation. Tomatoes are one of the many products that are time, temperature, and container sensitive. These parameters could be tracked by a centralized system, which would be more advantageous. Blockchain is a distributed database providing tamper proof storage of data. The management of the tomato supply chain based on blockchain is suggested in this research. Customers can use this method to learn how the produce is grown and how the shipping process works. Here, the farmer uses the smart contract to periodically update the blockchain with the crop status. The farmer grows it and sells it once it is ripe for cultivation. As a result, the proposed system enables the customer to be fully informed about the crop and commodities. Additionally, it helps the farmer keep track of their products and maximize their yield’s profit.
