An Efficient Framework for Secure Agriculture Block Supply Chain for Farmer with Crop Yield and Demand Prediction

An entire country's economy, population security, nutrition, and health all depend on its agricultural productivity. In an effort to increase agricultural output, farmers have been adopting new technologies like blockchain and the Internet of Things in recent years. Blockchain has been used to address issues in a variety of industries. Blockchain is being used in agriculture to speed up transaction times and improve food safety. The complex mechanism that keeps agricultural products moving throughout the market is called an agricultural supply chain. Agricultural commercial resources play a crucial role in meeting the demand for agricultural products and preserving their quality and safety as they transport agricultural items across the market. Many existing methods have explored the use of blockchains in the supply chain, although they are unable to enhance the process's overall efficiency. An efficient crop yield prediction and demand prediction system is proposed with secure block chain technology. The proposed system has the following three phases: 1) crop yield prediction system; 2) supply chain process with blockchain; and 3) demand prediction system. The first phase consists of the following steps: dataset collection, preprocessing, feature extraction, feature selection, and training. In the second phase, farmers, distributors, retailers, and consumers are involved. Finally, for demand prediction, pre-processing, feature extraction, feature reduction, and prediction are carried out. All three phases are linked to a blockchain and securely stored in the cloud.
