SURVEY ON SUPPLY CHAIN MANAGEMENT USING BLOCKCHAIN TECHNOLOGY

Abstract

With the advancement of blockchain in every field, it is also used in the agri-food supply chain. As the food supply chain is such a network where no one knows from where and what quality of food is transported and how long it takes to reach its destination. The blockchain helps to keep track of the complete chain with the help of distributed ledger. Each transaction, the quality of food, and the time required to reach its destination are saved. Supply chain management carries out all the processes from raw material to the final product. The supply chain is divided into several stages from the farmer to the customer. Although the blockchain food supply chain provides immutability of data and records in the network. In the proposed system, all transactions are written to blockchain which ultimately up-loads the data to the Interplanetary File Storage System (IPFS), along with the auction system for the buying and selling of the food items directly from the farmer. The storage system returns a hash of the data which is stored on the blockchain and ensures an efficient, secure, and reliable solution. Our system provides smart contracts and their algorithms to show the interaction of entities in the system.
