Agri Food Supply Chain Using Ethereum Smart Contract

Abstract

The supply chains of the contemporary world are changing to become automated and extremely complicated networks, gaining many advantages. Due to this, customers are more concerned about the quality of food products. It is not easy to ensure data integrity across the supply chain network, however, In contrast to decentralized supply networks, conventional ones are centred and rely on a third party for trade. As a result, there is a lack of transparency, accountability, and audibility in centralized systems. We have suggested a comprehensive solution for the Agri-Food supply chain using Ethereum. It brings together blockchain and smart contracts, which are both linked to Ethereum. However, the inherent immutability of blockchain still does not adequately address several supply chain management issues, such as the trustworthiness of the participating entities, accountability of the trade process, and product traceability. To fulfil these needs, a trusted system is required that guarantees traceability, trust, and delivery mechanism for the supply chain in the Agri-Food industry. The suggested system uses blockchain technology to keep track of all transactions, and after that, the data is uploaded to Interplanetary File Storage System (IPFS). A hash of the data is returned to the storage system, and it is made efficient, safe, and trustworthy via the use of blockchain. The interaction of entities is shown with the help of smart contracts and their algorithms in our system. The findings provided in this study also include simulations and evaluation of smart contracts along with the assessment of security and vulnerability.
