Blockchain-based Agri-Food Supply Chain: A Complete Solution
Abstract and Figures
Supply chains are evolving into automated and highly complex networks and are becoming an important source of potential benefits in the modern world. However, it is challenging to track the provenance of data and maintain traceability throughout the network. Consumers are now more interested in food’s and product’s quality. The traditional supply chains are centralized and they depend on third party for trading. The traditional centralized systems lack transparency, accountability and auditability. In our proposed solution, we have presented a complete 1 solution for blockchain-based Agriculture and Food (Agri-Food) supply chain. It leverages the key features of blockchain and smart contracts deployed over ethereum blockchain network. Although blockchain provides an immutable network for supply chain events, it still lacks in solving major problems like accountability, traceability and credibility of supply chain events. Therefore, there is a need of reliable system that ensures traceability, trust, trading and delivery mechanism in Agri-Food supply chain. All transactions in the proposed scheme are uploaded to blockhain; while, it ultimately uploads the data to Interplanetry File Storage System (IPFS). The storage system returns a hash of the data which is stored on blockchain and ensures efficient, secure and reliable solution. Futhermore, simulations and evaluation of smart contracts along with the secuirty and vulnerability analyses are also presented in this work.
