Blockchain Based Supply Chain System: A Case Study of Agriculture

Effective supply chain is important for all the stake holders. In recent years use of ICT based solutions have increased rapidly. Cloud based systems improved the working and are a cost-effective solution. Still, the whole supply chain with multiple intermediaries being in play is affected by the problem of introducing counterfeit agriculture products which have been of major concern. There is a need for a technology-based solution to prevent such issues and identify culprits. This paper proposed a blockchain based agriculture supply chain assimilated with decentralized application into the various nodes of the supply chain. To perform actions on a product or raw material, certain conditions associated with these products should be met. The actions performed on a product will be redirected to smart contracts associated with these products and transactions of this product will be stored in respective transaction contract. The data consisting of different product details and the backtracking of ownership records correspond to an improvement in dependability, responsibility, and better traceability. This improvement is made possible by using a signature-based event, request-response verification mechanism, and mandatory data updates every time significant computer in the agriculture supply chain.
