A Study on Smart Agriculture Utilizing IoT using Block Chain in Smart Contract

All sectors have been updated with new technologies, but India's agriculture, especially Tamil Nadu, is still lagging behind. Third-party interventions are so high that reduced food chain traceability, increased costs, and security issues affect smallholder’s farmer and provide consumers with sufficient knowledge to buy products at low prices. Use of blockchain technology in smart contracts combined with the Internet of Things. This paper analyses literature studies that focus primarily on food chain traceability and explores aspects of cost analysis, time consumption, and security. Therefore, these challenges are blockchain technology in smart contracts, which is being monitored by smallholder’s farmer and consumers are also benefiting from it.
