Designing A Secure Food Supply Chain System using Blockchain in Agricultural IoT

One of the important areas of research that needs a global attention is the agribusiness and its network of supply chains. Internet of Things (IoT) based smart models of this system facilitates all the participants in several means to make the life easy. Blockchain can play an inevitable role to enhance the security, to protect the end users from the potential health risks, and to avoid the financial frauds. Therefore, some blockchain based food supply systems have been developed to provide the transparency and immutability. However, the security of such existing systems can be optimized with improved integrity, confidentiality, latency, authentication delay, throughput, and computational time. In this direction, a blockchain and IoT enabled secure and smart agricultural food supply chain system has been devised and presented in this paper. The suggested model performs better than the current plans in terms of trust, authentication delay, computational time, and throughput.
