Integration of Blockchain& IoT in Precision Farming: Exploration, Scope and Security Challenges

Internet of things (IoT) plays a major role in every field. It helps in transforming the way with the use of sensors, edge devices and its infrastructure. As sensors are major source of information gathering which is stored on the cloud and relevant information is being retrieved. Information is passed at various levels of IoT ecosystem, which takes security into consideration. With the growth of interconnected devices, data security is becoming increasingly complex. The necessity arising for building a secure and smart structure leads in combining blockchain technology with IoT based system in precision agriculture. With the use of blockchain, traditional methods utilized for collecting and sharing agriculture data are replaced with transparent, reliable and decentralized data storage methods. This combined approach helps us in maintaining an autonomous precise agriculture system and managing in more secure and optimized ways. This paper presents a comprehensive approach on highlighting the importance of integrating blockchain technology with smart agriculture. This paper also proposes novel approach to blockchain models which are used as alternate solutions for challenges faced by IoT based smart agriculture. Various sub sectors like food supply chain, livestock grazing, and crops overseeing are also managed using blockchain platform. Later section of the paper focuses on open challenges and issues while developing blockchain based IoT system used in precision farming.
