Blockchain based Authentication for Internet of Things Devices based on Smart Farming

Farmers and other users who are using smart farming technology can access agricultural data through a unified blockchain-based platform. In this way, the transparency, anonymity, and traceability added by the blocks in the blockchain ensure that the correct data can be used when it is needed or in the future. It is necessary to authenticate with the original owner of the cattle to buy or sell cattle, and in some cases, governments also want to use that data in case of theft or accident. With its inherent characteristics, blockchain offers a promising approach for decentralized authentication in IoT networks. To provide efficient, decentralized mutual authentication and privacy protection for IoT users. This study examines the efficient, secure, and decentralized store of information of blockchain. This study also discusses on the cattle farmers who buy and sell animals, authenticate the owner of the cattle, and ensures scalability, interoperability, cost-effectiveness, and simplicity that help farmers to use blockchain-based authentication for their IoT devices.
