Internet of Things and Industrial IoT Using Blockchain: A systematic review

Abstract: IoT privacy risks and security vulnerabilities are emerging from a lack of basic security technology, despite the IoT's rapid development and widespread attention in academia and industry. The blockchain technique was proposed as a decentralized and distributed approach to guarantee security requirements and encourage the growth of the IoT and IIoT because of its decentralization and information disclosure. First, we briefly overview blockchain's overall design and highlight its most important features before discussing the security measures needed to fully realize the Internet of Things and the Fourth Industrial Revolution. Then, we delve into how blockchain's security features can be utilized by the IoT for Industry 4.0. To promote the features and benefits of the blockchain technique on IoT and IIoT platforms, we explain the most important blockchain-based IoT applications. Finally, suggestions are made to help future blockchain researchers and coders get started.
