Blockchain Enabled Industrial Internet of Things Technology

Abstract

The emerging blockchain technology shows promising potential to enhance industrial systems and the Internet of things (IoT) by providing applications with redundancy, immutable storage, and encryption. In the past few years, many more applications in industrial IoT (IIoT) have emerged and the blockchain technologies have attracted huge amounts of attention from both industrial and academic researchers. In this paper, we address the integration of blockchain and IIoT from the industrial prospective. A blockchain-enabled IIoT framework is introduced and involved fundamental techniques are presented. Moreover, the main applications and key challenges are addressed. A comprehensive analysis for the most recent research trends and open issues is provided associated with the blockchain-enabled IIoT.
