Research Area: Blockchain Technology
Blockchain and the Internet of Things (IoT) are separately regarded as highly capable popular technologies. Blockchain is a database used for decentralized transaction purposes. It provides novel directions to store and manage data, whereas IoT relates to the propagation of linked machines by providing information through the Internet. A mixture of Blockchain and the IoT appears hopeful, even though blockchain requires real-time data application, and IoT describes processes to store and manage information overloads safely and proficiently. The technology is significant to the manufacturing business, experiencing a digital revolution by incorporating equipment, developments, and data, leading to the Industrial IoT (IIoT). Such a combination of IIoT and blockchain is termed Blockchain for Industrial Internet of Things (BIIoT). The paper gives a detailed survey on BIIoT and discusses all relevant aspects of this novel concept. Firstly, IoT as a concept has been explored briefly, and relevant threats to IoT has been investigated. Furthermore, the domain of IIoT and the relevant challenges to IIoT is discussed. Additionally, an overview of blockchain technology is presented. Subsequently, a combination of IIoT and blockchain is explored, and the BIIoT structural design proposal is submitted. Finally, issues related to the use of IIoT with blockchain for industrial applications of BIIoT is explored. Thus, all relevant open research directions in Blockchain and IIoT are summarized in this paper. This survey shows that the proposed BIIoT is used to develop a redundant, traceable, and secure complex interconnected IIoT environment. Furthermore, the BIIoT system enables us to communicate with each other without the need for a trusted intermediary in a decentralized, unreliable, peer-to-peer network.
