Blockchain System with Credit-Based Consensus Mechanism for Industrial Internet of Things: An Application of Industry 4.0 Vasantha, B. Bhavana, K. Kavya, K. Varshini, M. Industrial Internet of Things Blockchain Decentralized System Consensus Mechanism The convergence of Blockchain technology with the Industrial Internet of Things (IIoT) has emerged as a strategic response to the challenges inherent in traditional industrial systems. In the backdrop of Industry 4.0, where the optimization of industrial processes relies heavily on data-driven decision- making, there is a pressing need for a robust and secure infrastructure. The primary issues stem from the vulnerabilities of centralized systems, including data security risks, lack of transparency, and susceptibility to unauthorized access. To address these challenges, a proposed solution involves the implementation of a Blockchain system tailored specifically for industrial applications. By leveraging the decentralized and tamper-resistant nature of Blockchain, this system ensures the security and immutability of data within the IIoT ecosystem. Furthermore, the introduction of a Credit-Based Consensus Mechanism adds an innovative layer to the solution, where participants gain influence or voting power based on their reputation or "credit" within the network. The significance of this approach lies in its capacity to enhance security, reliability, and trust in IIoT operations. The decentralized architecture mitigates the risks associated with single points of failure, fostering a more reliable IIoT system. Moreover, the credit-based consensus mechanism promotes trust among participants, facilitating collaboration and information sharing in the dynamic landscape of Industry 4.0. In essence, the integration of Blockchain and the credit-based consensus mechanism presents a comprehensive solution to fortify the Industrial Internet of Things, addressing the shortcomings of traditional centralized systems and ensuring a secure and transparent foundation for Industry 4.0 advancements. 2025-04-22T10:33:55Z 2025-04-22T10:33:55Z 2024-12-31 journal article B.
