Abstract
The rapid evolution of Industry 4.0 has catalyzed the integration of advanced technologies to ensure secure, efficient, and scalable industrial systems. This study introduces a Hybrid Blockchain-Enabled IoT System tailored for secured Industry 4.0 environments. By combining the decentralized and immutable nature of blockchain technology with the real-time data acquisition and analytics capabilities of the Internet of Things (IoT), the proposed framework addresses critical challenges such as data integrity, cybersecurity, and system scalability. The IoT devices serve as edge nodes, collecting and transmitting data securely through a private blockchain network to mitigate risks of tampering and unauthorized access. The system leverages a hybrid consensus mechanism to balance computational efficiency with security. For evaluation, real-time industrial data, including sensor readings, machine states, and environmental parameters, were utilized to assess the system's performance in various industrial scenarios. The results demonstrate robust security, low latency, and seamless interoperability across connected devices. Compared to traditional centralized models, the proposed system offers superior resilience against cyber threats while maintaining high throughput and reliability. This research underscores the potential of merging blockchain and IoT technologies to pioneer secure and efficient Industry 4.0 systems, paving the way for sustainable and trustworthy industrial automation.
