Abstract
The integration of Blockchain technology with the Internet of Things (IoT) presents a transformative approach to addressing critical challenges in security, data integrity, and automation. This paper explores the synergies between these technologies, proposing a framework that leverages the decentralized and immutable nature of Blockchain to enhance IoT ecosystems. By eliminating single points of failure, Blockchain ensures robust security for IoT devices and networks. Furthermore, its transparent and tamper-resistant data structure guarantees the integrity of data exchanged across IoT systems. The study also examines how smart contracts can automate processes within IoT environments, enabling real-time decision-making and reducing human intervention. Practical use cases, such as secure supply chain management, automated healthcare systems, and industrial IoT applications, are discussed to illustrate the effectiveness of the proposed framework. The results demonstrate significant improvements in system resilience, trustworthiness, and operational efficiency, highlighting the potential of Blockchain-enabled IoT to revolutionize diverse industries.
