Exploring the Synergies between Blockchain and Internet of Things (IoT) Technologies: A Review of Current Applications and Future Potentials

The convergence of Blockchain and Internet of Things (IoT) technologies has garnered significant attention due to its potential to revolutionize various industries. This paper presents a comprehensive review of the current state of applications and explores the future potentials arising from the synergistic integration of Blockchain and IoT. By combining the tamper-resistant and decentralized nature of Blockchain with the ubiquity and data-sharing capabilities of IoT, novel solutions have emerged in areas such as supply chain management, healthcare, energy, and more. We analyze prominent use cases that leverage this convergence, highlighting the enhanced security, transparency, and efficiency benefits they offer. Moreover, the paper identifies key challenges such as scalability, interoperability, and resource constraints that need to be addressed for widespread adoption. Looking ahead, the paper envisions promising directions for research and development, including hybrid approaches, consensus mechanisms tailored for IoT, and privacy-preserving solutions. As both technologies continue to evolve, this review underscores the transformative potential of their synergy, paving the way for a new era of interconnected, secure, and efficient systems
