Blockchain of Things: Benefits, Challenges and Future Directions

As Internet of Things (IoT) technologies become increasingly integrated into our daily lives through a multitude of Internet-enabled devices, the efficient, secure, and cost-effective management of the vast amount of data generated by these devices poses a significant challenge. Blockchain has recently emerged as a promising technique to address this challenge by providing a means to establish trust without relying on a trusted third party. The convergence of blockchain and IoT presents a transformative opportunity to establish a secure and robust mechanism for managing the data generated by IoT devices. It is recognized as the essential missing link for enabling IoT devices to fully harness their benefits. This Special Issue delves into a diverse range of IoT-enabled blockchain-driven solutions that leverage the integration of IoT and blockchain technologies, aiming to explore and advance the intersection of these two innovative technologies.
For this Special Issue, we received 19 papers in total, and 11 of them were accepted and published. The authors presented some novel ideas, frameworks, and smart contract vulnerability detection methods to solve many real-world problems. These advanced models not only offer tailored solutions but also contribute significantly to increased efficiency, heightened security, and improved efficiency, highlighting the transformative potential of the integration of IoT and blockchain technology. We extend our heartfelt gratitude to all authors for their valuable contributions to this field.
