Dear Colleagues,

In recent times, the technological spheres of Blockchain and the Internet of Things (IoT) have emerged as significant disruptors, with both leading a wave of innovation in their respective domains. Their intersection is now poised to redefine our approach to digital infrastructure and interconnected systems.

Blockchain, known for its decentralized and secure architecture, has evolved beyond its cryptocurrency roots to become a foundational technology for various sectors, ensuring data integrity and trust in digital transactions. Its adoption in areas like smart city development, energy management, etc., highlights its versatility and capacity to address complex data challenges. Conversely, IoT has been instrumental in driving the connected world, offering real-time data collection, automation, and enhanced operational efficiency across diverse industries.

The integration of IoT with Blockchain opens up new avenues for secure, transparent, and reliable data exchange in interconnected systems, such as decentralized IoT networks secured by Blockchain, improved data privacy in IoT devices, and smart contracts facilitating autonomous IoT operations. However, this integration also brings forth unique challenges related to scalability, interoperability, and energy efficiency that need to be addressed for optimal utilization.

This Special Issue aims to explore the synergies between Blockchain and IoT, highlighting the innovations at their nexus, understanding the obstacles in their joint application, and envisioning a future where these technologies cohesively work to create advanced, secure, and efficient systems.
