Blockchain-Empowered Multiagent Systems: Advancing IoT Security and Transaction Efficiency

The rapid growth and escalating complexity of the Internet of Things (IoT) necessitate meticulous attention to ensure efficient and secure transactions among various autonomous components. To address this critical issue, this study proposes the integration of multiagent systems (MASs) and blockchain technology within the IoT domain. Uniquely, our approach employs smart contracts to manage exchanges between autonomous entities, thereby offering enhanced security, transparency, and reliability. The study introduces a set of innovative algorithms that regulate agent activities, such as creating blocks, sharing information, and conducting rating processes. Additionally, it provides a detailed analysis of their privacy and security aspects. Compared to traditional multiagent frameworks, empirical evidence demonstrates significant improvements in efficiency, adaptability, and scalability. This scholarly effort lays a robust foundation for further investigations into applying blockchain to enhance MASs, potentially paving the way for more sophisticated and context-specific strategies across various IoT fields.
