Abstract

This chapter explores the critical intersection of consensus mechanisms and performance metrics in blockchain systems for the Internet of Things (IoT). As IoT networks expand, the demand for scalable, efficient, and secure blockchain solutions intensifies. This chapter evaluates the trade-offs between energy efficiency, latency, scalability, and security within IoT-integrated blockchain frameworks. Key consensus protocols such as PoW, Proof of Stake (PoS), and Delegated DPoS) are analyzed for their applicability in IoT environments, highlighting their impact on transaction speed, resource utilization, and network resilience. Hybrid consensus models are examined for their potential to balance performance with robust security. The chapter also provides real-world case studies that benchmark latency and energy efficiency, offering insights into the practical challenges and opportunities for IoT-based blockchain applications. Key findings contribute to the ongoing development of optimized blockchain solutions for IoT networks.
