The rapid expansion of IoT systems significantly scales up the number, heterogeneity, and vulnerability of connected devices, making the IoT ecosystem an attractive target for cyberattacks. Traditional security mechanisms based on a centralized authority fail to provide scalability, transparency, and real-time threat mitigation in such dynamic environments. Although blockchain technology offers decentralisation, immutability, and trust, its direct adaptation is not feasible in IoT systems due to the significant computational overhead and resource constraints. Similarly, AI enables intelligent threat detection but lacks secure data integrity and trustworthy coordination in a standalone deployment. This paper proposes the Smart Chain AI-driven blockchain framework to enhance IoT security in a scalable and resource-efficient manner. Smart Chain integrates lightweight blockchain mechanisms with AI-based intelligence to offer secure device authentication, dynamic access control, adaptive consensus, and real-time anomaly detection. The proposed AI-driven blockchain framework leverages AI to analyze IoT behavioural patterns, optimize consensus selection, and automate security responses using smart contracts, while blockchain ensures data integrity, transparency, and tamper-resistant logging. Unlike existing solutions that tend to consider AI and blockchain as two orthogonal components, Smart Chain presents a unified architecture tailored for resource-constrained IoT environments. In this regard, the proposed framework can improve security, trust management, and system resilience with minimal computational and energy overhead. Smart Chain demonstrates that the synergistic integration of AI with blockchain can help overcome current limitations in IoT security, therefore providing a practical and extensible solution for next-generation secure IoT ecosystems.
