Abstract The rapid growth of the Internet of Things (IoT) has introduced a large number of resource-constrained devices that operate with limited processing power, storage capacity, an‎d energy. These limitations make traditional trust management an‎d security mechanisms ineffective, particularly in large-scale an‎d dynamic IoT environments. In recent years, blockchain technology has emerged as a promising solution for decentralized trust management due to its immutability, transparency, an‎d resistance to single points of failure. This paper presents a comprehensive review of blockchain-based frameworks for trust management in resource-constrained IoT devices. Existing studies are systematically analyzed an‎d classified based on key aspects such as trust modeling approaches, lightweight blockchain design, consensus mechanisms, scalability, security features, an‎d real-world performance considerations. The review highlights how lightweight an‎d hierarchical blockchain architectures, optimized consensus protocols, an‎d edge-assisted processing are employed to address IoT constraints. Furthermore, critical challenges related to scalability, network latency, an‎d energy efficiency are discussed in detail. By identifying strengths, limitations, an‎d research gaps in current solutions, this study provides a structured analytical perspective that can guide future research toward the development of scalable, secure, an‎d practical blockchain-enabled trust management frameworks for next-generation IoT systems.
