The rapid growth of Internet of Things (IoT) networks has increased security vulnerabilities due to their distributed, resource-constrained, and heterogeneous nature. Traditional intrusion detection systems (IDS) often face limitations related to scalability, data integrity, and centralized trust. This review presents a comprehensive analysis of blockchain-based intrusion detection systems for IoT networks, highlighting how blockchain technology enhances security through decentralization, immutability, and transparent data sharing. Existing studies integrating blockchain with machine learning and deep learning–based IDS are examined, along with commonly used architectures, consensus mechanisms, and performance metrics. The review also discusses key challenges such as computational overhead, latency, and energy consumption. Finally, open research issues and future directions are identified to support the development of secure, efficient, and scalable blockchain-enabled IDS solutions for IoT environments.
