abstract = {The rapid expansion of the Internet of Things (IoT) has introduced severe security vulnerabilities due to its reliance on centralized architectures and resource-constrained devices. To address these limitations, this paper proposes a hybrid, lightweight framework converging Blockchain and Machine Learning (ML) to inherently secure IoT ecosystems. The system employs an Ethereum-based distributed ledger (via Smart Contracts) to ensure immutable data logging and decentralized access control. Simultaneously, an edge-based ML engine utilizes Isolation Forests for real-time, multidimensional anomaly detection against sensor deviations and power-profiling cyber-attacks. By linking this ML-based intrusion detection directly with a blockchain-driven dynamic device trust scoring mechanism, the framework establishes an automated, self-healing network. Experimental simulations establish that this integrated approach successfully mitigates data tampering and Sybil attacks with minimal edge computational overhead, delivering a robust, scalable, and decentralized security architecture suitable for modern IoT deployments.},
