Abstract
The integration of blockchain with Internet of Things (IoT) technologies has opened new avenues for secure, decentralized smart home automation. This paper presents a novel access-control framework using Binance Smart Chain (BSC) to ensure verifiable, low-latency device interaction without embedding consensus or token economics within the smart contract itself. The contract enforces permissions using application-level logic deployed on a public blockchain, enabling cost-efficient and tamper-proof control over IoT actuators. Functional testing via Foundry and transaction-level evaluation on BSC confirmed the system’s performance, with actuation delays averaging 3–4 seconds and costs consistently below $0.02 per interaction. Security validation through adversarial simulations demonstrated resistance against unauthorized access, replay attacks, and privilege misuse. Compared to Ethereum, Hyperledger Fabric, and IOTA, the proposed framework delivers a strong balance of scalability, affordability, and ease of deployment. The discussion explores future improvements, including role-based and attribute-based access control (RBAC and ABAC), sidechain integration, and zero-knowledge proofs to further optimize security, scalability, and user-centric automation. This work contributes a practical blueprint for secure, blockchain-driven smart home systems applicable to residential and enterprise IoT infrastructures.
