The rapid expansion of domotics, or smart home systems, has transformed modern living through automation, remote monitoring, and intelligent control of household devices. However, as these systems increasingly rely on interconnected devices and centralized platforms, concerns regarding data privacy, security vulnerabilities, and single points of failure have become more pronounced. This paper explores the integration of blockchain technology into domotics systems as a solution to these challenges, offering a decentralized and tamper-resistant framework for enhancing security and operational autonomy.
By utilizing blockchain’s distributed ledger mechanism, smart home environments can ensure trustworthy device communication, transparent data logging, and robust user authentication without dependence on centralized servers. The study analyzes how smart contracts can automate home functions—such as lighting, climate control, and access management—while maintaining user-defined rules in a secure and verifiable manner. Furthermore, the implementation of blockchain introduces improved data integrity and privacy, ensuring that sensitive household data remains encrypted and accessible only to authorized entities.
The paper presents a prototype model combining IoT-enabled smart devices with a blockchain backend to demonstrate practical feasibility and performance metrics, including latency, energy consumption, and system resilience. It also discusses scalability concerns and evaluates potential trade-offs between decentralization and resource efficiency.
Ultimately, this research highlights blockchain as a transformative enabler in the evolution of secure, efficient, and user-centric domotics systems, paving the way for more resilient and autonomous smart home ecosystems.
