Iot e blockchain aplicados à automação residencial: desenvolvimento de um sistema seguro com controle em tempo real

Abstract

This study aims to develop a Home Automation system based on the integration between the Internet of Things (IoT) and Blockchain technology, seeking to promote a safer, smarter, and more efficient domestic environment. The adopted methodology involved the design and implementation of a functional prototype, in which connected devices such as sensors, actuators, and controllers were employed to perform automated tasks in real time. Blockchain technology was incorporated into the system to immutably record the transactions and interactions among devices, ensuring transparency and data protection. The results demonstrated that the combined use of these technologies significantly improves communication security, reduces vulnerabilities, and optimizes energy consumption, making the system more sustainable and scalable. Furthermore, the network performance remained stable even as the number of connected devices increased. The main contribution of this research lies in demonstrating that the application of Blockchain in Home Automation systems can establish new standards of security and reliability for smart environments, strengthening user privacy and operational efficiency. This study provides a promising technological foundation for the advancement of intelligent residential solutions aimed at data protection and secure automation.
