The Internet of Things (IoT) has recently taken on a crucial role in numerous areas of our life, offering convenience and efficiency. One notable area of its application is in the growing adoption of smart home applications. This rapid growth has emphasized the pressing need to enhance the IT infrastructure to ensure the transparency, security, and privacy of user data. In this regard, blockchain technology has emerged as a promising solution to fulfill these critical demands. Hence, this study suggests an approach utilizing Hyperledger Fabric to enhance the security of smart home systems through blockchain technology. The proposed solution addresses the security limitations often encountered in existing permissioned blockchain approaches. The architecture consists of four layers: Cloud Storage Layer, Blockchain Platform Layer, Application layer and IoT Devices Layer. We have integrated a cloud storage layer to take benefit of its inherent advantages in terms of efficiency and availability. Smart home devices frequently require computing resources and substantial storage capacity, both of which can be effectively provided by the cloud.
