A survey of Blockchain integration with IoT: benefits, challenges and future directions

Abstract

The Internet of Things (IoT) stands at the forefront of the latest generation of information technology advancements, signifying a crucial juncture in the integration of digital and physical domains. This integration is pivotal, facilitating a plethora of transformative digital services that substantially enhance user experiences by seamlessly melding virtual and physical elements. However, the rapid proliferation of IoT also brings to the fore a range of challenges, particularly in the realms of security, simplicity, and data integration. These challenges pose significant obstacles to the full realization of IoT’s potential. This paper provides a comprehensive analysis of these challenges within the IoT framework. We delve into the intricacies of IoT environments, examining the security risks and integration complexities that arise. The paper proposes effective strategies to address these challenges, aiming to establish a more secure and reliable IoT infrastructure. We discuss innovative approaches for enhancing data integration and simplifying IoT systems while ensuring robust security measures are in place. Through this exploration, the paper aims to contribute to the ongoing development of IoT, offering insights into overcoming its current limitations and outlining a path for its future evolution. Our analysis underscores the need for continuous research and innovation in this field, setting the stage for the emergence of more advanced, secure, and user-friendly IoT applications across various industries.
