Abstract

Blockchain technology has been making waves in recent years, and people are starting to think about how it could help to make Internet of Things (IoT) systems more secure and reliable. In this paper, we dive into how these two worlds could collide, looking at what the IoT is made up of (sensors, networks, devices, etc.) and how it could hook up with Blockchain. In theory IoT systems can address common challenges such as breaches of data, hacks, unauthorized access, and system failures by using Blockchain’s decentralized, tamper proof features. In addition, the paper looks at how smart contracts can automate operations in IoT systems to ensure secure, efficient communication between devices. We also elaborate on how Lightweight Blockchain frameworks and Energy efficient protocols can make Blockchain suitable for resource constrained IoT devices, opening the frontier in healthcare, supply chain and smart cities. However, despite the potential, we discuss the issues with such integration scalability, energy consumption and privacy concerns and leave directions for research on future seamless IoT-Blockchain integration.
