Abstract

Since Satoshi Nakamoto first introduced the blockchain as an open-source project for secure financial transactions, it has attracted the scientific community’s interest, paving the way for addressing problems in domains other than cryptocurrencies, one of them being the Internet of Things (IoT). However, to demonstrate this potential, a clear understanding of blockchain technology and its suitability to meet the IoT’s underlying security requirements is required. To accomplish this goal, this study intends to provide a coherent and comprehensive survey on blockchain integration with IoT identifying the limitations and benefits of Blockchain in IoT applications. The survey presented an overview of blockchain and IoT and illustrated their principal architecture. The state-of-the-art blockchain efforts in different IoT domains are also reviewed. Then presents the current challenges of integrating blockchain and IoT and looks at the recently proposed solutions. Finally, the potential future research directions for integrating blockchain and IoT is discussed. Based on the study’s findings, it is hoped that this survey will serve as a reference and source of motivation for future research directions in this area.
