The aim of this study is to provide a comprehensive review of the blockchain technology and its application in vehicular ad hoc networks (VANETs). This study not only provides a comprehensive overview of the blockchain technology and its application in VANETs, but also presents a historical account of the evolution of VANETs, from their inception to recent advancements, thereby providing a contextual framework for understanding the current state-of-the-art in this domain. This paper addresses the usage of different consensus mechanisms in the context of VANETs. It also makes comparisons between them based on the advantages that they offer, along with their downsides. The paper also explores the integration of blockchain applications in the Internet of Vehicles (IoV) and identifies open issues for future research. This study aims to summarize the advances in Vehicular Communication Systems using the decentralized communication model of blockchain.
