The concept of smart cities has become prominent in modern metropolises due to the emergence of embedded and connected smart devices, systems, and technologies. They have enabled the connection of every "thing" to the Internet. Therefore, in the upcoming era of the Internet of Things, the Internet of Vehicles (IoV) will play a crucial role in newly developed smart cities. The IoV has the potential to solve various traffic and road safety problems effectively in order to prevent fatal crashes. However, a particular challenge in the IoV, especially in Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications, is to ensure fast, secure transmission and accurate recording of the data. In order to overcome these challenges, this work is adapting Blockchain technology for real time application (RTA) to solve Vehicle-to-Everything (V2X) communications problems. Therefore, the main novelty of this paper is to develop a Blockchain-based IoT system in order to establish secure communication and create an entirely decentralized cloud computing platform. Moreover, the authors qualitatively tested the performance and resilience of the proposed system against common security attacks. Computational tests showed that the proposed solution solved the main challenges of Vehicle-to-X (V2X) communications such as security, centralization, and lack of privacy. In addition, it guaranteed an easy data exchange between different actors of intelligent transportation systems.
由于嵌入式和互联智能设备、系统及技术的出现，智慧城市的概念在现代大都市中变得日益突出。它们实现了万物与互联网的连接。因此，在即将到来的物联网时代，车联网（IoV）将在新发展的智慧城市中发挥关键作用。车联网有潜力有效解决各种交通和道路安全问题，以防止致命撞车事故。然而，车联网面临的一个特殊挑战，尤其是在车对车（V2V）和车对基础设施（V2I）通信中，是确保数据的快速、安全传输以及准确记录。为了克服这些挑战，这项工作正在将区块链技术应用于实时应用（RTA），以解决车对万物（V2X）通信问题。因此，本文的主要创新点在于开发一个基于区块链的物联网系统，以建立安全通信并创建一个完全去中心化的云计算平台。此外，作者针对常见安全攻击对所提出系统的性能和弹性进行了定性测试。计算测试表明，所提出的解决方案解决了车对X（V2X）通信的主要挑战，如安全性、中心化和隐私缺失等问题。此外，它保证了智能交通系统不同参与者之间的数据轻松交换。
