n the imminent future, with the immense need for improving road safety and demand for enhancing the overall driving experience, the utility of vehicular ad-hoc networks technology (VANET) becomes well pronounced. But, the major setbacks of VANET are centralized architecture and the lack of privacy-preserving mechanisms. As it is evident, blockchain technology is gaining attention because of the features like decentralization, distributive, cooperative maintenance and non-tampering nature. This paper presents a decentralized architecture of VANET comprising blockchain technology. The proposed blockchain-based model for VANET works in four stages: blockchain network initialization, vehicle registration, pseudonym upload, and blockchain maintenance. This can efficiently solve the problems emerging in centralized architectures and helps in resolving trust issues between the entities. We propose an algorithm for protecting location privacy and providing anonymity. Experimental analysis proves that the given architecture performs better than the existing solutions.

在迫在眉睫的未来中，由于对改善道路安全性的巨大需求以及对增强整体驾驶体验的需求，车载自组织网络技术（VANET）的实用性变得十分突出。但是，VANET的主要挫折是集中式体系结构和缺乏隐私保护机制。显而易见的是，由于去中心化，分布式，合作维护和不篡改的特性，区块链技术正在受到关注。本文提出了一种包含区块链技术的VANET分散式架构。拟议的基于VANET的基于区块链的模型分四个阶段工作：区块链网络初始化，车辆注册，化名上传和区块链维护。这可以有效解决集中式体系结构中出现的问题，并有助于解决实体之间的信任问题。我们提出了一种用于保护位置隐私并提供匿名性的算法。实验分析证明，给定的体系结构比现有解决方案具有更好的性能。
