Road accidents and traffic congestion severely impact road safety, resulting in significant loss of life property. Therefore, there is a need for safety management. The wireless networks connected vehicles called Vehicular Adhoc Networks (VANETs) are designed to improve the management on highways with comfort drivers passengers. However, develop an authentication scheme that can protect privacy secure them against attacks such as insider repudiation attacks. In this article, we present performs vehicle registration message forwarding VANETs appends transactions blockchain. proposed privacy-preserving using blockchain technology enables Trusted Authorities (TA) authenticate while preserving privacy. facilitates by deploying decentralized network. ensures privacy, confidentiality, integrity, transparency during VANETs. scheme, process automated use smart contract. We comparatively evaluate security performance state-of-the-art literature. significantly reliable transparent authenticating
