Abstract	A groundbreaking blockchain-based trust management approach is revolutionizing location privacy in Vehicular Ad Hoc Networks (VANETs), a vital part of Intelligent Transportation Systems (ITS). This solution tackles the persistent security issues in VANETs, particularly for Location-Based Services (LBS). Now, vehicles can request LBS while their personal data remains secure through a verified process and the establishment of anonymous zones. An advanced trust management algorithm also governs vehicle behavior. The integration of blockchain technology significantly strengthens data security, leading to a highly robust and impenetrable system. Rigorous testing confirms the system's ability to withstand various trust-based attacks, highlighting its effectiveness in safeguarding vehicle privacy and its practical application in real-world VANET environments. This innovation points to a promising future for secure and private ITS.
