| Summary: | Technological advancement brings both opportunities and challenges to several sectors, including transportation. In Malaysia, the car grant system managed by the Road Transport Department (JPJ) is crucial for accurate vehicle registration and ownership but is vulnerable to fraud, like car grant forgery and unauthorized transfers. This study suggests using the Ethereum blockchain to enhance the integrity of the car grant system within the JPJ to curb these fraudulent activities. Ethereum's decentralized and distributed ledger technology, which offers transparency, immutability, and security, is perfect for this purpose. The suggested system uses smart contracts, self-executing agreements with preset rules, to ensure secure car grant registration and transfers. These contracts execute operations securely, preventing unauthorized changes. A prototype was developed and tested to evaluate the feasibility and efficacy of the system, including transaction speed, security, scalability, and user experience. The results gave valuable insights into the system's strengths and weaknesses, allowing for further optimization. This secure and transparent method could revolutionize vehicle registration and ownership procedures, enhancing trust, efficiency, and accountability in the Malaysian transportation sector. © 2023 IEEE.
