Vehicle inspection is required in Mauritius to ensure roadworthiness and passenger safety. During visits to vehicle fitness centres, various inspection flaws were identified, indicating potential collusion between staff and vehicle owners. Certain tests were omitted or not recorded in the centralised database, potentially favouring vehicle owners. Furthermore, manual entry of test results into the software introduced human errors and compromised data integrity, posing risks to the information’s confidentiality, integrity, and availability. To address these issues and combat corruption, this project proposes a smart blockchain-based vehicle fitness recording decentralised application (DApp). Through in-depth analysis, a technologically secure blockchain platform was selected for storing fitness data while leveraging the Firebase Cloud backend-as-a-service infrastructure to enhance security and mitigate threats such as Man-in-the-Middle attacks. The DApp consists of two secure web applications: an examiner portal for conducting vehicle inspections and a supervisor portal for monitoring vehicle counts and reviewing blockchain transactions. The DApp successfully stored recorded values on the Ethereum Goerli Test Network using the Proof of Stake (PoS) consensus algorithm. Evaluation by programming experts yielded an overall QXScore of 85%, indicating positive user interface and user experience functionalities.
