DriversBlock: A Blockchain-Based Driver License and Traffic Violation Data Management System for Sri Lanka

Abstract

DriversBlock is a decentralized application designed to modernize driver license issuance and traffic violation data management using blockchain technology. Traditional systems, which rely on paper-based processes or centralized databases, are prone to inefficiencies, data manipulation, and fraud. DriversBlock addresses these issues by leveraging a tamper‑proof ledger and employing soulbound tokens to ensure that driver licenses remain permanently bound to their rightful owners. The system incorporates role-based access control, enabling distinct functionalities for drivers, police officers, and licensing authorities, thereby enhancing transparency and trust. Integration with ThirdWeb for wallet management streamlines user authentication, making the platform accessible to both technical and non‑technical users. Although testing was conducted on a local Ganache environment due to challenges in obtaining Arbitrum test tokens, the architecture is fully EVM-compatible, allowing for a seamless transition to live deployment on Arbitrum in the future. Through a combination of qualitative and quantitative evaluations, DriversBlock has demonstrated its potential to significantly improve public recordkeeping and digital service delivery in the transportation domain. This project sets a new standard for secure, efficient, and scalable driver license and traffic violation data management.
