EtherFineChain: A Blockchain-Based Framework for Secure Traffic Violation Logging and Cryptocurrency Penalty Enforcement Using Ethereum Smart Contracts

Abstract

New-generation traffic violation systems are often plagued by issues related to data tampering, transparency, and poor record-keeping. To overcome these limitations, this paper proposes EtherFineChain, a blockchain-based framework for traffic violation logging and cryptocurrency penalty enforcement utilizing smart contracts. The system records decentralized, tamper-proof and verifiable storage of key violations data like vehicle number, evidence references for legitimate stakeholders. A working prototype has built and deployed on the simulated environment - Ganache, enabling automated fine deduction and immutable record keeping. Experimental evaluation shows that the average transaction latency is 134.48 ms and transaction throughput is 7.43 transactions/sec(approx.), and handles over 500 records per hour under simulation. Although the current version is founded on pre-processed inputs, the architecture is designed to support real-time detection and automated pipelines in upcoming versions. EtherFineChain provides a scalable and independent foundation for digital traffic management, laying the groundwork for secure integration into smart-city infrastructures.
