A Blockchain-based Transaction Verification Infrastructure in Public Transportation

Abstract

This paper proposes a new blockchain-based transaction verification infrastructure for co-payment and data verification for multi-modal public transportation systems.Our solution offers a decentralized platform that ensures secure copayments and data integrity while addressing interoperability, data security and transactional transparency.With a private blockchain, transportation providers act as nodes and validated, consensus-approved transactions increase trust and transparency.A standardized data format and robust algorithms for data contribution by transport operators are developed as well as a model for operators, assets, and transactions.Including zero-knowledge proofs improves user privacy by allowing secure authentication without revealing sensitive data.We believe that this research may lead a closer collaboration between public transport operators and provide an enhanced user experience while enabling transport transaction security and data verification.
