Abstract: Peer-to-peer (P2P) carpooling platforms have emerged as a promising solution to address transportation inefficiencies, reduce traffic congestion, and alleviate environmental impacts. However, existing P2P carpooling systems encounter challenges related to trust, security, and transparency. This work proposes a novel approach to enhance P2P carpooling through the integration of blockchain technology. Blockchain, a decentralized and immutable ledger, offers inherent advantages such as trust, transparency, and security. By leveraging blockchain, this proposed system aims to address key issues in P2P carpooling, including identity verification, payment settlement, and data integrity. Smart contracts, programmable self-executing agreements, enable automated transactions and enforce rules within the carpooling ecosystem.
