Yes, a DAO can support transparent on-chain ticketing settlement in public transportation systems. By leveraging blockchain technology, a DAO can create a decentralized, tamper-proof ledger for ticket sales, usage, and revenue distribution. Smart contracts automate fare calculations, validate tickets, and ensure real-time settlement among stakeholders, such as transit authorities and service providers. All transactions are recorded on-chain, providing full transparency and auditability, reducing fraud, and enhancing trust. Passengers can purchase tickets via cryptocurrency or tokenized payments, with fares instantly verified and settled. The DAO's governance model allows stakeholders to vote on fare structures or system upgrades, ensuring fairness. This approach minimizes intermediaries, lowers costs, and improves efficiency. However, challenges like scalability, user adoption, and regulatory compliance must be addressed for practical implementation.
