Every year, the Industrial University of Ho Chi Minh City presents a cultural program in conjunction with the start of the academic year. Students from the school are given free tickets to attend this event. However, there has been an occurrence problem with fake tickets or ticket sales appearing throughout the years. To assure the validity of the ticket issued, we suggest a ticketing issuance and ticketing traceability management system by applying smart contract technology on the blockchain platform to store, manage, and trace the origin of tickets. The system is designed on the Ethereum platform to implement smart contracts and blockchain technologies using the Solidity language. A blockchain is a decentralized database that holds data in encrypted chunks that grow over time. These information blocks function independently. The benefit of block chain is that it offers great security by preventing information theft and manipulation. To evaluate the performance of the suggested system, it was carried out with real student data at the Faculty of Information Technology at the Industrial University of Ho Chi Minh City. The experimental results show that the proposed system carries out all functions well.
