本研究設計、實現一個基於區塊鏈智能合約、多重簽章的活動票券建立販賣系統，並加以評估使用成本與可用性。基於區塊鏈與智能合約，使交易資料不易遭到竄改，且公平。實驗結果顯示，本研究所提出的系統有可接受成本，且應有機會使用於日常之中。

We develop a blockchain-based mobile ticketing system which utilizes smart contracts and multi-signature to enforce and authorize the executions of transactions. The transactions of buying and using mobile tickets are verified by the blockchain, and the immutable ledger and multi-signature on the blockchain ensures the authenticity and security of the tickets. The experimental results show that the proposed system is very efficient and requires only a nominal cost.
