Abstract:	隨著區塊鏈技術的快速發展，其在售票系統領域的應用潛力日益受到關注。然而，現有的基於區塊鏈的票務系統仍面臨著諸多挑戰，如機器人搶票、黃牛炒賣票券、二級市場不成熟、用戶體驗不佳等。為了應對這些挑戰，本論文提出了一種創新的基於區塊鏈智能合約的票務管理系統解決方案。本論文首先深入分析了區塊鏈技術和智能合約的特性，以及它們在票務系統中的應用優勢。在此基礎上，設計了一套完整的智能合約體系，包括具有特殊限制之 NFT 票券、多種銷售模式和 NFT 二級市場智能合約，實現了安全、透明、公平、高效的票務功能。同時，本論文還創新性地利用 ChainLink VRF 實現了鏈上隨機數的生成，以保證隨機抽籤銷售的公平性;採用 IPFS 實現了鏈下數據的去中心化存儲;並利用 TheGraph 實現了鏈上事件的高效監聽和查詢。本論文成果對推動區塊鏈技術在票務領域的應用具重要意義，為解決當前票務系統面臨的諸多問題提供新的思路和方法。未來，還可以進一步探索智能合約在更複雜場景下的設計優化、與去中心化身份( Decentralized Identity,DID ) 系統的結合，以提高系統的適用性和擴展性，並拓展至更多的應用場景，如體育賽事、演唱會、展覽等領域。;With the rapid development of blockchain technology, its potential for application in the ticketing system domain has attracted increasing attention. However, existing blockchain-based ticketing systems still face numerous challenges, such as ticket snatching by bots, ticket scalping, immature secondary markets, and poor user experience. To address these challenges, this research proposes an innovative ticket management system solution based on blockchain smart contracts. Firstly, this research thoroughly analyzes the characteristics of blockchain technology and smart contracts, as well as their advantages in ticketing systems. On this basis, a comprehensive smart contract system is designed, including NFT tickets with special restrictions, various sales models, and NFT secondary market smart contracts, realizing secure, transparent, fair, and efficient ticketing functions. Moreover, this research utilizes ChainLink VRF to generate on-chain random numbers, ensuring the fairness of random draw sales; employs IPFS for decentralized off-chain data storage; and leverages TheGraph for efficient on-chain event monitoring and querying. The results of this research have significant implications for promoting the application of blockchain technology in the ticketing field, providing new ideas and methods to solve the many problems faced by current ticketing systems. In the future, further exploration can be conducted on optimizing smart contract design in more complex scenarios, integrating with decentralized identity systems to enhance the system′s applicability and scalability, and expanding to more application scenarios, such as sports events, concerts, exhibitions, and other domains.
