| Summary: | 碩士 === 銘傳大學 === 資訊管理學系碩士班 === 107 === With the rapid development of commercial and public welfare activities, the application of vouchers has become more diverse and the functions have become more and more complete. Many colleges and universities use paper vouchers instead of cash for students in financial need. However, traditional paper vouchers have drawbacks such as forgery, damage, loss, thievery, inconvenient carrying, poor application and review efficiency, and mistrust between organizations. Blockchain technology uses cryptography, consensus mechanisms, decentralized ledger and container technology to respond to various types of data storage, and has the characteristics of decentralization, immutability and undeniability, making it applicable to finance, logistics, medical care, education, etc. This study explores how to apply blockchain technology to solve the lack of paper meal voucher, and through consortium chain of blockchain technology, cryptography, QR Code and mobile devices to build a campus charity voucher system with security, trust and ease of use. The main contributions of this study include: (1) Let the consortium chain of blockchain technology import to the application field of campus charity voucher and establish a feasible practical application mode. (2) Complete the implementation of the campus charity voucher system with Hyperledger Fabric blockchain technology and Kafka sorting service. (3) It is proved by a large amount of experimental data that the system has good execution efficiency.
