    Abstract: 當前的全球趨勢顯示,央行數位貨幣 (CBDC) 對未來銀行業和金融業至關重要。根據 CBDC Tracker 的數據,截至 2021 年 12 月,至少有 64 家中央銀行正在探索央行數位貨幣,其中20 家已經啟動或測試了央行數位貨幣,如中國、英格蘭、瑞典等金融體系成熟國家,而到2022年已達到144個國家。
    目前對央行數位貨幣的研究主要都集中在傳統金融技術和區塊鏈技術上,並且以區塊鏈為大宗,但尚不清楚這種技術選擇是否提供了最佳解決方案。
    在本論文中,我們結合區塊鏈和傳統電子金融系統的優勢,設計出一款適合央行數位貨幣的支付系統模型,系統中提供合適的隱私性,高擴展性,並有利於監管,這些都是CBDC關鍵的要素。
    The current global trends show that central bank digital currencies (CBDCs) are crucial to both financial industry and banking in the future. According to the CBDC Tracker, as of December 2021, at least 64 central banks are exploring central bank digital currencies. 20 of them have launched or tested central bank digital currencies such as China, England, and Sweden who have mature financial systems. As at 2022, it has reached 144 countries.
    Most of the current researches about the central bank digital currencies focus on the traditional financial technology and blockchain technology, with blockchain as the bulk. However, it is still unclear that these two choices would be the best solution.
    In this thesis, we combine the advantages of blockchain and traditional electronic financial systems to design a payment system model suitable for CBDC. The system provides privacy, high scalability, and facilitates supervision which are key elements of a CBDC.
