區塊鏈技術藉著比特幣而發揚光大，經過將近十年的考驗，區塊鏈被視為足 以改變全球經濟模式的火紅科技，各種應用的想法如雨後春筍般出現，本文趁勢 提出台灣股票結算交割的區塊鏈應用。本文從最原始的區塊鏈系統——比特幣介 紹起，深入討論區塊鏈運作的機制，包括共識的形成與交易的驗證方式。比特幣 的區塊鏈系統中的某些設定對於股票結算交割來說是缺陷，本文提出改良的方式， 包括許可制的區塊鏈、引入特殊功能節點及採用實名制等，試圖讓區塊鏈技術能 夠完美的應用於結算交割系統。最後分析應用區塊鏈之後所能夠達到的經濟與社 會效益。 / After nearly ten-year challenge, blockchain was known because of Bitcoin, and regarded as the most famous technology that could change the way how the whole world works. Lots of application ideas appear at this moment, this paper tries to follow the trend and discuss about the Taiwan stock clearing and settlement system. Begin with the original blockchain system, Bitcoin, reveal how actually blockchain works including the formation of consensus and the way of transactions verification. There are some defects when implementing the application by using Bitcoin system directly. This thesis proposes the way to improve the blockchain system which includes permission blockchain system, special functional nodes and implementation of real name blockchain system, and try to make modified blockchian system applicable to clearing and settlement system. Last but not least, this thesis analyzes the benefit of economy and society when the application is employed.

目前，因應不同需求與應用情境的各式電子發票系統已被建立。儘管電子發票系統、區塊鏈技術與其相關的文件及平台已經存在，許多研究學者及廠商仍希望推展此技術並應用於其它領域。 本研究的目的在以區塊鏈技術為基礎建構電子發票平台，希望提出一種區塊鏈技術的新應用情境。首先，透過資訊計量學的方法分析980篇電子發票及區塊鏈的相關文獻以了解電子發票及區塊鏈的發展；接著，探討比特幣(Bitcoin)與區塊鏈(Blockchain)間的重要觀念與技術；最後，利用區塊鏈技術中的一種以太坊(Ethereum)來建立電子發票平台。 本研究中六項建構電子發票系統的需求如資料完整性、可驗證性、可用性、可稽核性、不可否認性與可溯源性可被達成。此架構不僅適用於發行一般的消費性電子發票更適用於向企業提供短期資金借貸如發票融資的應用情境。未來，在不同的實作需求下，將可探討整合區塊鏈另一項技術開放鏈(Openchain)以建立混合公開與私有節點的應用。 / Different e-invoice systems are designed to meet different needs and application scenarios. Although these systems areuseful and readily available, researchers and businesses hope to be able to expand the coverage of e-invoice systems using Blockchain technologies. This study proposes an e-invoice system based on Blockchain technologies which shows anotherapplication scenario of Blockchain technology and e-invoice system. First, a review of about 980 publicationson e-invoicing and Blockchain was carried outwithinformetrics used for further analysis so as to better understandthe development of e-invoice and Blockchain technologies. Second, the concepts and mechanisms of Bitcoin and Blockchain technologies were reviewed. Finally, an e-invoice system based on Ethereumwas proposed. The proposed system meets the six needs of an e-invoice system: integrity, authenticity, availability, auditability, non-repudiation and traceability. It is not only suitable for issuing general invoices but also can play a role in further invoicing applications such as invoice financing as well as agri-food supply chain traceability. In the future, Openchain or hybrid Blockchain infrastructure that combines public and private nodes can be consideredfor use in this proposed e-invoice system.

在世界許多地方，近年來，由於經濟狀況不佳，公民對政府的不滿情況已經很明顯。各國政府一直在努力調整和糾正一些政策。然而，中央銀行影響市場的許多方式是公民可以控制其貨幣體系的創新概念的動力。本文將研究其中一項名為比特幣的創新。 2008年金融危機之後，出現了一個新的命題，排除了任何中央政府免受某種貨幣的干預。創建了一個項目，考慮到在處理付款時，不需要中間人來執行用戶之間的交易。在最開始，沒有人注意到沒有人知道，但在過去幾年裡，現在眾所周知的比特幣已經受到全世界的關注，這個話題引起了大的消息。 在本文中，描述了理解比特幣生態系統的基本概念，並對此數字貨幣體系進行了簡要介紹。本文的主要焦點是比特幣在拉丁美洲的使用和傳播，並進行了深入的分析，發現與採用比特幣相關的經濟體的核心問題。本文強調兩個特定國家，委內瑞拉和阿根廷，主要是因為經濟原因。 / In many places around the world, the discontent from citizens towards governments because of poor economic situations has been evident in recent years. Governments have been trying to make adjustments and correct some policies. However, the many ways in which central banks influence markets has been the motivation for innovative concepts in which citizens can take control of their monetary system. This paper will study one of these innovations called Bitcoin. After the financial crisis of 2008, a new proposition arose to exclude any central government from the intervention of a given currency. A project was created bearing in mind that no intermediary would be needed to executed transactions between users when dealing with payments. At the very beginning no one paid attention and nobody know about it, but in the last few years, what is now well known as Bitcoin has received worldwide attention and big news has been arising from this topic. In this paper, the basic concepts for understanding the Bitcoin ecosystem is described, and a brief introduction regarding this digital currency system is undertaken. The primary focus of the paper is the usage and spread of Bitcoin in Latin America, and an in-depth analysis is done, finding core issues on economies which are related to the adoption of Bitcoin. The paper places an emphasis on two particular countries, Venezuela and Argentina, primarily because of economic reasons.
