    • 自2016年以來比特幣的價格大幅上漲，加密貨幣及其
    底層技術區塊鏈已成為頭條新聞。區塊鏈一直蓬勃發展過去十年。它在確保不變性方面具有特別的優勢保證交易的透明度。它的分散性和自動化計算功能帶來了教育部門增值的潛力。在裡面在研究之後，我們提出了一個發布以太坊學術證書的平台區塊鏈。我們還討論了區塊鏈在全球教育中的應用以及如何實施以支持台灣的教育體系。世界各地的各種知名教育機構已經開始通過基於區塊鏈的平台發放學歷證書。我們也評估現有的各種教育機構頒發學歷證書的製度在台灣，並建議基於區塊鏈的應用程序如何有助於加強那個系統。

    With a significant rise in the price of Bitcoin since 2016, cryptocurrency and its underlying technology blockchain has created headlines. Blockchain has been flourishing for the past decade. It has particular advantages in securing immutability and guaranteeing transparency in transactions. Its decentralized nature and automatic
    computing feature bring the potential of adding value in the education sector. In the following study, we propose a platform to issue academic credentials on ethereum blockchain. We also discuss the applications of blockchain in education worldwide and the ways in which it can be implemented to support Taiwan’s education system. Various renowned education institutions around the world have already started to issue academic credentials through blockchain based platforms. We also evaluate the existing system for issuing academic credentials in various education institutes in Taiwan and suggest how blockchain based application can assist in strengthening that system.
