區塊鏈是一種點對點網路形式的分散式資料庫，可實現去中心化(decentralized)、資料無法被片面竄改(indelible ledger)以及透明公開的交易(Transparent)等特性。去中心化不僅能取代第三方的昂貴費用以及風險，如惡性倒閉與捲款潛逃，而資料無法被片面竄改與透明公開性來確保交易的真實與公平性。目前區塊鏈已經從數位貨幣漸漸發展到智能合約與分散式帳本的相關應用，更是是Fintech與物聯網(IoT)等產業不可或缺的應用趨勢，本課程將介紹如何利用Ethurum及 Hyperledger等區塊鏈相關技術，考慮區塊鏈底層及應用面的安全問題，來實作更多創新應用。

Blockchain is a decentralized database in the form of a peer-to-peer network, which can achieve characteristics such as decentralization, data that cannot be tampered with (indelible ledger), and transparent and open transactions (Transparent). Decentralization can not only replace the expensive costs and risks of third parties, such as vicious bankruptcies and absconding with money, but the data cannot be unilaterally tampered with and transparency and openness ensure the authenticity and fairness of transactions. At present, blockchain has gradually developed from digital currency to related applications of smart contracts and distributed ledgers, and is an indispensable application trend in industries such as Fintech and the Internet of Things (IoT). This course will introduce how to use blockchain-related technologies such as Ethurum and Hyperledger, and consider the security issues of the underlying and application aspects of the blockchain to implement more innovative applications.
