區塊鏈(Blockchain)科技的快速發展已成為金融科技(FinTech)運用的新趨勢。由於區塊鏈的設計本於交易總帳(Transaction Ledger)技術的應用，架構於點對點網路(Peer-to-Peer Network)上的分散式資料記錄儲存結構，運用加密技術及共識演算法(Consensus Algorithm)，能夠抵抗資料不被竄改、迅速恢復系統運作之穩定性並保護資料備份。
本研究將探討區塊鏈技術在商業上可能的運用，引用國際上的實踐作可行性建議，運用文獻分析法深入瞭解並分析目前主流區塊鏈的白皮書與技術論文後，提出建置區塊鏈系統時，所須注意之關鍵因素，如何導入區塊鏈及其必要的核心元素，以輔助企業決策者能夠做出適合於企業創建，或是轉型之需求。
文中運用Hyperledger Fabric與Ethereum開放平台技術，對交易進行各項的驗證，並考慮不同之共識演算法以及智慧合約的組合，進行比較分析探討，最後並就研究中所遇到的問題進行整理。
Blockchain technology has been developed into one of the most important tech-nology innovation on the main stream of FinTech applications. With its original design focuses on building “A Peer-to-Peer electronic cash system” of future from Bitcoin, which makes the transaction ledger to be stored in a decentralized database on its peer-to-peer network system. It utilizes modern encryption and consensus algorithms to further protect system, data security and integrity from malicious intends.
In this research, we are going to provide a detailed step-by-step understanding on what the blockchain technology is, how to decide if your organization needs it or not, and most of all how to apply it onto your business model to be successful in the tomor-row market.
We will also compare Hyperledger Fabric and Ethereum system platforms in this research to show their pros and cons. At the end, reader should be able to tell which platform is the best choice for enterprise grade Blockchain system for their application as the technology evolving goes by now.
