自從 2008金融風暴將銀行高信貸的危機及雷曼兄弟的倒閉打擊了投資人的信心，此時比特幣區塊鏈的去中心化技術開始受到矚目，研究人員與產官學術機構紛紛投入區塊鏈發 展，以區塊鏈為去中心的帳本技術與智能合約的結合，運用公私鑰加解密保障成員間的交易安全，共識機制的運用對於維護區塊鏈平台安全及完整性非常重要，工作量證明及權益證明保障多數成員於平台上共同利益擁有加密貨幣資產。除了公有鏈之外，私有鏈的特性難達成去中心化的需求，主要是私有鏈成員絕大部分為核心成員，共識決策通常代表高層所傳達的決定，另一種介於公有鏈網路結構又兼顧私有鏈隱密性質的商用區塊鏈，此類區塊鏈發展以 Linux基金會結合成員力量開發Hyperledger Project 旨在推動跨行業的應用；本論文以學習實作體驗公有鏈乙太坊測試環境來安裝執行 DApp 的開發步驟，實際了解編寫 Solidity 智能合約及執行合約耗用 gas 的過程，藉以比較學習使用商用私有鏈 Hyperledger Fabric 交易網絡架構的差異性，Hyperledger Fabric自學資源主要以官網釋出版本所附加安裝的範例做為參考。
本論文使用官網下載後安裝的範例，以自學的方式由手動漸進生成 Hyperledger Fabric的業務網絡，此網絡啟動之後能夠於節點 peer安裝 chaincode智能合約，經由客戶端程式註冊使用者與智能合約中業務邏輯達成互動；它是搭配各章節的內容循序漸進指引初學者如何來認識與啟動 Hyperledget Fabric專案。

Since the 2008 financial turmoil hit the confidence of investors due to the high credit crisis of banks and the collapse of Lehman Brothers. The decentralized technology of Bitcoin blockchain began to attract attention, and researchers and academic institutions of industry and government have invested in the block. The technology of blockchain-based decentralized ledger combine smart contracts, uses public and private key encryption and decryption to ensure the security of transac-tions between members. The use of consensus mechanisms is very important to maintain the security and integrity of the blockchain platform. The proof of workload and proof of rights both guarantee that most members have the common interests of cryptocurrency assets on the platform. In addition to the public chain, the characteristics of the private chain are difficult to achieve the demand for decentralization. The main reason is that most of the members of the private chain are core members. Consensus decision-making usually represents the idea conducted by the high-level. A commercial alliance blockchain that takes into account the hidden require of private chains. This type of block-chain development group uses the Linux Foundation to join the members strength to develop the Hyperledger Project, which aims to promote cross-industry applications; this paper uses self-study to experience the public blockchain Ethereum install and DApp execute steps in the test environment, and understand the process of writing Solidity smart contracts and executing contracts that con-sume gas fee, so as to compare the differences in the use of Hyperledger Fabric architecture. Hy-perledger Fabric self-study resources can be used from official download. After installation peoce-dure, example also attach for tutorial reference.
This paper uses the example from the official website to gradually generate the Hyperledger Fabric business network. After the network is started, the chaincode smart contract can be installed on the node peer, when the user registered through the client program that can interact with smart contract; it is a step-by-step guide with the content of each chapter to guide beginners how to un-derstand and start the Hyperledget Fabric project.
