### 知识点概述 本书《Packt.Hands-on.Blockchain.Development.with.Hyperledger》是一本关于区块链开发的实用指南,专注于使用Hyperledger技术创建私有区块链应用。以下是根据提供的信息总结的关键知识点: #### 区块链的概念与Hyperledger技术 区块链是一种分布式账本技术,它通过加密哈希函数和共识机制来验证和记录交易。其主要特点包括去中心化、不可篡改和透明性。Hyperledger是由Linux基金会支持的开源项目,旨在开发企业级的区块链技术,用于构建具有高透明度、安全性和可靠性的分布式账本应用。 #### Ethereum、R3 Corda、Coco与Hyperledger的对比 本书会首先介绍区块链的发展历程,并对比当前流行的区块链平台,包括Ethereum、R3 Corda、Coco等。这些平台各自有不同的设计哲学和技术路线,其中Hyperledger更专注于提供企业级的区块链解决方案。 #### Hyperledger Fabric的设置与启动 Hyperledger Fabric是Hyperledger项目中的一种企业级分布式账本框架,特别适合构建企业私有区块链。本书将指导如何在Bluemix(IBM提供的云服务平台)上设置和启动Hyperledger Fabric,为读者提供实践操作的机会。 #### Hyperledger Fabric的架构与组件 Hyperledger Fabric的架构设计允许创建灵活的网络拓扑结构,支持模块化和组件化。其中的关键组件包括Ordering服务、Peer节点、Membership Service Provider (MSP)等。理解这些组件的运作方式对于构建私有区块链应用至关重要。 #### 私有区块链网络的搭建与管理 本书会深入探讨如何与Hyperledger Fabric区块链进行交互,以从零开始搭建私有网络。这涉及许多核心概念,如链码(Chaincode)、智能合约(Smart Contracts)、加密货币等,都是构建Hyperledger网络所必需的。 #### 链码与智能合约的原理与应用 链码是运行在Hyperledger Fabric网络中的代码,它定义了网络的业务逻辑,并可以被用于创建智能合约。智能合约是自动执行合同条款的代码,它利用区块链的不可篡改性保证合同的执行不会被非法干预。 #### 加密货币与区块链生命周期的关键痛点 加密货币(如比特币、以太币等)在区块链中扮演重要角色。本书将会讨论加密货币与区块链生命周期管理中的关键痛点,比如交易的验证、网络共识、以及性能和可扩展性问题。 #### 自主部署去中心化应用(DApp) 最终,本书的目标是让读者能够使用Hyperledger构建和部署自己的去中心化应用。在解决企业应用中遇到的关键问题的同时,掌握区块链应用开发的关键技能。 ### 结语 本书《Packt.Hands-on.Blockchain.Development.with.Hyperledger》不仅是对Hyperledger技术的深入学习,也是对区块链开发全貌的全面认识。读者将通过实际操作Hyperledger Fabric来构建私有区块链应用,从而掌握将理论知识转化为实践能力的全过程。通过这本书,开发者和企业能够有效地利用区块链技术解决现实问题,进而推动整个行业的创新和发展。

Implement real-world decentralized applications using Python, Vyper, Populus, and Ethereum Key Features • Stay up-to-date with everything you need to know about the blockchain ecosystem • Implement smart contracts, wallets, and decentralized applications(DApps) using Python libraries • Get deeper insights into storing content in a distributed storage platform Book Description Blockchain is seen as the main technological solution that works as a public ledger for all cryptocurrency transactions. This book serves as a practical guide to developing a full-fledged decentralized application with Python to interact with the various building blocks of blockchain applications. Hands-On Blockchain for Python Developers starts by demonstrating how blockchain technology and cryptocurrency hashing works. You will understand the fundamentals and benefits of smart contracts such as censorship resistance and transaction accuracy. As you steadily progress, you'll go on to build smart contracts using Vyper, which has a similar syntax to Python. This experience will further help you unravel the other benefits of smart contracts, including reliable storage and backup, and efficiency. You'll also use web3.py to interact with smart contracts and leverage the power of both the web3.py and Populus framework to build decentralized applications that offer security and seamless integration with cryptocurrencies. As you explore later chapters, you'll learn how to create your own token on top of Ethereum and build a cryptocurrency wallet graphical user interface (GUI) that can handle Ethereum and Ethereum Request for Comments (ERC-20) tokens using the PySide2 library. This will enable users to seamlessly store, send, and receive digital money. Toward the end, you'll implement InterPlanetary File System (IPFS) technology in your decentralized application to provide a peer-to-peer filesystem that can store and expose media. By the end of this book, you'll be well-versed in blockchain programming and be able to build end-to-end decentralized applications on a range of domains using Python. What you will learn • Understand blockchain technology and what makes it an immutable database • Use the features of web3.py API to interact with the smart contract • Create your own cryptocurrency and token in Ethereum using Vyper • Use IPFS features to store content on the decentralized storage platform • Implement a Twitter-like decentralized application with a desktop frontend • Build decentralized applications in the shape of console, web, and desktop applications Who this book is for If you are a Python developer who wants to enter the world of blockchain, Hands-On Blockchain for Python Developers is for you. The book will be your go-to guide to becoming well-versed with the blockchain ecosystem and building your own decentralized applications using Python and library support.
