Learn Blockchain Programming with JavaScript

Book Description

Explore the essentials of blockchain technology with JavaScript to develop highly secure bitcoin-like applications

Key Features

• Develop bitcoin and blockchain-based cryptocurrencies using JavaScript
• Create secure and high-performant blockchain networks
• Build custom APIs and decentralized networks to host blockchain applications

Book Description

Learn Blockchain Programming with JavaScript begins by giving you a clear understanding of what blockchain technology is. You’ll then set up an environment to build your very own blockchain and you’ll add various functionalities to it. By adding functionalities to your blockchain such as the ability to mine new blocks, create transactions, and secure your blockchain through a proof-of-work you’ll gain an in-depth understanding of how blockchain technology functions.

As you make your way through the chapters, you’ll learn how to build an API server to interact with your blockchain and how to host your blockchain on a decentralized network. You’ll also build a consensus algorithm and use it to verify data and keep the entire blockchain network synchronized. In the concluding chapters, you’ll finish building your blockchain prototype and gain a thorough understanding of why blockchain technology is so secure and valuable.

By the end of this book, you’ll understand how decentralized blockchain networks function and why decentralization is such an important feature for securing a blockchain.

What you will learn

• Gain an in-depth understanding of blockchain and the environment setup
• Create your very own decentralized blockchain network from scratch
• Build and test the various endpoints necessary to create a decentralized network
• Learn about proof-of-work and the hashing algorithm used to secure data

书名：Learn Blockchain Programming with JavaScript

用JavaScript探索区块链技术要领，开发高度安全的比特币类应用

Key Features

• 使用JavaScript开发基于比特币和区块链的加密货币
• 创建安全、高性能的区块链网络
• Build custom APIs and decentralized networks to host blockchain applications

图书描述

学习使用JavaScript进行区块链编程首先让您清楚地了解什么是区块链技术。然后，您将设置一个环境来构建您自己的区块链，并且您将为其添加各种功能。通过向您的区块链添加功能，例如挖掘新区块、创建交易以及通过工作证明保护您的区块链，您将深入了解区块链技术的工作原理。

随着你读完这些章节，你将学习如何构建一个API服务器来与你的区块链交互，以及如何在一个分散的网络上托管你的区块链。您还将构建一个共识算法，并使用它来验证数据并保持整个区块链网络的同步。在最后几章中，你将完成你的区块链原型的构建，并彻底理解为什么区块链技术如此安全和有价值。

到本书结束时，您将了解去中心化区块链网络是如何运作的，以及为什么去中心化是保护区块链安全的一个如此重要的功能。

你将学到什么

• 深入了解区块链和环境设置
• 从头开始创建您自己的去中心化区块链网络
• 构建并测试创建分散网络所需的各种终端
• 了解工作证明和用于保护数据的哈希算法
• 挖掘新块、创建新事务并将事务存储在块中
• 探索共识算法并将其用于区块链网络同步

这本书是为谁而写的

学习区块链编程与JavaScript是面向希望了解区块链编程或使用JavaScript框架构建自己的区块链的JavaScript开发人员。
