Key Features
Create powerful,end-to-end applications for Blockchain using Ethereum
Write your first program using the Solidity programming language
Change the way you think and design your applications by using the all new database-Blockchain
Book Description
Blockchain is a distributed database that maintains a continuously growing list of data records secured from tampering and revision. Every user is allowed to connect to the network,send new transactions to it,verify transactions,and create new blocks,making it permission-less.
This book will teach you what Blockchain is,how it maintains data integrity,and how to create real-world Blockchain projects using Ethereum. With interesting real-world projects,you will know about bitcoin,generating smart and secure contracts with Ethereum,building end-to-end applications for Blockchain.
You will learn concepts such as cryptography in cryptocurrencies,ether security,mining ,smart contracts,solidity,and more. You will also learn about web sockets,various API services for Ethereum,and much more.
The blockchain is the main technical innovation of bitcoin,where it serves as the public ledger for bitcoin transactions.
What you will learn
Walk through the basics of the Blockchain technology
Implement Blockchain’s technology and its features,and see what can be achieved using them
Build DApps using Solidity and Web3.js
Understand the geth command and cryptography
Create Ethereum wallets
Explore mining ecosystem

主要特征
使用Ethereum为Blockchain创建功能强大的端到端应用程序
使用Solidity编程语言编写您的第一个程序
通过使用全新的数据库Blockchain，改变您的想法和设计应用程序的方式
图书说明
Blockchain是一个分布式数据库，它保持不断增长的数据记录列表，从篡改和修订保护。允许每个用户连接到网络，向其发送新的事务，验证事务，并创建新的块，使其无权限。
这本书将会告诉你Blockchain是什么，它如何维护数据的完整性，以及如何用Ethereum创建真实世界的Blockchain项目。随着有趣的现实世界项目，您将了解比特币，与埃特雷西姆（Ethereum）建立智能和安全的合同，构建Blockchain的端到端应用程序。
您将学习诸如加密密码术，以太网安全性，采矿，智能合同，稳定性等方面的概念。您还将了解网络套接字，各种API服务，以及更多信息。
封锁是比特币的主要技术创新，作为比特币交易的公开分类账。
