Genre: Business & Economics

This book teaches you how to use Solidity and the Ethereum project – second only to Bitcoin in market capitalization. Blockchain protocols are taking the world by storm, and the Ethereum project, with its Turing-complete scripting language Solidity, has rapidly become a front-runner. Technologists from all fields and skill levels are converging to learn blockchain development and the potential of powerful censor-proof "dapps" is drawing new non-programmers to the space. Unlike Bitcoin, Ethereum has its own scripting language called Solidity, and Solidity gets its syntax from JavaScript. Introducing Ethereum and Solidity presents the blockchain phenomenon in context; then it situates Ethereum in a world pioneered by Bitcoin. It explains why developers and non-developers alike should consider developing their skills in smart contract patterns and distributed application development. Finally, it reviews the fundamentals of JavaScript programming alongside its introduction to Solidity programming, so that people who are unfamiliar with JavaScript, or people with rusty skills, can follow along and get coding.Finally, you will deploy a dapp with a regular HTML interface that can be accessed on the Web. Every Solidity tutorial out there today has the same flaw: they are written for advanced JavaScript developers who want to transfer their skills to a blockchain environment that will feel familiar. This book is accessible to non-JavaScript developers as much as it is to JavaScript developers. It is a powerful gateway for creative technologists of all types, from concept to deployment./div What You’ll Learn How Ethereum (and other cryptocurrencies) work How distributed apps (dapps) are different than web apps How to write Ethereum smart contracts in Solidity language How to connect Ethereum smart contracts to your HTML/CSS/JavaScript web applications How to deploy your own dapp, coin, and blockchain How to work with basic and intermediate smart contracts Who This Book Is For Anyone who is curious about Ethereum will derive huge benefit from this book. It’s accessible to anyone who has some familiarity with computer science, including product managers, CTOs, computer science, self-taught hackers, and anyone else who wants to get up and running with Ethereum quickly -- but lacks a strong JavaScript or web app development background. Experienced JavaScript programmers can also skip the first few sections and get a powerful introduction to smart contract authorship, dapp development, and dapp deployment. By the end of this book they will have a deep understanding of how blockchains work, and will be able to deploy real censor-proof dapps in the wild. Experts will find the advanced sample projects in this book rewarding, too, simply because of the power of Solidity. This book contains exciting sample code that can move real world assets, which will appeal to academic and corporate programmers.

Blockchain For the Non-Technical*** THIS IS A PREVIEW PRINT ***I am IBM ́s official liaison to the Ethereum core developers and frequently give talks on blockchain topics around the world. After one keynote I was asked for a non-technical guide to understand blockchains. This is it.This book aims to help you get your head around blockchains in general and around Ethereum specifically.Since Ethereum is currently the pre-imminent blockchain, it makes sense as reference point. The essential stuff is the same for any blockchain.This text was written for people with a fast grasp, who are not programmers. Reading this should give you the basics to cut through the hype and to identify blockchain opportunities in your professional domain.There are tiny bits of code, which can be admired and skipped.We ́ll look at Ethereum ́s benefits first, how it is used and what can be done with it; then explain blockchain machinery, visiting the terms that you ́ll be confronted with in every discussion about its application. Exactly what you need to tell the noise from the signal in the echo chamber of honest misunderstandings and desperate marketing.We take a good hard look at limitations, throw in some history and names and give a realistic outlook.The index reads like an FAQ and you can use the book like that. However, there is a strong build up, one chapter leading to the next, as optimized path to understanding all the interconnected, moving parts. There ́s quite a number of them.Blockchains are not a trivial topic.The fact that blockchain client programs are small has fooled many people into believing it can ́t possibly be that hard. The challenges are in the implications though.But what's in this book will put you ahead of almost everyone outside the core bubble.If you find something explained badly, please yell at me at: ethereum.bookØgmail.comA deep dive into this field now - at least getting started - will help you to become part of the fun ahead. It should allow you to stand out, land deals or a great job.It will also make you see first hand how early we are in the game. Take your time! It ́s worth it.Hopefully, we will find a contributor to the blockchain community in you, strengthening the portfolio of real-world use cases. Ideally, you ́ll learn to navigate your own uncharted course through your domain and revolutionize it, applying blockchain tech where it really makes sense.From the Book's Index:What is Ethereum?What is Ether?What is Ethereum Not?What is Ethereum Used for?Create Your Own Digital Currency!How Does Ethereum Compare?How Does Ethereum Work?What is a Blockchain?What ́s the Magic?What is Holding It Back?What is a Cryptocurrency?What is a Digital Currency?What is a Digital Asset?What is a Mirror Asset?What is Mining?
