A Beginner S Journey To Ethereum S Smart Contracts

The potentials of Ethereum smart contracts--powered by the ubiquitous Blockchain technology--has been the subject of raging debate in recent times. Pundits have long held the argument that smart contracts hold the promise of curing hurdles associated with financial contracts, banking transactions, e-commerce, logistics, supply chain and legal contracts. It is no secret that reliance on classical contracts--which uses physical documents--has led to delays in transactions, inefficiencies, and exposures to fraudulent activities. Employing smart contracts can help companies lower administration costs, reduce risks, and promote efficient business operations across multiple sectors of the economy. However, to appreciate these benefits and develop better smart contracts, developers have understood how to use the technologies to engineer Blockchain projects. This book provides a big picture view of engineering Ethereum smart contracts. It delves deeper to explore how Solidity and Web3.Js can be used to build enterprise-level smart contracts and DApps. The book has been structured into 10 chapters as follows:* Chapter 1: Overview of Blockchain and smart contracts. It explores the basic concepts about Blockchain, cryptography, smart contracts, and DApps to provide you with a solid understanding on what is required to start creating smart contracts.* Chapter 2: Smart Contracts with Web3.Js. It introduces you to Web3.Js and how you can use it to start building smart contracts. * Chapter 3: Smart Contracts Events with Web3.Js. You will learn all the basics of applying smart contract events in Web3.Js.* Chapter 4: Functions, mappings, and structs. It explores the Solidity's functions, mappings and structs and how to use them to enhance the development of smart contracts. * Chapter 5: Inheritance and Deployment. It examines how smart contracts can be inherited and deployed on the Ethereum Virtual Machine (EVM).* Chapter 6: Embark Framework. It examines the Embark framework and how it can fast-track the development and deployment of smart contracts on EVM.* Chapter 7: Testing Smart Contracts. It explores how smart contracts can be tested in different environments.* Chapter 8: Contracts Management with Factories. It examines how factories can be used to manage multiple smart contracts.* Chapter 9: IPFS and Web Hosting. It introduces the Interplanetary File System protocol and how it can be leveraged to host smart contracts.* Chapter 10: End-to-end Development of DApps. It summarizes the various steps involved in the development of DApps. Ultimately, the focus of this book is an exploration of all aspects of smart contracts and DApps that you need to know for you to start creating Ethereum-based Blockchain projects. Let's get started.

Learn 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. This book presents the blockchain phenomenon in context; then situates Ethereum in a world pioneered by Bitcoin. See why professionals and non-professionals alike are honing their skills in smart contract patterns and distributed application development. You'll review the fundamentals of programming and networking, alongside its introduction to the new discipline of crypto-economics. You'll then deploy smart contracts of your own, and learn how they can serve as a back-end for JavaScript and HTML applications on the Web. Many Solidity tutorials out there today have the same flaw: they are written for “advanced” JavaScript developers who want to transfer their skills to a blockchain environment. Introducing Ethereum and Solidity is accessible to technology professionals and enthusiasts of all levels. You’ll find exciting sample code that can move forward real world assets in both the academic and the corporate arenas. Find out now why this book is a powerful gateway for creative technologists of all types, from concept to deployment.

In this book, we take you on a fun, hands-on and pragmatic journey to learning decentralized application (DApp) development on the Ethereum blockchain using the Solidity programming language. You'll start building your first Ethereum smart contract within minutes. Every section is written in a bite-sized manner and straight to the point as I don't want to waste your time (and most certainly mine) on the content you don't need. In the end, you will have what it takes to develop a real-life decentralized eBay Clone app. In the first chapter, we see how Ethereum works and why do we care about it. In the second chapter, we will create our first working smart contract with Ethereum where we learn how to interact with Ethereum as developers. We will then move on to chapters three and four where we will learn about compiling, deployment and testing of Ethereum apps. All these will prepare us for development of our decentralized eBay clone smart contract and the React user front end in chapter five and six. The goal of this book is to teach you how to build decentralized apps with Ethereum. We won't be talking a lot about trading cryptocurrencies, how to invest in Ethereum or how to trade Ethereum (ether) coins. We will have a good overview of Ethereum and cryptocurrencies but we will not be going into super in-depth academic discussion of them as our focus in this book is to have the practical knowledge of how to work with and build products with Ethereum.
