Blockchain By Example

By: Bellaj Badr, Richard Horrocks, Xun (Brian) Wu

Overview of this book

The Blockchain is a revolution promising a new world without middlemen. Technically, it is an immutable and tamper-proof distributed ledger of all transactions across a peer-to-peer network. With this book, you will get to grips with the blockchain ecosystem to build real-world projects. This book will walk you through the process of building multiple blockchain projects with different complexity levels and hurdles. Each project will teach you just enough about the field's leading technologies, Bitcoin, Ethereum, Quorum, and Hyperledger in order to be productive from the outset. As you make your way through the chapters, you will cover the major challenges that are associated with blockchain ecosystems such as scalability, integration, and distributed file management. In the concluding chapters, you’ll learn to build blockchain projects for business, run your ICO, and even create your own cryptocurrency. Blockchain by Example also covers a range of projects such as Bitcoin payment systems, supply chains on Hyperledger, and developing a Tontine Bank Every is using Ethereum. By the end of this book, you will not only be able to tackle common issues in the blockchain ecosystem, but also design and build reliable and scalable distributed systems.

Summary

Tired? I really hope not, because this was just the beginning of a long adventure. Hopefully, throughout this chapter, you were able to develop an understanding of the fundamentals of DApps and smart contract development. We covered, in a simplified way, the basics of Solidity and web3.js and how to build and deploy a simple full DApp.

While we have created a working DApp, it's by no means the final word in smart contract security and structural optimization. You'll still need to define functions to transfer ownership and open a bid, and add over- and underflow protection measures, just to name a few. I'll be glad to receive your propositions on the project's repository (https://github.com/bellaj/Car_Auction).

In the next chapter, we will take the learning process a step further, covering new concepts in Ethereum and digging deeper into Solidity&apos...
