Overview of this book

Blockchain applications provide a single-shared ledger to eliminate trust issues involving multiple stakeholders. It is the main technical innovation of Bitcoin, where it serves as the public ledger for Bitcoin transactions. Blockchain Developer's Guide takes you through the electrifying world of blockchain technology. It begins with the basic design of a blockchain and elaborates concepts, such as Initial Coin Offerings (ICOs), tokens, smart contracts, and other related terminologies. You will then explore the components of Ethereum, such as Ether tokens, transactions, and smart contracts that you need to build simple DApps. Blockchain Developer's Guide also explains why you must specifically use Solidity for Ethereum-based projects and lets you explore different blockchains with easy-to-follow examples. You will learn a wide range of concepts - beginning with cryptography in cryptocurrencies and including ether security, mining, and smart contracts. You will learn how to use web sockets and various API services for Ethereum. By the end of this Learning Path, you will be able to build efficient decentralized applications. This Learning Path includes content from the following Packt products: • Blockchain Quick Reference by Brenn Hill, Samanyu Chopra, Paul Valencourt • Building Blockchain Projects by Narayan Prusty

Chapter 29. Building Enterprise Level Smart Contracts

Until now, we were using browser Solidity to write and compile Solidity code. And we were testing our contracts using web3.js. We could have also used the Solidity online IDE to test them. This seemed alright as we were only compiling a single small contract and it had very few imports. As you start building large and complicated smart contracts, you will start facing problems with compiling and testing using the current procedure. In this chapter, we will learn about truffle, which makes it easy to build enterprise-level DApps, by building an altcoin. All the crypto currencies other than bitcoin are called altcoins.

In this chapter, we'll cover the following topics:

  • What the ethereumjs-testrpc node is and how to use it?
  • What are topics of events?
  • Working with contracts using the truffle-contract package.
  • Installing truffle and exploring the truffle command-line tool and configuration file
  • Compiling, deploying, and testing Solidity code using...
