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

Creating one's own cryptocurrency

Once the previously listed parameters are defined, it is time to work on the source code and make the required changes, as needed.

Setting up Litecoin

It is important to set up the Litecoin environment in our local machine; the source code is available on GitHub here:

Platform selection

It is important to select the build platform on which the environment is to be set up. You can find the required build instruction in the doc subfolder of the source code. There, required instruction files for the preferred platforms are present for you to follow the steps to install the Litecoin core and the Wallet.

In this section, we will be working on Max OS X build instructions, although instructions for other platforms are also available in the suggested instruction path.


Installation of xcode is necessary for compilation of required dependencies. The following command should be executed in the terminal:
