Blockchain Developer's Guide

By: Brenn Hill, Samanyu Chopra, Paul Valencourt, Narayan Prusty

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

Basics of Solidity

Solidity is not the only language to work on Ethereum smart contracts; prior to solidity, there were other languages that were not as successful. Here is a brief list of languages currently (as of August 2018) compatible with Ethereum:

  • Mutan: Inspired from Golang and deprecated in March 2015.
  • LLL: Short for lisp-like language. While it is still supported, it is rarely used.
  • Serpent: While this language is similar to Python, it is no longer recommended for use.
  • Solidity: The fourth language introduced by the Ethereum foundation, and so far the most successful language for developing smart contracts. It is the most documented, stable, and has a large community support.
  • Vyper: Newly introduced, much simpler and easier than Solidity, although it does not have much community support yet. It is influenced by Python.

Solidity is also known as a contract-oriented language, since contracts are similar to classes in object-oriented languages. The Solidity language is loosely based on...
