Published by Packt Publishing

Advanced content levelAdvanced

Setup Ethereum Blockchains and learn how to create your own smart contracts

Blockchain technology has indicated potential to completely shift to an era of programmable assets, enabling trust online, ownership of digital data, money, identity, and contracts. Today, every industry is building capabilities and experimenting to leverage Blockchain to improve their businesses. This online course begins with setting the context for why Blockchain has become mainstream in such a short span of time. It further explores Blockchain key constructs, such as distributed network, consensus protocol, and encryption. Discover how Blockchain actually works, through an example of bitcoin Blockchain and a practical demonstration to understand how transactions are stored on Blockchain. You’ll also learn about various Blockchain use-cases in industries worldwide, to develop understanding on how could this technology help in your area. You’ll also gain an understanding of the Ethereum platform and core concepts such as Gas, EVM, etc. We’ll explore Remix IDE and Truffle framework to create, deploy, and test smart contracts. In addition, learn how to setup your own private Ethereum Blockchain using Ganache. Furthermore, you will learn how different innovative solutions are built using cryptocurrencies, and how Blockchain is powering new ways of fundraising through initial coin offering (ICO). We’ll also review different token issuance specifications such as ERC20, ERC223 and ERC721. You’ll become familiar with emerging market trends and regulatory stand from different countries.

What you’ll learn and how you can apply it

  • Insights about Blockchain and key concepts like distributed network, consensus, and encryption
  • Understand how Blockchain works, through a demo
  • Discuss the compelling use-cases of Blockchain across different industries
