Become a Blockchain Developer with Ethereum and Solidity
Become a Blockchain Developer with Ethereum and Solidity
Exploring the immersed part of the iceberg
About the Book
The blockchain is about so much more than crypto-currencies and financial applications. In fact, some argue that crypto-currencies are to blockchains what the email was to the Internet: an impressive proof-of-concept, but only a first one. The immersed part of the iceberg is this new generation of decentralized applications you can build on top of public blockchains like Ethereum in order to massively disrupt organizations, governance, energy, real estate, and so many more industries, all the way to democracy itself. This book explains everything you need to know about why the blockchain exists, how it works, and more importantly how you can leverage it to build your very own decentralized application. In that regard, it helps you create your first project from scratch, develop your first smart contract and the web application to interact with it, and even shows you how to deploy all of that to an actual blockchain network.
