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.
About the Authors
Software engineer by training and by passion, Sebastien has always been fascinated by the impact software can have on our lives, our thinking and our societies. He has always tried to find the most effective and expressive ways to write software so that he could focus on what it could achieve, rather than how it could do it. When he first came in contact with decentralization and blockchain, he was hooked right away, but concerned at the same time: sure, it had enormous potential, but in order to realize it, it needed to involve more people, not only developers but as many people as possible in the general population. And that's why he created the ChainSkills initiative with his friend Said Eloudrhiri, and started giving conferences everywhere, producing online courses with more than 10,000 students and writing books about it. Today, in addition to all of that, Sebastien still develops mobile, web and backend applications for corporate customers and produces a French-speaking podcast, the ProofOfCast, about crypto-currencies, blockchain and decentralization, all the while travelling the world as a digital nomad.
Since the beginning of his career in 1992, Said has been involved in several projects as a developer, software architect, team leader or agile coach. This long experience let him identify the potential of some promising technologies while learning how to use them. As a speaker, Said loves to share his experience on different fields such as mobile and web development, agile methodologies or the blockchain. The Ethereum blockchain is one of these promising technologies in which Said is now very involved. Said co-founded ChainSkills with his friend Sébastien Arbogast. This initiative aims at educating managers and developers about the power and techniques of open blockchains as a development platform. They created a course on Udemy and talked about Ethereum in several conferences. Last but not least, Said is a husband and a proud father of three kids.
