This course is for everyone who wants to get a firm understanding of the blockchain technology. Whether you are an entrepreneur, investor or developer - the knowledge you will get here will really give you a solid knowledge foundation you can rely upon when navigating the cryptocurrency and blockchain landscape. We will cover how Blockchain and Bitcoin really work under the hood, what Proof of Work and Proof of Stake is, how forks work and much much more. I usually teach this course in seminars and lectures to the highest management of industrial companies, however I think it's important for everyone to understand these concept and ideas. That's the reason I'm now releasing this as a course.
