Great course on Enterprise Blockchain. Fundamentals and real world examples. A great start for anybody interested in business possibilities, and not just the cryptocurrency aspects of blockchain. It explains the subjects with real world examples, which is an excellent way to get the necessary information across. Also covers aspects about governance and ecosystems. Really useful.

The infographics are great and make the audio discussion easy to follow. Short course is very logically organised, and is of interest to anyone who wants to learn more about this technology that is likely to change business operations, and the way consumers conduct business.

This course is the most extensive and up-to-date course on Blockchain that I have found. I highly recommend the Enterprise Blockchain Professional course because it is tailored to the interests of business professionals at all levels of an enterprise, including the C-suite. The course curriculum is current and well thought-out and provides the right balance between technical content and business applications. The added value to my career is significant.

As a product manager, this course helped me lead a new innovative product that utilizes blockchain technology. If you want to get into blockchain technology and business, you definitely have to take courses like these. Unfortunately, universities do not teach you this stuff, so you have to take courses like these where you can learn from professional experts. Highly recommend
