Much Better Alternatives
I would give this half a star or no stars if possible. The course is taught in a way that only shows off the instructor's expertise, instead of focusing on whether the meaning is being conveyed for student understanding. Many of the examples go into extraneous information that the course fails to explain, it assumes students actually understand certain concepts. At other times, it is ambiguous in its explanations. I have taught database systems (Oracle and SQL Server) for over 20 years in Corporate and College environments and you see teachers who want to show off how much they know versus those who really understand students and want students to learn. The former group are usually terrible teachers while the latter are much better teachers. This is also why some textbooks are better than others in similar technical fields. I have found much better alternatives with: 101 Blockchains, Coursera, and Simplilearn. I am part of Blockchain meetup groups and I will make sure to steer them away from this site. If I were to advise this site, I would suggest they have introductory courses in Blockchain that explain certain concepts in greater detail and that stay on the point.
