As a new user to blockchain, I was able to listen with great interest and enjoyment. I liked the clear explanation of how blockchain works in the beginning. I also understood the complicated parts about exchanging private keys, etc. The lecture speed felt a bit fast starting from the middle of the practical training, but the good thing about video lectures is that you can pause them for a while or listen to them repeatedly. So I think I was able to understand them without any shortcomings. I wonder if there will be follow-up lectures. If there are, I definitely want to listen to them. * For reference, I practiced in a Mac OX environment, but I was able to practice without any particular difficulties. I hope this will be helpful to other Mac users.
