No practical tutorials and tasks. Only theory and understanding are not enough to learn security properly.

I learned so much during this course. The course designer and instructor, Howard Poston, was easy to follow and provided valuable diagrams during his video descriptions of the blockchain security issues discussed in this course. While much of the material was complicated and it was covered in a short time, I think this course gives a great overview of the most common issues regarding blockchain security, without being overly brief or going into too much detail. I would recommend this course to everyone interested in blockchain security.
