This course is really a good start to understand basic of blockchain and cryptocurrencies. Since the course is quite old, after finish this course, I would recommend to study more in other resources.

This is a very detailed course for someone enough curious to start the Blockchain path. This content quality is very good and the information is transmited on a very effecient and profecient way.

It definitely triggered some interest in a new (for me) area!
Some of the explanations could have been a bit clearer, but it is still worthwhile to take the course.
What I did miss is the interaction in the discussion forums. Which is a contributing factor for not going for the full specialization, although most of it because I have previous experience...

The course provides a great insight into the Blockchain technology and different popular blockchain technologies available in the market. It also provides an overview on how the world will evolve with the increased use of Blockchain and scope for different business models etc. It is good course to venture into blockcha

The content seems a little outdated because there has been a lot of progress made in the blockchain and cryptocurrency arena which is not covered in this course. Other than that the instructor and the course is wonderful.

Great course, plenty of information. I recommend to have a small idea on blockchain before taking this course because they allocate too little time for the basics

As the title says it should have more emphasized on the business and doing it real world , but it is still a good course to understand the blockchain.

This was supposed to be an intermediate course that focused on blockchain business models, but instead, focused mainly on such general blockchain information that was very unspecific to the subject it was supposed to be about. As someone already very knowledgeable about BTC, ETH, and how blockchain tech works, less than 20% of this course was new, useful information. I wanted to do a deep dive on the industry use cases but that was only a fraction of this course and did not go into real depth. Quite disappointed. The Duke courses on decentralized finance were way better.

Instructor spoke too slowly. I solved that by using 1.5 speed. Also, the working of the tests were poor. I had to retake three of eight tests multiple times to pass, simply because the test question descriptions didn't match the instructor description of the materials at times. I retook three tests at least three times each. That's not me failing tests, that's these tests were not well done.

The course was very well taught. However, the course content can be improved further by including more about implentation examples and challenges in businesses such as supply chain management. Also, the focus on regulatory laws can be reduced because they are highly country specific.

Somewhat too US-centric towards the end. But otherwise great stuff!

Okay material. Teacher was difficult to listen to for extended periods. Emphasis did match the true important segments of the material. A bit long for the content.

Good syllabus. The lecturer communicates clearly in terms of phonetics. He should improve on his explanation of contents including the key concepts.

Terrible course, it has absolutely nothing to do with the scope of the specialization (finance and strategy). The course goes entirely in boring, unintelligible and useless technicalities and computer concepts together with explaining the operation of programs and algorithms being suitable for a specialization in computer subjects but not for a program with a focus on finance and strategy. Duke must solve this type of errors since it puts its prestige at stake, it should eliminate this course from the specialization, or change the focus, lessons, tests and content towards a more practical and useful profile (show examples of practical uses of the technology and the potential business it can generate).

major problems in the grade section. some quizzes, tests or exams did NOT have a clear answer!! moreover a true/false question turned out wrong in both attempts - one time the answer true one time the answer false . please test and consider reconfiguration.

A largely incoherent mess. This course belabours many easy to grasp concepts in a scattergun approach but then airdrops references to irrelevant and complex notions. Its nether well thought out nor well targeted to any particular audience.
