Great course. Very well explained topics. The only criticism would be on lack of tests in coding tasks, and only one language supported. (Java)

Things are good except the assignments, which is hard to get started.

The tasks could have been broken in smaller pieces to make them more understandable. Course material (Videos) are understandable.

The knowledge provided is very elaborated and useful for understanding Bit coin an its security.

Very informative and detailed. Little bit outdated so I can't wait for the new version.

muy educativo para aprender a minar

The videos are very informative and I learned a lot from it. The information in the later weeks is outdated. An update about legislation, altcoins and the future of Bitcoin is needed. I would have given this course 5 stars, if it wasn't for the difficult programming exercises. There is very little feedback on these exercises. If I didn't have a friend who had done the course already and knows Java very well, it would have been very difficult to pass this course. That's why I deduct 1 star. I say again, the course is excellent to get in-dept understanding of Bitcoin and cryptocurrency. Thank you for making this course. Too bad I can't get a certificate.

Thorough overview of relevant topics.

Very useful information about bitcoin and blockchain in general.

The assignments needs improving, more clarification and testing files(input files) are needed to help students.

Not as technical as I have thought at the first sight, but still gives pretty deep insight into the field considering the course was taught 3 years ago and the cryptocurrency community has undergone a massive change!

Excellent course for a beginner. Highly recommended

Lessons 1- 8interesting and well organised, exercises are hard to nail and require commitment.

Latest part very rushed and superficial, irrelevant

I enjoyed the lecture series. As many have stated previously, I do think that the assignments assume a sizeable amount of technological knowledge that is not necessarily cohesive with the lectures.

Lectures are excellent! The complex things are explained quite simple and it was easy to me to understand the material. But I am not sutisfied with assignments. It was really hard to understand what should be implemented and how it should work. Thank you for the course!

The course has surprised me. I do believe I understand some of it.

I am truly surprised.

A great basic overview of Bitcoin and cryptocurrency.

Great course for understanding bitcoin and cryptocurrencies. The assignment instructions could be more clear. It would be helpful if there was some way to debug code locally before submitting it to prevent wasting time on trivial problems. Otherwise it covers a lot of ground, and I feel I understand the topic at hand from a technical perspective very well now.

too abstract and the ol test is full of bug

A very good introduction to Bitcoin and cryptocurrencies.

Somes parts looked out of date, or at least would need to be update ! Thank you for all that !

Well structured, good explanations. Tests require java programming skills, could be a good idea to divide them into smaller pieces and combine them with other type of tests, so they can be distributed every other week instead of having 3 big programming exercises.

This course gives quick and good insight into crypto currency basics.

should not be based only on java - but should allow pseudo code assignments

Good overview of crypto currency. The programming assignments are interesting (can help if there is some support on the forum). overall good program for someone wanting to learn blockchain

I enjoyed lectures from this course, but assignments were not well discussed in lectures, also the scoring code on coursera server produces some mistakes. All in all, my opinion is that this couse is worth being studied
