Great course, a very broad and in-depth overview of concepts surrounding cryptocurrencies and Bitcoin in particular. Would be great to have an update of course; perhaps once the ICO craze is over? (-:

I've gained a strong knowledge of Bitcoin's architecture but wish this course was updated to include the developments of the last two years. A few lectures on alt-coins would have been useful as well.

1 Very poor preparation of programming assignments
2 Poor preparation of video content (like switching to video from camera just to demonstrate laser pointer)

Assignments would need to be improved...

I love the assignments (better than any other classes I knew) but the instructions and also helps weren't clear.
The materials are a bit out-dated. Some of the materials from Week 8 aren't useful.

Good information even if it could be explained in a better manner. The labs are very poorly designed with vague requirements and poor grading logic.

Great course material (although it does need a few updates), good lecturers, and gives a very good overview of how Bitcoin and cryptocurrencies in general operate. The assignments however are of a difficulty level completely different to the lectures and quizzes! Much of the resources needed to complete assignments is not in the lectures or other source material, or is only hinted at but not explained in the necessary detail. Java programming experience is a must as non-trivial classes and code are provided as the starting point for assignments.
I thoroughly enjoyed the course, but the assignments did not seem to be on par with the rest of the course material.

I had troubles in understanding assignments. I think they should be more descriptive

A good introduction, but could be better. The assignments' code is poorly documented and the assignments themselves are not clear.

Most lectures were good, but the assignments are terrible. None of the assignments comes with code comes with tests to run on your own computer, which means that you have to turn the code in to run it. This means that prints and asserts does not work and the only way I could debug was with exceptions. The assignments are poorly described as well.

Great course , very informative and a good general introduction to bitcoin, and blockchain technology Thanks for lecturers highly recommended.

The theoretical content of the course is interesting and it gives an excellent overview of the cryptocurrency technologies through the example of bitcoin. The course also extend to alt coins and the discuss the possible challenge blockchains can help addressing beyond the purely cryptocurrency field which is interesting.
The programming assignment could however be improved. First they required a strong knowledge of java which can exclude some students. But the real issue is the lack of satisfactory explanations and guidance that sometimes make it impossible to fully resolve the practical, or even what is expected from the student.
Sometimes you can get the best mark while your code is either incorrect or not adressing the logic fully. Sometimes you run into technical limitations on the platform (memory limitation) which despite a good algorithm doesn't allow you to submit your answer. It then forces you to spend time on improving the quality of your code to save the memory used by your program (thus requiring strong java knowledge) which is time consuming and not the purpose of this course.
Overall I would advise to do the course. I would however strongly encourage Coursera/Princeton to review the assignments so that they can best help students in the understanding of the complex notions discussed in this course.

Data from 2014 isn't useful in today's environment. Although fundamentals are clearly valid tpday, an update to course is mandatory

This was a tedious and boring course! the assignments were impossible to decipher and I fail to see the end result of the point of the coins. Wouldn't it make more sense to have some form of physical currency or bartering instead?

Lectures were extremely good, but assignments and graders were very low quality and difficult to decipher requirements from. Professors and TAs were not active in the forums.

The course covered a lot of things, but the programming assessments are very poor. In first the assessments the bonus task is basically not about blockchain, but rather about graphs. I would recommend adding to course more small coding assignments to get familiar with blockchain and bitcoin platform in a more practical way.

Very outdated. Since 2014 the content about fees, mining, forks, etc change a lot

I saw initially in the comment section about the course that it talked about Java a bit, but I was under the impression that we would only be discussing it, not throwing some code together for our first assignment. I know the basics for Python, HTML, and CSS, but I really don't have time to learn Java just to pass this class. I was hoping the class would be more about the basics of cryptocurrency so I could have a better understanding for it. I'm extremely disappointed.

Difficult to understand. Teachers were too stiff and not very warm to explain. Concepts were too technical and sometimes was difficult to understand the general ideas. Assignments were not very good explained and it was difficult to understand and the errors were not very helpful.

I think that it would be a good idea to improve the grader, release more informative assignment information (take a look at the Algorithms course for example) and lecture materials in pdf format.

Not a big fan of this course. I wanted to learn about the different types of currencies and their usage, but these guys go way too deep into the code structure, even making the 1st assignment code based. Just because I am interested in cars, doesn't mean I necessarily have to know how to build one. I merely need to know some base facts, it's safety, handling, fuel economy, size etc. Their approach is way more mundane and impractical for daily needs of working with Cryptocurrencies, going way too deep into early theory and applications.
