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.

The course is comprehensive and covers technical, social, economic. legal aspects of Bitcoin. The technical treatment is hands on and gives a really good fell for how bitcoin and blockchain works compared to several other sources where treatment is superficial.
There are several parts of the course I was not able to get a clear understanding - such as implementation of the actual bitcoin core in the stack based script. Also I found the questions for the programming assignments convoluted and not very helpful in describing what is required from the student. Had it not been for discussions on the student forum I would not have been able to complete the final assignment.
Despite the shortcomings I would recommend this for someone who is good in Java and would like to get a technical as well as comprehensive understanding of cryptocurrencies and blockchain.

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.

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.

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?

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.

This course was a little too advanced for me and not quite what I had in mind.

Not efficient use of slides and real time explanation using hand

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

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.

Too fast not spending enough time on the concepts
Dec 29, 2017
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.

Very outdated.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