Very good!

Great course to understand how Bitcoin (and Blockchain networks) works

A very detailed and rigorous course. Simply loved it!

confusing for beginners, it's best to start from practice then theory. if only theory is very confusing

A very good course.

a

The best course ever!

Excellent course by the Princeton University!

I have been studying blockchain in order to better understanding its potential paradigm shifts and was somewhat discouraged at first by the course's focus on specifically Bitcoin and Cryptocurrencies, but am happy to say that it fulfilled my expectations on explaining decentralized ledgers of trust (i.e. blockchain itself) in broader terms, along with alternate use cases and implications for the future.

Very complete conceptually and technically. The assignments delve into Java code and greatly add to technically understand the intricacies of the subject, but aren't really necessary for grasping a conceptual understanding of the matter (for programmers or those who can manage their way into code, though, they're definitely worth going through!).

Congratulations to Coursera and the Princeton University for making available a course as good as this for free!

Excellent course !

Very good and complete course

Informational, with hands-on experience. Educates pretty well on the technical details. Also addresses some FAQs if cryptocurrency is new to you.

Curso muito bom,a unica crítica é a questão das legendas,poderiam ter mais opções como em espanhol por exemplo.

This course has open my eye more on my new career is a bit stronge for beginners but you fit in into new world of global economy.

Comprehensive and interesting course, covering BitCoin related topics in an easy to comprehend way.

One thing that can be improved are programming assignements - it would be much easier if there would be project (Eclipse, IntelliJ, maven, ...) and unit tests provided.

Very nice course. I would have appreciate a treatment slightly more mathematical, but overall it is a great course.

Good course but some of the material is out of date using 2014 data.

The course should be updated!

Great course to learn how cryptocurrencies work. Not only theory but programming assignments. Great!

Good course, but without Certificates!

Excellent material for those that want introduction to the world of Bitcoin and other Blockchain technologies.

I think this course should include more assignments.

Love this course! The lectures were outstanding. I took one star off for the programming assignments. There is much wasted time required. No test framework is given that allows developing code outside of the grader. And trying to debug code by submitting to the grader is difficult and time consuming.

Liked it very much. The exercises, however, could be better explained in some parts

Course is good. Content wasn't updated after its initial run in 2014, so doesn't include recent developments. Could include a section on ethereum. Programming exercises could be structure better and unit tests could be exposed to students.

good !!! really enjoyed the programming bits. Also Loved the way crypto-currency economy is introduced, legality and technicality coverage is brilliant !!
