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.

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? (-:

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!

This was a great course that gave me introduction to diverse topics ranging from Cryptography, Consensus in distributed systems, blockchains and bitcoin of course. It is true that the course is a bit outdated (from pre Etherium days) however, anyone who wants to have a great understanding of foundations of bitcoin blockchain will still find it useful.
The assignments are designed to test your understanding and I did have to refer to some additional material on bitcoin.org to understand some of the concepts. Also I had to learn Java to complete the assignments. For Java experts, the assignments may not be very tough to deliver.
Lastly, I would like to give a huge shoutout to the mentors. They are very responsive with the questions and the course has a good vibrant discussion forum. You are likely to find answers to all the questions you may have while taking this course.

Even though the course is 5 years old, it is great at covering the inner workings of bitcoin. The programming assignments are sometimes challenging (this is not trivial material in the first place, but also the assignments are not crystal clear, some online graders run out of memory, and a decent knowledge of Java is advisable - I personally did not know Java but know C++ and the programming concepts in both languages are close enough that I could make the transition with reasonable effort). Nevertheless, I find that the assignments are really key to get a good understanding of how bitcoin works. I would strongly advise anyone considering this class to allocate the time to also do the programming assignments, even though they are optional.

I came to this course with more of an interest in blockchain than in the cryptocurrencies which are built on the blockchain technology. That being said, I found this course to be really informative. The Cryptocurrency angle was really helpful in illustrating the basic principles of blockchain. I also found myself much more interested in cryptocurrencies than I thought I was. I have recommended it to colleagues as a fun way to get your head around blockchain basics. I should mention that I really had to reach back to my CS undergrad days to remember Java syntax to completed the assignments! These were fun activities, but I would caution someone with no programming background.

Great course. I appreciated the hands-on experience that the assignments are designed to deliver.
The course is an excellent introduction to cryptocurrencies and the blockchain, and provides plenty of references for further reading. High quality materials (it's a pity that the lecture slides aren't available for separate download, though).
The owners of the course went great lengths to ensure even people without a deep computer science or programming background can avail of the more generic concepts (even though some level of familiarity seems to be implicitly assumed to be able to pass the assignments, which however are optional).
I highly recommend this course.

I tried to learn the concept of bitcoin and browsed several other videos and articles in the Internet. Yet none of them gave me a clear idea of the bitcoin technology and infrastructure. This course give me good understanding of the bitcoin ecosystem. I highly recommend this course.
Something which could be improved are the videos. The videos show the lecturers sometimes and the slides other times. The segments showing the lecturers can be significantly reduced and showing the slides videos only. It is much easier for the students to comprehend the contents in that way. The lecturers videos can be embed as a small block in the slides videos if desired.

Excellent overview of technologies and motivation for how these technologies are being used. Given how time has passed, could be interesting to update some things with current issues such as use of bitcoin/blockchain in many technologies (i.e. what blockchain does & doesn't do), updates to mining efficiency/power consumption/sustainability, use of block chain technologies in industry & startups etc.

Great course. Old, but still valid, specially if you are entering the BTC world and want to know more details. Programming exercises will be difficult for people without dev background... Unfortunately it does not provide a certificate...

This course brings me a lot of information and completely demystifies the subject. In addition, the proposed exercises are excellent and illustrate key concepts of Blockchain. Thanks to the Team for all their efforts!

Meaningful course which gives you the brief idea of what Blockchain is. Although when it's 2020 there are more new initiatives in the blockchain and crypto market. Still a good start for amateurs.
