Gives a good basic knowledge of how cryptocurrency works. Assigments were interesting, although in my opinion the first one could have a better description. I liked the grading system. Would be great if there were more of those assignments.

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.

Overall it is a very detailed course. A bit though sometimes to follow. At least I needed to view more than once many parts of quite some videos. Apart from that, it gave me quite some good knowledge about Bitcoin and Blockchain

Great course overall, my only complaint is that there are a few bugs on the assignment test scripts that makes it difficult to debug your assignments since you don't have access to the test code. Barring that course is 5/5

Very good course and good material.

The programming exercises are not too difficult, but the code setup given is not very easy to get into, and could use a clearer purpose and direction.

Could do with a credit exam as well.

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

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!

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.

Learned a lot about Bitcoin and cryptocurrencies. Struggled with the Java exercises; I am not a programmer. Struggled with crafting local test harnesses for the code and resolving Java exceptions.

The coding exercise required a bit of time to fully comprehend. Other than that, it was pretty helpful for a beginner to get into the world of Crypocurrency and the foundation theory of Bitcoin.

Interesting course. Good points: material is interesting and comprehensive, lecturers are knowledgeable. Not so good points: assignment specifications and test code is poor (or non-existent).

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

The theory part is quite good: you get a rather strong in-detail understanding of the technology behind Bitcoin. The Java programming assignments, however, are an organizational disaster.

There is quite a bit of material within this course. Having the supplementary book and Princeton online material helped substantially especially when debugging the assignments.

I feel this course to be very interesting. However, the programming tasks can be a little bit difficult to understand, thanks to the debate forums that was much easier. Thanks

Good course but I found it a little difficult to follow. The prof. speaks very fast. It becomes a little uneasy to follow the slides and I need to pause the video frequently.

Would have been much better if more coding problems & assignments were there in Python similar to Udacity.

Current course is more of theory based rather than practical.

Great course the amount of info i learnt from this as well as the cryptocurrency talks @thebandwidthbarn makes this worth while, note you need some java dev skills

Assignment code is a little unclear, and could be better documented, providing unit tests to the students could also help improve the quality of the submissions

Somewhat dated material, and some decidedly poorly written assignments. However, all in all, a very interesting class with some great, well taught fundamentals.

Great content but if you don't know how to code it's very difficult given direction given on the assignments. Need to have some computer science background.

Very good introduction into blockchain technology. Unfortunately no certificate and completion requires Java programming skills. Also a bit outdated (2018).

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

The course was good. If you want to start with the bitcoin & Co this is one course to start with.

I wish that the code exercises will be more elaborated.

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 !
