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? (-:

Though there are many blockchain products out there, it is always good to start from the first cryptocurrency, Bitcoin. The programming assignments are very good to understand the tech details under the ground. I wish the course can be updated with more recentcurrencies such as ETH.

The only downside of this course is Java.

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.

This course is a very good introduction to blockchain technology and popular in nowadays Bitcoin currency. However the main disadvantages are assigments which are hard to accomplished because there aren't any tests attached, so you cannot check on your computer whether your solution is good or not and you cannot debug your code to find an issue if it isn't ;)

The content and videos are good, but the programming assignments could really use some work to make them easier to understand and implement.

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).

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.

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.

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

There is a lot of going on in this space nowadays, would be nice to add new videos to cover the latest developments.
I found myself spending more than 3 hours for each assessment. Maybe adding a video with a description of the assessment would clarify the problem we are trying to solve.

Should be updated a bit, but still entirely worthwhile - especially for newbies.

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

The course was really helpful.
Considering the fact that I was not from security background, it went very smoothly

Excellent course overall. A little out of date (hard to remain totally timely given how fast the space is moving) but the fundamentals are there. The problem sets are not the best thought through in my opinion. If you want to learn the fundamentals of blockchain technology and bitcoin, however, I heartily recommend.

The instructor teaches with ample examples. The pace is appropriate.
A few more illustrated examples or sample hash functions (in java) or other that we could run to check the verify functions for instance can greatly help as well.
Sure, we can do those on our own. But the best practices or some logical errors that we are unaware of may creep in and can be avoided.

A bit dated now but a good course. There should be an option to turn off the programming assignments requirement; given that in the introduction the course coordinator explains that programming and doing the programming assignments is not required.

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

Excellent course!. Just 4 stars because it is becoming a bit outdated. Blockchain frenzy is to be blamed, not the teachers ;-)

The only reason I do not give a better grade, is that assignments should have a better documentation and also more context should be provided to the student (at least on the first assignment, where the terms used on the description and in the code weren't yet discussed in the video lessons).

Overall it is a great course. Just think that the assignment could have been break into many smaller sections with a slower learning curve.

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

The video lectures were perfect. I got a comprehensive insight into the facinating world of cryptocurrencies and blockchain. I also liked the assignments. I am a professional software developer/engineer. They were very challenging and really make you dig deep into the topic and get a practical feeling for the whole thing. However I didnt like the way the programming assignments were structured and the way they were explained. There is 3 assignments scattered over the course, with completely different skill levels. First assignment is very long complex and covers way too much for one assignment. If I didnt have much experience as software developer in Java it wouldve been impossible to get anything done I think. However with my background I liked the challenge. Also the assignments should have basic tests included in junit. I had to write those myself to get a descent feedback loop. There is some repo by the mentors but it lacks a lot of parts. The second assignment is way to short and simple compared to the first one. The third one is ok in length. However I think it wouldve been better to have more asignments with smaller steps but digging more into one specific topic. As I said I personally had fun doing them. Would be cool if you guys made a follow up course maybe digging deeper into the topics. THanks for doing this. Also I think there is no certificate, there should be some kind of certificate to grade the work that the strudents put in.

Extremely good course. Only drawback is that the assignments cannot really be checked independently.
