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.

Lectures are excellent! The complex things are explained quite simple and it was easy to me to understand the material. But I am not sutisfied with assignments. It was really hard to understand what should be implemented and how it should work. Thank you for the course!

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.

My previous course Basic of blockchain help me a lot to crack this course. all assignments are very difficult but provided code will help us to solve the rest of implementation. as i am teaching java since last 7 years it is difficult to find solution of some code.

Great course about crypto-currency. With technical detail understanding and non-technical (ethical,...) considerations. If I may, I feel the assignments may be a turn-off for people that don't know how to code (Java) and assignments explainations could be improved.

Well structured, good explanations. Tests require java programming skills, could be a good idea to divide them into smaller pieces and combine them with other type of tests, so they can be distributed every other week instead of having 3 big programming exercises.

Havent done any programming part as it was too technical for me.Also was lost in same parts. But generally it is a great introduction. The biggets problem i see is that its developing so fast that it would need to do updates of the course almost every year

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.

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.
