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? (-:

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.

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 ;)

This very knowledgeable and informative course, explained with simple examples and language, will give you good understand on Bitcoin and Cryptography.
But I would request to creator if you don’t teach Java Programming in this course, so on what basis to take programming assessments. I believe Programming Assessment should be removed from course ASAP.

Course has very good content and well structured. However it lacks more details on the mechanics, under the hood functioning of Blockchains.
The practical assignments are not adequate. Propose more exercises that goes up in incremental content and difficulties and allow students to get more practical insight upon how a blockchain really works.

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 A little out of date (hard to remain totally timely given how fast the space is moving) but the fundamentals are there.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.

This is a good course if you are an intermediate-level investor. This course will be at a novice level if you have a computer science or cryptography background. Nevertheless, this course should be updated, as many events have happened since this course has been created. This is why I am giving 4/5 stars.

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.

Very good course. The lectures are excellent! Thank-you to the instructors: Andrew, Arvind, Ed and Joseph!
The three assignments are quite challenging, especially assignment #2. Unfortunately, there is a problem with the on-line grader for assignment #2 (see the discussion in the forums).

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).

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.

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.
