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.

Great introductory class. It is very clear, and teacher was wise to give his opinion only in the last lecture. Even though this class took place in 2015, it already spoke about Ethereum and Ripple which are now widely used and recognized, strengthening trust in the opinion and skills of the teachers.
Programming exercices could be redone because a lot of time is passed trying to guess the logic of the code instead of having a practical understanding of blockchain technologies.

A little dated (2014) and not enough technical detail, coverage a little too broad. Java homework exercises are great, though

A good general introduction to bitcoin, and blockchain technology. Unfortunately, this is a very fast moving area and so a course which hasn't been updated since 2015 is fairly out of date now. However, the basic ideas haven't changed so that's valuable. The thinking about where bitcoin, and block chain technology in general, are heading, has moved on a lot - we've had hard forks, bitlicenses were introduced, and the value of a bitcoin topped $8000 this week.
I'm not a software engineer, so I didn't do the programming assignments, just watched the videos and read around the topic. That worked well, and to some extent the fact that it is so out of date means that I was forced to go and look stuff up, which meant I learned more.

It was very hard to figure out what is required to complete assessment tasks.
I did't find much correlation between lectures and practical tasks.

It's a good course to get a grip on the fundamentals of cryptocurrency, beyond pure technology.
But the content must be updated, and practices are no well designed according to the flow of the course.

A good introduction, but could be better. The assignments' code is poorly documented and the assignments themselves are not clear.

Some of the lectures provided interesting and useful content. Others seemed to just be filling time. I was hoping for more of a technical exploration of Bitcoin and other significant cryptocurrencies. This course focuses almost completely on Bitcoin. It also speaks to cryptocurrencies in general, but give no in-depth treatment to any other cryptocurrency. Although it was not what I had hoped for, I did appreciate the wide breadth of Bitcoin related topics. This course provides a significant amount of material to digest for anybody who wants to contemplate how cryptocurrencies and other uses of block-chain technologies might continue to impact our society.
The lab assignments were extremely disappointing. The first lab has enormous potential, but the instructions are awful. The second lab is an interesting idea, but the instructions are even worse than the first lab. I'm guessing that somebody's grad students were tasked with developing the lab assignments, and the second lab was left unfinished when a student decided to leave academia to take a job with Uber. The third lab did not add much to the course.

The course is good because it covers all areas about bitcon technology, block chain and decentralisation from the past to the future. The assignments are also very useful for enhance our understanding to the basic concepts and course materials. However, it would be better if slides can be shown for a longer time in the videos while instructors are explaining, since some of the students are not English native who may need more time to read the slides (without pausing the video). Thanks all instructors, mentors, and coursera staff for providing this high quality online course.

I love the assignments (better than any other classes I knew) but the instructions and also helps weren't clear.
The materials are a bit out-dated. Some of the materials from Week 8 aren't useful.

Good introduction to blockchain and cryptocurrency, simple and to the roots, to start to know.

Great overview of Bitcoin, solid foundation in Blockchain. This industry is fast moving so its a bit dated with its content -- for example, this was done before Ethereum so it is not mentioned at all. Needs to be updated. Plus -- no certificate dings it one more for me...

Contents are referred to 2014 status of bitcoin and of the related topics.

Most lectures were good, but the assignments are terrible. None of the assignments comes with code comes with tests to run on your own computer, which means that you have to turn the code in to run it. This means that prints and asserts does not work and the only way I could debug was with exceptions. The assignments are poorly described as well.

1 Very poor preparation of programming assignments
2 Poor preparation of video content (like switching to video from camera just to demonstrate laser pointer)

Good information even if it could be explained in a better manner. The labs are very poorly designed with vague requirements and poor grading logic.

Great course material (although it does need a few updates), good lecturers, and gives a very good overview of how Bitcoin and cryptocurrencies in general operate. The assignments however are of a difficulty level completely different to the lectures and quizzes! Much of the resources needed to complete assignments is not in the lectures or other source material, or is only hinted at but not explained in the necessary detail. Java programming experience is a must as non-trivial classes and code are provided as the starting point for assignments.
I thoroughly enjoyed the course, but the assignments did not seem to be on par with the rest of the course material.

The course is great!
The teachers very prepared, but there are some things to change like, for example, the assignments (that are difficult and not consistent with the contents of the course) and some contents that, nowadays, are partly obsolete.
