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.

Thank you for the pretty detailed introduction into bitcoin's workings and its potential pitfalls and advantages, as well as open questions for blockchain technology and decentralization. Super grateful for all your efforts guys, thanks again.

Altocin chapters are outdated but covered fundamentals still hold true and once you understand Bitcoin well you stand on solid ground and ready to venture out on your own. I highly recommend the course!

Lectures start from very basics of bitcoins and cryptocurrencies and step by step move to very deep information.
It is one of the most usefull and interesting course at Coursera.
Thanks a lot for teachers!

Very good view of blockchain´s system. I´m an economist, so I hadn´t any studies about some technical concepts but this course has been very useful to understand how Bitcoin protocol works.

I really enjoyed the depth of the information in the course and the forward looking view of 'where does bitcoin go from here.'

Good introduction to understand the fundamentals of Bitcoin and other cryptocurrencies.
The assignments in JAVA are quite challenging. They are cleverly chosen so that you can understand the problems under the design of a cryptocurrency.

Very good course - I finally fully understand how bitcoins work!
It would be nice to see this course updated with the recent developments in cryptocurrencies (smart contracts, Ethereum etc.)

An excellent introduction to BitCoin and BlockChain but this is very dated now, the field has been moving really fast since it is quite nascent and I feel this course should have been updated atleast once by now.

This is just an addendum to my previous review. To make every bodies life easier, I would suggest imposing a requirement that all homework be done using Eclipse. It is a popular IDE for Java programming and certainly adequate for this course. Then, I would have the homework cast as an Eclipse Java Project for each assignment. In each raw assignment, include something like theDropBoxTest code that gives a testing framework. Personally, I would do that with a JUNIT style framework. Again, it just makes life easier. You could even bare bones testing assertions and have the students add their own stuff in which is what I eventually wound up doing. The test, themselves show how you expect the whole thing should work.
Then, we students would import the homework as a new project, do what needs to be done and just submit the code developed. The point of including the testing framework is that ambiguities or interpretational variations can much reduced in what we are being asked to do. I found that all my problems pretty much came down to thinking about how I would implement the functionality of the specification quite differently then how it needed to be done to fit into the grading framework. There is really a lot of hidden specification in the grading framework. I could not have done the assignments without the DropBox... framework. The grading process gave very little hints about what might have gone wrong, which is ok for grading, but not so useful for debugging the problem. I think this kind of project approach would reduce a fair amount of the forum questions, and, at the same time, make this course more accessible for Java nubies.

Very detailed inspection of the Blockchain, cryptocurrencies, security, common problems, algorithms and much more like power utilization. Please be aware you need to be fairly familiar with Java if you wish to be successful in this class.

Great course. I appreciated the hands-on experience that the assignments are designed to deliver.
The course is an excellent introduction to cryptocurrencies and the blockchain, and provides plenty of references for further reading. High quality materials (it's a pity that the lecture slides aren't available for separate download, though).
The owners of the course went great lengths to ensure even people without a deep computer science or programming background can avail of the more generic concepts (even though some level of familiarity seems to be implicitly assumed to be able to pass the assignments, which however are optional).
I highly recommend this course.
