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? (-:

A LOT of information. It put a lot of the technology into perspective. Definitely worth the time if you're trying to pick up some knowledge.
If I had one criticism, it is that some of the stuff included is already dated. Which is bound to happen with tech that moves so fast.

This is a great course loaded with solid knowledge. It addressed many of my questions and concerns about cryptocurrency. Also gave me some hands-on experience via homework. I deeply appreciate that this is offered on Coursera. I wish I had known of this class earlier.

Excellent course: well organized, lectures well presented, additional material very appropriate. Personally, I did not bother taking the time to do any of the assignments. Even without the glory of the grade, it was one of the most interesting courses taken online.

Absolutely amazing. I think any academic who wants to start writing about blockchain and comes from a discipline different than computer science or mathematics should watch this as a prerequisite. Thank you for putting this wonderful and free resource together!

Exceptionally detailed introduction to Bitcoin. The exercises were thought provoking and helped understand the bitcoin mechanics and the problems the Bitcoin creators needed to solve. The exercises are however tough without easy access to a testing harness.

The videos are very clear and easy to understand. The quality of the material is very good. Personally, I like in-depth materials and I believe this course has the right level for what I´ve looking for regarding bitcoin knowledge. Congrats!

Excellent content. My only gripe is that the programming assignments seem to require intermediate level understanding of OOP and Java, but not being able to complete those assignments doesn't really take away from the benefit of the course.

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.

Amazing course! Before taking this course, I have already read some articles about Bitcoins details and I think I have already known much about Bitcoins, but during the lectures I realized that I misunderstood many things about Bitcoins!

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.

High Level JAVA mapping exercises really energized my brain to understand concepts of bitcoins and blockChains. Perfect course to summarize cryptocurrency and also guides you perfectly in using blockchain code in other domains too.

The best bitcoin course I have found on the internet to date.
Great way to understand the thoughts behind bitcoin technologies.
The authors have found a perfect balance to cover wide range of subjects and getting deep into details.

The course is quite great! At least I wouldn't be silly when talking about the Bitcoin stuff. However, students like me who don't have any previous knowledge about crypto technologies should first read through the text book.....

This is a very good overview course for Bitcoin and underlying blockchain and crypto technology - along with homework that is difficult enough to force one to think a bit and review your java skills. Appreciated and enjoyed.

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!

This course is somehow old 2014, but completely shows the how the bitcoin works, and in fact how crypto currencies work in general. They have an awesome chapter about anonymity. Extra material weeks are really good.

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.

With how rapidly cryptocurrency technology changes, I think the course should be updated (or at least addendum lectures added where appropriate). But this was quite comprehensive and fantastic for a free course!

I mine ETH for a very small profit, but this course opened my eyes to many of the awesome inner workings of cryptocurrencies. The professors are very well spoken and the content is intuitively structured!

Excellent course! It not only covers the technical part of bitcoin and cryptocurrency, but also contains a lot of very inspiring discussions about its relation to the real world. I learnt so much from it!
