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? (-:

It gives a very throrough insight about most of the aspects of cryptocurrencies and dive into a bit of detail of the implementation of parts of the technology. It does not get at the maximum level of detail, technology-wide (for example, explaining every field or function or process related to Bitcoin internal workings).

Great course. All the information is delivered in a clear and understandable way. The course covered much more topics than I expected. When I first started this course I was hesitant I only wished to learn about cryptocurrencies because it's an important topic, but after a few lectures I was very excited to learn more.

Excellent course! Really liked that it was not very micro detail oriented. The emphasis was more about the concept and potentials and it gave a good motivation to look up some details on the Web. From here it is quite easy to submerge into the implementation if somebody is interested. I highly recommend this course.

Great course, definitely a complete introduction to crypto-currencies.
Lectures are great and assignments interesting and insightful.
Keep them coming !!!
I would have only one recommendation: Try making a certificate course, and for example, the final exam would be to create a simplified cyptocurrency from scratch :)

Very nice course. Everything explained very detailed with examples and of course most important practice problems to program by myself so that I can remember the principles of work of ScroogeCoin system data validation. The one thing I miss is that I am unable to choose another programming language instead of Java

good lectures and programming assignments to unterstand the basics of bitcoin and blockchain technology. of course it is hard to keep the course up to date althogh probably this course is still one of the best resources to learn bitcoin/blockchain technology for people with basic programming skills in Java.

I really liked the course, I am currently a full-time online student and I seek to enroll in other helpful and very interesting courses that I can actually feel that I can get use of in the future and this course was exactly that. The coding assignments were hard, but very fun, and I learned a lot from them.

Good oversight of the ideas of crypto currencies in general and many details about BitCoin in special. The programming assignments gave me a good impression about the technical considerations in order to establish distributed consensus.
A mostly fascinating topic presented in a mostly usable way.

Course on Latest topic - cryptocurrency. Very nice lectures, and very well organized. I had only heard the term bitcoin but got to know the math, protocols, and technology behind it from this course.
Thanks you for putting this course.
Thanks to Prof. Felton, Prof Arvind Narayanan. Great videos.

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!

This course covers all aspects of blockchain technology and help you understands not only basic concepts but advanced and more complex concepts in cryptocurrency. The proposed reading book is very important and will give you more details and more exercises .

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.

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.
