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? (-:

Finally I completed this course, it takes more effort than I thought. Through this course, I get familiar with the basic and advance concepts of the bitcoin, blockchain and somehow the whole cryptocurrency, I learned a lots form it. Beginning at the second half of 2018, I became a programmer in blockchain field, hope the blockchain tech grow more rapidly and play a more important role in the future.

I'm very pleased such an important course for nowadays can be found on your platform. Easy to absorb the high quality information from great professors and their associates. Another not less important advantage is you do not have to worry about the source and information accuracy which makes the course thrustful for 100%. Thanks a lot for education and doing this world better!

From technology to economics and politics, every related perspective are covered in this amazing course.
However, I see a big gap between "finish the course with 100% points" and "being able to read Bitcoin Core source code". I hope another hardcore course could cover this gap.
Thanks for all the instructors, forum mentors and whoever contributed to this course.

The course and the teachers are amazing. I learned a lot of new things about the Blockchain technology and I also learned many things from the assignments. You should include more assignments in the future. It would be very constructive if you can create some suggestive diagrams in the assignments and if you can present the results for some simple test cases.

Despite some issues with the automated grading of programming assignments this course was a great immersion into Bitcoin, surrounding technologies, and research areas. It is a great foundational course that prepares the student for many possible career opportunities as well as advanced studies in the field. The textbook is outstanding as are the lectures.

It was one of the best courses I've ever done. The lectures were prepared very well and gave a broad a well as close view of bitcoin and cryptocurrencies. The assignments were fun to complete. I enjoyed doing this course a lot. The one thing to complain is, the lectures are from 2014 and there were certain updates in cryptocurrencies in those 4 years.

Great course. Love to see more of this material.
Please find my promotion for it here on the first blockchain based social network:
If you want to donate Bitcoins for me to write further blog posts:

Very well explanation of Blockchain and underlying consensus mechanisms.
The only right information available on the web about Blockchain. Others are just creating hype around technology.
However, one thing to suggest is that the title of this course is misleading. You should keep the title related to Blockchain instead of Cryptocurrencies.

This is so far the only openly available course on blockchain fundamentals from a reputable university. It was a comprehensive introduction into crypto technologies. The minor drawbacks of the course were the exclusive use of Java for the programming assignments and the fact that the material was not updated from the year 2015.

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!

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.

Absolutely fantastic course with a lot of useful information and interesting details related to the topic. Programming assignments are quite good as well. Definitely worth studying if you are interested in cryptocurrencies and blockchain technology.
