I find this course prepared very well. There are many perspectives and this course does not concentrate on the technology only. I find this course very helpful. The level is more then just beginner.

Needlessly difficult programming assignments, because no tests or main functions were provided. We were left to guess what was expected in a painful, slow, feedback loop of submitting to the grader, waiting several minutes for it to complete, and looking at errors to guess what might have happened. If we could compile and run locally, or (GASP!) were even provided with the tests and expected outputs (e.g., like with the Stanford Machine Learning course), the pain of the programming would have been removed, allowing us to focus on learning the material, instead of blindly guessing what was being tested and/or passed in to functions.

no certificate

Loved this course! It was very thorough. However I think assignments could have been made more clearer as it was often hard to figure out what needed to be done without checking discussion forums.

Course content good but labs difficult to work with as no offline unit tests were provided which made debugging painful.

It's literally a miracle that Coursera allows me to study from perhaps the best professors on blockchain in the world.

For FREE.

It's not a joke how big of an opportunity this is. And although I'm not into college yet, and even though I don't even plan to opt for a STEM major, I do have a basic knowledge of programming and I'm going to try my best to make the most of this god-send gift.

Thank you sooooooo much. I love you guys :)

The method of teaching is just amazing. Great content and information. Just loved it!!

Enjoying it. Good lectures and books. Lectures are based on 2015-2015 data on bitcoin and crypto-currencies space. This technology is changing rapidly. Would like see the course materials/lectures updated with latest data.Thank you!

Sometimes assignments not so explicit. Would be a plus to be able to run some unit tests locally.

Inattentive lectures. There're only a few videos that are worth watching. You need to be prepared for wasting a lot of time for programming assignments -- it's not because the assignments are tough but because of poor descriptions and out of sync with lectures. If you're interested, just download the online material (not videos) and read through it. Much better than wasting your time with the lecture videos and assignments.

Good course

The class is very good.nice teacher！

overall great learning material

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!

Very well organized course about this fascinating technology!

It is good course with clear technical concepts

Good foundational material! I look forward to continuing my studies with the text book.

this course is really useful,and i believe the block chain will be more well-known in the future

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.

Solid amount of knowledge presented in clear and concise way. Some basic Java experience is required those who want to pass the assignments.

Intensive and complete, with many examples and professionals who really know what they are talking about. Highly recommend.

Excellent course but we should update the material every year

Why is this marked as complete there are more weeks of lectures?
