Good material but course is not taught well

The explanations were rather superficial.

its good to knowinng about the blockchain

Good content but lectures are too short.

course in well but need more explanation

Its very basic without much hands-on.

Basics needed for the course.

Could have been more detailed

Good experience as a beginner.

no programming.. very basic

It quite hard to understand

Maybe too high level for me

nice course for beginner

Ok, it's a good overview

It's a good course.

... Too simple

Basics only

Good

good

After terminating another Coursera course (Applied Machine Learning in Python) which I found too difficult to be considered a medium difficult course, I found this one too easy.

Also, I didn't like the mixture between very short videos with a - sorry - strange tutor that most of the time didn't look at you (because of the camera angle, I found this very disturbing) and a whole bunch of reading material where a lot of the links didn't work anymore. It gave me the impression, that this course has been compiled without putting very much effort into it and there is no regular checking whether the linked material is still available.

The tests were a joke, they often just had 3 or 4 questions.

Then - in the final "programming exercise" you had to install a virtual box in the commercial software VirtualBox. VirtualBox as a prerequisite to successfully complete this course was never mentioned in any of the previous sessions. Luckily I already had a working VirtualBox installation on my private PC. (On my company PC, the admins would never install VirtualBox due to security reasons.) It would have been very frustrating if I had found out in week 4 that I was not able to complete the course. At least the environment in that "Ethereum" virtual machine was working fine and was very convinient to use.

If your going to have someone just read an English script, why select someone who you can't understand? It's extremely frustrating. Videos are incomprehensible and it goes from 0-100 extremally quick. Download the suggested reading material first and study it before going to the videos. I ended up just re-typing the video scripts and reading them myself instead of trying to comprehend the reader. This course explains everything you need to know about the blockchain, but you have to do a lot of work to put it in order and actually understand what their trying to explain. It's obvious that that there was no case studies on how effective this course was put together or arranged before making it public. I gave it two stars instead of one, only because the material is there, its just a mess for the user to decipher it all. If the course instructor could speak clear and concise English, I would of bumped this up to 4 stars.

This is a good attempt of an online course. There were lots of broken links on the reading information. In addition, I saw many questions that are not answered by the course moderators. Furthermore, the last part of the course which was the final assignment was methodical in the first part but after that, the information was not provided on what to do next, so I had to relay on my background information to finish the assignment, which is not the correct methodology in my opinion for a fair evaluation. Minor improvement is required in my opinion. Thank you for the information and good luck.

I'm writing this review prior to completing module 4. The videos are quite short and technical, a lot of the extra reading contains additional explanation and examples...that is, if the links work. About half the links provided are no longer available. In the week 3 evaluation you are required to calculate a hash, but the link to the information needed for the calculation does not function. The course explains ETH still being on a proof of work basis, but at this moment it is proof of stake. It appears this course is older and needs revising!

I often found the instructor overexplained obvious high level elements but the explanation for topics that require good explanations were unclear. For example, 'Securing Blockchain' (week 3) video was incomprehensible to me. Example 2 could be the Robustness video which didn't explain well how the longest chain wins solution works which is what the video is really about. The instructor ofen just reads out the slides. The resources are a collection of links. The standard of this course is lower than usual for Coursera.

Lessons take 10 minutes only and students have to ready everything by them self. Video lessons are not enough to give a good understand of the topic (they shouldI

99% of the time is spent reading documentation and paper (no written by Professor). Time to read documentation is under estimated. Usually a course helps to speed-up the learning process. That's not the case of this course.

The list of documentation is enough, in this case Professor support (lessons) is useless.
