Quality of recorded lectures is substandard. Most of the reference material are websites which have not necessarily gone through a peer review. Quizzes are trivial. This should not be paid content. It is an equivalent of a youtube / google search on the topic.

Blockchain in itself is a very complex topic to study & teach. I think the material could have been made lore suitable to "laymen" by simplifying the language of delivery, currently it sounds very "academic" and "quoted" from published material, not colloquial. Though the Videos are short, via the reference material too much is being left on the student to "go figure" on their own, I think instead of ref material more stuff could have been included via lectures. The final project was a let-down, it should be more hands-on (for example: why provide a GUI, you could have provided the CLI commands and asked students to execute the commands), it did not really pose the challenge one expects. Even with the GUI, I failed to appreciate the flow that the project was supposed to teach me. Either that or may be at 47 I am getting too old to study :)

the introductory is really, really bad. I went through all the videos and get 100% of the quiz yet I still have ZERO ideas about the overall architecture. Thankfully, I found a website http://learnmeabitcoin.com that gives me a way more comprehensive explanation about blockchain. Why pay $40/mo if I can get a much better resource for free? Moreover, why are there so many people who rate this course 5-star???

Teaching style is not very good. Seems like she's just reading the content and does not have the knowledge herself.

This is an introductory course to Blockchain. The supplemented material (in other words self-study) is excellent and in my opinion is the only way to master the concepts and details of this discipline

such an interesting course but the delivery is so disappointing

Comprehensive and clear course that summarize the basic concepts to understand the blockchain technology. Also the resources and contents included are very valuables. I totally recommend this course.

This course is

a) outdated. All "further reading" links are from 2018, and out of those, half don't even exist anymore.

b) frustrating. The final assignment is run on a Virtualbox VM which you might, or might not get installed on your machine. There are hundreds of graduates-wanna-be that get stranded at this stage because that technology doesn't work on Win10, or on the machine that they have.

The content is fine, but presented in a very old-fashioned way.

I did learn something new (but nothing a bit of googling couldn't have provided), having it presented in a structured format was helpful but i would NEVER recommend this course to anyone.

Disappointed.

Sorry but this is a terrible course. The instructor has zero charisma, reading off an autocue with filmed from weird camera angles. And it's doubly difficult to follow because she has a very strong accent and you need to keep double checking the script text to follow what she is saying. Here we find the grammar and sentence construction is all over the place. typos, missing words, dropped indefinite articles. It's a mess.

The topic list is great - looks really interesting and purports to be exactly what I am looking for - a high level overview of crypto tech, not shying away from the details but not going to a level that a programmer needs to know.

But the implementation is all over the place. Within a lesson, we range from high level concepts to detail that only a engineer needs to know, and back again. I'm a computer science grad and ex-programmer so used to the concepts. But the way it's presented is really hard to follow.

And despite all that crazy detail, many of the actual details needed to answer the quiz questions are not actually covered in the lessons, so you're left guessing or trying to research the answers on the fly during the test. Worse, some of the links to tools that you actually need to use during the test to answer a question are broken.

I think there are great teachers, and great subject matter experts. Sometimes you are lucky and get both. On a virtual teaching course, I believe you minimally need more teaching skills than subject matter skills, since someone else can prepare the material for you. In this case, sadly we've got a complete mishmash.

If you really don't know anything of block chain and want to become a pro who want to actively participate in adoption of the block chain, then this is the course is definitely the stepping stone for you.

The course was really good. Had to do the final in 2 separate computers mac osx and windows. hard to know which one took.. there is no way to interact with the professor??

A comprehensive and clear course that summarizes the basic concepts to understand blockchain technology. Also, the resources and contents included are very valuables. I totally recommend this course.

One of the Best course for Absolutely Beginners :-) Discussed Core Fundamental Factors of Blockchain of Bitcoin and Ethereum. Amazing Resources & Really Helpful Content. Thanks Bina Ramamurthy Ma'am.

I find this course helpful to absolute beginner and for one who wants to grasp the basic concepts of Blockchain . The tutor tried to explain most part with simplicity and good and sufficient details.

Course was great ,no doubt but at last assignment when all virtual setup and installation was required there was no support from either cousera or course provider. People with limitation on installing such software should given alternative of that assignment to get certificate.After 19 hour of learning learner deserved certification should not be taken because he/she does not have environment that suppoet mining of crypto .

.

Poor support in the forums. I had a technical issue with the final project that couldn't solve. After another person and I reported it repeatedly, no tutor replied, thus making us go over the deadline.

Very mechanical delivery, not engaging, and overly simplistic material.

Really learned a lot about the fundamentals of blockchain, being a software engineer looking into blockchain. It just got me up to speed with the underlying workflow of blockchain and more. loved it.

Learned a lot in this course. The only frustration was with completing the final programming assignment. The assignment wasn't difficult. What was difficult was the "Environment Set up."! Importing the Ethereum file into VM and executing it! Please specify the browser type (e.g. firefox, not Chrome) and VM version in the BODY of the programming assignment, not in the FAQs! This will eliminate 90% of the frustration and will speed up completion of the final assignment.

Didn't really enjoy the course. There is a lot of assigned reading. The actual content is very light.
