The course in unmaintained. Lecture said the software updates too fast, so they hang with an old version. However, it is incompatible with its external resources. Students spend time finding fixes, instead of learning.

Presentation by instructor is not good. Assignment is confusing

Very basic, it was more informative than practical

The course is very good as foundations concepts.

It is important to update some elements, as some course materials were developed a few years ago.

The whole process to develop a Dapps is very complicated and it involves may parts beyond Smart Contract coding. In this 4 weeks course, it will be too short to address all the components.

The course do a good job to showcase the use of Truffle and Chrome Plug-in (metamask) for testing Smart Contract before deployment.

Yet, SW compatibility (Metamask) and setting on Truffle configuration file will cause much trouble to students. So, I suggest the course creator update the VM for the course and related materials to address these issues.

Instructor teaching process is too simple. I like this course. But syallbus is too short.

This was by far the most challenging course that I have taken so far in the blockchain specialization. One possible piece of constructive feedback is that since this course and the files are from some time ago (i.e., 3-5 years in some cases), and the software we are using updates frequently and sometimes the version used in the course is drastically different from what's out now, it helps to have tutorials on how to make adjustments. I had to do a lot of research on my own to get the correct version, as well as uninstall/reinstall multiple times to fix issues. I really like this course and format and just want to see it be as successful as possible.

The course gives a great overview, but I'm missing more details about

Frontend <-> Smart Contract interaction

Embedding of Libraries into a Smart Contract

Integration and/or usage of Layer 2 Solutions

Implementation of an Oracle

Design and Usage of Events in Frontend Applications

(Security) Design Patterns such as global singleton by a Fabric

The course structure is concise yet insightful in nature. It allows you to explore, experiment and learn through that process.

It is an interesting and good course.

The course gives detailed knowledge about smart contract best practices and the Dapps.

Well designed course for Beginners to start with DApp development on Ethereum with High-level Language called Solidity.

Этот курс дал всю основу для того, что бы можно было развивать свои навыки практически без ограничений.

Very nice course, I learned how to program in solidty and testing by writing JS code.

Great Course, let people have excellent learning about Blockchain and DApp.

It is all perfect. The only downside is that I am not that good with js :D

Great hands on intro to developing Dapps for Ethereum with Truffle.

Exccellent course, very motivating, well organized and structured.

The topics covered are extensive and address the core fundamentals of Ethereum Dapps. However there is a lot of versioning issues with nodejs, npm, solidity, metamask and truffle. A lot of changes in the software, syntax and versions has happened since the course has released. For instance, the use of Ganache UI. Also it would have been better if there were a section on debugging the various errors which happen in the installation process. Lastly, it would have been more prudent to include a front end development and linking section also. That being said the course does manage to cover dozens of topics and provide knowledgeable insight in Dapps and Ethereum. Well paced and brilliantly taught. 4 stars for that.

The code in the final is pretty poor quality. Good basic instruction though.

The 3rd course in this specialization continues building on the previous one. The programming assignment is intimidating at first glance, especially if you are not used in JavaScript style syntax and programming. As usual, with some effort someone is able to overcome all challenges. Again, in order to acquire a more in-depth look in these concepts, personal dedication and effort is required beyond the minimal time-commitment stated in the course's review

I had a good understanding of blockchain basics and working of etherum, i am one kind of person who always worked with one language, the integration of multiple languages always made me puzzled. This course helped me and guided through the whole process very smoothly. Now i understand the use of several platforms like truffle, metamask, blockchain server, solidity, smart contracts, test cases etc.. Thank mam..

I am enjoying thid course so much because the material and instructor provide clear instructions and information to make learning fun and easy. I am an older student and I am very anxious about learning. I am planning to take as many courses as possible to further my growth and development within the Block Chain Industry.

Great course, somewhat more challenging and involved than previous courses in this specialization.

Once you are done with the testing, you will feel very confident that you can write, debug and test Solidity smart contracts, no doubt!

Thank you for such great work and effort creating this course.

I always wish to find such a platform, where i can test my skills.

And i am surprise to know coursera has all the functionalities and courses i was looking for.

i really enjoyed synchronizing my knowledge with a professional certification.

it would have been nice if the instructor has included the instructions for truffle+ganache installation for local machine. Truffle works great on a native machine over vm! thanks!
