This third course of the Blockchain specialization prepares you to design and develop end-to-end decentralized applications (Dapps) – which provide anyone with access to the blockchain’s features and services. You will use Truffle IDE, smart contracts, a simple web client and a MetaMask client. You will learn about the architecture of a Dapp: the front-end client interface, backed by the blockchain and smart contracts. The course covers the basic design of a Dapp, Truffle development process and commands (init, develop, test and migrate), test-driven development of Dapp, Dapp application models and emerging standards that are essential for predictable Dapp behavior. Main concepts are delivered through videos, demos and hands-on exercises.

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!
NC
THis course provide some level of workshop/practice which help me clearly understand the building block of a Dapp. Very useful.
HA
Although course needs an upgrade in videos because it is very old and since than alot has changed but all the concepts are explained very well
PP
course is good, but the code use in this course is quite old now. I think instructor should replace these code and demo
LT
Excellent course that provides an in-depth and hands-on experience for the development of Dapps with Truffle Framework
ON
A very recommend course to understand the enviroment across decentralized apps and the tools to develop this kind of solutions !!
VC
Well designed course for Beginners to start with DApp development on Ethereum with High-level Language called Solidity.
FG
Javascript interactions were not described at all, but the final test is not that complex, so i guess that is ok
NV
Excellent overview of D-APPS and Smart contract testing. However, the project VM experience could be vastly improved. The VM is very slow to load and execute commands.
NA
Overall very nice! Some of the coding examples in the course are out of date, specially the example with MetaMask
RS
This was a wonderful course. What I wished I knew before taking it was javascript. The programming which required knowledge of it was what made this course difficult for me.

I really enjoyed the course. I like ma'am bina ramamurthy teaching style, to give the student a clear understanding of each topic.Thanks very much for this course.

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
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.
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.
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
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.
The course is awesome, but I would like that it is updated with current tools since it is a little bit dated.
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.
