About the Course

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!

A very helpful course filled with practical knowledge on the way to become a successful blockchain developer, moreover when the open source material on this domain is abysmal.

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

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.

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

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

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 videos were very informative and I learned a lot. However the Course Material for the hands-on work in Week 2 and Week 3 is very outdated and it was a real struggle to deal with the version incompatibilities. I can imagine this being even more frustrating for someone to deal with, if they do not already have experience in Linux, CLI and general understanding of dealing with Version incompatibilities. A lot of research had to be done on my own and it also cost a lot of nerves to get the hands on running. Apart from that, the course was well structured and informative.

The Dapp course is well-structured and the videos are of good quality. However, some resources are either not available or outdated, which can be a hindrance to learners. Additionally, the course seems to be based on outdated versions of Solidity and Truffle, which can lead to confusion and difficulty in implementing the concepts learned. Overall, the course is informative and well-presented, but it could benefit from updating the resources and providing more up-to-date versions of the required tools.

This course is so outdated that it is almost impossible to get the tools the instructor uses to work correctly. I have spent far more time trying to fix things that don't work they way they used to when the course was recorded than learning about the material. It is a waste of my time and money.

Worst course on Coursera. Even the helping code has errors.

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
