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.

I would have given this course 1/5 stars because using VirtualBox gave me cancer and MetaMask didn't even work properly, but the concepts covered were really interesting so it's a pass.

Truffle environment wasnt as easy as Remix to setup. Spent many days trying to use higher version of Truffle since Truffle init wasnt working at Truffle 4.0.4 version.

Course is god but it should be upgraded by now. Its almost 20months old course which used soidity 0.4.17 and current version of solidity is 0.6.0+

So kindly upgrade.

Good course content, but it needs an update because current solidity and truffle versions generate a lot of problems with the course documents and templates

Some of the videos were lower quality than the past courses and a few topics felt extremely rushed. I really enjoyed the courses before this one.

Sessions were good. Assignments were difficult considering that there was a version change. Did not get support on the questions asked.

Core concepts are not explained well and it really focuses on introduction of different topics they do not explain them in detail.

Too much information poorly explained. Easy to overlook but impossible to really develop a real programming knowledge.

Not easy to comprehend and explain in a very vague manner specifically dapps development and deployment.

Final assignment Somehow too difficult for learners without prior knowledge in programming.

A​utograder can be a nightmare. Course content is seriously dated at this point.

This course was probably great when written but is suffering from a clear lack of maintenance. The virtual machine setup is seriously out of date and even the solidity version it runs is no longer supported. I spent hours just getting the environment set up correctly and you needed to fix broken examples and sample code. I would say this added weeks to the completion time and was frustrating with little support and few answers from the teacher or staff. I would suggest a total refresh of the course.

Perhaps the worst taught course I have taken on Coursera. Presentation of the material could have been much better. The teacher just reads off a script and mumbles during demos.

My biggest takeaway is the additional material. I learnt a lot more from them than by watching the video lectures.

a good course content, but the verification of programming assignment is terrible. I spend half of the day constantly rewriting the same! content in file to get it passed. As I see, it was raised a number of times on the forum.

Like the other courses in this specialisation, the information is superficial and mostly consists of pointers to more useful resources. The videos are boring, and the final project is badly set up.

The process of developing a DAPP was superficially explained. You gain almost no hands-on experience at the end of this course.
