课程概述

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....

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.

THis course provide some level of workshop/practice which help me clearly understand the building block of a Dapp. Very useful.

The course material was great and covered very important information; however, I strongly feel that the projects for this class need to be updated considering the amount of work arounds I needed to use in order to keep up. Specifically it was difficult using metaMask with-in VirtualBox due to changes in UI, and this affected the success in deployment of our sample dapp.

The programming environment was not working, the software version was old, I struggled a lot to make test cases work due to environment inconsistencies. For the majority of topics we have just scratched the surface. The most interesting Module so far, but also the least valuable in terms of usability and level of information I gained.

The course is fine but the practice exam give me a lot of problems to submit my test script. No matter what I try, the grader won't accepted. It took me almost 3 hours to figure it out what to do, despite the info already in the forum. I think the grader should be a little "smarter"

This turn out to be a very bad experience for me.

Nice overview of Blockchain and Ethereum and practice creating decentralized apps from start to finish. Given the fast pace of Blockchain technology, many of the programs and libraries are outdated. I spent a lot of time re-coding for the latest libraries. It would be helpful if a moderator updated the materials.

Even though the course contains a lot of useful information, most of the time you will struggle to make the out-to-date code work. It is a pity that authors put zero effort into maintaining the code to correspond to modern IDEs and standards so learners could be deep in studying but not debugging.

Course covers all the basics about Dapps and truffle. But the main concern is the some of the codes are outdated. Links are broken and there are changes in metamask which makes it difficult to follow especially if used in virtualbox. The course needs to be updated.

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.

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.
