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.

Setup and structure of the course and the content is really excellent and helped me understanding how to build Dapps on the back of smart contacts.

HOWEVER: following the course in order to build the "ballot" Dapp with the truffle ide etc in week 2 has been an extremely frustrating part. And i have been through a lot of pain and wasted hours with outdated software versions, grader issues etc in other Coursera courses earlier! A pitty really! Fair enough - it wasn't made part of the final project. Still: It is the reason for a 4 stars rating instead of 5!

Good introduction to Dapps. You test your smart contract and then build a webapp. I don't give five stars because it is a bit old. I read some other articles and blogs and nowadays things are a bit more easier. Also programming tasks have some issues as they are not compatible with some technologies. Nice introduction to start with, but have to search around for updated work

The course content was good and all but the end project was very bad. First of all, ethereum.ova was shipped with truffle 4.0.4 or whatever, which was not working correctly. I had many issues with it other then truffle init not working. Secondly in Part 2 was to write test.js while we were not taught about it in enough detail

Is a very good course for learning new tools and the workflow of how to develop DApss end to end. Needs to be updated to include newer versions of Truffle, Solidity, etc. And the course resources should reflect this updates to make it easier and more compatible when it comes to the course projects.

The course gives a great foundation to build a blockchain based application. The content some how seems to be old for there are many more technologies and methodologies coming up now. some items like Oraclize are depricated. Nevertheless, it is a great course.

Good information taught throughout the course and the only downside was that some technological compatibilities were not kept up to date, which can sometimes take away from the current scope of the module. Learned a lot with figuring some of it out though!

this course is far better then any other course that i can find in the internet in 2020 but this course need to be updated with time . because solidity, truffle and web3 is constantly updating . so old language/framework/library are becoming deprecated .

It's a very good course, not giving 5 stars only because a couple of questions were really context-dependent and it's hard to answer them correctly without searching through the precise wording of the lessons.

Very insightful if you have a basic understanding of the blockchain technology. Totally recommend for blockchain newbies looking to up their game. Thanks coursera and keep recommending badass courses. CHEERS!

Great course especially if you follow the readings religiously. Only thing is the exercise and snippet are outdated, but that helps in exploring so you don't do copy paste :)

It has a good content and it's quite challenging to create the Dapp, I think it's a good introduction for anyone to have an idea about how to build a Dapp from the scracth

Beautifully designed content with just one concern, data is to outdated makes a lot of errors denying some good hands over the real handson else everything is fine.
