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. Continuing education units (CEUs) and professional development hours (PDHs) are available through the UB Center for Industrial Effectiveness (UB TCIE) for learners who earn a course certificate....

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!

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.

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.
