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.

Spent many frustrating hours troubleshooting due to outdated versions of referenced software. Badly in need of updating.

This course has many missing points not clearly specified flow. Still one can learn through own research.

The software behind Ethereum is immature. Should not be even allowed in beta release.

Almost all of this course is out of date and deprecated. The discussion forums are full of students begging for help and trying to come up with work-arounds for the old code. I decided to not finish the specialization at this point, which was disappointing, since I enjoyed the first two courses in the specialization.

Completely inadequate explanation as to how to set up the environment, truffle etc. Lectures far too short. Completely confusing resource materials. Nothing works. Flying blind.

The course's demo video on Metamask extension is outdated. No instructors or TAs came to the discussion forums to help on the outdated problem with Metamask's chain ID.

Many issues with the provided code/Truffle set up. This needs to be updated. Good references to external websites though.
