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.

Decentralized Applications (Dapps)
We will explore the notion of the blockchain server as the foundation for a Decentralized Application. We will demonstrate how to install the blockchain server and establish a peer-to-peer network of nodes. It is a common practice to develop and test a Dapp on a local test network before deploying it on a public network.

Truffle Development
We'll explore the user-friendly environment that Truffle provides for developing and testing a Dapp. We'll explore further the truffle commands such as: develop, init, compile, migrate, test - all with truffle in front of them and with any parameters. This module will illustrate the steps needed in developing and testing a complete Dapp.

TOP REVIEWS FROM DECENTRALIZED APPLICATIONS (DAPPS)
by SRDec 28, 2019
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.
by GMJan 11, 2019
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Beautifully designed content with just one concern, data is to outdated makes a lot of errors denying some good hands over the real handson else everything is fine.
About the Blockchain Specialization
This specialization introduces blockchain, a revolutionary technology that enables peer-to-peer transfer of digital assets without any intermediaries, and is predicted to be just as impactful as the Internet. More specifically, it prepares learners to program on the Ethereum blockchain. The four courses provide learners with (i) an understanding and working knowledge of foundational blockchain concepts, (ii) a skill set for designing and implementing smart contracts, (iii) methods for developing decentralized applications on the blockchain, and (iv) information about the ongoing specific industry-wide blockchain frameworks.
