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.
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.
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.

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.

The testing part was not clear as the cases defined in the assignment and the hints provided doesn't sound familiar to me. Overall the course was great!
This course is for anyone interested in designing and developing Dapps.
Are there any prerequisites?
Mastery of the content of the first course (Blockchain Basics) and second course (Smart Contracts) of this specialization is a prerequisite. Knowledge of at least one modern, high-level programming language is required. Some knowledge of command line interface and JavaScript programming is also necessary.
Are there any hardware requirements?
A laptop or a desktop of this specification: 64 bit machine with minimum 4Gb ram, 10Gb free space and Windows 7 or above , or ubuntu 16.04 or Mac os x 10.0+.
When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
