關於此課程：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.

此課程適用人群：This course is for anyone interested in designing and developing Dapps. Mastery of the content of the first course (Blockchain Basics) and second course (Smart Contracts) of this specialization is a prerequisite. Some knowledge of command line interface and JavaScript programming is also necessary.

授課大綱

第 1 週

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.
