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.

Principales reseñas sobre DECENTRALIZED APPLICATIONS (DAPPS)
por SR28 de dic. de 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!
por RS10 de sep. de 2020
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.
por GM11 de ene. de 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
por MV3 de jul. de 2020
Beautifully designed content with just one concern, data is to outdated makes a lot of errors denying some good hands over the real handson else everything is fine.
Acerca de Programa especializado: Cadena de bloques
