[Blah-Chain : Talk11. dApp (Decentralized application)]

Last time we have talked that Ethereum is a computing platform or “operating system” based on Blockchain Technology.

Smart contracts and dApp are mentioned as the main features of the Ethereum. We have already talked about smart contracts then let’s talk about what a dApp is today.

As you can guess from its name, it means applications.

It’s short of Decentralized Application, which means applications based on the decentralized blockchain technology.

It’s like other applications you’ve installed on your smartphone but the difference is that a dApp is decentralized.

Since blockchain is decentralized, applications based on the blockchain technology can be called “dApp”.

Assume that you want to enter on a website. If you log in,

the website will bring information from their server.

But when it comes to the dApp, they use blockchain instead of the server. Since all information is decentralized and distributed, dApp is more secure and transparent.

A dApp is an application which can be implemented on Ethereum blockchain. If Ethereum is a smartphone, dApp is an application which you can install on your smartphone. Anyone can program certain conditions and command so it can be implemented on Ethereum.
