What is a Decentralized Application (dApp)?

A decentralized application, or dApp, is an app that runs on a blockchain or decentralized network, using smart contracts instead of relying only on a central company-controlled server.

Decentralized Application (dApp) Explained

A dApp is an app that uses blockchain technology behind the scenes.

A normal app usually depends on one company’s servers to store data, process actions, and control access.

A dApp uses smart contracts and blockchain records for some of those actions. This can let users connect with a wallet, own digital assets, or interact without a central middleman.

For example, a decentralized exchange is a dApp because users can trade tokens through smart contracts instead of a company holding their funds.
