DApp

Decentralized Application — an application running on a blockchain network.

A DApp (Decentralized Application) is a software application that runs on a distributed network (blockchain) rather than centralized servers. DApps combine smart contracts on the backend with a traditional user interface on the frontend.

Characteristics

Open Source: Most DApps have publicly verifiable code.

Decentralized: Data and records are stored on a blockchain.

Incentivized: Validators are rewarded with cryptographic tokens.

Protocol-Based: The community agrees on a consensus mechanism.

Categories

DApps span many categories including DeFi (Uniswap, Aave), gaming (Axie Infinity), social media (Lens Protocol), NFT marketplaces (OpenSea), and identity solutions (ENS).
