What is a DApp, A DApp (Decentralized Application) is an application that operates on a blockchain or peer-to-peer network rather than a centralized server. DApps leverage smart contracts to ensure transparent, secure, and trustless interactions. They are open-source, meaning anyone can participate in their development, and are resistant to censorship since they do not rely on a single point of control. Popular DApps include decentralized finance platforms, games, and marketplaces, and they typically use Ethereum, Binance Smart Chain, or other blockchain platforms for their underlying infrastructure.
