What is a DApp, A dApp, or decentralized application, is software that runs on a blockchain instead of centralized servers. It uses smart contracts to perform automated functions without relying on a central authority. DApps can range from games and social media platforms to financial services and supply chain tools. Built typically on Ethereum or similar platforms, dApps offer transparency, censorship resistance, and user control. Users interact with dApps via blockchain wallets. As the foundation of Web3, dApps are reshaping how users engage with digital services by emphasizing privacy, ownership, and decentralization.
