What is a DApp, A decentralized application (dApp) is a software application built on a blockchain or decentralized network, allowing users to interact with smart contracts and distributed ledgers. Unlike traditional apps, dApps operate without a central authority, making them transparent and resistant to censorship. They are powered by blockchain's decentralization and are typically open-source, providing users with more control over their data. dApps can be used across various industries, including finance (DeFi), gaming, and supply chain management, offering a decentralized alternative to centralized services.
