A decentralized application (DApp) is a type of software application that may run independently, generally using smart contracts, on a decentralized computer, blockchain, or other distributed ledger system. DApps offer some kind of function or benefit to their customers, but they are not owned by any single business.
DApps have been popularised by distributed ledger technologies (DLT) such as the Ethereum or Cardano blockchains, leading to significant advancements in the use of these functionalities within the decentralized finance (DeFi) area.
DApps are classified into a variety of areas, including exchanges, games, finance, gambling, development, storage, high-risk, wallet, governance, property, identity, media, social, security, energy, insurance, and health.
