Blockchain-built dApps, protocols, smart contracts, and digital assets are the key elements of decentralized finance. The Ethereum framework is the primary choice for the DeFi application considering the adaptability and the level of development, but that doesn't imply it's the only blockchain forum.

DeFi is a development in the cryptocurrency industry, aimed at recreating conventional banking services without centralized technologies. Bitcoin itself is a prototypical illustration of DeFi; the majority of other cryptocurrencies depend on central organizers or issuers. DeFi is implemented via dApps, typically installed on either a blockchain such as Ethereum or a tangle such as IOTA.

Decentralization suggests that there is no single point of failure since similar records are kept across a peer-to-peer network throughout a plethora of computers. Since it's unregulated, it is also available to all regardless of their income or where they stay. And, while a payment processing firm or a bank can close an unseemly customer's account, blockchains are immune to surveillance.
