Decentralized finance (DeFi) refers to the infrastructure, processes, and technology used to democratize economic transactions.
It works on dApps (decentralized applications) to manage transactions and run blockchains.
Transactions are stored on a secure, immutable blockchain. Instead of fiat currency, transactions are made in cryptocurrencies.
It is believed to be the future of finance where transactions are executed in real-time without third parties using blockchain technology powered by smart contracts.
Common types of DeFi applications include decentralized exchanges, stablecoins, lending platforms, wrapped bitcoins, and prediction markets.
DeFi adoption picked up momentum in mid-2020, reaching nearly $100 billion in TVL by the end of 2021.
The DeFi market has since declined due to hacks, liquidity crunches and regulatory stress.
