Cryptocurrency's promise is to make money and payments all around accessible to anyone, regardless of where they are on the planet. The decentralized finance (DeFi) or open finance development makes that promise a stride further.

Imagine a global, open option in contrast to each financial service you use today - investment funds, loans, trading, insurance, and more are accessible to anybody in the world with a cell phone and internet connection. This is presently conceivable on smart contract blockchains like Ethereum. Smart contracts are programs running on the blockchain that can execute consequently when certain conditions are met. 

These smart contracts empower developers to work undeniably with more modern functionality than essentially sending and accepting cryptocurrency. These projects are what we currently call "decentralized apps" or "dapps". 

You can think about a dapp as an app that is based on decentralized innovation, instead of being built and constrained by a solitary, unified substance or organization. Become accustomed to this word, dapp, you'll be seeing it a ton from now into the foreseeable future. 

While a portion of these concepts may sound cutting edge, automated loans negotiated straightforwardly between two strangers in different parts of the world, without a bank in the center a large number of these dapps are now live today. 

There are DeFi dapps that permit you to make stable coins (digital currency whose worth is fixed to the US dollar), loan out money and earn interest on your crypto, apply for a loan, trade one asset for another, go long or short assets, and carry out computerized, advanced investment strategies.
