What is Chainlink?
Chainlink (LINK) is a decentralised oracle network that feeds outside data, such as prices, into smart contracts. Smart contracts cannot reach the wider internet on their own, so they rely on services like this.
How it works
LINK is the token used to pay for and help secure these data services. Reliable data is important for many DeFi applications, which use it to settle contracts fairly.
