Frequently asked questions
What is a blockchain 'oracle'?
An oracle is a service that brings external, real-world data — such as asset prices — onto a blockchain so smart contracts can use it. Blockchains can't natively access outside data, so oracles like Chainlink bridge that gap.
What is LINK used for?
LINK is used to pay Chainlink node operators for retrieving and delivering data to smart contracts, and can also be staked in some Chainlink programs to help secure the network.
Is there a maximum supply of LINK?
Yes. Chainlink's total supply is capped at 1 billion LINK tokens.
