Technical principles | How do smart contracts get prices from outside the blockchain?
Chainlink uses a group of independent nodes to aggregate quotes from multiple sources, then writes them to the blockchain.
If an oracle reports an incorrect price, contracts that rely on it may settle incorrectly. That’s why diverse data sources and decentralized nodes are so important.
$LINK is the token of the decentralized oracle Chainlink. Current price: 9.975.
Be extra cautious when you come across projects claiming to offer stable, high returns.
