Chainlink is a decentralised oracle network that supplies blockchains with external data, price feeds, proof-of-reserve information and cross-chain messaging. LINK is used in the network's economics around oracle services, staking and node operator incentives.
The Chainlink price in AUD is commonly linked to DeFi adoption, institutional tokenisation pilots, oracle revenue and demand for secure off-chain data. LINK is often researched as infrastructure exposure rather than a pure layer 1 or payments asset.
