Chainlink provides oracle and related middleware (price feeds, CCIP, reserve proofs) consumed by DeFi and institutional integrations. LINK is used in node operator staking and fee economics for those services. Price is not a simple equity claim on feed revenue; demand ties to product adoption and staking parameters.
Research use: map protocol dependence on Chainlink feeds, fee/staking design changes, and competitive oracle stacks. Oracle failure modes are first-order for DeFi risk, independent of LINK spot price.
