Precio, gráfico y análisis de ChainLink (LINK)

A blockchain cannot see outside itself. A lending contract that needs to know the price of ether has no way to look it up, and that gap — the oracle problem — is what Chainlink was built to close. It is infrastructure rather than an application, which makes it less visible than it is important.

How it works

Independent node operators retrieve data from multiple sources, and their answers are aggregated on-chain into a single reported value, with outliers discarded. Operators are paid in LINK and are expected to maintain accuracy to keep earning. The design assumes no single node is trustworthy, which is the whole point: a price feed sourced from one place is a single point of failure, and several protocols have been drained precisely because theirs was.

Supply

LINK has a fixed maximum of one billion tokens, created at launch rather than mined. A substantial portion was retained by the project to fund development and pay network incentives, and those holdings have been released gradually over the years, so circulating supply has risen steadily. Check the circulating and maximum figures on this page together — the gap between them is the part that matters.

What to watch

The useful measure is adoption: how much value across DeFi depends on Chainlink feeds, since that is what the network secures. Also watch the expansion beyond price feeds into verifiable randomness, cross-chain messaging and proof-of-reserve attestations, and watch whether those services generate fees that flow to node operators rather than being subsidised.

Where it is used

Chainlink price feeds underpin a large share of lending markets, derivatives protocols and stablecoins. When a protocol liquidates a position, the price that triggered it very often came from here.

Two risks deserve naming. The first is the token’s relationship to the network: heavy use of the oracles does not automatically translate into demand for LINK, and the link between the two is a genuine argument rather than a settled fact. The second is systemic — because so much of DeFi relies on the same feeds, an oracle failure would not be contained to one protocol. That concentration is the cost of having solved the problem well.
