What is Chainlink (LINK)?

Chainlink is a platform of decentralized oracle networks that provides smart contracts with services including external data and cross-chain communication. LINK is its token, used in service payments and certain security mechanisms. The network and the token are related, but they are not interchangeable concepts.

Is Chainlink the same thing as LINK?

The network supplies infrastructure that delivers the information or messages an application needs. LINK has a role in its economic operation. Owning LINK does not make someone a company shareholder or automatically entitle them to profits. Adoption and token price need not rise at the same rate.

Receiving a price input and sending a message to another chain are different services. Fees, supported networks and security conditions depend on the product being used.

Example: a price feed for a lending protocol

Suppose a user deposits 2 ETH as collateral in a hypothetical lending application. At a feed price of $2,000 per ETH, the contract values the collateral at $4,000. If the reported price falls to $1,500, the same 2 ETH is worth $3,000. Chainlink can supply the price input; the lending application’s own rules determine borrowing limits and liquidation conditions.

The prices are illustrative, not current quotes. A delayed update or a misconfigured application can affect the calculation. Using an oracle does not remove every risk in the lending protocol.
