Overview

Chainlink is a decentralized oracle network. It supplies off-chain data, price feeds, and cross-chain messaging (CCIP) to smart contracts.

Highlights

  • It is widely used for price data in DeFi derivatives, lending, and stablecoin systems. Market share changes over time and is not a fixed guarantee.
  • CCIP is its cross-chain protocol, used by some projects and institutions to move messages and tokens between chains.
  • It also offers verifiable randomness (VRF) and proof-of-reserve data feeds.

Token model

The cap is 1 billion LINK. The token pays node operators and can be used as stake for oracle services.

FAQ

Why do blockchains need oracles?

A contract cannot read exchange rates, weather, or equity prices by itself. An oracle network brings signed external data on chain after its own consensus checks.
