What is LINK token used for?
LINK is the native token of Chainlink, a decentralized network that connects blockchain smart contracts with real-world data. Think of it as a bridge between cryptocurrency and external information. LINK token holders can stake their coins to become node operators—validators who provide reliable data to blockchain applications. In return, they earn rewards. LINK is also used to pay for data services on the network. For example, if a DeFi lending protocol needs current price information, they pay node operators in LINK tokens to fetch and verify that data accurately. With over 1,000 nodes operating globally, Chainlink has become essential infrastructure for smart contracts requiring external data verification, making LINK valuable within the cryptocurrency ecosystem.
