The Link token

Quick take - Link token

All LINK tokens (1B total) were issued in September 2017 at inception, which is to say that there is a finite supply.

Utility

The LINK token is used to pay Chainlink node operators for their oracle services (on-chain data aggregation and submission & off-chain computation services). In addition, once Chainlink staking goes live, Chainlink node operators will be able to deposit a specific amount of LINK as collateral in order to be elegible to service specific requests. This was first outlined in the original whitepaper.
