How does Chainlink work?
When Chainlink was launched in 2017, the original white paper envisioned the project as a centralized oracle system for verifying incoming information. The Chainlink 2.0 white paper in April 2021, however, highlighted a transition from a centralized oracle system to a decentralized oracle network.
By design, Chainlink is blockchain agnostic, meaning it doesn’t operate its own blockchain or work solely within another blockchain. Instead, the token protocol runs on many different blockchains simultaneously and has incentives for its participants to provide and use Chainlink data within their blockchain smart contracts. Chainlink’s oracle network can be used for everything from the weather to presidential election results.
