Chainlink is a decentralized oracle network that enables blockchain-based smart contracts to access real-world data stored off-chain. To achieve this, Chainlink rewards data providers called oracles. These providers supply accurate and useful data in exchange for Chainlink's native ERC-20 token, LINK.
Key Features of Chainlink
- Composed of nearly 1,000 independent decentralized oracle networks.
- Supports 12 blockchain networks, including Arbitrum, Avalanche, Ethereum, and Polygon.
- Offers services like Verifiable Random Function (VRF), Keepers, Proof of Reserves, and Cross-Chain Interoperability Protocol (CCIP).
- Off-Chain Reporting (OCR) reduces operational costs by 90% while providing 10x more data to smart contracts.
