Chainlink serves as a decentralized oracle network in Web3, bridging smart contracts with real-world data, APIs, and off-chain systems. It supports DApps by providing secure, reliable data feeds (e.g., price data for DeFi), off-chain computation (e.g., Automation, VRF), and cross-chain interoperability (e.g., CCIP). With over $8 trillion secured by mid-2024, Chainlink’s infrastructure enhances DApp functionality, enabling complex use cases like decentralized finance, gaming, and NFTs. Its scalability and trust-minimized services position it as a foundational layer, potentially driving widespread DApp adoption and innovation across the Web3 ecosystem.
