Chainlink plays a pivotal role in Web3 as a decentralized oracle network, bridging smart contracts with real-world data and off-chain computation. It supports DApps by providing secure, reliable access to external data (e.g., price feeds), enabling automation (Chainlink Automation), verifiable randomness (VRF), and cross-chain interoperability (CCIP). This enhances DApp functionality across DeFi, gaming, and NFTs, unlocking complex use cases like dynamic asset pricing and trustless transactions. With its scalable, tamper-resistant infrastructure, Chainlink empowers developers to build feature-rich, interoperable applications, potentially driving Web3 adoption by connecting blockchains to traditional systems seamlessly.
