Chainlink serves as a critical decentralized oracle network in Web3, bridging smart contracts with real-world data, APIs, and off-chain systems. It ensures DApps can access reliable, tamper-proof data feeds (e.g., price feeds, weather data) to execute trustless logic. By enabling secure data integration, Chainlink empowers DApps across DeFi, gaming, and supply chain, enhancing their functionality and scalability. Its potential lies in its ability to expand data accessibility, fostering more complex and interoperable DApps.
