In the blockchain ecosystem, data is power — but blockchains alone can’t access real-world data. That’s where Chainlink (LINK) steps in, serving as the bridge between on-chain smart contracts and off-chain information . With its revolutionary oracle technology , Chainlink enables smart contracts to securely interact with real-world data like prices, payments, weather, and more — making blockchain applications practical, reliable, and truly decentralized. 💠 What Is Chainlink? Chainlink is a decentralized oracle network launched in 2017 by Sergey Nazarov and Steve Ellis . Its main goal is to solve one of blockchain’s biggest limitations — the inability to access external (off-chain) data directly. Smart contracts, by design, can’t reach beyond their own blockchain. Chainlink provides a secure data pipeline that connects these contracts with real-world information, such as: Market prices for DeFi protocols Weather reports for insurance contracts IoT sensor dat...
