Lesson Overview

1.17 – Oracles and Real-World Data in Blockchain: Oracles act as bridges between blockchains and the outside world. They feed real-world data—like weather, prices, or election results—into smart contracts that depend on external facts. Without oracles, blockchain applications would be limited to internal information only. Reliable oracles ensure contracts trigger accurately and securely. Projects like Chainlink specialize in providing decentralized oracle networks to prevent tampering. Oracles expand blockchain’s usefulness by connecting it to global data streams, enabling insurance, finance, and logistics automation that responds to real-world events.
