The Role of Oracles in Blockchain Technology
Oracles are essential components of blockchain networks that connect smart contracts to real-world data, enabling them to interact with external systems like APIs and off-chain data sources. In this article, we'll explain how oracles work, their role in decentralized applications (dApps), and how they are used to trigger smart contracts based on real-world events. We'll also explore some popular oracle networks and their impact on the blockchain ecosystem, as well as the security challenges involved in using oracles.
