What is the role of an oracle in blockchain?
A blockchain oracle provides real-world data to smart contracts.
Types of Oracles:
Inbound: Fetches external data (e.g., price feeds).
Outbound: Sends blockchain data to external systems.
Decentralized: Uses multiple data sources to prevent manipulation.
Popular Oracles:
Chainlink
Band Protocol
Oracles enable DeFi applications but must be resistant to tampering.
