Smart contracts are self-executing agreements coded on blockchain networks like Ethereum or Binance Smart Chain. However, their functionality is limited without reliable external data inputs—a problem known as the "oracle problem." Oracles serve as trusted entities that feed real-world information into these contracts.

Chainlink’s decentralized approach involves multiple independent nodes (oracles) providing data to prevent single points of failure or manipulation. These nodes are incentivized through cryptographic security measures and economic rewards to ensure accuracy and integrity. This decentralization enhances trustworthiness compared to centralized or single-source solutions.
