What Is Chainlink in Simple Terms?

Chainlink is a system that helps blockchains get information from outside the blockchain world.
Blockchains are very secure, but they cannot naturally access real-world data like stock prices, weather, or sports results.
Chainlink solves this problem by acting as a bridge between blockchains and external data sources.
This allows smart contracts to use real-world information to function properly.
For example, a smart contract might need the price of Bitcoin or the result of a sports match. Chainlink helps provide that data securely.
It is decentralized, meaning no single source controls the information.
In simple terms, Chainlink is:
A bridge between blockchains and real-world data
A system that feeds external information into smart contracts
A key part of making blockchain applications more useful
