Chainlink is a decentralized oracle network.
Blockchains cannot access real-world data by themselves.
Chainlink solves this problem by securely bringing off-chain data (real world) on-chain.
🌍 What kind of data does Chainlink provide?
💲 Crypto prices (BTC, ETH, stocks, forex)
🏦 Interest rates
🌦 Weather data
⚽ Sports results
🧾 Proof of reserves
🏠 Real World Assets (RWA)
⛓ Cross-chain communication
Without Chainlink, DeFi cannot function safely.
🧠 Why Chainlink is extremely important
Most major crypto systems depend on it:
Aave
Compound
Lido
Uniswap
Swift (banking)
DTCC (traditional finance)
👉 Over $20+ trillion in transaction value secured.
