Oracles
Chainlink
Chainlink is the leading oracle network and one of the most important infrastructure layers in crypto because it helps smart contracts access external data. Beginners should learn Chainlink early because many DeFi, stablecoin, and tokenized-asset systems depend on reliable offchain information.

Why It Matters
Chainlink addresses a basic limitation of blockchains: they cannot natively verify external data on their own. Chainlink remains central because so much of DeFi, tokenization, and automated onchain execution depends on trustworthy data entering the system from outside the chain.
