🧠 Chainlink explains: Push vs Pull — how oracles work and why it's important

Oracles are a bridge between the blockchain and the outside world. Without them, smart contracts would be "blind".

🔁 Push model (Scheduled Publication)

Data is "pushed" into the blockchain at a specified frequency:

– ⏱ Updates occur on time or by trigger (for example, a significant price change);

– 📊 Used in Aave, Spark, Morpho — where data stability and availability are important;

– 🔌 Implemented through Chainlink Data Feeds.

✅ Ideal for lending and interest protocols where a guaranteed source of data without delays is needed.

⚡️ Pull model (Data on demand)

The smart contract "pulls" data itself when needed:

– 📍 Works in real-time — especially important for perpetual exchanges, DeFi DEX, HFT;

– 🔄 Current data is gathered in fractions of a second when the contract is called;

– 💻 Used in GMX, Jupiter, Kamino via Chainlink Data Streams.

📌 Conclusion:

Oracles are no longer just price providers. They are the architectural foundation of DeFi. By supporting both models, Chainlink remains not just an infrastructure — but a cornerstone for the future of Web3.$LINK
