Crypto 101 📚 Two Oracle Models
Pull-based oracles store signed prices off-chain. When making a transaction, the app submits the price along with it, and the on-chain contract uses it only after verifying the signature.
Push-based oracles actively push prices on-chain according to predefined rules. Contracts can read the latest on-chain price at any time.
The most expensive thing in crypto isn’t fees—it’s the cost of not understanding the rules.
$PYTH and $LINK are the tokens of the Pyth and Chainlink oracle networks, respectively.
