How Is Data Integrity Verified by a Smart Contract Using an Oracle?

The smart contract is coded to expect data from a specific, trusted oracle contract address. Verification mechanisms can include checking for multiple signatures from a DON, verifying a cryptographic proof of the data's source, or ensuring the data falls within a certain range.

This process ensures the data is authentic before triggering execution.
