# Oracle Functionality

Oracles play a pivotal role in calculating the POG score by processing and aggregating user-specific data. The workflow is outlined as follows:

* Data Fetching: The Docker image pulls user data from verified APIs and internal metrics.
* POG Computation: Using a standardised algorithm, the Oracle processes this data to compute a user's POG score based on factors such as user performance, consistency, and engagement.
* Data Integrity: Before submitting results, Oracles sign the calculated POG scores using cryptographic keys unique to each Oracle. This ensures that data integrity is maintained and any tampering is easily identifiable.
* Score Submission: Oracles submit the signed PoG scores to the Aptos blockchain for validation.
