# PRL Token Utility and Purpose

PRL is the medium of exchange within the Perle data marketplace. Enterprise clients use PRL to pay for data annotation services, model fine-tuning, and quality assurance workflows through perle.ai. Contributors earn PRL for completed and verified work on perle.xyz.

**This creates a direct economic loop:**

* Enterprises purchase PRL to access Perle's expert annotation services
* Contributors earn PRL for verified, high-quality data work

### Data Provenance and Audit Trail

Every PRL transaction within the annotation pipeline serves as a verifiable link in the data provenance chain. When an enterprise client receives labeled data, the PRL transaction history provides a cryptographic audit trail showing:

* Which contributor performed the annotation
* Their on-chain reputation score at the time of completion
* The quality review steps were completed
* The timestamp and verification of each step
