# 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 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
