This conversion occurs within the DataHub, where contributors claim their **$PUBLIC** tokens by burning (consuming) the corresponding number of points. #### **Conversion Formula** The number of tokens a contributor receives per point is calculated based on: * **X**: Total campaign revenue (in USD) * **W**: Total points distributed for the campaign * **P**: **$PUBLIC** token price (in USD) at the end of the campaign * **T**: Amount of **$PUBLIC** tokens per point The formula is:
Or simply: > **Each point = (Campaign Revenue ÷ Token Price) ÷ Total Points Issued** *** #### **Dynamic Exchange Rate** Because: * Campaign revenue (**X**) varies, * $PUBLIC token price (**P**) fluctuates with the market, * Total campaign points issued (**W**) differs by campaign, The point-to-token exchange rate is dynamic and changes over time. This mechanism ensures a fair, transparent, and performance-based reward system where contributors are compensated proportionally for both their efforts and the campaign’s real-world economic value.
