After a merchant plays music, SIG is minted and enters a 72-hour pending settlement pool. If no consumer-side conversion occurs within 72 hours, meaning there is no real user consumption, 100% of the SIG is burned. If conversion occurs, 80% is burned and 20% is released to the merchant. #### Design Purpose The purpose is to strictly anchor SIG supply to real demand and prevent “fake traffic mining”. ### Four-Layer Anti-Farming Verification for SIG * Playback devices must be registered on-chain, with one address per device. * A single song must be played for at least 30 seconds. * The same device can count the same song a maximum of 6 times within 24 hours. * Playback time must match the business hours of the geographic location registered for the device. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.miuro.ai/token-economy/usdsig-mechanism-explained.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
