Participants in these programs are required to stake a certain amount of $IFX tokens by purchasing a node license. The number of $IFX tokens needed varies depending on the type of node and the timing of the license purchase. Node sale programs will be organized into tiers based on the order of the sale. As a general rule, the earlier the license is purchased (the lower the tier), the cheaper the price. Licenses purchased before the TGE are referred to as *whitelisted* and participants who acquire whitelisted licenses will receive more benefits and discounts compared to those who purchase after the TGE. --- # 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.inferix.io/inferix-whitepaper/economic-model/node-sale-and-penalty-pool/node-sales.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.
