Spend or make a donation with the Fruits coin(s) in your Fruits Wallet. Smile coins will then be granted according to the content of your spending or donation. Donate the Smile coin that you are given within the dedicated donation platform. You will then be rewarded Seed Tokens (TFSTs) that can be used for different purposes. At first glance, it seems simple. However, this series of mechanisms leads to the realization of the unique functions implemented by the features of our PoC consensus algorithm. It is this simple functionality that makes it possible to create a new ecosystem that will change the future.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://whitepaper.fruitsblockchain.com/1.-basic-development-of-fsfp-fruits-social-finance-platform/1-1.-the-fruits-multi-layered-smart-contract.md?ask=<question>&goal=<endgoal>
```

`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.
