# 30 Attribute generation और randomness verification

Gem NFT attributes random-like process से generate होते हैं, लेकिन यह process single source पर निर्भर नहीं होना चाहिए।

CryptoStone randomness design में निम्न elements शामिल हो सकते हैं:

* user-provided entropy
* recent multi-block entropy
* Ethereum `prevrandao`
* claim state values
* contract-specific values

उद्देश्य यह है कि किसी एक random element पर निर्भरता कम हो। User या operator किसी single input से result को आसानी से control न कर सके।

Randomness design को public documentation, contract verification और probability table hash के माध्यम से समझाया जाना चाहिए। इससे users attribute generation logic को बेहतर तरीके से verify कर सकते हैं।

## 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://doc.cryptostone.org/crypto-stone/crypto-stone-wp-in/gem-attributes/30_attribute_generation_and_randomness_verification.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.
