# NFT Horses

Like real-life racehorses, **zkRace horses have different traits** that define their **rarity,** **performance**, **cool-down time**, and ultimately **value**. They are **100% one of the kind**. A horse is a valuable asset that allows you to participate in races, complete missions, achievements and get points.

Every NFT horse has a set of **visible and hidden characteristics**:

* Visible: sex, color, shape, breed, breeding and racing cool-down
* Hidden: speed, stamina and reaction time

Speed, stamina and reaction time are the key factors of winning the race. Speed, stamina and reaction time can be speculated from horse's bloodline (parent genetics), and previous race statistics.

Example of NFT horse characteristics:

| **Horse properties** |           |
| -------------------- | --------- |
| Speed                | 60 / 100  |
| Stamina              | 80 / 100  |
| Reaction time        | 90/100    |
| Racing cool-down     | 5 min     |
| Breeding cool-down   | 14 days   |
| Sex                  | Male      |
| Bloodline            | Mix Breed |
| Generation           | 4th       |

| **Physical data**       |        |
| ----------------------- | ------ |
| Eye color               | Red    |
| Eye shape               | Type 2 |
| Body pattern            | None   |
| Body type               | Fit    |
| Body-color              | White  |
| Ears                    | Type 3 |
| Jaw                     | Type 0 |
| Additional head element | none   |
| Tail                    | Type 4 |

We use **NFT technology** to create and differentiate every horse in the game. **Horses are stored as NFT tokens**. **Horses can be obtained in NFT marketplaces** (in-game or third party) or **created through breeding**. 

Majority of NFT horse's data is visible to the public. Users can inspect horse appearance, check horse race history and bloodline. Family trees allow users to navigate through horse ancestry.

The **NFT horses have a level system**. The level will depend on the races participated, races won, and overall activity on the platform.  The horses can compete in hippodromes with same-level horses.

## 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://zkrace.gitbook.io/whitepaper/derace-platform/nft-horses.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.
