# 20. 长期参与修正

为了奖励长期参与者，可以根据质押期限适用 Lock Multiplier。

| Lock Type   | Lock Period | Mining Multiplier | Maturity Burn | Returned STONX | Cooldown |
| ----------- | ----------- | ----------------- | ------------- | -------------- | -------- |
| Flexible    | 无           | 1.00x             | 0%            | 100%           | 7 days   |
| Short Lock  | 90 天        | 1.05x             | 2.5%          | 97.5%          | 无        |
| Medium Lock | 180 天       | 1.12x             | 5%            | 95%            | 无        |
| Long Lock   | 365 天       | 1.25x             | 10%           | 90%            | 无        |

Flexible Lock 没有折旧销毁，但为了防止短期流动性过快进出，在 unstake 请求之后设置 7 天 cooldown 期。

长期锁仓不是强制条件，而是可选条件。用户可以选择无折旧的 Flexible 方式，只有希望获得更高 Mining Power 时，才选择伴随一定折旧销毁的长期锁仓。

该结构追求以下平衡。

| 选择         | 优点       | 成本      |
| ---------- | -------- | ------- |
| Flexible   | 自由参与，无折旧 | 7 天返还等待 |
| 90 天 Lock  | 略高的挖矿算力  | 2.5% 折旧 |
| 180 天 Lock | 中等水平挖矿算力 | 5% 折旧   |
| 365 天 Lock | 最高挖矿算力   | 10% 折旧  |

锁仓倍率最高限制为 1.25 倍。这是为了在合理奖励长期参与者的同时，防止特定大型参与者获得过度优势。

在锁仓期间，只要用户的 PoM 值达到所需阈值，也可以 claim Gem NFT。也就是说，锁仓限制的是 STONX 可返还的时间，而不是禁止 Gem NFT 的 claim。

## 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-cn/wa-kuang-xi-tong/20-chang-qi-can-yu-xiu-zheng-yu-flexiblecooldown.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.
