# 20 Long-Term Participation Adjustment

A Lock Multiplier may be applied according to the staking period to reward long-term participants.

| Lock Type   | Lock Period | Mining Multiplier (L\_i) | Maturity Burn | Returned STONX | Cooldown |
| ----------- | ----------- | ------------------------ | ------------- | -------------- | -------- |
| Flexible    | None        | 1.00x                    | 0%            | 100%           | 7 days   |
| Short Lock  | 90 days     | 1.05x                    | 2.5%          | 97.5%          | None     |
| Medium Lock | 180 days    | 1.12x                    | 5%            | 95%            | None     |
| Long Lock   | 365 days    | 1.25x                    | 10%           | 90%            | None     |

Flexible Lock has no depreciation burn, but a 7-day cooldown period is applied after an unstake request to prevent short-term liquidity from entering and exiting too quickly.

Long-term lock-up is not mandatory. Users can choose the Flexible method without depreciation, and only choose longer lock-ups with depreciation if they want higher Mining Power.

This structure seeks the following balance.

| Choice       | Benefit                             | Cost                        |
| ------------ | ----------------------------------- | --------------------------- |
| Flexible     | Free participation, no depreciation | 7-day return waiting period |
| 90-day Lock  | Slightly higher Mining Power        | 2.5% depreciation           |
| 180-day Lock | Medium-level Mining Power           | 5% depreciation             |
| 365-day Lock | Highest Mining Power                | 10% depreciation            |

The lock-up multiplier is limited to a maximum of 1.25x. This is designed to provide reasonable compensation to long-term participants while preventing any specific large participant from gaining an excessively advantageous position.

Even during the lock-up period, a user can claim a Gem NFT once their PoM reaches the required threshold. In other words, lock-up limits the time at which STONX can be returned, but does not prohibit Gem NFT claims themselves.

## 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/mining-system/20_long_term_participation_adjustment_and_flexible_cooldown.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.
