# Unbond(a.k.a. Exit) Mechanisms

## Instant Exit vs. Linear Exit

iOS holders have two exit options:

### **Instant Exit**:

* iOS can be instantly unbonded to OS at any time
* 50% penalty applies (1 iOS = 0.5 OS)

### **Linear Exit (Vesting)**:

* 6-month linear vesting option available
* Can be canceled during the first 14 days after vesting starts
* iOS in vesting cannot vote and does not receive rebase rewards

## Exit Penalties and Distribution Method

Exit penalties are distributed to remaining participants in the system:

* **Distribution Mechanism**: Forfeited OS tokens are distributed proportionally to iOS stakers based on their share
* **Distribution Method**: Penalties can be claimed during the next epoch

## PVP Rebase

We call this exit penalties redistribution as "PVP (Player vs Player) Rebase":

* **Dilution Protection**: Stakers are partially protected from dilution through early exit penalties from other users
* **Natural Value Concentration**: Ownership naturally concentrates among users who value it most over time
* **Incentive Alignment**: The structure rewards longer stays with more rewards, promoting long-term participation.&#x20;
