# Validator Commission Changes

> Records of validator commission rate changes on Monad

This table tracks all commission rate changes by validators on the Monad network. Commission is the percentage of block rewards retained by the validator before distributing to delegators.

## Table Schema

| Column Name                 | Data Type | Description                                                                    |

| block\_timestamp            | TIMESTAMP | Timestamp of the block containing the commission change                        |
| block\_number               | INTEGER   | Block number containing the commission change                                  |
| block\_hash                 | VARCHAR   | Hash of the block containing the commission change                             |

## Understanding Commission

Validator commission affects delegator returns:

* **Commission Rate**: Expressed as a decimal (e.g., 0.10 = 10%)
* **Delegator Impact**: Higher commission means lower delegator rewards
* **Competitive Factor**: Validators may adjust commission to attract or retain delegators

## Sample Query

Track commission changes for all validators:

```sql theme={null}
SELECT
  validator_id,
  auth_address,
  old_commission_percentage * 100 as old_commission_pct,
  new_commission_percentage * 100 as new_commission_pct,
  (new_commission_percentage - old_commission_percentage) * 100 as change_pct,
  block_timestamp
FROM monad.staking.validator_commission_changes
ORDER BY block_timestamp DESC;
```
