# Clearpool Oracles

### How it works

* Over the course of a periodic epoch, Oracles submit votes on the Clearpool IRM curve model parameters
* Votes outside the 1st and 3rd quartile are removed resulting in a truncated distribution for each parameter
* The weighted average of remaining votes is calculated and used to set each respective parameter for the subsequent epoch
* An Oracle’s weight is determined by the amount of CPOOL staked by/to each Oracle
* All Oracle's are rewarded based on the (Capped) Voting Power, and all votes are made public via the [Oracle Voting Results](/clearpool/how-it-works/cpool-staking/oracle-voting-results.md) page
* CPOOL rewards are distributed proportionally to the Oracle’s delegators with the Oracle itself retaining a % commission
* Oracles set the commission % themselves. This can be changed at anytime but will only take effect at the beginning of the following epoch
* If an Oracles stake drops below the minimum (see below) they will no longer be eligible to vote, hence no rewards will be distributed

{% hint style="info" %}
Voting power and rewards are capped at 15%. Rewards are shared amongst all stakers within an Oracle pool (staking to an Oracle with more than 15% of total staked CPOOL will result in a lower APR)
{% endhint %}

### Oracle Requirements

* Minimum CPOOL stake: 150,000 CPOOL
* Voting frequency: once every 2 weeks
* Max voting power: 15% of total CPOOL staked
* Commission rate. Set by Oracle
