# $AIKING Index Pool
## What is Index Pool?
**Index Pool** is a weighted portfolio of tokens of agents launched on the ARCHAI platform. **$AIKING** is a reward token for staking on ARCHAI meaning you will claim it as a reward for staking. **$AIKING** represents the value of the index pool based on values of deposited tokens. As well as $ARCHAI, it can be traded on secondary markets.
## $AIKING distribution
You get $AIKING as reward for [staking](/archai/staking.md) $ARCHAI.
Reward distribution is linear and proportional to one's staked amount. As an example, if your stake is 10% of the total stake, you will get 10% of total rewards.
Reward distribution is executed by the staking smart contract and is defined by two parameters: *amount of rewards* distributed *each second;* and *epoch*, which is a time frame for the distribution with given rewards per second. You can check current values in the staking contract.
Over the first month 112,000,000 $AIKING (11.2% of total supply) will be distributed pro-rata between stakers.
Each epoch (month) amount of $AIKING distributed to $ARCHAI stakers will decrease according to the table below.
Table 1: $AIKING Distribution
$AIKING inflation is structured in the following way:
* Year 1: 70%
* Year 2: 20%
* Year 3: 7%
* Year 4: 3%
