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.

$AIKING inflation is structured in the following way: * Year 1: 70% * Year 2: 20% * Year 3: 7% * Year 4: 3%
