# Equations

## Mint Price Formula

The discounted mint price is set to encourage QLT minting. The mint price formula is,

$p_{mint}$: the QLT mint price. $p_{market}$: the market price. $discount_{mint}$: the discount rate of minting.

## Staking Rewards Formula

### QLT Reward

Different staking plans have different reward rates. The longer the commitment period, the higher the reward rate. The formula to calculate the amount of rewarded QLT is shown below.

$Reward_{stake}$: the amount of rewarded QLT. $q_{staked}$: the staked QLT amount. $r_{stake}$: the hourly staking reward rate.

### Airdrop Reward

The airdrop reward is planned to be released on a monthly basis three months after launch. A QLT staker is entitled to the airdrop reward only if he keeps staking QLT until the release of the airdrop reward. The airdrop reward is calculated as:

$Reward_{airdrop}$: the airdrop reward entitled to the staker.

$\sum staking\_power_{i}$: the sum of all QLT stakers’ staking power.

$Q_{airdrop}$: the total amount of airdrop.

### Staking Power

Generally, a longer staking commitment period corresponds to a higher staking power multiplier.

## APY Calculation

Staking rewards are calculated to derive the annual percentage yield (APY).

$r_{stake}$: the hourly staking reward rate, and 8760 is the number of hours per year.
