Staking formula

The stake reward amount is based on non-compounding APY and will be calculated using this formula:

Internally, the smart contract will burn staked XEN (i.e. remove them from the total supply permanently) in order to reduce the total supply of XEN tokens, recording the debt to the original stakeholder. Each Smart Contract will re-mint the original staked XEN tokens together with an extra 20% rewards as newly minted.

Note: 20% is used as example in this formula. The APY varies based on days since genesis. See the table here.
