There are 3 ways to earn FOAM tokens:
As the owner of a POI
As the challenger
As a voter
And you can earn 2 types of payouts:
bonuses
rewards
A bonus is given to the winner of the challenge: the owner of the POI or the challenger.
After the vote reveal period has concluded, the amount that was staked plus a bonus is paid to the winner.
Rewards are shared with everyone who voted on the winning side.
After the stake and the bonus is accounted for, the rest of the reward pool is divided between those who voted on the winning side.
All votes are token-weighted and receive an equal amount of the reward pool. This means that cartographers that vote with a higher amount of voting credit receive a higher portion of the reward pool.
