What is No-loss Lottery?
No-loss Lottery Pool offers a chance to win prizes in exchange for depositing funds. Even if you don't win, you keep all your deposited funds. Prizes are made up of the interest that accrues on all user's deposits.
Where does the money for the prize come from?
When you join a prize pool, your money is deposited into a yield source. The yield source generates the return that makes up the prizes.
What prevents people from depositing right before a prize and withdrawing right after?
When you deposit into a prize pool, you are instantly eligible to win. This creates a possibility for people to abuse the system by depositing right before a prize, having a chance to win, and withdrawing right after.
The protocol prevents this by enforcing a temporary early withdrawal penalty. This means if someone deposits and immediately withdraws, they will have to pay a penalty that will go to the next prize. Over time this penalty reduces to zero.
