The bets are held in entirely decentralized escrow. The oracle reports the score and those who have stakes in the grid vote to confirm the oracle's score. Once a score is confirmed, the winnings are collected by the winners.
You pick a square and send a transaction to the ethereum network with your choice and the amount of ether you'd like to offer.
The contract tracks your wager as well as everyone else's wager.
I report the score 1 day after the big game.
Once I report the score, the community participating in the grid has 7 days to affirm it.
Votes are weighted by total stake in the grid. If you offer 0.3 ETH on one square and 0.1 ETH on another square, your total influence on the vote is 0.4 ETH.
7 days after I report the score, if 2/3rds of the voters agree that I was honest, anyone can accept the final score to release the winnings from escrow. Winners can visit the site to collect their winnings.
If I was not honest, I can correct the score and resubmit for approval.
