A blind, multi-outcome parimutuel prediction market. Size shown, side sealed, settled on-chain. Non-custodial.
It's parimutuel: there's no house and no bookmaker setting odds. Everyone's stake goes into one pot. When the event resolves, the pot (minus a 2% fee) is split among whoever backed the winning outcome, pro-rata to their stake.
The twist is blind: while betting is open, every bet is encrypted. You can see the pot size, but not who backed what. No live odds, no order book, nothing to copy. Back a winner few others did and you split a fatter pot — the crowd can't pile onto your read and crush the payout, because they can't see it.
choice‖nonce with timelock encryption (drand), and submits the
ciphertext plus a hash commitment. Your stake (USDC) is escrowed by the contract.Non-custodial. Funds sit in the contract; payout math is fixed in code. We can't touch your stake or change who won. Reveals are verified against on-chain commitments, so picks can't be forged.
A keeper must decrypt and reveal bets before each market's deadline. It can't steal funds — but if it goes down and bets aren't revealed in time, those stakes are refunded/forfeited rather than counted. One job: stay alive.
If a market's winning side has no revealed stake (e.g. the keeper failed), the contract voids it and everyone is refunded in full — funds can't get stuck.
A flat 2% is taken from the pot on a resolved market — 0.5% to the market creator, 1.5% to the protocol. Voided markets take no fee. The multiples you see are always after the fee, so the number on the receipt is the number you get.
