Protocol for a "secret" prediction market centered on the price movement of on-chain assets, with wagers concealed using a commitment scheme.
Events to be wagered on can be structured as: will the asset exceed benchmarkPrice at any point before eventDeadline?
Commitments are hashed with either a Yes or No choice and a blinding factor. Once the eventDeadline has passed, users can reveal their winning commitments in order to claim their winnings.
Winnings are calculated as a user's original wager, plus the losing pot multiplied by the proportion of the user's wager in the winning pot.
