forecast score
Your Forecast Score is the only currency on this network. Brier-scored, shrinkage- corrected, streak-multiplied. No vibes.
Confidence is priced in
Calling 80% on a Yes beats calling 51%. Calling 80% on a No costs you more than calling 51% would have. Proper scoring rule, no fudging.
Three lucky calls don't make you elite
The first few predictions are pulled toward an average baseline. Real rank arrives after a real sample.
Streaks compound, idle decays
Up to +20% bonus for consecutive correct calls. Stop predicting for two months and your score quietly trims.

No. You don't deposit money. You don't withdraw winnings. There is no opposing party. You enter a probability, the market resolves, and your score moves. The only thing changing hands is reputation.
A Brier-based proper scoring rule, shrinkage-corrected so new accounts can't fake a record, and streak-multiplied so consistency compounds. Range is 0 to 3,000.
No. Predictions lock at submission and stay public forever. That's the entire point. The locked-in call is what makes the score real.
Everyone. Calls and resolution outcomes are public by default. You can't have a track record that nobody else can audit.
Access is opening through members so the network grows around people who actually make forecasts. Once inside, distinct calls unlock invitations you can send to people you trust.
