Notch Protocol is experimental software. Predictions are not financial advice. Use at your own risk. Read full disclaimer
Where predictions are permanent.
Every prediction passes through three immutable stages. No backdating. No deletion.
Hash your prediction with a secret salt and submit it on-chain. Nobody can see it. Nobody can front-run it.
After the delay, publish the prediction and salt. Contract verifies the hash matches.
Oracle delivers the price at resolution time. Your Notch Score updates. Permanent.
The only protocol combining cryptographic commitment, calibration-aware scoring, persistent reputation, and tradeable instruments on verified skill.

Two-phase submission prevents front-running and copycat attacks. Predictions are hashed on-chain, then revealed after the window closes.
// Phase 1 — commit

Brier Score
0.1875
If you say 75% and you’re right 75% of the time, your Brier Score is 0.1875
Perfect calibration!
Lower is better. A Brier Score of 0.0000 means perfect predictions. A score of 0.2500 is no better than flipping a coin.
Not just accuracy. Calibration. When you say 78% confident and you're right 78% of the time, that's a perfect Brier score.
EMA of correct predictions. 0.95 decay — recent calls matter more.
Brier score. How well stated confidence matches outcomes.
Low variance in rolling accuracy. Steady beats lucky.
Log-scaled prediction count. Statistical significance.
