Independent check
Verify a sealed forecast
Paste a revealed forecast and its salt, and the published commitment hash. Your browser recomputes the SHA-256 fingerprint and tells you whether they match. Nothing is sent anywhere — the check runs locally.
The commitment scheme is SHA-256( salt_hex + "|" + forecast_text ) — the same computation used to seal the forecast. You can reproduce it in any SHA-256 tool and confirm the match independently.
