Make a claim.
Prove it later.
Sealed locks any statement behind an immutable hash and reveals it on the schedule you choose. The hash is your receipt — proof that you called it.
How it works
Every claim follows the same path — from sealed text to public, verifiable proof.
Make a prediction about anything — markets, politics, technology, sports. Say what you believe will happen and when.
Your text is instantly hashed into a unique cryptographic fingerprint. The stored digest lets the later reveal be checked against the exact text and nonce that were sealed.
The original text is encrypted with AES-256-GCM and scheduled for your chosen reveal date.
When your date arrives, the claim is decrypted and published. Anyone can compare the published text and nonce with the stored digest to check they match what was sealed.
Three independent AI models search the web and evaluate your claim against real-world evidence. Each returns a verdict with sources.
The community weighs in. Claims that reach 80% agreement earn “Called It” status — building your forecasting track record.
