KGP tool

Verify an evidence object

Recompute the sha256 content hash of a claim and confirm it matches its Kinetic Gain Protocol evidence object. Everything runs in your browser. Nothing is sent anywhere.

1Read claim_text

Paste a KGP evidence object (or any JSON with claim_text + verification.content_hash)

Or hash any claim

Claim text → its sha256 content hash

What this checks, honestly. This tool verifies Level 2, content integrity: it recomputes the sha256 of the exact claim text and confirms it matches the evidence object. A match proves the text was not altered since it was hashed. It does not prove the claim is true, and it does not yet verify the Level 3 ed25519 signature, that requires the kgp-verify library (canonical JCS + signature check), which is being published. A signature proves who stands behind a claim, not that it is correct.
