Sign and seal your published content — text, images, video — with post-quantum ML-DSA-65 (NIST FIPS-204) + on-chain timestamp. Readers instantly verify it's authentic and unaltered. The world's first sovereign post-quantum content-authenticity layer.
🔒 The content is never uploaded — only its SHA-256 hash, computed in your browser (Law #12 · privacy). Open source, sovereign, zero third parties.
AI can now fabricate text, images and video that look real. Screenshots are edited, quotes are faked, articles are altered after publishing. Readers have no way to know what a creator actually published — and classical signatures will break against quantum computers.
When you publish, you seal the content: its SHA-256 hash is signed with post-quantum ML-DSA-65 and timestamped on-chain. A tiny badge on your page proves it's genuine. If a single character, pixel or frame changes, the hash changes and verification fails ❌ — deepfakes and edits are caught.
Your content is hashed locally (SHA-256). Only the 64-char hash leaves your device. We sign it with ML-DSA-65 + timestamp + on-chain anchor and issue a public seal_id.
Add one <script> tag. Readers see ✅ Content Verified · INKG Truth Layer, linking to live verification.
A reader re-hashes the content and checks it against the seal. Match → AUTHENTIC ✅. Any alteration → ALTERED ❌.
Image, video, PDF, document — hashed in your browser
🔒 Content never leaves your device — only the hashAfter sealing, drop this one line where you want the badge (open source, works on any website — Law #16):
