How it works
Sites embed seal.js
Any website can add a single script tag to declare their compute receipts. It's one line of code.
Extension detects the seal
When you visit a page with seal.js, the extension automatically queries the Proven registry for verification status.
Green shield = verified
A green shield appears in your toolbar. Click it to see full cryptographic details — algorithm, integrity, semantic checks.
The trust flywheel
Every participant in the ecosystem strengthens it for everyone else.
