I stayed up all night going through Sign’s documentation and came away with a different perspective: the project isn’t just building proofs for display, but proofs that can be traced back to their source.
Most “proofs” today feel cosmetic—they show up as badges, visible credentials, or verification marks that reassure users on the surface. They communicate trust, but they rarely go deeper. Other applications often can’t tell where the proof originated, which schema it follows, who issued it, or whether it’s still valid or has been revoked.
$SIGN takes a different approach. Its schema defines a shared structure for claims. Attestations are recorded against that schema. Then an indexing and query layer makes those proofs discoverable, verifiable, and reusable across systems instead of leaving them as static displays.
That distinction matters. When a proof can trace its origin, expose its logic, and verify its current status, it starts to function as infrastructure for trust. Otherwise, it remains just a better-looking signal.
