Cryptographic Verification
Truth in Metadata
A neutral verification layer that produces cryptographic evidence packages for catalogs, corrections, and registrations — without integrations or system access.
A neutral verification layer that produces cryptographic evidence packages for catalogs, corrections, and registrations — without integrations or system access.
SMPT verifies metadata states using independent nodes. Each verification produces a timestamped evidence package that can be checked at any time.
This ensures that every catalog, correction, or registration update has a provable history — independent of any publisher, label, or rights system.
Every verification produces a self‑contained, immutable evidence package.
Evidence packages are immutable and can be verified at any time.
Kataloghub validates → HeyRoya corrects → VerseIQ compares → TrapRoyaltiesPro audits → SMPT verifies.
A continuous workflow where each layer produces a cleaner, more accurate catalog — ending with a verifiable evidence package.
SMPT uses independent verification nodes. Each node validates metadata states and signs evidence packages.
Node operators include rights specialists, auditors, and infrastructure partners.
Evidence packages are open to independent verification — anytime, by anyone.
