## Description

Certificates for glass, ceramics, and building materials are critical documents: they prove quality and safety properties. Forgeries endanger lives and lead to costly reconstructions.

Blockchain certificate security: The inspecting body anchors the certificate hash on-chain; the QR code on the certificate enables immediate verification; revocation is visible on-chain. Relevant for thermal insulation glass, fire protection glass, and structural glass with critical safety parameters.
