Permanent QR Use Case

Certificates & Diplomas

Verify credentials years into the future.

The Problem

When a university or training center restructures its website, verification links on paper diplomas break.

Why The Eternal Tier Responds Intentionally

The QR code printed on the certificate can point to an anchored verification record. Future employers have a recovery path for the last destination.

Cryptographic AnchoringUnlike the Free/Basic hosted tier, the paid Eternal tier writes an encrypted routing payload to Base L2. Eternal QR derives and exports a per-user recovery key so the last anchored destination can be decrypted without the Eternal QR servers. Basic operates on traditional infrastructure and does not include blockchain anchoring.

Real-world Example

Graduates can keep a long-lived QR link from a paper diploma to the institution's verification page.

Future-proof your Certificates & Diplomas

Stop leaving a critical digital legacy entirely in the hands of generic SaaS tools. Add Base anchoring and recovery-key export with the paid Eternal tier.
