Published Books & Print

Permanent links for physical print runs.

The Problem

Millions of printed books contain hardcoded URLs to author sites or errata that break a few years post-publication.

Why The Eternal Tier Responds Intentionally

Like an ISBN, a paid Eternal QR code provides a persistent routing address plus a recovery path integrated directly into the print.

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

A textbook's appendix QR points to always-updated online homework, outlasting the publisher's site migration.

Future-proof your published books & print

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.
