Permanent QR Use Case

Scientific Datasets & Citation

A DOI for the physical world.

The Problem

Link rot in scientific papers severely degrades reproducibility when referenced datasets 404.

Why The Eternal Tier Responds Intentionally

An Eternal QR printed in a physical journal keeps the dataset destination recoverable even if project websites move.

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 researcher includes a verifiable QR in their poster presentation, linking reliably to their supplementary data repository.

Future-proof your scientific datasets & citation

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.
