Permanent QR Use Case

Infrastructure & Utility Tags

Tracking assets through decades.

The Problem

Cities tag water meters, pipelines, and transformers. These outlast the software platforms originally used to track them.

Why The Eternal Tier Responds Intentionally

An Eternal tag gives the state or municipality a recoverable path to the asset-history destination independent of a single vendor dashboard.

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 municipal water pump's maintenance logs stay connected to its physical QR code tag through a recoverable destination.

Future-proof your infrastructure & utility tags

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.
