Time Capsules

Open in 2050 without '404 Not Found'.

The Problem

Time capsules defeat their own purpose if the digital links inside them fail to resolve when finally opened.

Why The Eternal Tier Responds Intentionally

The recovery key mechanism gives the capsule opener a way to recover the last anchored destination even if the original hosting stack changes.

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 graduating class of 2026 seals a capsule with a QR and recovery instructions for the destination.

Future-proof your time capsules

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.
