1. The Gap Between “Upload” and “Still There in 20 Years”

What happens with mainstream cloud What owners usually discover too late
A single provider keeps three copies in one jurisdiction. One new law, outage or ransom-attack and access can vanish overnight.
Data is protected by RSA/AES keys. New quantum computers can break those keys in hours.
Replication is fixed at 3× size. 200 % extra space you pay for even if you dont need it.

2. How Quantum-Safe Storage Works in Plain Language

Think of your file as a jigsaw puzzle that is never kept in one box.

  1. Encryption The file is locked with AES-256.
  2. Fragmentation & Equations Instead of storing the file, the system creates 20 unique math equations whose solution is the file.
  3. Spread These equations are written to 20 separate devices you can pin to Sweden only, “no US soil”, “EU only”, etc.
  4. Resilience Only 16 of 20 equations are required to re-solve the puzzle, so four complete sites can disappear and the file still opens.
  5. Heal Devices silently check each equation every few weeks; any error is auto-repaired from surviving pieces.

You keep using normal drag-and-drop, S3 apps or phone backups—none of this math is visible in daily life.


3. Side-by-Side Comparison

Everyday risk Dropbox / OneDrive / S3 block storage Quantum-Safe Storage
Hard-drive dies in one data-center You wait for human repair or restore from backup Storage layer notices, recreates missing piece in < 1 s.
National firewall or court order Whole account frozen in that country 16 surviving fragments in other countries still serve the file.
Tomorrows quantum computer leaks universal password All data decipherable Attacker must retrieve and break 16 separate keys stored on different hardware, in different legal systems.
Storage cost overhead Always 23× raw size 20 % overhead for 5-site failure tolerance.

4. Nothing Changes on Your Network

The technology rides the same internet you already have:

  • Up- and downloads still go over IPv4, IPv6, fiber, 5G or your home Wi-Fi.
  • Apps that understand the S3 API (most backup software, Nextcloud, mobile photo apps) talk to the system without extra plugins.
  • Browser links keep working because a small gateway translates HTTPS requests into the low-level fragment fetches.

Only where the bytes sleep is different—scattered across independent “ThreeFold nodes” instead of a single cloud warehouse.


5. Why Geographic Sovereignty Matters

When a photographer hands wedding photos to a Swiss client or a clinic stores EU medical records, the question appears:
“Which country can legally force access to this data?”

With Quantum-Safe Storage the answer is explicit:

  • “The file is mathematically split. The re-combination map never leaves my machine, eight fragments sit in Swiss homes, twelve in German households—none in the US cloud.”
    That turns compliance from a promise into a verifiable fact and keeps the file reachable even if trans-Atlantic cables fail.

6. For Tech-Minded Readers

  • Encoding: Forward looking code over AES-256-GCM gives 20 % redundancy, detect-and-repair bit-rot, and 50 MB/s sustained throughput.
  • Metadata: filename-to-fragment mapping stored in its own ZDB (append-only, history kept).
  • Proof-of-Storage: Nodes prove fragment integrity via zero-knowledge checksums every heartbeat.
  • Post-Quantum Upgrade Path: Retro-fits Kyber or similar post-quantum ciphers once industrialized, without user action.
