One way in. No way out.
Records are written once. They can be referenced, verified, and quoted — but never altered, never quietly removed. The vault keeps a photograph the way a museum keeps a negative.

the deep vault
A photograph, sealed
the moment it’s taken.
Watermarkchain is the deep vault for real photographs — an append-only ledger where every shot is witnessed, fingerprinted, and kept. One record per photograph. No edits. No deletions. For as long as the lights stay on.

Witnessed by many, not centrally controlled.
Every seal is co‑signed by an independent ring of witness nodes. No single server, no single party, can revise the past. If it’s in the vault, it’s in the world.
Built to outlive any one party.
The vault is its own thing. Replicated across geographies, mirrored in cold storage, designed to keep reading thirty years from now — with or without whoever put the photograph there.
How a record is sealed
STEP 01 · CAPTURE
The shutter fires.
Pixels, timestamp, GPS, device, lens, and capture mode are bundled at the source — before the photo ever leaves the camera.
t=0.000s
STEP 02 · FINGERPRINT
A unique signature is taken.
The bundle is hashed into a short, unforgeable fingerprint. Change one pixel and the fingerprint changes. The photo itself stays where you keep it.

STEP 03 · WITNESS
The ring co‑signs.
Independent nodes each verify the fingerprint and add their own seal. The record is now anchored across the ring — tamper‑evident by design.

STEP 04 · ARCHIVE
Into the vault.
The signed record joins the chain and is replicated to long‑term mirrors. From this moment on, the photograph has a place in the public record.
