Every document, every photo, every spec uploaded to Real Estate Ledger is cryptographically fingerprinted on the Constellation Network. The result is an immutable, tamper-evident chain of custody anyone receiving the record can verify independently.
Digital Evidence proves a document has not been altered since the moment it was uploaded. It is not a claim that the contents were accurate at upload. That layer of trust comes from who uploaded it — a homeowner, a builder under contractual warranty, or a licensed contractor — and the documentation practices around them.

What it does
Cryptographically fingerprints the file. Anyone receiving the record can compute the same fingerprint and confirm the file has not been altered since upload.
✗
What it does not do
It does not certify that the document was correct or truthful at the moment it was uploaded. That trust layer comes from the source — not the platform.
How it works
Layer 0 cryptography, sub-second latency, zero transaction fees.
STEP 01
Upload a document
PDF, photo, spec sheet, inspection report — anything that lives in the property record.
STEP 02
Fingerprint on the Constellation Network
A cryptographic hash of the file is committed to the Constellation Hypergraph. Layer 0 DAG architecture, 120-node production network, sub-second latency, zero transaction fees.
STEP 03
Encrypted at rest and in transit
The document itself is encrypted in storage and over the wire. Only the fingerprint sits on-chain.
STEP 04
Verify on demand
When a buyer, lender, or insurer receives the record, they can independently recompute the fingerprint and confirm the file has not been altered.
The network behind it
Constellation Network — production infrastructure used by the U.S. Army.
120+
Production node operators
10,000+
U.S. Army Panasonic Toughbook deployments via Iron SPIDR
6 years
Department of Defense collaboration
0 fees
Per-transaction cost
Constellation's Layer 0 DAG architecture (Hypergraph Transfer Protocol) underwrites both the U.S. Army Iron SPIDR deployment and Real Estate Ledger's Digital Evidence — the same cryptographic layer, the same network.
Why this matters for property documentation.
Buyers and buyer's agents
A photo of a roof inspection is worth more when it comes with a tamper-evident fingerprint than when it shows up unattributed in a Google Drive folder.
Lenders and insurers
Underwriters are paid to discount unverifiable evidence. A verifiable record gets you priced on the actual risk profile.
Builders and contractors
Defensible documentation reduces post-construction warranty disputes. The fingerprint chain shows what was installed and when.
HOA boards and property managers
Continuity across board turnover. Records are tamper-evident, not floating in someone's personal email.
