The problem with your data

Every record your business creates can be changed.
Most never should be.

Contracts, sensor readings, CMR documents, machine logs, delivery confirmations — the moment they're written to a standard database, anyone with access can alter, delete or overwrite them. Intentionally or by accident. Silently. Without a trace.

🔗
How we solve it

One cryptographic chain. Every piece of data. Forever.

We pull all your data — documents, sensor readings, machine logs, signatures — and lock them together into a single, tamper-proof, court-ready record. No IT overhaul. No new infrastructure.

1
Ingest
Your data arrives — documents, sensor streams, API events, manual uploads. Any format, any system.
ERP · TMS · sensors · API
2
Encrypt & Hash
Every record is encrypted with AES-256 client-side, then fingerprinted with SHA-256. Content stays private. Integrity is provable.
AES-256 · SHA-256
3
Lock & Anchor
Hashes are written to WORM storage and anchored on Hyperledger Fabric. Once written, nothing can ever change — not even us.
WORM · Hyperledger · TSA
4
Prove
One QR code or search gives you the complete dossier — hashes, timestamps, signatures, audit trail — ready for court, audit or dispute.
Merkle proof · eIDAS · evidence bundle
What gets locked together — per event, per transfer, per record
📄
Documents
CMR, contracts, delivery notes, certificates — cryptographically sealed at the moment of upload
🌡️
Sensor data
Temperature, humidity, GPS, pressure — timestamped per reading, linked to the dossier
✍️
Digital signatures
eIDAS-qualified signatures at every transfer point — legally binding across the EU
🔍
Full audit trail
Every view, edit, download and event — hash-chained so no event can ever be removed or altered
Why standard databases fail you
The CRUD problem
Every database on earth runs on CRUD: Create, Read, Update, Delete. That means any record — including yours — can be changed or erased. Deliberately by a bad actor, accidentally by a colleague, or silently by a system migration. Our immutability layer makes all of that impossible.
❌  Standard database (CRUD)
✏️Records can be updated after the fact — a colleague saves the wrong version, a temperature reading gets "corrected"
🗑️Records can be deleted — accidentally or intentionally — a CMR disappears, a log entry is gone
💥A system migration, server crash or ERP update silently corrupts or loses historical data
👁️No proof of who changed what — or even that a change happened at all
⚖️In court or audit, you cannot prove the original state of any record
😰Disputes drag on — no single source of truth everyone can verify independently
✓  With our immutability layer
🔒Records are locked at creation — corrections add a new entry, the original is always preserved
♾️Nothing can be deleted — WORM storage makes it physically impossible, intentionally or accidentally
🛡️Accidental changes are impossible by design — a wrong save creates a new version, the original is untouched
🔗Every action is hash-chained — tampering with any event breaks the entire chain instantly and visibly
📋SHA-256 hash + blockchain timestamp = court-accepted proof of the original state, forever
One QR code ends the dispute — independent verification without trusting anyone's word

What our platform protects — and why it outperforms traditional storage.

Three steps to making your data permanently trustworthy.

STEP 1

1. Blockchain Discovery


Map your data landscape — free consultation

We identify where data breaks, where trust is missing, and which processes benefit most from immutability.

We map your end-to-end data flows across every system (ERP, WMS, TMS, databases, cloud storage, legacy apps…) — without disrupting operations.

2. Try the Live Demo


See DocTracer work in minutes — no installation, no IT setup.

Test it directly with your own documents and document events:

  • Upload a document → automatic hashing + WORM storage
  • View document events (uploads, views, downloads, edits)
  • See the blockchain-anchored proof + timestamp in real time
  • Verify integrity with on-chain hash + Merkle proof

No commitment. No setup. Just proof it works.

Frequently Asked Questions (FAQ)

  • DocTracer makes every document — and everything that happens to it — permanently verifiable. The moment a file is uploaded, it's hashed, encrypted, timestamped and anchored on a private blockchain. From that point on, any alteration is immediately detectable. You get a complete, court-ready audit trail of every view, edit, download and signature.

  • Yes — in practice. DocTracer uses eIDAS-qualified timestamps and signatures, SHA-256 cryptographic hashing, and Hyperledger Fabric anchoring. This combination is designed to meet the evidentiary standards of EU courts, regulatory audits and legal review. We cannot guarantee outcomes in specific legal proceedings, but the proof we generate is built to the highest available standard.

  • No — and that's the point. Once a document is committed to DocTracer, it is stored in WORM (Write Once, Read Many) storage. It cannot be overwritten, modified or deleted — not by you, not by your team, not by us. Any correction creates a new version. The original is always preserved.

  • Your documents and their proofs remain stored independently. Verification is based on cryptographic hashes and audit data — it does not depend on DocTracer being online. Even if the platform were unavailable, your evidence bundles remain valid and independently verifiable.

  • At the exact moment it is uploaded and locked into the system — not when you created it on your device. The timestamp reflects when DocTracer received and sealed the document, anchored by a qualified TSA (Trusted Stamp Authority) and the Hyperledger Fabric ledger.

  • Access is controlled through role-based permissions: Admin, Uploader and Viewer. Every access event — including views, downloads and searches — is logged in the immutable audit trail. You always know who saw what and when.

  • DocTracer guarantees integrity and existence — not truthfulness. We can prove that a document has not changed since it was uploaded, and exactly when it was uploaded. We cannot verify whether the content itself is accurate or genuine. Think of it as a tamper-proof safe, not a fact-checker.

  • External anchoring links your document's cryptographic proof to a trusted third-party timestamp authority (TSA) or public ledger. This means verification doesn't require trusting DocTracer — any party can independently verify the proof using only the hash and the public anchor. It's the difference between "trust us" and "verify it yourself."
