Context that stays
with the record.
Keep readings connected to the operator account, equipment, customer, and transaction. Retain reasons for corrections and cancellations.
MEASUREMENT + PROVENANCEData integrity for measurement workflows
Measurement.
Integrity.
Evidence.
Turn measurement data into a verifiable record. Preserve its context, protect its history, and share evidence that can be independently checked.

01 / The platform
The measurement is only
the beginning.
A number needs context. MetraCrypt is designed to preserve the record behind it—who recorded it, what happened, when and where, why, and for whom.
Context that stays
A history you
can check.
Integrity checks and digital signatures help detect changes to retained records and verify their signed origin.
INTEGRITY + SIGNED HISTORYEvidence that
travels with you.
Export a portable proof for independent checking. The free command-line verifier works without a MetraCrypt account or paid anchoring add-on.
PORTABLE + INDEPENDENT02 / How it works
Three layers.
One evidence trail.
Core integrity comes first.
External anchoring is your choice.
CORE
Capture & preserve
Capture records, retain signed history, check integrity, and export evidence. These capabilities operate without the blockchain worker.
Built inANCHORING ADD-ON
Commit & anchor
A separately installed worker batches records and submits commitments to Solana and Bitcoin through OpenTimestamps. Business records stay off-chain.
OptionalSTANDALONE VERIFIER
Export & verify
Check the signed record, its place in a batch, and available blockchain evidence. Use an independently trusted signer registry to verify identity.
Free verifierAnchoring can pause while core capture continues, as long as the MetraCrypt service remains reachable.
03 / Independent verification
Your data stays
with you.
The proof can travel.
Publish a cryptographic commitment. Keep the underlying business records off-chain. Share exported evidence with the people who need to check it.
Understand what a proof establishesUNDERSTANDING THE PROOF
Has the signed record changed?
Check its fingerprint and signature against the retained evidence.
Was it included in the commitment?
Verify the record’s inclusion in the committed batch.
When did the commitment exist?
A verified blockchain anchor provides a separate time bound from the recorded capture time.
Proof of integrity does not certify the physical reading, the truth of entered details, or an exact capture time. Exported proofs include business data; share them deliberately.

Technology preview · v0.12
The current release demonstrates capture, signed history, proof exports, and optional anchoring with simulated measurement data.
Physical instrument input is disabled in this release. Live blockchain operation and native Windows installation still require validation before production use.
