Proof for the day someone asks.

Sealed when saved, chained to the record before, sent to Bitcoin’s public timestamping within about 10 minutes.

When you have to prove it

Without a record nobody can change, it is your word against theirs.

  • An injury claim

    What was reported, by whom and when, written that day.

  • An OSHA inspector asks

    Injury logs are kept 5 years, and copies are due within 4 business hours of a request. (29 CFR 1904.33, 1904.40)

  • “The work was never done”

    Card customers can dispute a charge for work not delivered as agreed. (12 CFR 1026.13) Dated photos and the customer’s own sign-off are on the record.

  • An insurer wants maintenance proof

    Every inspection and repair, logged when it happened, photos attached.

  • A lawsuit tests your records

    Federal courts let a qualified person certify a copy by its hash. (Fed. R. Evid. 902(14)) Losing records you should have kept can bring sanctions. (Fed. R. Civ. P. 37(e))

  • A regulated audit trail

    FDA’s electronic-records rule names secure, computer-generated, time-stamped audit trails. (21 CFR 11.10(e))

  • A security-deposit dispute

    Move-in and move-out photos, each dated and sealed.

  • Disaster cost reimbursement

    FEMA Public Assistance can’t fund costs an applicant can’t show are eligible. (PAPPG v5.0)

  • An employee dispute

    Warnings, training and sign-offs, each with who and when. After a discrimination charge, relevant records are kept until it ends. (29 CFR 1602.14)

  • A buyer’s due diligence

    Years of records a buyer can check, not just take your word for.

Fifteen layers, live today

Every layer below works today.

  1. Chained

    Each record carries the SHA-256 fingerprint of the one before. Change or remove one, and the chain breaks.

  2. Sealed at Submit

    No edits, no deletes. A correction is a new record, and both stay.

  3. Fixed in Bitcoin

    Every 10 minutes, each company’s newest fingerprint goes to three OpenTimestamps servers; Bitcoin confirms it some hours later.

  4. Check it yourself

    Anyone can look up a fingerprint on the Check a record page, no login. The Bitcoin proof file checks with the free OpenTimestamps tools.

  5. Files fingerprinted to the byte

    Each stored photo or document gets its own SHA-256 fingerprint. Change one pixel, and it no longer matches.

  6. Device-Lock

    Optional: a code alone is not enough, the person also unlocks their own phone or computer.

  7. Confirmed from outside

    A customer gets a one-time link. Their “received” or “dispute” is written into your ledger, with the time.

  8. Precise location

    When the box is ticked, the phone’s position is sealed into the record’s fingerprint.

  9. Content Credentials read

    If a photo carries Content Credentials (C2PA), Cibotti reads them and shows who signed it.

  10. Backed up

    A copy of the database every night. A second copy of every file, made every hour.

  11. Cibotti time proof

    Each new record carries a public number nobody could know in advance, so it cannot be backdated.

  12. History locked

    The database itself refuses to delete or change a past record.

  13. Official time stamp

    Each Bitcoin stamp also gets an RFC 3161 time stamp from a public time-stamping authority.

  14. Offline checker

    Check a record on any computer, without us.

  15. Record pack

    Records, files and fingerprints in one download, for your records custodian to certify.

What a record proves

PROVES

  • Who wrote it.
  • When.
  • That it has not changed.
  • That no earlier record was quietly removed.

DOES NOT PROVE

  • That what it says is true.

General information, not legal advice. How a rule applies to you, and what an inspector or court decides, depends on the facts.

Don’t trust us. Check.
