How your data is stored, how signatures are proven and which documents govern the service.

Three layers of evidence

Data integrity, signature evidence and approval evidence.

Each layer leaves an artifact you can check: a report with a verdict, a certificate with a verification ID, a snapshot of who approved what.

  • Integrity report

    Data integrity

    Two canonical ownership engines, an append-only equity ledger and an integrity report with a verdict.

  • Certificate of completion

    Signature evidence

    Hashes, identity, time, device, consent text, stroke image, hash chain, an executed PDF with a verification ID and QR code, and a certificate of completion — verifiable on a public page.

  • Approval snapshot

    Approval evidence

    Append-only snapshots of who approved what and when; executing the corporate action is a separate confirmation with its own preview and hash.

Fields recorded for every signing and what each one proves
FieldPurpose

Signer identity and confirmation methodShows who signed and how the identity was confirmed: e-mail code or passkey
UTC time of each actionFixes when the document was opened, confirmed and completed
IP address and device informationRecords where and from what device the action was taken
Consent text and versionKeeps the exact terms the signer accepted
Handwritten stroke imageStores the visible signature for the NX Strong level
Hash chain of evidenceEvery record includes the previous one, so the sequence cannot be rewritten
E-mail and view logShows when invitations were sent and when the document was viewed
