Document Verification

Check an institutional provenance reference.

Approved recipients can upload a document, scan a Bridge28 QR code, or enter an audit reference / document number to identify the sealed record and authenticate the document hash without exposing private deal-room content.

Upload actual documentSHA-256 is calculated locally before comparison with the sealed Bridge28 record.

Reference lookupQR payload, audit reference or document numberUse the reference printed on a Bridge28 receipt, QR code or audit record.

Verification Architecture

Hash-only proof, consent-controlled disclosure and identifier lineage.

Hash-chained ledgerEvery event is sealed with SHA-256 into an append-only record.

Merkle-proof verificationAny document or decision can be independently proven without exposing private content.

Identifier lineageOne thread runs from registration (REG) through transaction coordination (TC) to settlement (TXN).

Consent-controlled disclosureNothing is shared without a recorded consent event.
