How Verification Works

1

Upload PDF or evidence bundle

Drop the signed PDF or the sealed evidence bundle (.zip) you received from SignaTrust. The bundle path validates more of the trust chain — sender, signers, audit trail, and timestamp — in addition to the on-chain anchor.

2

Parse and hash

For a PDF we compute its SHA-256 hash. For an evidence bundle we parse manifest.json and audit-trail.json, then recompute every file's hash against the manifest. Any tampering surfaces here before we even reach the blockchain.

3

Verify on blockchain + timestamp

We confirm the document's hash was anchored to the Solana blockchain AND co-validated by a qualified RFC 3161 timestamp from an independent Timestamp Authority — two independent trust roots proving the document existed in this exact form at the recorded time.
