iBlock Verify / Interactive demo

Same file. Clear evidence.

Try a document check without an account. Compare bytes, then read issuer trust and record status separately.

Step 01

Choose a scenario

Synthetic scenario

Compare the original bytes with the synthetic reference fingerprint.

Step 02

Compare a file

SHA-256 and the salted commitment are computed in your browser using the same algorithm as Verify. File contents, names, fingerprints and salts are never sent by this demo.

Or download the synthetic original and changed copy, then select either file below.

Choose a file to compare (up to 25 MB)

Local integrity: Not checked

A match proves the bytes match this synthetic reference. It does not prove the document’s claims, issuer authority or legal validity.

Step 03

Read the evidence separately

Chain evidence: Simulated anchor present
Issuer trust: Fictional reviewed issuer — simulation
Record status: Active record — simulation
Legal validity: Not assessed

Revocation changes a record’s status, not its file fingerprint. Unknown issuer trust stays unknown even when the bytes match. “Active” describes a record, not a legal conclusion or an expiry check.

In a real check, chain receipts and the latest issuer and revocation information must be read from their sources. This demo cannot check an existing public proof.
