Verify against the live settlement layer
No authentication required. The service recomputes the receipt evidence, checks the sequence commitment, and confirms whether the event belongs to the recognized settlement chain.
Read proof policyReady to verify certificate
Recognitium will verify the receipt ID without asking for the original document.
Public verification · no login · no document upload
Verify offline. Zero network requests.
A self-contained page that recomputes the receipt evidence entirely in your browser. Works from file:// in airplane mode.
One event. One order. One portable proof.
Hash integrity
SHA-256 of every receipt field. Change one bit anywhere and the hash changes completely.
Chain seal
Sealed into the Recognitium chain: deterministic SHA-256 evidence, independently verifiable with standard tools.
Settlement evidence
The receipt binds payload, sequence position, timestamp, and chain transition into one verifiable proof.
Chain link
Each receipt links to the previous one. Delete or reorder a receipt and the chain breaks.
Envelope seal
The entire response is sealed with SHA-256 — no key, no signature. Modify any field and the seal breaks.
Temporal binding
Timestamp evidence is bound into the receipt. The sequence only moves forward.
You just checked someone else’s proof. Make your own.
Hash any file or text in your browser and settle it on the same chain you just verified against. The data never leaves your machine — only the hash does.
