How this service works
Verify a genesis402 signed receipt — signature and hash-chain position — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with: a boolean verdict ('valid'/'invalid'), signature_valid flag, the receipt's sequence number and SHA-256 hash, truth labels (e.g. ATTESTED, VERIFIED), the issuer's algorithm and key ID, chain anchor status, total receipts on chain, and the receipt version string.
Example use cases
Audit a payment attestation receipt
“I received a genesis402 proof receipt with ID 'pT8nA4cDqW2sF6mH' from a vendor — can you check if its Ed25519 signature is valid and whether it's been attested in the UnyKorn hash chain?”
Automated pipeline receipt integrity check
“Before I finalize this workflow step, verify that genesis402 receipt 'Yz5JkR1bXvM9eNqU' is valid and shows ATTESTED in its truth labels.”
Dispute resolution receipt confirmation
“We have a dispute about whether a transaction was recorded — verify genesis402 receipt 'Lw7GcS3tHnP0dK4V' and tell me its chain sequence number, anchor status, and whether the signature checks out.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/verify-receipt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to cryptographically validate a genesis402-format proof receipt, specifically checking Ed25519 signature authenticity and hash-chain sequence position within the UnyKorn Operator Network. Prefer it over generic hash-check tools when you need structured truth labels (ATTESTED, VERIFIED) and issuer key metadata from the genesis402 receipt schema.
Side effects
- Receipt ID not found — found: false returned
- Invalid receiptId format (must match ^[A-Za-z0-9_\-]{4,80}$) — request rejected
- Signature verification failure — verdict: invalid, signature_valid: false
- Network or upstream node unavailability — HTTP 5xx error
- Malformed or tampered receipt data causing hash mismatch
