Prove your supply chain is compliant (carbon, labor, sourcing) without any supplier ever exposing raw data. Suppliers run a zero-knowledge circuit locally; VeriProof only ever sees the boolean result and its cryptographic proof.
Big corporations must prove their supply chains are 100% compliant, green or ethically sourced. But sub-vendors refuse to share private data (pricing, volumes, facility figures) for fear of losing competitive secrets. VeriProof removes that friction: it turns a compliance claim into a mathematical proof. The enterprise defines an assertion (e.g. 'CO₂ per unit < 12 kg'); it compiles to a zero-knowledge circuit (groth16 · bn254). Each supplier runs it against their own data, on their own machine, and returns only a verifiable proof, never the numbers behind it.
- Supply-chain overviewA live network map of every supplier (verified, pending, expired or failed) with fleet-wide compliance coverage, proofs this month and expiring attestations at a glance.
- Requirement builderA 4-step wizard: pick a standard (ISO 14064-1, GHG Scope 3, SA8000, OECD Due Diligence, FSC Chain of Custody, RBA), state the assertion in plain language, set proof expiry and re-attestation cadence, then publish and invite suppliers.
- Local, private proof generationSuppliers connect PostgreSQL, Snowflake, SAP ERP or a CSV, the connection stays on their machine. The circuit builds a witness and proves offline. Credentials and raw rows never reach VeriProof's servers.
- Trust boundaryEvery proof shows exactly what was disclosed (carbon intensity, standard, freshness, supplier identity) versus what stayed sealed (absolute emissions, production volumes, facility breakdowns, invoices), provably excluded from the proof.
- Tamper-evident audit logAn immutable event ledger, SHA-256 hash-chained and anchored on-chain. Any tampering breaks the chain and is detected on export to CSV/JSON.
- Attestation inboxSupplier side: 'Acme is asking you to prove 3 assertions', you reveal nothing but the result, with due dates and cadence.
Compliance and data privacy, no longer in conflict.
