Verifiable proof for the third parties that matter
Auditors, investors, retailers. Immutable data with blockchain anchoring, audit-ready packages in hours.
"They ask for proof and I can't prove anything"
Auditors, investors and retailers demand verifiable evidence. Without an immutable record, every due-diligence request turns into weeks of manual work and reputational risk.
- Audit = weeks of preparation
- Retailers demand verifiable certifications
- Investors require sustainability due diligence
- I can't prove my data wasn't altered
Data that speaks for itself
Anchoring on a public blockchain. Immutable hash. Independent verification by any third party.
DPP data
Products, supply chain and impact: the state of your data, captured automatically.
Integrity Layer
SHA-256 hash of each version, anchored on Polygon PoS. Sensitive data never leaves your platform.
Verifiable proof
Audit-ready package with a public link: any third party verifies without access to TraceWeave.

Integrity Layer is not just a record on blockchain. It's a verifiable trust layer that turns internal data into auditable evidence for third parties.
Frequently asked questions
- Which blockchain do you use?
- Polygon PoS, a public, carbon-negative blockchain with low cost per transaction. Sensitive data is never on-chain, only cryptographic hashes.
- How do I verify a proof?
- Each audit-ready package includes a publicly verifiable link. Any third party can confirm that the hash corresponds to the original data without needing access to TraceWeave.
- How long does it take to prepare an audit?
- Hours, not weeks. Once your data is in TraceWeave with Integrity Layer active, generating an audit-ready package is a matter of clicks.
- Is it enough for certifiers?
- The system is designed specifically to satisfy audit requirements. Immutable hashes, change timeline, and independently verifiable proofs.
