Integrity Layer
Data in TraceWeave. Cryptographic seals on Polygon. Immutable proof of critical versions (DPP, supply chain, reports) for defence against audits, investors and greenwashing.
Process
How it works
Every critical event, sealed and chained. Alter one data point and watch the chain break.
Your data
private · GDPR
Fingerprint
public · Polygon
Each critical event is sealed with its fingerprint and chained to the previous one. The data stays in TraceWeave; only the fingerprint travels.
Any alteration breaks the chain and is detectable. Independently verifiable, forever — without trusting TraceWeave.
Verifiable on PolygonscanCritical events · chained
The four fingerprints match the anchored ones. The chain is intact.
Infrastructure
Why Polygon?
We chose Polygon PoS for its alignment with the textile industry's ESG values.
Proof of Stake vs Proof of Work. Minimal consumption verified by CCRI.
More than half of validators run on 100% renewable energy.
Verified commitment. Only 56 tCO₂e per year. MiCA-ready dashboard.
Proven infrastructure. Adopted by global brands and auditors.

Data off-chain. Proof on-chain.
An architecture that maximises trust and minimises complexity.
- Every operation on-chainOff-chain in a database
- Proof over the entire datasetSeals only for critical milestones
- Complex architectureSimple: database + optional seals
- High cost (every tx on-chain)Controlled (selective events)
- Blockchain mandatoryOptional (high-compliance only)
TraceWeave does not put the entire operation on-chain: it only anchors the fingerprint of critical milestones. The same integrity proof, without the complexity or cost of a blockchain-first architecture.

Verified ESG score
Metrics anchored on Polygon
Verified integrity
Supplier certification
Tamper-proof audit trail
Certifiers demand proof that data hasn't been altered. Every critical version is sealed with a cryptographic fingerprint anyone can verify independently.
Impact metrics with cryptographic backing
Responsible capital demands verifiable impact data. CO₂, water and energy metrics are anchored to an immutable fingerprint the investor validates on their own.
Data integrity for demanding chains
Large retailers require verifiable sustainability data from their suppliers. Your brand proves compliance with evidence that withstands their scrutiny.
Sealed CSRD datasets for due diligence
In an acquisition, the committee asks whether the ESG data is real. CSRD datasets are sealed with a fingerprint the buyer's auditor can verify.
Built for enterprise
Your data never touches the chain
Off-chain, under your control. On-chain, only a fingerprint no one can forge.
Off-chain, encrypted in your own infrastructure. Data never leaves your systems.
Only the SHA-256 fingerprint is anchored — never the content or any personal data.
Zero-knowledge by design. No identifiable data reaches the public chain.
You decide which versions are sealed and who you grant verification access to.
No lock-in: the proof is verified independently, without depending on TraceWeave.
Polygon PoS, public and auditable. Anyone can check the anchoring on their own.
Verifiable without trusting us: your data stays with you and only a fingerprint no one can forge travels to the chain. GDPR-compliant, no lock-in and independently auditable.
