“We went from panic about EU compliance to becoming the first battery manufacturer with full Digital Product Passports. ProofPass made it trivial.”
“During the last E. coli scare, we traced back the contaminated batch to the exact farm in under 1 minute. Saved us $1.8M in unnecessary product destruction.”
“We caught 3 counterfeit incidents in the first month that our old system missed. One batch contained only 40% of the active ingredient. ProofPass literally saved lives.”
Supply Chain Compliance Without Compromising Data Security
Regulatory Requirements Intensifying
- EU Battery Passport (Feb 2027)
- FDA 48-hour traceability
- ESG disclosure mandates
- Penalties: Market exclusion, revenue fines
Manual Processes Don't Scale
- 50K-200K EUR annual audit costs
- Weeks to prepare documentation
- High error rates
- Fragmented data systems
Competitive Data at Risk
- Must prove compliance
- Cannot reveal exact figures to competitors
- Need to protect IP
- Privacy regulations (GDPR)
Industry Impact
Annual costs and fraud losses by industry
| Industry | Compliance Cost | Fraud/Year |
|---|---|---|
| Food & Agriculture | $50K-200K | $12B EUR |
| Battery/EV | $100K-500K | $8B EUR |
| Pharmaceuticals | $200K-1M | $15B EUR |
The Challenge: Organizations need to prove regulatory compliance without exposing sensitive competitive data. Traditional systems force you to choose between transparency and security.

Detailed examples of how companies use ProofPass to solve complex compliance and trust problems
EU Battery Passport Compliance by February 2027
EuroPower Systems produces 50,000 EV batteries per month. The new EU Battery Regulation requires a Digital Product Passport for each battery with full lifecycle data: carbon footprint, recycling content, supply chain provenance. Traditional paper certificates won't work at this scale.
- ✗Manual data collection from 15+ suppliers takes 2-3 weeks per batch
- ✗Cannot prove carbon footprint <5kg CO2/kWh without revealing exact manufacturing processes (competitive data)
- ✗Need to aggregate data from: mining → refining → cell production → pack assembly → distribution
- ✗Auditors require proof, but sharing exact numbers with competitors is not acceptable
ProofPass Implementation: 5-Day Deployment
Day 1-2: Supplier Integration
Each supplier in the chain (cobalt mine, lithium refinery, cell manufacturer) creates attestations for their stage using ProofPass API. Example: Mine creates attestation for '10 tons cobalt, origin: Congo, date: 2024-01-15'
Day 3: EuroPower Battery Production
EuroPower receives supplier attestations via QR codes on shipping containers. Scans QR → verifies authenticity → adds their own attestation: 'Battery pack produced, voltage: 400V, capacity: 75kWh, facility: Munich Plant'
Day 4: Zero-Knowledge Proof for Carbon
EuroPower needs to prove 'Carbon footprint <5kg CO2/kWh' for EU compliance, but cannot reveal exact 3.2kg number (competitive secret). Creates ZK proof: 'I know a number X where X < 5, without revealing X'
Day 5: Product Passport Generation
All attestations (mining → production → carbon proof) are aggregated into a single Product Passport. QR code printed on each battery. Customers/auditors scan QR → see full verified history.
