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)

How ProofPass Works

Turn any business event into a verifiable attestation. Build trust without revealing secrets.

1

Create Attestations

Any business event becomes a cryptographically-signed digital attestation

Examples:
  • Quality inspection passed
  • Product shipped from warehouse
  • Temperature maintained at 4°C
  • Organic certification verified
2

Prove Without Revealing

Use Zero-Knowledge Proofs to prove claims without exposing sensitive data

Examples:
  • Carbon footprint < 5kg CO2/kWh
  • Price paid within market range
  • Supplier meets labor standards
  • Product is authentic
3

Generate Digital Passports

Aggregate all attestations into a Product Passport with QR code

Examples:
  • Complete supply chain history
  • All certifications in one place
  • Immutable blockchain record
  • Instant verification
4

Anyone Can Verify

Customers, auditors, or partners verify authenticity instantly

Examples:
  • Scan QR → See full history
  • No login required
  • Works on any device
  • Compliance reports in seconds

The Challenge

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.

Specific Problems:
  • 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
The Solution

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'

Technical: Simple REST API call or dashboard form. Takes 30 seconds per batch.

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'

Technical: Verification is instant (2 seconds). Creating new attestation takes 20 seconds.

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'

Technical: ProofPass generates cryptographic proof. Auditor can verify claim is true without seeing actual data.

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.

Technical: Passport aggregates all attestations. Blockchain-anchored for immutability.
