Verifiable supply‑chain credentials & compliance across every mileSupply Chain & TradeKeep supply‑chain data tamper‑proof, revocable, and instantly verifiable—whether it’s for a pallet, a batch, or a single tiny component.
Why This MattersSupply‑chain scrutiny is skyrocketing. The EU’s Ecodesign Regulation, Batteries Regulation, and the forthcoming Digital Product Passport (DPP) mandate cryptographic evidence of origin, materials, and emissions. Yet most data still travels in PDFs and emails, breaking when goods change hands.Empeiria supplies the missing trust layer: signed credentials whose hashes are anchored on the Empe Blockchain and payloads stored off‑chain (e.g. IPFS). Customs, partners, and consumers can verify facts in milliseconds—without caring whether a DID exists for every item.

Drivers for change

PDFs and spreadsheets are easy to falsify and impossible to audit at scale.
ESG and Scope 3 rules demand traceable emissions, labour, and recycling data.
Cross‑border shipments face days of delay when documentation is incomplete or untrusted.

With Empeiria, every shipment, batch, or component carries its own proof of compliance—no matter how many borders or tiers it crosses.

The Fix in 30 Seconds
number
Credential BundleA signed JSON‑LD credential ("Digital Product Passport") captures origin, ESG metrics, and compliance docs. The payload lives on IPFS (or your preferred store); its hash is anchored on‑chain.
number
QR / NFC PointerPackaging or labels carry a tiny QR/NFC tag that resolves to the credential, so even low‑value parts stay verifiable without individual on‑chain identities.
number
Instant VerificationAny stakeholder scans the code; the Empe Verifier checks the hash, signature, and revocation status in < 100 ms.

Flagship Use Case – Battery Compliance Credential
Scenario

An e‑bike maker must prove EU Battery Regulation compliance at customs.

Issue

The cell supplier packages chemistry & recycling evidence into a credential, pins it to IPFS, and anchors the hash on‑chain.

Transfer

A QR on the battery pack links to that credential; downstream partners reuse the same link—no new ID required.

Verify

Customs scans the QR; the Verifier confirms cobalt sourcing and carbon footprint within limits.

Update

At end‑of‑life, the recycler adds a new recovery credential; the QR now resolves to the full history.

Outcome

Seamless cross‑border clearance and a tamper‑proof lifecycle record.

Additional Use Cases

ESG Scorecards

Brands attach auditable emissions & labour certificates to every SKU or batch.

Recall Automation

Issuers flag defective serials; downstream systems auto‑notify distributors and customers.

IoT Sensor Proofs

Cold‑chain sensors sign temperature logs straight into the credential, blocking data tampering.

Circularity Credits

Refurbishers add a reuse credential, unlocking tax incentives and take‑back rewards.

Benefits

  • • Regulatory Fast‑PassMachine‑verifiable credentials cut border inspection times.
  • • Brand TrustShoppers scan and see real proof, reducing greenwashing backlash.
  • • Cost AvoidanceCryptographic audit trails slash fines and manual ESG paperwork.
  • • Supply‑Chain ResilienceA shared source of truth speeds partner onboarding and dispute resolution.
Technical
  • • DevelopersDrop‑in REST & SDKs (Node, Python, Go); reach a live credential flow in < 30 minutes.
  • • Security & ComplianceOn‑chain proofs with off‑chain payloads align with EU Ecodesign, ISO 59040, SEC climate rule.

Get Started

1. Define a credential schema in the dashboard.

2. Issue a compliance credential and pin it to IPFS (or your storage of choice).

3. Hit the sample API or scan the QR to watch live verification.

FAQ
Quuestion
Does every item need its own DID?
Answer
No. Empeiria works with item‑level DIDs *or* shared credential pointers. Use whichever granularity your business and cost model require.
Quuestion
How is this better than EPCIS or PDF certificates?
Answer
EPCIS shares events, not cryptographic proof. Empeiria credentials are signed, portable, and instantly verifiable—plus they can coexist with your current EPCIS feed.
Quuestion
What if a supplier’s data turns out false?
Answer
Revoke or overwrite the offending credential; downstream verifiers will reject the old proof within seconds.
Quuestion
Do partners need blockchain expertise?
Answer
No. They POST JSON to the Issuer or scan a QR. Keys and signatures are handled by the SDK.
Quuestion
How big is the QR code?
Answer
Tiny. We store only a content‑addressed hash on‑chain; payloads resolve off‑chain, so labels fit on a coin cell.
Quuestion
Can I pilot this without touching production systems?
Answer
Yes. Spin up a sandbox instance with Empe One‑Click Deployment and test against sample SKUs before integrating your ERP.
Quuestion
What about selective disclosure?
Answer
Zero‑knowledge filters (on our roadmap) will let you reveal just the compliance fact—never the full BoM.
