Sustainability runs on a paradox.
We demand transparency. We require product traceability through KYP (Know Your Product). We write regulations that assume trust exists—but we build supply chains where trust is impossible to verify.
A supplier says a material is recycled. A distributor claims a certification. An authority stamps approval. And somewhere between the shipment and the signature, the data becomes an act of faith.
CircularPass just broke that cycle.
The Missing Link Was Always Identity
Blue Room Innovation launched CircularPass with a radical premise: if humans and organizations can have verifiable digital identities, why can't products?
Not metadata. Not QR codes linking to databases someone controls.
Actual cryptographic identity—where companies, suppliers, distributors, and even waste materials sign every supply chain event with zero-knowledge proofs.
The tech stack? Iden3 and Circom—the same protocol powering Billions Network's human verification system, now applied to global compliance infrastructure.
How It Works
Every actor in the supply chain gets a self-sovereign identifier (DID). When a product moves, transforms, or earns certification, that event gets digitally signed.
Zero-knowledge circuits verify the signature without exposing sensitive business data. The attestation anchors to blockchain—immutable, auditable, regulation-ready.
The result: Digital Product Passports that comply with EU ESPR standards. Traceability aligned with the UN Transparency Protocol. Credentials that authorities can verify instantly.
No middleman databases. No trust assumptions. Just cryptographic proof.
Why This Matters Beyond Recycling
CircularPass isn't just securing supply chains—it's proving the infrastructure works at institutional scale.
The same identity protocol that verifies humans can verify anything requiring trust: materials, certifications, movements, compliance records.
From Web3 to the real economy. From theory to deployment. From promises to proof.
This is what institution-ready looks like.
About Blue Room Innovation
Blue Room Innovation is a pioneering European blockchain infrastructure company building verifiable identity solutions for sustainable supply chains. Using iden3 and zero-knowledge technology, Blue Room enables companies, products, and materials to prove compliance with international standards including EU ESPR regulations and the UN Transparency Protocol. Their CircularPass platform powers digital product passports for circular economy initiatives across Europe.
About CircularPass
CircularPass is the first verifiable identity platform for sustainable supply chains, enabling companies to cryptographically sign and verify every product movement, transformation, and certification. Built on CircularTrust blockchain with iden3 protocol integration, CircularPass creates tamper-proof Digital Product Passports that meet EU ESPR compliance requirements and UN Transparency Protocol standards—transforming supply chain traceability from trust-based promises to cryptographic proof.
