Cardano is now running in production as the public verification layer for an enterprise supply chain platform, with more than 500,000 records anchored, the Cardano Foundation and Brazilian technology firm Blockforce said on 31 August.
The platform is already live with Brazilian fashion groups, among them Azzas 2154, which the two companies describe as Latin America’s largest fashion group. It uses the system to trace leather across its brands.
How the Two Ledgers Split the Work
Regulated supply chains face a problem that has kept blockchain traceability stuck in pilots for years. Auditors and regulators want proof that a record is genuine. Brands do not want to publish pricing, supplier identities or contract terms in order to give it to them.
Blockforce separates the two. Detailed records for each step sit on a permissioned Hyperledger Fabric network visible only to the parties involved, structured into digital product passports aligned to GS1 standards. Only the cryptographic proof of each record is anchored to Cardano, where an auditor can confirm a record has not been altered since it was written without ever seeing what it contains.
Data reaches the system through ERP integrations, document uploads, or a WhatsApp agent built for suppliers with no digital record-keeping at all. That last route matters more than it sounds, because the lower tiers of most supply chains are exactly where documentation runs out.
The Number That Made It Viable
Cost is what kept public anchoring at pilot scale. Writing one blockchain transaction for every supply chain event becomes prohibitive once a programme moves past a handful of suppliers.
The two companies say joint engineering cut the public anchoring cost per record by 92%. The mechanism is batching. Blockforce’s uVerify component packs up to 44 certificates into a single Cardano transaction, with each certificate still independently traceable back to its own source.
That figure covers the cost of anchoring proof publicly. It is not a claim about the cost of running the wider traceability platform.
What Is Delivered and What Is Contracted
The 500,000 records are in production now. The larger number attached to the announcement is not.
Blockforce and the Cardano Foundation say signed contracts cover roughly 6.5 million certification records through 2030, with expansion planned into automotive, agribusiness, pharmaceuticals and cosmetics. That is a commercial commitment rather than delivered volume, and the distinction matters on a five-year horizon.
‘Our goal is to trace 100% of the leather across our brands by 2030,’ said Suelen Joner, head of sustainability at Azzas 2154. She said the system was built to work from the documents suppliers already produce rather than requiring them to adopt new software.
What the Announcement Does Not Show
The Cardano Foundation’s own case study on the deployment publishes no transaction identifier, no explorer link and no verification dashboard. A system whose entire selling point is that outsiders can check a record independently has not yet given outsiders anything to check. No third party has audited the claims either.
There is also a gap between enterprise use of a chain and demand for its token. At the maximum batch size the Foundation describes, 500,000 certificates would fit into fewer than 12,000 Cardano transactions. That is CNR’s own arithmetic rather than a figure either company published, and the true count will be higher because not every batch will be full. The point holds regardless: the batching that makes the economics work is the same thing that keeps the on-chain footprint small.
The Foundation frames the deployment against European rules requiring documented proof of sourcing, naming the EU Deforestation Regulation and the Corporate Sustainability Reporting Directive as the pressure driving demand. Neither company claims the platform certifies compliance with either one.
