The Cardano Foundation and Brazilian technology firm Blockforce announced some big news. ADA is now live as the public proof layer inside Blockforce’s enterprise supply-chain traceability platform. The system is already running with Brazil’s largest fashion groups and has anchored more than 500,000 supply-chain records.
The structural problem this solves is straightforward. Regulated supply chains need outside parties to confirm a record is genuine without handing over the commercial data behind it. A fully private database gives brands no way to prove anything to an outsider. A fully public ledger proves everything but exposes pricing, supplier identities, and contract terms to anyone watching the chain.

Blockforce’s answer keeps detailed records for each supply-chain step on a permissioned network, visible only to the parties directly involved. Only the cryptographic proof of those records gets anchored to Cardano, where any auditor, regulator, or customer can confirm a record’s integrity without ever touching the underlying data.
Cost is what kept this model stuck at the pilot stage. Anchoring hundreds of thousands of individual records publicly was never economically viable at enterprise transaction volume, which is precisely the scale regulated traceability requires once a program moves past a handful of pilot suppliers.

How Blockforce’s Dual-Ledger Proof Layer Works in This Cardano News
Joint engineering between the two organizations cut the cost per record by 92%, which is the figure both sides point to as the unlock that moved public verification out of proof-of-concept territory and into production at real volume. More than 500,000 records are already anchored under that model.
Supplementary technical material from Blockforce describes the permissioned side of the architecture as running on Hyperledger Fabric, with additional storage components referenced alongside it.
The full architecture, including the uVerify component and the specific batching parameters used to group certificates into Cardano transactions, is laid out in the Cardano Foundation’s Blockforce case study.
Guilherme Pereira, Ecosystem Growth Specialist LATAM at the Cardano Foundation, framed the milestone in infrastructure terms rather than novelty terms:
“The milestone for me is seeing blockchain fit naturally into enterprise infrastructure, delivering the verifiability, traceability, and scale that companies need. Supply chain records are written today and questioned years later, and a public network is what keeps that proof intact for the full product life cycle.”

Compliance and Traceability Implications
The announcement itself does not certify compliance with any specific regulatory regime by name. It frames the model around giving auditors and regulators independent verification capability, not a compliance stamp.
Broader references to EU sourcing rules circulating in trade coverage should be treated as market context rather than claims made by the Cardano Foundation or Blockforce directly.
Suelen Joner, head of sustainability at Azzas 2154, described the practical goal driving adoption:
“Our goal is to trace 100% of the leather across our brands by 2030. To get there, we built a solution with Blockforce that works with the reality of the chain and uses the data suppliers already produce. Rather than asking them to adopt new systems, we start from that information and turn it into a single auditable record.”
Beyond fashion, the two organizations say expansion is planned into automotive, agribusiness, pharmaceuticals, and cosmetics, using the same dual-ledger structure.
