The Cardano Foundation and Brazilian technology firm Blockforce have launched a supply chain verification system in Brazil. The platform uses Cardano as its public proof layer and has already anchored cryptographic evidence for more than 500,000 commercial records.

The companies announced the deployment on Aug. 31. Major Brazilian fashion companies already use it, including Azzas 2154.
How Does the Cardano Foundation’s System Work?
This is a system built using a double-ledger approach. Blockforce tracks the supply chain transactions in a private ledger. Only the approved companies and other participants have access to this ledger.
Every supply chain transaction results in a transaction recorded in this private ledger. This transaction is then converted into a cryptographic proof and anchored to Cardano’s public blockchain.

Regulator can access the original transaction document from one of the approved parties. The submitted file is then compared to the public proof to find out if there has been any alteration to the file.
The Cardano Foundation stated that this approach would ensure that the confidentiality of the business information is maintained.
The supplier identification details, price details, and contracts are not visible on the public blockchain. But the integrity of the files can be verified by independent third parties. There is a clear limitation to this proof. It does not prove the authenticity of the original data.
Azzas 2154 Tracks Its Leather Supply Chain
Azzas 2154, dubbed as Latin America’s largest fashion group by the partners, is implementing the technology for its leather supply chain. The fashion conglomerate utilizes financial documents, suppliers’ information, and official public databases. This provides an auditable product journey.
The fashion group hopes to track all leathers used in its brands until 2030. This remains a future corporate objective. The news item did not characterize this as a current achievement.
Product regulations in Europe provide exporters one more motivation for improving documentation. Europe has launched the Ecodesign for Sustainable Products Regulation for generating Digital Product Passports. The priority sectors include textiles and clothing.
The Digital Product Passports would contain sustainability and environmental information. The Cardano Foundation and Blockforce stated that this platform could help with document verification. They did not claim that this automatically complied with any European regulation.
Batching Cuts the Cost of Anchoring Records
Creating one Cardano transaction per each event will result in higher costs when doing this in large volumes. Instead of that, the firms bundle several certificates prior to public anchoring.
According to the Cardano Foundation and Blockforce, this reduces the cost of the anchoring process per record by around 92%. Blockforce’s uVerify system provides for variable batch size. This way, several certificates will be anchored via fewer public transactions.
The announcement included neither public transaction identifiers nor a verification dashboard. It also provided no independent audit of the system’s throughput, cost, or reliability.
However, signed contracts secure 6.5 million certificates to be anchored until 2030. This figure reflects planned operations according to these contracts. It does not mean that 6.5 million records have already been anchored.
The Cardano Foundation claims that the confirmed production volume is above 500,000 certificates. In addition to fashion, Blockforce plans to deploy the technology in other industries. Among them are auto manufacturing, agricultural business, pharmaceuticals, and cosmetics.
