Cardano anchors over 500,000 Brazilian supply chain records, 6.5 million planned by 2030

Double-ledger approach and privacy measures

The solution employs a double-ledger architecture. Supply chain transactions are registered privately using Hyperledger Fabric, giving access only to approved companies and stakeholders. Each transaction is then converted into a cryptographic proof and stored on the Cardano blockchain as a public anchor point.

Regulators can review original supply chain documents from authorized parties and compare them with the corresponding cryptographic proof on Cardano. This process helps confirm that documents remain unaltered, strengthening the trustworthiness of supply chain data.

The Cardano Foundation stated that this method keeps sensitive business information confidential. Supplier identities, contract terms, and price details remain protected and are not recorded in the public domain, while third parties can still verify the integrity of data. However, public proofs do not guarantee the authenticity of underlying documents; they merely confirm that data has not been modified since anchoring.

Fashion industry adoption and future outlook

Azzas 2154, described by its partners as Latin America’s largest fashion group, was among the first to implement this technology in its leather supply chain. The company uses the platform to track financial documents and supplier data using information from public databases, aiming to audit the journey of leather products across its brands by 2030.

The Cardano Foundation and Blockforce revealed that contracts exist to anchor up to 6.5 million certificates by 2030. This number reflects planned commitments rather than current achievements. As of now, more than 500,000 records have been anchored using the system.

Blockforce is preparing to extend the solution to other sectors, including automobile manufacturing, agriculture, pharmaceutical production, and cosmetics, reflecting ambitions for broader supply chain transparency.

Cost efficiency and adaptation to regulation

To control costs in scaling up, Blockforce and the Cardano Foundation are bundling multiple certificates together before anchoring them publicly. This batching strategy reportedly cuts the cost per record by approximately 92 percent, as opposed to creating individual blockchain transactions for each supply chain event. Blockforce’s uVerify system allows partners to adjust the batch size depending on operational needs.

Suppliers, prices, and confidential contracts never leave the private network, yet a cryptographic fingerprint for each transaction is securely anchored on Cardano for independent verification, ensuring data integrity without exposing sensitive company details.

European regulations, including the recently launched Ecodesign for Sustainable Products Regulation, are accelerating the adoption of Digital Product Passports for sectors like textiles and apparel. These passports are intended to include detailed environmental and sustainability information. While the Cardano-Blockforce platform could support document verification, the joint statement clarified that the system is not automatically compliant with any specific European mandates.

No public transaction identifiers or audit dashboards were shared during the announcement. Additionally, there has been no external evaluation of the platform’s cost or performance to date.
