Blockforce anchored proof of 500,000 supply chain certificates on Cardano

A Dual-Ledger Approach to Supply Chain Verification

The Cardano Foundation (@Cardano_CF) and Brazilian technology firm Blockforce have put Cardano to work as the public proof layer in an enterprise supply chain platform, with more than 500,000 records already anchored on-chain. The system is live in production, not a pilot, and is currently operating with some of Brazil's largest fashion groups.

The architecture is built around a clear separation between confidentiality and verifiability. Supply chain transactions are registered privately using Hyperledger Fabric, giving access only to approved companies and stakeholders. Sensitive commercial information, including supplier identities, contract terms, and production volumes, stays on that permissioned network. Only the cryptographic proof of those records is anchored to Cardano, where any auditor, regulator or customer can confirm a record is genuine without seeing the underlying data.

This matters because the two obvious alternatives both fall short. A fully private database protects commercial secrets but gives no outsider a way to independently verify anything. A fully public ledger provides verifiability but exposes pricing and supplier relationships to anyone watching the chain. Blockforce's setup sidesteps both problems.

Cost Engineering and the Road Ahead

Scaling a proof-anchoring system to enterprise volumes requires keeping per-record costs manageable. The partners achieved cost savings by batching certificates before anchoring them to Cardano, using Blockforce's uVerify system and configurable batching parameters to combine multiple records into fewer public transactions. The published architecture processes up to 44 certificates per transaction, with each certificate remaining individually verifiable. The Cardano Foundation and Blockforce said their engineering work reduced the public anchoring cost per record by 92%. That figure comes from the project partners and has not been independently audited.

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 supplier, fiscal, and government database records to build each traceable record before it is proofed and anchored.

The Cardano Foundation and Blockforce revealed that contracts exist to anchor up to 6.5 million certificates by 2030. Blockforce is also preparing to extend the solution to other sectors, including automobile manufacturing, agriculture, pharmaceutical production, and cosmetics.
