Making supply chain claims publicly verifiable

Pairing Hyperledger Fabric with Cardano to keep enterprise-scale traceability both private and auditable

[object Object]
Blockchain introduces new possibilities for supply chain transparency, but proving compliance requires more than a record that simply exists.
Auditors and regulators need proof, not a brand's word, on where materials came from, who made them, and their carbon footprint. Undisclosed sourcing is treated as worst-case.

Most supply chains span tiers no brand has directly audited, and lower-tier suppliers often lack the digital systems to produce a structured record. Private databases keep sensitive data safe but leave nothing for outsiders to validate. Fully public ledgers solve that visibility problem but expose commercial terms, pricing, and supplier relationships to anyone watching the chain.

Solution

Blockforce built its supply chain platform on a dual-ledger architecture designed to secure private data while delivering verifiable proof

Commercially sensitive records, supplier identities, contract terms, and production volumes are captured and stored on a permissioned Hyperledger Fabric network, visible only to the parties who need them. Verifiable proof of those records is then publicly anchored on Cardano through a batching process, condensing up to 44 supply chain certificates into a single transaction, while each remains independently traceable to its source.

Cardano gives Blockforce a public trust layer built for enterprise scale.

Structured, verifiable proof for enterprise supply chains

Combining a permissioned ledger with public anchoring enables a clear, auditable process for supply chain verification.

Data capture

01.

Supply chain data is captured through ERP integrations, document uploads, or a WhatsApp AI agent built for suppliers without digital systems.

Record structuring

02.

Records are structured into digital product passports (DPPs) and stored on Blockforce's permissioned Hyperledger Fabric network.

Batch anchoring

03.

The batching process packs up to 44 certificates into a single batch and anchors verifiable proof for each on Cardano.

Independent verification

04.

Auditors, regulators, and brands can independently confirm any record's authenticity on Cardano without accessing the underlying private data.

Results

The implementation establishes a basis for provable, auditable supply chains at enterprise scale.

01.
500,000 certificates anchored
The initial production migration grouped records into batches, condensing what would otherwise require hundreds of thousands of individual transactions
02.
Batching built for enterprise scale
Blockforce batches up to 44 certificates per transaction. This use-case-specific architecture makes anchoring commercially viable at enterprise scale.
03.
Compliance built into the platform
GS1-aligned digital product passports and dedicated regulatory modules give brands a documented, audit-ready trail without a separate manual process.
04.
Sensitive data stays confidential
Supplier identities, contract terms, and production details never leave Blockforce's permissioned network; only their cryptographic proofs reach the public chain.
05.
Built to scale across industries
With roughly 6.5 million certification anchors contracted by 2030, the same infrastructure is being prepared for automotive, food and beverage, and cosmetics.

"We needed a public infrastructure layer that could handle enterprise transaction volume without enterprise transaction costs. Working with Cardano gave us that: a way to batch dozens of certificates into a single anchor, immutable and independently verifiable, at a cost structure that actually works at scale."
