From Claims to verifiable proof with the new Claims monitor

Open Food Chain is launching a new module that automatically records and verifies all origin and sustainability claims on the Cardano blockchain, turning paper-based trust into verifiable, tamper‑proof data. This release marks a step change for agrifood companies that need to prove what they promise, under growing regulatory pressure and rising expectations from retailers, auditors and consumers.

A new standard for reliable claims

The intent behind the Claims Monitor is clear: upgrade claims from static statements in PDFs and spreadsheets to dynamic data points with full traceability back to their source. Each claim about origin and sustainability, or ESG, performance is captured as a structured event, if possible third party-validated and then anchored to Cardano, including who submitted it, when and on what evidence it is based. This creates a single claims backbone that procurement, sustainability and compliance teams can trust across brands, categories and suppliers.

Why Cardano for claims

The Claims Monitor leverages Cardano’s scalable, energy‑efficient infrastructure, using the blockchain as a trusted layer for verifiable claims in food supply chains. Cardano’s deterministic extended UTXO model and low, predictable transaction fees enable claim verification to grow from pilots to large‑scale enterprise deployments while maintaining data integrity and reliable performance within the protocol’s limits.

Tangible value for brands and partners

For brands and retailers, the module turns “trust us” into “verify it yourself” by linking on‑pack QR codes or digital product passports directly to the underlying Cardano‑anchored claim records. This strengthens brand credibility, de‑risks green claims and simplifies EUDR and ESG reporting by giving teams direct access to verifiable claim histories at batch level. Supply‑chain partners benefit from clear data requirements, automated onboarding and a shared infrastructure where good performance is visible and credited across the value chain.
