Built for food supply chains

One simple promise: same data, same formula, same price, same proof.

Calculable

The price comes from a public, versioned formula — not a black box.

Verifiable

Each calculation produces an integrity hash enabling independent verification.

Defensible

The audit preserves the formula, registry version, sources and result to replay the calculation.

Useful for food chains

OpenValue connects field constraints, lot quality and commodity volatility to support more stable pricing decisions in the food chain.

How OpenValue works

From field signal to shared proof.

01
Market reference (P0)
A price base is selected via sources declared in the registry (e.g. cereal, coffee, cocoa references).
02
Normalized indices (Ii)
Climate, social, logistics, supply/demand, quality, risk — with direct impact on agricultural supply chains.
03
Weighting + interactions (wi, γij)
The formula applies explicit weights and documented interactions.
04
Monetary adjustments (A*)
Local costs (distance, energy, etc.) are added transparently.
05
Result + hash
The engine returns a price, a formula version and a cryptographic proof.

Why now?

The food chain needs a shared pricing language.

Rising commodity volatility: more fragile contractual decisions.
Margin pressure on producers and processors.
Growing demand for transparency from auditors, funders and buyers.
Need to better value the actual quality of agricultural lots.

OpenValue provides a common calculation and verification base to move beyond purely relational negotiations and reduce disputes.

Technical trust + institutional trust.

Technical transparency

Explicit, stable v1 formula. Strict input validation (required indices, weights, consistency). Standardized output: price, hash, version, timestamp.

Native auditability

Immediate hash verification after calculation. Audit envelope including formula version, registry version and source versions. Replay capability for internal control or external auditor.

Registry & data quality

Versioned registry with validation schema. Index-to-primary-source and fallback mapping. Data freshness policy and stale grace management.

Foundation governance

Open standard governed by clear rules. Neutrality toward market participants. Priority on traceability, reproducibility and interoperability.

Food chain trust

Same method between producers, cooperatives, traders and processors. Better readability of price differences linked to quality and risk. Common base for commercial discussion and quality control.

The OpenValue Foundation: securing the standard, federating the ecosystem.

The foundation carries the mission of fair and verifiable pricing. It maintains the standard, structures the evolution governance and facilitates adoption across the entire ecosystem: producers, cooperatives, buyers, platforms, integrators, auditors and researchers.

Mission

Make price formation readable, reproducible and auditable.

Governance

Evolve the standard through an open, versioned process.

Ecosystem

Support partners, technical contributors and data providers.

Trust

Promote verifiable practices in service of sustainable exchanges.

Who is it for?

Built for actors who can no longer negotiate blind.

	Producers and cooperatives	Better defend the value of quality (protein, moisture, impurities, etc.) and reduce price disputes.
	Buyers and processors	Industrialize a defensible and consistent pricing logic between partners.
	Platforms and integrators	Integrate a verifiable pricing engine without rebuilding an entire cryptographic stack.
	Audit and compliance	Quickly verify how a price was calculated, with exploitable proofs.
	Food industry players	Align raw material purchases, quality constraints and traceability requirements with a single calculation method.

Priority supply chains

A standard spanning major agricultural commodities.

Cereals and oilseeds

Wheat, corn, barley, rapeseed, sunflower: volatility, lot quality and logistics costs.

Tropical commodities

Coffee, cocoa, sugar: climate exposure, risk and international fluctuations.

Oils and base ingredients

Vegetable oils and agricultural ingredients with high processing cost impact.

Animal nutrition and mixed chains

Raw materials indirectly influencing food costs via upstream supply.

Frequently asked questions

Clear answers about the OpenValue model, technical integration and foundation governance.

What is OpenValue?

OpenValue is an open standard for fair price calculation. It transforms versioned data and an explicit formula into a verifiable price.

How is OpenValue different from a simple pricing spreadsheet?

OpenValue adds technical reproducibility (deterministic engine), cryptographic verification and a complete audit structure.

Is it a blockchain?

No. The core calculation is a deterministic engine. Trust comes from reproducibility, the integrity hash and the audit trace.

Which hash algorithm is used to verify a calculation?

The calculation result is verified with a hash in the format blake3:[digest].

Can OpenValue be integrated into an existing stack?

Yes. The project exposes a @openvaluefoundation/core package and an Adonis integration @openvaluefoundation/adonis.

What data signals are taken into account?

The v1 formula combines a reference price (P0), normalized indices (climate, social, logistics, supply/demand, quality, risk), interactions and additive adjustments.

How is data quality managed?

A versioned registry maps indices to primary/fallback sources, with freshness management and caching.

Which commodities are targeted first?

The foundation is designed for the major agricultural food chains: cereals, coffee, cocoa, sugar, oils and other commodities based on pilot programs.

Does OpenValue replace commercial negotiation?

No. OpenValue provides a defensible, shareable calculation base. Negotiation remains possible, but is better informed and more transparent.

How is lot quality taken into account?

Through quality indices integrated into the calculation, with a versioned and auditable logic that makes premiums and discounts explicit.

Is the project open source?

The repository displays an MIT framework with mention of a specific commercial license. Check the exact license terms for your use case.

What is the role of the foundation?

To ensure governance neutrality, maintain the standard, federate the ecosystem and guarantee continuity of verification practices.

Can OpenValue serve food sovereignty?

Indirectly yes: by improving price readability and trust between actors, OpenValue helps stabilize purchasing, sales and contracting decisions in supply chains.

Why is SHA-256 also mentioned?

The project also uses SHA-256 checksums for registry artifacts (publishing/verifying files), which is distinct from the calculation result hash.
