About Proof

Making evidence accessible to every farmer globally.

Proof is building permanent evidence infrastructure for agriculture — starting with biological and biostimulant trials in arable systems. The goal is simple: help farmers inspect what was tested, under what conditions, what happened, and what evidence supports it.

A Proof Record describes what was tested, what happened, and what evidence supports it. Anyone can read it. Private farm identity stays redacted.

Section IIWhy Proof exists

Most agricultural evidence is fragmented, private, and easily lost. Proof exists to change that.

Farmers make decisions in conditions of uncertainty. Agricultural products are sold with claims. Real field evidence sits in PDFs, folders, sales decks and private notebooks. Null and negative results rarely survive past the season they happened in. Conflicts are not always declared. The public has no durable shared memory of what was tested and what happened.

Proof should make it easier for farmers to inspect evidence, easier for good companies to learn what farmers actually need, and harder for weak evidence to be dressed up as certainty.

Section IIIThe mission

Proof exists to make evidence accessible to every farmer globally.

Every farmer should be able to see credible, structured evidence about what happened in real fields — not just claims in brochures, private trial decks or sales conversations. Proof is building the public evidence infrastructure for that: records that show what was tested, against what control, under what conditions, what happened, and what evidence supports it.

The first launch is arable biological and biostimulant trials. The architecture is built to expand to more crops, more systems and more regions. The long-term ambition is every farmer, everywhere.

Section IVWhat Proof is building

Permanent evidence infrastructure. Seven pieces working together.

  1. A permanent evidence ledger
    Append-only Proof Records identified by UID, locked, hashed, and citable across years.
  2. A structured record system
    Every record has a defined shape: what was tested, against what control, under what conditions, with what evidence.
  3. A contributor Workbench
    Private working environment for agronomists, farmers, researchers and trial partners to create records, manage evidence and prepare client packs.
  4. A public redacted evidence explorer
    A public surface where anyone can inspect locked records — with private farm data redacted by default.
  5. A trust model
    Six trust states earned through addenda, Evidence Queries, independent review, replication and corroboration.
  6. A private envelope
    A controlled, role-based surface for sensitive farm data, raw evidence files and contributor working notes.
  7. A commercial layer above the evidence
    Analytics, attestation, infrastructure and research partnerships — structured access to the public ledger, not control over it.

Proof records what happened in the field. It does not turn recorded outcomes into product verdicts.

Section VWho Proof serves

Farmers first. Without being anti-company.

Proof exists for farmers first. The architecture reflects that: farmers can inspect evidence freely, farm identity is private by default, and the record cannot be bought. But Proof is not anti-company — good companies should benefit from better evidence too.

  1. Farmers
    By making evidence easier to inspect. By protecting private farm data. By preserving records beyond a single season.
  2. Agronomists
    By giving field trials a permanent, structured home. By creating Client Evidence Packs. By organising evidence across farms and seasons.
  3. Researchers
    By giving on-farm evidence a structured publication route. By preserving methods, evidence and limitations alongside outcomes.
  4. Companies
    By giving better feedback from real conditions. By showing what farmers actually need. By rewarding better product development, not louder marketing.
  5. The public
    By creating a durable evidence memory for agriculture — a public record that compounds across seasons and across systems.
Section VI · The Proof Constitution

What Proof believes, what Proof will not do, and what must not change.

Three parts. The first is how Proof intends to behave. The second is what Proof will refuse to do. The third states the conditions under which Proof should be allowed to exist at all. These statements are intended to outlast the founders, the funders, and the moment.

Part I
What Proof believes
  1. 01
    Evidence should be accessible to every farmer
    Every farmer should be able to inspect credible evidence, regardless of size, geography or buying power. The first launch is narrow; the mission is global.
  2. 02
    Records should outlive the season
    Evidence should not disappear into private folders, sales decks or memory. Structured records should compound over years and across systems.
  3. 03
    Null and negative results matter
    A trustworthy evidence base cannot be built from positive outcomes alone. The record holds what was tested, not only what worked.
  4. 04
    Private farm data must be protected
    Public evidence can exist without exposing exact farm identity, raw files or sensitive commercial details. The two coexist by architecture, not by promise.
  5. 05
    Contributors should remain free
    Farmers, agronomists and researchers should be able to create, lock, view and export their own records without paying. The record layer is not for sale to the people who make it.
  6. 06
    Good companies should benefit from better evidence
    Proof is not anti-company. It is anti-weak-claim. Good companies should benefit from better evidence about what farmers actually need.
Part II
What Proof will not do
  1. 01Proof will not take money for sponsorship of Proof itself.
  2. 02Proof will not sell paid placement, product rankings, or leaderboards.
  3. 03Proof will not accept payment to suppress, hide or rewrite records.
  4. 04Proof will not accept payment to hide null or negative results.
  5. 05Proof will not run advertising on record pages.
  6. 06Proof will not sell private farm data, or expose farm identity by default.
  7. 07Proof will not turn single field outcomes into general product claims.
  8. 08Proof will not make Proof a product-promotion platform.
Important distinction

Sponsored trial work may appear as a declared conflict on a record where the trial itself was sponsored or supported. Transparency about trial funding matters. Proof itself does not sell sponsorship of records, rankings, explorer placement, or editorial influence.

Part III
What must not change
  1. Article I
    Proof should be allowed to grow, but not at the cost of the record.
  2. Article II
    The evidence layer is the part that must not be corrupted.
  3. Article III
    A public record that can be bought is not a public record.
  4. Article IV
    If a commercial opportunity conflicts with the public evidence layer, the public evidence layer wins.
  5. Article V
    If growth, speed or scale conflict with farmer trust or record integrity, farmer trust and record integrity win.
Section VIICommercial integrity

Paid above the record, not inside it.

Proof must be commercially sustainable. The business model is built to sit above the evidence layer, not inside it. Commercial customers fund the public record by paying for the tools that read across it; they do not fund it by controlling what it contains.

Commercial customers may pay for
  • Analytics on the public ledger
  • Attestation references
  • Public-record infrastructure and API access
  • Cohort analysis
  • Research partnerships
Commercial customers may not buy
  • Record suppression
  • Private farm data by default
  • Product rankings or paid visibility
  • Proof endorsement
  • Control over Evidence Queries or addenda

Section VIIIThe future Proof FoundationPlanned · future intent

Proof should succeed commercially so that it can serve the public mission more deeply.

As Proof grows, the intention is to create the Proof Foundation: a public-good vehicle funded by a portion of Proof's future profits. Its purpose would be to support the mission of making evidence accessible to every farmer globally — particularly where commercial incentives are weakest.

Possible uses, subject to proper governance and Proof's commercial success:

  • Helping farmers and agronomists in lower-resource regions access Proof
  • Funding evidence infrastructure in underserved farming systems
  • Supporting open agricultural evidence standards
  • Supporting training around field evidence and record quality
  • Preserving public-good records where commercial incentives are weak
  • Supporting public-interest research partnerships

The Proof Foundation does not exist as a legal entity today. It is stated here as future intent, requiring proper governance and Proof's commercial success before launch. No specific percentages are committed; no legal undertakings are made on this page.

Section IXLong-term vision

The success measure is not record volume. It is whether a farmer making a decision in 2030, or 2040, can find structured evidence relevant to that decision and read it for themselves.

Proof exists to make evidence accessible to every farmer globally — without turning the record into something that can be bought.
