The verification model

Built so that the evidence speaks for itself, always.

Most records of agricultural performance exist somewhere in a notebook, a spreadsheet, a conversation at a farm meeting. What they have never had is a structure that makes them permanent, comparable, and independently accountable.

Proof gives them that structure. Once a record is submitted, it is locked, not by policy, but by design. No administrator, no founder, and no contributor can edit, suppress, or remove it. The evidence is the evidence.

How a Proof Record earns its credibility

Verification isn't a single check. It builds over time.

Four layers of verification, from automated structural checks to expert review. Each layer adds credibility. Together, they create a record that stands.

01
Structural — Automated
Every record is automatically checked on submission. Are the required fields complete? Are the units correct? Is there a clear point of comparison? This happens instantly and catches the most common gaps before they enter the dataset.
02
Peer Validation
Others in the Proof community can Confirm, Challenge, or Replicate a record. These are structured actions — not comments or ratings. A Challenge must be evidenced. A Replication — where someone else records the same thing and gets the same result — is the most powerful signal in the system.
03
Reputation Weighting
Credibility is earned over time. A record from a contributor with a long, consistent track record carries more weight than a first submission. That's not gatekeeping — it's how trust works in every serious field.
04
Expert Review
The Proof Council and invited experts review records where the evidence is most significant — conflicting results, high-impact findings, or records that others are citing in decisions. Not everything. Only where it matters most.
The honest admission
Early verification will be imperfect. We're not claiming otherwise. But structured, permanent, publicly challengeable evidence, even at an early stage — is a better foundation for decisions than what has existed before.
On permanence

Once a record is submitted, it is locked — not by policy, but by design. No administrator, no founder, and no contributor can edit, suppress, or remove it. The evidence stands on its own.

What gets recorded

A Proof Record is a permanent document, not a post.

Every submission becomes a Proof Record, structured, permanent, and public. It reads like a ledger entry. It is treated like one.

Unique Record ID
Permanently assigned on submission. Format: PRF-UK-2026-000184. Locked and immutable — this record can always be cited, referenced, and found.
Core information
Enterprise, location (region by default), production stage, record type, all structured fields selected from consistent options so records stay comparable across contributors.
What was done and what it was compared against
What was applied or changed, at what rate, compared against standard practice or an untreated equivalent. Without a clear comparison, the record is marked Observational.
Measured outcomes
Numbers, with units the system enforces. Yield in t/ha. Liveweight gain in kg per head. The system does not accept 'significant improvement'.
Evidence
Geotagged, timestamped photographs. Optional lab data. Optional sensor data. What can be verified, will be.
Contributor identity
Known to Proof for verification. Publicly, you choose — contribute under your name or anonymously. Either way, the record stands.
What the status labels mean

Every record carries a status. Status only rises.

Verification builds over time as evidence accumulates. A record's status can only increase, it is never reduced except where a formal Challenge is upheld.

OBSERVATIONAL
Observational
No direct point of comparison. Useful as context and early signal, but clearly marked as lower confidence. A valid and valued starting point — especially for first submissions.
STRUCTURED
Structured
A defined comparison is in place. Measured outcomes recorded in enforced units. Comparable with other records of the same type. The baseline for a credible Proof Record.
REPLICATED
Replicated
Consistent results across multiple records from different contributors, locations, or seasons. The strongest form of evidence Proof produces without expert review.
VERIFIED
Verified
Reviewed by a peer contributor, an agronomist, or a member of the Proof Council. A Proof Score has been applied. The record carries institutional weight.
Why the language in a Proof Record is controlled

The data speaks. Nothing else does.

Promotional language is structurally excluded from Proof Records — not moderated after the fact, but made impossible by the submission process.

❌ This is not a Proof Record
"This product delivered outstanding results across every field we used it in and we would strongly recommend it to any arable farmer looking to improve margins."
✓ This is a Proof Record
Input applied at label rate, GS25. Measured outcome: +0.46 t/ha vs untreated. Soil type: medium loam. Variety: Skyscraper. Conditions: dry spring, early application.
From observation to permanent record

Designed for the field, not the office.

Proof is built around the reality of how agricultural observations are made, in the field, on the move, often in poor conditions. The submission process is designed to be completed in under two minutes.

01
Capture
Take a photograph. GPS coordinates and timestamp are recorded automatically.
~10 seconds
02
Tag
Select your enterprise, record type, and what was applied — from structured options, no typing required.

Save
No signal? The record saves locally and syncs automatically when you're back in range. Nothing is lost.

Data ownership

Your record data is yours. That is not small print — it is the model.

Contributing to Proof does not mean surrendering your data. It means giving it a permanent, structured, publicly accountable home.

You own
Your data, always.
  • Your original record data, observations, and uploaded evidence
  • The right to be identified or to contribute anonymously
  • The right to export your own data at any time
  • Credit for your contribution to the wider dataset
Proof owns
The intelligence that comes from it.
  • The verified, structured dataset as a whole
  • The verification layer — Proof Score, replication signals, status progression
  • The aggregated intelligence across the full record
  • The network — the value that comes from everything together
