Proof of Forest

A community-based Digital Tree Identity system for wildlife-corridor monitoring

We pay the people who live beside the forest to monitor it — verified by satellite, by science, and by a transparent reward they can spend at home.

Why

Corridors disappear — not because people are bad, but because families need food.

Clearing is a consequence of missing alternatives. So this project does not pay people for conservation. It pays them for monitoring — honest, verifiable, and rewarded the moment the work is done.

“The trees are not the point. They are the statistical reference points for something larger — a functioning wildlife corridor.”

Core innovation

From one satellite pass to a living local economy.

  1. 01

    Satellite

    One high-resolution baseline capture.

  2. 02

    AI detects every tree

    Millions of crowns, located once.

  3. 03

    Digital Tree Identity

    Each tree becomes a verifiable record.

  4. 04

    Random statistical sampling

    The forest, represented — at a fraction of the cost.

  5. 05

    Local community

    Paid to monitor, not to conserve.

  6. 06

    Photo verification

    One tree, one photo, from the field.

  7. 07

    Blockchain verification

    Tamper-proof, transparent, auditable.

  8. 08

    Automatic reward

    No paperwork, no middlemen.

  9. 09

    Local wallet

    Value lands directly with the citizen.

  10. 10

    Local economy

    Spent in the village — money stays home.

The core · once

Every tree earns a digital identity.

AI maps the forest once, in high resolution. After that, the AI is barely needed. What remains is a permanent record for each tree — like a digital passport — and the blockchain stores its history, not the tree. A life story, tree by tree.

Thousands of these identities compose a Digital Corridor Identity — the real subject of protection.

The science

Random sampling, every quarter.

Each quarter the system picks reference trees at random — 400, 800, 3,000. Nobody knows in advance which. Because they are random, they represent the whole forest. This is the scientific heart of the method.

Different corridors, different intensity. It saves an extraordinary amount of money — without losing scientific weight.

No text · no forms · works offline

Community app

Four taps. No words.

Go to the tree. Take the photo. Send. Receive the reward. Only icons, no forms, no literacy barrier. It works offline and synchronises the moment a signal appears.

  • Go to tree

Blockchain

Not crypto. A transparent community incentive layer.

On successful validation, the wallet automatically receives a token — for example 1 USD ≈ 20 NAD. The amount is variable: the harder the task, the higher the reward.

Special mission

Built on a fee-light, ESG-credible chain (e.g. Hedera) — micro-payments at sub-cent cost, with an auditable trail rather than speculation.
Smart reward system

Not every tree costs the same. The system knows.

From distance, density, terrain and season, the reward is calculated automatically — fair to the citizen, efficient for the project.

Community economy

Tokens are redeemed locally — the money stays in the village.

Scientific value. This is not a replacement for classical monitoring — it is a statistically validated sampling system that cuts cost dramatically without materially losing rigour.

Milestones

Five funded phases.

  1. 1
    Phase 1

    Baseline

    AI maps every tree once. Each receives a Digital Tree Identity.

  2. 2
    Phase 2

    Blockchain infrastructure

    The transparent incentive layer: wallets, rewards, audit trail.

  3. 3
    Phase 3

    Community app

    Offline, icon-only, built for the field.

  4. 4
    Phase 4

    Pilot deployment

    First corridors monitored by their own communities.

  5. 5
    Phase 5

    Evaluation

    Statistical validation, lessons, and the path to scale.

Funding per phase is set with the partner — the WWF enters figures to its own budget capacity.

Contribution by Porini Foundation

Not only funding — a substantial part built as our own contribution.

Project architecture & scientific design
AI-assisted baseline mapping
Monitoring platform development
Blockchain infrastructure & smart contracts
Mobile app (offline-first, icon-based)
Dashboard & reporting
Project management & technical documentation

As a result, the bulk of external funding flows into local implementation, community engagement and fieldwork.

We are not monitoring trees.
We are protecting corridors.

The trees are the reference points. The Digital Tree Identity is the building block of a Digital Corridor Identity — community-owned, scientifically validated, and cheap enough to last.
