Proof of Forest

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

Powered by Digital Tree Identity™

We give a standing tree an immediate value for the people who live beside it — no logging, no carbon certificates. A permanent incentive to keep Africa’s wildlife corridors standing.

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.

This project creates a second source of income — without changing traditional livelihoods.

Not conservation versus people — conservation plus income.

“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 Baseline

    Millions of crowns detected once. Then the AI steps back.

  3. 03

    Digital Tree Identity

    Each tree becomes a permanent, verifiable record.

  4. 04

    Random Selection

    Each quarter, unpredictable reference trees.

  5. 05

    Community Validation

    A neighbour walks to the tree and photographs it.

  6. 06

    Blockchain Verification

    Tamper-proof, transparent, auditable.

  7. 07

    Smart Contract

    The reward is calculated automatically, by difficulty.

  8. 08

    Reward

    Value lands directly in a local wallet.

Community app

Four taps. No words.

This is the real Porini Trees field app — not a concept. Every screen here is the live interface citizens already use: find the tree, verify it, get paid.

  • Go to tree
    GPS guides to the exact reference tree.
  • Take photo
    One crown, framed by the app.
  • Send
    Queued offline, synced automatically.
  • Reward received
    Token lands in the local wallet.
The real field app — built on the same stack as our live Porini Trees MVP.

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.

Confidence

You don’t measure every tree to know the forest. 1,000 random trees represent five million — at 95% statistical confidence.

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.

Why blockchain at all

From a single tree to a protected corridor.

Digital Corridor Identity

The blockchain does not store the tree. It stores its verifiable life story — and binds thousands of them into one Digital Corridor Identity.

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.

Single tree
≈ 1 USD
Remote tree
≈ 2 USD
Cluster of 5
≈ 5 USD
Rewards are issued as blockchain tokens and can be redeemed locally. (1 USD ≈ 20 NAD.)

Built on a fee-light, ESG-credible chain (e.g. Hedera) — sub-cent micro-payments with an auditable trail, not 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.

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

Every reward flows from a verified tree straight into the local economy — not to Binance, not to Coinbase, not to Visa.

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.

Target pilot budget
≈ CHF 100,000

Jointly funded by WWF and Porini Foundation.

Contribution by Porini Foundation

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

Project architecture & scientific design
AI-assisted baseline mapping

Project management & technical documentation

Porini Foundation contributes substantial in-kind development and technical expertise, reducing external funding requirements.

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

We are not monitoring trees. We are building a new conservation economy around wildlife 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.
