Rangers are evaluated on Effort, including kilometres walked and days actively patrolling, and Deliverables, which measure rhino sightings and the diversity of individuals observed. These trusted metrics underpin each certificate and trigger performance-based bonuses. Certificates are only issued when verified field data meets strict thresholds, ensuring real conservation outcomes and transparency.

Each certificate funds performance-based bonuses for local rhino rangers who patrol Namibia’s vast, unfenced community landscapes, home to the worlds largest free-roaming critically endangered black rhino herd. These rangers are scored on measurable conservation metrics such as sightings, diversity of individuals seen, distance walked, and days spent in the field. The incentives encourage consistent, high-quality patrol effort while directly supporting ranger livelihoods. Certificates are issued/minted only when verified data meets trusted thresholds. All information is traceable, auditable, and digitally secured via blockchain through the Wadappt platform, ensuring full transparency and accountability.
