Certification
Four roles. One certificate.
The developer brings the project. The NEXUS agent computes and prepares. An independent verifier signs. The registry records.Four roles, one certificate, one signature.
02Who does what
Each role has its own responsibility.
Certification turns a project's measured results into certificates. Only the verifier signs.Only the verifier signs.
- Project developer. Brings the project and its data.The project and its data.
- NEXUS agent. Computes the impacts and prepares the evidence; it never validates.Computes and prepares, never validates.
- Independent verifier. Validates and signs; Veracity selects, engages and pays it, never the developer.Signs; paid by Veracity.
- Registry. Records each certificate, issued once and retired once.Issued once, retired once.
03What it unlocks
Weeks, not years.
Conventional certification is slow and costly. NEXUS automates it, so any project can be certified, whatever its size.
Lead timesA few days or weeks, instead of months or years.
÷10
CostsCertification within reach of projects of any size.
04Step by step
From design to retirement.
Each step leaves evidence the verifier can check.Each step leaves evidence.
- 01DesignThe developer files the project design document (PDD).
- 02Pre-checkThe agent checks completeness and eligibility.
- 03ValidationThe verifier validates the design.
- 04MonitoringMonitoring data come in; the agent computes the impacts.
- 05VerificationThe verifier checks and signs.
- 06IssuanceThe certificates are recorded in the registry.
05Seven states
The life of a certificate, fully traced.
From issuance to retirement, every state of a certificate is recorded in the registry. Retired, split and cancelled are final.Every state recorded; three are final.
- Pre-issued, optional. Before issuance, for the water module only.Optional, before issuance.
- Issued, then encumbered or transferred. Encumbered is optional and reversible: pledged as collateral.Encumbered is reversible.
- Retired, split or cancelled. Final states: a retired certificate can never be used again.Final states.
06What the verifier checks
The system, not just the numbers.
The verifier checks how the figures are produced, not only the figures.How the figures are produced.
- Calculations re-run. Deterministic calculations are checked by running them again.Re-run to check.
- AI judgements sampled. AI-assisted judgements are sampled against human review.Sampled against human review.
- More checks where it is uncertain. Control is tighter where uncertainty is high.Tighter where uncertain.

+Questions
Who pays the verifier?
Veracity selects, engages and pays the verifier. The developer never pays it directly.
What is a PDD?
The project design document: its plan, its baseline and its monitoring method.
Who validates the project design?
The independent verification body (VVB). AI pre-checks completeness and eligibility, but never validates.
Which certificate states are final?
Retired, Split and Cancelled. A retired certificate can no longer be used.
Does the AI sign anything?
No. It computes and prepares the evidence; the accredited verifier signs.
