Overview
Tradespeople can prove safety and compliance training at the point of site access using verifiable credentials.
Why it matters
Mining sites operate under strict safety and compliance requirements. Manual checks slow onboarding and increase risk if records are outdated.
Ecosystem roles
- Issuer: Training providers or regulators issuing certifications.
- Holder: The tradesperson.
- Verifier: Site access control or safety compliance teams.
Operational considerations
Credentials should be time-bound with clear revocation or expiry policies to reflect ongoing training requirements.
| Objective | Enables a mining site to validate the training qualifications of a tradesperson required to work on-site |

| Dependencies | Tradesperson has training certifications already in their wallet |
