# Getting started as a verifier

Verifier Hub is the dedicated workspace for accredited third-party verifiers to conduct structured carbon verification engagements with client organisations directly within CarbonSig. It provides a governed, audit-ready environment aligned with ISO 14064-3, ISO 14067, GHG Protocol, and other requirements.

**Sending revisions:** During an active engagement, verifiers raise findings for any issue that requires client attention — whether a missing evidence document, a calculation discrepancy, or a methodology gap. Clients receive a notification and must respond to each open finding before the round can advance. The process is iterative: multiple review rounds may occur until the verifier is satisfied and issues a verification opinion. Snapshots of the registered system are locked at each round boundary, preserving an immutable audit trail.
