Rostervouch

Creator selection still relies on screenshots, scraped public counts and platform-specific reports that are difficult to compare or date. The supplied research confirms a live provider of creator-authorized metrics and a current portable credential standard. It found no reviewed creator-platform issuer for signed performance metrics. That is a bounded competitor finding, while several referenced platform interfaces were not verified in the supplied stage.

Rostervouch would preserve creator identity assertion, organization, platform account, connection consent, permission scope, source response, source timestamp, metric definition, metric value, audience sample, data limitation, graph-analysis method, model or rule version, suspicious-pattern finding, uncertainty, creator correction, credential schema, claim, claim period, issuer identity, signing key, issue time, expiration, signature, status endpoint, verifier request, signature-verification result, freshness result, revocation, superseding credential, brand reviewer finding, decision and deletion as distinct records.

A read-only platform connection supports provenance to an account response; it does not prove that every follower is human, valuable or controlled by the creator. Graph analysis can produce false positives and must not label individual followers or publish hidden blocklists. A valid credential signature proves that an issuer signed specific claims and that bytes were not altered; it does not prove the claims are true, current, complete or suitable for a campaign. Brand-side software may verify syntax and status but must not autonomously hire, reject, price or accuse a creator.

The pilot should use synthetic creator rosters and simulated platform responses with no real follower identities or commercial decisions. The likely buyer is a creator agency, brand partnerships team or marketplace operations owner, but supported account access, metric standardization, verifier adoption, liability allocation, review process, budget and willingness to trust a new issuer remain unverified.

A creator agency, brand-partnerships team or marketplace operations owner that needs dated, reviewable audience evidence without relying on screenshots.
