CS8 — Education CredentialsCS8 — Education Credentials
Setting. Universities issue transcripts and diplomas requiring long‑term verification.
Design
EPs bound to institutional OKB; PQ‑hybrid cosign; 7‑year replicas with DAVS scoring; catalogs for alumni verification.
Policy Profile
CFS‑Dual; DAVS≥0.75; witnesses for registrar approval.
Workflow
- Record issuance → EP and anchors → replica receipts → catalog listing for verification.
Evidence & Verification
Offline verification remains possible decades later given proof bundles and catalogs.
Cost & Operations
BTC archival semiannual; ETH routine.
Outcomes
- Portable credentials verifiable without vendor lock‑in.
Risks & Mitigations
- Policy changes → as‑of verification; loss of bytes → multiple replicas and tombstones.
KPIs
- Verification latency ≤ 100 ms; ≥99% availability of replicas within SLA.
