CIP Application Areas
CIP issues privacy-preserving (ZKP), crypto-agile (PQ-ready) timestamps and deterministic receipts. Below are representative areas where verifiable evidence improves auditability and compliance.

Role-based check-ins and care workflows with privacy-preserving receipts (no PHI revealed). Deterministic, machine-verifiable evidence for audits.
- ZKP-style selective disclosure; no sensitive payloads in receipts
- Tamper-evident timestamps for events & handoffs
- On-prem/VPC or hosted with ATO path (no authorization implied)

Buyer-assist flows with policy-bounded offers/counters. Deterministic receipts for approvals and terms to support fairness and audit.
- Fixed-shape receipts for proposals, counters, approvals
- Selective disclosure for Legal/Compliance review
- On-prem/VPC option to protect pricing strategy

Evidence for software supply chain and operational events. Receipts align with SSDF/SBOM practices and map to attestation ecosystems.
- Event receipts for build, sign, deploy, and change controls
- Crypto-agile profiles; PQ-ready roadmap
- IETF/attestation alignment (e.g., SCITT/RATS) concepts

Consistent, machine-verifiable evidence across business workflows (approvals, reconciliations, exception handling).
- Deterministic receipts enable predictable audit automation
- Canonical hashing + signatures; public verification keys
- Escrow & commercial licensing options

Receipts around critical customer interactions (consent, policy acceptance, high-risk actions) without leaking sensitive data.
- Role-scoped disclosure (only what a verifier needs)
- Tamper-evident timestamps for time-critical actions
- Works alongside existing identity & consent systems

Cryptographic lineage proofs for collaborative research. Track contribution chains and derivative works with verifiable evidence.
- Lineage receipts tie claims to signed artifacts
- Selective disclosure for peer review & impact assessment
- Non-production concept; available for private walkthroughs
