Proof-of-Human (PoH) module
Establishes a non-transferable, human-verified identity that sits beneath Creda ID, registry entries, and downstream applications.
Proof-of-Human credential rail
The verification rail beneath regulated workforces.
Creda Protocol is a Proof-of-Human, hybrid on-chain/off-chain credential rail that turns provider identity, licenses, CME, and sanctions into live, verifiable state—powering Creda Registry, Creda ID, and ecosystem applications.
Designed for healthcare first, extensible to other regulated sectors where humans and credentials move faster than legacy systems can track.
Architecture
Hybrid on-chain/off-chain rails designed for audits.
Creda Protocol splits what needs to be globally verifiable from what must remain
private and jurisdiction-specific. Proofs and state transitions live on-chain; sensitive
metadata, documents, and logs live off-chain with strict controls.
The result: audit-ready credential state that regulators can verify, without turning PHI or sensitive provider data into public infrastructure.

- Proof-of-Human identity binding with liveness, multi-factor, and device signals.
- Credential state machines: issued, verified, expiring, expired, revoked, under review.
- Hybrid storage: verifiable proofs on-chain, encrypted metadata off-chain.
- Oracle and attestation layer for licensing boards, CME providers, and regulators.
Proof-of-Human anchor
State machines, not PDFs
Auditable by design
Credential engine
Models licenses, CME, sanctions, and other credentials as stateful objects with clear lifecycle transitions and triggers.
Oracle & attestation layer
Accepts cryptographically signed attestations from primary sources (boards, CME providers, regulators) and feeds them into the credential engine.
Ecosystem
Shared rails for registries, IDs, and applications.
Creda Protocol is not a single app. It is a common rail that powers:
- Creda Registry: national-style credential ledger for provider state.
- Creda ID: portable identity artifact bound to Proof-of-Human verification.
- Hospital, staffing, and telehealth applications: onboarding, compliance, and audit workflows built on a shared truth source.
