ZKProva gives credit union members a portable, privacy-preserving digital identity. Verify membership, creditworthiness, and eligibility — without ever exposing personal data.
The Problem
Every loan, every account, every verification — members hand over sensitive data that gets stored, shared, and breached.
Financial services remain the #1 target for cyber attacks, exposing millions of member records.
Members expose SSN, DOB, income, address, and more — most of which lenders don't actually need.
Trust is eroding. Members want assurance that their personal data isn't being over-collected or misused.
Features
Everything your credit union needs to issue, manage, and verify member identities — without the data liability.
Members prove claims (membership, credit tier, income range) without revealing the underlying data. Powered by Groth16 ZK-SNARKs with real Ed25519 issuer signatures.
Every verification runs a rigorous pipeline: token decode, freshness check, issuer trust registry lookup, ZKP proof, revocation check, holder binding, and auto-fill mapping.
Public issuer registry with NCUA charter verification. W3C Bitstring Status List enables instant credential revocation across 131K+ slots.
Verified claims map directly to loan application fields. Lenders get "Excellent (750+)" and "$75K+" — not raw PII. Built on W3C Verifiable Credentials and DID:key.
How It Works
From registration to verification — a seamless flow that keeps member data private at every step.
Member creates a DID:key identity anchored to their credit union.
CU issues a Verifiable Credential with membership & credit attributes.
Member generates a ZK proof for a specific claim (e.g., "credit score > 700").
Proof is shared with the verifier — no PII, no raw data, just a cryptographic proof.
Lender runs 7-step pipeline: decode, freshness, issuer trust, ZKP, revocation, holder binding, auto-fill.
Technology
Built on proven cryptographic primitives trusted by the world's leading security researchers.
Security
ZKProva fundamentally changes what data leaves your credit union's walls.
Proofs reveal nothing beyond the specific claim. Not even the issuing credit union can see what's being proved.
Real Ed25519 issuer signatures on every credential. Holder binding ensures only the credential owner can present it.
Public registry of trusted credit union issuers with NCUA charter verification. Untrusted issuers are flagged instantly.
W3C Bitstring Status List enables instant credential revocation. 131,072 slots per issuer, checked on every verification.
For Credit Unions
ZKProva isn't just privacy tech — it's a member retention and growth strategy.
Give members a reason to stay. Portable identity creates a privacy benefit no bank can match — a true credit union differentiator.
Stay ahead of emerging data minimization regulations. ZKProva's architecture is built for CCPA, GDPR, and future privacy mandates.
Less data stored means less data to breach. Cut your cyber insurance costs and reduce regulatory audit exposure.
As more CUs adopt ZKProva, the shared trust network grows. Members move between CUs seamlessly — strengthening the cooperative model.
New members from partner CUs arrive pre-verified. Skip KYC friction and start serving them on day one.
Be the first credit union in your state to offer ZKP-powered identity. Position your CU as the innovation leader.
