What is PLOOKUP

Prove facts without revealing secrets.

PLOOKUP lets your application prove that a value exists in a committed table — without revealing which value or where it appears. This is the cryptographic primitive behind private identity verification.

LOOKUP

Table-based proofs

Traditional ZK systems re-execute computations inside a circuit. PLOOKUP takes a different approach: it proves that a value belongs to a pre-committed lookup table using polynomial grand-product arguments. This makes proofs about membership, range checks, and set containment extraordinarily fast.

105 BYTES

Smallest proof in production

A complete PLOOKUP proof is 105 bytes. Compare that to FRI-based STARKs at 47KB or IPA proofs at 944 bytes. Smaller proofs mean less bandwidth, faster verification, and lower on-chain storage costs for blockchain applications.

POST-QUANTUM

Quantum-safe by construction

PLOOKUP is built on hash-based commitments and algebraic structures that resist quantum attacks. When combined with H33's Dilithium signatures and Kyber key encapsulation, you get an end-to-end post-quantum proof pipeline. No classical elliptic curve assumptions. No trusted setup ceremony. Ready for the post-quantum era today.

What You Can Prove

Private proofs for real applications.

Every proof confirms a fact about the user without revealing the underlying data. The verifier learns the answer — never the secret.

Identity

Age Verification

Prove a user is over 18, 21, or 65 without revealing their birthdate. The verifier learns “yes/no” — nothing else.

Prove: 1.70µs · Statement: age ≥ threshold

Finance

Credit Worthiness

Prove a credit score exceeds a minimum threshold without revealing the actual score. No data leaves the user's control.

Prove: 1.70µs · Statement: score ≥ 650

Compliance

Residency & Jurisdiction

Prove a user resides in an eligible jurisdiction without revealing their address. Coordinate-level precision, zero location exposure.

Prove: 1.70µs · Statement: location ∈ region

Identity

Biometric Match

Prove a biometric template matches a stored reference using Poseidon hash and cosine similarity — entirely in ZK. Template never leaves encrypted form.

Prove: 1.70µs · Statement: similarity ≥ 0.95

Healthcare

Medical Eligibility

Prove insurance status, treatment eligibility, or patient identity for HIPAA-compliant workflows. No PHI exposed to the verifier.

Prove: 1.70µs · Statement: eligible = true

Finance

KYC / AML Compliance

Prove KYC completion and sanctions clearance without passing personal data between institutions. The proof is reusable across verifiers.

Prove: 1.70µs · Statement: kyc_passed ∧ ¬sanctioned

Integration

Three lines to prove. One to verify.

plookup-example.js
JavaScript

// Generate a zero-knowledge age proof
const proof = await h33.zkp.prove({
  'statement': 'age_gte',
  'threshold': 21,
  'private_input': user.birthdate,   // never leaves client
  'public_input': Date.now()
});
// proof.size = 105 bytes | proof.time = 1.70µs

// Verify on server — no private data needed
const valid = await h33.zkp.verify(proof);
// valid = true | verify.time = 720ns

// Batch verify 64 proofs at once
const results = await h33.zkp.batchVerify(proofs);
// 64 proofs verified in 109µs

// Or use it inside full-stack auth (2.648µs total)
const auth = await h33.auth.verify({
  userId: 'user_123',
  biometric: faceData,
  // PLOOKUP proof generated automatically as part of the flow
});
