Zero-Knowledge Proofs

Privacy-preserving verification using ZKP technology.

Overview

Zero-Knowledge Proofs allow users to prove facts about themselves without revealing the underlying data.

Use Cases

Proof Type	Proves	Hides
Balance	Sufficient funds	Exact amount
Age	Over 18/21	Birthdate
Location	Country	Address
KYC	Verified status	Personal info

How ZKP Works

Generating Proofs

// Create a balance proof
const proof = await pelago.zkp.createProof({
  type: 'balance-threshold',
  threshold: 100.00,
  currency: 'USDC',
  walletAddress: 'GXXXXX...'
});

// Verify the proof
const isValid = await pelago.zkp.verifyProof(proof);

Proof Types

Balance Threshold

Prove balance ≥ amount without revealing exact balance:

const proof = await pelago.zkp.createBalanceProof({
  threshold: 500,
  currency: 'USDC'
});

Age Verification

Prove age ≥ threshold without revealing birthdate:

const proof = await pelago.zkp.createAgeProof({
  minimumAge: 21
});

Privacy Benefits

• Data minimization: Share only what's needed
• Selective disclosure: Control what to reveal
• Unlinkability: Proofs can't be correlated
