How To Prove What's Real

Proof ID (qHash) → Proof fingerprint Voucher → Proof receipt Verifier → Proof generator NEUS → The proof registry

No more asking "is this real?". Just check the Proof.

How Does Proof ID Work In The Real World?

A Proof ID is like a digital receipt for something you proved.

It doesn’t reveal the data. It just confirms the claim was verified — and ties it back to your wallet. Only you can reuse or access it again.

Why It Matters

• Proof without exposure: You keep your content private

• Reusable: One proof works across every chain

• Portable: Re-use it in any app, anytime

• Verifiable: Anyone can confirm a proof without needing a database

For Developers: How It Works Under the Hood

Hashing

• Function: SHAKE-256 (quantum-resistant)

• Output: Hex-encoded qHash

Signature & Ownership

• Signatures: EIP-191, EIP-1271, and EIP-6492 standards.

• Identity: Derived from did:pkh:{chain}:{wallet}

• Link: Wallet address is bound to the qHash permanently

Response Example

{
  qHash: '0xabc123...',
  verifiedVerifiers: [...],
}

Contracts & Apps Can:

• Accept qHash + signature as access proof

• Use it for token-gating, voting, or licensing

• Query the NEUS registry or local cache

---

Try It in Code

const result = await neus.verify({
  verifierIds: ['ownership-basic'],
  data: { content: "Hello world" }
});
​
console.log(result.qHash);

Standards Compatibility

• Compatible with ERC-7683 for voucher propagation

• Resolves to CAIP-10 / CAIP-19 formats

• Maps to DID metadata
