Privacy-First Authentication
on the Midnight Blockchain
Midnight Auth combines KERI-based self-sovereign credentials with Midnight's zero-knowledge blockchain — giving your users portable, self-sovereign identity without a single byte of PII on your servers.
Two technologies. One complete platform.
Neither KERI credentials nor Midnight alone achieve trustless, portable, privacy-preserving auth. Together, they deliver something no competitor has.
KERI Credentials
Self-Sovereign Identity
Users own their credentials forever. KERI-based identifiers enable quantum-resistant key rotation and recovery — credentials survive device loss without any central data store.
- Portable ACDC credentials
- Quantum-resistant key rotation
- Zero PII on your servers
- Works offline
Midnight Network
Trustless On-Chain ZK Proofs
Verification happens on the Midnight blockchain — apps query the chain directly. You are never a trusted middleman. Apps trust cryptographic math, not your servers.
- ZK proofs on Midnight chain
- Apps verify without your server
- Immutable compliance audit trail
- Selective attribute disclosure
NIGHT & DUST
Near-Zero Verification Cost
Hold NIGHT tokens and generate DUST automatically. DUST pays for all blockchain verification transactions — turning a one-time asset purchase into unlimited verifications.
- NIGHT token generates DUST
- DUST regenerates over time
- ~$0 per verification at scale
- 97%+ platform gross margins
One asset. Near-zero marginal cost.
Midnight's dual-token model separates network value from operational cost. Hold NIGHT tokens — they automatically generate DUST, which pays for every on-chain verification. No per-transaction budget. No surprise gas spikes.
Your server is not involved at login
When a user authenticates, the ZK proof flows directly from their wallet to the Midnight chain. Apps read the result from the blockchain — not from you.
import NightProof from '@nightproof/sdk';
const auth = new NightProof({ apiKey: 'np_live_••••' });
// Generate a deep-link auth challenge
const { deepLink, sessionId } = await auth.initiateLogin();
window.open(deepLink); // opens NightProof wallet
// Wait for the user to verify (ZK proof on Midnight chain)
const session = await auth.waitForSession(sessionId);
console.log('Verified user AID:', session.sub);
// → No email. No phone. No PII. Just proof.Built for scale, compliance, and developer speed
Everything you need to ship production-grade decentralised auth without building infrastructure from scratch.
Drop-in SDK
Flutter, JavaScript, and Go SDKs. Integrate in minutes, not weeks.
Privacy by Design
Users prove credential attributes without revealing underlying data. No central identity store.
Sub-100ms Flows
KERI-based verification optimised for production-grade performance at any scale.
Real-time Analytics
Monitor auth events, success rates, and usage patterns from your developer console.
Team Management
Invite developers with role-based access controls from day one.
Multi-platform
One API. Every platform — web, iOS, Android, and server-side.
Regulatory-Ready
On-chain audit trail with GDPR-compliant design. Commitment hashes, never PII.
Trustless Architecture
At login time your server is not involved. Apps read proof results directly from the chain.
Why NightProof is different
No honeypots
We never store email, phone, or any PII. Only commitment hashes on the Midnight blockchain.
Trustless verification
Apps verify credentials directly on-chain. We cannot lie, manipulate, or go offline to break auth.
Unlimited scale economics
NIGHT token generates DUST. Once purchased, verifications cost near zero — margins grow with volume.
Simple, transparent pricing
No hidden fees. No per-user costs. Pay for what you verify.
