NSAuth Overview

• One credential, endless doors – Register once and unlock physical locations, digital platforms, and community services without repeatedly proving who you are.
• Instant privilege changes – If your membership status changes (e.g., you earn a new badge or a restriction is applied), the update propagates immediately, so you never have to wait for paperwork or manual approvals.
• Privacy‑first proof of eligibility – Your personal identifiers stay hidden. You prove you belong to a trusted group without revealing your passport number, birthdate, or other sensitive data.
• Works anywhere, for anyone – Because verification relies on cryptographic signatures rather than government IDs, the system serves stateless persons, diaspora communities, and emerging micronations just as easily as residents of any country.
• No passwords to remember – Authentication uses your device’s built‑in biometric methods (fingerprint, face, PIN) or a secure hardware key, eliminating password fatigue and phishing risk.
• Self‑controlled credentials – All keys live on your device in a secure enclave. You can rotate or revoke them anytime without contacting a third party.

1. Apply with a simple proof – Submit a hashed version of your passport (or any official ID) together with a privacy‑preserving proof that you own it.
2. Community review – A trusted council evaluates the submission quickly.
3. Receive your digital membership card – Once approved, a signed entry is added to the member list and your device stores a self‑sovereign card that can be exported as a QR code for offline use.

Physical Facilities (gyms, co‑working spaces, transport)

Scan the QR code at the entrance. The reader checks the latest member list, confirms your credential, and unlocks the door—all in a split second, without ever seeing your personal ID.

Digital Platforms (online courses, media libraries, developer APIs)

Log in with your device’s biometric authenticator. The service verifies that your key appears in the current member list and grants you a session token. No passwords, no email verification, and no data leakage.

Changing or Revoking Access

If a member violates community rules, the council simply removes the key from the next version of the list. All services refresh automatically, instantly denying further access. Likewise, you can replace your key whenever you wish—just submit the new public key and the next list update takes effect without interruption.

• Multi‑signature control – Adding or removing members requires approval from a threshold of trusted operators, preventing unilateral changes.
• Public auditability – Every version of the member list is publicly readable, allowing anyone to verify who is currently authorized.
• Reasoned removals – Operators can attach a signed rationale to a removal, enabling external review while still protecting personal data.

• Gym & Sports‑Club Membership – Walk in, scan, and start your workout instantly.
• Co‑Working & Makerspaces – Access tools and workstations without separate sign‑ups; privileges can be upgraded on the fly.
• Shared Mobility (bike‑share, shuttles) – Tap your phone, ride, and the system knows you’re authorized without learning your identity.
• Online Learning – Enroll once; the platform automatically grants you course materials, labs, and alumni benefits as your badges evolve.
• Content Subscriptions – Premium media checks only that you hold a valid “subscriber” badge, never your email or payment details.
• Developer APIs & Cloud Resources – Only verified developers receive tokens, and revocation happens instantly if a key is removed.
• Community Governance & Voting – Vote securely with a proof of eligibility; votes remain anonymous while ensuring only authorized members participate.
• Financial & Token Payments – Freelancers receive token payments only after the system confirms a “contractor‑approved” badge.
• Medical & Emergency Services – Clinics verify a “medical‑access” badge without ever seeing a passport number, enabling fast care for stateless individuals.

The diagram shows how a single credential you create on your device is added to a signed, versioned member list. Every service—whether a door lock, a web app, or a voting contract—simply checks that list to confirm you have the right privileges, all without ever learning your personal identifiers.

While you won’t see the inner workings, NSAuth relies on modern web authentication (biometric passkeys), a privacy‑preserving proof system, and a globally distributed, signed member list. This combination delivers the seamless, secure, and private experience described above.
