Concept

Linktree for the deepfake era. A digital identity card that cryptographically proves there is a real person behind it — not a bot, not a fake account, not an AI-generated profile.

No passwords. No email registration. One person = one account. Your passport is your login. Proof of You.

Problem

On the internet, you can't prove you're a real person.

Twitter blue check costs $8 and verifies nothing. Google reviews can be bought for $5. LinkedIn is full of fake profiles. In the era of deepfakes and AI-generated content, there is no way to cryptographically say: "this is me and I'm real."

Linktree, bio.link, link-in-bio tools — none of them solve the fundamental question: is there a real person behind that profile?

Solution

Your passport is your login. Math is your proof.

Veritas ID is a link-in-bio page where every profile is cryptographically bound to a real person. One NFC passport tap at registration. No password, no email, no personal data database.

Result: veritas.id/daniele — a public profile with links, bio, and a cryptographic IS_HUMAN status. Anyone who visits knows there is a verified human behind it. Unforgeable.

Three principles
①
One person = one account
Passport hash (SHA256 SOD signed attributes) ensures deduplication. One passport = one profile. Cryptographically impossible to create duplicates.
⓪
Zero passwords
No email registration. No password to forget. Your biometric passport is your key. NFC tap = login.
∅
Zero personal data
Server never sees name, date of birth, or passport number. Just a zero-knowledge proof — mathematical proof without revealing identity.

Tech Stack
Framework
Next.js 15
App Router, Server Components, SSR for public profiles. Optimized for SEO and fast loading.
UI
React 19 + Tailwind 4
Latest React with Tailwind CSS 4. Minimalist dark-first design. Mobile optimized.
Auth
NFC Passport → JWT
No password. Passport is the key. JWT token generated from passport_hash. Stateless authentication.
Identity
SHA256 SOD Hash
Deduplication via hash of signed passport attributes. Cryptographic uniqueness without storing PII.
Backend
FastAPI
REST API for profiles, proof verification, token management. GET /api/v1/profiles/me endpoint.
Deploy
Railway
Zero-config deployment from GitHub. SSL, DNS, environment variables. Automatic CI/CD.
