🌐 Digital Identity¶

The Future of Identity — Beyond Documents¶

This section covers the emerging paradigm of digital identity — where identity moves from physical documents to cryptographic credentials, from centralized databases to decentralized wallets, and from "verify every time" to "verify once, prove everywhere."

Today: Capture document → OCR → Face match → Database verify (30-60 seconds, error-prone)

Tomorrow: Present verifiable credential → Cryptographic verification (2-5 seconds, mathematically certain)
