Nautilus Infra

The Age Verification MVP is powered by a dual-backend system, combining the strengths of Python and Rust for optimal performance and security.

Nautilus Infra

Python Backend

• Role: Handles core verification logic.

• Capabilities:

  • OCR for extracting ID data.

  • Facial liveness and matching for identity confirmation.

  • OTP generation and validation.

• Output: Produces a JSON payload with verification details, sent to Kafka:

  {
    "user_wallet": "0x123abc...",
    "did_id": "age_18_plus",
    "result": "verified",
    "evidence_hash": "sha256:3f2a...9e4b",
    "verified_at": "2025-09-24T12:31:00Z"
  }

Rust Backend

• Role: Manages blockchain integration.

• Capabilities:

  • Consumes Kafka messages.

  • Signs payloads with Nautilus and ODA ephemeral keys.

  • Updates the smart contract to record verified users.

Why It Works

The Python backend ensures fast, reliable verification, while Rust adds secure, tamper-proof blockchain updates. Together, they create a powerful and trustworthy system.
