The Science Behind G-Knot: Next-Generation Biometric Security for Web3
G-Knot delivers the world’s most advanced authentication platform-combining patented finger vein biometrics, AI, and blockchain to set a new global standard for digital security, privacy, and user control.
Our technology powers retail crypto wallets to enterprise access control, enabling passwordless, advanced fraud security, and seamless identity verification for the decentralized era.
Unlike fingerprints or facial recognition, finger vein authentication scans the unique vascular patterns inside your finger using near-infrared light.
Liveness Detection
Built-In
Requires live blood flow, making
spoofing virtually impossible.

Engineered for Real-World Use
Works reliably even with worn fingerprints, under dust, moisture, extreme temperatures, and direct sunlight.
Precision-Matched to You
Each finger’s vein pattern is as unique as an iris, with proven separation between individuals and extremely low error rates.
Your Biometrics. Your Device.
Biometric data is encrypted
and never leaves your device.

The P2N2 AI Engine:
Multimodal Biometric Intelligence
At the heart of G-Knot is our patent-pending P2N2 AI engine—a unified, multimodal biometric intelligence algorithm that supports:
How G-Knot Technology Works
Biometric Enrollment
Local Encryption & Zero-Knowledge Proof
Decentralized Identifier (DID)
Reusable Across Ecosystem
Core Technology
Components
Patented Finger Vein Scanner
Uses near-infrared imaging to capture subdermal vascular patterns, ensuring secure biometric security.
P2N2 AI Biometric Module
Enables multimodal recognition, rapid adaptation to new threats, and future-ready expansion to iris and facial biometrics.
Biometric Security, Engineered Right
Stores encrypted biometric templates and private keys locally, never exposing them to the cloud or external networks.
