The Science Behind G-Knot: Next-Generation Biometric Security for Web3

Explore Our Token

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 everything from crypto wallets to enterprise access control, enabling passwordless, spoof-proof, and seamless identity verification for the decentralized era.

Why Finger Vein Biometrics?

Unlike fingerprints or facial recognition, finger vein authentication scans the unique vascular patterns inside your finger using near-infrared light.

Impossible to Forge

Requires live blood flow, making
spoofing virtually impossible.

Resilient

Works reliably even with worn fingerprints, under dust, moisture, extreme temperatures, and direct sunlight.

Impossible to Forge

Each finger’s vein pattern is as unique as an iris, with proven separation between individuals and extremely low error rates.

Impossible to Forge

Biometric data is encrypted
and never leave your device.

The P2N2 AI Engine:
Multimodal Biometric Intelligence

At the heart of G-Knot is our proprietary P2N2 AI engine-a patented, unified 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 spoof-proof authentication.

P2N2 AI Biometric Module

Enables multimodal recognition, rapid adaptation to new threats, and future-ready expansion to iris and facial biometrics.

Tamper-Proof Secure Element

Stores encrypted biometric templates and private keys locally, never exposing them to the cloud or external networks.

Built-in Wallet App

Secure the network and earn rewards by staking GKNT as a validator or delegator.

G-Knot Blockchain

A Layer-2 ZK-Rollup chain that immutably logs biometric events and enables decentralized identity, with ultra-low fees and high throughput.

Decentralized Identity Hub (DIDH)

Anchors your biometric proof to a reusable, privacy-preserving digital identity.
