Frequently Asked Questions

What is the Founders Edition of the G-Knot wallet?

The Founders Edition is a limited-supply launch of the world's first finger vein biometric crypto wallet, designed for early adopters. It features advanced live-tissue authentication to prevent spoofing, cold storage with PIN + MFA, and seamless integration with the $GKNT token ecosystem for governance and perks. Only 10,000 units are available, making it an exclusive opportunity to own cutting-edge security tech at a presale discount.

How does G-Knot’s finger vein biometric technology work, and why is it so secure?

G-Knot uses finger vein biometric technology, which identifies individuals by the unique vein patterns inside their fingers. Near-infrared light passes through the finger to illuminate the veins, which contain deoxygenated hemoglobin. A CCD sensor captures this internal vein structure through an optical filter, producing a detailed and naturally hidden biometric pattern.

The image is processed by our patented P2N2 AI system (Pattern-to-Network-to-Pattern Neural Engine). This engine performs advanced steps such as noise removal, finger isolation, curvature-based vein extraction, binarization, and thinning to create a secure encrypted biometric template. Liveness detection requires active blood flow, preventing spoofing with photos, casts, or replicas.

All biometric data stays fully local on the device and is verified through zero-knowledge proofs, never uploaded or sent to any server. The system supports up to eight enrolled fingers (24 total patterns), with AI that can adapt to natural variances or minor injuries over time.

Because authentication uses encrypted templates, hardware-level liveness checks, and on-device matching, G-Knot delivers high accuracy, strong spoof resistance, and secure, password-free access without relying on recovery phrases.

What are the key value propositions of using finger vein technology in the G-Knot wallet?

The technology offers unparalleled security through anti-spoofing and encrypted, on-device storage of biometric templates, preventing external access or tampering. It enables convenient, password-free wallet setup and recovery without mnemonic phrases—using finger vein data as an encryption key for seed generation. Other benefits include fast authentication (under 1 second), integration with MFA for layered protection, and durability against physical wear. In the G-Knot ecosystem, it powers secure crypto transactions, access control, and future multi-modal systems for even higher accuracy.

Why is G-Knot’s liveness detection more secure than fingerprints or facial recognition, and what makes it highly spoof-resistant?

G-Knot’s biometric system uses advanced liveness detection to ensure that only a real, living finger can authenticate. The sensor shines dynamically modulated near-infrared (NIR) light into the finger, allowing it to detect the movement of deoxygenated hemoglobin within the veins. These real-time optical changes confirm that the finger is alive and actively circulating blood.

This internal-liveness check prevents spoofing with photos, silicone casts, 3D masks, prosthetics, or high-resolution replicas. Unlike fingerprints or facial recognition, which rely on external features that can be copied, lifted, or imitated, finger vein patterns are internal, invisible, and impossible to reproduce without medical-grade imaging.

Vein patterns also remain stable over a lifetime and are unaffected by surface conditions like cuts, dirt, moisture, aging, or cosmetic changes, resulting in long-term reliability. Because the biometric pattern is internal and hidden, it cannot be captured or forged from a surface touch or image.

G-Knot enhances this security with on-device encrypted storage, zero-knowledge proof verification, and hardware-level protection, creating a multi-factor authentication process that is inherently more secure and spoof-resistant than fingerprints or facial recognition systems.

Why is the G-Knot hardware wallet considered secure?

Because it is built on the PentaShield architecture, which reinforces five layers simultaneously - hardware (SE), app, server, device-to-app (BLE), and app-to-server (TLS). Even if one layer is compromised, the others are designed to block the attack and maintain security.

What are the benefits of an EAL6+ Secure Element (SE)?

The SE ensures that keys never leave the chip, and all sensitive operations are processed internally. Biometric templates and critical data are stored in encrypted form, providing strong resistance against both physical and software-based attacks.

If I lose the device or injure a finger, how do I recover access without being locked out?

If you lose your G-Knot device or injure a finger, recovery is designed to be secure yet user-friendly, ensuring you're not permanently locked out. Our system supports multi-finger enrollment (up to eight fingers), so you can register additional fingers in advance or share access with trusted individuals like a spouse or partner if desired. Vein patterns remain stable and unaffected by minor injuries, providing built-in redundancy. For device loss without shared access, use the encrypted QR backup you created during setup. On a new device, scan the QR code and enter your personal PIN to initiate decryption. You'll then confirm your identity by re-registering your biometrics (finger vein scan), which is verified via zero-knowledge proofs (ZKP) for privacy—proving authenticity without exposing raw data. This restores your wallet seamlessly, with all processing on-device to maintain security.

Is it really convenient without cables since it’s mobile-first?

Yes. With BLE connectivity, signing and transactions work seamlessly on both iOS and Android without any cables. Device pairing is guided step by step through the app interface, allowing users to clearly follow the process on-screen.

What if the app is deleted or the smartphone is replaced?

Even if the app is reinstalled (due to deletion or phone change), the same wallet address is restored simply by reconnecting with the existing device. No additional recovery steps are required as long as the registered device is available.
