3.2 Technical architecture system
3.2.1 Hardware layer: encrypted security environment and data collection terminal
(1) Core hardware configuration
AI computing center:
The Dimensity 8200 octa-core processor (4nm process, 1 3.1GHz Cortex-A78 large core, 3 3.0GHz Cortex-A78 large cores, and 4 2.0GHz Cortex-A55 small cores) optimizes neural network computing performance through instruction-level dynamic scheduling. Its integrated fifth-generation APU 580 supports INT8/INT16 mixed precision operations, and its AI computing power is about 8TOPS. With UFS 3.1 storage and LPDDR5X memory, the system can process multiple AI tasks in parallel (such as real-time transaction signature verification and multi-chain wallet status synchronization), and ensure the independence and stability of key tasks through memory domain isolation technology.
Multi-camera spatial modeling system
The 100-megapixel rear main camera (OIS optical image stabilization) and the 32-megapixel front camera form a multi-line stereo vision system. Through the deep learning parallax estimation algorithm, sub-centimeter depth perception is achieved within the range of 0.5-4 meters. Innovative fusion of IMU inertial measurement unit data (sampling rate 1000Hz) dynamically compensates for the impact of hand-held jitter on spatial modeling. In DeFi application scenarios, the system can provide stable spatial anchoring capabilities for AR asset displays in physical stores.
Quantum security engine
The under-screen optical fingerprint module adopts multi-spectral biometric technology:
① Liveness detection: 780nm short-wave infrared light penetrates the epidermis to collect the capillary topology of the dermis (rejects silicone fingerprint film attacks).
② Encrypted link: The fingerprint feature generates a 320-bit quantum-resistant hash value through the national secret SM3 algorithm and stores it in the physical detection-proof memory of the TEE security zone (PUF technology realizes the binding of keys and chips).
③ Performance indicators: The unlocking speed in dry and wet finger scenarios is 0.28 seconds, FAR (false acceptance rate) <0.002%, and supports 100,000 consecutive authentications without attenuation. Trusted Execution Environment (GlobalPlatform Certified TEE)
In the three-layer protection system built by ARM TrustZone, the Cosmic Cipher series of products supports closed-loop protection from key generation to destruction at the hardware level:
① Secure generation: Integrates a true random number generator that complies with the NIST SP 800-90C standard, with an entropy value of ≥0.97 per bit.
② Hardware binding: The private key is stored in the OTP storage area of the eSE security chip and is bound to the physical fingerprint of the processor (to prevent transplant attacks).
③ Policy execution: Each key is associated with a double factor of application hash value + fingerprint feature, for example, the BTC wallet key only responds to Bitcoin Core client calls that have passed the signature verification.
Transaction acceleration engine
The Cosmic Cipher series of products supports optimization of blockchain operations through heterogeneous computing architecture (can be optimized through hot update system): a.CPU acceleration: The Dimensity 8200 processor has a main frequency of 3.35GHz, supports a dedicated encryption pipeline, and the secp256r1 curve signature speed can reach 412 times/second (19% increase over the previous generation). b.Storage optimization: Supports UFS 3.1 storage, enables Turbo Write technology, and the mnemonic encryption backup rate is increased to 1.2GB/s (full disk erase takes <2.8 seconds). c.Network collaboration: 5G baseband integrates IPSec hardware acceleration, and block broadcast delay is reduced to 18ms (73% increase compared to LTE environment).

3.2.2 Visual layer: 3D creation kit - 3D light field display native content engine
On the visual level, Cosmic Ciphe uses advanced light field display technology to achieve the following on a 6.95-inch AMOLED screen:
Dynamic parallax compensation:
The innovation of light field display technology lies in its adaptive optical properties. Each square centimeter contains 1,200 independently controlled cylindrical lenses. When the built-in gyroscope detects the movement of the user's head, the FPGA controller will recalculate the lens curvature within 3ms so that the screen pixel light is accurately directed to the pupils of both eyes. With a 120Hz refresh rate, a dizziness-free stereoscopic visual experience is achieved. In the game scene, when the player observes sideways, the system automatically adjusts the depth of field parameters to keep the spatial position of the virtual object stable.
Multi-format adaptation:
For 3D content from different sources, the display system has built-in dedicated decoding chips: for left-right format videos of movies and TV shows, the frame rate is increased to native 120fps through AI interpolation technology; for professionally produced 2D+Z depth map formats, the depth information is used to reconstruct the stereoscopic parallax field; the most innovative is the automatic recognition function of multi-grid formats - when it is detected that the picture is divided into 9 grids, the system will extract the parallax parameters of each block and dynamically synthesize a 360-degree panoramic effect. These conversion processes are all completed in the display driver chip to ensure that the picture delay is lower than the threshold of human visual perception.
Eye comfort mode:
On the basis of traditional blue light filtering, the system tracks the user's pupil contraction status in real time through the front camera. When it detects that the user has been staring at the screen for more than 20 minutes, it will automatically start a composite protection strategy: first adjust the refractive index of the liquid crystal lens to shift the focus from the screen plane to a virtual distance of 1 meter; at the same time, dynamically filter the 415-455nm band blue light and adjust the color temperature to a warm 5500K. Clinical tests have shown that this technology can reduce the visual fatigue index by 62%.
At the same time, by taking advantage of this hardware feature, a full-link solution of "creation-optimization-presentation" was built to reshape the mobile terminal 3D content display scene through three major scenarios:

（1）Web3 task incentive system
The Web3 task system is a major innovation in the Mind Mosaic Identity ecosystem. By providing a rich task selection and reward mechanism, it not only promotes the growth of the community and the marketing promotion activities of Web3, but also brings new business opportunities to developers and eco-participants.
The Mind Mosaic Identity task system is built on a multi-chain compatible smart contract framework. It adopts a modular design to realize the full process automation of "task release-behavior verification-value allocation", forming a task distribution center in the Web3 world.
（2）AI digital human engine
An important part of the AI digital life ecosystem provides users with diverse ways of participating through digital human development and Web3 task system. The system's core logic revolves around the output and redemption of MP points, aiming to motivate users to receive rewards by interacting with AI and contributing data.
（3）SBT（Soul Bound Token）
Cosmic Cipher (CCipher) provides each user with a unique, non-transferable “Mind Mosaic Identity SBT” as the user’s digital identity in the Mind Mosaic ecosystem. This SBT is bound to the user's mobile phone and is used for future scenarios such as airdrop issuance and qualification confirmation.
The AI digital person on the phone is automatically associated with the user's "Mind Mosaic Identity SBT", ensuring that the digital person belongs to the user uniquely. When the digital man exports in GLB format, in addition to including the appearance model, an encrypted SBT reference is embedded.
（4）Cryptocurrency wallet
The wallet is a decentralized, non-custodial digital asset management tool, where users directly manage their assets through private keys or mnemonics. The wallet itself does not hold or store any asset data of the user, and all control belongs to the user.
Core functions and technical characteristics
① Decentralized and unmanaged design
Asset Management: The user's private key and mnemonic words are stored locally and kept by the user themselves. The wallet does not have access or control capabilities.
Privacy protection: The wallet does not collect or upload sensitive information from users, and all data operations are completed on the user's device.
② Local identity authentication mechanism
Access method: Unlock access to private keys or mnemonics through device local authentication methods (such as passwords, PINs, fingerprints, or facial recognition).
Security Design: The verification process is performed entirely within the user device, and the private key and mnemonics do not leave the local environment.
③ End-to-end encrypted communication
Data transmission: All communications between the wallet and the blockchain node are end-to-end encryption to ensure that the data cannot be intercepted or interpreted by third parties during transmission.
Protection scope: Only the sender and the receiver can decrypt the data to prevent external eavesdropping or tampering.
