2. VitaWatch Product Overview

VitaWatch is a smart watch product built on a Web3 architecture, designed for next-generation smart terminal scenarios. It not only possesses the health management capabilities of traditional wearable devices but also integrates an encrypted payment stack, autonomous AI models, and a data governance mechanism, achieving a three-in-one functionality of payment gateway, data assetization, and intelligent interaction.

The core design philosophy of VitaWatch is user-centric, enabling every user to truly control their own data and assets. Through a trusted terminal, users can access the on-chain world and, with the assistance of AI, live and make decisions more intelligently and freely. As the most cutting-edge hardware entry point in the Web3 ecosystem, VitaWatch aims to redefine the relationship between users and data, identity, and intelligence, becoming the personal operating system of the on-chain era.

VitaWatch's product architecture consists of two major layers:

• Device-Side Hardware System: Comprising a watch face master control module, sensor cluster, secure payment module, and edge AI chip, paired with a highly efficient, low-power smart operating system and encrypted wallet components. This setup enables local data collection, inference, and encrypted storage.

• Backend Network Stack: Constructing a Web3 foundational service layer consisting of a multi-chain compatible wallet, payment gateway, on-chain identity (DID), data marketplace protocol, and AI training interface, providing strong and scalable on-chain support for the device.

Both layers are connected through secure communication protocols and local signature mechanisms, enabling private data processing, controllable on-chain assets, and collaborative operation of trusted AI services.

2.1 Core Capabilities

• On-Chain Payment Terminal: The watch is equipped with a multi-chain encrypted wallet and payment SDK, supporting NFC, QR codes, and other methods for fast on-chain asset payments, transfers, and transactions. It integrates a hardware-level security module to ensure the trustworthiness of private key storage and sensitive operations, truly transforming the watch into a personal crypto-financial gateway.

• Data Assetization System: Health and behavioral data collected by the watch undergo privacy computing and encryption processing. With user authorization, the data can be uploaded to the data marketplace protocol, allowing users to autonomously decide whether to participate in training, sharing, or trading. This enables data ownership confirmation and revenue attribution while providing real, compliant individual data for AI training.

• AI Health Assistant & Agent Container: VitaWatch features a lightweight, self-developed AI model capable of local health data analysis, risk alerts, and personalized recommendations. Additionally, as an Agent container, it supports the deployment of user-customized or third-party plugin-based AI Agents, extending the watch's service boundaries and creating an interactive, adaptive, and programmable intelligent assistant experience.

2.2 Advantages of VitaWatch

• Paradigm Shift from "Centralized Service Terminals" to "User-Owned Devices": VitaWatch genuinely returns data control and asset sovereignty to users.

• Native Integration of Payments, Data, and Intelligence: By combining on-chain infrastructure with hardware-accelerated architecture, VitaWatch eliminates fragmented user experiences.

• Advanced Privacy Protection: Utilizing cryptographic solutions such as ZK (Zero-Knowledge Proofs) and FHE (Fully Homomorphic Encryption), as well as supporting on-chain authorization and the principle of minimal data usage, VitaWatch ensures a balance between data value and user privacy rights.

Extensible Plugin Architecture & Agent Programming Interface: Expanding the service scope of wearable devices beyond mere information recording tools, VitaWatch transforms into an intelligent companion for users' on-chain lives.
