3. SoulBoundRing Hardware Details

3.1 Patent‑Grade Optical Sensor Module

A proprietary miniature CIS module embeds photodiodes, green/red/infrared LEDs, and a BP‑1 image sensor into a micro‑cavity, delivering 50.5 mm omni‑directional resolution and dynamic noise suppression. Continuous blood‑flow variation, HRV, skin temperature, and micro‑vibrations are captured simultaneously, providing rich data for context modeling and personalized agents.

3.2 On‑Device AI Engine

A low‑power AI module supports local model loading and inference, enabling agents to process data and respond in real time without centralized servers. Models support online learning and fine‑tuning, letting users build personalized data labels through everyday use and supplying traceable, targeted distributed data for large‑scale agent networks.

3.3 Encrypted Identity & Payments

With a lightweight TEE‑based crypto module, the ring embeds a Web3 wallet, DID, and on‑chain signing mechanisms. Core features:

• Local signing & authentication

• Seamless encrypted payments

• Event‑driven on‑chain asset operations

3.4 Device‑as‑Node Capabilities

• Data producer — Biometric signals mapped (with consent) into on‑chain data assets.

• Edge compute node — Runs lightweight agents locally.

• Agent‑service consumer — Receives real‑time feedback.

• Resource contributor — Aggregates household GPUs, mobile devices, ARM chips.

• Incentivized collaborator — Earns native $Kairos tokens.
