Gateway Layer

* AI Gateway: Handles general AI inference tasks like CV, audio processing or sensor data analysis
* LLM Gateway: Manages the more resource intensive language model inference

Edge Network Layer

* Edge Devices: handle the actual computation
* Master Node: Manages orchestration, scheduling and control plane operations

Decentralized Layer

* DID: Essential for secure node authentication, reputation tracking and trust establishment.
* Smart Contracts: Critical for automated resource allocation, payment processing and SLA enforcement.
