Offline Protocol’s system is structured into three layers, ensuring flexibility, scalability, and interoperability.

​
1. Infrastructure Layer

  • Offline Network: Core peer-to-peer layer using WiFi-Direct and Bluetooth Mesh.
  • DORS (Dynamic Offline Relay Switch): Smart routing engine selecting the optimal path across nodes.
  • Relay & Hub Devices: Endpoints can also serve as relays to extend the network.
Core Architecture

​
2. Application Layer

  • Offline ID: Universal usernames serving as portable, protocol-wide identities.
  • Fernweh: Fully offline, E2E encrypted communication platform built on Offline Protocol.
  • Service Hooks: APIs for identity, discovery, and data exchange.

​
3. User Layer

  • Device Integration: Devices auto-resolve via Offline ID.
  • Local Data Persistence: Information is cached locally until sync.
  • Online Uplinks (optional): Nodes with internet access act as bridges, enabling cross-network communication.
