SIAR — Survivable Identity & Autonomous Routing Platform

SURVIVABILITY MANDATE

Engineered for Complete Grid Collapse

Traditional messaging apps depend on AWS, cellular towers, and central DNS. SIAR operates directly peer-to-peer over physical radio waves.

Zero Infrastructure

No central servers, identity registrars, or phone number databases. Nodes discover each other directly over local radio hardware.

RFC Compliance: Ad-Hoc Gossip Mesh

Delay-Tolerant Networking

Store-carry-forward routing bridges physical air-gaps. Messages travel via physical motion of vehicles and walking nodes during total blackouts.

DTN Spec: Bundle Protocol v7 (RFC 9171)

Pure-Rust Bare Metal

Memory-safe, high-performance engine compiled to native musl binaries, Android NDK, and browser WebAssembly with zero garbage collection pauses.

Toolchain: Rust 2024 Edition + Wasm

MLS Post-Compromise Security

OpenMLS tree ratchets provide forward secrecy and self-healing keys, ensuring past and future chats remain secure even if a device is temporarily captured.

Cryptography: RFC 9420 + Ed25519

DEPLOYMENT TOPOLOGY

Two Modes. One Unified Core.

Run SIAR as a full-featured user app with AV1/Opus codecs, or deploy as a headless emergency solar repeater.

Tactical Multi-Platform GUI

Native Android (Jetpack Compose) and Desktop (Dioxus/Rust) interface with zero tracking, built-in map mesh topology overlays, offline voice notes, and hardware-accelerated media streaming.

🛡️ Zero Leaks: No push notification relays through Google FCM or Apple APNs.
🎙️ Opus Voice & AV1 Video: Ultra-compressed voice memos sent directly over peer-to-peer Wi-Fi Direct.
🔋 Battery Optimized: Intelligent Bluetooth radio duty-cycling consumes less than 3% battery per 24 hours.

Headless Emergency Node Daemon

Deploy siar-emergency-node on a $15 Raspberry Pi Zero, solar router, or vehicle. Operates autonomously for months with captive Wi-Fi portals for disaster victims without the app.

☀️ Solar & Low Power: Operates on 1.2W continuous draw.
📶 Wi-Fi Captive Portal: Survivors connect their browser to read emergency broadcasts without installing any software.
📦 Massive DTN Cache: Up to 512GB of encrypted multi-hop bundle storage on local MicroSD/NVMe.
