INTERFACE

Four surfaces. State over people. Execution over engagement.

01

Capabilities

Structured inventory. Skills, tools, resources, availability. Binary and quantitative. No bios.

Can repair small engines
Has solar inverter
Available 10 hrs/week
02

Needs / Tasks

Post needs as executable units. Location, deadline, risk, dependencies. Claimable. Offline creation.

Location Deadline Risk level
03

Cell

Current group composition. Redundancy gaps. Trust state. Explicit fragility warnings. No chat-first.

2 members have overlapping skills
No medical capability

Decisions

Propose → Object → Execute. Time-boxed. Silence equals consent. Prevents paralysis.

ARCHITECTURE

Open for trust. Closed for execution. Optimized for survival.

The Substrate

A 1:1 fork of the Bitchat core. Handles Noise Protocol handshakes, P2P transport, and local data persistence. Fully auditable, stateless, and forkable.

The Intelligence

Pangaea’s unique coordination layer. Decodes encrypted substrate events into the Cell State, skill-matching graphs, and survival-task dependencies.

Local-First

No global usernames. No centralized databases. All coordination logic and identity keys live on-device, never on a server.

Mesh Topology

Designed for total infrastructure failure. Syncs via LoRa, Bluetooth, or LAN. Cells function as self-sufficient enclaves when the world goes dark.

EXECUTION LAYER

THE COMPOSITION ENGINE

Private group formation via constraint-satisfaction, not social matchmaking.

DECODES (OPEN)
  • Encrypted Skill Graphs
  • Proximity Envelopes
  • Dependency Events
OPTIMIZES (CLOSED)
  • Cell Fragility Analysis
  • Redundancy Gap Logic
  • Execution Flow Scoring
The engine decodes the mesh to provide a real-time Cell State.

TECHNICAL STACK

Built like emergency infrastructure, not a startup product.

HARDWARE

THE SIDECAR

LoRaWAN Mesh Repeater. Extends range from 50 feet to 5+ miles.

CORE
LoRa Radio (915/868 MHz)
POWER
10,000mAh battery + solar controller
BUILD
IP67 waterproof, no screen to break
FIRMWARE
Meshtastic / Reticulum compatible
I/O
USB-C + physical purge button
SHELF LIFE
10+ years (replaceable 18650 cells)
"The app is free. If you want your cell to communicate over 5 miles instead of 50 feet, buy the Sidecar."
  • Holds identity and mesh state
  • Works as "dead drop" store-and-forward
  • Phone is disposable, Sidecar persists
  • Pangaea-compatible out of the box

INFRASTRUCTURE REQUIREMENTS

SURVIVAL-GRADE SECURITY

Coordination without a paper trail.

01

The Substrate: Auditable Core

Pangaea’s transport layer is an 1-to-1 fork of the Bitchat protocol. We utilize the Noise Protocol Framework (Noise_XX_25519_ChaChaPoly_SHA256) to ensure that group coordination logic is never exposed to intermediate relay nodes.

git diff main..bitchat-upstream/main
02

Hardware: The "Dumb Pipe" Sidecar

The Sidecar bridge operates as a stateless relay. It extends the mesh range to 5 miles via LoRa but lacks the keys to decrypt the coordination events passing through it. Physical seizure of hardware yields zero group data.

PANIC PROTOCOL

Pangaea inherits the Triple-Tap Emergency Wipe feature. In a high-risk encounter, three taps on the app logo instantly erases all local coordination data, task lists, and cryptographic identities.
