PinkyBrain

P2P distributed AI platform for every domain — health, education, science, art, music, agriculture, law. Share compute, query specialists, sync memory. Ed25519 + Web of Trust + E2E encryption.

PinkyBrain — P2P Distributed AI Network

Become a node on the PinkyBrain. Share compute, query specialists, sync memory across peers — all with Ed25519 identity and E2E encryption.

⚠️ Security Rules (NON-NEGOTIABLE)

Rule	Detail
Cloud models stay private by default	OpenAI, Anthropic, and other cloud models are not shared on mesh by default. Sharing requires explicit force=True + clear cost warning — the user MUST understand their API keys will be used by others
Strong P2P_SECRET	Must be changed from default; weak secrets are rejected at startup
Ed25519 + HMAC	All P2P communication uses Ed25519 identity and HMAC authentication
Web of Trust	Public mesh participation requires WoT verification
E2E encryption	Queries routed through distributed inference are end-to-end encrypted
shared_models/ only	Only models in shared_models/ are visible to mesh — mesh NEVER reads outside this zone
Resource Guard	Auto-pauses sharing when CPU/RAM thresholds exceeded
Stealth mode	Share compute but stay hidden on tracker
Zero query logging	No query or response data logged on public mesh. Operational events (connect/disconnect) may still be logged locally.
No data leakage	Strict isolation between private and public networks

Installation

Quick Install

bash

# Clone the PinkyBrain repository
git clone https://github.com/PinkyBrain-ai/pinkybrain.git ~/pinkybrain
cd ~/pinkybrain

# Create virtual environment and install dependencies
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

# Generate Ed25519 identity (first run)
python -m pinkybrain.v5 identity init

# Configure (interactive — sets P2P_SECRET, sharing preferences, etc.)
python -m pinkybrain.v5 config init

First Run

bash

# Start the node (foreground, for testing)
python -m pinkybrain.v5 serve

# Or start as a background daemon
python -m pinkybrain.v5 serve --daemon

The node exposes an HTTP API on port 8080 by default.

---

Auto-Discovery

When the skill needs to find a running PinkyBrain node, it checks in order:

1. PINKYBRAIN_URL environment variable (e.g. http://my-node:8080)
2. http://localhost:8080/api/ping — default port
3. http://localhost:8081/api/ping — alternate port
4. Tailscale peers — reads Tailscale config for peers running PinkyBrain
5. mDNS discovery — _pinkybrain._tcp.local. service discovery

The first responding endpoint is used for all subsequent API calls.

Discovery Helper

bash

# In any command, omit --url to trigger auto-discovery:
pinkybrain status          # finds node automatically
pinkybrain peers           # same

---

Agent Capabilities

Node Status & Health

bash

# Check if PinkyBrain is running and healthy
pinkybrain status          # → GET /api/status
pinkybrain ping            # → GET /api/ping

AI Queries (Specialist Router)

PinkyBrain routes queries through 12 specialist profiles with 6 multi-LLM modes:

Mode	How it works
single	Route to the best-fit specialist
vote	Multiple specialists vote, majority wins
chain	Specialists process sequentially, each building on the last
fuse	Merge responses from multiple specialists
compare	Return all specialist responses side-by-side
specialist	Explicit specialist selection

bash

# Query the mesh
pinkybrain query "Explain quantum entanglement" --mode single
pinkybrain query "Debug this code" --mode chain --specialist coder
pinkybrain query "Is this claim accurate?" --mode vote --specialists factchecker,skeptic

P2P Networking

bash

# Discover and manage peers
pinkybrain peers                    # → GET /api/peers
pinkybrain discover                 # → GET /api/discover

# Join/leave the public mesh
pinkybrain mesh join                # → POST /api/network/mesh/join
pinkybrain mesh leave               # → POST /api/network/mesh/leave

CRDT Memory

Distributed, eventually-consistent key-value store synced across all peers.

bash

# Read from mesh memory
pinkybrain memory get my_key        # → GET /api/memory/{key}

# Write to mesh memory
pinkybrain memory set my_key "value" # → POST /api/memory/set

Model Registry

Catalog models with hash verification and Ed25519 signatures.

bash

# List available models
pinkybrain models list              # → GET /api/models

# Share a model to the mesh (ONLY from shared_models/)
pinkybrain models share llama3     # → POST /api/models/{name}/share

# Stop sharing a model
pinkybrain models unshare llama3   # → POST /api/models/{name}/unshare

⚠️ Only models in shared_models/ can be shared. Cloud models (OpenAI, Anthropic) are never visible to the mesh.

Credit System

Earn credits by sharing compute, spend credits to query others.

bash

# Check a peer's credit score
pinkybrain score peer_id            # → GET /api/score/{peer}

Resource Guard

Auto-pauses model sharing when your system is under load. Configurable thresholds:

bash

# Check resource status (included in /api/status)
pinkybrain status                   # shows CPU/RAM + guard state

Configuration (in pinkybrain.yaml):

yaml

resource_guard:
  cpu_threshold: 80    # % CPU — pause sharing above this
  ram_threshold: 85    # % RAM — pause sharing above this
  cooldown_secs: 300   # wait before resuming

Capabilities & Hardware

bash

# Report node hardware capabilities
pinkybrain capabilities             # → GET /api/capabilities

Daemon Management

bash

# Check daemon status
pinkybrain daemon status             # → GET /api/daemon

# Start/stop the daemon
pinkybrain serve --daemon
pinkybrain serve --stop

Updates

bash

# Check for PinkyBrain updates
pinkybrain update check             # → GET /api/update

# Apply updates
pinkybrain update apply             # Downloads verified update (SHA-256 + Ed25519 signature check)

Conversation Store

Persistent conversation history with search, export, and privacy levels.

bash

# Conversations are stored automatically per session
# Search past conversations
pinkybrain conversations search "quantum"

# Export a conversation
pinkybrain conversations export <session_id>

# Privacy levels: private | peers-only | public
pinkybrain conversations set-privacy <session_id> peers-only

Stealth Mode

Share compute without appearing on the public tracker:

bash

pinkybrain config set stealth true
# Or in pinkybrain.yaml:
# stealth: true

Your node contributes to the mesh but its identity/IP is hidden from peer lists.

Troubleshooting

Problem	Solution
Node won't start	Check P2P_SECRET is set and strong
Can't discover peers	Verify mDNS/Tailscale; check pinkybrain discover
Models not sharing	Ensure model is in shared_models/ dir
Cloud model leaked	Impossible by default — cloud models require explicit force=True to share. Check config if concerned
High CPU/RAM	Resource Guard auto-pauses; lower thresholds in config
Credit balance zero	Earn by sharing compute or set initial_balance
