# AITBC — AI Token Blockchain

Decentralized GPU compute marketplace with blockchain-based job coordination, Ollama inference, ZK receipt verification, and token payments.

[![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg)](LICENSE)

## Overview

AITBC is a full-stack blockchain platform that connects GPU compute providers (miners) with AI workload consumers (clients) through a decentralized marketplace. The system handles job submission, miner matching, GPU inference execution, cryptographic receipt generation, and on-chain payment settlement.

**Key capabilities:**
- **Blockchain nodes** — PoA consensus, gossip relay, WebSocket RPC
- **Coordinator API** — Job lifecycle, miner registry, GPU marketplace, payments, billing, governance
- **GPU mining** — Ollama-based LLM inference with host GPU passthrough
- **Wallet daemon** — Balance tracking, receipt verification, ledger management
- **Trade exchange** — Bitcoin/AITBC trading with order book and price ticker
- **ZK circuits** — Zero-knowledge receipt verification (Circom/snarkjs)
- **Browser wallet** — Firefox extension for AITBC transactions
- **Explorer** — Real-time blockchain explorer (blocks, transactions, addresses, receipts)

## Quick Start

### Prerequisites

- Python 3.11+
- Node.js 18+ (for web apps and ZK circuits)
- PostgreSQL (optional, SQLite for development)
- Ollama (for GPU inference)

### Run Services Locally

```bash
# Start all services
./scripts/dev_services.sh

# Or start individually
cd apps/coordinator-api && uvicorn app.main:app --port 8000
cd apps/blockchain-node && python -m aitbc_chain.main
cd apps/wallet-daemon && uvicorn app.main:app --port 8002
```

### Run Tests

```bash
# CLI tests (141 unit + 24 integration)
pytest tests/cli/

# Coordinator API tests (billing + GPU marketplace)
pytest apps/coordinator-api/tests/

# Blockchain node tests
pytest tests/test_blockchain_nodes.py

# All tests together (208 passing)
pytest apps/coordinator-api/tests/ tests/cli/
```

### CLI Usage

```bash
pip install -e .

# Submit a job
aitbc client submit --type inference --prompt "Hello world"

# Register as a miner
aitbc miner register --gpu RTX4090

# GPU marketplace
aitbc marketplace gpu list
aitbc marketplace gpu book <gpu_id> --hours 1

# Wallet and governance
aitbc wallet balance
aitbc governance propose --type parameter_change --title "Update fee"
```

## Deployment

Services run in an Incus container with systemd units. See `systemd/` for service definitions and `scripts/deploy/` for deployment automation.

```bash
# Deploy to container
./scripts/deploy/deploy-to-container.sh

# Deploy blockchain nodes
./scripts/deploy/deploy-blockchain.sh
```
