AITBC — AI Token Blockchain

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

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

# 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

# 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

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.

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

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