RIP-0683: Console Mining Setup Guide

May 18, 2026 · View on GitHub

Overview

This guide walks you through setting up a retro game console as a RustChain miner using a Raspberry Pi Pico serial bridge. Console mining enables vintage hardware from 1983-2001 to earn RTC rewards through Proof of Antiquity consensus.

To our knowledge, this is the first blockchain to mine on vintage game console silicon.

Pin 9 (Start)                  → GPIO 7

Step 2: Flash Pico Firmware

Prerequisites

  • Raspberry Pi Pico
  • USB cable
  • Computer with Arduino IDE or PlatformIO

Installation

  1. Install Arduino IDE (if not already installed)

    # Ubuntu/Debian
    sudo snap install arduino
    
    # macOS
    brew install --cask arduino
    
    # Windows: Download from https://www.arduino.cc/en/software
    
  2. Add Pico board support

    • Open Arduino IDE
    • Go to File → Preferences
    • Add to "Additional Board Manager URLs":
      https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
      
    • Go to Tools → Board → Boards Manager
    • Search for "Raspberry Pi Pico"
    • Install "Raspberry Pi Pico/RP2040" by Earle Philhower
  3. Install dependencies

    • In Arduino IDE: Sketch → Include Library → Manage Libraries
    • Install:
      • SHA256 by Dominik Reichert
      • ArduinoJson by Benoit Blanchon
  4. Load firmware

    • Open miners/console/pico_bridge_firmware/pico_bridge.ino
    • Select board: Tools → Board → Raspberry Pi Pico → Raspberry Pi Pico
    • Select port: Tools → Port → /dev/ttyACM0 (Linux) or COM3 (Windows)
    • Click Upload (→)
  5. Verify installation

    • Open Serial Monitor (115200 baud)
    • Reset Pico
    • Should see: PICO_READY|RIP-0683 Console Bridge v1.0|

Step 3: Prepare Console ROM

N64 Attestation ROM

The console needs a custom ROM that:

  1. Receives nonce from Pico
  2. Computes SHA-256(nonce || wallet)
  3. Outputs result via controller port

ROM Source: See miners/console/n64_attestation_rom/ (future implementation)

Alternative: Pico-Only Mode

For consoles without custom ROM capability, the Pico can:

  1. Simulate controller polling
  2. Measure timing characteristics
  3. Compute hash on behalf of console (with reduced multiplier)

Step 4: Configure RustChain Node

Update Node Configuration

Edit your node's configuration file:

# config.py
CONSOLE_MINING_ENABLED = True
PICO_BRIDGE_PORT = "/dev/ttyACM0"  # Linux
# PICO_BRIDGE_PORT = "COM3"  # Windows
SUPPORTED_CONSOLE_ARCHS = [
    "nes_6502", "snes_65c816", "n64_mips",
    "genesis_68000", "gameboy_z80", "ps1_mips"
]

Start Node with Console Support

cd node
python3 rustchain_v2_integrated_v2.2.1_rip200.py --console-mining

Step 5: Submit Attestation

Manual Test

# Send ATTEST command to Pico
echo "ATTEST|abc123|RTC1Wallet001|$(date +%s)" > /dev/ttyACM0

# Read response
cat < /dev/ttyACM0

Expected response:

OK|PICO001|n64_mips|{"ctrl_port_cv":0.005,"rom_hash_time_us":847000,...}|<hash>

Automated Mining

The node automatically:

  1. Detects Pico bridge on serial port
  2. Sends challenge nonce
  3. Receives timing data and hash
  4. Validates anti-emulation checks
  5. Submits to consensus layer
  6. Distributes rewards to retro_console bucket

Step 6: Verify Mining Status

Check Node Logs

tail -f node/logs/rustchain.log | grep "console"

Expected output:

[CONSOLE] Registered n64_mips miner (PICO001)
[CONSOLE] Attestation passed: CV=0.005, ROM_time=847ms
[REWARDS] retro_console bucket: 3 miners, 0.333 share

Check Fleet Bucket Status

curl http://localhost:5000/api/miners/fleet_status

Response:

{
  "buckets": {
    "retro_console": {
      "miner_count": 3,
      "share": 0.333,
      "active_archs": ["n64_mips", "nes_6502", "ps1_mips"]
    }
  }
}

Troubleshooting

Pico Not Detected

Symptoms: Serial port not found, no response

Solutions:

  1. Check USB cable (some are charge-only)
  2. Hold BOOTSEL button while plugging in Pico
  3. Verify port: ls /dev/ttyACM* (Linux) or Device Manager (Windows)

CV Too Low (Emulator Detected)

Symptoms: ERROR|timing_too_uniform

Causes:

  • Console not powered on
  • Wrong controller port wiring
  • Emulator instead of real hardware

Solutions:

  1. Verify console is running attestation ROM
  2. Check controller port connections
  3. Ensure real hardware, not FPGA/emulator

ROM Hash Time Wrong

Symptoms: ERROR|Suspicious hardware: ROM execution time outside tolerance

Causes:

  • Wrong console architecture selected
  • Overclocked console
  • Timing measurement bug

Solutions:

  1. Verify correct SET_CONSOLE command sent to Pico
  2. Check console is stock (not overclocked)
  3. Increase tolerance in firmware (±15% → ±20%)

Fleet Detection Triggered

Symptoms: Reduced rewards, fleet_score > 0.5

Causes:

  • Multiple consoles on same IP/subnet
  • Correlated attestation timing
  • Similar fingerprint profiles

Solutions:

  1. Spread consoles across different networks
  2. Add random delay to attestation timing
  3. Each console should have unique Pico ID

Economics

Expected Rewards

Console miners share the retro_console bucket equally with other console miners.

Example (assuming 10 total miners, 3 in retro_console):

  • Total block reward: 1.5 RTC
  • retro_console bucket share: 1.5 / 3 = 0.5 RTC
  • Your console share: 0.5 / (number of console miners)

With 2.5x multiplier (N64):

  • Base reward × 2.5 = higher share within bucket

ROI Calculation

Initial Investment:

  • Console: $20-50 (eBay)
  • Pico: $4
  • Adapter: $5 (parts)
  • Total: ~$30-60

Annual Revenue (estimated):

  • 0.1-0.5 RTC/day × 365 days × $0.50/RTC = $18-91/year

Payback Period: 4-36 months

Note: Rewards depend on network participation, RTC price, and console bucket size.

Advanced Topics

Multi-Console Bridge

One Pico can manage multiple consoles:

  • Use GPIO multiplexer
  • Switch controller port connections
  • Each console gets unique miner ID

Pico W Standalone Mode

Pico W can operate without PC:

  • Connects to WiFi
  • Sends attestations directly to node
  • Requires custom firmware build

Custom ROM Development

Develop attestation ROMs for additional consoles:

  • Use existing dev tools (gcc6502, mips64-elf-gcc)
  • Link against librustchain (SHA-256 implementation)
  • Output ROM format (.nes, .z64, .bin)

Security Considerations

Anti-Spoof Measures

  1. Pico board ID - Unique OTP ROM (cannot reprogram)
  2. Timing profiles - Real hardware has characteristic jitter
  3. ROM execution time - Must match known CPU performance
  4. Fleet detection - IP clustering, timing correlation

Known Limitations

  • FPGA consoles may pass timing checks (under research)
  • High-end emulators + fake bridge possible (mitigated by fleet detection)
  • Console farms limited by bucket normalization

Future Work

Phase 2 (Q2 2026)

  • Additional consoles: Atari 2600, Neo Geo, Dreamcast
  • Pico W standalone firmware
  • Multi-console bridge support

Phase 3 (Q3 2026)

  • Hardware anchor on Ergo
  • On-chain attestation registry
  • Console-specific NFT badges
