Bittensor Subnet 85 "Vibe Miner" Skill

Bittensor Subnet 85 "Vibe Miner" Skill

Author: Mark Jeffrey
Description: Complete automated setup for mining Bittensor Subnet 85 (VidAIo) — video upscaling and compression mining with GPU acceleration.

What This Skill Does

Guides users through setting up profitable video processing miners on Bittensor Subnet 85:

• Upscaler miner — Upscale SD→HD, HD→4K using RealESRGAN (video2x)
• Compressor miner — High-quality video compression with AV1/HEVC
• Storage setup — BackBlaze B2 or Hippius decentralized storage
• Monitoring — Rank tracking, incentive monitoring, health checks
• Optimizations — Includes critical patches for VMAF quality scoring and video2x speed

Prerequisites

Required:

1. NVIDIA GPU — RTX 3090/4090 recommended (needs NVENC hardware encoding)
2. TAO Wallet — 1-2 τ minimum (≈$200-400 at current prices)
3. Storage — BackBlaze B2 account OR Hippius access
4. Linux — Ubuntu 22.04+ recommended
5. Skills — Basic command line, SSH access if using Vast.ai

Recommended Platform:

• Vast.ai — Rent RTX 4090 for $0.30/hr ($216/month)
• Alternative — Own hardware or other GPU cloud providers

Expected Returns

Based on live mining data (March 2026):

• Upscaler earnings: ~$14/day (top 5% miners)
• Compressor earnings: ~$9/day (top 65% miners)
• Combined: $23/day ($690/month)
• Break-even: ~2-3 weeks on Vast.ai rental

Returns vary with TAO price, network competition, and subnet emissions.

How to Use This Skill

Agent will guide you through:

1. Creating/importing TAO wallet
2. Setting up GPU instance (Vast.ai or bare metal)
3. Configuring storage (BackBlaze or Hippius)
4. Installing dependencies and mining software
5. Registering on subnet (costs ~0.13 τ per miner)
6. Starting miners and monitoring performance

What Makes This Different

Includes hard-won optimizations:

• ✅ VMAF quality scoring — Critical patch that many miners miss (causes rank decline)
• ✅ video2x speed optimization — 10-50x faster than default Python implementation
• ✅ Vast.ai port workarounds — Handles occupied ports (8080, 11111, 18384)
• ✅ Score decay awareness — 0.8 decay factor, strategies to maintain rank
• ✅ Dual miner setup — Both upscaler + compressor for maximum earnings

Agent Instructions

When user requests SN85 mining setup:

Phase 1: Prerequisites Check

1. Verify GPU availability (query user about Vast.ai vs own hardware)
2. Check TAO wallet exists (btcli wallet list)
3. Verify wallet balance (need 1-2 τ minimum)
4. Confirm storage choice (BackBlaze B2 or Hippius)

Phase 2: Environment Setup

1. If Vast.ai: Guide through instance creation (RTX 4090, Ubuntu 22.04, Docker)
2. If bare metal: Verify NVIDIA drivers, CUDA, docker/PM2
3. Clone vidaio-subnet repository
4. Install dependencies (use scripts/install.sh)

Phase 3: Storage Configuration

1. If BackBlaze: Guide through B2 bucket creation, save credentials
2. If Hippius: Set up using hippius skill, configure S3-compatible endpoint
3. Update miner configs with storage credentials

Phase 4: Apply Patches

1. Apply VMAF calculation patch (patches/validator_merger_vmaf.patch)
2. Verify video2x installation (should use CLI, not Python)
3. Test GPU encoding (NVENC support)

Phase 5: Registration

1. Create hotkeys if needed (btcli wallet new_hotkey)
2. Register upscaler on SN85 (costs 0.13 τ)
3. Register compressor on SN85 (costs 0.13 τ)
4. Configure port mappings (Vast.ai: map internal→external)

Phase 6: Start Miners

1. Launch PM2 services (upscaler, compressor, workers)
2. Verify axon connectivity
3. Wait for first tasks (upscaler should receive within 30-60min)

Phase 7: Monitor

1. Check incentive/rank with scripts/monitor.sh
2. Verify VMAF calculation in logs (look for "🎯 Calculating final video VMAF")
3. Alert if crash loops detected
4. Track earnings over immunity period (7200 blocks ≈ 24h)

Key Files

• SKILL.md — This file
• scripts/install.sh — Full dependency installation
• scripts/register.sh — Subnet registration helper
• scripts/monitor.sh — Status checking and alerts
• scripts/storage_setup.sh — BackBlaze/Hippius configuration
• patches/validator_merger_vmaf.patch — Critical quality scoring fix
• configs/miner_upscaler.json — Upscaler configuration template
• configs/miner_compressor.json — Compressor configuration template

Troubleshooting

Compressor crash loops:

• Check for Python syntax errors in validator_merger.py
• Verify VMAF patch applied correctly
• Look for port conflicts

Low incentive scores:

• Verify VMAF calculation is running (check logs for "🎯 Calculating")
• Ensure GPU encoding is working (NVENC)
• Check network connectivity (axon reachable)

Deregistration risk:

• Monitor incentive (if below 0.002, at risk)
• Upscaler has priority (better task frequency)
• Consider running upscaler only if capital limited

Safety Notes

• Test on testnet first if unsure
• Start with one miner to verify setup before registering second
• Monitor closely during immunity period (first 24h)
• Backups — Keep wallet mnemonics secure and offline
• Costs — Registration is non-refundable, calculate ROI before committing

Support

This skill packages real mining experience from March 2026. All optimizations are battle-tested.

Common issues solved:

• VMAF calculation disabled by default (causes rank decline)
• video2x Python implementation too slow (causes validator timeouts)
• Vast.ai port conflicts (8080, 11111, 18384 occupied)
• Score decay mechanics (0.8 factor, need frequent validator pings)
