Decentralized Truth Verification for Prediction Markets

1. Install System Dependencies

# Update system and install Python 3.11 + dev tools
sudo apt update && sudo apt upgrade -y
sudo apt install python3.11 python3.11-venv python3.11-dev git curl build-essential -y

2. Clone Repository

git clone https://github.com/degenpredict/bittensor-subnet-90-brain.git
cd bittensor-subnet-90-brain

3. Setup Environment

# Create and activate virtual environment
python3.11 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip

# Install PyTorch CPU version first (critical - prevents startup hangs)
pip install torch==2.7.1 --index-url https://download.pytorch.org/whl/cpu

# Install everything else
pip install -r requirements.txt

4. Create Wallet & Register

# Create coldkey first (your main wallet - keep this secure!)
btcli wallet new_coldkey --wallet.name my_wallet

# Create hotkey for first miner
btcli wallet new_hotkey --wallet.name my_wallet --wallet.hotkey miner_1

# Register on subnet (costs ~1 TAO each)
btcli subnets register --netuid 90 --wallet.name my_wallet --wallet.hotkey miner_1

# Optional: Create additional miners/validators and register them
# btcli wallet new_hotkey --wallet.name my_wallet --wallet.hotkey miner_2
# btcli subnets register --netuid 90 --wallet.name my_wallet --wallet.hotkey miner_2
# btcli wallet new_hotkey --wallet.name my_wallet --wallet.hotkey validator
# btcli subnets register --netuid 90 --wallet.name my_wallet --wallet.hotkey validator

5. Configure

# Copy configuration template
cp .env.example .env

Your .env file will contain these default names:

WALLET_NAME=my_wallet
HOTKEY_NAME=miner_1

If you used different names, edit with: nano .env

6. Start Everything

# Start all processes with available hotkeys
pm2 start ecosystem.config.js

# Check status
pm2 status
pm2 logs

7. Useful Commands

pm2 restart ecosystem.config.js    # Restart all
pm2 stop all                       # Stop all
pm2 logs miner_1                   # View specific logs
pm2 monit                          # Real-time monitoring
