Multi-node blockchain deployment and setup workflow

Multi-Node Blockchain Deployment Workflow

This workflow sets up a two-node AITBC blockchain network (aitbc1 as genesis authority, aitbc as follower node), creates wallets, and demonstrates cross-node transactions.

Prerequisites

• SSH access to both nodes (aitbc1 and aitbc)
• Both nodes have the AITBC repository cloned
• Redis available for cross-node gossip
• Python venv at /opt/aitbc/venv
• AITBC CLI tool available (aliased as aitbc)
• CLI tool configured to use /etc/aitbc/blockchain.env by default

Pre-Flight Setup

Before running the workflow, ensure the following setup is complete:

# Run the pre-flight setup script
/opt/aitbc/scripts/workflow/01_preflight_setup.sh

Directory Structure

• /opt/aitbc/venv - Central Python virtual environment
• /opt/aitbc/requirements.txt - Python dependencies (includes CLI dependencies)
• /etc/aitbc/.env - Central environment configuration
• /var/lib/aitbc/data - Blockchain database files
• /var/lib/aitbc/keystore - Wallet credentials
• /var/log/aitbc/ - Service logs

Steps

Environment Configuration

The workflow uses the single central /etc/aitbc/.env file as the configuration for both nodes:

• Base Configuration: The central config contains all default settings
• Node-Specific Adaptation: Each node adapts the config for its role (genesis vs follower)
• Path Updates: Paths are updated to use the standardized directory structure
• Backup Strategy: Original config is backed up before modifications
• Standard Location: Config moved to /etc/aitbc/ following system standards
• CLI Integration: AITBC CLI tool uses this config file by default

🚨 Important: Genesis Block Architecture

CRITICAL: Only the genesis authority node (aitbc1) should have the genesis block!

# ❌ WRONG - Do NOT copy genesis block to follower nodes
# scp aitbc1:/var/lib/aitbc/data/ait-mainnet/genesis.json aitbc:/var/lib/aitbc/data/ait-mainnet/

# ✅ CORRECT - Follower nodes sync genesis via blockchain protocol
# aitbc will automatically receive genesis block from aitbc1 during sync

Architecture Overview:

1. aitbc1 (Genesis Authority): Creates genesis block with initial wallets
2. aitbc (Follower Node): Syncs from aitbc1, receives genesis block automatically
3. Wallet Creation: New wallets attach to existing blockchain using genesis keys
4. Access AIT Coins: Genesis wallets control initial supply, new wallets receive via transactions

Key Principles:

• Single Genesis Source: Only aitbc1 creates and holds the original genesis block
• Blockchain Sync: Followers receive blockchain data through sync protocol, not file copying
• Wallet Attachment: New wallets attach to existing chain, don't create new genesis
• Coin Access: AIT coins are accessed through transactions from genesis wallets

1. Prepare aitbc1 (Genesis Authority Node)

# Run the genesis authority setup script
/opt/aitbc/scripts/workflow/02_genesis_authority_setup.sh

2. Verify aitbc1 Genesis State

# Check blockchain state
curl -s http://localhost:8006/rpc/head | jq .
curl -s http://localhost:8006/rpc/info | jq .
curl -s http://localhost:8006/rpc/supply | jq .

# Check genesis wallet balance
GENESIS_ADDR=$(cat /var/lib/aitbc/keystore/aitbc1genesis.json | jq -r '.address')
curl -s "http://localhost:8006/rpc/getBalance/$GENESIS_ADDR" | jq .

3. Prepare aitbc (Follower Node)

# Run the follower node setup script (executed on aitbc)
ssh aitbc '/opt/aitbc/scripts/workflow/03_follower_node_setup.sh'

4. Watch Blockchain Sync

# On aitbc, monitor sync progress
watch -n 2 'curl -s http://localhost:8006/rpc/head | jq .height'

# Compare with aitbc1
ssh aitbc1 'curl -s http://localhost:8006/rpc/head | jq .height'

# Alternative: Batch sync for faster initial setup
if [ $(curl -s http://localhost:8006/rpc/head | jq .height) -lt 10 ]; then
  echo "Importing first 10 blocks from aitbc1..."
  for height in {2..10}; do
    curl -s "http://10.1.223.40:8006/rpc/blocks-range?start=$height&end=$height" | \
      jq '.blocks[0]' > /tmp/block$height.json
    curl -X POST http://localhost:8006/rpc/importBlock \
      -H "Content-Type: application/json" -d @/tmp/block$height.json
    echo "Imported block $height"
  done
fi

5. Create Wallet on aitbc

# Run the wallet creation script
/opt/aitbc/scripts/workflow/04_create_wallet.sh

🔑 Wallet Attachment & Coin Access:

The newly created wallet on aitbc will:

1. Attach to Existing Blockchain: Connect to the blockchain created by aitbc1
2. Use Genesis Keys: Access the blockchain using the genesis block's cryptographic keys
3. Receive AIT Coins: Get coins through transactions from genesis wallets
4. No New Genesis: Does NOT create a new genesis block or chain

Important Notes:

• The wallet attaches to the existing blockchain network
• AIT coins are transferred from genesis wallets, not created
• The wallet can only transact after receiving coins from genesis
• All wallets share the same blockchain, created by aitbc1

block_time_seconds=2  # Default: 10, faster for testing

Network Optimization

Optimize P2P settings:

p2p_bind_port=7070  # Standard port for P2P communication

Database Performance

Ensure proper database permissions and location:

db_path=/var/lib/aitbc/data/ait-mainnet/chain.db
chmod 755 /var/lib/aitbc/data

System Resource Optimization

Memory Management

Monitor memory usage:

systemctl status aitbc-blockchain-node --no-pager | grep Memory

CPU Optimization

Set process affinity for better performance:

echo "CPUAffinity=0-3" > /opt/aitbc/systemd/cpuset.conf

Monitoring and Metrics

Real-time Monitoring

Monitor blockchain height in real-time:

watch -n 2 'curl -s http://localhost:8006/rpc/head | jq .height'

Performance Metrics

Check block production rate:

curl -s http://localhost:8006/rpc/info | jq '.genesis_params.block_time_seconds'

Troubleshooting

Common Issues and Solutions

Systemd Service Failures

# Check service status and logs
systemctl status aitbc-blockchain-*.service --no-pager
journalctl -u aitbc-blockchain-node.service -n 10 --no-pager

# Fix environment file issues
find /etc/systemd/system/aitbc-blockchain-*.service.d/ -name "*.conf" -exec grep -l "EnvironmentFile" {} \;
find /etc/systemd/system/aitbc-blockchain-*.service.d/ -name "*.conf" -exec sed -i 's|EnvironmentFile=/opt/aitbc/.env|EnvironmentFile=/etc/aitbc/blockchain.env|g' {} \;

# Fix virtual environment paths in overrides
find /etc/systemd/system/aitbc-blockchain-*.service.d/ -name "override.conf" -exec sed -i 's|/opt/aitbc/apps/blockchain-node/.venv/bin/python3|/opt/aitbc/venv/bin/python3|g' {} \;

# Reload and restart
systemctl daemon-reload
systemctl restart aitbc-blockchain-node aitbc-blockchain-rpc

RPC Service Issues

# Check if RPC is accessible
curl -s http://localhost:8006/rpc/head | jq .

# Manual RPC start for debugging
cd /opt/aitbc/apps/blockchain-node
PYTHONPATH=/opt/aitbc/apps/blockchain-node/src:/opt/aitbc/apps/blockchain-node/scripts \
  /opt/aitbc/venv/bin/python -m uvicorn aitbc_chain.app:app --host 0.0.0.0 --port 8006

Keystore Issues

# Create keystore password file and check permissions
/opt/aitbc/scripts/workflow/01_preflight_setup.sh

Sync Issues

# Check and fix blockchain synchronization issues
/opt/aitbc/scripts/workflow/08_blockchain_sync_fix.sh

General Troubleshooting

• Services won't start: Check /var/log/aitbc/ for service logs
• Sync issues: Verify Redis connectivity between nodes
• Transaction failures: Check wallet nonce and balance
• Permission errors: Ensure /var/lib/aitbc/ is owned by root with proper permissions
• Configuration issues: Verify /etc/aitbc/blockchain.env file contents and systemd service EnvironmentFile paths
