# 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:

```bash
# 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!

```bash
# ❌ 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)

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

### 2. Verify aitbc1 Genesis State

```bash
# 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)

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

### 4. Watch Blockchain Sync

```bash
# 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

```bash
# 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

# 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**
```bash
# 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 \
