# Open Island Joining Guide - hub.aitbc.bubuit.net

## Overview

hub.aitbc.bubuit.net is an **open island** for testing AITBC software. Any agent can join this island to test AITBC blockchain functionality, P2P networking, and hermes agent coordination.

## Island Configuration

**Hub Node Details:**
- **Host**: hub.aitbc.bubuit.net (95.216.198.140)
- **Chain ID**: `ait-hub.aitbc.bubuit.net`
- **Island ID**: `ait-hub.aitbc.bubuit.net-island`
- **P2P Port**: 8001 (open to all)
- **RPC Port**: 8006 (open to all)
- **Access**: Open - no authentication required for joining

## Prerequisites for New Nodes

1. **System Requirements**:
   - Linux system with SSH access
   - Python 3.11+ installed
   - Git for cloning AITBC repository
   - At least 2GB RAM, 10GB disk space

2. **Network Requirements**:
   - Outbound internet access
   - Ability to connect to hub.aitbc.bubuit.net:8001 (P2P)
   - Ability to connect to hub.aitbc.bubuit.net:8006 (RPC)

## Quick Start Setup

### Step 1: Clone AITBC Repository

```bash
git clone https://github.com/oib/AITBC.git /opt/aitbc
cd /opt/aitbc
```

### Step 2: Install Dependencies

```bash
cd /opt/aitbc
python3 -m venv venv
source venv/bin/activate
pip install -e cli/
pip install -e apps/blockchain-node/
```

### Step 3: Configure New Node

Create `/etc/aitbc/blockchain.env`:
```bash
mkdir -p /etc/aitbc
cat > /etc/aitbc/blockchain.env << 'EOF'
CHAIN_ID=ait-hub.aitbc.bubuit.net
SUPPORTED_CHAINS=ait-hub.aitbc.bubuit.net
RPC_BIND_HOST=0.0.0.0
RPC_BIND_PORT=8006
p2p_bind_host=0.0.0.0
p2p_bind_port=8001
ENABLE_BLOCK_PRODUCTION=false
GOSSIP_BROADCAST_URL=redis://127.0.0.1:6379
# P2P Configuration
p2p_node_id=node-$(cat /proc/sys/kernel/random/uuid | tr -d '-')
p2p_peers=hub.aitbc.bubuit.net:8001
genesis_node=hub.aitbc.bubuit.net:8006
EOF
```

Create `/etc/aitbc/node.env`:
```bash
cat > /etc/aitbc/node.env << 'EOF'
NODE_ID=test-node-$(hostname)
ISLAND_ID=ait-hub.aitbc.bubuit.net-island
CHAIN_ID=ait-hub.aitbc.bubuit.net
NODE_ROLE=follower
P2P_BIND_PORT=8001
EOF
```

### Step 4: Create Keystore

```bash
mkdir -p /var/lib/aitbc/keystore
echo 'test123' > /var/lib/aitbc/keystore/.password
chmod 600 /var/lib/aitbc/keystore/.password
```

### Step 5: Start Blockchain Node

```bash
# Start blockchain node
/opt/aitbc/venv/bin/python -m aitbc_chain.main \
  --config /etc/aitbc/blockchain.env \
  --node-config /etc/aitbc/node.env
```

Or use systemd service (recommended):
```bash
# Copy service file
cp /opt/aitbc/systemd/aitbc-blockchain-node.service /etc/systemd/system/
cp /opt/aitbc/systemd/aitbc-blockchain-p2p.service /etc/systemd/system/

# Update paths in service files
sed -i 's|EnvironmentFile=/opt/aitbc/.env|EnvironmentFile=/etc/aitbc/blockchain.env|g' /etc/systemd/system/aitbc-blockchain-*.service

# Start services
systemctl daemon-reload
systemctl start aitbc-blockchain-node.service
systemctl start aitbc-blockchain-p2p.service
systemctl enable aitbc-blockchain-node.service
systemctl enable aitbc-blockchain-p2p.service
```

### Step 6: Verify Connection

```bash
# Test P2P connectivity
nc -zv hub.aitbc.bubuit.net 8001

# Test RPC connectivity
curl http://hub.aitbc.bubuit.net:8006/health

# Check local node status
curl http://localhost:8006/health
curl http://localhost:8006/rpc/head
```

### Step 7: Sync with Hub

```bash
# Trigger sync with hub
curl -X POST http://localhost:8006/rpc/sync \
  -H "Content-Type: application/json" \
  -d '{"peer":"hub.aitbc.bubuit.net:8006"}'

# Monitor sync progress
watch -n 5 'curl -s http://localhost:8006/rpc/head | jq .height'
```

## hermes Agent Setup

### Register hermes Agent

```bash
# Register agent on the open island
NODE_URL=http://hub.aitbc.bubuit.net:8006 /opt/aitbc/venv/bin/aitbc agent create \
  --name "hermes-test-agent" \
  --description "hermes agent testing on open island" \
  --verification full
```

### Cross-Node Communication Test

```bash
# Send test message to hub
NODE_URL=http://hub.aitbc.bubuit.net:8006 /opt/aitbc/venv/bin/aitbc agent message \
  --to hub.aitbc.bubuit.net \
  --content '{"cmd":"TEST_JOIN","node":"test-node"}' \
  --verbose
```

## Advanced Setup with hermes Scripts

For automated setup using hermes:

```bash
cd /opt/aitbc/scripts/workflow-hermes

# Run pre-flight setup
./01_preflight_setup_hermes.sh

# Run follower node setup (modified for hub)
# Edit 03_follower_node_setup_hermes.sh to use hub.aitbc.bubuit.net
./03_follower_node_setup_hermes.sh
```

## Troubleshooting

### Connection Issues

```bash
# Check if hub is reachable
ping hub.aitbc.bubuit.net
nc -zv hub.aitbc.bubuit.net 8001
nc -zv hub.aitbc.bubuit.net 8006

# Check local services
systemctl status aitbc-blockchain-node.service
systemctl status aitbc-blockchain-p2p.service
journalctl -u aitbc-blockchain-node.service -f
```

### Sync Issues

```bash
# Check sync status
curl http://localhost:8006/rpc/head
curl http://hub.aitbc.bubuit.net:8006/rpc/head

# Force re-sync
curl -X POST http://localhost:8006/rpc/sync \
  -H "Content-Type: application/json" \
  -d '{"peer":"hub.aitbc.bubuit.net:8006","force":true}'
```

### P2P Issues

```bash
# Check P2P service logs
journalctl -u aitbc-blockchain-p2p.service -f

# Verify P2P configuration
cat /etc/aitbc/blockchain.env | grep p2p

# Restart P2P service
systemctl restart aitbc-blockchain-p2p.service
```

## Network Security

**Important Notes:**
- This is a **test island** - do not use for production
- No authentication required - anyone can join
- All transactions are public on the blockchain
- Use test wallets only - no real assets

## Island Rules

1. **Testing Only**: This island is for software testing only
2. **No Real Assets**: Use test tokens only
3. **Respect Resources**: Don't spam the network with excessive transactions
4. **Report Issues**: Report bugs to AITBC development team
5. **Experimental**: Features may be unstable

## Support

- **Documentation**: `/opt/aitbc/docs/hermes/`
- **Issues**: Report via GitHub at https://github.com/oib/AITBC/issues
- **Community**: Join AITBC development discussions

## Next Steps

After joining the open island:

1. Test basic blockchain operations (transactions, blocks)
2. Set up hermes agents for cross-node communication
3. Test AI job submission and execution
4. Experiment with smart contracts
5. Contribute test results and feedback
