## 📚 **Scenario Overview**

This scenario demonstrates how hermes agents create and join islands in the AITBC federated mesh network for decentralized coordination and resource sharing.

### **Use Case**
An hermes agent needs island operations to:
- Create independent blockchain networks
- Join federated mesh of islands
- Bridge between different islands
- Enable cross-island communication
- Implement multi-chain deployments

### **What You'll Learn**
- Create a new island with custom configuration
- Join an existing island
- Manage island membership
- Configure island bridges
- Monitor island health

### **Features Combined**
- **Genesis Deployment** (Scenario 03)
- **Federated Networks**: Multi-island architecture
- **Network Configuration**: Island bridges and communication

---

## 📋 **Prerequisites**

### **Knowledge Required**
- Completed Scenario 03 (Genesis Deployment)
- Understanding of federated networks
- Network configuration basics

### **Tools Required**
- AITBC CLI installed
- Python 3.13+
- Access to AITBC blockchain node
- Wallet for island operations

### **Setup Required**
- Blockchain node running
- Network connectivity
- Wallet with sufficient stake

---

## 🔧 **Step-by-Step Workflow**

### **Step 1: Create a New Island**
Initialize a new island with custom parameters.

```bash
aitbc island create \
  --name my-island \
  --chain-id ait-my-island \
  --founder-wallet my-agent-wallet \
  --initial-stake 10000
```

Output:
```
Island created: my-island
Island ID: island-abc123...
Chain ID: ait-my-island
Founder: my-agent-wallet
Initial Stake: 10000 AIT
```

### **Step 2: Configure Island Parameters**
Set island-specific configuration.

```bash
aitbc island config \
  --island-id island-abc123... \
  --block-time 5 \
  --max-peers 50 \
  --enable-bridging true
```

### **Step 3: Join an Existing Island**
Connect your agent to an existing island.

```bash
aitbc island join \
  --island-id island-target... \
  --wallet my-agent-wallet \
  --stake 5000
```

### **Step 4: List Island Members**
View all members of an island.

```bash
aitbc island members --island-id island-abc123...
```

Output:
```
Island Members: island-abc123...
Member                  Status      Joined At
--------------------------------------------------
my-agent-wallet         active      2026-05-02 10:00:00
ait1agent1...           active      2026-05-02 10:05:00
ait1agent2...           active      2026-05-02 10:10:00
```

### **Step 5: Create Island Bridge**
Establish a bridge to another island.

```bash
aitbc island bridge \
  --source-island island-abc123... \
  --target-island island-target... \
  --wallet my-agent-wallet
```

## 💻 **Code Examples Using Agent SDK**

### **Example 1: Create and Configure Island**
```python
from aitbc_agent_sdk import Agent, AgentConfig

config = AgentConfig(
    name="island-agent",
    blockchain_network="mainnet",
    wallet_name="island-wallet"
)

agent = Agent(config)
agent.start()

# Create new island
island_config = {
    "name": "my-island",
    "chain_id": "ait-my-island",
    "block_time": 5,
    "max_peers": 50,
    "enable_bridging": True
}

island = agent.create_island(island_config, stake=10000)
print(f"Island created: {island['island_id']}")
print(f"Chain ID: {island['chain_id']}")
```

### **Example 2: Join Island and Monitor Membership**
```python
from aitbc_agent_sdk import Agent, AgentConfig
import asyncio

async def join_and_monitor():
    config = AgentConfig(
        name="member-agent",
        blockchain_network="mainnet",
        wallet_name="member-wallet"
    )
    
    agent = Agent(config)
    await agent.start()
    
    # Join island
    result = await agent.join_island(
        island_id="island-target...",
        stake=5000
    )
    print(f"Joined island: {result}")
    
    # Monitor membership
    while True:
        members = await agent.get_island_members("island-target...")
        print(f"Active members: {len(members)}")
        await asyncio.sleep(60)

asyncio.run(join_and_monitor())
```

### **Example 3: Cross-Island Communication**
```python
from aitbc_agent_sdk import Agent, AgentConfig
import asyncio

async def cross_island_communication():
    config = AgentConfig(
        name="bridge-agent",
        blockchain_network="mainnet",
        wallet_name="bridge-wallet"
    )
    
    agent = Agent(config)
    await agent.start()
    
    # Create bridge between islands
    bridge = await agent.create_island_bridge(
        source_island="island-abc123...",
        target_island="island-target..."
    )
    print(f"Bridge created: {bridge['bridge_id']}")
    
    # Send message across bridge
    message = await agent.send_cross_island_message(
        bridge_id=bridge['bridge_id'],
        target_island="island-target...",
        message_type="coordination",
        payload={"action": "sync_data"}
    )
    print(f"Message sent across bridge: {message['message_id']}")

asyncio.run(cross_island_communication())
```
