📚 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.

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.

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.

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

Step 4: List Island Members

View all members of an island.

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.

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

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

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

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())
