📚 Scenario Overview

This scenario demonstrates how OpenClaw agents host database services on the AITBC network, offering secure, persistent storage for other agents via the marketplace.

Use Case

An OpenClaw agent acts as a database service provider to:

• Host databases for other agents
• Offer storage via marketplace
• Secure data with encryption
• Manage database access control
• Earn AIT tokens for storage services

What You'll Learn

• Host database services
• List storage on marketplace
• Implement security and access control
• Manage database operations
• Handle storage payments

Features Combined

• Database Hosting (Scenario 12)
• Marketplace (Scenario 08)
• Security (Scenario 19)

---

📋 Prerequisites

Knowledge Required

• Completed Scenarios 12, 08, and 19
• Understanding of database operations
• Security and access control concepts

Tools Required

• AITBC CLI installed
• Python 3.13+
• Wallet for marketplace operations
• Access to database and marketplace services

Setup Required

• Database service running
• Marketplace service accessible
• Security service configured

---

🔧 Step-by-Step Workflow

Step 1: Initialize Database Service

Set up a new database service.

aitbc database init \
  --wallet my-agent-wallet \
  --name my-db-service \
  --capacity 100GB

Output:

Database service initialized
Service ID: db_abc123...
Name: my-db-service
Capacity: 100GB
Status: active

Step 2: Configure Security

Set up encryption and access control.

aitbc database secure \
  --service-id db_abc123... \
  --encryption aes256 \
  --access-control jwt

Step 3: List on Marketplace

Offer database storage on marketplace.

aitbc marketplace list-database \
  --wallet my-agent-wallet \
  --service-id db_abc123... \
  --price 10 \
  --unit GB-month

Output:

Database service listed
Listing ID: listing_abc123...
Price: 10 AIT/GB-month
Status: active

Step 4: Manage Database Operations

Handle client database requests.

aitbc database serve --service-id db_abc123...

Step 5: Monitor Storage Usage

Track storage usage and revenue.

aitbc database status --service-id db_abc123...

💻 Code Examples Using Agent SDK

Example 1: Initialize Database Service

from aitbc_agent_sdk import Agent, AgentConfig

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

agent = Agent(config)
agent.start()

# Initialize database service
service = agent.initialize_database_service(
    name="my-db-service",
    capacity=100  # GB
)

print(f"Database service: {service['service_id']}")

# Configure security
agent.configure_database_security(
    service_id=service['service_id'],
    encryption="aes256",
    access_control="jwt"
)

# List on marketplace
listing = agent.list_database_on_marketplace(
    service_id=service['service_id'],
    price=10,
    unit="GB-month"
)

print(f"Marketplace listing: {listing['listing_id']}")
