Use Case: Monitoring Swarm for Blockchain Security

Security monitoring is a natural fit for agent swarms. Multiple specialized agents watch for different threat patterns, coordinate findings, and trigger alerts when threats are detected.

The Challenge

Blockchain security requires:

• Continuous monitoring: Watching for suspicious activity 24/7
• Pattern detection: Identifying threats across multiple signals
• Rapid response: Alerting and responding to threats quickly
• Coordinated analysis: Multiple agents analyzing different aspects

This is exactly what agent swarms excel at.

Architecture

A security monitoring swarm with specialized agents:

• Event Monitor: Watches BlockWire for suspicious events
• Pattern Analyzer: Detects threat patterns in event data
• Risk Assessor: Evaluates threat severity
• Alert Coordinator: Manages alert delivery and escalation

Implementation

Event Monitor

Monitors BlockWire for suspicious events:

typescript
app.post('/blockwire/events', async (req, res) => {
  res.status(200).send('OK');
  
  for (const event of req.body.events) {
    // Check for suspicious patterns
    if (event.type === 'large_transfer' && event.data.usdValue > 100000) {
      await switchboard.tasks.create({
        swarmId: 'security-swarm',
        type: 'analyze_transfer',
        payload: event,
        priority: 2, // High priority
      });
    }
    
    if (event.type === 'liquidity_removed' && isSignificant(event)) {
      await switchboard.tasks.create({
        swarmId: 'security-swarm',
        type: 'analyze_liquidity',
        payload: event,
        priority: 3, // Critical
      });
    }
  }
});

Pattern Analyzer

Analyzes events for threat patterns:

typescript
async function analyzeThreat(task) {
  const analysis = await performAnalysis(task.payload);
  
  if (analysis.threatLevel > THRESHOLD) {
    // Create risk assessment task
    await switchboard.tasks.create({
      swarmId: 'security-swarm',
      type: 'assess_risk',
      payload: {
        event: task.payload,
        analysis: analysis,
      },
      priority: analysis.threatLevel,
    });
  }
  
  await switchboard.tasks.complete({ taskId: task.id });
}

Risk Assessor

Evaluates threat severity and triggers alerts:

typescript
async function assessRisk(task) {
  const risk = await evaluateRisk(task.payload);
  
  if (risk.severity === 'critical') {
    // Broadcast critical alert
    await switchboard.messages.broadcast({
      swarmId: 'security-swarm',
      agentId: 'risk-assessor',
      message: {
        type: 'CRITICAL_ALERT',
        threat: risk.description,
        recommendation: risk.action,
      },
    });
  }
  
  // Update shared state
  await switchboard.state.set({
    swarmId: 'security-swarm',
    key: `threat:${task.payload.event.txHash}`,
    value: risk,
  });
}

Why This Works

This architecture provides:

• Specialized agents: Each agent focuses on one aspect of security
• Coordinated analysis: Agents work together through task queues and messaging
• Priority handling: Critical threats get processed first
• Scalable: Add more analyzers as threat volume grows

Extensions

Extend this pattern:

• Add historical analysis agents
• Add automated response agents
• Add reporting agents for compliance
• Add integration with external security systems

Security monitoring is a perfect use case for agent swarms. The coordination infrastructure handles the complexity, agents focus on detection and analysis.
