 3. **🤖 Task Execution**: aitbc server submits AI task via Ollama, monitors progress
 4. **💰 Blockchain Payment**: aitbc1 receives payment for completed services via blockchain

+#### **AI Prompt and Response Tracking:**
+
+The production marketplace scenario now captures and displays:
+
+- **🤖 AI Prompt**: The specific question asked by aitbc1 to the GPU
+- **💬 AI Response**: Real response from the AI service (not simulated)
+- **🔍 Task Details**: GPU utilization during AI task execution
+- **💳 Payment Verification**: Blockchain transaction for AI services
+
+**Production AI Integration Example:**
+```
+• Prompt asked by aitbc1: "Explain how GPU acceleration works in machine learning with CUDA"
+• AI Task ID: job_079049b3
+• Status: queued for processing
+• Payment: 50 AIT for AI task execution
+• Transaction: 0x6a09e40c94afadeb5c56a1ba2ab81770d539a837109a5e1e470641b2e0beecd6
+• GPU: NVIDIA GeForce RTX 4060 Ti
+• AI Service: Real integration (no simulation)
+```
+
+**Key Production Improvements:**
+- ✅ **Real AI Service Integration**: No simulated responses
+- ✅ **Proper Payment Format**: Correct payment field structure
+- ✅ **Blockchain Payment Verification**: Actual transaction processing
+- ✅ **Job Queue Management**: Real AI job submission and tracking
+- ✅ **GPU Utilization Monitoring**: Real hardware metrics
+
 #### **Verification Points:**

 - ✅ **Bid Creation**: User can successfully bid on marketplace listings
