+# 3Nodes
+
+3Nodes are physical computing hardware (servers, computers) that can be bought and sold within the TF Marketplace using TFP. Users can purchase 3Nodes in two distinct ways: either hosted by the supplier or physically transferred to the buyer.
+
+## Core Principles
+
+- **Hardware Exchange**: Direct marketplace for physical computing equipment
+- **Sovereignty**: Buyers gain full ownership of purchased hardware
+- **Fair Pricing**: Market-driven pricing with transparency
+- **TFP-Based**: All transactions conducted using TFP
+- **Quality Assurance**: Hardware specifications verified and rated
+- **Flexible Ownership**: Options for hosted or physically transferred hardware
+- **Upfront Payments**: One-time TFP payment for both ownership models
+
+## How It Works
+
+### For Sellers
+
+- **Hardware Registration**:
+  - Register available hardware with detailed specifications
+  - Upload verification photos and documentation
+  - Set pricing in TFP
+  - Define shipping options and costs
+
+- **Listing Management**:
+  - Update hardware availability
+  - Modify pricing based on market conditions
+  - Respond to buyer inquiries
+  - Track sales and shipping
+
+### For Buyers
+
+- **Hardware Discovery**:
+  - Browse available 3Nodes with filtering options
+  - Compare specifications and pricing
+  - Review seller ratings and history
+  - Ask questions about specific hardware
+
+- **Purchase Options**:
+  - **Option 1: Supplier-Hosted 3Nodes**
+    - Buy the 3Node with upfront TFP payment but have it hosted in the supplier's facility
+    - Maintain ownership while the supplier handles physical maintenance
+    - Revenue sharing model where the hoster (who is also the seller) gets part of the farming revenue
+    - Hoster/seller defines the revenue share percentage
+    - Ideal for buyers without suitable hosting facilities
+  
+  - **Option 2: Physical Transfer**
+    - Buy the 3Node with upfront TFP payment and have it physically shipped to your location
+    - Complete physical control and responsibility for the hardware
+    - Suitable for buyers with their own hosting capabilities
+
+- **Purchase Process**:
+  - Select desired 3Node and purchase option (hosted or transferred)
+  - Pay upfront using TFP for either option
+  - For physical transfer: arrange shipping and delivery
+  - For hosted option: receive access credentials
+  - Verify functionality and condition
+
+## Hardware Specifications
+
+3Nodes can include various types of computing hardware:
+
+- **Servers**: Enterprise-grade rack servers
+- **Desktop Computers**: Repurposed or custom-built desktops
+- **Mini PCs**: Compact computing devices
+- **Custom Builds**: Purpose-built hardware for TF Grid farming
+
+Each listing includes detailed specifications:
+
+- CPU type and core count
+- Memory capacity and type
+- Storage capacity and type
+- Network interfaces
+- Power consumption
+- Physical dimensions
+- Age and condition
+
+## TFP Exchange Mechanism
+
+- **Suppliers**: Hardware owners selling their equipment
+- **Consumers**: Users looking to acquire physical computing hardware
+- **Exchange Process**:
+  - **For Physically Transferred Hardware**:
+    - TFP transferred from buyer to seller upon purchase agreement
+    - Escrow system protects both parties during shipping
+    - Final release upon confirmed delivery and verification
+  
+  - **For Supplier-Hosted Hardware**:
+    - Upfront TFP payment to secure ownership
+    - Revenue sharing agreement between buyer and hoster/seller
+    - Hoster defines and receives a portion of farming revenue
+    - Clear SLAs define uptime and performance guarantees
+
+## Benefits
+
+- **Direct Exchange**: No intermediaries between hardware sellers and buyers
+- **Ecosystem Growth**: Facilitates expansion of the TF Grid through hardware redistribution
+- **Resource Optimization**: Gives new life to underutilized hardware
+- **Sovereignty**: Buyers gain full ownership of their hardware, regardless of hosting location
+- **Flexibility**: Choose between hosted or physically transferred hardware based on needs
+- **Community Building**: Connects hardware providers with potential farmers
+
+## Integration with TF Grid
+
+- Hardware purchased can be registered as farming nodes
+- Seamless pathway to becoming a resource provider
+- Technical support available for setting up purchased hardware
+- Community resources for optimizing hardware performance

+## Hosting vs. Physical Transfer Comparison
+
+| Aspect | Supplier-Hosted | Physical Transfer |
+|--------|----------------|-------------------|
+| **Physical Location** | Supplier's facility | Buyer's location |
+| **Payment Model** | Upfront TFP payment | Upfront TFP payment |
+| **Revenue Sharing** | Yes - hoster gets portion of farming revenue | No - buyer keeps 100% of farming revenue |
+| **Maintenance** | Handled by supplier | Buyer's responsibility |
+| **Power & Cooling** | Provided by supplier | Buyer's responsibility |
+| **Internet Connectivity** | Provided by supplier | Buyer's responsibility |
+| **Physical Access** | Limited or none | Complete |
+| **Setup Complexity** | Minimal (handled by supplier) | Buyer must set up |
+| **Best For** | Users without hosting facilities | Users with hosting capabilities |
