# The Technology Behind ThePublic's Mesh Network
ThePublic's decentralized WiFi network represents a significant innovation in internet infrastructure. In this technical deep dive, we'll explore the architecture, protocols, and systems that make our network possible.
Network Architecture Overview
At its core, ThePublic is a sophisticated mesh network with blockchain-based incentives and governance. The network consists of several key components:
1. Node Hardware
Our network relies on two types of nodes:
#### Standard Nodes - Raspberry Pi 4 (or equivalent) with 4GB+ RAM - Dual-band WiFi 6 capable network interfaces - Optional: Directional antennas for extended range - Power consumption: 5-10W (can be solar-powered)
#### Gateway Nodes - Higher capacity hardware with 8GB+ RAM - Gigabit ethernet backhaul connection - Enhanced cooling systems for 24/7 operation - Supports up to 200 simultaneous connections
Both node types run our custom Linux distribution, PublicOS, which handles routing, security, and blockchain interactions.
2. Mesh Networking Protocol
We've developed a modified version of the B.A.T.M.A.N. Advanced (Better Approach To Mobile Ad-hoc Networking) protocol that incorporates:
- Dynamic route optimization based on network conditions
- Load balancing across multiple paths
- QoS (Quality of Service) prioritization for different traffic types
- Automatic failover when nodes go offline
This creates a self-healing network that can adapt to changing conditions and node availability.
Blockchain Integration
ThePublic uses a purpose-built blockchain to handle:
1. Node Registration and Identity
Each node generates a unique cryptographic identity when it joins the network. This identity: - Prevents Sybil attacks through hardware attestation - Builds reputation over time based on performance - Enables secure and anonymous authentication
2. Micropayment Channels
Our network uses state channels for efficient micropayments: - Users can pre-fund accounts for seamless connectivity - Node operators receive compensation in near real-time - Only settlement transactions hit the main blockchain - Transaction fees are kept below 0.1% of transferred value
3. Consensus Mechanism
We employ a Proof of Coverage consensus mechanism that: - Verifies node locations and coverage claims - Rewards honest reporting and penalizes false claims - Operates with minimal energy consumption - Achieves finality in under 3 seconds
Security Architecture
Security is paramount in a decentralized network. Our approach includes:
1. Encrypted Traffic
All data passing through ThePublic is encrypted using: - WPA3 for client connections - Wireguard tunnels between nodes - Optional end-to-end encryption for sensitive applications
2. Threat Detection
Our distributed threat detection system: - Identifies anomalous traffic patterns - Blocks known malicious actors - Prevents DDoS attacks through traffic dispersion - Isolates compromised nodes automatically
3. Privacy Preservation
We've designed the network to maximize user privacy: - No logging of browsing history - IP address rotation - Onion routing option for enhanced anonymity - Zero-knowledge proofs for authentication without identification
Performance Optimizations
To deliver a seamless user experience, we've implemented several performance enhancements:
1. Edge Caching
Popular content is cached at the edge of the network: - Reduces latency for frequently accessed resources - Decreases backhaul bandwidth requirements - Updates automatically as content changes - Respects cache control headers
2. Adaptive Bandwidth Management
Our network dynamically allocates bandwidth: - Prioritizes real-time applications during congestion - Implements fair usage policies automatically - Provides burst capacity when available - Degrades gracefully under heavy load
3. Predictive Scaling
The network anticipates demand increases: - Analyzes historical usage patterns - Activates standby nodes during peak hours - Redirects traffic to optimize path efficiency - Notifies operators of capacity constraints
Future Technical Roadmap
We're continuously evolving ThePublic's technology. Upcoming developments include:
- **Multi-spectrum Support**: Expanding beyond WiFi to include CBRS and TV whitespace frequencies 2. **AI-Powered Optimization**: Using machine learning to predict network issues before they occur 3. **IoT Integration**: Specialized protocols for low-power IoT devices 4. **Satellite Backhaul**: Partnerships with LEO satellite providers for truly remote areas 5. **Quantum-Resistant Cryptography**: Future-proofing our security systems
Developer Resources
For those interested in building on or contributing to ThePublic:
- Our core protocols are open-source and available on GitHub
- We offer a comprehensive API for developing applications on the network
- Developer grants are available for projects that enhance the network
- Regular hackathons focus on solving specific network challenges
By combining cutting-edge wireless technology with blockchain incentives and community governance, ThePublic is creating a new model for internet infrastructure—one that's more resilient, accessible, and equitable than traditional approaches.
