A comprehensive learning project exploring libp2p (peer-to-peer networking library) implementations across different programming languages. This repository serves as both a learning resource and a practical implementation showcase for building distributed, decentralized applications.
libp2p is a modular system of protocols, specifications, and libraries that enable the development of peer-to-peer network applications. This project demonstrates:
- P2P Node Creation: Building singular nodes that can join peer-to-peer networks
- Multi-transport Support: TCP, UDP (QUIC), and WebSocket connectivity
- Advanced Features: Hole punching, NAT traversal, DHT routing, relay services
- Scalability: Handling many simultaneous connections
- Real-world Protocols: Custom application-level protocols (Ping, Chat, Echo)
The Go implementation is complete and fully functional. Navigate to the libp2p-go/ directory for detailed setup instructions.
cd libp2p-go/
make build
make run-exampleKey Features:
- TCP, UDP (QUIC), WebSocket transports
- DHT-based peer discovery and data storage
- Circuit relay for NAT traversal
- Hole punching with DCUtR protocol
- AutoNAT for automatic NAT detection
- Comprehensive test suite with deterministic behavior
- Docker support for containerized deployment
- CLI interface with Cobra
- Structured logging with Logrus
The Rust implementation is planned and will provide similar functionality using the Rust libp2p ecosystem.

# Setup instructions coming soon...Both implementations emphasize deterministic testing:
- Event-driven synchronization instead of arbitrary time delays
- Channel-based coordination for reliable test execution
- Comprehensive integration tests covering real-world scenarios
- Race condition detection for concurrent operations
