A serverless, cryptographically secure peer-to-peer network — written in Go.

Inspired by the Nerve (2016) concept:
every device is both a client and a server.
No central servers. No rendezvous point.
A fully decentralized network where peers discover, authenticate, and communicate directly.

P2P-Park is an exploration of production-grade distributed systems, applied cryptography, and peer-to-peer networking — designed to grow into a platform capable of double-ratchet DMs, secure group chats, and eventually MLS-style large-scale group messaging.

Actively in development.
Implementing a Kademlia-like DHT

A fully encrypted transport layer built on the Noise Protocol Framework.

• Handshake pattern: Noise_XX_25519_ChaChaPoly_BLAKE2s
• Mutual authentication during handshake
• Identity payloads exchanged during connection establishment
• All traffic encrypted via length-prefixed ChaCha20-Poly1305 frames
• Resistant to MITM for authenticated peers

The transport layer alone is suitable for real-world secure messaging systems.

P2P-Park cleanly separates:

• X25519 Noise static keypair
• Defines the network address of a peer
• Used for routing, peer uniqueness, and connection authentication

• ed25519 signing keypair
• Used for:
  • user profiles
  • signed state (e.g., points module experiments)
  • future message-level signatures
• Exchanged via an /identify message immediately post-handshake

For reviewers and hiring managers, the repository highlights:

• Hand-rolled Noise_XX handshake
• Identity payload binding
• Proper use of X25519 + ChaChaPoly + BLAKE2s

• Network abstraction
• Peer state tracking
• Duplicate-connection resolution
• Typed gossip message routing

• Layered architecture (transport → identity → app protocol)
• Extensible message schema
• Separation of user identity vs device identity
• Pluggable encrypted channels
