README

Open-source, cross-platform VPN client built with Rust that provides true privacy through decentralized mixnet technology and multi-hop censorship-resistant WireGuard tunneling.

# 🚀 What is NymVPN

NymVPN is a privacy-focused, decentralized VPN application that goes beyond traditional VPNs by leveraging:

- 🔀 [Mixnet](https://nym.com/mixnet) Technology: Anonymous 5-hop routing through Nym's decentralized network
- ⚡ WireGuard + AmneziaWG: Fast, secure tunneling with built-in censorship resistance
- 🛡️ Metadata Protection: Unlike traditional VPNs, protects both content AND traffic patterns (in mixnet mode)
- 🔐 Zero-Knowledge Credentials: Private authentication using zero-knowledge [zk-nyms](https://nym.com/zk-nyms)
- 🌍 No Single Point of Failure: Fully decentralized infrastructure

# ✨ Key Features

🎯 Dual-Mode Privacy Architecture

- Anonymous Mode (5-hop mixnet): Maximal anonymity thanks to Nym's Noise Generating Mixnet with added noise to protect users against even AI surveillance
- Fast Mode (2-hop WireGuard): Decentralized 2-hop mode for faster connections and less latency thanks to WireGuard

🔧 Developer-Friendly

- 100% Open Source: Fully auditable codebase
- Rust-based: Memory-safe, high-performance implementation
- Cross-platform: Android, iOS, Linux, macOS, Windows, CLI

⚙️ Power User Features

- Split Tunneling: Choose per-app routing (mixnet vs WireGuard) (_coming soon_)
- Custom Entry/Exit Selection: Choose your preferred node operators
- Kill Switch: Automatic connection protection with data leak prevention
- Multi-language Support: 10+ localizations with crowdsourced language support

🛡️ Advanced Privacy and Security

- Multi-hop by Default: No server views both your IP address and online activity
- zk-nyms: Private zero-knowledge credential system to unlink payments data from online activity
- No Centralized Logging: Cryptographically impossible to track users
- Advanced Cryptographic Stack: Cure25519, AES, ChaCha20-Poly1305, BLAKE2/BLAKE3, Lioness Wide Block Cipher, Pointcheval-Sanders Signatures, Pedersen Commitments, NIZK Proofs, BLS12-381 Curve, post-quantum readiness (_coming soon_)
- Independent Security Audits: JP Aumasson (2021), Oak Security (2022), Cryspen (2023-2024), Cure53 (2024)

🌐 Censorship Resistance Technologies

- AmneziaWG Integration: Bypass barriers to information access with AmneziaWG (censorship-resistance WireGuard fork)
- Adaptive Protocols: Pluggable transport, QUIC (_coming soon_)
