Nysiris

Nysiris is a private browser for the Nym mixnet: a cross-platform client (web / PWA / Android / desktop) plus the pieces to host your own service on the mixnet. It gives you a calm, everyday UI — private links, a community timeline with end-to-end encrypted DMs, and a leak-guarded tunnel — while the mixnet hides who talks to whom and when from network observers. Formerly fly-protocol; renamed, nothing else moved.

Features

Nym Mixnet Integration: Routes all network traffic via the Nym mixnet using Sphinx packet formats, effectively hiding identity, IP address, and communication timing against metadata and network analysis.
Single-Use SURBs (Anonymous Replies): Host services and peers never learn client IP or mixnet addresses. Replies return securely using Single-Use Reply Blocks.
Cover Traffic & Chaumian Mixing: Shields against traffic analysis by injecting noise/cover traffic into the network.
Decentralized Portal System: Inspired by the concept of the legacy Osiris Portal System. Build and run independent, self-hosted web portals, blogs, and forums
No Central Server / Single Point of Failure: Sites live natively on the peer network. You maintain full data ownership and dictate host access.
P2P & Hidden Services: Reachable directly via mixnet addresses (e.g., nym://...) without needing traditional web hosting or DNS.
Metadata-Minimal Timelines & Forums: Threaded discussions and social feeds designed with minimal metadata footprint.
End-to-End Encrypted DMs: Direct messaging protected with E2EE, local attachment encryption, and petnames/trust indicators.
Modular P2P Transport (nysiris-core): High-performance, modular networking stack written in Rust.
Zero-Install Web PWA: Accessible straight from modern web browsers via progressive web application (React/Rust web components).
Native Desktop Apps: High-performance, lightweight binaries available for Linux and Windows.
Self-Hosting Service Provider: Spin up custom social/echo services with a single terminal command (SP_DATA_DIR=... cargo run).
Apache-2.0 License: Open source and community-driven.
Offline-Friendly Verification: Built-in verification tooling ensuring core logic can be tested locally without network access.
