Conduit (Psiphon)

Infraestructura P2P

A volunteer-operated proxy relay application within the Psiphon censorship circumvention network. Volunteers outside censored countries install Conduit on Android, desktop, or server to share bandwidth as proxy nodes. Censored users (primarily in Iran) connect through Psiphon, which routes their traffic through available Conduit nodes via the inproxy protocol, forwarding it to Psiphon's cloud server network and onward to the open internet.

Infraestructura P2P Atributos

Orígenes Psiphon 1.0 (Citizen Lab, University of Toronto, 2006); Psiphon 1.X volunteer home-based proxy model; inproxy protocol from psiphon-tunnel-core
Base de Datos N/A (relay infrastructure; reputation data stored locally for broker matching)
Formatos de Datos Arbitrary (application-agnostic; forwards encrypted Psiphon tunnel traffic)
Soporte Móvil Yes (Android via Google Play)
Soporte Web No (no web interface)
Aplicaciones Nativas Yes (Android app; macOS via Catalyst; CLI binary for Linux/macOS/Windows)
Términos Free (volunteer bandwidth donation; no compensation to Conduit operators)
Fondos $18.54M+ OTF awards for 2024 (cumulative Psiphon funding from US State Dept, OTF, BBC in hundreds of millions since 2010)
Basado En Psiphon 1.X volunteer home-proxy concept; SSH tunneling; VPN/HTTPS/proxy obfuscation stack; inproxy protocol
Arquitectura P2P Centrally brokered volunteer proxy (inproxy): censored users matched to available Conduit volunteer nodes by Psiphon broker; traffic relayed via encrypted tunnel to Psiphon cloud servers
Red de Superposición N/A (traffic forwarded to Psiphon cloud; no content-addressing)
Direccionamiento por Contenido N/A
Local-First N/A (relay only; data passes through, not stored)
Cifrado de Extremo a Extremo (E2EE) Yes — SSH core tunnel with obfuscation; encrypted between Psiphon client and Psiphon server; Conduit node sees only encrypted proxy traffic
Tolerancia a Fallos Bizantinos No
Firma SSH public keys (pre-shared for server authentication); obfuscation keys
Permisos Broker reputation system (nodes build reputation by uptime; broker preferentially routes to established nodes)
Madurez del Protocolo / Estandarización Proprietary Open Standard (Psiphon inproxy protocol is open source but Psiphon-controlled; no formal standards body)
Función de Infraestructura Censorship circumvention; Relay / proxy; Bandwidth sharing
Modelo de Amenazas State-level censorship; DPI (Deep Packet Inspection); ISP-level blocking; IP enumeration blocking
Modelo de Nodo Voluntario Volunteer-operated (bandwidth donation); Hybrid (volunteer Conduit nodes + Psiphon commercial cloud servers)
Visibilidad del Tráfico No content (encrypted payload only); Partial metadata — Conduit node sees encrypted traffic from matched user; does not see browsing history or content
Escala de Despliegue Activo 200,000+ Conduit stations activated January 2026 (Iran-focused deployment surge); ~3M+ weekly Psiphon users globally
