I2P

Infraestructura P2P

The Invisible Internet Project — an anonymous, censorship-resistant overlay network layer implementing garlic routing (a variant of onion routing). Every I2P router participates in routing for others, using unidirectional tunnel pairs and a distributed Kademlia DHT network database. Designed for internal darknet communication (.i2p sites, email, torrents) rather than clearnet outproxying.

Capacidades

Autoalojable Cifrado de extremo a extremo

Infraestructura P2P Atributos

Orígenes Freenet/Hyphanet (fork); IIP (Invisible IRC Project); mix network research; Kademlia DHT
Base de Datos Kademlia-based distributed network database (netDb) for routing metadata; no application-layer data store
Formatos de Datos I2NP (I2P Network Protocol) messages; arbitrary application data encapsulated in garlic messages
Soporte Móvil No (desktop daemon; web console at localhost:7657)
Soporte Web Yes (web console interface accessible locally)
Aplicaciones Nativas Yes (Java router for Linux/macOS/Windows; i2pd C++ variant; Android via i2pd-android)
Términos Free (donation-funded; core project does not solicit donations directly)
Fondos Unknown (donation amounts not publicly disclosed; OTF support amount undisclosed)
Basado En Freenet (censorship-resistant storage concept); Kademlia DHT; mix network research; garlic routing extends onion routing
Arquitectura P2P Garlic routing (unidirectional tunnel pairs; packet-switched; multiple messages bundled per garlic); Kademlia DHT for peer discovery
Red de Superposición Global (self-organizing network database; no central directory servers; rotating floodfill routers maintain netDb)
Direccionamiento por Contenido No (router-identity-addressed, not content-addressed; application-layer content addressing possible)
Local-First N/A (routing infrastructure; data transits encrypted tunnels, not stored at network layer)
Cifrado de Extremo a Extremo (E2EE) Yes — three layers: garlic encryption (message delivery verification), tunnel encryption, inter-router transport encryption
Tolerancia a Fallos Bizantinos No (reputation-based peer selection; no Byzantine fault tolerant consensus)
Firma ElGamal/ECIES (encryption); Ed25519/DSA (signatures); X25519 (key exchange in ECIES-X25519 mode)
Permisos N/A (open routing; all I2P routers contribute to network)
Madurez del Protocolo / Estandarización Community Standard (open specification, published protocol docs; no formal standards body)
Función de Infraestructura Anonymous routing; Censorship circumvention (internal darknet focus)
Modelo de Amenazas Mass surveillance; Traffic analysis; Targeted surveillance; Metadata exposure
Modelo de Nodo Voluntario Volunteer-operated (every I2P router automatically routes for others; no dedicated relay class)
Visibilidad del Tráfico No content (three-layer encryption); No metadata (unidirectional tunnels mean each router sees only previous/next hop)
Escala de Despliegue Activo ~55,000 router nodes worldwide (Wikipedia/research, as of 2024-2025)
