Tor Relay Nodes
P2P InfrastructureVolunteer-operated network nodes implementing the Tor onion routing protocol, providing anonymous multi-hop routing for internet traffic through guard (entry), middle, and exit relay roles. Each relay peels one layer of encryption, ensuring no single node knows both the origin and destination of traffic.

P2P Infrastructure Atributos
P2P Architecture Onion routing (layered encryption, 3-hop circuit: guard → middle → exit)
Overlay Network Global (public relay directory maintained by directory authorities; bridges unlisted)
Content Addressing No (location-based routing, not content-addressed)
Local-First N/A (routing infrastructure; data passes through, not stored)
E2EE Yes — multi-layer onion encryption (each hop decrypts one layer; E2EE between client and exit for HTTPS traffic depends on application)
Byzantine Fault Tolerance No (probabilistic, not BFT; network trusts directory authority consensus)
Signature RSA-1024 (legacy) / Ed25519 (modern) — relay identity keys; TLS for transport
Permissions Exit policies (each relay operator configures exit policy rules); directory authority flags (Guard, Exit, Fast, Stable)
Infrastructure Function Anonymous routing; Censorship circumvention
Threat Model State-level censorship; Mass surveillance; Traffic analysis; DPI (Deep Packet Inspection); ISP-level blocking
Volunteer / Node Model Volunteer-operated (self-funded by operators); Hybrid (volunteer + foundation-operated bridges and some exit relays)
Traffic Visibility No content (encrypted payload only); No metadata between hops (each relay knows only previous and next hop, not origin and destination simultaneously)
Active Deployment Scale ~8,000 active relay nodes (July 2025); ~2,000 bridge relays; ~2.5M daily users; majority of traffic from Russia, Iran, USA
