PKARR

Protocolo P2P

Public Key Addressable Resource Records — converts an Ed25519 keypair into a self-controlled "domain": DNS-style records (A/AAAA/TXT/CNAME) are signed and published as BEP44 mutable items on the BitTorrent Mainline DHT, resolvable anywhere without registrars or platforms. HTTP-to-DHT relay gateways bridge browser and UDP-restricted clients to the DHT. Built directly on the existing BitTorrent Mainline DHT (P2P Infra) rather than new infrastructure — leverages a 15+ year-old, ~10M+ node network. Serves as the discovery/naming layer under Pubky Core's homeserver architecture. [b]

Protocolo P2P Atributos

Orígenes Distributed naming / identity — reusing BitTorrent's existing Mainline DHT as a "sovereign TLD" substrate instead of building new discovery infrastructure or depending on DNS registrars
Base de Datos N/A (records are ephemeral DHT entries, not persistent storage — BEP44 mutable items with hour-scale retention requiring periodic republishing)
Lenguaje de Consulta N/A (DHT lookup by public key, not a query language)
Formatos de Datos Signed DNS-style records (A, AAAA, TXT, CNAME) as BEP44 mutable DHT items, 1000-byte size limit
Edición Colaborativa en Vivo N/A
Edición de Texto Enriquecido N/A
Soporte Móvil Yes (JS/WASM bindings support mobile web/hybrid contexts; used by Pubky Core's mobile SDK)
Soporte Web Yes (@synonymdev/pkarr JS/WASM bindings; pkdns.net web resolver demo)
Aplicaciones Nativas Yes (Rust core library embeddable in native apps)
Términos Free / open protocol; relay operators may charge, but self-relaying is possible
Fondos Undisclosed
Basado En BitTorrent Mainline DHT (P2P Infra — specifically BEP44, the arbitrary mutable-data storage extension, rather than new infrastructure); Ed25519 signing
Arquitectura P2P Kademlia DHT (inherited from Mainline DHT); PKARR does not run a separate overlay — it publishes into the existing BitTorrent DHT
Red de Superposición Reuses the existing global BitTorrent Mainline DHT overlay rather than establishing its own
Direccionamiento por Contenido Partial — records addressed by the owning Ed25519 public key (key-addressed, not content-hash-addressed)
Local-First N/A (naming/discovery layer, not a data-storage system)
Cifrado de Extremo a Extremo (E2EE) No (DHT records are signed for authenticity, not encrypted for confidentiality)
Biblioteca de CRDTs N/A
Tolerancia a Fallos Bizantinos Inherits Mainline DHT's probabilistic resilience — no formal BFT consensus
Firma Ed25519 (keypair signs each DNS-style record packet)
Permisos Key-holder-only write access — only the corresponding Ed25519 private key can publish/update a given record
Compatibilidad con la Web Semántica N/A (DNS-style records, not RDF/Linked Data)
Contrato Inteligente N/A
Posición en la Pila del Protocolo Discovery/naming layer beneath application protocols — Pubky Core's homeserver discovery mechanism sits directly on PKARR
Incorporación de Activos/Valor N/A
Madurez del Protocolo / Estandarización No formal standards-body process; single-maintainer (Pubky/Synonym) reference implementation, v8.0.0, actively released and maintained
