Hubert

Infraestructura P2P

Asynchronous coordination service enabling Gordian Clubs, FROST signing ceremonies, and other multi-party cryptographic protocols to communicate via "dead-drops" without trusted servers or persistent connections. Provides write-once storage semantics where senders publish encrypted payloads at locations derived from ARIDs (Apparently Random Identifiers) — the storage network sees only HKDF-derived storage keys, never the ARIDs themselves. Backends include BitTorrent Mainline DHT (small messages, ~2hr persistence with hourly re-announcement), IPFS (large content up to 10MB via Kubo daemon, IPNS records), Hybrid (automatic size-based routing combining DHT speed with IPFS capacity), and Server (centralized for testing). All payloads encrypted via GSTP; reference encryption hides IPFS ARIDs from DHT observers. Released October 2025

Dominios de Caso de Uso

Evolución de Plataformas y Soberanía

Infraestructura P2P Atributos

Orígenes

Blockchain Commons; designed to enable autonomous coordination of cryptographic objects (Gordian Clubs, FROST ceremonies) without trusted infrastructure

Base de Datos

Backend-dependent — DHT (in-memory distributed), IPFS (Kubo daemon storage), Server (configurable centralized)

Formatos de Datos

Gordian Envelopes wrapped in GSTP (Gordian Sealed Transaction Protocol) encryption; CBOR (via dCBOR)

Soporte Móvil

Library-level — Rust libraries (hubert-rust, frost-hubert-rust) cross-compile to mobile; mobile-friendly given small message size on the DHT backend; no first-party mobile app yet

Soporte Web

Library-level — HTTP transport possible against IPFS Kubo and other backends; web bindings TBD

Aplicaciones Nativas

CLI tools — hubert-cli, FROST ceremony CLI demos

Términos

Open source, BSD-2-Clause Plus Patent License

Fondos

Unknown — funded under Blockchain Commons general operating budget; specific Hubert allocation not separately published

Basado En

Gordian Envelope; GSTP; ARIDs (Apparently Random Identifiers); HKDF (RFC 5869); BitTorrent Mainline DHT (BEP-44); IPFS / IPNS; Kubo

Arquitectura P2P

Layered service over existing P2P infrastructure (Mainline DHT and IPFS); not a new node network but a coordination semantics layer above them

Red de Superposición

BitTorrent Mainline DHT; IPFS DHT; Hybrid (automatic backend selection by size)

Direccionamiento por Contenido

ARID-derived storage keys (HKDF-derived from ARID; ARID never exposed to network); IPFS CIDs for large payloads with encrypted DHT references

Local-First

Yes — Hubert nodes can run locally; supports air-gapped publication and retrieval

Cifrado de Extremo a Extremo (E2EE)

Yes — all payloads GSTP-encrypted; reference encryption hides IPFS ARIDs from DHT observers; storage backends see only encrypted blobs

Tolerancia a Fallos Bizantinos

Inherits from underlying DHT/IPFS substrate; write-once semantics eliminate race conditions and ensure message immutability

Firma

Per-payload cryptographic signing via Envelope + GSTP; integrates with FROST threshold signatures

Permisos

ARID-based addressing — only parties knowing the ARID (out-of-band) can compute the storage location; permits in payload Envelopes provide further access control

Madurez del Protocolo / Estandarización

Alpha release Oct 2025; BCR-2025-006 specification; reference Rust implementation deployed

Función de Infraestructura

Asynchronous coordination service — write-once dead-drops for multi-party cryptographic protocol messages; query-addressable storage abstraction over diverse backends

Modelo de Amenazas

Untrusted storage networks; metadata privacy from DHT observers (ARIDs hidden via HKDF derivation; IPFS ARIDs hidden from DHT via reference encryption); does not provide forward secrecy for long-running conversations (would require ratcheting layered above)

Modelo de Nodo Voluntario

Inherits from underlying substrates — BitTorrent Mainline DHT (volunteer global network), IPFS (volunteer + paid pinning); Hubert itself is a client/library, not a separate node network

Visibilidad del Tráfico

Storage operators see encrypted blobs at HKDF-derived storage keys; ARIDs themselves never exposed; HTTPS for IPFS Kubo RPC

Escala de Despliegue Activo

Small — recently released; ecosystem in early adoption phase
