Willow

Protocolo de Datos Descentralizado

A family of specifications for P2P data stores enabling fine-grained, private data sharing, where data is organized into namespaces with path-based hierarchies and synced between peers using a range-based set reconciliation protocol

Dominios de Caso de Uso

Evolución de Plataformas y Soberanía

Protocolo de Datos Descentralizado Atributos

Orígenes

Ecosystem/SDK

Base de Datos

Custom (3D data model: namespace × subspace × path with time-stamped entries; append-only per subspace-path)

Lenguaje de Consulta

Custom (area-based queries over namespace/subspace/path/time ranges)

Formatos de Datos

Custom (Willow entries are metadata + opaque payloads; payload format is application-defined)

Edición Colaborativa en Vivo

N/A (protocol layer; provides eventual consistency primitives but not editor-level collaboration)

Edición de Texto Enriquecido

N/A (specification/protocol layer only)

Soporte Móvil

N/A (specification; implementations can target mobile)

Soporte Web

N/A (specification; implementations can target web)

Aplicaciones Nativas

N/A (specification only)

Términos

Self-hosting

Fondos

Undisclosed (NLnet grant amounts)

Basado En

Original (inspired by Earthstar's data model but fully redesigned)

Arquitectura P2P

Mesh network (peer-to-peer sync using WGPS — Willow General Purpose Sync protocol)

Red de Superposición

Store-wide (sync is scoped to shared namespaces between peers)

Direccionamiento por Contenido

Yes (entries reference payloads by hash digest; supports pluggable hash functions)

Local-First

Local-First (data resides on user devices; sync is opportunistic between peers)

Cifrado de Extremo a Extremo (E2EE)

Yes (Meadowcap capability system enables private data sharing; payloads can be encrypted to authorized readers)

Biblioteca de CRDTs

N/A (uses "prefix pruning" — newer entries on same subspace+path supersede older ones — rather than CRDTs)

Tolerancia a Fallos Bizantinos

No (trusts authorized writers within a namespace; no global BFT consensus)

Firma

Ed25519 (default; pluggable signature scheme via Meadowcap)

Permisos

Cryptographic Capabilities (Meadowcap: delegatable read/write capabilities scoped to areas of the data space)

Compatibilidad con la Web Semántica

N/A

Contrato Inteligente

Posición en la Pila del Protocolo

Application-layer (built on TCP/IP)

Incorporación de Activos/Valor

None — Willow is a sync protocol specification with no native token or economic layer. Derived from the Earthstar lineage, which is explicitly volunteer/cooperative. Node operation is incentivized by mutual benefit rather than cryptoeconomics.

Madurez del Protocolo / Estandarización

Proprietary Open Standard (detailed published specification at willowprotocol.org; developed by Earthstar Project; not submitted to formal standards body)
