PouchDB

Protocolo de Datos Descentralizado

An open-source JavaScript database inspired by Apache CouchDB, designed to run inside the browser so that web applications work as well offline as online. Applications store JSON documents in a local database; PouchDB replicates them, in either direction and continuously if wanted, with CouchDB or any server that speaks the CouchDB replication protocol, and resolves conflicts using CouchDB's revision model. It is not a self-contained storage engine but a CouchDB-style layer over other stores: by default it uses IndexedDB in the browser and LevelDB in Node.js, with other adapters available. The project is currently an Apache Software Foundation Incubator podling .

Protocolo de Datos Descentralizado Atributos

Orígenes Offline-first web development: bring CouchDB's sync model into the browser so developers can build applications that keep working without a connection and sync when they reconnect
Base de Datos Not a storage engine: a CouchDB-style layer over IndexedDB in browsers and LevelDB in Node.js, with additional adapters for other backends
Lenguaje de Consulta Map/reduce queries, plus Mango selector queries through the separate pouchdb-find plugin, following CouchDB (both appear in the PouchDB API reference)
Formatos de Datos JSON documents with revision identifiers and attachments, matching CouchDB's document model
Edición Colaborativa en Vivo Partial: documents replicate continuously and conflicts are detected through revision trees and resolved by the application or the winning-revision rule; there is no character-level collaborative editing
Edición de Texto Enriquecido Not stated by the project.
Soporte Móvil Yes, through web views and JavaScript runtimes (the project runs in mobile browsers and hybrid-app frameworks)
Soporte Web Yes: designed to run in the browser, with IndexedDB by default
Aplicaciones Nativas Via embedding in Electron, Node.js and hybrid-app frameworks; not a native library
Términos Free and open source (Apache-2.0)
Fondos Not stated by the project.
Basado En Apache CouchDB's document model, MVCC and replication protocol; the CouchDB project defines the protocol PouchDB speaks
Arquitectura P2P Replication endpoints rather than a peer-to-peer network: any two PouchDB or CouchDB databases can replicate with each other over the CouchDB HTTP protocol, so a client can sync with a server or with another client that exposes the protocol; there is no discovery or relay layer
Red de Superposición None: replication is between named databases over HTTP
Direccionamiento por Contenido No: documents are keyed by identifier and revision, and revisions carry hash-based ids, but content is not addressed by hash
Local-First Local-First: the browser database is a full replica that works offline and syncs when connected
Cifrado de Extremo a Extremo (E2EE) No: PouchDB does not encrypt documents itself; encryption is left to plugins or the application
Biblioteca de CRDTs No: it uses CouchDB's revision-tree conflict model rather than CRDTs
Tolerancia a Fallos Bizantinos No: replication trusts the peer's database and its own authorisation; no Byzantine defence is described
Firma N/A: documents are not signed; authentication is HTTP-based at the server
Permisos Server-side: access control is delegated to CouchDB-compatible servers (database and document-level validation); PouchDB local databases have no permission model
Compatibilidad con la Web Semántica N/A: JSON document store with no RDF layer
Contrato Inteligente N/A: no ledger or contract component
Posición en la Pila del Protocolo Application-layer: a JavaScript library over HTTP/1.1 replication and local browser storage
Incorporación de Activos/Valor None: no token or value-transfer mechanism
Madurez del Protocolo / Estandarización Mature library (version 9) implementing the documented CouchDB replication protocol; the ASF incubation signals a formal governance transition rather than a specification change
