Tahoe-LAFS

Rede de Armazenamento Descentralizada

Free and open-source decentralized file store built on a 'principle of least authority' (POLA) security model, providing provider-independent security: files are client-encrypted and erasure-coded (default 3-of-10) before distribution across storage servers, such that no server operator can read or modify user data.

Rede de Armazenamento Descentralizada Atributos

Origens Online backup / privacy-preserving cloud storage
Banco de Dados Distributed key-value store (erasure-coded shares across storage nodes; ACID-like via lease management)
Linguagem de Consulta REST/HTTP API; SFTP; FUSE filesystem mount
Formatos de Dados Any binary files and directories; mutable and immutable file types
Suporte Móvel Partial Mobile support (no native mobile app; web interface accessible via mobile)
Suporte Web Yes (HTTP web interface via gateway)
Aplicativos Nativos N/A (CLI + web API; no dedicated desktop app)
Termos Self-hosting (deploy own storage grid; federated volunteer grids possible)
Fundos N/A (volunteer project; no known external funding)
Baseado Em Novel (original architecture; no blockchain; uses Foolscap/HTTPS protocol)
Arquitetura P2P Mesh network (client connects to introducer, then to storage nodes; no routing protocol between nodes)
Rede de Sobreposição Store-wide (data limited to configured storage grid)
Endereçamento por Conteúdo Yes (immutable files addressed by content hash embedded in read capability)
Local-First N/A (client-server model; gateway on local machine or remote)
Criptografia de Ponta a Ponta (E2EE) Yes (client-side AES encryption before upload; storage servers never see plaintext)
Tolerância a Falhas Bizantinas Partial (erasure coding tolerates node failure; cryptographic proofs prevent silent data corruption; no Byzantine consensus protocol)
Assinatura Ed25519 (mutable file signatures)
Permissões Cryptographic Capabilities (read caps, write caps, verify caps — capability-based access control; no ACLs)
Compatibilidade com a Web Semântica N/A
Contrato Inteligente No
Posição na Pilha de Protocolo Application-layer (built on TCP/IP)
Incorporação de Ativo / Valor None (no token; volunteer or self-hosted model)
Maturidade / Padronização do Protocolo De Facto Standard (established open-source reference for capability-based decentralized storage; 15+ year history; no formal standards body)
Política de Atualização Immutable (for immutable files) / Mutable (versioned) for mutable directories and files (MDMF format)
Mecanismo de Prova de Armazenamento Merkle audit proof (continuous integrity checks; storage servers audited by requesting random shares; failed audits trigger data repair)
Modelo Econômico / de Incentivo Volunteer (no economic incentive model; operators run nodes for altruistic or cooperative reasons; lease-based GC to manage storage)
Garantia de Recuperação Best-effort (configurable K-of-N erasure coding; 3-of-10 default tolerates 7 node failures; availability depends on operator commitments)
