Arweave

Rede de Armazenamento Descentralizada

Permanent, pay-once decentralized storage network built on a blockweave data structure, where miners are incentivized through Succinct Proofs of Random Access (SPoRA) to store rare data perpetually. Hosts the 'permaweb' — an immutable, censorship-resistant web of permanently stored applications and data.

Rede de Armazenamento Descentralizada Atributos

Origens Permanent data archival / decentralized web hosting
Banco de Dados Blockweave (DAG variant with dual-block linking)
Linguagem de Consulta GraphQL (via gateway layer); REST API
Formatos de Dados JSON + arbitrary binary (any file type); ANS-104 bundled transactions
Suporte Móvel N/A (protocol/storage layer)
Suporte Web Yes (permaweb accessible via HTTP gateways in any browser)
Aplicativos Nativos N/A (protocol layer; apps built on top)
Termos Self-hosting (run a node); pay-per-transaction (one-time fee)
Fundos $14.4M total (ICO 2018 ~$8.7M; $5M a16z/USV/Multicoin 2019; $8.3M a16z/Coinbase Ventures 2020)
Baseado Em Novel (original blockweave; not built on existing protocol)
Arquitetura P2P Public blockchain (blockweave with SPoRA consensus)
Rede de Sobreposição Global
Endereçamento por Conteúdo Yes (transaction IDs are SHA-256 content hashes)
Local-First N/A (miners replicate; clients are ephemeral)
Criptografia de Ponta a Ponta (E2EE) No (data is publicly readable by default; encryption is opt-in at app layer)
Tolerância a Falhas Bizantinas Yes (SPoRA consensus; democratic content policy for node-level moderation)
Assinatura RSA-4096 (wallet signatures); SHA-256 content hashing
Permissões N/A (fully public by default; access control at application layer)
Compatibilidade com a Web Semântica N/A
Contrato Inteligente Yes (via SmartWeave / Warp contracts on-chain)
Posição na Pilha de Protocolo Application-layer (built on TCP/IP)
Incorporação de Ativo / Valor Native (AR token embedded at transaction/block level; storage fees paid in AR)
Maturidade / Padronização do Protocolo De Facto Standard (stable, widely adopted permaweb; no formal standards body)
Política de Atualização Immutable / Append-only (data written to blockweave cannot be deleted or modified; IPNS-like mutable pointers available via SmartWeave)
Mecanismo de Prova de Armazenamento Proof of Access (PoA) / Succinct Proofs of Random Access (SPoRA) — miners must prove access to a randomly selected historical block to mine new blocks, incentivizing wide data replication
Modelo Econômico / de Incentivo One-time endowment (permanent storage model): upfront AR token fee funds a storage endowment; interest from endowment pays miners indefinitely as storage costs decline
Garantia de Recuperação Best-effort (incentivized but not formally guaranteed; data persistence depends on endowment viability and miner participation)
