Arweave

Decentralized Storage Network

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.

Decentralized Storage Network Atributos

Origins Permanent data archival / decentralized web hosting
Database Blockweave (DAG variant with dual-block linking)
Query Language GraphQL (via gateway layer); REST API
Data Formats JSON + arbitrary binary (any file type); ANS-104 bundled transactions
Mobile Support N/A (protocol/storage layer)
Web Support Yes (permaweb accessible via HTTP gateways in any browser)
Native Apps N/A (protocol layer; apps built on top)
Terms Self-hosting (run a node); pay-per-transaction (one-time fee)
Funds $14.4M total (ICO 2018 ~$8.7M; $5M a16z/USV/Multicoin 2019; $8.3M a16z/Coinbase Ventures 2020)
Based On Novel (original blockweave; not built on existing protocol)
P2P Architecture Public blockchain (blockweave with SPoRA consensus)
Overlay Network Global
Content Addressing Yes (transaction IDs are SHA-256 content hashes)
Local-First N/A (miners replicate; clients are ephemeral)
E2EE No (data is publicly readable by default; encryption is opt-in at app layer)
Byzantine Fault Tolerance Yes (SPoRA consensus; democratic content policy for node-level moderation)
Signature RSA-4096 (wallet signatures); SHA-256 content hashing
Permissions N/A (fully public by default; access control at application layer)
Semantic Web Compatibility N/A
Smart Contract Yes (via SmartWeave / Warp contracts on-chain)
Protocol Stack Position Application-layer (built on TCP/IP)
Asset / Value Embedding Native (AR token embedded at transaction/block level; storage fees paid in AR)
Protocol Maturity / Standardization De Facto Standard (stable, widely adopted permaweb; no formal standards body)
Update Policy Immutable / Append-only (data written to blockweave cannot be deleted or modified; IPNS-like mutable pointers available via SmartWeave)
Storage Proof Mechanism 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
Economic / Incentive Model One-time endowment (permanent storage model): upfront AR token fee funds a storage endowment; interest from endowment pays miners indefinitely as storage costs decline
Retrieval Guarantee Best-effort (incentivized but not formally guaranteed; data persistence depends on endowment viability and miner participation)
