Walrus

Decentralized Storage Network

A decentralised blob store that uses the Sui blockchain for coordination and governance. Large files ('blobs') are encoded with the project's Red Stuff encoding and distributed across storage nodes, per the documentation; storage nodes and clients are Rust binaries, and Move contracts for Sui handle coordination and governance. A WAL token and its economics are set out in the project's whitepaper, and the design is described in a scientific paper. The project also offers Walrus Memory, a portable memory layer for AI agents, and Walrus Console for managing data .

Decentralized Storage Network Attributes

Owner - List
  • Mysten Labs
Origins A decentralised, efficient storage layer for large unstructured data, designed with a research paper and a whitepaper and built on Sui for coordination rather than operating its own chain
Database N/A
Query Language Blob store with documented APIs and SDKs; no query language is described
Data Formats Blobs with metadata and coordination state managed through Sui contracts; the cited sources do not describe the identifier scheme
Mobile Support Not described in the cited sources
Web Support Yes: the project provides a web console, documentation and a storage-cost calculator
Native Apps Rust binaries for storage nodes and clients (the repository's binaries)
Terms Open-source code under Apache-2.0; the project has a WAL token and a storage-cost calculator on its site
Funds Not stated by the project.
Based On Sui for coordination and governance; Red Stuff erasure coding, described in the paper 'Walrus: An Efficient Decentralized Storage Network'
P2P Architecture Storage nodes hold encoded pieces of each blob using the Red Stuff encoding, with Sui contracts handling coordination and governance; the cited sources do not describe committee and epoch mechanics
Overlay Network Yes: A storage-node network coordinated by contracts on Sui
Content Addressing Not confirmed in the cited sources: the documentation describes blob identifiers but the cited sources do not show how they are derived
Local-First No: a networked storage layer, not a local-first data layer
E2EE Not stated by the project.
Byzantine Fault Tolerance Designed for faulty or malicious storage nodes, per the paper's title and design goals; the cited sources do not give the exact threshold
Signature Not described in the cited sources
Permissions Coordination and governance are on Sui; the cited sources give no further detail
Semantic Web Compatibility N/A: no RDF, JSON-LD or SPARQL layer.
Smart Contract Yes: contracts for Sui handle coordination and governance, per the README
Protocol Stack Position Application-layer storage protocol with a blockchain (Sui) for coordination
Asset / Value Embedding WAL token for storage payments, staking and governance
Protocol Maturity / Standardization Production network (mainnet release train) with a published paper and whitepaper; no standards-body involvement
Update Policy Not described in the cited sources
Storage Proof Mechanism Not described in the cited sources; the repository's contracts handle coordination and governance
Economic / Incentive Model WAL token economics are covered by the whitepaper, according to the README; the cited sources give no details
Retrieval Guarantee Designed for efficient recovery with the Red Stuff encoding, per the paper; the cited sources do not state specific guarantees
