Walrus is an innovative decentralized storage network designed for blockchain applications and autonomous agents. Released as a developer preview for Sui builders, Walrus combines efficiency, robustness, and decentralization—with plans for broader adoption across web3 communities.
Key Innovations in Walrus
Leveraging advanced erasure coding, Walrus encodes unstructured data blobs into smaller slivers distributed across a decentralized network. Key features include:
- Minimal Replication (4x–5x): Comparable to cloud services but with decentralized resilience.
- High Fault Tolerance: Original data can be reconstructed even if 66% of slivers are lost.
- Cost Efficiency: Storage nodes use minimal resources per blob, scaling economically.
The Replication Challenge in Blockchain
While Sui’s blockchain introduces a storage fund to manage on-chain data costs, it still requires 100x replication among validators—making it inefficient for unstructured data (e.g., media, historical records). Walrus addresses this gap.
Why Walrus Stands Out
1. Cost-Effective Decentralized Storage
- Upload gigabytes of data at minimal cost.
- Horizontal scalability via the Sui Network supports exabyte-level storage.
2. Unmatched Data Availability
- Certify availability without full downloads.
- Resilient to adversarial attacks or node failures.

Use Cases for Developers
Walrus empowers web3 builders with versatile applications:
- NFT Media Storage: Host images, videos, and game assets directly.
- AI & Data Provenance: Securely store training datasets or model weights.
- Blockchain Archives: Low-cost, long-term history storage for Sui checkpoints.
- L2 Support: Certify data availability for rollups and validity proofs.
FAQs
Q: How does Walrus achieve low replication costs?
A: Through erasure coding—splitting data into slivers with redundancy, requiring only 4x–5x replication.
Q: Can Walrus replace centralized storage for enterprises?
A: Yes! It offers disaster recovery with decentralized integrity and transparency.
Q: How do developers interact with Walrus?
A: Via CLI, JSON/HTTP APIs, and SUI Testnet tokens for Devnet access.
Future Roadmap
- Dynamic node management and expanded tooling based on community feedback.
- Integration with more web3 ecosystems.
