Walrus is a decentralized storage and availability protocol optimized for large binary files (blobs) with Byzantine fault tolerance.

Walrus is a decentralized blob storage system developed by MystenLabs, designed to store large unstructured binary files across decentralized storage nodes. It emphasizes high availability and reliability, even in the presence of Byzantine faults, which are failures caused by nodes acting maliciously or unpredictably. This makes Walrus suitable for applications requiring robust and fault-tolerant storage of large data objects in a decentralized environment.
The protocol focuses on ensuring data availability and integrity by distributing blobs across multiple nodes, enabling redundancy and fault tolerance. Walrus is particularly useful for developers and enterprises building decentralized applications (dapps) that need to store large files such as media assets, datasets, or other binary content without relying on centralized servers. It integrates with decentralized networks and can be accessed via its open-source codebase and documentation.
Walrus differentiates itself by targeting large binary files specifically, rather than general-purpose decentralized storage, and by providing Byzantine fault tolerance to maintain data availability despite adversarial conditions. The project is open source under the Apache 2.0 license, with comprehensive documentation available as a Walrus Site and on GitHub Pages. Developers can build and serve the documentation locally using Rust tooling, facilitating easy onboarding and contribution. Community support is available through GitHub discussions and issue tracking.
Storing large unstructured binary files reliably in a decentralized network is challenging due to node failures, malicious actors, and data availability issues. Existing decentralized storage solutions may not guarantee high availability or Byzantine fault tolerance for large blobs.
Distributes data across multiple nodes to ensure redundancy and fault tolerance.
Protocol design ensures data remains accessible even under adverse network conditions.
Supports multiple languages and community translations to broaden accessibility.
Developers can use Walrus to store large video or image files for decentralized social media or content platforms.
DeFi projects can leverage Walrus to ensure critical off-chain data blobs remain reliably accessible.
Enterprises can implement Walrus for secure, fault-tolerant backup of large binary datasets without centralized dependencies.
