Walrus Is What - From Name to the Nature of the Web3 Storage Protocol

Walrus is best understood by its name—a marine mammal symbolizing resilience and adaptability. In reality, Walrus is an independent decentralized storage protocol built on the Sui blockchain ecosystem, officially launched on March 27, 2025, backed by $140 million in funding, with a fully diluted valuation (FDV) at that time of $2 billion. The name is no coincidence—the slogan “Reliable as a walrus, adaptable as a walrus” accurately reflects the project’s design philosophy: providing efficient, reliable, and flexible storage solutions for Web3 applications.

Walrus was created by Mysten Labs, the company behind Sui, with a development team mainly from Meta’s Diem project. This makes Walrus not just an ordinary startup but a product developed by experienced blockchain experts. Although it runs on Sui, the protocol remains fully independent, with its own governance token WAL, enabling it to serve not only the Sui ecosystem but also other blockchains.

What Is Walrus — Its Role in Decentralized Storage

When asking what Walrus is in the blockchain space, it’s important to understand its position among existing decentralized storage solutions. The field has pioneers like Filecoin (FIL) with static storage and Arweave (AR) with permanent storage models, but each has its limitations.

Filecoin has a market cap of about $736.94 million but focuses on static storage and does not support real-time data updates. Arweave, with a valuation of $125.72 million, aims for permanent storage but does not allow data editing. Celestia (TIA), valued at $336.14 million, concentrates on data availability (DA) layer but is just a data relay station rather than a complete storage solution.

Walrus aims to fill these gaps. The protocol not only securely stores data but also makes it “dynamic”—by integrating with smart contracts, data can be called dynamically, updated in real-time, and support version control. With WAL priced at around $0.08 (as of March 16, 2026), Walrus shows a price adjustment journey after its initial launch.

Why Walrus Is an Anticipated Solution in Web3 Storage

The main reason Walrus is significant lies in cost and performance. Its storage costs are only one-fifth of traditional cloud services like AWS and Google Cloud, while still ensuring high availability. In an era where AI data and NFT metadata are increasingly prevalent, this low-cost advantage is a major competitive edge.

Walrus’s practical applications are diverse. For NFTs, it provides decentralized storage for metadata, avoiding risks associated with centralized servers. In AI, it can store training data, ensuring integrity and supporting dynamic updates. For decentralized applications (DApps), Walrus can store source code and user interfaces, reducing single-point errors. Even for Rollups, Walrus offers a DA layer to lower on-chain storage costs.

Testnet network performance is impressive. Data shows it has attracted 14 million accounts, processed 5 million blobs (large binary data files), with a total active capacity of 27.85 TB. This demonstrates Walrus’s ability to handle large-scale data needs in practice.

RedStuff Technology — The Secret Behind Walrus’s Efficiency

From a technical perspective, Walrus’s standout feature is its RedStuff encryption. This is not an ordinary encryption solution but an advanced method designed specifically for large-scale decentralized storage.

RedStuff employs a unique “2D slicing” technique. Instead of dividing data into rows or columns, it slices into “main slices” (for storage and reading) and “auxiliary slices” (for backup and recovery). The advantage is that when a storage node goes offline, the system only needs to retrieve small data parts from other nodes to reconstruct the entire file, rather than re-downloading everything.

This results in a replication factor of 4-5 times, significantly lower than the 25 times typical of traditional cloud storage solutions. Additionally, instead of complex polynomial calculations, RedStuff mainly uses XOR operations—simple addition and subtraction—making it faster and enabling Walrus to handle larger files and more nodes.

Walrus’s proof-of-storage verification mechanism is also innovative. Instead of linear-time checks of individual files, it employs a “comprehensive verification” that tests all storage nodes simultaneously, with logarithmic speed growth. This greatly reduces verification costs.

Collaboration Between Walrus and Sui — Clear Division of Labor

Walrus’s architecture benefits from a clear division of labor with Sui. Sui acts as the “conductor”—managing storage nodes, assigning data storage responsibilities, distributing rewards, and coordinating tasks. Walrus focuses on “doing the work”—slicing, storing, and retrieving data.

This synergy creates an ideal foundation for future Layer 2 solutions. Sui’s high-performance computing combined with Walrus’s decentralized storage could potentially create a whole new L2 ecosystem.

WAL Token Economics — Incentives and Governance Structure

The WAL token is the heartbeat of the Walrus ecosystem, designed with a community-oriented distribution model. Over 60% of the total tokens are allocated to the community, including 10% for airdrops to users, 43% reserved for community funding, developer grants, and incentive programs, and 10% for storage subsidies supporting nodes. An additional 30% goes to core contributors, and 7% to investors.

WAL serves three main roles: first, as a payment tool for storage fees—users need WAL to pay for storing and accessing data. Second, as a reward for storage nodes—compensating them for storing data and responding to read requests. Third, as a governance token—allowing holders to participate in protocol parameter adjustments, such as pricing models or fee distribution mechanisms.

This economic model ensures Walrus’s sustainable long-term development and community empowerment.

Future Outlook — Can Walrus Become a Web3 Storage Leader?

From technological innovations to community-driven economic structures, Walrus is not just a storage protocol but a bold experiment in decentralized storage. It addresses previous protocol shortcomings through RedStuff, programmability, and high performance.

However, challenges remain. Filecoin and Arweave have long-standing user bases and ecosystems. Walrus must continue technological deployment, ecosystem expansion, community building, and demonstrate real-world value against competitors. Can Walrus become a leader in Web3 storage? The answer depends on its future development steps and its ability to adapt to market needs.
