What is a walrus? Decoding the "marine mammal" of Web3 storage with $140 million in funding

When mentioning Walrus, many people might ask: “What kind of creature is Walrus?” This question isn’t just about the biological animal but also relates to one of the most anticipated decentralized storage protocols on the Sui blockchain. Developed by Mysten Labs (the company behind Sui), Walrus officially launched on March 27, 2025, with a funding scale of up to $140 million. From the moment of announcement, the protocol attracted widespread attention from the crypto community. But what’s truly interesting is that behind the name “Walrus” lies a profound design philosophy.

Why the name “Walrus”? From the sea to blockchain

“Walrus” means “海象” in Chinese — a large, resilient animal capable of adapting strongly to harsh environments. The developers of Walrus deliberately chose this name. The official slogan, “Reliable as a walrus, adaptable as a walrus,” reflects the core values of the protocol: providing storage solutions that are both trustworthy and flexible for the entire Web3 ecosystem.

Just like the walrus can survive in extreme conditions, easily adapt, and never give up, Walrus is designed to handle the complex challenges of decentralized storage: data protection, ensuring availability, and maintaining low costs even as scale grows. This isn’t a random name choice but a thoughtful reflection of the protocol’s nature.

Walrus in the Sui ecosystem: A new star or genuine expectation?

Walrus isn’t a “child of Sui” in the default sense — it’s an independent protocol with its own governance token, WAL. However, its connection to Sui is very close. Sui provides the “control layer” for Walrus, managing the lifecycle of storage nodes, data management, and economic incentives. Meanwhile, Walrus focuses on its core tasks: secure storage, quick retrieval, and efficient data management.

Since its launch, Walrus has made a strong impression. During the testing phase, the protocol attracted 14 million accounts, processed 5 million blobs (large binary files), with a total usage of 27.85 TB, and an average blob size of 5.57 MB. These figures demonstrate that Walrus isn’t just a theoretical idea but a real system capable of handling load in practical use cases.

However, the road ahead isn’t smooth. On March 27, 2025, when WAL was officially listed on major exchanges like Upbit, Bybit, and Kraken, its token price surged to $0.87 briefly before dropping to $0.39. As of March 2026, WAL’s price has adjusted down to $0.08, with a fully diluted valuation (FDV) of $398.5 million. Despite the price decline, this reflects a normal market correction after launch, not failure.

Technical secret: RedStuff — the decentralized storage revolution

If you think of Walrus as a “walrus,” then “RedStuff” — its proprietary encryption method — is its technical backbone. To understand RedStuff, imagine you have a large photo (say, a 1GB video) and want to store it across many friends’ computers but without each person holding a full copy.

RedStuff solves this through a method called “2D slicing.” It divides data into “primary chunks” and “recovery chunks” — similar to dividing a spreadsheet into rows and columns. Primary chunks handle storage and reading, while recovery chunks handle backup and restoration. When a node goes offline, the system only needs to gather a small part of slices from other nodes, rather than re-downloading the entire file.

What’s even smarter is that it uses XOR operations (equivalent to logical addition/subtraction) instead of complex polynomial calculations. This approach is much faster, allowing Walrus to handle larger files, support more storage nodes, and truly achieve decentralization. The data replication factor in Walrus is only 4 to 5 times, significantly lower than traditional solutions that often require 25 times.

Additionally, Walrus employs an “aggregate verification” mechanism instead of verifying each file individually. It confirms data existence by checking all storage nodes collectively, reducing verification costs from “linear growth” (cost increases with more files) to “logarithmic growth” (file volume has little impact on verification cost).

Real-world comparison: Walrus versus competitors

To understand why Walrus matters, we need to look at the shortcomings of current decentralized storage protocols. Filecoin ($FIL), with a circulating market cap of $778.3 million, focuses on static storage but can’t support real-time updates or dynamic interactions. Arweave ($AR), with a market cap of $108.52 million, aims for permanent storage but data cannot be modified. Celestia ($TIA), with a market cap of $301.12 million, concentrates on data availability layers but isn’t a complete storage solution.

Walrus aims to fill these gaps. It not only securely stores data but also makes data “live” — through integration with smart contracts, data can be called dynamically, updated in real-time, and support version control. Most importantly, its storage costs are only one-fifth of traditional cloud storage, while still ensuring high availability.

Thanks to Sui’s high processing speed and the efficient RedStuff architecture, Walrus offers a unique combination: decentralized storage at low cost, fast retrieval, and full programmability. This is a formula that older protocols haven’t achieved.

WAL token: More than just currency

The WAL token is distributed with a balanced model. Over 60% is allocated to the community: 10% for initial airdrops, 43% for community reserves (funding developers, incentive programs), 10% for storage subsidies (supporting storage nodes). Additionally, 30% goes to core contributors, and 7% to investors.

WAL isn’t just a fee payment tool. It also incentivizes storage nodes — nodes earn WAL rewards by storing data and responding to read requests. Moreover, WAL is a governance token, allowing holders to participate in protocol parameter adjustments, such as pricing models or reward mechanisms.

Future outlook: Can “the walrus” dominate the Web3 sky?

Walrus combines high-level technical design, support from a high-performance blockchain (Sui), and an active community ecosystem. Its RedStuff solution addresses core decentralized storage issues that previous protocols couldn’t overcome.

However, the path to success isn’t straight. Filecoin and Arweave still hold strong reputations in this space. Walrus needs to continue deploying technology, expanding decentralized applications on its platform, building a robust community, and finding meaningful real-world use cases.

2025 saw Walrus’s impressive debut. 2026 will be the year it proves that, like a walrus in nature, it can not only adapt but also truly dominate in the Web3 storage arena.
