If we compare the underlying public chains of the Web3 world to the human cerebral cortex, responsible for logic and settlement, then the storage protocol is the 'hippocampus' and 'library' of this civilization. Looking back from the node of January 2026, the decentralized storage field has evolved from the early 'hard disk mining' barbaric growth stage to the current era of the Three Kingdoms: the established archive Filecoin, the eternal monument Arweave, and the newly emerged massive multimedia engine Walrus.
This war is no longer about who has more hard disks, but about who can bear the 'digital flesh and blood' of large-scale Web3 applications.
Part One: The 'Species Evolution' and Ecological Niche of the Three Giants
To understand the core differences among these three, we can use urban infrastructure as a vivid analogy.
Filecoin (**FIL**) is like a giant industrial warehouse located in the suburbs. Its logic is 'leasing'; you pay to rent a storage space, and it ensures your items are still there through proof of space and time (PoSt). Its advantage is its massive scale, having surpassed 25EiB of effective storage capacity by the end of 2025, making it the first choice for institutional-level backups. However, its pain points are also evident: slow data retrieval, like searching for files from ten years ago in a cold storage facility, making it unsuitable for frequent interactions.
Arweave (**AR**) is like a monument carved at the edge of the digital universe. It adopts a donation fund model of 'one-time payment, permanent storage'. You prepay for storage costs for the next two hundred years. This makes it a sanctuary for NFTs, historical contracts, and immutable code. It is the 'historical archive' of Web3, but its cost structure makes it difficult to bear the PB-level short video data generated daily on social media.
Walrus (**WALRUS**), as a new generation, is positioned more like a 'distributed high-speed SSD array'. It is not meant to store 'cold data that is stored but not used', but to support large-scale 'hot data'. It relies on the underlying logic of the Sui ecosystem and utilizes advanced erasure coding technology to shard and distribute files. Even if two-thirds of the nodes go offline, you can still recover video playback in seconds.
Part Two: Walrus's Technical Breakthrough - Why is it the protagonist in 2026?
Why did market funds start to tilt towards Walrus in large scale in the second half of 2025? The core lies in the 'marginal breakthrough in storage cost and efficiency'.
Traditional decentralized storage often faces the 'redundancy paradox': to ensure safety, multiple backups are necessary, but this leads to doubled costs. Walrus achieves an extremely low redundancy ratio (usually only 1.1 to 1.5 times) through the ReduPans algorithm, yet can achieve higher reliability than Filecoin's replication model.
More critically, it is deeply integrated with **SUI**. As of today in 2026, Web3 social protocols and decentralized YouTube have become mainstream, and these applications need:
Low latency: Clicking on a video should not result in buffering.
2. Dynamism: Content needs to be updated frequently and retrieved quickly.
3. Composability: Storage is no longer an island but an object (Blob) that can be directly invoked by smart contracts.
While **FIL** is still struggling with its FVM virtual machine trying to make data move, **AR** is still insisting on its woven network, Walrus has already pushed Web3 applications into the era of instant loading through 'native object storage'.
Part Three: The Game of Economic Models and Value Capture
From the perspective of investment and holding, the logic among the three is completely different:
**FIL**'s value comes from 'collateral demand'. Storage service providers need to stake a large number of tokens, which is a typical B-end driven logic. With the influx of enterprise-level data in 2025, the inflation pressure on **FIL** has eased, but its asset attributes lean more towards 'digital utility stocks'.
**AR**'s value comes from 'scarcity and certainty'. Its donation fund pool will grow significantly in 2025 with the surge of permanent data, and the **AR** token resembles 'digital gold', representing ownership rights to future eternal space.
The token economics of WALRUS is more explosive. It introduces storage resource nodes and proof of stake. Because Walrus handles high-frequency traffic data, its tokens are not only governance certificates but also carriers of 'bandwidth and throughput capacity'. With the explosion of GameFi and SocialFi within the Sui ecosystem, the demand for **WALRUS** is real-time, high-frequency, and rigid.
Part Four: Risks, Challenges, and Future Intersection Points
Although Walrus has shown strong latecomer advantages, it is not without challenges.
First is the test of decentralization. As a protocol pursuing speed, how to maintain high performance of nodes while avoiding the path to high centralization like some L1s? This is the primary issue the Walrus team will face in 2026.
Next is compliance. As massive multimedia content floods into Walrus, how to handle content review and copyright protection in a decentralized environment will be key to its transition from a geek toy to a mainstream platform.
The trend in 2026 is very clear: storage is no longer an independent track, but a competition of 'computation + storage + bandwidth' in a trinity. Filecoin is striving to fill its shortcomings through the computation layer, Arweave is trying concurrent computing through the AO project, while Walrus is leading the way through seamless integration with high-performance L1.
Reader action suggestions:
Asset allocation perspective: If you value long-termism and anti-censorship, **AR** remains the ballast; if you focus on the traffic dividend brought by the explosion of Web3 applications, **WALRUS** is the current alpha.
2. Observation indicators: Pay attention to the geographical distribution diversity data of Walrus nodes, and whether the top ten DAU applications in the Sui ecosystem have fully migrated to Walrus storage.
3. Risk warning: Be vigilant about the impact of AI model training data compliance policies on the overall storage track, which may lead to short-term fluctuations.
In this battle of the 'three storage giants', the ultimate winner may not be the one who started first, but the one who makes users unaware that 'I am using blockchain storage'. Walrus is following this path, fleshing out Web3.
