Decentralized storage is a rapidly expanding frontier in the blockchain space, currently representing a $9 billion market. Dominated largely by three major players—ICP, Filecoin, and Arweave—this sector underpins the foundational promise of true decentralization. After all, if your decentralized application (dApp) relies on centralized servers for data storage, how decentralized is it really? Not very—and certainly not enough for the future of Web3.
At the heart of crypto’s vision is the idea of user ownership, censorship resistance, and trustless infrastructure. Now, a new contender is emerging with the potential to redefine how we store and access data: Walrus. Built on the Sui blockchain by Mysten Labs, Walrus introduces a next-generation decentralized storage protocol designed for speed, efficiency, and seamless integration with modern Web3 development.
The State of Decentralized Storage Today
Currently, Filecoin and Arweave lead the decentralized storage landscape—but each comes with limitations. Filecoin, which leverages IPFS (InterPlanetary File System), dominates NFT metadata storage but faces criticism over node centralization. As noted by industry observers:
"Filecoin and IPFS still rely on centralized bootstrap nodes running on cloud servers. We have more steps to take to a better internet – but we are getting there."

Arweave excels in permanent file storage, particularly for hosting decentralized apps and websites. However, both platforms struggle with complexity, cost inefficiencies, and suboptimal developer experience when handling large-scale data.
Enter BLOBs—Binary Large Objects. These are unstructured chunks of data used to store media like images, videos, and other binary files. Most large files today are stored as BLOBs because they don’t require rigid schema or formatting. But traditional blockchains aren’t built to handle BLOBs efficiently.
That’s where Walrus changes the game.

Why Walrus Stands Out: Object-Based Storage Meets Move Language
Walrus isn’t just another decentralized storage solution—it’s an architectural evolution. Developed by Mysten Labs, the team behind Sui, Walrus leverages Sui’s unique object-centric model and the Move programming language to deliver a storage system that’s natively optimized for BLOBs.
Unlike Ethereum’s account-based model, Sui treats all data as objects. This means that when you store a BLOB in Walrus, it becomes a first-class citizen within the network—secure, addressable, and easily accessible.
Here’s why this matters:
- Native Object Support: Since BLOBs are inherently objects, storing them on an object-oriented blockchain like Sui enables faster reads, writes, and verifications.
- Lower Latency & Higher Throughput: Sui’s parallel execution engine allows multiple transactions to be processed simultaneously, drastically improving performance for data-heavy applications.
- Seamless Developer Experience: Integrating Walrus into dApps requires minimal boilerplate code. Developers can upload, retrieve, and manage data using simple APIs.
As one developer shared after testing Walrus:
"Wow, Walrus is so easy to work with! In just two hours, I deployed a Walrus aggregator and publisher across four global regions with geo-based routing on a private network."

This kind of rapid deployment showcases Walrus’s potential to become the go-to storage layer for global Web3 applications.
Who Can Use Walrus?
One of Walrus’s most compelling features is its cross-chain accessibility. While built on Sui, it's designed for any Web3 builder, regardless of their primary blockchain:
- ✅ Ethereum developers
- ✅ Solana builders
- ✅ Polkadot teams
- ✅ AI protocol engineers
Walrus provides open APIs and SDKs that allow seamless integration into any ecosystem. Whether you're building decentralized social media, AI-driven analytics platforms, or NFT marketplaces, Walrus offers scalable, low-cost storage without sacrificing decentralization.
Decentralized Storage Meets AI: Unlocking New Possibilities
Artificial intelligence is hungry for data—and decentralized networks like Walrus offer a new paradigm for AI training and inference.
Imagine a world where:
- AI models are trained on tamper-proof datasets stored across a distributed network.
- Data provenance is verifiable and transparent, eliminating bias or manipulation risks.
- AI agents operate autonomously, storing and retrieving information from Walrus without relying on AWS or Google Cloud.
Walrus can act as an infinite, permissionless dataset for large language models (LLMs) and other AI systems. Developers can query stored content via API to train models or build AI-powered search engines over decentralized content.
"#Walrus isn’t just storage – it’s creating a whole new trust layer for data where provenance and decentralization matter most."

By combining decentralized storage with AI, Walrus paves the way for truly autonomous, user-owned AI protocols—free from corporate control and surveillance.
Real-World Adoption: Akord Moves to Walrus
The industry is already taking notice. Akord, a secure decentralized storage and collaboration platform, recently announced its migration from Arweave to Walrus. The company cited superior performance, lower costs, and better developer tooling as key reasons for the switch.
Now rebranded as Tusky, the team is building its entire infrastructure on Walrus Testnet:
"Welcome @AkordApp to the herd! Akord is moving to Walrus Testnet soon—empowering users with meaningful data ownership and giving devs easy API access."
— Walrus Protocol
This early adoption signals strong confidence in Walrus’s long-term viability and scalability.
How to Get Started with Walrus (Testnet Phase)
Walrus is currently live on testnet, making now an ideal time to explore its capabilities before mainnet launch. You’re among the first developers and users shaping the future of decentralized storage.
Here’s how to begin:
- Set up a Sui testnet wallet (e.g., Sui Wallet browser extension).
- Get testnet SUI tokens from the Sui faucet.
- Visit the Walrus testnet faucet to receive testnet WAL tokens.
- Start uploading your own BLOBs (up to 10MB) at publish.walrus.site.
- Experiment with building a fully decentralized website hosted on Walrus.
No complex setup. No lengthy deployment cycles. Just intuitive tools that put powerful infrastructure in your hands.
