Web3 ecosystem is experiencing explosive growth, but a real challenge facing developers is that large file storage has become a bottleneck. Traditional cloud services seem cheap and convenient, but the cost is trusting a centralized entity not to choke the system, experience downtime, or forcibly delete your data. These risks are especially critical in finance and content sectors.

Against this backdrop, Walrus was born. It is a native decentralized storage network on the Sui blockchain, using an innovative technical framework to solve this longstanding problem. The protocol's native token $WAL not only drives network governance and staking mechanisms but also continuously incentivizes participants.

From a technical perspective, Walrus's cleverness lies in combining erasure coding with distributed blob storage. In simple terms, large files are split into N data fragments, which are redundantly dispersed across nodes worldwide. Even if some nodes go offline or are attacked, the remaining fragments can reconstruct the complete data through mathematical encoding algorithms. The benefits of this design are obvious: first, extremely high data availability; second, storage costs can be reduced to about one-tenth of centralized services.

More importantly, it offers censorship resistance. Data is not bound to any single entity, so even the greatest power cannot forcibly delete or tamper with it. This is especially significant for NFT metadata, decentralized media platforms, AI model repositories, or enterprise sensitive data backups.

Moreover, running on the Sui blockchain, Walrus naturally benefits from Sui's high throughput and parallel execution advantages, optimizing upload, retrieval, and verification efficiency. Users can also enable privacy mode when storing data, leveraging cutting-edge cryptographic tools like zero-knowledge proofs to protect information privacy. This combination not only addresses storage pain points but also grants data owners full control.
