Centralized storage has always been a challenge—server outages, high costs, and privacy concerns. Walrus offers a different approach on the Sui blockchain, redefining file storage with a distributed architecture.

Talking about traditional cloud drives, many people have complaints. Monthly renewal fees, insufficient capacity alerts, occasional service interruptions... The worst part is when files are inaccessible at critical moments, or constantly worrying about data leaks. Ultimately, centralized storage is like putting all your eggs in one basket—risk is concentrated, and costs keep rising.

Walrus takes a different path. This protocol builds a decentralized, highly available, low-cost file storage network on Sui. It combines erasure coding and Blob storage technology to fundamentally change how data is stored.

How does it work? For example, suppose you upload a 1GB design file. The system first splits it into 10 original segments of 100MB each, then uses erasure coding to generate 5 additional backup segments. The benefit is obvious—even if some nodes fail, the remaining segments are enough to recover the complete file. Data no longer depends on a single service provider but is distributed across the entire network.

Compared to traditional centralized solutions, the distributed architecture achieves true redundancy and security. Files are less vulnerable to single points of failure, and there's no need to worry about data being censored or leaked in one place. In terms of cost, without middlemen and excessive infrastructure redundancy, prices are more transparent and lower.
