Mobile storage is once again running low, with hundreds of photos piling up and cloud service providers frequently urging for payments. This passive feeling is really uncomfortable. When storage is in someone else's hands, data security is always a concern.

Recently, I discovered an interesting project in the Sui ecosystem—Walrus Protocol. Simply put, it is a decentralized data storage network. Photos, files, and various data are no longer stored on a single company's servers but are encrypted, fragmented, and distributed across nodes worldwide. The keys are in your own hands, so no one can freely manipulate your information.

They recently initiated a discussion in the community: "Your data is alive, but is it truly under your control?" This question struck many people. Indeed, why are our digital assets controlled by centralized platforms?

Speaking of credibility, there's a real case worth mentioning. A frontend project called Tusky was shut down, but user data stored via Walrus (such as Pudgy Penguins) was not lost, and the migration was smooth. This is the true meaning of "permanent preservation."

Its application scenarios are also expanding. Many AI projects and game studios now use it to store models and high-definition assets because it is fast and cost-effective—reportedly only one-third to one-fifth of the cost of centralized storage solutions. For developers who value efficiency, this cost-performance ratio is hard to refuse.

Thinking deeper, this represents a major trend. Your digital memories, creative content, and identity data should inherently be in your own hands. Protocols like Walrus make "data sovereignty" no longer just talk but a tangible reality. More and more people will realize that it's time to move their digital lives to a safer place.
