Mobile device storage is never enough, which is a "common problem" for modern people. Photos, videos, and documents pile up, and every cleanup involves making tough choices. Traditional cloud storage memberships can solve space issues, but the risks of centralized data storage and privacy concerns have always existed.

Recently, I came across a decentralized storage protocol called Walrus Protocol, and its design concept is quite interesting. Rather than just an upgraded version of cloud storage, it completely "disperses" data—your data is sliced and stored across multiple nodes, similar to placing important items in different safes. A single node failure won't affect data integrity. Coupled with blockchain encryption protection, users have absolute control over their data.

It currently provides storage services for over 170 projects. For example, health applications like Cudis store users' sensitive health data on the protocol rather than centralized servers, allowing users to control who can view their data and for how long. An advertising data platform processes 25 million ad records daily, achieving data transparency and authenticity verification through this protocol.

What’s more attractive is the "programmable access" feature. Imagine sharing a creative work with a friend, and you can set permissions precisely—for example, the link expires after three days or can only be viewed but not forwarded. Some blockchain game projects are already using this feature to manage players' game saves.

Recently, the Sui network experienced an outage, but interestingly, data stored on Walrus was unaffected. This demonstrates the protocol’s independence and reliability—if the underlying public chain encounters issues, it won't impact data persistence.

Looking ahead, high-value data such as personal AI models, digital creation drafts, and NFT assets will require safer and more private storage solutions. Decentralized storage could truly change our understanding of data ownership and privacy.
