As a freelancer, storing business contracts and client information has always been a headache for me. The risk of data leakage is everywhere. It wasn't until I came across the privacy storage feature of a leading Web3 storage protocol that I found a real solution.

This system uses end-to-end encryption. The moment the file is uploaded, the system automatically generates a dedicated key. The key point is that only I can unlock and view the content; even the storage nodes can't access the data. This design is interesting — security is entirely in my hands.

How does it work in practice? I uploaded a cooperation agreement worth 200,000, and it took only 2 minutes from clicking upload to completion. In terms of cost, compared to traditional encrypted cloud storage, expenses were reduced by nearly 60%. This price difference is quite attractive for individual users and small businesses.

There's another detail worth mentioning. The system supports key sharding and custody. I split the key into 3 parts and stored each in different wallets. Even if one part is lost, I can recover the data through the other parts. This adds an extra layer of privacy protection.

The business collaboration scenario is also very thoughtful. When sharing files with clients, I don't need to transfer the key back and forth; I just generate temporary access permissions. Once the client views the file, the permission automatically expires, eliminating the risk of data leakage.

Currently, many small and micro enterprises are using this feature to store financial reports and legal documents. Its application scope is broader than I initially thought. It’s clear that this type of Web3 infrastructure is truly addressing practical needs rather than just superficial gimmicks.

To be honest, a project focused on data privacy has much more stable long-term value. Compared to projects that rely on hype, privacy needs will always exist — that’s the real foundation of value.
