My previous understanding of decentralized storage was quite superficial—I thought it was a patent exclusive to developers and large corporations, and that ordinary people’s photos and documents were enough stored on cloud drives. Although I occasionally worried about leaks or being limited, I never considered trying other solutions. It wasn’t until three months ago that I came across a certain distributed storage protocol, and with a mindset of giving it a try, I migrated all my five years of photos and important work documents from my phone. Looking back now, I realize how one-sided my understanding of this field was.

What truly attracted me wasn’t just the storage function itself, but the sharding storage technology it uses. I’m not a technical person and can’t understand obscure whitepapers, but simply put: your data isn’t stored intact on a single node, but is broken into countless small fragments, dispersed across various nodes in the network. Even if two-thirds of the nodes go offline simultaneously, the data can still be fully reconstructed. This fault tolerance is much safer than traditional centralized cloud storage. A friend of mine had their cloud account hacked, and all their graduation project and travel photos were lost, with no way for customer service to recover them. Since then, I’ve been worried that my core data might face the same risk. The mechanism of this protocol directly addresses that concern of mine.

When migrating the data, I was also worried it would be very complicated—after all, it’s several hundred gigabytes of content—but it turned out to be much smoother than I expected.
