Walrus is about making large data usable in decentralized apps. Most blockchains can’t store files like videos or datasets, so Walrus fills that gap on Sui. Instead of copying a file everywhere, it splits the data into coded pieces and spreads them across many storage nodes. I’m paying WAL to keep that data available for a fixed time, and they’re earning rewards for maintaining it correctly.
What makes this useful is reliability. Even if some nodes fail or go offline, the original file can still be rebuilt. Apps don’t need to trust a single provider, and developers don’t need custom infrastructure. Walrus also connects cleanly to on-chain logic, so contracts can reference stored data without holding it themselves. The goal isn’t flashiness—it’s dependable storage that works with smart contracts and scales as apps grow.
