Walrus is a decentralized storage system built on Sui, focused on handling large files in a reliable way. Instead of saving full copies everywhere, it breaks data into coded pieces and spreads them across many nodes. If some nodes go offline, the file can still be rebuilt. I’m thinking of it as a storage layer apps can depend on, not a DeFi tool or payment network.
They’re using WAL as the coordination token. Apps pay WAL to store data for a period of time, and that value is distributed gradually to storage providers and people who stake with them. Everything runs in fixed time cycles, so availability can be checked and enforced. The purpose is simple: give developers and users a neutral place to keep important data without relying on traditional cloud services. I’m watching how builders start using it for real applications.
