Walrus is a decentralized data storage protocol designed to work with the Sui blockchain, and I’m looking at it as a long-term infrastructure project. The idea is simple: blockchains are good at transactions, but they struggle with large files. Walrus fills that gap.
They’re using blob-based storage combined with erasure coding to store data efficiently. Files are broken into encoded pieces and spread across the network, so they don’t depend on a single server or provider. This reduces the risk of data loss and makes censorship harder.
Developers can use Walrus to store application data, media, archives, or records that don’t fit directly on-chain. The WAL token is used for storage fees, staking, and protocol-level participation. I’m not seeing it as a consumer app, but as a tool developers build on.
Long term, they’re aiming to support decentralized apps, enterprises, and data-heavy Web3 systems. I’m interested because they’re focused on reliability and scalability, not marketing narratives.
