@Walrus 🦭/acc is a decentralized storage and data availability protocol for large files, and it is designed around one practical idea:
blockchain apps often need real content, but putting that content directly onchain is too expensive and too heavy. Walrus solves this by keeping blob data in a dedicated storage network while using Sui as the coordination layer that records commitments, certificates, and lifecycle events. I’m focusing on this structure because it turns storage from an informal backend detail into something applications can verify and reference onchain.
When a user stores a blob, the client encodes it into many smaller pieces and distributes those pieces across an active committee of storage nodes. This spreading is done so the original file can be reconstructed even if a meaningful portion of nodes go offline or behave incorrectly. After a quorum of nodes signs that they have stored their assigned pieces, the client publishes a proof on Sui that marks the point of availability. From that point onward, the network is accountable for keeping the blob available for the storage duration that was paid for.
Walrus also uses staking and incentives to align operators with uptime and correct custody. They’re trying to make reliability something the protocol can enforce rather than something users simply hope for. The long term goal is a storage layer that supports real applications, rich media, and AI datasets with predictable availability and clear accountability.
