@Walrus 🦭/acc is a decentralized storage and data availability protocol focused on blobs, meaning large files that are too heavy to keep fully onchain. Instead of copying a whole file everywhere, Walrus encodes it with erasure coding into many smaller fragments and assigns those fragments to storage nodes. The design matters because recovery is where many storage networks quietly break, so Walrus uses a two dimensional coding approach, called Red Stuff, to make repairs more bandwidth efficient when nodes churn or go offline.
Sui acts as the control plane: users acquire storage for a time window, register the blob, upload fragments to the active committee, and then publish an onchain proof of availability once enough nodes acknowledge storage. After that moment, the network is responsible for keeping the blob retrievable through the paid period, and readers can reconstruct the file and verify it against the blob id, which helps expose corruption instead of hiding it.
WAL is used for paying for storage and for delegated staking that helps select and incentivize storage nodes, so performance and reliability can be rewarded over time. I’m interested in Walrus because it treats storage as a verifiable service rather than an informal hosting arrangement. They’re trying to make long lived data feel safer for apps that depend on media, archives, or datasets, while keeping costs practical.
Long term, the goal looks like programmable data custody where applications can reference blobs with clear availability guarantees and renewals can be automated, so data stays present even after teams, servers, and assumptions change, without asking anyone to trust.
