Programmability: Storage is a Move-native resource. Blobs have on-chain IDs and attributes, letting smart contracts read or delete them. Developers can build logic around the data lifecycle (e.g., auto-expiring files).
Composability: Because Walrus data lives on Sui, it composes with the rest of the Sui ecosystem. Apps can mix and match on-chain code and off-chain storage seamlessly.
Performance & Resilience: Using RedStuff 2D erasure coding, even if many shards are offline, files can be reassembled quickly with minimal replication overhead.
Web3 Focus: Walrus assumes a “permissionless” approach: anyone can run a storage node by staking WAL, and any user can programmatically manage storage via web3 tools. In that sense, it is like a data availability chain specialized for big data.
