#walrus $WAL
Walrus organizes decentralized blob storage in epochs, using an active committee of storage nodes to hold and serve data during each period. Committee membership can change at epoch boundaries based on delegated stake, so control over storage isn’t meant to be permanently concentrated in the same hands. When you upload to Walrus, your blob is encoded into redundant “slivers” using erasure coding (Red Stuff) and distributed across the committee, so the system can still recover data even if some nodes fail or act maliciously. Availability is enforced through quorum-based certificates: stores collect a supermajority of acknowledgements, and a Proof of Availability is posted on Sui so the network has a verifiable record that the blob was accepted for storage. This design is less about marketplace bidding and more about predictable, protocol-defined guarantees and incentives—nodes are selected and rewarded through stake and fees rather than winning individual storage deals. Walrus has been positioned as especially useful for Sui ecosystem apps that need reliable hosting for on-chain-linked assets like NFT media and other blob-backed data without falling back to Web2 storage.
