Walrus (WAL) is a decentralized storage and data availability protocol built on the Sui blockchain, designed to securely store and retrieve large binary files (“blobs”) with cost‑efficient erasure coding and high availability. Developed by Mysten Labs, the team behind Sui, Walrus offers unique features such as:

Advanced erasure coding for storage costs of roughly 5× the original blob size (vs. 3×–10× for full‑replication)

Native Sui smart‑contract integration, representing storage space and blobs as on‑chain objects for programmable management

Delegated proof‑of‑stake governance, where WAL holders stake to elect storage‑node committees each epoch

By engaging with Walrus, users can stake WAL tokens to secure the network and earn rewards, pay for reliable, low‑cost storage of large files, and integrate on‑chain storage capabilities into decentralized applications, making it a standout project in the decentralized storage sector.
