Walrus is a programmable storage network built on the Sui blockchain (what is Sui?). It lets developers store, deliver, and manage large data files (blobs) on-chain, making data programmable and tamper‐resistant.
Originally developed by Mysten Labs (the Sui team), Walrus is now championed by the Walrus Foundation. it secured $140M in funding (led by Standard Crypto, a16z crypto, Franklin Templeton, etc.).
Walrus uses a novel 2D erasure-coding scheme (“RedStuff”) to split and store data shards across many nodes with only 4–5× replication.
Walrus provides first-class tools (a CLI, JSON/HTTP APIs, and SDKs) and integrates with Move smart contracts on Sui, so apps can programmatically store and update data. It supports traditional web protocols (caching, CDNs) for smooth integration.
$WAL $WAL token for storage payments, staking, and governance. Mainnet launched in March 2025, and tokenomics plans include community airdrops and subsidies.
In other words, Walrus lets developers publish and manage rich data on-chain with the ease of a storage API, while leveraging blockchain security.
Walrus’s design, features, and how to try it out. We cover its tech innovations (like erasure coding), its backing and funding,tokenomics and future roadmap
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.
