Bro, here’s the real deal nobody explains: storing big data in Web3 is still a mess. Traditional blockchains are great for tokens and small state changes, but try dropping a video, ML dataset, or NFT media on-chain and your wallet cries.
@Walrus 🦭/acc actually solves this without compromise — it doesn’t dump everything on Sui, but it also doesn’t leave you stuck with centralized storage somewhere else.
Walrus is a decentralized blob storage and data availability protocol built to handle huge files across a network of independent storage nodes.
Instead of full replication, Walrus uses advanced erasure coding — think efficient spreading of data slices called slivers — so the cost stays low (~5× the blob size) and recovery is robust even if nodes go offline.
What’s cool is how it ties into the Sui blockchain: storage metadata, blob certification, availability proofs, payments, and node committees are all recorded on Sui.
The actual bytes sit off-chain with storage nodes, but everything else can be verified by smart contracts.
So your app can do things like check blob availability, extend storage time, or even delete data programmatically — all via on-chain logic.
This structure fixes major pain points:
High costs of full replication
Centralization risk from relying on pinned services
Developer friction when tying data logic back to contracts
It’s not flashy, but Walrus turns storage into a programmable Web3 resource — and that’s the missing piece if you care about real long-lived dApps.
