Walrus is a simple way to store big files—like photos, videos, or AI data—safely across many computers on the internet, without relying on one company.
It is built by the team behind the Sui blockchain. You use it almost like a regular online storage service, but the data is spread out so it stays safe even if some computers stop working.
How it feels to use
Pick your file.
Upload it with a small tool on your computer or through simple code.
Pay a small fee with WAL tokens.
Later, get the file back easily—often just by clicking a normal web link.
It works smoothly in browsers or apps, no special wallet needed for viewing.
Why it stays simple
Walrus breaks your file into small pieces and adds extra information using a smart method called RedStuff. This is like a puzzle: you only need a few pieces to rebuild the whole file, even if many are missing or broken. It uses about 4 to 5 times the original space in total—not a lot more like some other systems. This keeps things cheap and very reliable.
Groups of computers hold these pieces. They change regularly to keep everything fair. The Sui blockchain quietly tracks ownership, storage time, and proof that your file is safe.
What you actually get
Lower cost — especially good for large files, often cheaper than big cloud services.
Strong safety — your file stays available, and you can check it is really there.
Easy control — you can renew storage, update files, or share access using simple programs on Sui.
Useful for many things — saving important photos, building apps with videos, storing data for AI, or even hosting websites that no one can easily take down.
Tools are beginner-friendly: a command tool for basic use, code helpers for apps, and web links for quick access.
As of today 15th January 2026, Walrus has been live on its full network since 2025. It keeps getting better with faster uploads, better handling of small files, and ways to use it from other blockchains too.
In short, Walrus puts the helpful parts first: easy, affordable, and safe storage. The clever technical work—like special puzzle pieces and network management—stays in the background so you can just focus on your files.
