A major weakness of traditional decentralized storage systems has always been trust. Users love the idea of removing centralized control, but they hesitate because one question remains unanswered:
Can I rely on my data to survive long term?
Walrus was created to solve that exact problem.
Instead of duplicating entire files across multiple machines, Walrus transforms every file into a set of encoded fragments. These fragments are then distributed across many independent storage providers in the network.
What makes this approach powerful is that the original file does not require every fragment to be available. As long as a sufficient subset of fragments can be retrieved, the full data can be reconstructed.
So if some nodes disconnect, shut down, or disappear entirely, your files remain safe.
This design dramatically increases fault tolerance while reducing storage costs — a combination that older decentralized storage models struggled to achieve.
