Walrus solves a major problem in decentralized storage called asynchronous challenges. In many networks, dishonest nodes can trick the system.
They might pretend to store your data but actually delete it to save space. They only grab the data from other nodes when they are being tested. This is a huge security risk.
Walrus uses a clever two dimensional encoding system to stop this. It sets different rules for storing and checking data. Because the network does not rely on perfect timing, an attacker cannot quickly gather enough information to pass a storage check if they have already deleted the file.
This ensures your files are truly safe even if the internet is slow or a node is acting sneaky. By making these challenges work in an asynchronous setting, Walrus provides a higher level of trust than older systems.
It makes sure that every node is actually doing its job at all times.
