When it comes to decentralized storage, most people's first reaction is that it's expensive. But Walrus Protocol offers an alternative solution.

This is a storage protocol specifically designed for the Sui blockchain, with a fundamentally different underlying logic. It uses a set of two-dimensional encoding algorithms called Red Stuff, which is the core innovation. Compared to traditional solutions that often require 500 times data redundancy, Walrus only needs 4 to 5 times, directly reducing storage costs by 80%. In other words, with the same budget, you can store more data, or spend less to store the same amount of data.

On the technical level, the protocol employs erasure coding, splitting files into fixed-size blocks, each of which is further encoded with erasure codes to generate multiple fragments stored across different locations. Even if two-thirds of the nodes fail, the remaining fragments can still fully recover the original data. This redundancy design ensures high data availability without worries about data loss.

More importantly, the deep integration with Sui. Smart contracts can directly interact with stored data, meaning storage is no longer just passive storage but becomes programmable storage. DApp developers can build applications that were previously unimaginable based on this capability, greatly expanding the possibilities of decentralized storage.

From technical efficiency to economic models and application ecosystems, Walrus simultaneously breaks through multiple bottlenecks in decentralized storage.
