In the highly competitive decentralized storage sector, Walrus is not a follower but a true challenger holding core technology. Its killer feature is a 2D erasure coding algorithm called "Red Stuff"—which redefines how data is stored.

Traditional methods are painfully inefficient: copying files multiple times and dispersing them across nodes, with prohibitively high costs. Walrus took a different approach, slicing data into tiny "shards" and distributing them across the network using an optimized redundancy mechanism. With this change, efficiency skyrockets.

Numbers speak the loudest. Compared to schemes that require 25x redundancy to ensure data durability, Red Stuff only needs 4-5x redundancy to get the job done, and it can be made even more stable. Calculations show that storage costs can be reduced by over 80%. This not only saves money for users but also significantly improves overall network resource utilization.

The most impressive part is the recovery mechanism. Once data is encoded and dispersed, restoring it doesn't require retrieving all fragments—recovering a single shard is extremely low-cost. As a result, network resilience is outstanding—even if two-thirds of storage nodes go offline simultaneously, the original data can still be fully reconstructed. For projects requiring high availability and censorship-resistant storage, this is a real guarantee.

Walrus’s overall architecture is also thoughtfully designed. Data exists within a decentralized node network, with only hashes and storage proofs recorded on-chain (Sui) for key verification. This ensures data immutability and verifiability while avoiding astronomical costs associated with storing massive amounts of data directly on the blockchain. Security and efficiency are both achieved without compromise.

Walrus demonstrates through practical technological innovation that decentralized storage can be not only safer and more censorship-resistant but also cheaper. This is the true evolution that the storage sector needs.
