The first time I came into contact with Walrus was because it did something different in the storage track.

As someone who has been observing Web3 infrastructure for a long time, I have seen many storage projects, but most are either simple migrations of existing technology or more conceptual than practical. Walrus is different—it uses the Red Stuff 2D erasure coding scheme, directly changing the way decentralized storage works.

There are basically two traditional approaches. The first relies on multiple copies: storing multiple copies of data across different nodes, which guarantees security but is extremely costly. The second uses erasure coding, which reduces costs but makes data recovery a headache—full of trouble. Walrus’s solution, on the other hand, can achieve a high level of security with just 4.5 times replication factor. The key is that nodes can join or leave at will, and the system can automatically repair data. During data recovery, bandwidth consumption is proportional to the amount of data lost—that’s truly a technical hard currency.

What’s even more impressive is its seamless integration with the Sui ecosystem. As the core part of the Sui Stack, data is directly stored as "Storage Object" and can be called and interacted with via Move smart contracts. Developers don’t need to switch back and forth between storage layers and on-chain logic. This level of integration effectively solves the problem of disconnection between traditional storage and blockchain.

After several months of in-depth testing and research on this project, Walrus’s innovations in technical architecture are even more than these—
