Speaking of the Sui ecosystem, Walrus always sparks interesting discussions. This newcomer in the storage track seems ordinary, but in fact, it has quite a different idea—aiming to fundamentally solve an old problem.

Application developers often face a dilemma: wanting data security and decentralization, but also not wanting to spend a lot of money or deal with complex deployment. Walrus is designed to address this contradiction, providing its own solution from a technical perspective.

The core technology is actually not complicated but very clever—breaking files into many small fragments, adding redundancy information, and dispersing them across various nodes. Even if some fragments are lost, the file can still be fully restored. This approach ensures security, keeps redundancy costs reasonable, and is the source of its cost advantage.

The accounting logic is also very smart. Large files are stored directly on nodes, with only metadata and verification proofs recorded on-chain—so the main chain won't be overwhelmed by data. The layered design of on-chain verification combined with off-chain storage is key to its ability to integrate into high-performance public chains like Sui.

From an ecosystem perspective, Walrus is closely integrated with Sui. As infrastructure, it works seamlessly with smart contracts, making it easy for developers to get started. This native integration capability is hard to replicate and greatly simplifies application development. It’s not just a storage tool but more like a usability layer that can support more application scenarios.

The ecosystem applications are also quite rich: from ensuring the permanence of NFT assets, balancing security and cost for DeFi protocols, to supporting more complex application needs. The connectivity of these scenarios demonstrates the practical potential of this solution.
