Walrus as an ecosystem product of Mysten Labs is natively compatible with Sui's Move smart contract language. What does this native interoperability mean for developers? Simply put: it's awesome.

When writing contracts on Sui, you can directly and atomically control data permissions in the Walrus storage layer. It sounds abstract, but it becomes clear with a different scenario. Imagine an NFT trading platform where sellers upload high-resolution original images to Walrus, and the platform sets a contract: only buyers who have paid royalties can download the watermark-free large images from the node.

This logic may seem simple, but its power is immense—binding "asset ownership" and "data access rights" directly at the code level, something traditional cloud storage cannot do. You no longer need to maintain complex backend servers, database permission systems, or write a bunch of API authentication logic. On-chain contracts are the complete solution.

This kind of development experience will attract many Web2 engineers to explore Web3 out of curiosity. Not because of idealism, but because it truly saves effort—solving more complex problems with less code. This is the real value of composability.
