Walrus has sparked quite a bit of discussion in the Web3 storage space. Its selling point is very clear — turning off-chain data into native objects on the Sui public chain. Each uploaded content comes with a unique ID, clear ownership, an immutable hash, and can be programmed. Smart contracts can call it directly, the front end can verify in real-time, and users can transfer or destroy it. This indeed breaks the traditional "on-chain token + off-chain black box" separation.

The integration case with Flatlander looks promising — when users publish videos, they automatically become part of the Sui state, completely eliminating centralized servers. During playback, the front end pulls data shards from decentralized nodes, decodes them, and presents them, with full chain verification. It sounds quite exciting.

But looking deeper, the problems emerge. To ensure the integrity of on-chain state, users are actually caught in a new cage — the rigid framework of the Sui object model. Data is no longer locked by the platform but is locked by the specific data structures of the public chain. This highly proprietary representation method is difficult to migrate and almost impossible to interface with external systems. Some call this the "Object Model Trap."

Simply put: you save yourself, but are restricted by new rules. The lifecycle of objects, data composability, cross-chain portability — these issues are all in front of us, requiring real answers.
