Walrus as a storage layer solution for the Sui ecosystem means this tight technical coupling implies its stability depends not only on its own distributed node network, but is directly constrained by the operational status of the Sui mainnet.
We need to seriously consider a realistic extreme scenario: if the Sui network stops producing blocks due to consensus mechanism vulnerabilities or suffers a large-scale DDoS attack, what would Walrus face?
During this period when the Sui mainnet is down, although Walrus storage nodes continue running and disk data remains intact, the entire system's control center loses responsiveness. You cannot apply for new storage quotas, cannot adjust access permission policies, and may even be unable to verify data ownership and access permissions through Sui on-chain contracts. The result is that data falls into a "zombie" state — physically it indeed exists, but logically it becomes inaccessible or uncontrollable.
Particularly problematic are scenarios where permission authentication relies on real-time on-chain verification. For example, applications like "can only decrypt storage files by holding specific NFTs." Once Sui experiences downtime, the entire authentication mechanism collapses, and even users with legitimate permissions cannot access data.
Based on this understanding, when designing businesses with high availability requirements, I would not assume L1 is always stable and online. Instead, I would build a "fallback degradation plan": cache critical metadata and permission snapshots at the application layer. When the Sui network malfunctions, the application can temporarily switch to local verification mode and directly use cached credentials to request data from Walrus nodes — provided that Walrus nodes offer some kind of offline verification capability, or the application layer has backup decryption methods.
To put it plainly, without this kind of "emergency contingency plan that can maintain basic operations while detached from the mainchain," all storage solutions claiming decentralization would appear fragile in the face of mainchain failures.
