Privacy issues in decentralized storage have always been a pain point. Walrus Protocol's Seal feature directly addresses this problem — as the first storage platform with built-in access control, it can encrypt data and precisely specify access permissions, with on-chain mechanisms ensuring these permissions are strictly enforced. This solution is particularly suitable for scenarios with high privacy requirements, such as health data management and advertising transaction markets. CUDIS and Alkimi have already validated the feasibility of this model in practical applications.

From a token perspective, $WAL's role in the entire ecosystem is becoming increasingly critical. Storage payments require WAL, node staking requires WAL, and governance voting also requires WAL. As compliance and privacy demands continue to grow, the token demand driven by these practical applications will become stronger. In the short term, it is about functional innovation; in the long term, the genuine necessity attributes will gradually emerge, which is worth paying attention to.
