Most systems confuse data permanence with data availability. Data that is permanently stored does not guarantee that it will be present during critical interactions like settlement, verification, or dispute resolution. @Walrus 🦭/acc introduces time-bound availability windows that ensure data exists when it needs to, not just in theory. This distinction matters for marketplaces, financial apps, RWA tokenization, enterprise workflows and compliance systems where timing matters as much as storage. The $WAL token supports this availability lifecycle through incentives. #Walrus
