Walrus and Seal as a practical answer to Web3 is public by default
A huge limitation of many Web3 stacks is that they assume data is public, and privacy becomes a custom engineering project. Walrus tackles this head-on with Seal, framing it as native onchain access control for data: developers can protect sensitive data, define who can access it, and enforce those rules entirely onchain.
What makes this useful is the range of real product patterns it unlocks: AI dataset marketplaces with enforced access policies, token-gated subscription content, and even games where encrypted content unlocks only when conditions are met. The deeper point: Walrus isn’t just “decentralized storage.” With Seal, it becomes a way to build data that is both verifiable and controllable, which is exactly what serious Web3 apps need if they want to handle real users, real businesses, and real compliance constraints.
