When it comes to privacy, many assume a fully private blockchain is the only way to go. But that's actually overkill for most scenarios. The truth is, only certain applications and specific transactions really need that level of secrecy—not everything across the board.

Here's the catch: going all-in on chain-wide privacy comes with real costs. You lose transparency, and the ability for different protocols to work together becomes a nightmare. It's like putting everyone in the dark to hide one person's business.

Application-level privacy, though? That's a different beast entirely. It lets you be selective. You get privacy exactly where you need it, while keeping the rest of the ecosystem transparent and composable. It's more flexible, more practical, and honestly, way more useful for real-world use cases.
