Was up way too late digging into Dusk's slashing mechanics. Something doesn't sit right.
They hide stake amounts to keep the VRF selection random. Makes sense on paper. But slashing requires revealing those amounts to prove the penalty is valid.
Here's where my head hurts: if the stake is hidden until after bad behavior, what stops a validator from shifting that stake via a shielded transfer right before getting caught? The docs claim the state is locked, but that verification lag—even a gap of two or three blocks—creates a window.
You could propose a junk block, pocket the reward, get slashed three blocks later, but the tokens are already gone. The slash just burns an empty account. The chain doesn't revert the block; it just retroactively fines a ghost.
Everyone frames "regulated finance" as the marketing angle for privacy. But honestly? I'm starting to think the identity layer isn't just a compliance checkbox—it's a technical fix for this exact loophole. Without off-chain ID, you can't ban the entity, so the exploit becomes purely economic, and it might actually work.
So is Dusk's KYC/AML stuff really a product differentiator, or is it the actual patch for a temporal gap in their own PoS game theory?
Maybe I'm overthinking the window size. But the documentation hand-waves that part pretty hard. Does state restoration catch this, or is it just a burn-and-forget situation? Genuinely curious if anyone's dug into this deeper.
