#dusk $DUSK Today I chatted with a friend who is a market maker at @Dusk, and he threw a line at me that left me speechless—"You folks keep shouting about privacy protection, but on-chain privacy isn’t a value-add for a market maker. It’s a survival requirement." I froze for a moment before I realized what he meant.

The market-making business is fundamentally about profiting from information asymmetry. Not the kind of insider information where it’s "I know what you don’t know," but microstructure asymmetry like "you can’t guess how much inventory I still have in my hands." If every limit order you place, every cancel, and every hedging operation is permanently visible on-chain, your counterpart can reverse-engineer your inventory levels and risk exposure—then precisely attack the weak prices where your protection is thin. This isn’t theoretical. In traditional finance, high-frequency market makers will spend millions of dollars building microwave towers—just to see the order flow milliseconds faster than everyone else. On-chain, that information gap is basically wiped out.

At this dimension, Dusk’s Hedger mechanism does something quite subtle: it uses homomorphic encryption to seal the position amount end-to-end. On-chain observers can only see that a transaction happened, but they can’t see the amount or the balance. In effect, it writes a market maker’s "inventory privacy" directly into the protocol layer—not by doing after-the-fact masking like with coin mixers, but by fundamentally preventing the adversary from getting the raw material to infer.

But there’s a contradiction I haven’t fully worked out: market makers want privacy, while regulators want transparency. Can both ends of the rope be pulled at the same time under Dusk’s "selective disclosure" framework? Theoretically, yes—make a backdoor available to regulators, while ordinary market participants can’t see. But in practice, is a market maker willing to expose its inventory data to any third party, even regulators? The psychological threshold isn’t low.

The base position hasn’t moved. I’m still digesting this narrative about market maker privacy, and I’ll only judge once the first batch of real market-making depth data comes out. @Dusk $BTC
