I went into the 21X story thinking the interesting part was trading and settlement happening together. Then I started looking at the rules around that setup, and the Dusk connection became more interesting to me.
21X has its own Rulebook, Pre-Trade Controls and Default Management Policy. That tells me something important about what Dusk is actually building for @Dusk Putting a market onchain doesn't remove the rules around the market. Dusk is providing the infrastructure where those rules, trading activity and settlement can work together.
The Pre-Trade Controls are the part I keep coming back to. They check orders before execution. I like that detail because it shows where the blockchain stops being the whole story. Dusk can provide settlement and execution infrastructure, but the market still needs to decide what should be allowed through in the first place.
Then there’s the Default Management Policy. Someone failing to perform doesn't magically disappear because settlement happens onchain. There still has to be a process for dealing with that mess.
And this changes how I see the 21X connection. Dusk isn't replacing the rulebook with code. At least from what I can see, it's trying to put regulated market activity on infrastructure where execution, privacy and settlement can work closer together.
That makes me wonder about the bigger Dusk idea. Maybe the interesting part of regulated finance going onchain isn't removing all the old rules.
Maybe it's making the rules and the transaction live much closer together.
