Piecrust VM Made Me Rethink What Smart Contract Privacy Could Look Like
Reading through Dusk's whitepaper, something clicked for me that I hadn't really considered before: privacy isn't just about hiding a transaction amount. It's a bigger question than that why should a smart contract's logic and data be exposed to the entire world just because it's running on a public chain?
That's what pulled my attention toward Piecrust, Dusk's WASM based virtual machine.
From what I can tell, Piecrust isn't just there to execute contracts it's built with confidentiality baked into how execution itself works. Dusk doesn't stop privacy at the transaction layer and call it done. It pushes that same idea down into the execution layer, so a contract's internal logic or sensitive data doesn't have to become public just because the contract ran...
Honestly, that's the part I keep coming back to. On most chains I've looked at, privacy tends to get bolted on afterward an external tool, a rollup, a separate protocol layered on top. @Dusk seems to be doing something different by treating privacy as part of the execution environment from day one, not an add on. If regulated institutions ever want to actually run business logic on a blockchain, that distinction feels like it matters a lot more than people give it credit for.
But I'll be upfront about where I got stuck. The whitepaper walks through the architecture clearly, yet I couldn't find real benchmarks nothing on execution speed, developer experience, or how it holds up at scale. Until someone tests that under real load, it's hard for me to say whether this design actually delivers, or just sounds good on paper...
So here's what I keep asking myself: should smart contracts default to fully transparent, or should confidentiality be the norm whenever privacy is actually needed?
