As blockchain has developed to the present, new concepts are flying everywhere, and many people are already numb to it. But if you really read the technical white paper of a leading privacy public chain project, you'll find that they are indeed tackling hard problems.

What’s most eye-catching is their optimization approach for the Piecrust virtual machine. This is not just a contract execution engine; the core lies in deep low-level optimizations for zero-knowledge proofs. Running privacy computations on traditional public chains? The costs are exorbitant, and the speed is painfully slow. That’s also why privacy coins have not yet seen large-scale adoption. But this project addresses the pain point—maintaining high-efficiency settlement speeds when handling high-concurrency encrypted transactions.

Let’s talk about the consensus mechanism. It ensures decentralization, no doubt, but more importantly, it aligns with financial compliance. In their ecosystem, privacy is not a shield for illegal activities but a genuine business need. Through the Citadel protocol, users can prove they possess certain qualifications—such as being a qualified investor or having completed KYC—without revealing their real identity information.

This "data minimization" design philosophy is precisely the direction of future global privacy regulations. In simple terms, they are building a foundational infrastructure that can both protect privacy and meet regulatory expectations.
