## Another Path to the Privacy Chain Performance Dilemma

Anyone who has worked on blockchain projects knows that whenever system response slows down, the business and technical teams start blaming each other. One side says the functionality requirements are too complex, the other says the architecture design has issues. Especially in compute-intensive scenarios involving zero-knowledge proof verification, lag problems are even more troublesome.

Recently, I came across Dusk Network's technical solution. Their Piecrust virtual machine adopts an interesting "zero-copy memory" architecture. Simply put—when data is transferred between the host environment and the virtual machine, there is no need to copy; it directly references the data. This may sound minor, but it’s actually a clever approach to solving transmission loss.

How effective is it in practice? During intensive zero-knowledge proof verification, this design makes DUSK Chain’s processing efficiency significantly better than other privacy projects. There’s no common lag feeling. For high-frequency financial applications, this level of smoothness means the user experience can truly keep up with business needs, and business teams won’t have to repeatedly bother the technical team to change requirements—because the system itself can handle it.

From an architectural perspective, this is why privacy chains don’t necessarily have to compromise on performance. The key is how to design and optimize.
