Recently, many people have been discussing modular architectures in blockchain, but most are entangled in a single question: whose performance metrics look better, whose costs are lower, and whose speed is faster. Listening to this for too long can indeed become a bit dull.

In fact, the concept of modularity in the blockchain field has a more core significance that is often overlooked.

The real financial world is dynamic and constantly changing. Regulatory policies are adjusted, compliance standards are updated, and privacy protection requirements also evolve based on environmental changes. This is not hypothetical; it happens every day. The question is: if a public chain's privacy rules, compliance logic, and transaction execution are all tightly bound together, then any change in one link could trigger risks across the entire system.

DUSK's approach is interesting—it separates privacy, compliance, and execution logic into independent, composable modules. The purpose of this is not to give developers more freedom, but to enable the entire system to better respond to changes.

From another perspective: this is more like "institutional resilience." A region's regulatory environment has new requirements? You only need to adjust the corresponding rule modules, rather than reconstruct the entire chain. It may seem a bit ahead of its time, but if large-scale financial applications are truly to be supported, this kind of design is actually essential.

From this perspective, DUSK is closer to a financial operating system rather than just a public chain for specific applications. The role of modularity here is less about performance optimization and more about risk management.
