Recently, I experienced writing smart contracts on a privacy public chain. To be honest, the most challenging part isn't the new concept itself, but whether the supporting tools keep up.

Dusk's approach is quite interesting — it aims to make privacy capabilities the foundational layer of the chain, rather than having application developers assemble it themselves on the upper layers. This makes a huge difference for those writing contracts. You don't need to repeatedly design zero-knowledge proof logic, nor worry about security boundaries; you can directly invoke underlying capabilities and fully focus on business contracts and risk control design. It sounds perfect in theory.

But in reality, this path is easy to stumble on. How well the documentation is written, whether the SDK is user-friendly, how smooth the debugging experience is — if any of these links are broken, developers won't want to migrate, and no matter how advanced the underlying design is, it won't be used.

Ultimately, the long-term value of this coin isn't determined by the loudest advocates, but by whether "developers are really building products." I'm currently focusing on one metric: developer retention rate within the ecosystem. This is the only standard to test all promises.
