From what I’ve seen, the main idea is to minimize persistent storage. No registration usually means fewer long-term records and more reliance on temporary processing states. That shifts the load toward efficient request routing and quick disposal of data after execution. It’s not necessarily advanced, just a different balance between state and throughput.

I came across a reference to a no KYC crypto exchange https://godex.io/ where the description suggested short data retention and simplified processing chains. It didn’t seem particularly complex, more like a streamlined implementation of standard architecture patterns.
