How to resolve the contradiction between transparent ledgers and personal privacy in the on-chain world?

To be honest, by the year 2025, the evolution of encryption privacy technology has progressed beyond what many people can imagine.

Recently noticed the Beldex project, and their approach is quite interesting - they directly make the privacy layer an on-chain protocol. What does that mean? It means you don't need to manually turn on any "privacy mode"; every transaction inherently hides the information of both parties and the amount details.

This design logic is actually quite clever: instead of letting users choose whether or not they want privacy, it’s better to make anonymity protection the system's default behavior. After all, for most people, who would want their funds' movements exposed on a public ledger?

From optional features to infrastructure, this may be what the next generation of privacy public chains should look like.
