Privacy in blockchain systems works best when it adapts to different contexts rather than staying locked at one end of the spectrum. Public blockchains excel at transparency—that's their core strength. However, once genuine financial operations come into play, broadcasting every transaction detail to the entire network becomes problematic. Real-world financial workflows demand selective privacy controls. Institutions and users need the ability to choose what gets exposed and what remains confidential, depending on their specific situation. The sweet spot isn't all-or-nothing privacy; it's flexible, context-aware privacy mechanisms that let different participants operate with appropriate disclosure levels.
