Promised to examine how value moves between the two physics.... today, the shielding and unshielding events, becuase every privacy system is weakest at its borders.
The mechanics first. Moving funds from moonlight into phoenix means converting visible account balance into shielded notes, an observable transaction with a visible amount ENTERING the pool. Unshielding is the reverse, notes converting back to public balance, visible amount EXITING. Inside the pool, the graph is broken, daizys note physics from yesterday. At the borders, amounts and addresses stand in daylight.
Why borders leak even when the interior is sealed. Correlation. If 100,000 dusk shields at 09:14 and 100,000 unshields to a fresh address at 09:47, no cryptography was broken.... but any analyst links the two with high confidence. Timing plus amounts plus thin traffic equals deanonymization at the edges. Ziros crowd argument compounds here, a shallow anonymity set makes border correlation nearly trivial.
The defenses the design permits. Amount splitting, shield once, unshield in irregular pieces. Time diffusion, let notes age inside the pool. And above all, POOL DEPTH.... every additional shielded participant makes every correlation weaker. Privacy on dusk is genuinely collective infrastructure, each users caution protects the others.
The institutional angle worth stating, a venue routing regular settlement through phoenix creates rhythmic border traffic, and rhythms are signatures. Serious confidentiality requires operational discipline AROUND the cryptography, not just inside it.
The open item, wether wallet tooling automates any of this hygiene or leaves it to users. Tooling determines wether best practice is default practice. Checking next.
