You mail a sealed letter. It travels through two different postal services to reach the other side. Neither one opens it. Both are careful with what they carry. And somebody who wants to know who wrote to whom can still find out.
The leak is at the handoff. When the first service passes the bag to the second, someone writes down which envelope came in, which one went out, and when. Nobody read a word. The link survived anyway.
Money crossing between two systems works the same way. Say you hold value on one network and you want it on a different one. Software called a bridge does that job. A bridge is software that takes your value in on one side, holds it, and releases matching value to you on the other side. Both networks might hide a great deal about their own users. The bridge sits between them and sees both doors.
So grading each network on its own privacy misses the trip. A trip is only as private as its weakest point, and the weakest point is almost always the handoff. I think this gets skipped when people compare two systems side by side, because it belongs to neither one.
The argument on the other side deserves room, and it is a strong one. A handoff that reveals nothing also reveals nothing when something goes missing. If a bridge cannot show that what it released matches what it took in, an outsider has no way to check whether it is issuing claims it cannot back. Every design that has tried to give people privacy across two systems has run into the same question. Who gets to see enough to prove nothing was stolen? Hiding the link and proving the books are honest pull against each other.
What would show me wrong: a handoff running for months where an outside observer can confirm the amount going in matches the amount coming out, and still cannot connect the person on one side to the person on the other.
This is part of why I keep what I own on Bitcoin and leave it there. Every trip to another system adds a handoff, and every handoff is a place where a record of who did what gets written by somebody else. Sitting still is boring. It also adds no handoff.
