Last night I borrowed a shared power bank. When scanning the code, it said "free," but after returning it, they charged me 39 directly.

I contacted customer service, and they said: "The rules are written on the page."
I checked, and they were there, but hidden in a bunch of fine print.
This is very typical—
rules exist, but lack transparency; execution happens, but can't be disputed.
Many on-chain projects are like this, appearing fair, but details are all black boxes.
But @Sign's approach is to write the rules directly into the system,
who can participate, how it executes—all dependent on credential verification, not on "interpretation rights."
$SIGN isn't making things more complicated, but more certain.
