I ordered takeout the other day, and it got stolen right when it arrived downstairs.

I went to the property management office to check the security footage. The security guard took forever looking through it, then said the classic line: "We have no idea who this person is."

The platform customer service was equally skilled: "We suggest you place a new order."

I completely lost it right there.

The money was deducted, the food was gone, nobody took responsibility, and the entire process was just a "black hole of evidence."

Later I started thinking: if every delivery had a verifiable record—from the rider accepting the order, arrival time, delivery action—wouldn't all this nonsense go away?

This is actually the kind of problem @Sign is solving.

It's not just about recording data, but making "who did what" into verifiable facts, rather than something people just claim.

Many real-world problems don't actually come from lacking data—they come from data that can't be trusted.

$SIGN basically compresses away the "room for excuses."

In the future, when your food goes missing, instead of arguing with customer service, the system will directly tell you:

who took it. #Sign Geopolitical Infrastructure
