Recently, I heard a story about an old-school OTC trader in the circle. As soon as the money arrived on his card, it was frozen. The next day, he went in for a chat. The charge? Aiding and abetting. He thought he was just selling some Bitcoin, but it turned out to be money from telecom fraud, leaving him with no defense.

This incident made me think for a long time—no matter how sophisticated your on-chain play is, once you touch fiat in the physical world, you're running naked. ZBT's job is to armor this last mile.
Its logic isn't complicated: use TEE (Hardware Security Module) to lock transaction data so miners can't see what's inside; then use ZKP (Zero-Knowledge Proof) to put a receipt on the chain, proving the transaction is clean without revealing who you traded with or how much.
The key is in the node design. Want to run a ZBT node and earn fees? First, stake real stablecoins as a token of commitment. If you cheat or go offline, the system directly confiscates your funds. Binding security with the most primitive capital logic is much more practical than just shouting slogans.
The old-timer ended up spending nearly 10% of his holdings to settle this matter. Looking back, if he had used privacy infrastructure like $ZBT , proving the source of funds clean with zkLogin without exposing his bottom line, would it have come to this?
In this era where there are more cameras than people and big data is everywhere, without physical-level privacy protection, so-called anonymity is just swimming naked under surveillance.
