Last night at Pazhou, we had claypot porridge, and Old Li once again showcased his "urine escape" technique during the checkout process. He shouted, "I’ll take care of it!" while pretending to pull out his phone, confident that we would stop him. As a result, his so-called Web3 social app suddenly erupted with a loud noise: "Transaction Witness Confirmed! (交易见证已确认)".
Everyone at the table was stunned. To show off, Old Li posted a "Generosity Attestation" with the number @SignOfficial in the DID social protocol. His intention was to create a fake credit score to deceive investors in future management.
1. The awkward "reveal": When courtesy meets Schema
Old Li had preset a logic in the Schema (Unified Architecture) of $SIGN : as long as an intention to "pay the bill" was initiated within the geographical fence of a roadside stall, and there were more than 3 associated friends nearby, a "bill payment witness" would be automatically generated.
He thought this was just a display name, but the signing logic was extremely hardcore. If you dared to issue this witness, the system automatically assumed you had made a "payment commitment." At that moment, without us needing to act, Old Li’s account, connected to a smart contract, triggered a Hook, bypassing his confirmation, and precisely deducted the 888 yuan for the porridge from the boss's address.
2. SIGN: The "courtesy nemesis" that shows no mercy
Old Li looked at the deduction notification popping up on his phone, his face turning the color of pig liver. This is the harshest part of SIGN: it solidifies all vague "human courtesy" into an immutable mathematical matrix.
Do you think you can use the mystique of "courtesy" to combat ZK-Attestation (zero-knowledge proof)? No way! Although the system protects your privacy (it didn’t let the table next to you know you only have 1000 yuan left), it 100% confirmed one fact: you initiated the witness, and the logic must close the loop.
I am Little Fish, and I choose to be a trustworthy person in the light and shadow of the Sign Protocol. As for Old Li? Haha, he’s staring at that bowl of porridge, nearly crying from the heartbreak.
