At the end of last year, a former colleague suddenly messaged me, saying he had an urgent job and asked me to help make a design draft, with a reward of 500 yuan.

I thought it wouldn't be a problem to help him out. After staying up for two long nights, I sent the final draft over. A month later, this guy came clean, saying that the client was not satisfied with the draft, the final payment was stuck, and he had no money to settle with me.

I was furious! I directly went to check the chat history and discovered that the phrase “500 yuan” was a voice message, and there wasn't even a text screenshot. For 500 yuan, I couldn't escalate the issue, could I? So I had to silently accept being a complete fool.

To be honest, it’s not about the few hundred yuan for me; it’s the helplessness of knowing the other party is being dishonest but having no evidence to confront them with. It’s exhausting.

It’s precisely because I have endured this kind of societal blow that after digging into SIGN recently, I truly empathized in an instant. @SignOfficial

What the Sign Protocol aims to eliminate is precisely this fragile “verbal promise” between people and the subsequent “turning against each other.”

Just think, if I had been more cautious back then and casually used EthSign to throw over a blockchain agreement?

It could have been just a few sentences: “Work content, two-day delivery, reward 500 yuan.” Once both parties confirm, the timestamp and file hash would be firmly etched on the blockchain. No one can retract, no one can tamper.

Even more incredible is its Attestation mechanism. It can transform the working process into individual “on-chain check-in points.” Every time I submit a draft, I check in on-chain; every time he receives it, he confirms. Step by step, this directly forms an ironclad chain of evidence.

When he tries to use “the client is not satisfied” to fool me again? No way. The on-chain delivery records and acceptance times are there, completely eliminating the need for disputes. $SIGN

However, on the flip side, if a friend asks for help and you suddenly pull out an on-chain agreement and say, “Buddy, let’s sign,” it’s indeed hard to say. We’re all still getting used to it.

But this proof mechanism is incredibly useful! After all, many people have experienced exploitation; I’m definitely not the only one.

In the face of interests, human nature cannot withstand the test. Only by using cryptography and on-chain records to protect oneself can one truly feel secure. #SignGeopoliticalInfrastructure
