To be honest, when I first saw the SIGN documentation, the image that popped into my mind was particularly absurd—a judge taking off his wig, staring at the hash value on the screen for a long time, then banging the gavel: "The evidence is conclusive, the chain records show that you indeed stole that kilowatt hour."
This is not a sci-fi movie. @SignOfficial is doing exactly what turns the question of "what is true" from "human judgment" into "cryptographic computation."
How is this achieved? The core consists of two things: Schema and verification primitives.
What is Schema? It is the standardized template that SIGN designs for “facts.” When you say “this citizen is legitimate,” SIGN doesn’t allow you to write it casually; you must fill it in according to a fixed data structure—who issued the certificate, at what time, based on what basis, and valid until what date. Each field is strictly defined, machine-readable, and algorithm-verifiable.
What are verification primitives? They are the capability of SIGN to transform matters of the physical world into cryptographic evidence. For instance, in terms of electricity consumption data, previously, whatever the power supply bureau said was the truth, how could you prove you didn’t use that much? SIGN can design a set of processes: smart meter real-time readings → on-chain signatures → generating immutable hashes. Who wants to alter the data? First, crack the cryptography and then talk.
The Internet Court of China recognized the validity of blockchain evidence back in 2018. The Supreme People’s Court clearly stated: Evidence that is preserved through digital signatures, timestamps, and hash value verification is recognized by the court.
I have to be clear: SIGN is not trying to eliminate the court; it is eliminating the wrangling over “who is lying.”
When the electricity consumption, asset transfers, and compliance certificates of the physical world are turned into verifiable hash values by SIGN, you will notice an interesting change: the core of lawsuits shifts from “proving that what I said is true” to “proving that I did not lie.”
The former requires judges to act as detectives, while the latter only requires judges to act as referees.
This is the truly terrifying aspect of SIGN—it is not just about technology; it is redefining “what constitutes evidence.”
This job used to be done by the courts. Now, code has also begun to take it on.
