Simply put, the government or bank wants to issue you a certificate. For example: you are a legal citizen, you are eligible to receive a subsidy of 1000 yuan, and you have transferred 5000 yuan to someone else
In the past, they sent paper certificates or electronic files, which were easily lost, altered, or could not be found if the system crashed. What Sign does is super simple and straightforward, just two steps: First step: create a 'blank form' (this is the Schema)
The government first draws a standard form, clearly stating what must be filled in: name, ID number, amount, date, and whether it is legal
This form must be used by everyone in the same format in the future, and no unauthorized changes are allowed. This is the Schema. Second step: fill out the form, then sign and seal (this is the Attestations)
The government enters your information into this form and “signs” it with its private key, turning it into a “digital proof.” This proof is directly linked to you (your wallet address or identity). The really powerful thing is that it has three key features: you can check it whenever you want
Banks, governments, or you yourself can verify at any time whether “this proof is genuine,” and the check is lightning-fast.
If you still don’t get it, let me give you a few more examples
Renting a place
Landlords are most afraid of tenants who lie. With Sign, you can ask a former landlord or your community to sign a “good tenant certificate” for you. It states which places you’ve rented, that you’ve never been late on rent, and that you haven’t damaged anything. The new landlord can scan the code and see that “this person is trustworthy”—no need to make calls and ask around.
Job interviews
HR hates fake degrees and fake work experience. With Sign, your school and former employer each sign a “proof of education” and a “proof of work experience.” When you apply for a job, just send the links to the proofs with your résumé. HR can scan them to see if they’re genuine, and even find out exactly when and where you worked and what you did.
Three ways to keep information private
Public mode: Everyone can see the full content
Private mode: Others can only see “this is genuine,” but can’t see exactly how much money you have or your ID number
Hybrid mode: Make public what should be public, and hide what should be hidden (the most commonly used option). Even if the sky falls, it’ll still work. Even if a bank building explodes, the internet goes down, the strait is blocked, and all traditional systems fail, this digital proof remains on the blockchain. You can still claim your money and prove your identity—it won’t go offline.
What Sign does is this: someone (the government, a bank, a school, or a company) signs a “little digital note” for you. This note can never be lost, can always prove what’s genuine, and can also keep private information you don’t want others to know hidden#Sign地缘政治基建 @SignOfficial $SIGN
