Buying cigarettes does not require an ID, just proving “I am an adult” is enough‼️
Speaking of zero-knowledge proofs in the crypto circle,
🧲 let me tell a little story: Xiao Wang went to the supermarket to buy beer, and the clerk always asked to see his ID, which was super awkward, revealing his age and address, and he had to worry about being photographed and documented.
What if he could just say “I prove that I am an adult,” and the clerk would verify it without seeing any details? Isn’t that nice❓
In reality, this kind of demand is everywhere: renting a house without wanting to expose all income proof, loans without wanting to show all bank statements, and seeing a doctor without letting strangers know the medical history!
Traditional methods are either fully public (awkward + risky) or completely hidden (no proof).
At this point, we need to mention the @MidnightNetwork ’s $NIGHT token, which perfectly solves the problem using zero-knowledge proof (ZK) technology:
The proof is real, but the underlying data is hidden!
Midnight is Cardano's privacy partner chain (side chain), called “the fourth-generation blockchain,” focusing on “rational privacy”: it’s not a black-and-white choice, but rather up to you to decide what to hide and what to reveal.
ZK-SNARKs are like magic: generating a “proof” that others can trust when they verify, but the original data remains confidential forever.
For example:
Proving “I am over 18 to buy alcohol,” without revealing the birthdate or name.
Proving “I made the payment,” while keeping the amount hidden.
Proving the business is “compliant,” without leaking customer data.
NIGHT is a public governance + utility token, with a total supply of 24 billion, used for staking, governance, and generating DUST (privacy-specific resources that shield transaction details, reducing overuse).
Developers can easily write ZK contracts in the Compact language, which has a low threshold. Supported by major exchanges like Binance, with a market cap of around 700-800 million dollars.
Want to be both private and compliant in Web3? Buy some NIGHT and hold it, staking to earn returns, while waiting for the privacy revolution.
