"Hey Bro, Recently I read your Zkpass Article, it was good but too complex, tell me how the Zkpass verification works?"
Bro, think about the Blue Checkmark on Instagram or Twitter (before you could just buy it 😭).
When you see that Blue Check, you know that person is "Verified." Twitter checked their ID, confirmed they are real, and gave them a badge. You trust the badge without needing to see their actual Passport or ID card yourself.
Zkpass is basically a DeFi Blue Checkmark for everything else in your life.
Here is the problem: You want to prove to a Crypto App (like a lending protocol) that you have ₹100,000 in your State Bank of India account so you can get a loan.
Method A (The Screen Share): You try to show them a screenshot. Fail. Why? because you can right-click "Inspect Element" and change your balance to $1 Billion in 5 seconds. Screenshots are worthless.
Method B (The Password): You give the Crypto App your username and password so they can check. Fail. You are never going to do that. That's an insane security risk.
Zkpass is the third option. It acts like a Blind Notary.
It sits in the middle while you log in to your bank.
The Handshake: It verifies that you are definitely connected to the real statebankofindia.com (checks the SSL certificate).
The Witness: It watches the data come down the pipe to your computer.
The Stamp: It puts a mathematical stamp on that data saying "Yes, this data came from the Bank."
The Privacy: Crucially, it doesn't store or leak your password. It just stamps the specific fact (Balance > $10k).
Okay, but how does it actually work?
It uses something called Three-Party TLS (Transport Layer Security).
Normally, when you visit a website, it’s a 2-party secret tunnel: You <--> Website.
Zkpass breaks this rule slightly. It uses MPC (Multi-Party Computation) to split the encryption key.
Part of the key is with you.
Part of the key is with the Zkpass Node.
This means Zkpass can "see" that the data is authentic (signed by the bank), but because it doesn't have the whole key, it can't steal your session or make trades for you. It generates a Zero-Knowledge Proof (a receipt) that you can hand to the Smart Contract.
Right now, you are a ghost in crypto. You have no history. With Zkpass, you can bring your Real World Reputation on-chain.
Prove you are an Uber driver with a 5.0 rating (to get a car loan on-chain).
Prove you own a specific NFT on a different chain.
Prove you are a US Citizen (for regulations) without uploading your passport photo to a shady server.
