What is zkRune?
Prove Without Revealing
Prove you're 18+ without showing ID. Prove you have funds without showing balance.
Math-Based Trust
Data never leaves your device. Mathematical proof can't be faked.Trust the math, not us.
Simple & Fast
No crypto knowledge needed. Pick template, fill form, click button. Ready in 1 second.
💡 Real-World Example:
You want to join an exclusive group that requires members to have at least $10,000 in savings.
Your First Proof in 60 Seconds
No tutorials to read. No docs to dig through. Just three simple steps.
Choose a Template
Pick from 5 ready-made privacy proofs
Age Verification, Balance Proof, etc.

How It Works
Imagine proving you're 18+ without showing your ID. Or proving you have enough money without showing your bank account. That's Zero-Knowledge. Here's how zkRune makes it simple:
Pick What You Want to Prove
Think of templates like different types of IDs. Need to prove you're old enough? Use Age Verification. Prove you have enough money? Use Balance Proof. Just pick what fits.
Like choosing which ID to show
Fill a Simple Form
Enter your private information - like your birth year or balance. Don't worry, this never leaves your browser. It's like writing on paper that only you can see.
As easy as filling out a Google form
Click Generate
Our app does the complex math (zk-SNARKs) behind the scenes. Takes about 5 seconds. You get a proof that says 'Yes, I proved this' without revealing what 'this' actually is.
Like a receipt that proves you paid, without showing your bank account
Share Your Proof
Now you have a proof you can share with anyone. They can verify it's real using math. They'll know you proved what you claimed, but they'll never see your private data.
Like a diploma that proves you graduated, without showing your grades

Frequently Asked Questions
Everything you need to know about zkRune
Think of it like proving you know a secret password without revealing the password itself. In simple terms: you can prove a fact is true (like being over 18) without revealing the underlying data (your exact birth date). It's like showing your ID to a bouncer who only needs to know you're 18+, not your actual birthday.

Understand the technology powering zkRune
Zero-Knowledge
?Prove something is true without revealing why it's true
e.g., Prove you're 18+ without showing your birthday
zk-SNARKs
?Succinct Non-Interactive Arguments of Knowledge - compact proofs
e.g., Tiny proofs that anyone can verify quickly
Shielded
?Zcash's privacy feature that encrypts transaction details
e.g., Your proof deployment is invisible on blockchain
Circom
?Language for writing zero-knowledge circuits
e.g., The code behind ZK proofs (we handle it for you)
